Vertical pollution air anti-diffusion treatment device

Abstract

The invention discloses a vertical polluted air anti-diffusion treatment device, comprising: a box, which has an air outlet joint and a box body that are sealed and connected; the side of the box body is provided with a first opening, a second opening, and a third opening from bottom to top; a filtering device It includes a first filter assembly embedded in the first opening, a second filter assembly corresponding to the second opening, and a third filter assembly corresponding to the third opening position; the differential pressure measurement device includes a The first micro-pressure differential gauge and the second micro-pressure differential gauge connected to the air inlet end of the third filter assembly; the detection device includes a detection port located above the third opening and a matching blind cover; the sealing and pressing device includes the second The filter assembly is sealed into the first sealing assembly in the box through the second opening, and the second sealing assembly is installed in the box in the third filter assembly through the third opening. The invention has the advantages of flexible installation and arrangement, overall compactness, good airtightness, convenient inspection, safety and reliability.

Description

technical field [0001] The invention relates to the technical field of clean air treatment and isolation, and more specifically, the invention relates to a vertical anti-diffusion treatment device for polluted air. Background technique [0002] The laboratory is a place for scientific research, routine experiments and teaching. There are many experiments in the laboratory and the scope is wide, and the laboratory is a place where the instruments and equipment are relatively concentrated. Therefore, the pollutants produced in the laboratory are extremely complex. Laboratory pollution can be divided into chemical pollution, physical pollution and biological pollution. The main sources of biological pollutants are viruses, bacteria, and fungi; they also include spills during the production of pharmaceuticals such as highly allergenic, strong microorganisms and spore products, and anti-tumor drugs. [0003] From a global perspective, due to the different scientific levels and ...

Problems solved by technology

[0005] However, there are following disadvantages in the existing technical solutions: 1. The requirements for indoor cleanliness are not high, and the air-conditioning system is only equipped with primary and secondary filters.

2. How to ensure the relative negative pressure in the room and the air discharged outside will not cause environmental pollution is rough and unscientific in the implementation

3. Risk of cross-contamination from room to room
