It is a kind of environmentally friendly washing equipment , which is divided into three categories according to the shape of gas-liquid contact. One type is a plate tower in which a gas is relaxed in a liquid phase in a liquid phase, a bubble absorption tower, a stirring bubbling absorption tower; and the other is an ejector, a venturi, and a spray tower in which a liquid is loosely suspended in a gas phase; The three types are a packed absorption tower and a falling film absorption tower in which a liquid is in contact with a gas phase in a film-like motion. According to the practice summary, the 2008 Beijing Olympic rowing paint extraction waste gas purification tower supplier, the biological purification tower, the biological purification principle, the layer filtration adsorption purification, is another common equipment in the exhaust gas purification tower.
The gas-liquid two-phase activity in the tower can be reversed or co-current. Generally, the countercurrent operation is adopted, and the absorbent participates in the top-down activity at the top of the tower, and contacts the gas moving from the bottom to the top, and the liquid absorbing the absorbed matter is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower.
The exhaust gas purification tower should have the following basic requirements:
气体 Gas and liquid in the tower should have satisfactory contact area and contact time.
◇ Gas and liquid have correspondingly strong disturbances, reducing mass transfer resistance and absorbing energy.
◇ The operation plan is wide and the operation is stable.
◇ Low resistance and low energy consumption.
◇ Have satisfactory mechanical strength and corrosion resistance.
◇ The structure is simple, easy to make and overhaul.
