Fine particulate matter ventilation fan equipment based on convection principle

Abstract

The invention relates to the technical field of fine particulate matter treatment, and discloses a fine particulate matter ventilation fan equipment based on a convection principle. The equipment comprises an equipment main body, an air filter curtain and a driving device, wherein an air inlet channel is formed in the outer wall of the equipment main body, and a bidirectional exhaust fan is arranged on the inner side of the air inlet channel; disinfection pools are arranged inside the equipment main body, back suction fans are arranged inside the disinfection pools, and the outer sides of theback suction fans are movably connected with disinfection spraying heads; and the air filter curtain is arranged inside the equipment main body. According to the fine particulate matter ventilation fan equipment based on the convection principle, when fresh air enters a room, the fresh air can reach the air filter curtain first, and the air filter curtain is used for absorbing dust and particulatematter of the outdoor air, so that the purpose of replacing and purifying indoor air is achieved; and meanwhile, the back suction fans can rotate to pump out disinfectant in the disinfection pools, the disinfectant is sprayed out from the disinfection spraying heads and is adhered to the air filter curtain, so that the equipment has the function of disinfecting the fresh air.

Description

technical field [0001] The invention relates to the technical field of PM2.5 control, in particular to a PM2.5 ventilation fan device based on the convection principle. Background technique [0002] At present, fine particles are also called fine particles, fine particles, and PM2.5. Fine particles refer to particles with an aerodynamic equivalent diameter of less than or equal to 2.5 microns in the ambient air. They can be suspended in the air for a long time, and their concentration in the air The higher the value, the more serious the air pollution. [0003] At present, indoor air pollution is becoming more and more serious, especially in the north. In many places, the indoor and outdoor air PM2.5 index is often in a bad state, and some places reach moderate pollution, which affects people's health. At present, most of the PM2.5 filter equipment on the market use activated carbon filter layer. Although it has a good effect, due to the short duration of activated carbon f...

[0003] At present, indoor air pollution is becoming more and more serious, especially in the north. In many places, the indoor and outdoor air PM2.5 index is often in a bad state, and some places reach moderate pollution, which affects people's health. At present, most of the PM2.5 filter equipment on the market use activated carbon filter layer. Although it has a good effect, due to the short duration of activated carbon filtration, frequent replacement is required, and it is not easy for people to find out whether activated carbon still has the filtering effect. , and the cost is higher
