Description
Technical Field
The invention 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 invention 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 air 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. The applicant of the present invention has applied the respirator of CN2020221562194 to automatically adjust the air pressure in the toilet pipe to ensure that the excrement in the toilet of the building is smoothly flushed into the toilet pipe, but because the valve is located outside, even if a protection measure (such as a dust cap) is adopted, the respirator is easily damaged by an unstable external factor at high altitude (such as strong storm wind/heavy rain), and in addition, because the valve is directly connected with the outside, the instantaneous air pressure in the outside can immediately cause the action of the respirator, and the frequent opening and closing of the respirator can obviously influence the stability of the air flow in the toilet pipe, thereby influencing the smooth high-temperature virus killing.
Disclosure of Invention
The invention aims to provide an improved structure of a respirator, which can automatically adjust the air pressure in a defecation pipeline to ensure that excrement in a urinal of a building is smoothly flushed into the defecation pipeline, has a simple structure and low cost, and can also smooth the rapid fluctuation of the external air pressure to ensure that high-temperature waste gas virus killing is smoothly carried out.
The respirator comprises a main air pipe and a respirator body arranged on the main air pipe, and is characterized in that the respirator body comprises an air cavity, an expiration valve and an inspiration valve, wherein one side surface of the air cavity is connected with the main air pipe, the expiration valve and the inspiration valve are arranged on the side wall of the middle side surface of the air cavity, which is connected with the main air pipe, and a port, which is arranged on the air cavity and is communicated with the outside atmosphere.
When the respirator is used, the lower end of a main air pipe of the respirator is communicated with an outlet of a waste gas discharge pipeline which is arranged on a septic tank and directly reaches the roof, the upper end of the main air pipe is communicated with a high-temperature virus killing mechanism, under normal conditions, waste gas enters the high-temperature virus killing mechanism for treatment after passing through the main air pipe and then is discharged to the atmosphere, and when the air pressure in the waste gas discharge pipeline is higher than a set value (for example, rainstorm causes water in the septic tank to overflow the excrement discharge pipeline, and excrement is flushed in a urinal in a building), the air pressure in the waste gas discharge pipeline opens an exhalation valve, so that air blockage caused by the high air pressure in the waste gas discharge pipeline is avoided, and the excrement cannot be flushed into the waste gas discharge pipeline; when the air pressure in the waste gas discharge pipeline is lower than a set value (when excrement which is flushed into the excrement pipeline and moves downwards is flushed into the excrement pipeline, the excrement in a plurality of buildings simultaneously in the same building can cause the excrement pipeline to form overlarge negative pressure), the air suction valve is opened (at the moment, the air exhaust valve is in a closed state), and the outside air enters the waste gas discharge pipeline through the opening, communicated with the outside atmosphere, in the gas containing cavity to eliminate the generation of the negative pressure, so that the phenomenon that the excrement cannot smoothly fall into the septic tank and stays in the waste gas discharge pipeline due to the negative pressure in the waste gas discharge pipeline is avoided.
The gas cavity is arranged, so that even if the air pressure is unstable due to the fierce movement of the air flow outside, the fierce fluctuation of the air pressure can be moderated through the stabilizing effect of the gas cavity, and the frequent actions of the exhalation valve and the inhalation valve caused by the fierce fluctuation of the air pressure outside are prevented, so that the waste gas is influenced to smoothly enter the high-temperature virus killing mechanism for treatment.
Here, the opening of the gas cavity, which is communicated with the outside atmosphere, is communicated with the outside through a gas guide pipe, and the gas guide pipe is adopted, so that the drastic fluctuation of the outside air pressure can be further eased.
The air intake valve comprises an air intake port arranged on one side wall of the air cavity connected with the main air pipe and an air intake turning plate arranged on the inner side of the air intake port, wherein the air intake turning plate is connected with the upper edge of the outer side of the air intake port in a rotating mode through a shaft.
Or one side surface of the gas cavity connected with the main gas pipe is provided with an inwards concave cavity, the expiratory valve comprises an upper sealing structure arranged on the periphery of an expiratory port on the top cavity wall outside the inner cavity body, an outer support arranged on the top cavity wall outside the inner cavity body, and an outer cap buckled on the upper sealing structure and moving up and down along a guide structure on the outer support, the inspiratory valve comprises a lower sealing structure arranged on the periphery of the inspiratory port on the bottom cavity wall inside the inner cavity body, an inner support arranged on the bottom cavity wall inside the inner cavity body, and an inner cap buckled on the lower sealing structure and moving up and down along a guide structure on the inner support.
A spring is arranged between the outer cover cap and the outer bracket.
A spring is arranged between the inner cover cap and the inner support.
The invention has the advantages of simple structure, low cost, smooth fluctuation of the external air pressure and smooth high-temperature waste gas virus killing compared with the prior art.
