Heating evaporation system for high-level automatic oil supplement alkali liquid concentration

Abstract

The invention relates to an alkali liquid concentration system, and particularly relates to a heating evaporation system for high-level automatic oil supplement alkali liquid concentration. A thin alkali liquid is heated by virtue of an alkali liquid heating chamber; the alkali liquid heating chamber is used for warming and heating the thin alkali liquid through circulating heat-conducting oil; the temperature of the heat-conducting oil in the heat-conducting oil heating chamber rises; the heat-conducting oil returns back to the heat-conducting oil heating chamber after a thermal cycle; a hot alkali liquid is separated in a separation chamber; water is discharged through a vacuum condenser; a thick alkali liquid is discharged from the bottom of the separation chamber; the overall process is high in heat transmission efficiency; the working frequency of the overall alkali liquid concentration is improved; the heating evaporation system is environment-friendly and free of pollution; a heat-conducting oil storage tank is used for controlling a heat-conducting oil high-level pump to supplement oil to an oil storage chamber by automatically detecting the liquid level height in the oil storage chamber; normal work of the heat-conducting oil heating chamber is ensured; the unattended operation is achieved; and the efficiency is improved.

Description

technical field [0001] The invention relates to a lye concentration system, in particular to a heating evaporation system for high-level automatic oil replenishment lye concentration. Background technique [0002] Alkali concentration is to concentrate the light lye of the primary raw material into the concentrated lye used in the production of alkali flakes or alkali granules. The existing lye concentration uses an alkali pot to cook the light lye, and its heat conduction efficiency is low, making it impossible to improve the whole process. The working efficiency of lye concentration is high, and the fuel used for heating the alkali pot also pollutes the atmosphere. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a high-level automatic oil-replenishing lye concentration heating and evaporation system that improves the working efficiency of the entire lye concentrati...
