Evaporation plant for magnesium chloride

Abstract

The invention relates to a device for evaporating magnesium chloride, which belongs to the equipment for evaporating bittern. The device for evaporating magnesium chloride comprises a heating furnace which is sequentially connected with an evaporating and feeding tank and a heating evaporating tank by pipelines; a plurality of heated tubes are arranged in the heating furnace and the heated tubes are communicated with the bottom of the evaporating and feeding tank by a feeding pipeline; the heating and evaporating tank is communicated with the evaporating and feeding tank by a steam communication pipeline; the steam in the evaporating and feeding tank can enter the heating and evaporating tank by the steam communication pipeline; a steam chamber is arranged in the heating and evaporating tank and the steam chamber can heat the bittern in the heating and evaporating tank; the arrangement of the steam chamber ensures that the heating and evaporating tank can carry out secondary utilization of the heat energy of the steam in the evaporating and feeding tank and the arrangement of the heated tube in the heating furnace greatly increases the heated area of the bittern, thus improving the utilization rate of the heat energy.

Description

technical field [0001] The invention relates to a magnesium chloride evaporation device, which belongs to brine evaporation equipment. Background technique [0002] Nowadays, most of the extraction of magnesium chloride by evaporation in the society uses the original cauldron evaporation method. This method has the following disadvantages: 1. The combustion of coal, natural gas and other energy sources directly heats the cauldron, and the waste gas is directly discharged into the air, taking away a large amount 2. The water vapor generated during the evaporation process is directly discharged into the air. This water vapor contains a large amount of volatiles of toxic components, causing environmental pollution; 3. Using the large pot evaporation method, brine Many components in the oil are precipitated and adhered to the wall of the pot, resulting in a decrease in the thermal conductivity of the pot, and the pot is easily burned out. In order to remove the adherents, the me...

Using the large pot evaporation method, brine Many components in the oil are precipitated and adhered to the wall of the pot, resulting in a decrease in the thermal conductivity of the pot, and the pot is easily burned out. In order to remove the adherents, the method of manually scraping the pot is used, which increases labor intensity, causes waste of personnel, and is not conducive to large-scale Production
