Exhaust gas purification tower
The utility model relates to an exhaust gas purifying device which is made of glass fiber reinforced plastic material. There are three types according to the gas-liquid contact morphology. The first is the gas dispersion in liquid phase plate tower, bubble absorption tower, bubble absorption tower to form bubbles; the second is the liquid dispersion in the injector, venturi tube, spraying tower gas phase to liquid droplet; third kinds of liquid film in motion and gas phase contact filler the absorption tower and the falling film absorption tower. The 2008 Beijing Olympic rowing paint waste gas purification tower supplier, Shanghai najule environmental protection science and technology limited company according to the practice, developed a biological purification tower, the principle of biological purification, layers of filtration and adsorption purification, waste gas purification is a special equipment in the tower.
Exhaust gas purification tower structure
The flow pattern of gas-liquid two-phase flow in glass fiber reinforced plastic waste gas purification tower can be counter current or parallel flow. Countercurrent operation is usually adopted, the absorber is added to the top of the tower to flow from top to bottom, and the gas flowing from the bottom to the top is contacted.
Exhaust gas purification tower should have the following basic requirements
1 there should be enough contact area and contact time between gas and liquid.
2 gas-liquid two has strong disturbance, reduce mass transfer resistance and improve absorption efficiency.
3 wide operating range, stable operation.
4 equipment resistance, low energy consumption.
5 with sufficient mechanical strength and corrosion resistance.
6 simple structure, easy to manufacture and maintenance.
