Description

Ventilation structure for clean room Technical Field The utility model relates to the technical field of ventilation structures, in particular to a ventilation structure for a clean room. Background The clean room is characterized in that pollutants such as microparticles, harmful air and bacteria in the air in a certain space range are removed, indoor temperature, cleanliness, indoor pressure, air flow speed and air flow distribution, noise vibration, illumination and static electricity are controlled in a certain requirement range, a specially designed room is provided, an air inlet mechanism and an air outlet mechanism of a ventilation system of the clean room respectively need to filter air, and dust in the outside air is prevented from entering the clean room. Through searching, the patent (application number: 202020442659.3) discloses a clean room ventilation device which can eliminate peculiar smell gas in the air so as to perform primary air purification effect, and an electrostatic generator is arranged to remove and adsorb microorganisms and fine dust pollutants in the air so that the air purification effect can achieve an ideal effect and the air inhaled by the ventilation device is cleaner; However, in the use process of the device, particles such as adsorbed dust can be accumulated on the surface of the filter element due to long-time work, so that the filtering and adsorbing effect of the filter element is affected, and the filter element is cleaned manually, which is time-consuming and labor-consuming.
