Method and equipment for preparing fuel from household garbage for suppressing dioxin

The invention relates to a method and equipment for preparing fuel from household garbage for suppressing dioxin. The method comprises the following steps of: introducing a heat source into vertical heat treatment equipment by using high-temperature gas as the heat source to ensure that the heat source is in direct contact with the household garbage in the vertical heat treatment equipment to cause heat transfer; performing thermal cracking reaction after the raw materials are heated; recovering and utilizing the cracked gas phase product; burning out residues caused by thermal cracking; and introducing high-temperature smoke gas generated by burning into the heat treatment equipment to heat the raw materials. The equipment for preparing the fuel from the household garbage for suppressing dioxin provided by the invention mainly comprises the vertical heat treatment equipment for drying the household garbage and performing thermal cracking on the household garbage, equipment for burning the cracked residues and collection and utilization equipment for the gas phase product. The method and the equipment have the advantages that equipment structure is simple, large-scale, continuity, reclamation and minimization treatment of the household garbage can be realized, and the like.

Method for preparing monopotassium phosphate through feed-grade calcium hydrophosphate

The invention discloses a method for preparing monopotassium phosphate through feed-grade calcium hydrophosphate. The method comprises steps of carrying out conversion reaction on the raw material feed-grade calcium hydrophosphate and phosphoric acid solution, then carrying out extraction reaction with sulfuric acid, filtering so as to obtain filtrate, regulating pH of the filtrate to be 7.1-8.5 with industrial-grade phosphoric acid, then adding potassium carbonate and potassium hydroxide solution into the filtrate for neutralizing, after finishing the reaction, regulating pH to be 8.5-9.5, filtering so as to obtain filtrate, continuously regulating pH of the filtrate to be 4-4.5 through industrial-grade phosphoric acid, regulating the density of the reaction liquor, and after completely dissolving out the crystal, centrifugally drying so as to obtain monopotassium phosphate. The method is simple; the product can meet the requirement of first-grade goods of national industrial standard, the content of monopotassium phosphate is over 98%, and the yield of the product monopotassium phosphate is high, so that the method is applicable to large-scale industrial application; the method lowers the cost of the product by adopting low-cost feed-grade calcium hydrophosphate and returning the dehydration mother liquor back to a reaction kettle for cycle use, and avoids strong corrosion to equipment in the technological process.
