Potassium sulfate co-production compound fertilizer production device and key structure and technological process thereof

Abstract

The invention belongs to the technical field of potassium sulfate production and application, and discloses a potassium sulfate co-production compound fertilizer production device and a key structure and a technological process thereof.The production device comprises an outer shell, an inner shell, a conveying groove, a water tank, a box body, a partition plate and a washing tank, the conveying groove is fixed to the side wall of the outer shell in a penetrating mode, and the water tank corresponds to the bottom of the conveying groove; the box body is located on one side of the conveying groove, the bottom of the box body is fixedly connected with the water tank, the interior of the box body is fixedly connected with the partition plate, and the washing tank is located on one side of the outer shell; the technological process comprises the steps of raw material adding, thermal decomposition reaction, reaction gas treatment, potassium sulfate conveying and potassium sulfate treatment. The potassium sulfate coarse material and generated gas can be separately treated, the gas can be recycled, the reacted potassium sulfate coarse material is convenient to discharge, the cooled potassium sulfate coarse material can be subjected to multi-stage treatment, the production quality of potassium sulfate is ensured, and meanwhile, the production capacity can be improved.

Description

Technical field [0001] The present invention relates to a co-production of potassium sulfate fertilizer production process and apparatus, particularly to an apparatus and Potassium Sulfate and fertilizer production process and critical structures, belonging to the technical field of production of potassium sulfate applications. Background technique [0002] An inorganic salt is potassium sulfate, the formula of K2SO4, as a white crystalline powder, potassium agricultural appearance mostly yellow, hygroscopic potassium small, easy to agglomerate, good physical properties, convenience of administration, is well soluble of potash, the main raw material is a chlorine-free production of nitrogen, phosphorus and potassium of NPK fertilizer, a potassium salt such as potassium various manufacturing, basic material such as potassium persulfate, the glass industry as a supernatant agents, dye industry as intermediates. Perfume industry as additives. The pharmaceutical industry is also used...

AI Technical Summary

Problems solved by technology

[0003] In the patent document "CN104496624A A method and device for producing high-tower nitro compound fertilizer", it reduces the risk of soil acidification after the application of compound fertilizer, and eliminates the defect of crop roots being burned; it does not need to add large-scale equipment. It is enough to carry out simple transformation on the surface, energy saving and emission reduction, which is conducive to large-scale use and promotion, but the production capacity of potassium sulfate is relatively low, which also reduces the corresponding production capacity of hydrochloric acid. The gas produced is difficult to achieve effective treatment

At present, there is still no potassium sulfate co-production compound fertilizer production device and process flow with reasonable and reliable structure, improved production capacity and convenient potassium sulfate subsequent treatment.
