Abstract

Disclosed is an apparatus for low-temperature continuous conversion of potassium chloride to heating steam and production process, wherein the apparatus includes a rectangular reaction tank having an intake port of steam, potassium chloride and sulfuric acid, a hydrogen chloride gas outlet, a temperature gauge port and a stirring paddle port on the roof board, a potassium hydrogen sulfate outlet at the center of the right side wall, a drainage port on the right side bottom, and a steam raw material pipe line. The production process comprises charging steam, potassium chloride and sulfuric acid successively into the reaction tank, wherein the weight ratio of potassium chloride and sulfuric acid is 1 : 1.2-1.7, controlling temperature in reaction area with steam amount, stirring the reaction mass with the stirring paddle, and finally discharging potassium hydrogen sulfate end product continuously.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizer production, in particular to equipment and a production process for potassium chloride low-temperature continuous conversion steam heating, and the produced potassium bisulfate is one of the main raw materials for producing NPK compound fertilizer. Background technique [0002] In the production of NPK compound fertilizer, as the raw material of potassium element, it is necessary to convert potassium chloride and sulfuric acid into potassium bisulfate. The traditional conversion process is the Mannheim furnace method. This method is potassium chloride and sulfuric acid at 500-600 ° C Reaction at high temperature. This kind of process equipment has a large investment and high energy consumption. It will be changed to a low-temperature batch conversion process in the future. The reaction equipment used in this process is an enamel reactor, and its structure is as follows figure 1 shown....
