Oil fume air purifier with negative pressure collection function

Abstract

The invention relates to the technical field of air treatment equipment, in particular to a lampblack air purifier with a negative pressure collection function. Comprising a shell, an oil filter screen, a negative pressure fan, an oil box and a particle adsorption assembly, and the particle adsorption assembly comprises an electrostatic high-voltage discharge electrode, a positive plate, a negative plate, a dust collection screen and a dust collection box; flue gas enters the shell under the negative pressure attraction force of the negative pressure fan, oil smoke particles are filtered out through the oil filter screen, then the flue gas enters the electrostatic high-voltage discharge electrode, high-voltage positive ions are injected into the flue gas through the electrostatic high-voltage discharge electrode, dust particles with positive charges can be adsorbed to the negative plate, and dust particles with negative charges can be adsorbed to the negative plate. And then residual dust particles are blocked by the dust collecting net and fall into the dust collecting box, and finally the purified smoke is discharged through the smoke outlet in the right side of the shell, so that the lampblack particles and the dust particles in the smoke can be filtered, and the influence on the atmospheric environment after emission is avoided.

Description

technical field [0001] The invention relates to the technical field of air treatment equipment, in particular to an oil fume air purifier with negative pressure collection. Background technique [0002] The oil fume air purifier is a device used to extract oil fume during cooking, but the existing oil fume air purifiers directly discharge the oil fume into the atmospheric environment, and the oil fume particles and dust particles in the oil fume are directly discharged into the air. will have an impact on the atmospheric environment. [0003] At present, the prior art discloses an oil fume air purifier, which absorbs oil fume particles and dust particles in the oil fume by arranging a static cooling oil filter at the position of the smoking port of the oil fume air purifier. [0004] However, in the above method, only the static cooling oil filter is used to absorb the soot particles and dust particles in the oil fume. When the amount of smoke is large, some dust particles ...

Problems solved by technology

[0004] However, with the above method, only the static cooling oil filter is used to absorb the oil fume and dust particles in the oil fume. When the amount of smoke is large, some dust particles will still pass through the static cooling oil filter and be directly discharged into the atmosphere. In the middle, the filtering effect on dust particles is insufficient, resulting in an impact on the atmospheric environment
