Compared with the prior art, the utility model has the advantages of automatically adjusting the air pressure in the defecation pipeline to ensure that excrement in the urinal of the building is smoothly flushed into the defecation pipeline, along with simple structure and low cost, and simultaneously, the utility model can also smooth the rapid fluctuation of the external air pressure and ensure that the virus in the waste gas is smoothly killed at high temperature.
Description
Technical Field
The utility model relates to a waste gas purification treatment technology.
Background
The existing building is characterized in that waste gas discharge pipelines which directly reach the roof are arranged on septic tanks of the existing building, so that foul gas generated in the septic tanks is discharged to the high altitude, the pollution of the foul gas to living environments of residents is avoided, evidence shows that viruses can survive in excrement, the viruses can be dispersed into the waste gas and discharged to the high altitude along the waste gas discharge pipelines along with the waste gas, and then the viruses fly away along with the air, so that the risk of infecting people is further caused. Therefore, the utility model provides a gas purifier capable of killing viruses, which kills the viruses in dirty gas flowing through the gas purifier at a set temperature for a period of time in a heating mode. Because the sewage gas stays for enough time at high temperature so as to fully kill the virus in the sewage gas, a device for controlling the flow rate of the sewage gas is needed, and the device does not influence the flushing of a urinal in a building under normal conditions, but in some special occasions, such as rainstorm, when water in a septic tank overflows a defecation pipeline, the flow rate of the gas controlled by the device is very low, so that the phenomenon of air lock is caused, and the excrement in the septic tank cannot be smoothly flushed into the defecation pipeline; if the toilet is flushed in a plurality of buildings in the same building, the excrement flushed into the excrement pipeline and moved downwards can cause negative pressure to be formed in the excrement pipeline, at the moment, the negative pressure in a short time is large due to the fact that the flow rate of the gas controlled by the device is low, the excrement is easy to stay in the pipeline, and the accumulated excrement can cause blockage of the excrement pipeline. To this end, the present inventor invented a control mechanism capable of automatically controlling the air pressure in the drain pipe to maintain a stable air pressure, the control mechanism including an electric valve, a control device, and an air pressure sensor, and the control mechanism can solve the above problems, but the control mechanism has a complicated structure and high manufacturing and using costs, and therefore, the present applicant applied for the respirator of patent CN2020221562194 to automatically adjust the air pressure in the drain pipe to ensure that the excrement in the urinal of the building is smoothly flushed into the drain pipe, but since the valves are located outside, even if protective measures (such as dust caps) are adopted, the respirator is easily damaged by the influence of unstable external factors (such as strong wind/heavy rain) at high altitude, and further, since the valves are directly connected to the outside, the instantaneous external air pressure instability can immediately cause the respirator to operate, and the respirator is frequently opened and closed, the stability of the airflow in the defecation pipeline is obviously influenced, so that the smooth high-temperature virus killing is influenced.
