Desulfurization tower (as the name suggests, for the desulfurization tower) for industrial waste gas desulfurization equipment to deal with the majority of tower equipment, that is, the desulfurization tower. The desulfurization tower initially in the application of granite masonry is the most widely used, the water film desulfurization and dust removal principle, also known as granite water film desulfurization dust remover, or a granite water film desulfurization dust remover. The advantages are easy maintenance, and the effect of dust removal and desulfurization (denitrification) can be achieved through the preparation of different dust removal agents. Now with the development of FRP technology, the desulfurization tower is gradually replaced by glass fiber reinforced plastic. Compared with the granite desulfurization tower, low cost, easy processing, no rust and light weight, so it has become the development trend of the desulfurization tower in the future. In addition 316L stainless steel corrosion resistance, high temperature resistance, wear resistance of the three major advantages, but also one of the important trends in the development of desulfurization tower. After years of development has been improved, the desulfurization tower venturi type, written swirl plate, vortex column type, float type, plate type, pneumatic emulsifying type and other types of equipment, technology matures, each has advantages and disadvantages, according to their own need to choose different types of enterprises.

Desulfurization requirements of desulfurization tower
Flue gas desulfurization desulfurization equipment is a large desulfurization tower, and used for coal-fired industrial boiler and furnace flue gas desulfurization of small desulfurization and dust removal device, known as the desulfurization dust. In the desulfurization tower and desulfurization precipitator, should contain SO2 of flue gas, the flue gas in the chemical absorption of SO2. In order to strengthen the absorption process, improve the desulfurization efficiency, reduce the equipment investment and operating costs, glass steel desulfurization tower and glass steel desulfurization precipitator should meet the following basic requirements:
1 there is a large contact area between the gas and liquid and the contact time;
2 the gas-liquid disturbance is strong, the absorption resistance is small, and the absorption efficiency of SO2 is high;
3 stable operation, to have the appropriate operating flexibility;
4 air flow through the pressure drop to be small;
5 simple structure, easy manufacture and maintenance, low cost and long service life;
6 no scale, no clogging, wear resistance, corrosion resistance;
7 low energy consumption, no two pollution.
The main advantages of the field application of the desulfurization tower:
Room temperature operation, avoid due to welding and other traditional crafts of thermal stress and deformation, also to avoid the damage of the two parts; another simple construction process, the repair process of on-site operation or equipment and local repair; plasticity micava materials, wear resistance and anti scouring ability itself is excellent, is the application of the ideal technology to solve the problem.
