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 airflow in the form of disinfectant steam, the particle size of the disinfectant steam is small, and compared with the mode that other disinfectants such as spray liquid drops kill the airflow, the disinfectant steam with small particle size is easy to combine with aerosol in the airflow to effectively kill viruses.
3. Is provided with a high-temperature electric heating section. Related studies indicate that viruses are difficult to survive in high temperature environments. The invention is provided with a high-temperature electric heating section which can heat the air flow, the temperature of the surface of an 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 directly contacted with the high-temperature electric heating section can be killed instantly, and the integral 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 the chlorine-containing disinfection liquid drops in the air flow are further volatilized and gasified at high temperature. The relative humidity of the airflow is greatly reduced, so that the subsequent filtration treatment is facilitated. In addition, because the survival time of the virus is obviously shortened at the high temperature of more than 65 ℃, the risk of the virus remaining in the airflow is further reduced after the virus is heated by the high-temperature electric heating section.
4. A temperature layering flow guide device is arranged. The lower-layer low-temperature airflow enters the lower-layer low-temperature air guide pipe and then flows out of the temperature layering flow guide device from the upper part, and the upper-layer high-temperature airflow passes through the upper-layer high-temperature air guide pipe and then flows out of the temperature layering flow guide device from the lower part, so that the upper-layer airflow and the lower-layer airflow enter the high-temperature water heating section for heating after the upper-layer airflow and the lower-layer airflow are internally replaced and transposed in the temperature layering flow guide device, and the condition that the temperature of. In addition, the air current at wind channel center receives the separation of the slant section of upper high temperature guide duct and lower floor's low temperature guide duct, after the compression, form the vortex, later get into narrow and small central compression wind channel, the wind speed improves, further aggravate the vortex, the vortex of air current can aggravate the air current at wind channel center and pass through the heat transfer of guide duct wall and upper high temperature guide duct and lower floor's low temperature guide duct for the air current of lower floor in the wind channel, the temperature of upper air current and central air current is closer. And, the heat transfer effect is better when the air current that has the vortex flows to high temperature water heating section than the laminar flow effect. Due to the problem of the installation process, gaps can not be avoided between the heating device and the square air pipe or between the ultraviolet lamp dense array and the square air pipe. The air is a fluid and has certain viscosity, and the air has wall attaching airflow attached to the wall surface of the air pipe at the position contacted with the wall surface of the air pipe, and the wall attaching airflow has low flow rate and is easy to pass through a gap between the heating device and the wall surface of the square air pipe or between the ultraviolet lamp dense array and the wall surface of the square air pipe. This allows the coanda airflow to readily pass from the slot to the next process section without passing through a heating device or a dense array of ultraviolet lamps. This is unacceptable in systems that handle high risk viruses. The lower part of the air duct is compressed by the lower layer low-temperature air guide pipe through the reduction of the section of the air duct and then guided to the high position of the lower reaches, the upper part of the air duct is compressed and accelerated by the upper layer high-temperature air guide pipe and then guided to the low position of the lower reaches, and the wall-attached air flows at two sides enter the central compression air duct after being blocked and compressed by the inclined sections of the upper layer high-temperature air guide pipe and the lower layer low-temperature air guide pipe. Therefore, the wall attaching air flows on the four sides of the square air pipe are guided and compressed to form air flows without the wall attaching air flows and then are sent to the downstream, and the condition that the wall attaching air flows 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 are not effectively disinfected is avoided. Because the upper-layer high-temperature air guide pipe, the lower-layer low-temperature air guide pipe and the central compression air channel are all provided with the structure that the cross sections of the air pipes are suddenly reduced, the air flow flowing through the upper-layer high-temperature air guide pipe, the lower-layer low-temperature air guide pipe and the central compression air channel can be compressed and accelerated and then is sprayed out at a high speed from the minimum cross section, and therefore the wall attachment air flow is eliminated. When the high-speed airflow is sprayed to the high-temperature water heating section of the densely distributed coil pipes, serious eddy can be formed due to the obstruction of the coil pipes in staggered arrangement, and the heat exchange effect is enhanced.
5. The high-temperature water heating section is matched with the temperature layering flow guide device to effectively supplement the high-temperature electric heating section, so that all air flows are fully heated. Specifically, the high-temperature water heating section further heats the airflow from the high-temperature electric heating section, and the temperature of the airflow 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 the high-temperature water heating section is passed through, the surface area of the dense high-temperature water coil pipe is very large, the area contacted with the air flow is large, the air flow is sufficiently heated, the condition that the temperature in the air flow is uneven is avoided (for example, the size of the section of the air pipe is very large, after the air pipe is electrically heated, 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 ℃) is avoided, and the risk of residual viruses in the air flow is further reduced.
6. And a dense array of ultraviolet lamps is arranged. Ultraviolet lamp bars in the ultraviolet lamp dense array are arranged in a staggered mode, and dense ultraviolet rays are eliminated and killed in passing air flow. 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. The ozone generated by the high-power ultraviolet lamp ionizing the air can further kill viruses in the air flow and is beneficial to decomposing harmful substances in the air flow.
7. The device 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 found to be poor 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 volume is reduced, the air speed of the cross section of the air flow processing device is reduced, and the air processing effect is improved. If the rotating speed is reduced and the processing air volume is reduced, the filter is replaced when the air quality is still poor through the air flow quality monitoring and sampling device; when the airflow quality is found to be far higher than relevant indexes through the airflow quality monitoring and sampling device, the rotating speed of the high-efficiency variable-frequency fan can be increased, namely, the processed air volume is increased, and the processed air volume in unit time is increased. If the rotating speed is reduced, after the air volume is reduced, when the air quality is still good through the air flow quality monitoring and sampling device, the operation with high rotating speed and high air volume can be maintained, and if the condition that the detected air quality is still poor, the rotating speed and the air volume 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 volume can be increased at a proper time, and the ventilation efficiency is improved; and whether the filter needs to be replaced can be scientifically determined, waste is not caused by early replacement, and secondary pollution is not caused by late replacement.
8. The system is provided with an air quality monitoring device and a building space negative pressure monitoring device, so that 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 toxic and harmful gases are prevented from leaking.

Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can practice the invention.
As shown in fig. 1, one embodiment of the comprehensive air exhaust sterilizing system for a highly polluted building space of the present invention comprises an outdoor negative pressure metal ventilation pipe 9, an inlet end of which is arranged in a polluted building space a, and an outlet end of which is connected to an air exhaust 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; an air outlet of the high-efficiency variable frequency fan 10 is connected to an air inlet of a microporous aerator 12 in a chlorine-containing disinfectant aeration disinfecting and killing water tank 11, the microporous aerator 12 is provided with a plurality of air outlet microporous gases, air flow discharged from each air outlet microporous forms small bubbles to enter the chlorine-containing disinfectant aeration disinfecting and killing water tank 11, the small bubbles are fully contacted with the chlorine-containing disinfectant, at least one part of virus aerosol particles in the bubbles is absorbed by the chlorine-containing disinfectant, other parts of the virus aerosol particles are combined with the disinfectant volatilized by the chlorine-containing disinfectant, meanwhile, part of Volatile Organic Compounds (VOC) in the air flow are absorbed, and viruses are killed after contacting the chlorine-containing disinfectant, so that the virus content in the air flow sent by the high-efficiency variable frequency fan 10 is obviously. In the space at the upper part in the water tank 11 for disinfecting and aerating the chlorine-containing disinfectant, the volatilized chlorine-containing disinfectant is filled because the disinfectant naturally volatilizes, and small bubbles burst when floating to the space at the upper part in the water tank 11 for disinfecting and aerating the chlorine-containing disinfectant. The aerosol with virus in the air flow further contacts with the volatile gas (i.e. disinfectant vapor) of the chlorine-containing disinfectant filled in the upper space, and further kills the virus in the air flow.
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 a gas 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 between 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, that is, is higher than the preset air pressure value, the rotating speed of the high-efficiency variable-frequency fan 10 is increased, the air discharge amount 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 an embodiment of the comprehensive air-exhausting disinfecting and killing system for the highly polluted building space, the air outlet of the chlorine-containing disinfectant aeration disinfecting and killing 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, the humidifying pump 35 makes the chlorine-containing disinfectant flow out of the upper part of the wet film humidifier of the chlorine-containing disinfectant wet film humidifying sterilizer 31 and slowly flow down along the surface of the wet film to infiltrate the whole wet film; the wet film humidifying disinfector 31 of the chlorine-containing disinfectant is sealed in the square air pipe 30. When the air flow passes through the wet film, the chlorine-containing disinfection liquid on the wet film is accelerated to volatilize and then enters the air flow to kill residual viruses in the air flow. Meanwhile, part of VOC in the air flow is absorbed by the chlorine-containing disinfection solution on the wet film. The humidifying pump 35 can be a small flow variable frequency pump with a pump body and blades made of plastic materials.
In an embodiment of the comprehensive air exhaust disinfecting and killing system for the highly polluted building space, a high-temperature electric heating section 13 is arranged in the square air pipe 30 and is close to the humidifying and disinfecting device 31 for the wet film of the chlorine-containing disinfectant, and an airflow electric heater is arranged in the high-temperature electric heating section 13 and is suitable for heating airflow to be higher than 65 ℃. After the airflow is heated, the relative humidity is greatly reduced. And at high temperature, the tiny droplets of the chlorine-containing disinfection solution in the air flow are further heated and gasified. In addition, the relative humidity of the airflow is greatly reduced, so that the next filtering treatment is facilitated. Meanwhile, because the survival time of the virus is obviously shortened at the high temperature of more than 65 ℃, the risk of virus remaining in the air flow is further reduced after the virus is heated by the high-temperature electric heating section 13. Moreover, the surface temperature of the electric heating rod of the airflow electric heater in the high-temperature electric heating section 13 can reach hundreds of degrees centigrade, and the electric heating rod has instant disinfection and killing effects on viruses in the airflow directly contacting with the electric heating rod.
In an embodiment of the comprehensive air exhaust disinfecting and killing system for the high-pollution building space of the present invention, a high-temperature water heating section 14 is disposed in the square air duct 30 and is adjacent to the high-temperature electric heating section 13, high-temperature water coils are disposed in the high-temperature water heating section 14 and are arranged in a staggered manner, and two ports of the high-temperature water coils are respectively communicated to two hot water pipes 24 to form a hot water circulation pipeline. The high temperature water heating section 14 further heats the airflow from the high temperature electric heating section 13, and can further raise the temperature of the airflow 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 current passes through the high-temperature water heating section 14, the surface area of the dense high-temperature water coil pipe is large, the area contacting with the air current is large, the air current is sufficiently heated, the condition that the temperature in the air current is uneven can be avoided (for example, the section size of the square air pipe 30 is large, after the square air pipe is electrically heated, the condition that the air current at the upper part of the square air pipe 30 exceeds 70 ℃ and the air current at the lower part just reaches 70 ℃) can be avoided, and the risk of residual viruses in the air current is further reduced.
In an embodiment of the comprehensive air exhaust disinfecting and killing system for the highly polluted building space, a temperature layering flow guide device 32 is arranged in the square air pipe 30 and between the high-temperature electric heating section 13 and the high-temperature water heating section 14. As shown in fig. 2-10, arrows indicate the flowing direction of the air flow, and the temperature stratification 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-layer low-temperature airflow flows out from the upper part after entering the lower-layer low-temperature air guide pipe 32-2, and the upper-layer high-temperature airflow flows out from the lower part after passing through the upper-layer high-temperature air guide pipe 32-1, so that the upper-layer airflow and the lower-layer airflow enter the high-temperature water heating section 14 for heating after the upper-layer airflow and the lower-layer airflow are internally replaced in the temperature layering flow guide device 32, and the condition that the temperature of the lower-layer airflow does not reach the standard due to temperature.
The air flow in the center of the air channel is separated 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 a vortex, then the vortex enters the narrow central compressed air channel 32-3, the air speed is increased, the vortex is further intensified, the vortex can intensify the heat exchange of the air flow in the center of the air channel with the upper high-temperature air guide pipe 32-1 and the lower low-temperature air guide pipe 32-2 through the wall surfaces of the air guide pipes, and the temperatures of the lower air flow, the upper air flow and the central air flow in the air channel are closer. And, the heat exchange effect is better when the air current with the vortex flows to the high temperature water heating section 14 than the laminar flow effect.
In an embodiment of the comprehensive air exhaust killing system for the high-pollution building space of the present invention, an ultraviolet lamp dense array 15 is disposed in the square air duct 30 and adjacent to the high-temperature water heating section 14, and the ultraviolet lamp dense array 15 includes a plurality of ultraviolet lamp rods arranged in a staggered manner, and is configured to perform dense ultraviolet killing on the air flow from the high-temperature water heating section 14. The ultraviolet lamp rod adopts a high-power lamp rod, has high ultraviolet emission power and certain heating capacity, and can continuously maintain or improve the temperature of the air flow.
Due to the installation process problem, gaps inevitably exist between the heating devices in the high-temperature electric heating section 13 and the high-temperature water heating section 14 and the square air duct 30, or between the ultraviolet lamp dense array 15 and the square air duct 30. The air is a fluid and has certain viscosity, and the air has wall-attached airflow attached to the wall surface at the position contacted with the inner wall of the square air duct 30, so that the wall-attached airflow has low flow rate and is easy to pass through a gap between the heating device and the square air duct 30 or between the ultraviolet lamp dense array 15 and the square air duct 30. This allows the coanda airflow to be readily passed from the slot to the next treatment section without passing through a heating device or a dense array of ultraviolet lamps 15. This is unacceptable in systems that handle high risk viruses. Wall attaching airflow at the lower part of the air duct is compressed by the reduced section of the air duct and then guided to a high position at the lower part through the lower-layer low-temperature air guide pipe 32-2, wall attaching airflow at the upper part of the air duct is compressed and accelerated by the upper-layer high-temperature air guide pipe 32-1 and then guided to a low position at the lower part, and wall attaching airflow at two sides enters the central compressed air duct 32-3 after being blocked and compressed by the upper-layer high-temperature air guide pipe 32-1 and the inclined section 32-2-1 of the lower-layer low-temperature air guide pipe 32-2. In this way, the coanda airflow of the four walls of the square air duct 30 is guided and compressed to form airflow without coanda airflow and then sent to downstream, so that the condition that the coanda airflow passes through the gap between the heating device and the square air duct 30 or the gap between the ultraviolet lamp dense array 15 and the square air duct 30 and is not effectively sterilized is avoided.
Because the upper-layer high-temperature air guide pipe 32-1, the lower-layer low-temperature air guide pipe 32-2 and the central compressed air duct 32-3 are all provided with the structure that the cross sections of the air ducts are suddenly reduced, the air flow passing through the upper-layer high-temperature air guide pipe 32-1, the lower-layer low-temperature air guide pipe 32-2 and the central compressed air duct 32-3 can be compressed and accelerated and then is ejected out from the minimum cross section at a high speed, and therefore wall-attached air flow is eliminated. When the high-speed airflow is sprayed to the high-temperature water heating section 14 of the densely-distributed coil pipe, a strong vortex is formed, and the heat exchange effect is enhanced. The temperature stratification guide device 32 eliminates the coanda airflow of all four walls of the square duct 30, and has great significance in preventing the coanda airflow and viruses possibly existing in the coanda airflow from entering the next section through gaps.
In an embodiment of the comprehensive air exhaust disinfecting and killing system for the high-pollution building space, a middle-effect filtering section 17, a high-effect filtering section 18 and a spraying disinfecting and killing section 19 are sequentially arranged in the square air duct 30 and are close to the ultraviolet lamp dense array 15; the middle-effect filtering section 17 is used for performing middle-effect filtering on the air flow disinfected by the ultraviolet lamp dense array 15, the high-effect filtering section 18 is used for performing high-effect filtering on the air flow disinfected by the middle-effect filtering section 17, and the spraying sterilizing section 19 is used for spraying hydrogen peroxide to sterilize the air flow disinfected by the high-effect filtering section 18. The hydrogen peroxide can be decomposed into water and oxygen, and the harm to the environment is small. The medium-effect filter in the medium-effect filtering section 17 and the high-effect filter in the high-effect filtering section 18 cannot be cleaned, and the high-effect filtering section belongs to disposable consumables. Other parts can be repeatedly used for many times and cleaned when necessary.
In an embodiment of the comprehensive air exhaust sterilizing and killing system for the highly polluted building space, a first switching section 16 is connected between the intensive ultraviolet lamp array 15 and the intermediate-efficiency filter section 17, and the switching section comprises a first high-tightness switching electromagnetic valve 16-1 and a second high-tightness switching electromagnetic valve 16-2, wherein the first high-tightness switching electromagnetic valve 16-1 is arranged in the square air duct 30 and is suitable for closing or opening an air flow passage in the square air duct 30, and the second high-tightness switching electromagnetic valve 16-2 is arranged on the outer wall of the square air duct 30 and is suitable for exhausting air flow in the square air duct 30.
In an embodiment of the comprehensive air exhaust killing system for the highly polluted building space of the present invention, a second switching section 36 is connected to the spraying killing section 19, the second switching section 36 includes a third high-tightness switching solenoid valve 36-1 and a fourth high-tightness switching solenoid valve 36-2, wherein the third high-tightness switching solenoid valve 36-1 is disposed in the square duct 30 and connected to the air inlet end of the air compressor 20, and is adapted to close or open the passage from the air flow in the square duct 30 to the air compressor 20, and the fourth high-tightness switching solenoid valve 36-2 is disposed on the outer wall of the square duct 30 and is adapted to exhaust the air flow in the square duct 30; the second high-airtightness switching solenoid valve 16-2 is connected to the intake end of the air compressor 20.
In an embodiment of the comprehensive air exhaust disinfecting and killing system for the highly polluted building space, an air flow quality monitoring and sampling device 27 is further arranged at each processing section and is used for monitoring the quality of air flow passing through each processing section. The device can monitor the temperature, the humidity, the speed of the air current, the content of particulate matters such as PM2.5, the content of VOC and the content of chlorine-containing disinfectant in real time, and samples the air at certain intervals. The VOC content can represent the pollutant content in the air, and the interval sampling is completed by a miniature air pump and a plurality of miniature sampling containers in the air flow quality monitoring and sampling device 27. At intervals, the small sampling container can be taken out of the airflow quality monitoring and sampling device 27 and sent to a laboratory for virus detection to judge whether residual viruses still exist in the airflow. When the air flow quality monitoring and sampling device 27 monitors that the content of VOC in the air flow exceeds the standard or the content of the chlorine-containing disinfectant is too low, it indicates that the degree of air flow treatment is not sufficient, and the high-efficiency variable frequency fan 10 needs to be adjusted to reduce the rotation speed, so as to reduce the air supply volume, and further reduce the treatment air flow (treatment load) of the chlorine-containing disinfectant aeration sterilizing water tank 11, the micro-pore aerator 12, the high-temperature electric heating section 13, the high-temperature water heating section 14 and the ultraviolet lamp dense array 15, and further improve the treatment effect. On the contrary, when various parameters are far superior to relevant 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 amount is increased, and the treatment efficiency is improved.
The parameters obtained by the gas 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 (such as the VOC content is too high) or virus residues are detected after the middle-effect filtering section 17 or the high-effect filtering section 18 are not good, the corresponding filter needs to be replaced as soon as possible.
If the parameters of the airflow quality monitoring and sampling device 27 reach the standard after long-time and multiple monitoring, and no virus is detected, and the polluted building space A still needs to be ventilated, the second high-tightness switching electromagnetic valve 16-2 leading to the air compressor 20 of the first switching section 16 is opened, the first high-tightness switching electromagnetic valve 16-1 leading to the medium-efficiency filtering section 17 in the first switching section 16 is closed, and the airflow is directly discharged outdoors, so that 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 middle-effect filtering section 17 is opened.
In an embodiment of the comprehensive air exhaust and killing system for the highly polluted building space, an air outlet end of the air compressor 20 is connected to an air inlet of a compressed air storage tank 21, an air outlet of the compressed air storage tank 21 is connected to a burner 22, the burner 22 is connected to a gas hot water boiler 23, a water inlet and a water outlet of the gas hot water boiler 23 are respectively communicated to two hot water pipes 24, one end of each of the two hot water pipes 24 is connected to the high-temperature water heating section 14, and the other end of each of the two hot water pipes is connected to a 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 high-temperature decontamination water tank 25 is internally provided with a second flue gas waste heat coil pipe 34, a flue gas outlet of the gas-fired hot water boiler 23 is communicated to the first flue gas waste heat coil pipe 33, and the first flue gas waste heat coil pipe 33 is communicated to the second flue gas waste heat coil pipe 34.
The air compressor completely collects and compresses the air flow passing through the ultraviolet lamp dense array or the spraying disinfection section, and does not directly discharge any gas to the atmosphere, so that the danger that viruses are leaked to the outdoor through aerosol in the air flow is greatly reduced again.
The air flow collected by compression of the air compressor 20 is stored in the compressed air storage tank 21 for standby. The gas-fired hot water boiler 23 may provide bath hot water for a nearby hotel, dormitory or resident, and also provide the high-temperature decontamination water tank 25 with decontamination water and heating circulating water for the high-temperature water heating section 14. The gas-fired 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 and then burns, thereby heating the gas-fired hot water boiler 23. The compressed air in the compressed air storage tank 21 enters the combustor 22 to be mixed with the fuel gas and then combusted, the oxygen in the compressed air is consumed, the temperature of the residual nitrogen and the possible residual toxic and harmful gas is instantly raised to 900-1100 ℃ in the hearth, wherein the virus possibly contained with extremely low probability is instantly changed into ash at the high temperature of the hearth and cannot survive, and then the gas in the hearth forms the flue gas of the fuel gas boiler and is discharged out of the boiler to enter the first flue gas waste heat coil 33. The heat exchange is carried out with the compressed air in the compressed air storage tank 21 to first flue gas waste heat coil pipe 33, promotes compressed air's temperature, further reduces the probability that the virus survives in the compressed air storage tank 21, and improves the compressed air's that gets into combustor 22 temperature, is favorable to promoting combustor 22's combustion efficiency, practices thrift the gas quantity, and is energy-concerving and environment-protective.
