Problems solved by technology

However, when the height of the desulfurization tower is limited and the increased spray layer cannot meet the required liquid-gas ratio, a new desulfurization tower needs to be built, which will increase the investment of the power plant
At the same time, increasing the liquid-gas ratio of the desulfurization system will increase the energy consumption of the system, increase the power consumption rate of the plant, and reduce the economical efficiency of the power plant operation.

Abstract

The invention provides a desulphurization catalysis improved synergist. The synergist is prepared from the following raw materials by weight: 10 to 15 parts of benzoic acid, 6-14% of adipic acid, 10-18% of magnesia, 7-16% of magnesium sulfide, 20-26% of calcium carbonate, 20-26% of calcium chloride, 2-5% of manganese sulfate, 2-5% of potassium permanganate, 3-6% of sodium hypochlorite, 2-5% of polysiloxane and 3-6% of silicon dioxide. The synergist provided by the invention can improve desulphurization efficiency, reduce the number of operating circulating slurry pumps and lower a liquid-gas ratio in desulphurization operation, thereby achieving the purposes of energy conservation and reduction in operation cost.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a desulfurization catalytic improvement synergist. Background technique [0002] At present, the existing pollutant removal equipment in thermal power plants basically meets the emission standards, but the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)" puts forward higher requirements for "ultra-clean" emissions, so the use of existing The coordinated removal of multiple pollutants by flue gas treatment equipment has good timeliness and economy. In order to meet the increasingly stringent environmental protection requirements, most power plants increase the number of desulfurization tower spray layers to increase the liquid-gas ratio of the desulfurization tower, thereby improving the desulfurization efficiency. But when the height of the desulfurization tower is limited, if the increased spray l...
