Stainless steel desulphurization deduster factory
The large desulfurization unit of flue gas desulfurization is called desulfurization tower, and the small desulfurization and dust removal device used for flue gas desulfurization of coal fired industrial boiler and kiln is called desulfurization dust collector. In the desulfurization tower and desulfurization dust collector, the flue gas containing SO2 should be contained, and the chemical absorption of SO2 in the flue gas should be carried out. In order to strengthen the absorption process, improve the desulfurization efficiency, lower investment and operating cost of equipment, desulfurization tower and
(1) between the gas and liquid has a larger contact area and the contact time;
(2) between the gas and liquid absorption disturbance, low resistance, high absorption efficiency of SO2;
(3) stable operation, must have the appropriate operating flexibility;
(4) when the pressure drop to flow through the small
(5) has the advantages of simple structure, convenient manufacture and maintenance, low cost, long service life;
(6) no scaling, no blockage, abrasion resistance, corrosion resistance;
(7) low energy consumption and no two pollution.desulfurization precipitatorshould meet the basic requirements of the following.
Working principle:
SO2 absorption and purification process, the treatment is low concentration of SO2 flue gas, considerable amount of flue gas, requiring instantaneous continuous efficient purification of flue gas. Therefore, the chemical reaction of SO2 should be very fast, and their conversion coefficient is larger, and the reaction occurs in the membrane. Therefore, it is more suitable to adopt the absorption tower with the vapor phase as the continuous phase, the high turbulence level and the large phase interface as the desulfurization tower and desulfurization dust collector. Usually, spray tower, packing tower, spray tower, plate tower, Venturi absorption tower can meet these requirements. The spray tower is one of the most widely used type of desulfurization tower, spray tower has the advantages of simple structure, has the advantages of mature technology and reliable, widely used in large power plant, control of small and medium scale low sulfur gas; for the treatment of high sulfur gas, the nonferrous metals industry in pneumatic emulsifying desulfurization tower, multi layer spray tower.
