Method for producing smoke-prevention, dust-control and energy saving combustion improver

Abstract

A method for producing a smoke-eliminating, dust-removing, and energy-saving combustion-supporting agent, comprising the steps of: a) mixing 4.0-6.0 parts by weight of potassium chloride, 3.0-4.0 parts by weight of magnesium chloride, and 4.5-5.5 parts by weight of Fe 2 o 3 After crushing and fine grinding, mix, place in a reaction pot, add water, and stir for reaction; b) crush 6.0-8.0 parts by weight of ammonium nitrate, place in another reaction pot, add water, stir for reaction, and a ) the last reactant is added, then mixed, stirred and reacted; c) 25-30 parts by weight of heavy calcium carbonate is pulverized, placed in a reaction pot, added 0.5-1.0 parts by weight of nitric acid and water, stirred, mixed After dehydration, calcium nitrate is generated, and then mixed with the reactant obtained in step b), reacted, dried, added rare earth quartz barite carbonate, after the reaction, added kaolin ore and mixed, and the reaction is complete An industrially usable combustion accelerant is obtained. The combustion accelerant obtained by the invention can play the role of catalysis and heat release in the combustion of coal, and at the same time has a certain effect of fixing sulfur, which can reduce the pollution to the environment.

Description

Technical field: [0001] The invention belongs to the field of chemistry, in particular to fuels in the coal industry, in particular to a method for manufacturing a smoke-eliminating, dust-removing, energy-saving and combustion-supporting agent. Background technique: [0002] my country is a big country that consumes coal. There are about 400,000 boilers that consume 300 million tons of coal each year, more than 110,000 industrial kilns, more than 200 million tons of coal per year, and more than 200 million tons of civilian coal. , the boiler efficiency is low, the energy consumption is large, the exhaust gas discharge exceeds the standard, and the air pollution is serious. At present, in order to reduce the energy consumption of coal-fired boilers and reduce the impact of coal-fired boilers on environmental pollution, it is necessary to reform Coal uses fuel oil or gas, but it requires huge capital investment, and high operating costs after transformation. In the prior art, in...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in the prior art, in order to improve the combustion efficiency of coal-burning, a combustion-supporting agent is usually used, and the described combustion-supporting agent comprises potassium permanganate, sodium salt, iron oxide, manganese dioxide, but high Potassium manganate is a strong oxidizing agent, which has low safety and high cost, and contains a large amount of sodium salts. The combustion-supporting agent of iron oxide and manganese dioxide is easy to coke, the combustion-supporting effect is not good, and it will cause secondary pollution. The present invention is The technical solution adopted to solve the above-mentioned technical problems in the prior art is to provide a method for manufacturing a smoke-eliminating, dust-removing, energy-saving combustion-supporting agent, wherein, the manufacturing method of the combustion-supporting agent includes the following steps:
