Description

Front-mounted gas disinfection device for hospital central suction station

Technical Field

The utility model relates to a front-mounted hospital central suction station gas disinfection device.

Background

The vacuum pump of current hospital central suction station generally uses the water ring vacuum pump, and the air that during operation inhales from the ward is discharged into gas-water separator with the circulating water in the vacuum pump together, and waste gas passes through the blast pipe and discharges. The air inhaled by the ward generally carries pathogenic bacteria or viruses, and if effective disinfection and sterilization are not carried out in the system pipeline, a hospital pollution source is formed, and great potential safety hazards exist. Particularly, in the work of preventing and controlling 2019 novel coronavirus infection pneumonia, various hospitals take a lot of emergency measures for eliminating the hidden trouble, but generally carry out disinfection and sterilization and filtration on the exhausted air at the exhaust port of a central suction station, and although the air has a certain effect, the effect of eliminating the hidden trouble is still difficult to achieve. The reasons are: the vacuum pump of the central suction station works intermittently, the working time is short, and the exhaust port does not exhaust air in most of time, so that the sterilization effect on the exhaust port is avoided; the exhaust volume is very large when the vacuum pump works, for example, the pumping flow of a commonly used 2BV5121 vacuum pump can reach 4.66m³Min, a large amount of gas is discharged from the exhaust port during work, and all disinfection measures are difficult to disinfect the discharged large amount of gas in a short time; because polluted air enters the vacuum tank and the vacuum pump before being exhausted, the central suction station is polluted, and particularly, circulating water in the central suction station overflows to form a new pollution source.

SUMMERY OF THE UTILITY MODEL

There is the pollution hidden danger in order to eliminate central attraction station, solves the not good problem of current disinfection measure disinfection effect, the utility model provides a set up the gaseous degassing unit who attracts the station front end at the center, the air of pollution is through sealed gaseous degassing unit, utilizes the water-bath method to let the air of pollution fully contact with disinfectant to reach the disinfection and isolation effect.

The utility model provides a technical scheme that its technical problem adopted is: a front-mounted gas disinfection device comprises a stainless steel tank body, a plastic disinfection liquid barrel, a disinfection liquid, a liquid adding/discharging pipe, a negative pressure meter, a liquid level pipe, a liquid adding/discharging valve, an air inlet pipe, an exhaust pipe, a drain outlet, a gas-water mixer and a gas-water separator.

An air inlet pipe and an exhaust pipe are arranged at the upper part of the stainless steel tank body, and a sewage draining outlet is arranged at the lower part of the stainless steel tank body. Forming a closed gas disinfection device housing.

The plastic disinfectant barrel is arranged inside the stainless steel tank body, and disinfectant is contained inside the plastic disinfectant barrel.

The liquid adding/discharging pipe is communicated from the outside of the stainless steel tank body to the inside of the plastic disinfectant barrel and is used for adding and discharging disinfectant.

The liquid level pipe is arranged on the stainless steel tank body, the lower end of the liquid level pipe is connected with the liquid adding/discharging pipe through the measuring valve and communicated to the inside of the plastic disinfectant barrel, and the liquid level in the plastic disinfectant barrel is measured through the communicating vessel principle.

The negative pressure meter is arranged outside the stainless steel tank body and used for measuring the air pressure value in the tank body.

The lower end of the air inlet pipe is connected with the air-water mixer, and the upper end of the air inlet pipe is connected with the suction pipe of the ward.

The gas-water mixer is immersed in the disinfectant.

The lower end of the exhaust pipe is connected with the gas-water separator, and the upper end of the exhaust pipe is connected with the central suction station gas inlet pipe.

The beneficial effects of the utility model are that, because contaminated air gets into the central vacuum tank that attracts the station in succession and slowly, the flow only attracts about 1/2 to 1/10 of the station gas vent in the center, in the leading-in plastics disinfectant bucket of intake pipe, gas-water mixer, fully contacts with the antiseptic solution, and the disinfection and isolation effect is very ideal. And because the air entering the central suction station is disinfected, the vacuum pump and the circulating water are not polluted, and the virus diffusion can be effectively controlled.

Detailed Description

[ example 1 ]

A preposed gas disinfection device for a central suction station of a hospital comprises a stainless steel tank body 1, a plastic disinfection liquid barrel 2, a disinfection liquid 3, a liquid adding/discharging pipe 8, a negative pressure meter 6, a liquid level pipe 7, a liquid adding/discharging valve 10, a measuring valve 9, an air inlet pipe 4, an exhaust pipe 5, a sewage discharge outlet 11, a gas-water mixer 12, a gas-water separator and a gas-water separator 13. An air inlet pipe 4 and an exhaust pipe 5 are arranged on the upper portion of the stainless steel tank body 1, a sewage discharge outlet 11 is arranged on the lower portion of the stainless steel tank body 1, the stainless steel tank body 1 forms a sealing shell of the gas disinfection device, the plastic disinfection liquid barrel 2 is arranged inside the stainless steel tank body 1, disinfection liquid 3 is contained inside the plastic disinfection liquid barrel 2, the lower end of the air inlet pipe 4 is connected with a gas-water mixer 12, and the gas-water mixer 12 is immersed into the disinfection liquid 3.

The air inlet pipe 4 is connected with a ward suction pipeline 14, the exhaust pipe 5 is connected with an air inlet pipe 15 of a central suction station, and the stainless steel tank body 1 is communicated with the vacuum tank 16 due to the fact that negative pressure is inside the vacuum tank 16 of the central suction station, and the inside of the stainless steel tank body 1 is also negative pressure. The gas in the ward is sucked into the disinfection tank through the ward suction pipeline 14 and the air inlet pipe 4, and is in mixed contact with the disinfection solution 3 through the gas-water mixer 12, so that the disinfection effect is realized. The sterilized gas is separated by a gas-water separator 13 to obtain residual disinfectant, and the disinfectant enters a central suction station vacuum tank 16 through an exhaust pipe 5 and a central suction station air inlet pipe 15, and is finally discharged through a central suction station exhaust pipe 18.

When the vacuum pump 17 of the central suction station works, the vacuum tank 16 of the central suction station and the stainless steel tank body 1 are internally provided with negative pressure, the measuring valve 9 is closed, the liquid adding/discharging valve 10 is opened, and disinfectant is sucked into the plastic disinfectant barrel 2 through the liquid adding/discharging pipe 8 by utilizing the negative pressure in the stainless steel tank body 1. After the vacuum pump 17 of the central suction station stops working, the measuring valve 9 is closed, the liquid adding/discharging valve 10 is opened, the sewage discharging port 11 is opened, and the disinfectant 3 in the plastic disinfectant barrel 2 can be discharged through the liquid adding/discharging pipe 8 by utilizing the siphon principle. Opening the measuring valve 9 and closing the liquid adding/discharging valve 10 allows the liquid level in the sterilizing liquid tank 2 to be observed through the liquid level pipe 7.

[ example 2 ]

The gas-water mixer 12 may be composed of a single or multiple concentric plastic tubes, the surface of the plastic tube is distributed with dense fine vent holes 21, and the vent holes 21 are circular or polygonal. The sucked gas enters the sterilizing liquid 3 in the form of fine bubbles by the action of the vent 21, thereby achieving sufficient contact with the sterilizing liquid 3 and sterilization.
