Versatile Ventilation Unit with Sand Removal

Abstract

The invention relates to a multifunctional ventilating device with a sand removing function. The multifunctional ventilating device with the sand removing function comprises a shell, a power system, an inertia separating device and an air treating device, wherein the power system, the inertia separating device and the air treating device are arranged in the shell; an air inlet is formed in the bottom of one end of the shell; an air outlet is formed in the other end of the shell; air inlet shutters are arranged at the air inlet; air outlet shutters are arranged at the air outlet; the power system, the inertia separating device and the air treating device are sequentially arranged in the shell along the wind flowing direction; and the power system corresponds to the air inlet shutters. By using a negative-pressure type structure and the inertia centrifugal separating device, the multifunctional ventilating device with the sand removing function has the following advantages that the multifunctional ventilating device is free of maintenance and high in filtering efficiency and does not have consumable items.

Description

technical field [0001] The invention relates to a multifunctional ventilation device with sand removal function, which is mainly used for ventilation of buildings in areas with relatively large dust content. Background technique [0002] In deserts, Gobi and other environments, the outdoor dust content is relatively large. When ventilation facilities are used in buildings, if the corresponding sand removal measures are not adopted, the pollution inside the buildings will be serious. If the traditional filter interception is used, on the one hand, the service life of the filter will be reduced, on the other hand, the maintenance frequency and cost of the filter will increase significantly, and it cannot be used in many unmanned working environments. Although the anti-sand shutters used in the market can remove part of the sand and dust, the effect is not good because the problem of sand and dust emission is not solved. Contents of the invention [0003] The invention aims ...

Problems solved by technology

[0002] In deserts, Gobi and other environments, the outdoor dust content is relatively large. When the buildings use ventilation facilities, if the corresponding sand removal measures are not adopted, the pollution inside the buildings will be serious.

If the traditional filter is used to intercept, on the one hand, the life of the filter will be reduced, on the other hand, the maintenance frequency and cost of the filter will increase significantly, and it cannot be used in many unmanned working environments

Although the anti-sand shutters currently on the market can remove part of the sand and dust, the effect is not good because the problem of sand and dust emission is not solved.
