Purifying method and system of kitchen lampblack and lampblack separator

Abstract

The invention discloses purifying method and system of kitchen lampblack and a lampblack separator and aims to provide a method and a system capable of purifying lampblack generated in kitchens to ensure a clean atmospheric environment and ensure that people obtain clean air. The method comprises the following steps of: collecting the lampblack generated by kitchens into a lampblack separator for lampblack separation with a collision cooling method; and cleaning and dedusting by using a wet dust remover after the lampblack is collected, wherein the cleaning and dedusting processes in the wet dust remover are as follows: an adsorption solution is ejected by using a circulating pump into a high-pressure nozzle arranged above the wet dust remover and sprays downwards into the wet dust remover; the absorption solution is in fully contact and collides with the catadromous lampblack and the lampblack is in secondarily contact with the absorption solution at the bottom of the wet dust remover for further absorbing; the lampblack is heated to 150-160 DEG C; and then the lampblack is discharged into the atmosphere through a chimney by using a draught fan.

Description

technical field [0001] The invention relates to a method for purifying cooking fume, a purification system and a fume separator. Background technique [0002] The fuel used in the kitchen is generally pipeline gas, liquefied petroleum gas, natural gas, etc. When these fuels are burned, due to various reasons such as gas impurities, incomplete combustion is formed, and some harmful substances are released and generated, such as: carbon monoxide, nitrogen oxides, sulfides, water vapor and inhalable particulate matter. These combustion products are discharged into the air and spread around, which will cause serious air pollution. At the same time, a large amount of volatile animal and vegetable oils are mixed in the smoke of the kitchen, and they diffuse in the air together with the heat of cooking and the harmful substances released by incomplete combustion. Since the residual oil and the particles produced during incomplete combustion will be adsorbed together, under the ac...

AI Technical Summary

Problems solved by technology

The existing equipment does not have a purification device, only a simple grid and a residual oil box to cut off the residual oil. During the cleaning of the equipment, the residual oil and the use of various types (strong alkali) cleaning agents and a large amount of cleaning wastewater are washed away. If discharged into the sewer, it will cause blockage of the sewer

Moreover, due to the use of forced exhaust, the indoor and outdoor air vortex is caused, and the carbon particles and dust generated by incomplete combustion cause secondary pollution to indoor food and utensils.
