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.

Example Embodiment

[0010] A gas desulfurizer made of the following parts by weight (kg) of raw materials: bamboo charcoal 110, sodium phosphate 32, sodium dodecylbenzene sulfonate 3.5, sodium montmorillonite 13, aluminum sulfate 3.5, and sodium phosphate 9 , Edible fungus culture material 34, dandelion 22, chrysanthemum 11, sodium lauryl sulfate 3.5, adjuvant 4.5, appropriate amount of water; the adjuvant is made of the following parts by weight (kg) of raw materials: montmorillonite powder 10, Titanium dioxide 1, activated carbon 4, medical stone 2, ammonium chloride 3, flour 5, appropriate amount of water; its preparation method is to add flour into water, heat and stir into a paste, then add other ingredients to make a mud, and then send it to calcination It is calcined in a furnace at 450-500°C for 4-5 hours, and after cooling, it is pulverized into 100-150 mesh powder.

[0011] The preparation method of the gas desulfurizing agent includes the following steps: crushing sodium-based montmorillo...

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...
