Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that all the directional indicators (such as up, down, left, right, front, and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the movement situation, etc. in a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly.
The main solution of the embodiment of the invention is as follows: acquiring environmental parameters of the incinerator during waste incineration; judging whether the environmental parameters meet preset reference standards or not; if so, controlling the monitoring equipment to keep a closed state, otherwise, controlling the monitoring equipment to be opened.
In the prior art, when the incinerator burns garbage, the monitoring equipment starts sampling at the same time so as to detect whether dioxin generated by the incineration of the garbage by the incinerator exceeds the standard or not. However, the monitoring device and the incinerator are operated synchronously, which undoubtedly causes the ineffective operation of the monitoring device and increases the monitoring cost.
The invention provides the solution, and aims to avoid the invalid operation of the monitoring equipment and reduce the monitoring cost.
The invention provides a control device of monitoring equipment, which is applied to control of the monitoring equipment.
In an embodiment of the present invention, referring to fig. 1, a control device of a monitoring apparatus includes: a processor 1001, such as CYU, a memory 1002 and a control program for a monitoring device stored on said memory 1002 and being executable on said processor 1001, said control program for a monitoring device realizing the steps of the method for controlling a monitoring device described below when executed by said processor 1001. The processor 1001 is connected to the memory 1002. The memory 1002 may be a high-speed RXM memory, or may be a non-volatile memory (non-volatile memory), such as a disk memory. The memory 1002 may alternatively be a storage device separate from the processor 1001. Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the device and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1002, which is a readable storage medium, includes a control program of the monitoring apparatus. In the device shown in fig. 1, the processor 1001 may be configured to call a control program of the monitoring device stored in the memory 1002 and perform operations of relevant steps of a control method of the monitoring device in the following embodiments.
As shown in fig. 2, the present invention further provides a method for controlling a monitoring device, including the following steps:
step S10, acquiring environmental parameters of the incinerator when the garbage is incinerated;
step S20, judging whether the environmental parameters meet the preset reference standard;
and step S30, if yes, controlling the monitoring equipment to keep a closed state, otherwise, controlling the monitoring equipment to be opened.
Because the generation amount of the dioxin during the waste incineration in the incinerator is related to the environmental parameters during the waste incineration in the incinerator, when the environmental parameters during the waste incineration in the incinerator meet the preset reference standard, the generation amount of the dioxin during the waste incineration in the incinerator does not cause the discharge amount of the dioxin to exceed the standard, and at the moment, monitoring equipment does not need to be started; and only when the environmental parameters in the incineration process of the garbage in the incinerator do not meet the preset reference standard, the generation amount of the dioxin in the incineration process of the garbage in the incinerator can cause the problem that the emission amount of the dioxin exceeds the standard, and at the moment, the monitoring equipment needs to be started to monitor the emission amount of the dioxin. Therefore, the technical scheme of the invention can more accurately know the starting time of the monitoring equipment by judging whether the environmental parameters meet the preset reference standard when the garbage is incinerated in the incinerator so as to start the monitoring equipment; and the monitoring equipment can be kept closed in other states, so that the invalid operation of the monitoring equipment is avoided, and the monitoring cost is reduced.
It should be noted that, because the content of dioxin generated by burning garbage in the incinerator is related to the environmental parameters of the incinerator, the environmental parameters of the incinerator can reflect the content of dioxin generated by burning garbage in the incinerator, that is, when the environmental parameters of the incinerator during burning garbage meet the preset reference standard, the amount of dioxin generated during burning garbage in the incinerator does not cause the discharge amount of dioxin to exceed the standard, and the monitoring device is controlled to be kept closed; environmental parameters when the waste in the incinerator is incinerated do not meet the preset reference standard, the problem that the discharge amount of the dioxin exceeds the standard is possibly caused by the generation amount of the dioxin during the waste incineration in the incinerator, and the monitoring device is controlled to be started. For example, when the preset reference standard of the incineration temperature in the incinerator is greater than 900 ℃ and the preset reference standard of the incineration time in the incinerator is greater than 4 hours, under the condition that the incineration temperature is greater than 900 ℃ and greater than 4 hours, the garbage in the incinerator is fully combusted, and the content of dioxin generated by the incinerator is very low and can be ignored. When the obtained furnace burning temperature is 1000 ℃ and the furnace burning time is 5 hours, the 1000 ℃ is more than 900 ℃, the 5 hours is less than 4 hours, the obtained furnace burning temperature meets the furnace temperature of a preset reference standard, and the obtained furnace burning time meets the time of the preset reference standard, so that the obtained result is defined as a, and a is a first result; when the obtained furnace burning temperature is 800 ℃ and the furnace burning time is 3 hours, the 800 ℃ is less than 900 ℃, the 3 hours is less than 4 hours, the obtained furnace burning temperature is less than the furnace temperature of the preset reference standard, and the obtained furnace burning time is less than the time of the preset reference standard, therefore, the obtained result a is the second result, of course, the first result can be assigned to 0, the second result can be assigned to 1, and then whether the monitoring equipment is opened or kept closed is controlled according to whether the assignment of a is 0 or 1.
Correspondingly, the environmental parameters further include furnace air flow, boiler outlet smoke temperature, smoke residence time, quencher operating parameters, dust remover outlet temperature, dust remover pressure drop, adsorber operating parameters and conventional pollutant concentration, the result of the furnace air flow is defined as b, the result of the boiler outlet smoke temperature is c, the result of the smoke residence time is d, the result of the quencher operating parameters is defined as e, the results of the dust remover outlet temperature and dust remover pressure drop are defined as g, the result of the adsorber operating parameters is defined as h, and the result of the conventional pollutant concentration is defined as f, so that an expression of the starting parameter (K) of the monitoring equipment can be obtained: k is a + b + c + d + e + g + h + f, the first result of reducing the amount of dioxin emission is assigned to 0, and the second result of causing an increase in the amount of dioxin emission is assigned to 1. That is, when the air flow in the boiler, the smoke temperature at the outlet of the boiler, the residence time of the smoke, the operation parameters of the quencher, the outlet temperature of the dust remover, the pressure drop of the dust remover, the operation parameters of the adsorber and the concentration of the conventional pollutants respectively meet the preset reference standards, a, b, c, d, e, g, h and f all obtain a first result with the value of 0; on the contrary, when the air flow in the boiler, the smoke temperature at the outlet of the boiler, the retention time of the smoke, the operation parameter of the quencher, the outlet temperature of the dust remover, the pressure drop of the dust remover, the operation parameter of the adsorber and the concentration of the conventional pollutants respectively do not meet the preset reference standard, a, b, c, d, e, g, h and f all obtain a second result with the value of 1; therefore, the starting parameters can be calculated according to the first result and the second result, whether the monitoring equipment needs to be controlled to start or not can be judged by judging whether K is greater than or equal to 1, and obviously, when K is greater than or equal to 1 and the value of K is larger, more dioxin is generated, and the monitoring equipment needs to be started to monitor the content of the dioxin; on the contrary, when K is less than 1, all the factors are to reduce the emission amount of dioxin, and the content of the dioxin can be ignored at the moment, so that standard exceeding emission can not be caused, and monitoring equipment is not required to be started to monitor the dioxin. Therefore, the starting of the monitoring equipment is controlled by judging whether the starting parameter of the monitoring equipment is more than or equal to 1.
As shown in fig. 3, based on the first embodiment, the present invention further provides a second embodiment of a control method for a monitoring device. In a second embodiment, the environmental parameters include boiler plant operating condition parameters, purification plant operating condition parameters, and contaminant concentrations; the step of judging whether the environmental parameter meets the preset reference standard comprises the following steps:
step S21, judging whether the working condition parameters of the boiler equipment meet a first preset standard in the preset reference standards; step S22, judging whether the working condition parameters of the purifying equipment meet a second preset standard in the preset reference standards; step S23, judging whether the concentration of the pollutant meets a third preset standard in the preset reference standard; and if the results of the three judgments are all satisfied, determining that the environmental parameter satisfies a preset reference standard, otherwise determining that the environmental parameter does not satisfy the preset reference standard.
It should be noted that, a start parameter K of the monitoring device is M + N + f, where K represents a start parameter of the monitoring device, M represents a result of a working condition parameter of the boiler device, N represents a result of a working condition parameter of the purifying device, and f represents a result of a concentration of a conventional pollutant, and when the working condition parameter of the boiler device meets a first preset standard in the preset reference standard, the value of M is 0, otherwise, the value of M is greater than or equal to 1; when the working condition parameters of the purifying equipment meet a second preset standard in the preset reference standards, the value of N is 0, otherwise, the value of N is more than or equal to 1; when the concentration of the conventional pollutants meets a third preset standard in the preset reference standard, the value of f is 0, otherwise, the value of f is more than or equal to 1; thus, when the three are satisfied, a first result with a value of 0 is obtained; otherwise, a second result with the value being more than or equal to 1 is obtained, and therefore effective control over the monitoring equipment can be achieved according to whether the obtained result is the first result or the second result.
Further, based on the second embodiment, the present invention provides a fourth embodiment of a method for controlling a monitoring device. In a fourth embodiment, the contaminants include hydrogen chloride, sulfur dioxide, carbon dioxide, and particulates; the step of determining whether the concentration of the pollutant meets a third preset standard in the preset reference standard further comprises:
and calculating the concentration of the pollutant according to the concentration of the hydrogen chloride, the concentration of the sulfur dioxide, the concentration of the carbon dioxide and the concentration of the particulate matters.
It should be noted that the presence of sulfur dioxide in flue gas generated by incineration of refuse can suppress the generation of dioxin, which accompanies SO2The concentration increases and the content of dioxin decreases. However, the presence of hydrogen chloride, carbon dioxide and particulates leads to the generation of dioxin, and the content of dioxin increases as the content thereof increases. Thus, embodiments of the present invention provide a method for calculating the concentration of a contaminant by establishing: x is 0.5 × Δ dust +0.4 × Δ HCl +0.3 × Δ CO2-0.2×ΔSO2) Wherein Δ dust represents the increase in particulate matter, Δ HCl represents the increase in hydrogen chloride, and Δ CO2Denotes the carbon dioxide increase,. DELTA.SO2The sulfur dioxide increase is expressed, and the above increases are calculated in the following manner, respectively.
When the content of dioxin in flue gas generated by waste incineration is very low, the value of x is less than 0, and the obtained result f is 0; when the content of dioxin in flue gas generated by waste incineration is high, the value of x is more than 0, and the obtained result f is 1. And then, the result f is substituted into a calculation formula of the starting parameter of the monitoring device, so that the monitoring device is controlled to be started or kept to be closed.
As shown in fig. 4, further, based on the second embodiment, the present invention provides a fifth embodiment of a control method of a monitoring apparatus. In a fifth embodiment, the boiler equipment working condition parameters comprise boiler body operation parameters and chiller operation parameters;
the step of judging whether the working condition parameters of the boiler equipment meet a first preset standard in the preset reference standards comprises the following steps of:
step S211, determining whether the boiler body operation parameters meet the boiler body operation standards in the first preset standard, step S213, and determining whether the chiller operation parameters meet the chiller operation standards in the first preset standard;
and if the two judgment results are both satisfied, determining that the working condition parameters of the boiler equipment satisfy a first preset standard in the preset reference standards, otherwise determining that the working condition parameters of the boiler equipment do not satisfy the first preset standard in the preset reference standards.
In addition, M is Y + e, Y represents the result of the boiler body operation parameters, and e represents the result of the chiller operation parameters.

Because the generation amount of the dioxin during the waste incineration in the incinerator is related to the environmental parameters during the waste incineration in the incinerator, when the environmental parameters during the waste incineration in the incinerator meet the preset reference standard, the generation amount of the dioxin during the waste incineration in the incinerator does not cause the discharge amount of the dioxin to exceed the standard, and at the moment, monitoring equipment does not need to be started; and only when the environmental parameters in the incineration process of the garbage in the incinerator do not meet the preset reference standard, the problem that the discharge amount of the dioxin exceeds the standard can be caused only by the generation amount of the dioxin in the incineration process of the garbage in the incinerator, and at the moment, the monitoring equipment needs to be started to monitor the discharge amount of the dioxin in real time.
