The air supply and purification system of the biosafety inspection vehicle

Abstract

Disclosed is an air supply purifying system of a biological safety inspection vehicle. The air supply purifying system of the biological safety inspection vehicle is provided with an all-fresh-air air conditioning unit and an air feeder which are connected with each other and arranged on a bottom plate. An outdoor unit of the all-fresh-air air conditioning unit is arranged outside. An air outlet of the air feeder is connected with an air inlet of a biological safety purifying device through a first diameter changing part, a flexible connection pipeline and a bend which are sequentially connected, and an air outlet of the biological safety purifying device is connected with an air inlet of an air-flow distribution box. One path of air coming out of the air-flow distribution box flows to an air channel of an experiment room and enters the experiment room through a fixed blast capacity regulating valve, a second diameter changing part, a biological sealing valve, a static pressure box and an air supply duct which are arranged in sequence, and the other path of air flows to an air channel of a buffer room and enters the buffer room through a regulating valve and an air supply outlet sequentially. An air inlet of the all-fresh-air air conditioning unit is arranged in a primary filter on an air inlet of an air supply air-treating equipotent room on a rear side plate of the air supply air-treating equipotent room in a connecting mode through a medium efficiency filter. By means of the air supply purifying system of the biological safety inspection vehicle, it is guaranteed that personnel and experiment samples in a lab cannot be contaminated by the outside, and detection results are true and effective.

Description

technical field [0001] The invention relates to an air supply purification system. In particular, it relates to an air supply purification system of a biological safety inspection vehicle. Background technique [0002] In recent years, due to factors such as changes in the natural ecological environment, imbalances in the ecosystem, and decline in environmental quality, the chances of emerging acute infectious diseases worldwide have shown an upward trend. The incidence of infectious diseases in my country is severe. The total number of patients with tuberculosis and schistosomiasis remains high. Imported cases of schistosomiasis are on the rise in some areas. New infectious diseases such as SARS, avian influenza, Streptococcus suis, and Influenza A H1N1 continue to emerge and become popular. , Infectious diseases imported from abroad, such as dengue fever and malaria, appeared local epidemics. In view of the above situation, the specific goals of my country's emerging acut...

Problems solved by technology

[0005] General testing laboratories do not have cleanliness requirements, but simply send air into the laboratory through fans and valves

The higher-level laboratories use filters installed at the air outlets of each area of ​​the laboratory to purify the air. The installation of equipment is more complicated, and the requirements for the height of the laboratory are very high, requiring a special space for high-efficiency air filtration. for maintenance and replacement
