Abstract

The invention discloses a coal-fired power plant flue gas sulfur dioxide catalytic desulfurization production and technical flow and application of catalyst for coal-fired power plant flue gas sulfur dioxide catalytic desulfurization. The invention has high desulfurization rate, is stable and is easy to grasp, can recycle and use the sulfur dioxide and turn the harm into benefit to create huge economic benefits for coal power enterprises. The catalytic desulfurization production and technical flow are applications of the catalyst in practice. A catalytic desulfurization device comprises a supply system for producing catalyst and a catalyst distributing tank, a raw gas processing system consisting of a secondary dedusting and pressurizing fan and a heat exchanger, and dual-body catalytic towers arranged in a core device and mutually switched through an appliance and control system and a transfer switch, and the uniformity of a catalytic system and a cycling system is formed by shifting operation; and after desulfurization, a sulfur dioxide saturated sulphate liquid becomes an industrial material, thus achieving the purpose of changing wastes into values. The technology is applicable for the environmental protection of various coal-fired enterprises.

Description

Technical field: [0001] The present invention mainly relates to the fields of environmental protection, energy saving, emission reduction, transformation of economic growth mode, etc. The present invention has three parts: 1. SO 2 , the invention of the catalyst, and the production and supply system of the catalyst; 2. The flue gas sulfur dioxide in coal-fired power plants, the catalytic desulfurization production and process system; 3. The sulfate solution recovered after desulfurization, the purification and product production system. (This system is provided by Jiangsu Complete Chemical Equipment Co., Ltd.). Background technique: [0002] Sulfur dioxide SO 2 It is the first of the top ten pollution hazards in the world. Almost all industrial coal, gas and fuel oil produce sulfur dioxide SO 2 , but the largest emitter is coal-fired power plants. At present, limestone / gypsum wet desulfurization technology, which is widely used in international and domestic coal power indu...
