Impinging stream gas purification system

Abstract

The invention discloses an impinging stream gas purification system, including a plurality of purification unit devices at intervals in order. Two adjacent purification unit devices are communicated through a first pipeline; each purification unit device comprises an upright impinging flow type gas-liquid reaction chamber, an inverted impinging flow type gas-liquid reaction chamber and a second pipeline for communication; a convolute liquid jet pipe inserts into a forward flow channel and a reverse flow channel in the impinging stream type gas-liquid reaction chamber; the first pipeline between the two adjacent purification unit devices is provided with an ultraviolet lamp; the end of the inverted impinging flow type gas-liquid reaction chamber in each purification unit device is also provided with a self-cleaning catalytic membrane; the self-cleaning catalytic membrane includes a stainless steel mesh and a titanium dioxide layer plated on the stainless steel mesh; the purification unit device at the extreme end is orderly provided with a gas-liquid separation chamber; and the gas-liquid separation chamber is provided with a gas-liquid separation guide plate and a gas-liquid separation membrane. The system can carry out high efficiency purification treatment on gas in a large amount of and containing various ingredients.

Description

technical field [0001] The invention relates to the field of air purification equipment, in particular to an impinging flow gas purification system. Background technique [0002] Nowadays, the air quality in cities is getting worse and worse, and people's demands for improving air quality are becoming stronger and stronger. People are concerned about pm2.5 (particulate matter), that is, the aerodynamic equivalent diameter in ambient air is less than or equal to 2.5 μm (micron) particulate matter, also known as fine particulate matter. The higher the value of pm2.5, the more serious the air pollution. However, in daily industrial production, a large number of gases with different components (including polluting solid particles, dust, organic pollutant gases, etc.) are often discharged to cause air pollution; [0003] There are three types of air purifiers classified according to the purification principle: [0004] 1. Filtration and adsorption type: use porous filter mater...

Problems solved by technology

) for degradation and removal; but it still has the following technical defects: when the gas film and the electrostatic purification structure are used in combination, the wind resistance is relatively large, and it is impossible to efficiently purify the gas with a large amount of gas, and the processing capacity Very small, there are still a lot of pollutants in the air that cannot be purified, and its purification efficiency is very low

This scheme has the following deficiencies: 1. Only one gas-liquid contact is carried out for the gas to be treated, and deep and multi-wave gas-liquid contact cannot be carried out

2. Only one kind of liquid can be used as the gas-liquid contact medium, and it is not possible to react and separate and enrich gases containing many different components

3. This technical solution cannot form a highly efficient photocatalyst structure, so the efficiency of chemical reactions to gases containing different chemical components is very low
