Description
Technical Field
The invention relates to a comprehensive exhaust sterilizing system and method for a high-pollution building space, and belongs to the field of indoor environment treatment.
Background
Viruses are extremely prone to long-term survival in wet and cold environments, especially in tight, air-tight underground spaces or above-ground spaces where the outer window cannot be opened. How to ventilate and ventilate the airtight building space and avoid secondary pollution caused by virus leakage becomes a difficult problem to be solved in the industry.
Such as underground trade halls in a wholesale market, become high risk areas after emergency evacuation of merchants infected with viruses, the space is airtight, a large amount of meat left behind is rotted and spoiled in high-temperature weather, the air composition is complex and the concentration is high, and the possibility of viruses and methane is not excluded. Meanwhile, because of worry about secondary pollution caused by virus leakage, the air conditioner and the exhaust system of the underground transaction hall are in a deactivated state, and people directly enter the underground transaction hall to kill the air conditioner and the exhaust system, so that the difficulty is high and the risk is high.
Studies have shown that viruses can be transmitted in aerosol form and have extremely high viability in humid low temperature environments.
In view of this, it is necessary to develop a comprehensive exhaust and disinfection system for highly polluted building spaces.

Through the technical scheme, the invention at least has the following beneficial effects:
1. The aeration principle is utilized to thoroughly kill viruses. The aeration principle in the water treatment engineering is applied to gas disinfection, the high-flow gas is subdivided into small bubbles by using a microporous aerator, the small bubbles are sent into the chlorine-containing disinfectant, the small bubbles are fully contacted with the chlorine-containing disinfectant, part of virus aerosol particles in the bubbles are absorbed by the chlorine-containing disinfectant, part of virus aerosol particles are combined with the disinfectant volatilized by the chlorine-containing disinfectant (simultaneously absorb part of VOC in the air flow), and the virus is disinfected after contacting the chlorine-containing disinfectant, so that the virus content in the air flow sent by a fan is obviously reduced, and better disinfection effect is realized compared with the prior disinfection air flow technology of the disinfectant. In addition, the chlorine-containing disinfectant is naturally volatilized in the space at the upper part in the aeration disinfection water tank, so that the volatilized chlorine-containing disinfectant is filled, and the air flow is combined with the volatilized chlorine-containing disinfectant in the space, so that a good disinfection effect can be achieved.
2. A wet film humidifying sterilizer containing chlorine disinfectant is arranged. The invention utilizes the principle that the wet film humidifier contacts the water-absorbing film with air, and the moisture on the film volatilizes and then is humidified. The working liquid of the wet film humidifier is changed into disinfectant from air, the disinfectant is volatilized on the wet film and then enters the air flow in the form of disinfectant steam, the particle size of the disinfectant steam is small, and compared with other disinfectant such as spray liquid drops and the like, the disinfectant steam with small particle size is easy to combine with aerosol in the air flow to effectively disinfect viruses.
3. A high-temperature electric heating section is arranged. Related studies have shown that viruses are difficult to survive in high temperature environments. The invention is provided with the high-temperature electric heating section, can heat the air flow, the surface temperature of the electric heating rod of the air flow electric heater in the high-temperature electric heating section can reach hundreds of ℃, viruses in the air flow in direct contact with the electric heating rod can be killed instantly, and the whole temperature of the air flow is heated to be more than 65 ℃. After the air flow is heated, the relative humidity is greatly reduced, and chlorine-containing disinfection liquid drops in the air flow are further volatilized and gasified at high temperature. The relative humidity of the air flow is greatly reduced, which is beneficial to the next filtering treatment. In addition, as the virus has obviously shortened survival time at the high temperature of more than 65 ℃, the risk of residual virus in the air flow is further reduced after the virus is heated by the high-temperature electric heating section.
4. A temperature layered flow guiding device is arranged. The lower low-temperature air flow enters the lower low-temperature air guide pipe and then flows out of the temperature layered flow guiding device from the upper part, and the upper high-temperature air flow passes through the upper high-temperature air guide pipe and then flows out of the temperature layered flow guiding device from the lower part, so that the upper and lower air flows enter a high-temperature water heating section for heating after the positions of the upper and lower air flows are replaced in the temperature layered flow guiding device, and the conditions that the temperature of the upper and lower air flows are layered and the temperature of the lower air flow is not up to the standard are avoided. In addition, after the air flow in the center of the air duct is blocked and compressed by the inclined sections of the upper high-temperature air guide pipe and the lower low-temperature air guide pipe, vortex is formed, and then the air enters a narrow central compressed air duct, the air speed is increased, the vortex is further aggravated, the air flow in the center of the air duct can be aggravated through the heat exchange between the wall surface of the air guide pipe and the upper high-temperature air guide pipe and the lower low-temperature air guide pipe, and the temperatures of the lower air flow, the upper air flow and the central air flow in the air duct are more approximate. And the heat exchange effect is better than the laminar flow effect when the airflow with vortex flows to the high-temperature water heating section. Due to the installation process problem, gaps are inevitably formed between the heating device and the square air pipe or between the ultraviolet lamp dense array and the square air pipe. Air is a fluid with certain viscosity, and has wall-attached airflow attached to the wall of the air duct at the contact position of the air duct wall, the wall-attached airflow has low flow speed and is easy to pass through gaps between the heating device and the wall of the square air duct or between the dense array of ultraviolet lamps and the wall of the square air duct. This allows the coanda airflow to easily pass from the slit into the next processing stage without passing through a heating device or dense array of ultraviolet lamps. This is unacceptable in systems handling high-risk viruses. The air flow on the wall of the lower part of the air channel is compressed by the section of the air channel through the lower low-temperature air guide pipe and then is led to the downstream high position, the air flow on the wall of the upper part of the air channel is compressed and accelerated through the upper high-temperature air guide pipe and then is led to the downstream low position, and the air flows on the wall of the two sides are blocked by the inclined sections of the upper high-temperature air guide pipe and the lower low-temperature air guide pipe and then enter the central compressed air channel after being compressed. Therefore, the coanda airflow on the four sides of the square air pipe is guided and compressed to form airflow without coanda airflow and then sent to the downstream, so that the condition that the coanda airflow passes through gaps between the heating device and the square air pipe or gaps between the ultraviolet lamp dense array and the square air pipe and is not effectively disinfected is avoided. Because the upper high-temperature air guide pipe, the lower low-temperature air guide pipe and the central compressed air duct are all provided with structures with suddenly reduced air pipe sections, air flows flowing through the upper high-temperature air guide pipe, the lower low-temperature air guide pipe and the central compressed air duct can be compressed and accelerated and then are ejected out from the minimum section at a high speed, and thus wall-attached air flows are eliminated. When high-speed air flow is sprayed to the high-temperature water heating sections where the coils are densely distributed, severe vortex is formed due to the blocking of the coils which are staggered, and the heat exchange effect is enhanced.
5. The invention is provided with the high-temperature water heating section and the temperature layering flow guiding device, which are matched, and is equivalent to effectively supplementing the high-temperature electric heating section, so that all airflows are ensured to be fully heated. Specifically, the high-temperature water heating section further heats the air flow from the high-temperature electric heating section, and the temperature of the air flow can be further increased to 75 ℃. The water inlet temperature of the high-temperature water heating section is 95 ℃, and the water outlet temperature is 85 ℃. When passing through the high-temperature water heating section, the surface area of the dense high-temperature water coil is large, the contact area with the air flow is large, the air flow is fully heated, the condition of uneven temperature in the air flow is avoided (for example, the cross section size of an air pipe is large, after electric heating, the condition that the air flow at the upper part exceeds 70 ℃ and the air flow at the lower part of the air pipe just reaches 70 ℃ possibly occurs), and the risk of residual viruses in the air flow is further reduced.
6. A dense array of ultraviolet lamps is provided. Ultraviolet lamp bars in the ultraviolet lamp dense array are arranged in a staggered mode, and dense ultraviolet sterilization is carried out on the passing airflow. And the ultraviolet lamp rod adopts a high-power lamp rod, has a certain heating capacity while the ultraviolet emission power is strong, and can continuously maintain or improve the temperature of the air flow. Ozone generated by ionizing air by the high-power ultraviolet lamp can further kill viruses in the air flow and is beneficial to decomposing harmful substances in the air flow.
7. Is provided with an airflow quality monitoring and sampling device and a high-efficiency variable-frequency fan. The rotating speed of the high-efficiency variable frequency fan can be adjusted by detecting the quality of the air flow passing through each treatment section, the treatment air quantity is changed, and whether the filter is replaced or not is determined. For example, when the air flow quality is not good through the air flow quality monitoring and sampling device, the rotating speed of the high-efficiency variable-frequency fan can be reduced, namely the processed air quantity is reduced, the air speed of the section of the air conditioner is reduced, and the air processing effect is improved. If the rotating speed is reduced, after the processing air quantity is reduced, the filter is replaced when the air quality is still poor through the air quality monitoring and sampling device; when the air flow quality is found to be far higher than the related index through the air flow quality monitoring and sampling device, the rotating speed of the high-efficiency variable-frequency fan can be improved, namely the processed air quantity is increased, and the processed air quantity in unit time is improved. If the rotating speed is reduced, after the air quantity is reduced, when the air quality is still good through the air quality monitoring and sampling device, the operation with high rotating speed and high air quantity can be maintained, and if the condition that the detected air quality is still poor occurs, the rotating speed and the air quantity of the fan are reduced.
The air flow quality monitoring and sampling device and the high-efficiency variable frequency fan are matched to operate, so that the air flow treatment effect is ensured, the treatment effect is not influenced by overlarge treatment air flow, the treatment air quantity can be increased appropriately, and the ventilation efficiency is improved; and whether the filter needs to be replaced or not can be scientifically determined, waste is not generated due to early replacement, and secondary pollution is not generated due to too late replacement.
8. The air quality monitoring device is arranged, the building space negative pressure monitoring device is arranged, the air quality and the negative pressure condition in the polluted building space can be monitored in real time, equipment in the system is adjusted, the negative pressure in the polluted building space is ensured, and the leakage of toxic and harmful gases is avoided.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the drawings and detailed description so that those skilled in the art can practice the present invention.
As shown in fig. 1, one embodiment of the high-pollution building space exhaust comprehensive disinfection system of the invention comprises an outdoor negative pressure metal ventilation pipe 9, wherein the inlet end of the outdoor negative pressure metal ventilation pipe is arranged in a polluted building space a, and the outlet end of the outdoor negative pressure metal ventilation pipe is connected to an extraction opening of an outdoor high-efficiency variable frequency fan 10; the high-efficiency variable frequency fan 10 is sealed in the square air pipe 30; the exhaust port of the high-efficiency variable frequency fan 10 is connected to the air inlet of the microporous aerator 12 in the chlorine-containing disinfectant aeration disinfection water tank 11, the microporous aerator 12 is provided with a plurality of air outlet microporous gases, the air flow discharged by each air outlet microporous enters the chlorine-containing disinfectant aeration disinfection water tank 11 as small bubbles, the small bubbles are fully contacted with the chlorine-containing disinfectant, at least one part of virus aerosol particles in the air bubbles is absorbed by the chlorine-containing disinfectant, the other parts are combined with the disinfectant volatilized by the chlorine-containing disinfectant, and part of Volatile Organic Compounds (VOC) in the air flow are absorbed, and the viruses are disinfected after contacting the chlorine-containing disinfectant, so that the virus content in the air flow sent out by the high-efficiency variable frequency fan 10 is remarkably reduced. In the space at the upper part of the inner part of the chlorine-containing disinfectant aeration disinfection water tank 11, the disinfectant is naturally volatilized, so that the volatilized chlorine-containing disinfectant is filled, and small bubbles burst when floating up to the space at the upper part of the inner part of the chlorine-containing disinfectant aeration disinfection water tank 11. The aerosol with virus remaining in the air flow is further contacted with volatile gas (namely disinfectant steam) of chlorine-containing disinfectant filled in the upper space, so that the virus in murderous look flows is further eliminated.
A building space negative pressure monitoring device 28 is arranged in the polluted building space A, and the building space negative pressure monitoring device 28 comprises a second controller and an air pressure sensor; the second controller is pre-stored with a preset air pressure, and is adapted to adjust the rotation speed of the high-efficiency variable frequency fan 10 according to the comparison result of the real-time detection value of the air pressure sensor and the preset air pressure value, so as to maintain the air pressure in the polluted building space A within the preset air pressure range. When the building space negative pressure monitoring device 28 monitors that the negative pressure in the polluted building space A does not reach the standard, namely, is higher than the preset air pressure value, the rotating speed of the efficient variable frequency fan 10 is increased, the air discharge quantity is increased, the negative pressure in the polluted building space A is maintained, and the air in the polluted building space A is prevented from leaking.
In one embodiment of the high pollution building space exhaust comprehensive disinfection system of the invention, the exhaust port of the chlorine-containing disinfectant aeration disinfection water tank 11 is connected to the chlorine-containing disinfectant wet film humidifying sterilizer 31, the chlorine-containing disinfectant wet film humidifying sterilizer 31 is connected to the humidifying pump 35, and the humidifying pump 35 enables chlorine-containing disinfectant to flow out from the upper part of the wet film humidifier of the chlorine-containing disinfectant wet film humidifying sterilizer 31, slowly flow down along the surface of the wet film to infiltrate the whole wet film; the wet film humidifying sterilizer 31 containing chlorine disinfectant is sealed in the square air pipe 30. When the air flow passes through the wet film, chlorine-containing disinfectant on the wet film is accelerated to volatilize and then enters the air flow, so that residual viruses in the air flow are killed. At the same time, some of the VOCs in the gas stream are absorbed by the chlorine-containing sterilizing fluid on the wet film. The humidification pump 35 is a small-flow variable-frequency pump with a pump body and blades made of plastic materials.
In one embodiment of the system for comprehensively sterilizing the exhaust air of the high-pollution building space, a high-temperature electric heating section 13 is arranged in the square air pipe 30 and is close to the chlorine-containing disinfectant wet film humidifying sterilizer 31, and an air flow electric heater is arranged in the high-temperature electric heating section 13 and is suitable for heating the air flow to be more than 65 ℃. After the airflow is heated, the relative humidity is greatly reduced. And at high temperature, the tiny droplets of chlorine-containing disinfectant in the airflow are further heated and gasified. In addition, the relative humidity of the air flow is greatly reduced, which is beneficial to the next filtering treatment. Meanwhile, as the survival time of the viruses is obviously shortened at the high temperature of more than 65 ℃, the risk of residual viruses in the air flow is further reduced after the viruses are heated by the high-temperature electric heating section 13. In addition, the surface temperature of the electric heating rod of the air flow electric heater in the high-temperature electric heating section 13 can reach hundreds of degrees centigrade, and the electric heating rod has instant disinfection function on viruses in air flow in direct contact with the electric heating rod.
In one embodiment of the system for comprehensively sterilizing the exhaust air of the high-pollution building space, the square air pipe 30 is provided with the high-temperature water heating sections 14 adjacent to the high-temperature electric heating sections 13, the high-temperature water heating sections 14 are internally provided with high-temperature water coils which are arranged in a staggered manner, and two ports of the high-temperature water coils are respectively communicated with two hot water pipes 24 to form a hot water circulation pipeline. The high-temperature water heating section 14 further heats the air flow from the high-temperature electric heating section 13, and the temperature of the air flow can be further raised to 75 ℃. The water inlet temperature of the high-temperature water heating section 14 can reach 95 ℃ and the water outlet temperature is 85 ℃. When the air flow passes through the high-temperature water heating section 14, the surface area of the dense high-temperature water coil is large, the contact area with the air flow is large, the air flow is sufficiently heated, the condition that the temperature in the air flow is uneven (for example, the cross section size of the square air pipe 30 is large, after electric heating, the condition that the air flow at the upper part of the square air pipe 30 exceeds 70 ℃ and the air flow at the lower part just reaches 70 ℃ can possibly occur) can be avoided, and the risk of residual viruses in the air flow is further reduced.
In one embodiment of the exhaust comprehensive disinfection system for high-pollution building space of the present invention, a temperature layering flow guiding device 32 is disposed in the square air pipe 30 between the high-temperature electric heating section 13 and the high-temperature water heating section 14. As shown in fig. 2-10, the arrows in the drawing indicate the flow direction of the air flow, and the temperature layered air guiding device 32 includes an upper layer high temperature air guiding pipe 32-1, a lower layer low temperature air guiding pipe 32-2 and a central compressed air duct 32-3; the lower low-temperature air flow flows out from the upper part after entering the lower low-temperature air guide pipe 32-2, and the upper high-temperature air flow flows out from the lower part after passing through the upper high-temperature air guide pipe 32-1, so that the upper and lower air flows enter the high-temperature water heating section 14 for heating after being displaced in the temperature layered flow guide device 32, and the condition that the temperature of the lower air flow does not reach the standard due to temperature layering in the air flow is avoided.
The air flow in the center of the air duct is blocked and compressed by the inclined sections 32-2-1 of the upper high-temperature air guide pipe 32-1 and the lower low-temperature air guide pipe 32-2 to form vortex, and then enters the narrow central compressed air duct 32-3, so that the air speed is increased, the vortex is further increased, the air flow in the center of the air duct can be increased, and the heat exchange between the air flow in the center of the air duct and the upper high-temperature air guide pipe 32-1 and the lower low-temperature air guide pipe 32-2 is enhanced through the wall surface of the air guide pipe, so that the temperatures of the lower air flow, the upper air flow and the central air flow in the air duct are more approximate. And, the heat exchange effect is better than the laminar flow effect when the airflow with vortex flows to the high-temperature water heating section 14.
In one embodiment of the exhaust comprehensive disinfection system for a high-pollution building space, an ultraviolet lamp dense array 15 is arranged in the square air pipe 30 and is close to the high-temperature water heating section 14, and the ultraviolet lamp dense array 15 comprises a plurality of ultraviolet lamp rods which are arranged in a staggered manner and are used for performing dense ultraviolet disinfection on air flow from the high-temperature water heating section 14. The ultraviolet lamp rod adopts a high-power lamp rod, has certain heating capacity while the ultraviolet emission power is strong, and can continuously maintain or improve the temperature of the air flow.
Due to the installation process problem, gaps are inevitably present between the heating devices in the high-temperature electric heating section 13 and the high-temperature water heating section 14 and the square air pipe 30 or between the ultraviolet lamp dense array 15 and the square air pipe 30. Air is a fluid with certain viscosity, and has wall-attached airflow attached to the wall surface at the position where the air contacts with the inner wall of the square air pipe 30, and the wall-attached airflow has low flow velocity and is easy to pass through gaps between the heating device and the square air pipe 30 or between the ultraviolet lamp dense array 15 and the square air pipe 30. This allows the coanda airflow to pass from the slot into the next processing stage without being processed by the heating device or the dense array of ultraviolet lamps 15. This is unacceptable in systems handling high-risk viruses. The air flow with the wall at the lower part of the air duct is compressed by the reduced section of the air duct through the lower low-temperature air duct 32-2 and then led to the downstream high position, the air flow with the wall at the upper part of the air duct is compressed and accelerated through the upper high-temperature air duct 32-1 and then led to the downstream low position, and the air flows with the wall at the two sides are blocked and compressed by the upper high-temperature air duct 32-1 and the inclined section 32-2-1 of the lower low-temperature air duct 32-2 and then enter the central compressed air duct 32-3. In this way, the wall-attached air flows of the four walls of the square air pipe 30 are all guided and compressed to form the air flow without the wall-attached air flow and then sent to the downstream, so that the condition that the wall-attached air flow passes through gaps between the heating device and the square air pipe 30 or gaps between the ultraviolet lamp dense array 15 and the square air pipe 30 and is not effectively disinfected is avoided.
Because the upper high temperature air guide pipe 32-1, the lower low temperature air guide pipe 32-2 and the central compressed air duct 32-3 have the structure that the air pipe cross sections are suddenly reduced, the air flow flowing through the upper high temperature air guide pipe 32-1, the lower low temperature air guide pipe 32-2 and the central compressed air duct 32-3 can be compressed and accelerated and then sprayed out from the minimum cross section at high speed, so that the coanda air flow is eliminated. When the high-speed air flow is sprayed to the high-temperature water heating section 14 of the densely distributed coil pipes, strong vortex is formed, and the heat exchange effect is enhanced. The temperature layering flow guiding device 32 eliminates the coanda airflow of the four walls of the square air pipe 30, and it is of great importance to avoid the coanda airflow and viruses possibly existing in the coanda airflow from entering the next section through gaps.
In one embodiment of the exhaust comprehensive disinfection system for the high-pollution building space, a middle-efficiency filtering section 17, a high-efficiency filtering section 18 and a spraying disinfection section 19 are sequentially arranged in the square air pipe 30 and are close to the ultraviolet lamp dense array 15; the medium-efficiency filtering section 17 is used for performing medium-efficiency filtering on the air flow disinfected by the ultraviolet lamp dense array 15, the high-efficiency filtering section 18 is used for performing high-efficiency filtering on the air flow subjected to medium-efficiency filtering in the medium-efficiency filtering section 17, and the spraying disinfection section 19 is used for spraying hydrogen peroxide to disinfect the air flow subjected to high-efficiency filtering in the high-efficiency filtering section 18. The hydrogen peroxide can be decomposed into water and oxygen, and the harm to the environment is small. The medium-efficiency filter in the medium-efficiency filter section 17 and the high-efficiency filter in the high-efficiency filter section 18 cannot be cleaned, and belong to disposable consumables. The other parts can be used repeatedly and repeatedly, and can be cleaned if necessary.

In one embodiment of the integrated system for sterilizing high pollution building space exhaust, an air flow quality monitoring and sampling device 27 is also arranged at each treatment section and is used for monitoring the quality of air flow after each treatment section. The device can monitor the temperature, humidity, speed, particulate matter content such as PM2.5, VOC content, chlorine-containing disinfectant content of air current in real time to sample the air every certain time. Where the VOC content may characterize the contaminant content in the air, the intermittent sampling is accomplished by a miniature air pump and multiple small sampling containers in the air flow quality monitoring and sampling device 27. At intervals, the small sampling container can be taken out of the air flow quality monitoring and sampling device 27 and sent to a laboratory for virus detection to determine whether residual viruses remain in the air flow. When the air flow quality monitoring and sampling device 27 monitors that the VOC content in the air flow exceeds the standard or the content of the chlorine-containing disinfectant is too low, it means that the air flow treatment is not enough at this time, and the high-efficiency variable frequency fan 10 needs to be adjusted to reduce the rotation speed, so as to reduce the air supply quantity, and further reduce the treatment air flow (treatment load) of the chlorine-containing disinfectant aeration disinfection water tank 11, the microporous aerator 12, the high-temperature electric heating section 13, the high-temperature water heating section 14 and the ultraviolet lamp dense array 15, so as to further improve the treatment effect. On the contrary, when various parameters are far better than the related indexes determined according to the prior art, the rotating speed of the high-efficiency variable frequency fan 10 is increased, so that the air supply quantity is increased, and the processing efficiency is improved.
The parameters obtained by the air flow quality monitoring and sampling device 27 are also important criteria for determining whether to replace the filter. When the air flow quality monitoring parameters after the middle-efficiency filter section 17 or the high-efficiency filter section 18 are not good (such as the VOC content is too high) or the virus residue is detected, the corresponding filter needs to be replaced as soon as possible.
If the parameters of the air flow quality monitoring and sampling device 27 reach standards and viruses are not detected after long-time and multiple-time monitoring, and the polluted building space A still needs to be continuously ventilated, the second high-tightness switching electromagnetic valve 16-2 of the first switching section 16, which is communicated with the air compressor 20, is opened, the first high-tightness switching electromagnetic valve 16-1 of the first switching section 16, which is communicated with the medium-efficiency filtering section 17, is closed, the air flow is directly discharged out of the room, and the medium-efficiency or high-efficiency filter loss is reduced. In the initial operating condition, the second high tightness switching solenoid valve 16-2 leading to the air compressor 20 is closed and the first high tightness switching solenoid valve 16-1 leading to the intermediate filter stage 17 is opened.
In one embodiment of the exhaust comprehensive disinfection system for the high-pollution building space, the air outlet end of the air compressor 20 is connected to the air inlet of the compressed air storage tank 21, the air outlet of the compressed air storage tank 21 is connected to the burner 22, the burner 22 is connected to the gas hot water boiler 23, the water inlet and the water outlet of the gas hot water boiler 23 are respectively communicated with two hot water pipes 24, one end of each hot water pipe 24 is connected to the high-temperature water heating section 14, and the other end is connected to the high-temperature decontamination water tank 25; the compressed air storage tank 21 is internally provided with a first flue gas waste heat coil pipe 33, the Gao Wenxi water-eliminating tank 25 is internally provided with a second flue gas waste heat coil pipe 34, a flue gas outlet of the gas hot water boiler 23 is communicated with the first flue gas waste heat coil pipe 33, and the first flue gas waste heat coil pipe 33 is communicated with the second flue gas waste heat coil pipe 34.
And the air compressor is used for completely collecting and compressing the air flow passing through the ultraviolet lamp dense array or spraying disinfection section, and does not directly exhaust any air to the atmosphere, so that the risk that viruses leak outdoors through aerosol in the air flow is greatly reduced again.
The air flow compressed and collected by the air compressor 20 is stored in a compressed air storage tank 21 for standby. The gas hot water boiler 23 may provide bath hot water for nearby hotels, dormitories or residents, and also provide decontamination water for the high temperature decontamination water tank 25, and provide heating circulation water for the high temperature water heating section 14. The gas hot water boiler 23 is provided with a burner 22, and the burner 22 does not directly take air from the atmosphere for combustion, but introduces compressed air from the compressed air storage tank 21 to mix with gas for combustion, and heats the gas hot water boiler 23. The compressed air in the compressed air storage tank 21 enters the burner 22 to be mixed with the fuel gas for combustion, oxygen in the compressed air is consumed, the temperature of the residual nitrogen and possibly residual toxic and harmful gas is instantaneously raised to 900-1100 ℃ in the hearth, viruses possibly contained in the extremely low probability become ash at the high temperature of the hearth and are unlikely to survive, and then the gas in the hearth forms flue gas of the fuel gas boiler to be discharged out of the boiler and enter the first flue gas waste heat coil 33. The first flue gas waste heat coil 33 exchanges heat with the compressed air in the compressed air storage tank 21, so that the temperature of the compressed air is increased, the survival probability of viruses in the compressed air storage tank 21 is further reduced, the temperature of the compressed air entering the combustor 22 is increased, the combustion efficiency of the combustor 22 is improved, the fuel gas consumption is saved, and the energy-saving and environment-friendly effects are achieved.
The second flue gas waste heat coil 34 is arranged in the high-temperature decontamination water tank 25, and the flue gas (the temperature can reach more than 100 ℃) after heat exchange by the first flue gas waste heat coil 33 is led into the second flue gas waste heat coil 34 in the high-temperature decontamination water tank 25 to exchange heat with the high-temperature water, so that the high-temperature water temperature in the high-temperature decontamination water tank 25 is maintained, the heat in the flue gas is further recovered, and the energy is saved and the environment is protected. When the system is in a non-use maintenance state, hot water in the high-temperature decontamination water tank 25 can be used for flushing and maintaining the chlorine-containing disinfection solution aeration decontamination water tank 11, the microporous aerator 12, the high-temperature electric heating section 13, the high-temperature water heating section 14, the ultraviolet lamp dense array 15, each high-tightness switching electromagnetic valve, the temperature layering flow guiding device 32 and the like, so that pollutant residues in each section are avoided.

The air compressor 20 and the combustor 22 need to comprehensively see the detection parameters of the air flow quality monitoring and sampling device 27 to determine whether to start, if the detection parameters of the air flow quality monitoring and sampling device 27 are not up to standard, the air flow in the pipeline needs to be continuously killed, and at this time, the air compressor 20 and the combustor 22 need to be kept in the starting operation so as to collect and consume the processed air flow, and the air flow is burned and killed. If the detected parameters of the air flow quality monitoring and sampling device 27 reach the standard, it indicates that the pollutants such as viruses in the air flow in the pipeline are completely killed, and the killing operation can be stopped, and at this time, the air compressor 20 and the burner 22 can be turned off.
