Gas desulfurizer and preparation method thereof

Abstract

A gas desulfurizer is prepared from the following raw materials by weight: 100-120 parts of bamboo charcoal, 30-34 parts of sodium phosphate, 3-4 parts of sodium dodecyl benzene sulfonate, 12-14 parts of sodium montmorillonite, 3-4 parts of aluminum sulfate, 8-10 parts of sodium metasilicate, 28-40 parts of edible mushroom culture materials, 20-24 parts of dandelions, 10-12 parts of chrysanthemum, 3-4 parts of sodium dodecyl sulfate, 4-5 parts of auxiliary agents, and a proper amount of water. By using edible mushroom culture materials, dandelions and chrysanthemum to process active carbon, the desulfurizer of the invention not only can adsorb sulfur, carbon, black smoke and the like, but also is environment-friendly, energy-saving, and antibacterial; by using sodium montmorillonite, the desulfurizer of the invention is good in adsorptivity, good in caking property, and good in catalysis, and saves active carbon; by using sodium phosphate and sodium metasilicate, the desulfurizer of the invention can realize rapid desulfurization; The desulfurizer of the invention is suitable for desulfurization and decarburization of natural gas, flue gas and the like.

Description

technical field [0001] The invention relates to a desulfurizing agent, in particular to a gas desulfurizing agent and a preparation method thereof. Background technique [0002] At present, there are three main methods of flue gas desulfurization agent: one is the combustion sulfur fixation method, which is to add a certain amount of sulfur fixer to the coal, so that the sulfur dioxide generated during the combustion of coal will react with the sulfur fixer, and the sulfate will be discharged together with the slag. , this method is more costly. Another method is wet desulfurization, which mainly adopts spraying method and uses alkaline aqueous solution to absorb sulfur dioxide in flue gas. The land area is large, and the requirements for equipment anti-corrosion are high. Another method is activated carbon adsorption. This method has a short service life of activated carbon, complex regeneration, low desulfurization efficiency, large water consumption for washing, easy to...

Problems solved by technology

Another method is wet desulfurization, which mainly adopts spraying method, and uses alkaline aqueous solution to absorb sulfur dioxide in flue gas. Large area, high requirements for equipment anti-corrosion

Another method is the activated carbon adsorption method, which has a short service life of activated carbon, complicated regeneration, low desulfurization efficiency, large water consumption for washing, easy to cause secondary pollution, and high price of activated carbon, which increases the cost.

[0003] There are two main ways to remove NO and NO2 from flue gas. One is to reduce NO and NO2, such as using ammonia (NH3) as a reducing agent to reduce it to nitrogen. It is necessary to continuously adjust NH3 according to the operating load of the boiler. The amount of injection and the location of injection to ensure that NH3 is injected at the optimum temperature, this method has high operating costs; the other is to convert it into nitrate by oxidation, so as to achieve the purpose of removing NO and NO2
