Maintenance-free front lampblack purifying device

Abstract

The invention relates to a lampblack purifying device, in particular to a maintenance-free front lampblack purifying device without maintenance and cleaning and with three-dimensional intake. The device comprises a lampblack protective cover, a fan impeller and an external smoke cover wall; the lampblack protective cover is provided with a downwards opened horn port; the external smoke cover wall is provided with a downwards opened opening part; an opening adapted to the fan impeller is formed in the top of the external smoke cover wall; the fan impeller is arranged at the upper part of the opening; the lampblack protective cover is arranged at the lower part of the opening; an oil collecting tank is formed in the inner side wall of the external smoke cover wall; and polytetrafluoroethylene is coated on the inner surface of the external smoke cover wall and on the surface of the lampblack protective cover. As the polytetrafluoroethylene is coated on the inner surface of the external smoke cover wall and on the surface of the lampblack protective cover, the problem of disassembly cleaning is prevented. The protective cover and the protective cover surface of the lampblack protective cover are provided with holes, so that the smoke contact area is increased, the three-dimensional smoke suction is formed, and the working efficiency is improved.

Description

technical field [0001] The invention relates to an oil fume purification device, in particular to a maintenance-free front type oil fume purification device with maintenance-free cleaning and three-dimensional air intake. Background technique [0002] Among the sources of air pollution in cities, oil fume pollution from the catering industry has become one of the main sources of pollution. Among the environmental pollution complaints in cities, the oil fume pollution from the catering industry has accounted for about 50% of the total complaints. [0003] In the prior art, the purification methods commonly used in the catering industry include separation method, electrostatic precipitation method and liquid washing method, but the treatment efficiency is low. The thermal oxidation incineration catalyst purification method has high purification efficiency, but the technology is complicated and the operation cost is high. Although the existing front-mounted oil fume purifier h...
