Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings and examples:
example 1: as shown in fig. 1, the present invention comprises an exhaust fan 2 having an inlet communicated with an outlet of an exhaust gas discharge pipe 1, a chamber 4 having an insulating layer 3 on a chamber wall communicated with an outlet of the exhaust fan 2 (an air inlet of the exhaust fan 2 is provided with a valve so as to close the valve when the exhaust fan 2 is replaced/repaired), a gas heating device 5 disposed in the chamber 4, a regulating valve 7 disposed between the exhaust fan 2 and the chamber 4 or at a gas discharge port 6 at an upper portion of the chamber 4, a multi-layer gas heating device 5 disposed from bottom to top in the chamber 4, an exhaust gas discharged from the exhaust gas discharge pipe 1 connected to a septic tank a being fed into the chamber 4 through the exhaust fan 2 and being rapidly heated to 50 to 200 ℃ in the chamber 4, and then staying in the chamber 4 (as a new coronavirus, which survives in an environment at 100 ℃ for 3 minutes, and further, the shorter the time for virus killing with the increase of temperature) until the virus is killed at a high temperature, and then the virus-killed exhaust gas is discharged to the atmosphere through the gas discharge port 6.
An exhaust port 10 with an electric valve 9 is arranged on an air guide channel 8 between the waste gas discharge pipeline 1 and the exhaust fan 2, a control device 11 for controlling the exhaust fan 2 controls the normally open electric valve 9 to act, and when the exhaust fan 2 stops working (such as shutdown due to a fault), the control device 11 controls the electric valve 9 to open so as to ensure that waste gas can be smoothly discharged into the atmosphere and prevent the waste gas from flowing backwards into a toilet of a resident.
The gas heating device 5 comprises a heat radiator (such as aluminum alloy) which is made of materials with large specific heat capacity and large heat exchange area, and an electric heating device (such as an electric heating wire) arranged in the heat radiator, wherein the heat radiator adopts an aluminum alloy sunflower heat radiating fin.
The cavity 4 is provided with a plurality of clapboards 12 from bottom to top, the cavity 4 is divided into a plurality of layers of channels 13, the adjacent channel layers are communicated end to form a snake-shaped channel, and the gas heating device 5 is arranged in each layer of channels 13. The serpentine channel is adopted, so that not only is stable heating of waste gas facilitated, but also sufficient time for the waste gas to stably stay in the accommodating cavity at high temperature is facilitated, and viruses in the waste gas are guaranteed to be killed.
A temperature detector c is arranged in the cavity 4, the electric signal output of the temperature sensor c is connected with the electric signal input of the control device 11, and the detected temperature and the working states of the exhaust fan 2 and the electric valve 9 are transmitted to the remote monitoring platform b by the control device 11 through the internet so as to be monitored by a management department.
The outlet of the exhaust gas discharge pipe 1 is connected to a gas discharge port 19 of a check valve 18 that opens at positive pressure. The gas discharge port 19 with the check valve 18 is arranged to prevent air lock from being formed due to the fact that air pressure in the waste gas discharge pipeline 1 is positive pressure caused by accidents (for example, water in a septic tank overflows into the waste gas discharge pipeline 1 due to heavy rain, a large amount of air is brought into the waste gas discharge pipeline 1 during toilet flushing, the brought air easily enables the waste gas discharge pipeline 1 to form positive pressure, and the toilet cannot be smoothly flushed with water due to the air lock), so that the toilet cannot be flushed with water normally. This problem is solved by the above-mentioned technique in that when the pressure in the exhaust gas discharge pipe 1 rises to a positive pressure, the check valve 18 is opened to prevent the pressure from rising further and forming an air lock.
The outlet of the exhaust gas discharge pipe 1 is connected with a gas inlet 21 of a check valve 20 which is opened in a micro negative pressure state. When using the water-washed lavatory pocket simultaneously in a plurality of toilets in the building, when a large amount of sparge water falls into the septic tank, can produce higher negative pressure in the twinkling of an eye in exhaust emission pipeline 1, thereby can influence the sparge water and fall into the septic tank fast, thereby influence the effect of washing, this problem has just been solved to the gas inlet 21 that adopts to have check valve 20, after the negative pressure in exhaust emission pipeline 1 reaches a definite value, check valve 20 opens, thereby avoid the emergence of above-mentioned unfavorable condition.
Example 2: as shown in fig. 2, based on embodiment 1, the present invention is provided with a plurality of waste gas collecting pipes 15 having waste gas inlets 14, the waste gas inlets 14 are provided with valves 16, the waste gas inlets 14 of the waste gas collecting pipes 15 are communicated with a waste gas discharging pipeline 1, a waste gas collecting pipe 13 is communicated with the lower portion of the chamber 4 through two sets of exhaust fans 2, each set of exhaust fans 2 is provided with a valve 17 at an inlet and an outlet, waste gas discharged from a plurality of waste gas collecting pipes 1 of a building is introduced into the waste gas collecting pipe 15 through the waste gas inlets 14, then introduced into the lower portion of the chamber 4 through one set of exhaust fans 2, heated to a set temperature by the gas heating device 5 in the chamber 4 and stayed in the chamber 4 for a sufficient time, and viruses in the waste gas are killed at a high temperature and then discharged to the atmosphere from the gas discharging port 6 of the.
Two sets of exhaust fans 2 are adopted, and even if one set of exhaust fan 2 cannot work, the uninterrupted virus killing treatment on the waste gas can be ensured. When one of the exhaust fans 2 is out of operation (e.g., not working due to a failure), the control device 11 controls the other exhaust fan 2 to operate, and simultaneously sends out a warning to the management department (e.g., the control device 11 sends out a warning with position information to the remote monitoring platform b through a network), so that the management department can repair or replace the failed exhaust fan 2 in time.
