The gas generator is a production facility that converts coal into flammable gas—gas (main components are CO, H2, CH4, etc.). The working principle is: After the coal that meets the gasification process index is selected, the coal gasifier is added into the gas furnace, and the self-produced steam and air mixed gas is blown into the gasifier as the gasification agent.
The exhaust gas treatment of the gas generator can adopt the bag filter + desulfurization tower. Gas furnace exhaust gas treatment desulfurization tower is a wet desulfurization equipment, because it is tower tower name desulfurization tower. Wet desulphurization of producer gas is mainly represented by arsenic-alkali method and tannin extract method, but it requires high technical requirements and requires full-time personnel to maintain and operate. The above two gas furnace desulfurization methods each have their own advantages, and can effectively and completely remove the hydrogen sulfide components in the gas generator gas. At present, desulfurization towers commonly used at home and abroad mainly include spray air towers, packed towers, dual-circuit towers, and jet drum turrets. It is possible to use a spray tower in a gas producer. According to the amount of gas generated, the number of spray layers in the desulfurization tower can be selected. The desulfurization solution medium can be alkali, ammonia, or limestone.
In the desulfurization tower equipment, alkali liquor is used to scrub the SO2 containing flue gas and the SO2 in the flue gas is chemically absorbed. In order to enhance the absorption process, increase the desulfurization efficiency, and reduce the investment in equipment and operating costs, the desulfurization tower should meet the following basic requirements:
(1) There is a large contact area and a certain contact time between gas and liquid;
(2) The gas-liquid interaction is strong, the absorption resistance is small, and the SO2 absorption efficiency is high;
(3) Operation is stable and proper operation flexibility is required;
(4) The pressure drop when air flow passes is small;
(5) Simple structure, convenient manufacture and maintenance, low cost, long service life;
(6) No scaling, no clogging, wear resistance, corrosion resistance;
(7) Low energy consumption and no secondary pollution.
The SO2 absorption purification process deals with low-concentration SO2 flue gas, and the amount of flue gas is considerable, requiring continuous and efficient purification of the flue gas in an instant. Therefore, the chemical reactions that SO2 participates in should be extremely fast. The values ​​of their intramolecular conversion coefficient are large and the reaction takes place within the membrane. Therefore, the absorption tower with a continuous phase, a high degree of turbulence, and a large phase interface is selected as the desulfurization tower. And desulphurization dust collector is more appropriate. In general, spray towers, packed towers, spray towers, tray towers, Venturi absorption towers, etc. can meet these requirements. Among them, the spray tower is one of the most widely used types of desulfurization towers. The spray tower has a simple structure, a mature and reliable process, and is widely used in large-scale power plants to treat small and medium-sized low-sulfur flue gas. For the treatment of high-sulfur flue gas, The non-ferrous industry mainly consists of pneumatic emulsified desulfurization towers and multi-layer spray towers.
