Clean fired coal saving agent

Abstract

The invention provides a clean fired coal saving agent with the effects of sulfur fixation, dust fall, heat increment and coal saving which is prepared and produced by industrially produced waste liquid and waste residues and chemical and mineral product raw materials. The clean fired coal saving agent is divided into two forms, namely a liquid product and a powder product; the liquid product is obtained by dissolving sodium nitrite, potassium nitrite, potassium nitrate, sodium nitrate, sodium sulfonate and sodium dodecyl benzene sulfonate into mixed liquid of paper making black liquid, alcohol waste liquid and fired coal fume water film dust removal and desulfurization alkali regeneration fluid; and the power product is obtained by absorbing and preparing the liquid product by utilizing hot fired coal slag, then allocating the chemical and mineral product raw materials and finally uniformly mixing, drying and crushing. The invention achieves cyclic resource utilization of industrial wastes, effectively solves the difficult problems of complete control of fired coal pollution and paper making and alcohol waste liquid pollution, has the advantages of innocuity, odorless, no three-waste emission, no increased investment and convenient operation and can use the device required not to be improved, save the coals per ton by 20-50 yuan and be used for all industrial and civil fired coals.

Description

Technical field: [0001] The invention relates to a coal-burning cleaning and coal-saving agent with high-efficiency sulfur-fixing, dust-reducing, heat-increasing and coal-saving prepared by using papermaking black liquor, alcohol waste liquid, coal-fired flue gas water film dedusting and desulfurization waste liquid, and waste residue. Background technique: [0002] my country is rich in coal resources and is the world's largest coal producer and coal consumer. Since my country's economic construction is an extensive development model with high energy consumption and high pollution, it has paid a huge price for energy resources while growing my country's economy. The cost of pollution. In order to curb this trend, and according to the specific national conditions of the vast number of small and medium-sized coal-fired enterprises in our country, develop high-efficiency, clean coal-saving agents, especially the research, development and utilization of a large amount of waste l...

Problems solved by technology

In order to curb this trend, and according to the specific national conditions of the vast number of small and medium-sized coal-fired enterprises in our country, develop high-efficiency, clean coal-saving agents, especially the research, development and utilization of a large amount of waste liquid and slag produced by industrial production, mainly black paper produced by paper mills. The waste liquid produced by the production of liquid and alcohol, the waste liquid produced by the dust removal and desulfurization of coal-fired flue gas, and the production of coal slag to prepare coal-fired clean coal-saving agents are a small investment with quick results and high benefits, and can produce a huge The technological invention of the new technology industrial group that treats waste and turns waste into treasure has not yet seen the use of papermaking black liquor, alcohol waste liquid, and coal-fired flue gas dust removal and desulfurization waste liquid for production and preparation of coal-fired clean and coal-saving agent technical report
