Exhaust gas purification tower by gas-liquid contact form is divided into three categories. The first category is gas bubble-shaped dispersion in the liquid phase of the plate tower, bubbling absorption tower, stirred bubbling absorption tower; the second is liquid droplets dispersed in the gas phase ejector, venturi, spray Tower; the third is the liquid film-like movement with the gas phase contact with the packing absorption tower and falling film absorption tower. 2008 Beijing Olympic rowing paint exhaust gas purification tower suppliers, according to the practice summary, research and development of biological purification tower, the principle of biological purification, layer filtration adsorption purification, exhaust gas purification tower is another unique equipment.
Gas-liquid tower two-phase flow can be countercurrent flow can also be. Usually countercurrent operation, the absorbent to the top of the tower to join the top-down flow, and the gas flows from the bottom up, absorbing the absorption of liquid from the bottom of the discharge, the purified gas from the top of the tower.
Exhaust gas purification tower should have the following basic requirements:
Waste gas purification tower is generally made up of draught fan, packing layer, demister, circular watering pipe, circulating water channel, etc.
Currently, waste gas purification tower has been successfully used to deal with spraying waste gas, printing waste gas, chemical waste gas, electronic waste gas, medical waste gas, asphalt waste gas, mechanical exhaust, sewage waste gas, etc. And it also has a great success in meeting the national discharge standard. At the same time, it removes odour and improves the environment. It is especially suitable for the waste gas which is of low dust capacity, low concentration and great peculiar smell.
This machine aims at separating gas from the contaminant and translating into innocuous substance and then cleaning gas. The waste gas intakes to the purifying column through the air hose, after packing, the waste gas and absorption liquid are completely contacted and have a neutral reaction. After purified, the waste gas discharges into the environment after demisting and dehydration. Its motivation is draught fan.
