The exhaust gas purification tower is a device that realizes an absorption operation. According to the gas-liquid contact morphology, it is divided into three categories. The first type is a plate tower in which a gas is dispersed in a liquid phase, a bubble absorption tower, and a stirring bubble absorption tower; the second type is an ejector, a venturi, and a spray in which a liquid is dispersed in a gas phase in a droplet form. The third type is a packed absorption tower and a falling film absorption tower in which the liquid is in contact with the gas phase in a film-like motion. As a domestic professional environmental protection professional construction three-level qualification of exhaust gas purification tower supplier, Wuxi Reid Environmental Protection Equipment Co., Ltd. based on the practice summary, developed a biological purification tower, using biological purification principles, layer filtration adsorption purification, is the exhaust Another unique device in the purification tower.
The flow of gas and liquid in the tower can be reversed or cocurrent. Usually, a countercurrent operation is employed, in which the absorbent is fed from the top to the bottom, and is in contact with the gas flowing from the bottom to the top, and the liquid absorbing the absorbent is discharged from the bottom of the column, and the purified gas is discharged from the top of the column.
The exhaust gas purification tower should have the following basic requirements:
Gas and liquid in the tower should have sufficient contact area and contact time.
◇ Gas and liquid have strong disturbances, reducing mass transfer resistance and improving absorption efficiency.
◇ Wide operating range and stable operation.
◇ Low resistance and low energy consumption.
◇ Have sufficient mechanical strength and corrosion resistance.
◇ Simple structure, easy to manufacture and overhaul.
