Internal circulation lampblack purifier

Abstract

The invention discloses an internal circulation lampblack purifier. The lampblack purifier comprises a casing, an air inlet, an air outlet, an air inlet channel, an air outlet channel, a fan device, amechanical grease separator, a gas purification device and a cooling device of the lampblack purifier, wherein the air inlet and the air outlet are arranged on the casing; the mechanical grease separator is arranged at the air inlet or in the air inlet channel; and the cooling device is arranged at the air outlet and comprises a water supply pipe, water spray guide plates, a water mist baffle, aspray pipe and a water receiving tank of the spray pipe, the spray pipe communicates with the water supply pipe, nozzles are arranged on the spray pipe and face the water spray guide plates, the waterreceiving tank is located below the water spray guide plates, and the water mist baffle is provided with blades at certain gaps. According to the internal circulation lampblack purifier, the coolingdevice is arranged, so that the temperature of discharged gas is effectively reduced, high temperature steam in the discharged gas is eliminated, and the influence of the high-temperature steam on theindoor environment is prevented.

Description

technical field [0001] The invention relates to an oil fume purifier, in particular to an internal circulation type oil fume purifier for indoor use. Background technique [0002] At the moment when the smog is cloudy and the virus is raging, people are looking forward to breathing good air. According to scientific analysis, harmful gases emitted by catering (including hotel catering and home catering) are one of the important factors affecting air pollution. In order to control the emissions of catering to the atmosphere, although strict regulations and measures have been continuously adopted at the policy level, due to the lack of technical means, the degree of air pollution has not been fundamentally improved. [0003] In order to meet the needs of the public social environment as well as the needs of people's lives, a circulation type range hood or an internal circulation type range hood is proposed in the prior art, which removes oil fume, peculiar smell and Harmful g...

AI Technical Summary

Problems solved by technology

Although many existing patents have basically realized the pollution-free discharge of catering and cooking, there are still many deficiencies in the purification effect. In particular, although the gas is purified during the purification process, the temperature of the discharged gas is high and has not been obtained. Effective cooling, when the gas returns to the room, it will cause the indoor temperature to rise and a large amount of water vapor to overflow, which will cause discomfort to the cooking operators, especially in the hot summer
