Oil fume purification method

Abstract

The present invention relates to an oil fume purification method. The equipment used by the method comprises a gas collection hood, an oil fume channel, an atomizer, a heating ring, a water pipe, a cone capturer, a motor, an adsorption net, active carbon, a fan, a gas dissolving pump, a filter, an electrode plate, an ultraviolet lamp tube, a liquid storage device, a photocatalyst, a capture liquid, a frame, a bracket, a grid, a vibrator, an outer ring and a silk screen. According to the present invention, the method is based on the physical and chemical characteristics of oil fume; the gasification capture liquid mists with characteristics of fine particle size and uniform distribution are generated through the gas dissolving pump atomization technology, and are mixed with the oil fume soas to adsorb the oil fume onto the gasification capture liquid mist particles, the oil fume mixed with the gasification capture liquid mist is captured into the aqueous solution through the spraying technology, and the oil fume captured into the solution is degraded through the photocatalytic and electrocatalytic synergistic oxidation method; and with the oil fume purification method, the pollution on the external environment is avoided, the healthy and clean environment can be provided for the food processing worksite, and the pollution on the surrounding air environment by the oil fume diffusion cannot be generated.

Description

technical field [0001] The invention relates to a method for purifying oil fume, which belongs to the technical field of environmental protection. Background technique [0002] Catering oil fume widely exists in households and kitchens of catering industries. Because oil fume contains a variety of toxic chemical components, it will damage people's respiratory system and immune system, and has become a potential hazard to the health of cooks and other public health. [0003] The current main treatment methods for cooking fume are: (1) wet treatment technology, (2) mechanical treatment technology, (3) electrostatic treatment technology, (4) incineration and catalytic treatment technology. Among these methods, except for the "incineration and catalytic treatment method" which is purification treatment, the others all belong to emission control. The emission control method is to capture the cooking fume so that it is not directly discharged into the atmosphere, but the captured...

Problems solved by technology

In this way, the cost of the equipment is high, and the catalytic material will be replaced frequently due to the failure of the catalyst activity during use, the operating cost and maintenance cost are high, and it is not suitable for large-scale promotion
