Wherein the evaporation element 300 is provided with an evaporation cavity 310. And, the evaporation element 300 is fitted in thermal contact with the heat exchange body 200, so that the heat generated from the heat exchange body 200 can be transferred into the evaporation chamber 310.

As shown in fig. 3 to 6, the evaporation element 300 may be in the form of an evaporation box, the evaporation box may be sleeved outside the outer sidewall of the heat exchange body 200, and a space between the outer sidewall of the heat exchange body 200 and the outer sidewall of the evaporation box may form an evaporation cavity 310; as shown in fig. 7 to 9, the evaporation element 300 may also be in the form of a tube coil, which may be coiled along the circumference of the heat exchange body 200, and the inner cavity of the tube coil is the evaporation cavity 310; it is only necessary to transfer the heat generated by the heat exchange body 200 to the evaporation cavity 310 to evaporate the condensed water.

The evaporation element 300 may be separately provided outside the combustor 210, may be separately provided outside the heat exchanger 220, may be provided outside both the combustor 210 and the heat exchanger 220, and may be flexibly designed or adjusted according to actual use requirements. Preferably, the evaporation element 300 is disposed at the outer side of the burner 210 and the outer side of the heat exchanger 220, and has a good evaporation effect on the condensed water.

Wherein, utilize water conservancy diversion subassembly 400 can communicate condensation box 100 with evaporation chamber 310 to make the comdenstion water in the condensation box 100 flow into in the evaporation chamber 310, the comdenstion water that flows into in the evaporation chamber 310 receives the heat that comes from heat transfer main part 200 and evaporates into vapor, vapor in the evaporation chamber 310 gets back to in the condensation box 100 under the water conservancy diversion of water conservancy diversion subassembly 400 and discharges to the external world from exhaust port 120 with the high temperature flue gas after the heat transfer is accomplished together, thereby realize not having the comdenstion water and discharge. In addition, the heat of the heat exchange body 200 is absorbed by the condensed water in the evaporation cavity 310, so that the temperature of the outer side wall of the heat exchange body 200 can be reduced, and overheating can be avoided.

As shown in fig. 3, 5, 7, and 9, optionally, the flow guide assembly 400 includes a first flow guide tube 410 having a predetermined inner diameter.

Wherein, the first guide pipe 410 is used for communicating the condensation box 100 with the evaporation chamber 310. Also, the first flow conduit 410 is capable of transporting both steam and condensed water. Thus, the condensed water in the condensation box 100 flows into the evaporation cavity 310 through the first flow guide tube 410 and is thermally absorbed into water vapor in the evaporation cavity 310, and the water vapor flows back into the condensation box 100 through the first flow guide tube 410 and is discharged from the smoke outlet 120.

The preset inner diameter of the first flow guide pipe 410 can be flexibly adjusted or designed according to actual use requirements, and only the requirement that condensed water and water vapor can be conveyed simultaneously is met.

Specifically, the evaporation element 300 is disposed at an obliquely lower position of the condensation box 100, and the first guide pipe 410 is disposed obliquely, so that the condensed water flows into the evaporation chamber 310 through the first guide pipe 410 by gravity, and the water vapor also rises into the condensation box 100 through the first guide pipe 410.

As shown in fig. 4 and 8, the flow directing assembly 400 optionally includes a second flow conduit 420 and a third flow conduit 430.

Wherein, the evaporation element 300 has a water inlet and an air outlet, both of which are communicated with the evaporation cavity 310. And the air outlet is arranged above the water inlet.

Specifically, the second guide pipe 420 is used to communicate the water inlet with the condensation box 100, and the third guide pipe 430 is used to communicate the air outlet with the condensation box 100. In this way, the condensed water in the condensation box 100 enters the evaporation chamber 310 from the water inlet through the second flow guide tube 420 and is transformed into water vapor in the evaporation chamber 310, and the water vapor flows back to the condensation box 100 from the air outlet through the third flow guide tube 430 and is discharged from the smoke outlet 120. In addition, the second guide pipe 420 and the third guide pipe 430 respectively transmit the condensed water and the water vapor, so that the transmission of the condensed water and the water vapor is not interfered with each other, the flow is smoother, and the blockage is avoided; the second draft tube 420 and the third draft tube 430 can be designed to be thin, so that the cost is saved, and the arrangement and installation of pipelines are facilitated.

More specifically, the water inlet and the air outlet are opened at the same side position of the evaporation element 300, the air outlet is positioned above the water inlet, the second guide pipe 420 communicates the bottom of the condensation box 100 with the water inlet, so that the condensed water flows into the evaporation chamber 310, and the third guide pipe 430 communicates the upper sidewall of the condensation box 100 with the air outlet, so that the water vapor flows into the condensation box 100.

As shown in fig. 5 and 9, the water amount detecting element 600 is used for acquiring an actual amount of the condensed water in the evaporation chamber 310, so that the actual amount of the condensed water in the evaporation chamber 310 can be detected in real time by the water amount detecting element 600 and the detection result is transmitted to the control element, thereby providing a basis for subsequent processing of the condensed water.

Wherein, the water detection element 600 can be a liquid level sensor for detecting the liquid level, and also can be a water pressure sensor for detecting the water pressure, and can be fixed on the inner side wall of the evaporation cavity 310 through modes such as splicing or screw connection, and only needs to satisfy the requirement that the actual water amount of the condensed water can be detected.

The water replenishing assembly 500 is used for performing water replenishing treatment on the evaporation cavity 310, so that when the water amount detecting element 600 detects that the condensed water in the evaporation cavity 310 is too little, the control element controls the water replenishing assembly 500 to work, so that the water replenishing treatment is performed on the evaporation cavity 310, and the overheating problem caused by too little condensed water in the evaporation cavity 310 is avoided.

Specifically, the water replenishing assembly 500 can be selectively communicated with or cut off from the evaporation cavity 310, so that the control element can select whether the water replenishing assembly 500 is communicated with or cut off from the evaporation cavity 310 according to actual needs, water can be timely replenished, and excessive water replenishing can be avoided.

As shown in fig. 3 to 5 and 7 to 9, in particular, in the embodiment of the present application, the water replenishing assembly 500 includes a water replenishing pipe 510 and a switch valve 520 for controlling the on/off of the water replenishing pipe 510. The water replenishing pipe 510 is used for communicating a water source with the evaporation cavity 310, and the switch valve 520 is electrically connected with the control element. Thus, when the water amount detecting element 600 detects that the condensed water in the evaporation cavity 310 is too little, the control element controls the switch valve 520 to be opened, so that the water at the water source enters the evaporation cavity 310 through the water replenishing pipe 510, and then the water can be replenished to the evaporation cavity 310, thereby avoiding the overheating problem caused by too little condensed water in the evaporation cavity 310.

The switch valve 520 may be an existing valve body such as an electromagnetic valve, and may be packaged in the water replenishing pipe 510 in a manner of plugging and the like.

In addition, the refill assembly 500 may further include a filter element (not shown). The filter element is disposed in the water replenishing pipe 510 to filter water passing through the water replenishing pipe 510. Therefore, in the water replenishing process, water is filtered by the filter element, and the influence or interference on the heat absorption and evaporation of the evaporation element 300 caused by the impurities in the water entering the evaporation cavity 310 is avoided.

The filter element can be an element capable of filtering impurities in water, such as a filter membrane material or a filter screen. The filter element can be packaged in the water replenishing pipe 510 in a screwing or splicing mode.

Further, the refill assembly 500 further includes a flow rate detecting element (not shown). Wherein, the flow detection element is arranged in the water replenishing pipe 510 to detect the flow of the water passing through the water replenishing pipe 510, and the flow detection element is electrically connected with the control element. Therefore, the flow of water flowing through the water replenishing process is detected through the flow detecting element, the detection result is transmitted to the control element, and the control element is combined with the detection of the actual water quantity in the evaporation cavity 310 by the water quantity detecting element 600, so that the switch valve 520 can be accurately judged to be closed, the accurate water replenishing of the evaporation cavity 310 is realized, and the excessive or insufficient water replenishing is avoided. Of course, in other embodiments, the control unit may determine when to close the on-off valve 520 based on the flow information detected by the flow detecting unit alone or based on the actual water amount detected by the water amount detecting unit 600 alone.

The flow rate detecting element may be a flow rate sensor or a flow rate probe.

Wherein, the water removal component is used for carrying out water removal treatment to the evaporation cavity 310, so, when the water detection element 600 detects the too much comdenstion water in the evaporation cavity 310, the control element control water removal component work to carry out water removal treatment to the evaporation cavity 310, avoid taking place to flow backward into the problem of mouth 110 because of the too much comdenstion water in the condensation box 100.

It should be noted that when the water amount detecting element 600 detects that the condensed water in the evaporation cavity 310 is too much, it indicates that the condensed water accumulated or generated in the condensation box 100 is too much, so that there is a risk that the condensed water flows back to the smoke inlet 110.

Wherein, the removal of dewatering subassembly to the comdenstion water can be realized through the form of heating evaporation, also can realize through the mode that restraines the comdenstion water and produce, only need satisfy can get rid of the comdenstion water in order to avoid flowing backward the problem can.

As shown in fig. 6, the water removal assembly optionally includes an auxiliary heating element 900. Wherein, the auxiliary heating element 900 is disposed in the evaporation cavity 310 to heat the condensed water. So, when the water detection element 600 detects the comdenstion water in the evaporation chamber 310 too much, the control element control auxiliary heating element 900 is opened and is carried out the auxiliary heating to the comdenstion water, combines heat transfer main part 200 to the heating evaporation of comdenstion water, has accelerated the evaporation rate of the comdenstion water in the evaporation chamber 310, and then can reduce the water yield of comdenstion water fast, avoids the comdenstion water to flow backward to the mouth of intaking 110.

The auxiliary heating element 900 may be an electric heating wire, an electric heating rod, or the like, which can heat the condensed water to promote evaporation, and may be fastened or screwed to the inner sidewall of the evaporation chamber 310.

In practical use, when the ambient temperature is low, the condensed water in the evaporation cavity 310 may freeze, which affects the adjustment of the condensed water. Therefore, the first temperature detection element can be used for detecting the ambient temperature, the first temperature detection element is electrically connected with the control element, the detected ambient temperature is transmitted to the control element, and when the ambient temperature detected by the first temperature detection element is lower than a preset ambient temperature value, the control element can open the auxiliary heating element 900 to perform auxiliary heating on the condensed water in the evaporation cavity 310, so that the condensed water in the evaporation cavity 310 can be prevented from freezing.

The preset ambient temperature value may be flexibly adjusted or designed according to actual use requirements, and is not limited herein.

The first temperature detecting element may be a temperature sensor or other components capable of detecting the ambient temperature and transmitting the detection result to the control element. The first temperature detecting element may be fixedly disposed on the outer sidewall of the heat exchanging body 200 by means of inserting or screwing.

In addition, can also utilize the second temperature detect element to detect the heat transfer temperature in the heat transfer intracavity, utilize the electric connection of second temperature detect element and control element to transmit the heat transfer temperature that detects to control element, when the heat transfer temperature that the second temperature detect element detected is less than when predetermineeing heat transfer temperature, control element then can open auxiliary heating element 900 in order to carry out the auxiliary heating to the heat transfer chamber of heat exchanger 220, thereby can avoid the heat transfer temperature in the heat transfer intracavity to hang down and influence heat exchange efficiency. In addition, the auxiliary heating element 900 may be used to preheat the combustion chamber of the burner 210, so as to improve the combustion efficiency.

The preset heat exchange temperature can be flexibly adjusted or designed according to actual heat exchange needs, and is not limited herein.

The second temperature detection element may be a temperature sensor or other component capable of detecting the temperature in the heat exchange cavity and transmitting the detection result to the control element. The second temperature detection element can be fixedly arranged on the inner side wall of the heat exchange cavity in a splicing or screw connection mode and the like.

As shown in fig. 5 and 9, optionally, the water removal assembly includes a water inlet pipe 710, a condensation heat exchange pipe 720, a water outlet pipe 730 and a bypass assembly 800.

Specifically, the condensation heat exchange tube 720 is disposed in the condensation box 100 by inserting, and when the high temperature flue gas contacts the condensation heat exchange tube 720, condensed water can be generated. The inlet pipe 710 and the outlet pipe 730 are disposed outside the condensation box 100. And, the condensing heat exchanging pipe 720 serves to communicate the water inlet pipe 710 with the water outlet pipe 730.

More specifically, the water inlet pipe 710 is used for communicating a water source with the condensing heat exchange pipe 720, and the water outlet pipe 730 is used for communicating the heat exchanger 220 with the condensing heat exchange pipe 720.

Meanwhile, the bypass assembly 800 is disposed outside the condensation box 100. Furthermore, the bypass assembly 800 can control the degree of communication between the inlet pipe 710 and the outlet pipe 730. Thus, when the water amount detecting element 600 detects that the condensed water in the evaporation cavity 310 is too much, the control element controls the bypass assembly 800 to open, so that the water inlet pipe 710 is directly conducted with the water outlet pipe 730, thereby reducing the amount of water entering the condensation heat exchange pipe 720, further reducing the amount of condensed water generated in the condensation box 100, and preventing the condensed water from flowing back to the smoke inlet 110. In addition, in combination with the continuous evaporation consumption of the condensed water in the evaporation cavity 310, the amount of the condensed water can be effectively reduced, and the condensed water can be better prevented from flowing backwards to the smoke inlet 110. Moreover, the control element is utilized to accurately control the conduction degree, so that the water quantity entering the condensation heat exchange tube 720 can be accurately regulated and controlled, and the heat exchange efficiency and the backflow risk of the second heat exchange are balanced.

Wherein, the control of the conduction degree can be realized by controlling the size of the conduction opening.

As shown in fig. 5 and 9, in particular, in the embodiment of the present application, the bypass assembly 800 includes a bypass pipe 810 and a bypass valve 820 for controlling the degree of conductance of the bypass pipe 810. Wherein, the two ends of the bypass tube 810 are respectively communicated with the water inlet tube 710 and the water outlet tube 730. The bypass valve 820 is electrically connected to the control element. Thus, when the water amount detecting element 600 detects that the condensed water in the evaporation cavity 310 is excessive, the control element controls the opening degree of the bypass valve 820, so as to regulate the conduction degree of the water inlet pipe 710 and the water outlet pipe 730, further control the amount of the condensed water, and prevent the condensed water from flowing backward to the smoke inlet 110.

For example, when the amount of the condensed water exceeds a large amount, the control element controls the bypass valve 820 to open a large opening, so that the amount of the water entering the condensation heat exchange pipe 720 is greatly reduced, the amount of the condensed water in the condensation box 100 can be greatly reduced, and the condensed water is prevented from flowing backwards to the smoke inlet 110; when the condensed water exceeds a small amount, the control element controls the bypass valve 820 to open a small opening, so that the amount of the condensed water entering the condensation heat exchange pipe 720 is reduced, the amount of the condensed water in the condensation box 100 can be reduced, the condensed water can be prevented from flowing backwards to the smoke inlet 110, and the secondary heat exchange efficiency can be ensured.

The bypass valve 820 may be an existing valve body such as an electromagnetic valve, and may be enclosed in the bypass pipe 810 by means of insertion or the like.

It should be noted that, in actual use, the auxiliary heating element 900 may be used alone to avoid backflow, the bypass assembly 800 may be used alone to avoid backflow, and the auxiliary heating element 900 and the bypass assembly 800 may be used together to avoid backflow.

As shown in fig. 1 and fig. 2, in an embodiment, a condensed water control method is further provided, which can accurately adjust condensed water of the condensing gas heat exchanger, so as to avoid overheating or backflow.

Specifically, the condensate water control method at least comprises the following steps:

s100, acquiring the actual water quantity of the condensed water in the evaporation cavity 310.

Specifically, the water amount detecting element 600 can detect the actual amount of the condensed water in the evaporation cavity 310 in real time and transmit the detection result to the control element, so as to provide a basis for the subsequent treatment of the condensed water.

And S200, if the actual water amount is less than the first preset water amount, performing water supplementing treatment on the evaporation cavity 310.

Specifically, when the water amount detecting element 600 detects that the actual amount of the condensed water in the evaporation cavity 310 is smaller than the first preset amount of water, which indicates that the condensed water in the evaporation cavity 310 is too little, the control element is utilized to control the water replenishing assembly 500 to operate, so that the water replenishing treatment is performed on the evaporation cavity 310, and the overheating problem caused by too little condensed water in the evaporation cavity 310 is avoided.

More specifically, in step S200, the method includes: s210, the water replenishing pipe 510 is controlled to be communicated with the evaporation cavity 310 until the actual water amount is equal to the first preset water amount.

In particular, in the embodiment of the present application, the refill assembly 500 includes a refill pipe 510 and an on-off valve 520 for controlling the opening and closing of the refill pipe 510. The water replenishing pipe 510 is used for communicating a water source with the evaporation cavity 310, and the switch valve 520 is electrically connected with the control element. So, when the actual water yield that water quantity detecting element 600 detected the comdenstion water in the evaporation chamber 310 is less than first predetermined water yield, the comdenstion water in the evaporation chamber 310 of expression is too little, and control element control switch valve 520 is opened for moisturizing pipe 510 switches on with evaporation chamber 310, and the water of water source department passes through moisturizing pipe 510 and gets into in the evaporation chamber 310, and then can carry out the moisturizing to evaporation chamber 310, avoids taking place the overheat problem because of the comdenstion water in the evaporation chamber 310 is too little. When the water amount detecting element 600 detects that the actual amount of the condensed water in the evaporation chamber 310 is equal to the first preset amount of water, the control element controls the on-off valve 520 to close, so that the water replenishing pipe 510 is cut off from the evaporation chamber 310.

S300, if the actual water amount is larger than the second preset water amount, performing water removal treatment on the evaporation cavity 310. Wherein the second preset water amount is larger than the first preset water amount.

Specifically, when the water amount detecting element 600 detects that the actual amount of the condensed water in the evaporation cavity 310 is greater than the second predetermined amount of water, which indicates that the condensed water in the evaporation cavity 310 and the condensation box 100 is excessive, the control element is utilized to control the water removing assembly to operate, so as to remove water from the evaporation cavity 310, and avoid the problem of backflow into the smoke inlet 110 due to excessive condensed water in the condensation box 100.

In one embodiment, in step S300, which includes S310, the auxiliary heating element 900 in the evaporation chamber 310 is controlled to be turned on to perform auxiliary heating on the condensed water until the actual water amount is less than or equal to the second preset water amount.

Specifically, the water removal assembly includes an auxiliary heating element 900. Wherein, the auxiliary heating element 900 is disposed in the evaporation cavity 310 to heat the condensed water. So, when the actual water yield that water yield detecting element 600 detected the comdenstion water in evaporation chamber 310 was greater than the second and predetermines the water yield, it is too much to show the comdenstion water in evaporation chamber 310 and the condensation box 100, and control element control auxiliary heating element 900 is opened and is carried out the auxiliary heating to the comdenstion water for the evaporation rate of the comdenstion water in evaporation chamber 310, and then can reduce the water yield of the comdenstion water in evaporation chamber 310 and the condensation box 100, avoid the comdenstion water to flow backward to advancing cigarette mouth 110. When the water amount detecting element 600 detects that the actual amount of the condensed water in the evaporation cavity 310 is less than or equal to the second preset amount of water, the control element controls the auxiliary heating element 900 to be turned off, so that the water replenishing pipe 510 and the evaporation cavity 310 are cut off.

In practical use, when the ambient temperature is low, the condensed water in the evaporation cavity 310 may freeze, which affects the adjustment of the condensed water.

Optionally, in step S310, the method further includes S311, detecting an ambient temperature, and controlling the auxiliary heating element 900 in the evaporation cavity 310 to be turned on for auxiliary heating when the ambient temperature is lower than a preset ambient temperature value. Therefore, the first temperature detection element is used for detecting the ambient temperature, the first temperature detection element is electrically connected with the control element, the detected ambient temperature is transmitted to the control element, and when the ambient temperature detected by the first temperature detection element is lower than a preset ambient temperature value, the control element can open the auxiliary heating element 900 to perform auxiliary heating on the condensed water in the evaporation cavity 310, so that the condensed water in the evaporation cavity 310 can be prevented from freezing.

Optionally, in step S310, the method further includes: s312, detecting the heat exchange temperature in the heat exchange cavity, and controlling the auxiliary heating element 900 in the evaporation cavity 310 to be started to perform auxiliary heating on the heat exchange cavity when the heat exchange temperature is lower than a preset heat exchange temperature value. So, utilize the second temperature detecting element to detect the heat transfer temperature in the heat transfer chamber, utilize the electric connection of second temperature detecting element and control element, thereby transmit the heat transfer temperature that detects to control element, when the heat transfer temperature that the second temperature detecting element detected is less than when predetermineeing the heat transfer temperature, control element then can open auxiliary heating element 900 in order to carry out the auxiliary heating to the heat transfer chamber of heat exchanger 220, thereby can avoid the heat transfer temperature in the heat transfer chamber to hang down and influence heat exchange efficiency. In addition, the auxiliary heating element 900 may be used to preheat the combustion chamber of the burner 210, so as to improve the combustion efficiency.

In another embodiment, step S300 includes opening the bypass tube 810 such that the amount of water in the inlet tube 710 is reduced and the amount of water in the outlet tube 730 is increased, S320.

Optionally, the water removal assembly includes a water inlet pipe 710, a condensation heat exchange pipe 720, a water outlet pipe 730 and a bypass assembly 800.

Specifically, the condensation heat exchange tube 720 is disposed in the condensation box 100 by inserting, and the water inlet tube 710 and the water outlet tube 730 are disposed outside the condensation box 100. And, the condensing heat exchanging pipe 720 serves to communicate the water inlet pipe 710 with the water outlet pipe 730.

In particular to the embodiments of the present application, the bypass assembly 800 includes a bypass tube 810 and a bypass valve 820 for controlling the degree of conductance of the bypass tube 810. Wherein, two ends of the bypass pipe 810 are respectively communicated with the water inlet pipe 710 and the water outlet pipe 730. The bypass valve 820 is electrically connected to the control element. Thus, when the water amount detecting element 600 detects that the condensed water in the evaporation cavity 310 is excessive, the control element controls the opening degree of the bypass valve 820, so as to regulate the conduction degree of the water inlet pipe 710 and the water outlet pipe 730, further control the amount of the condensed water, and prevent the condensed water from flowing backward to the smoke inlet 110.

For example, when the amount of the condensed water exceeds a large amount, the control element controls the bypass valve 820 to open a large opening, so that the amount of the water entering the condensation heat exchange tube 720 is greatly reduced, and further, the amount of the condensed water generated in the condensation box 100 can be greatly reduced, and the condensed water is prevented from flowing backwards to the smoke inlet 110; when the condensed water exceeds a small amount, the control element controls the bypass valve 820 to open a small opening, so that the amount of the condensed water entering the condensation heat exchange pipe 720 is reduced, the amount of the condensed water in the condensation box 100 can be reduced, the condensed water can be prevented from flowing backwards to the smoke inlet 110, and the secondary heat exchange efficiency can be ensured.

It should be noted that the first preset water amount and the second preset water amount can be flexibly adjusted or designed according to actual use requirements, and are not limited herein, and only the requirements that overheating and backflow cannot occur are met.

The condensate water is regulated and controlled more accurately, so that the problem of overheating or backflow is avoided. As shown in fig. 2, optionally, in step S100, the method further includes:

s110, acquiring the working condition of the condensing gas heat exchange device and detecting the temperature of the evaporation cavity 310. So, operating condition through to condensing gas heat transfer device detects and detects the temperature to evaporation chamber 310, combines the actual water yield of comdenstion water, thereby need utilize moisturizing subassembly 500 to carry out the moisturizing with corresponding judgement to different operating condition and corresponding temperature information and handle evaporation chamber 310, still need utilize the dewatering subassembly to carry out dewatering to evaporation chamber 310 and handle, make the regulation and control of comdenstion water more accurate, can effectually avoid appearing overheated or the problem of flowing backward.

Specifically, S120a, if the condensing gas heat exchanger is in the on state, and the temperature of the evaporation cavity 310 is the first preset temperature value, and the actual water amount is smaller than a third preset water amount, performing water supplementing treatment on the evaporation cavity 310, where the third preset water amount is smaller than the first preset water amount. Thus, when the condensing gas heat exchanger is just started, the heat exchange body 200 just starts to generate high-temperature flue gas, so that less condensed water is generated in the condensing box 100, and the temperature in the evaporation cavity 310 is slowly increased; when the temperature in the evaporation cavity 310 gradually rises to the first preset temperature value, the condensed water in the condensation box 100 continuously flows into the evaporation cavity 310, and when the water amount detection element 600 detects that the actual water amount in the evaporation cavity 310 is smaller than the third preset water amount, the control element can determine that the condensed water in the evaporation cavity 310 is too little, so as to avoid the overheating problem, and the control element controls the water replenishing assembly 500 to replenish water to the evaporation cavity 310.

It is understood that the third predetermined amount of water may be the minimum standard amount of water required to be in the evaporation chamber 310 when the temperature of the evaporation chamber 310 is the first predetermined temperature, that is, when the temperature of the evaporation chamber 310 is the first predetermined temperature, the overheating problem can be just avoided if the actual amount of water in the evaporation chamber 310 is the third predetermined amount of water. Of course, the third preset water amount and the first preset temperature value can be flexibly adjusted or designed according to actual use requirements, and are not limited, and only the condition that overheating cannot occur is met.

Thus, when the condensing gas heat exchanger is just started, the heat exchange body 200 just starts to generate high-temperature flue gas, so that less condensed water is generated in the condensing box 100, and the temperature in the evaporation cavity 310 is slowly increased; when the temperature in the evaporation cavity 310 gradually rises to the first preset temperature value, the condensed water in the condensation box 100 continuously flows into the evaporation cavity 310, and when the water amount detection element 600 detects that the actual water amount in the evaporation cavity 310 is greater than the fifth preset water amount and less than the second preset water amount, the control element can determine that the condensed water in the evaporation cavity 310 is too much, so as to avoid the problem of flowing backwards, and the control element controls the water removal assembly to remove water from the evaporation cavity 310.

It is understood that the fifth predetermined amount of water may be the highest standard amount of water required to be in the evaporation chamber 310 when the temperature of the evaporation chamber 310 is the first predetermined temperature, that is, when the temperature of the evaporation chamber 310 is the first predetermined temperature, if the actual amount of water in the evaporation chamber 310 is the fifth predetermined amount of water, the backflow problem can be just avoided. Of course, the fifth preset water amount can be flexibly adjusted or designed according to actual use requirements, and is not limited, and only the condition that backflow cannot occur is met.

Specifically, S130a, if the condensing gas heat exchanger is in a normal combustion state, and the temperature of the evaporation cavity 310 is a second preset temperature value, and the actual water amount is smaller than a fourth preset water amount, performing water supplementing treatment on the evaporation cavity 310, where the fourth preset water amount is greater than the third preset water amount and smaller than the first preset water amount, and the second preset temperature value is greater than the first preset temperature value. Thus, when the condensing gas heat exchange device is in a stable normal combustion state, the heat exchange main body 200 stably generates high-temperature flue gas, so that condensed water is continuously generated in the condensing box 100, and the temperature in the evaporation cavity 310 is increased quickly; when the temperature in the evaporation cavity 310 gradually rises to the second preset temperature value, the condensed water in the condensation box 100 continuously flows into the evaporation cavity 310, and when the water amount detection element 600 detects that the actual water amount in the evaporation cavity 310 is smaller than the fourth preset water amount, the control element can determine that the condensed water in the evaporation cavity 310 is too little, so as to avoid the overheating problem, and the control element controls the water replenishing assembly 500 to replenish water to the evaporation cavity 310.

It is understood that the fourth predetermined amount of water may be the minimum standard amount of water required to be in the evaporation chamber 310 when the temperature of the evaporation chamber 310 is the second predetermined temperature, that is, when the temperature of the evaporation chamber 310 is the second predetermined temperature, the overheating problem can be just avoided if the actual amount of water in the evaporation chamber 310 is the fourth predetermined amount of water. Of course, the fourth preset water amount and the second preset temperature value can be flexibly adjusted or designed according to actual use requirements, and are not limited, and only the condition that overheating cannot occur is met.

Specifically, S130b, if the condensing gas heat exchanger is in a normal combustion state, and the temperature of the evaporation cavity 310 is a second preset temperature value, and the actual water amount is greater than a sixth preset water amount, performing a water removal process on the evaporation cavity 310, where the sixth preset water amount is greater than the fifth preset water amount and less than the second preset water amount. Thus, when the condensing gas heat exchange device is in a stable normal combustion state, the heat exchange main body 200 stably generates high-temperature flue gas, so that condensed water is continuously generated in the condensing box 100, and the temperature in the evaporation cavity 310 is increased quickly; when the temperature in the evaporation cavity 310 gradually rises to the second preset temperature value, the condensed water in the condensation box 100 continuously flows into the evaporation cavity 310, and when the water amount detection element 600 detects that the actual water amount in the evaporation cavity 310 is greater than the sixth preset water amount, the control element can determine that the condensed water in the evaporation cavity 310 is too much, so as to avoid the problem of flowing backwards, and the control element controls the water removal assembly to remove water from the evaporation cavity 310.

It is understood that the sixth predetermined amount of water may be the highest standard amount of water required to be in the evaporation chamber 310 when the temperature of the evaporation chamber 310 is the second predetermined temperature, that is, when the temperature of the evaporation chamber 310 is the second predetermined temperature, if the actual amount of water in the evaporation chamber 310 is the sixth predetermined amount of water, the backflow problem can be just avoided. Of course, the sixth preset water amount can be flexibly adjusted or designed according to actual use requirements, and is not limited here, and only the condition that backflow cannot occur is met.

It should be noted that, the obtaining of the working condition of the condensing gas heat exchanger can be realized by detecting the temperature difference and the flow velocity between the water inlet end and the water outlet end of the whole condensing gas heat exchanger, and the obtaining is not repeated herein because the obtaining can be realized by the existing mode.

In the actual use process, the control element can not only independently judge whether to perform water supplementing treatment or water removing treatment according to the actual water amount of the condensed water, but also independently judge whether to perform water supplementing treatment or water removing treatment according to the temperature information of the evaporation cavity 310, and the control element can also comprehensively judge whether to perform water supplementing treatment or water removing treatment according to the temperature information of the evaporation cavity 310 and the actual water amount of the condensed water.

S112, if it is detected that the temperature of the evaporation cavity 310 is the third preset temperature and the third preset temperature is greater than the preset maximum standard temperature, it indicates that the temperature of the evaporation cavity 310 is too high due to too little condensed water in the evaporation cavity 310, that is, the evaporation cavity 310 is overheated, and then the evaporation cavity 310 is subjected to water supplementing treatment to supplement water, so that the temperature of the evaporation cavity 310 is reduced to the normal temperature.

S113, if it is detected that the temperature of the evaporation cavity 310 is the fourth preset temperature and the fourth preset temperature is lower than the preset minimum standard temperature, it indicates that the temperature of the evaporation cavity 310 is too low due to too much condensed water in the evaporation cavity 310, that is, the condensed water may flow backward at the smoke inlet 110, and then the evaporation cavity 310 is subjected to a water removal process to remove water, so that the condensed water is reduced to a normal water level.

It is understood that the preset maximum standard temperature refers to the maximum temperature that can be reached when the evaporation chamber 310 is not overheated; the predetermined minimum standard temperature is the minimum temperature that can be reached when the evaporation chamber 310 is not back-flowed. The third preset temperature can be flexibly adjusted or designed according to actual use needs, no limitation is made here, only the requirement that overheating cannot occur is met, the fourth preset temperature can be flexibly adjusted or designed according to the actual use needs, no limitation is made here, and only the requirement that backflow cannot occur is met.
