Description
Technical Field
The utility model relates to medical equipment, in particular to an exhaust disinfection device.
Background
At present, various viral infectious diseases are continuously appeared in the world, and particularly, new viruses are high in outbreak and can infect a large number of patients by epidemic situations in a short time. Because of the bed limitation of the existing infectious disease hospitals, the method is difficult to deal with for a national province and a city, only ordinary hospitals are changed into temporary infectious disease hospitals to receive infected patients, or temporary emergency ward construction, or shelter hospitals are established by utilizing emergency of school stadiums, and the like, but the emergency temporary infectious disease hospitals pollute the surrounding environment if the externally discharged air is not disinfected due to the concentration of the patients, and some virus and germs infected by the air can be continuously transmitted to the surrounding crowds, so that the spread of the epidemic situation is difficult to control.
SUMMERY OF THE UTILITY MODEL
Aiming at the problem of exhaust purification and disinfection of the temporary infectious disease hospital, the invention provides the exhaust purification and disinfection system which can be quickly installed and put into use as soon as possible.
An exhaust gas disinfection and purification system of an infectious disease hospital is characterized in that:
the system comprises a ventilation system, an atomization disinfection system, an ultraviolet sterilization device and a filtering reflux device; the ventilation system is characterized in that exhaust fans are installed on ventilation openings of wards of an infectious disease hospital, and the outlet of each exhaust fan is provided with a one-way valve and connected with an air delivery branch pipe; an air delivery main pipe is arranged at a proper position passing through the sickrooms in rows; the air delivery branch pipes of all the wards are communicated with the air delivery main pipe;
the atomization disinfection system is characterized in that an atomization nozzle is arranged at the inlet end of the air delivery main pipe, the atomization nozzle is connected with a high-pressure water pump and a pneumatic pump, the water inlet of the high-pressure water pump is arranged in a disinfection liquid medicine pool, and disinfection liquid medicine mist is delivered into the air delivery main pipe through the atomization disinfection system;
the ultraviolet sterilization device is characterized in that an ultraviolet sterilization disinfection lamp is arranged in a section of pipeline, and the ultraviolet sterilization device is connected in series with the outlet end of the air delivery main pipe;
the filtering and refluxing device is characterized in that a section of vertical pipe is arranged at the tail end of the air conveying main pipe, the bottom of the vertical pipe is connected with a condensate water reflux pipe, and the condensate water reflux pipe is communicated with a waste liquid tank; the outlet of the vertical pipe is provided with a medical filter screen.
When the infectious disease hospital is a temporarily built shelter hospital, the exhaust fans are arranged at the top of each compartment in the shelter due to the shared roof, and a plurality of rows of exhaust fans are uniformly arranged at the top of the shelter without the compartments, so that sufficient exhaust volume is ensured.
The working procedure is as follows: when the infectious ward exhausts and disinfects, disinfectant liquid is added into a disinfectant liquid pool, all exhaust fans and an atomization disinfection system are started, polluted air in the ward is exhausted into an air delivery main pipe through a one-way valve and is mixed with the pesticide mist with the grain diameter of several microns sprayed by an atomization nozzle, so that virus and germs suspended in the air, particularly the virus and germs with the diameter of less than 5 microns, are preliminarily sterilized and killed again when passing through an ultraviolet sterilization device, and finally, the air is filtered by a medical filter screen, so that the exhausted air reaches the nontoxic cleaning index, and condensed wastewater flows into a waste liquid tank through a condensate water return pipe. The medical filter screen is replaced and concentrated for recovery and destruction at regular time.
The beneficial effects of the utility model are that, because the contaminated air of infectious ward exhaust is filtered through a series of killing, obtains thoroughly purifying, no longer causes secondary pollution to the air around the hospital. The utility model has low construction cost and quick construction speed, and is suitable for the emergency of epidemic situation of infectious diseases.
