It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

The first embodiment is as follows:

as shown in fig. 1 and 2:

a disinfection apparatus comprising a housing 1 having a chamber 11;

the shell 1 is detachably arranged at an air outlet of the main drainage vertical pipe 5, a spiral guide channel 2 is arranged on the outer side wall of the shell 1, and the outlet of the guide channel 2 is communicated with the chamber 11;

the disinfection device 3 and the air outlet pipe 13 are arranged in the cavity 11, the air inlet end of the air outlet pipe 13 is arranged close to the bottom wall of the cavity 11, and the air outlet end of the air outlet pipe 13 penetrates through the shell 1 to be communicated with the outside.

Preferably, the housing 1 is provided with a clamping part 12; the sterilizing equipment is fixed at the air outlet of the main drainage vertical pipe 5 through the clamping part 12, so that the sterilizing equipment is more convenient to install.

When the disinfection equipment is installed, the disinfection equipment is installed and fixed at an air outlet of a main drainage vertical pipe 5 through a clamping part 12, most of the shell 1 is positioned in the main drainage vertical pipe 5 so as to avoid the situation of being blown away by wind, and gas discharged outwards in the main drainage vertical pipe 5 enters the cavity 11 through the guide channel 2 and is discharged outwards through the exhaust pipe;

specifically, when the main drainage vertical pipe 5 is in a positive pressure state, the gas in the main drainage vertical pipe 5 enters the chamber 11 through the spiral guide channel 2, infectious aerosol in the gas entering the chamber 11 is attached to the side wall of the chamber 11 under the action of centrifugal force due to cyclone effect, sterilization treatment is performed under the action of the sterilizing device 3, and the gas and the aerosol after the sterilization treatment can be discharged to the atmosphere through the gas outlet pipe 13;

when the main drainage vertical pipe 5 is in a negative pressure state, external air can freely enter the chamber 11 through the air outlet pipe 13 and then enter the main drainage vertical pipe 5 through the spiral guide channel 2.

Preferably, the bottom wall of the chamber 11 is in an inverted cone structure, the middle part of the bottom wall is provided with a water outlet 14, that is, the water outlet 14 is arranged at the lowest point of the chamber 11, a ball 15 for plugging the water outlet 14 is further arranged in the chamber 11, and the density of the ball 15 is less than that of water;

when rainwater enters the chamber 11 through the air outlet pipe 13, the rainwater can be accumulated on the bottom wall of the chamber 11, the ball 15 can float upwards under the action of buoyancy of the water, at the moment, the water outlet 14 in the middle of the bottom wall can be opened, and the rainwater accumulated on the bottom wall can be discharged into the main drainage vertical pipe 5 through the water outlet 14, so that the situation that the disinfection device 3 is damaged due to excessive rainwater is avoided; after the rainwater is drained out of the chamber 11, the ball 15 will move to the initial position along the bottom wall to block the water outlet 14, so as to effectively prevent the gas in the main drainage vertical pipe 5 from entering the chamber 11 from the water outlet 14.

Preferably, the disinfection device further comprises a cover plate 4; wherein the content of the first and second substances,

the cover plate 4 is fixedly arranged at the top of the shell 1, and the air outlet end of the air outlet pipe 13 is positioned below the cover plate 4; when raining, rainwater can fall on the cover plate 4 and flow along the circumferential direction of the cover plate 4 towards the exhaust port of the main drainage vertical pipe 5, so that the amount of rainwater flowing into the chamber 11 is reduced, and a certain gap is formed between the cover plate 4 and the air outlet end of the air outlet pipe 13, so that the arrangement of the cover plate 4 cannot influence the emission of gas.

Note that, the top of the housing 1 means: when the disinfection apparatus is installed at the air outlet of the main drain stand pipe 5, the end of the housing 1 located outside the air outlet is the top of the housing 1.

Preferably, the air inlet end of the air outlet pipe 13 is provided with a bell mouth 131, and the smaller end of the bell mouth 131 is communicated with the air inlet end of the air outlet pipe 13;

the flare 131 can effectively reduce the flow rate of the gas in the chamber 11 to prevent the aerosol adsorbed on the sidewall of the chamber 11 from being re-aerosolized and discharged to the atmosphere through the outlet pipe 13.

Preferably, the disinfection device 3 comprises an ultraviolet lamp and a photocatalyst layer; wherein the content of the first and second substances,

the photocatalyst layer is arranged on the side wall of the chamber 11, the ultraviolet lamp is arranged on the outer side wall of the air outlet pipe 13, the photocatalyst layer generates active oxygen under the action of ultraviolet light or other visible light, and infectious aerosol adsorbed on the side wall of the chamber 11 is oxidized and decomposed into substances such as carbon dioxide, water and the like, so that the emission of the infectious aerosol is effectively reduced.

In addition, the ultraviolet lamp in the disinfection apparatus 3 may be replaced by other visible light capable of activating the activity of the photocatalyst layer, and the disinfection apparatus 3 may be configured to disinfect infectious aerosol.

The bell-mouth 131 can also effectively block the light of the ultraviolet lamp to prevent insects from being attracted by the light emitted by the ultraviolet lamp and entering the chamber 11.

Preferably, the area of the cross section of the guide channel 2 decreases from the inlet of the guide channel 2 to the outlet of the guide channel 2, and the arrangement is such that the flow velocity of the gas in the main exhaust gas vertical pipe is increased when the gas passes through the guide channel 2, so that the centrifugal force to which the aerosol in the gas is subjected when the aerosol in the gas enters the chamber 11 is increased, and the aerosol in the gas is more easily attached to the side wall of the chamber 11.

Preferably, the housing 1 has a cylindrical structure, and the outlet of the guide channel 2 is formed along the tangential direction of the housing 1, so that the gas in the main drainage vertical pipe 5 can make circular motion along the side wall of the chamber 11 when entering the chamber 11, thereby improving the adhesion effect of the aerosol in the gas.

Preferably, the clamping portion 12 is provided with a clamping groove for conveniently clamping the housing 1; wherein the content of the first and second substances,

the opening of draw-in groove sets up towards the bottom of casing 1, when this disinfecting equipment of installation, can establish the card that the opening of draw-in groove corresponds on the lateral wall of the gas vent of main drainage riser 5 to it is fixed to accomplish the installation of this casing 1, makes this disinfecting equipment's installation more convenient.

Preferably, a sealing gasket is arranged in the clamping groove; the sealing gasket can increase the sealing effect between the shell 1 and the exhaust port of the main drainage vertical pipe 5, so as to avoid the condition that gas leaks from the gap between the shell 1 and the main drainage vertical pipe 5.

Example two:

as shown in fig. 1 and 2:

a method of treating contaminated gas in a drainage system, carried out by the disinfection apparatus of embodiment one, the method comprising the steps of:

the contaminated gas is accelerated through the spiral guide channel 2 and enters the chamber 11;

pollutants in the polluted gas are adsorbed on the side wall of the chamber 11 under the action of centrifugal force and are disinfected by the disinfection device 3;

the gas after the disinfection treatment is discharged to the atmosphere through the gas outlet pipe 13.

The method can remarkably reduce or eliminate the discharge of infectious aerosol in the main drainage stand pipe 5, so as to avoid the influence of the infectious aerosol on the environment and reduce the occurrence of the condition that the lives of surrounding residents are influenced.
