Smog purification device

Abstract

The invention discloses a smog purification device, which comprises a first fan, a filtering box connected with the first fan and a smog absorption pipeline connected with the filtering box, wherein glass fiber air paper which separates the filtering box into an upper cavity and a lower cavity is disposed in the filtering box. The upper surface of the glass fiber air paper is provided with first initial effect filter cotton, and the lower surface of the glass fiber air paper is provided with a metal screen board. A second fan is installed at the position of an opening on the top of the upper cavity of the filtering box, activated carbon is placed at the bottom of the upper cavity, and the upper surface of the activated carbon is also provided with first initial effect filter cotton. The top of the lower cavity of the filtering box is provided with second initial effect filter cotton, and a labyrinth separating plate is disposed in the lower cavity to form a labyrinth area. The activated carbon is placed in the labyrinth area, and second initial effect filter cotton is also disposed between the labyrinth area and an outlet of the lower cavity. The smog purification device is capable of absorbing smog or harmful gas quickly and effectively and improves purification effect.

Description

technical field [0001] The invention relates to the field of smoke purification treatment, in particular to a smoke purification device. Background technique [0002] During the process of arc welding, laser welding, engraving, marking, cutting, chemical laboratory, medical treatment, photoelectric surgery in cosmetology, etc., a large amount of smoke or harmful gas will be generated. If these smoke or harmful gas are directly discharged into the operating space, or Exhaust to the atmosphere through the ventilation system of the factory building will have adverse effects on the health of the operator and the environment. In order to solve this problem, people use smoke purifiers to absorb these smoke or harmful gases. [0003] Existing smog purifiers include a centrifugal fan (also a vacuum motor), a filter box connected to the centrifugal fan and a smoking pipe connected to the filter box, and activated carbon is placed in the filter box as an adsorption material. During p...

AI Technical Summary

Problems solved by technology

This smog purifier has the following two problems: one is that the smog or harmful gas is produced quickly, and the adsorption speed of activated carbon is not enough to completely absorb the smog or harmful gas that is produced quickly; the other is that due to the effect of the centrifugal fan, In the state of negative pressure, smoke or harmful gases that have been adsorbed by activated carbon may be desorbed, thus affecting the purification effect
