Inertia sand remover

Abstract

The invention discloses an inertia sand remover which comprises a ventilation pipeline. A dust collecting box with an opening facing the air inlet of the ventilation pipeline is disposed in the ventilation pipeline. A guide filter device which can filter sand blown by the wind and guide sand and dust to the dust collecting box is disposed between the dust collecting box and the wall of the ventilation pipeline. The dust collecting box is connected with a fan, and dust is discharged to an appointed position through the fan. The guide filter device comprises at least one shutter structure formed by a plurality of blades, the blades are bent, a zigzag air runner is defined between every two adjacent bent blades, and the air inlet of the zigzag air runner faces the air inlet direction of the ventilation pipeline. The inertia sand remover has the advantages that the sand remover is firm in structure and applicable to occasions with bad work conditions; the sand remover has a self-cleaning function and needs no daily maintenance; the dust removing efficiency of the sand remover is increased by 65% as compared with an existing filter device under the same conditions.

Description

technical field [0001] The invention relates to a filtering device, in particular to a device for automatically separating dust and air in dust-containing air. Background technique [0002] The so-called sandstorm activity is a series of sandstorms caused by strong winds acting on the dry surface. physical phenomenon . Usually fine particles of sand fly into the atmosphere, in a suspended state, and are affected by the spatial movement of the atmosphere. [0003] Experts from the China Environmental Monitoring Center use the concentration of suspended particulate matter in the air as a measure. The concentration of suspended particulates in Beijing during the recent dusty weather generally does not exceed 1,000 micrograms per cubic meter, while the concentration during sandstorms far exceeds this index. [0004] High dust content in the air can easily cause people to suffer from respiratory and gastrointestinal diseases, and will also adversely affect the normal operation...

Problems solved by technology

[0004] The high dust content in the air can easily cause people to suffer from respiratory and gastrointestinal diseases, and will also adversely affect the normal operation of some equipment

[0005] In Northwest China, there is a lot of sand and dust in the air, and the primary filter will quickly fail or be damaged and needs to be replaced frequently. In harsh environments such as sandstorms, the primary filter will fail in a few minutes

In addition, the existing sand and dust air separation device has a relatively simple structure and cannot be used in combination with the central air-conditioning system, and the filtered sand needs to be manually cleaned and discharged regularly.
