Cooking fume pollution treatment device used on roof

Abstract

The invention discloses a cooking fume pollution treatment device used on a roof and relates to the technical field of waste gas treatment. The cooking fume pollution treatment device comprises an exhaust filtering component, wherein the exhaust filtering component is connected with the top end of a chimney; a partition guide cylinder is connected above the exhaust filtering component in an insertion manner; an oil collection filtering cover is fixed above the exhaust filtering component and on the circumferential side of the partition guide cylinder through bolts; the exhaust filtering component comprises a rectangular base plate; a rectangular air tube is fixed on the lower surface of the rectangular base plate in a penetration manner; an annular oil storage groove, an annular insertiongroove and a water filtering groove are fixed in sequence from inside to outside on the upper surface of the rectangular base plate and in a coaxial line with the rectangular air tube; a pipeline fanis fixed between a pair of opposite walls of the rectangular air tube; and the lower end of the partition guide cylinder is connected inside the annular insertion groove in an insertion manner. Due todesigning of the exhaust filtering component, the partition guide cylinder and the oil collection filtering cover of the device, cooking fume can be firstly coagulated through multi-stage cooking fume filtering, the cooking fume filtering completeness is high, the cost is low, and the problem that a device for treating waste gas of a fume well on a roof is not available at present can be solved.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a device for treating oil fume pollution on roofs. Background technique [0002] With the development of urbanization, the density of buildings is gradually increasing. All the fume in the building is discharged upwards from the fume well, and released into the air on the roof. Because the fume contains a large amount of atomized oil mist particles, it will be released along with the dust. Subsidence causes corrosion to the surface of flowers, trees and vehicles, increasing air pollution. The existing smoke exhaust wells on the roof use direct exhaust to discharge the oil fume into the air without treatment, which aggravates the environmental pollution problem. Therefore, it is necessary to design a special smoke treatment device to solve the problem of smoke wells on the roof. The problem of oily smoke. Contents of the invention [0003] The purpose o...

Problems solved by technology

[0003] The purpose of the present invention is to provide a device for treating oily fume pollution on the roof. Through the designed air extraction filter assembly, separation guide tube, and oil collection filter cover, the oily fume is first condensed through multi-stage oily fume filtration, and the oily fume is filtered. High degree of completion and low cost, which solves the existing problem that there is no exhaust gas from the smoke well on the roof
