Organic solvent absorption tower is also a tower used more in absorption operation. Its main components are supporting grid plate, spherical packing, retaining screen, foam separator, liquid nozzle, etc. When the operation is used, a certain number of cylindrical fillers are placed on the grid plate. The gas is introduced from the bottom of the tower, and the liquid is sprayed from the top of the tower through the nozzle. In packing layer between gas-liquid contact, irregular type fillers greatly increase the gas-liquid contact area to improve the efficiency of purification, considering some of the waste gas of high temperature gas, equipment type packing can be divided into high temperature resistant ceramic packing, not high temperature resistant type pall ring filler, PP material equipment and glass fiber reinforced plastic material is not high temperature resistant, but there are anti-corrosion performance, The choice of equipment material is based on the temperature and corrosion of the exhaust gas.
Operating principle of organic solvent absorber
The waste gas is transported to the organic solvent recovery tower through the pipeline. In the organic solvent absorption tower, the waste gas enters from the bottom of the tower and fully contacts with the organic solvent absorption liquid sprayed from the top of the tower, so as to achieve the purpose of purification. The bottom of the organic solvent absorption tower is provided with a packing supporting plate, and the packing is placed on the supporting plate in a chaotic manner. The packing plate is installed above the packing to prevent it from being blown by the updraft. The organic solvent absorbent is sprayed onto the packing from the top of the tower through the liquid distributor and flows down the packing surface. Gas is sent from the bottom of the tower, distributed by the gas distribution device, and the liquid is continuously counter-current through the gap of the packing layer. On the packing surface, the gas-liquid two phases are in close contact for mass transfer. Considering that when liquid flows downward along the packing layer, sometimes wall flow phenomenon will occur, wall flow effect causes the gas-liquid two phases in the packing layer distribution is not uniform, so that the mass transfer efficiency decreases. We adopt the method of dividing the packing layer in the organic solvent absorption tower into two sections. The redistribution device is set in the middle of the tower. After redistribution, it is sprayed on the lower packing to make the absorption surface larger to achieve the purpose of absorbing dust and waste gas.
Organic solvent absorption solution is based on gas composition analysis, classifying the chemistry of organic matter, such as methanol can be soluble in water, methyl mercaptan, soluble in water and can react with sodium chloride, potassium permanganate, etc the chemical properties such as absorption liquid, to select for some of the chemical composition is not a single we usually take according to certain proportion of exhaust gas mixture to absorb, Organic solvent absorber is suitable for treating the waste gas with high concentration and large air volume. According to the specific treatment volume, the organic solvent absorber can be designed to increase the diameter or spray series to improve the treatment effect. Suitable for: chemical industry, dyestuff, mine smelting, electroplating, plastic industry and other dust removal and deodorization.
Organic solvent absorption tart point
1, excellent corrosion resistance, can resist almost all inorganic media and most organic solvents.
2, small resistance, high purification efficiency, not easy scaling, non-toxic.
3, light weight, small volume, modified model product absorption and liquid storage structure, installation, maintenance is more convenient.
4, the price, the cost of economic benefits.
