Dewatering industrial stove for carnaillite hydrous chloromagnesite

Abstract

The invention belongs to the chemical machinery field, particularly relating to a dehydration industrial furnace of carnallite plus bischofite. The furnace comprises a coal injection machine, a dust catcher, a furnace body, a smoke-steam recovery device, etc., wherein, a combustion chamber, one to four heating chambers communicated with one another in series, and one to two preheating chambers arearranged in the furnace body, the coal injection machine is communicated with the combustion chamber, the combustion chamber is communicated with the heating chambers, one to four reaction kettles are disposed in the heating chamber, one to four preheating kettles are arranged in the preheating chambers, fire-separating walls are disposed in the heating chamber and the preheating chambers, the preheating chambers are connected with the dust catcher, and a tail gas recovery pipe is communicated with a sealing cover and is connected with a fan. The dehydration industrial furnace has the advantages of simple structure, convenient operation, effectively controlling environmental pollution, eliminating potential safety hazards, meeting the process requirements, stable product quality and low energy consumption.

Description

1. Technical field: [0001] The invention belongs to the field of chemical machinery, and in particular relates to an industrial furnace for dehydrating carnallite and cholerite. 2. Background technology: [0002] my country is rich in magnesium resources, and the reserves of Chaerhan Salt Lake in Qinghai alone are as high as 1.67 billion tons, mainly bischofite (MgCl 2 ·6H 2 O) exists in the form and is enriched in natural carnallite (KCl MgCl 2 ·6H 2 O). In the existing technology, carnallite and bischofite are mixed, put into a large pot for heating, and after being heated to a dehydrated state, the dehydrated product of carnallite bischofite is obtained. Although this method is simple, However, its environmental pollution is large, often causing pot collapse accidents, large safety hazards, unstable product quality, and high energy consumption. 3. The content of the invention [0003] The purpose of this invention is to provide a kind of dehydration industrial furn...
