Abstract

The invention discloses a flash evaporator for gasifying liquid phase substances. The flash evaporator comprises an outer flash tank frame body and an outer demister frame body, wherein a flash tank gas phase outlet, a flash tank material inlet and a manhole are formed in the outer surface of the outer flash tank frame body; a downcomer is mounted in the outer flash tank frame body; a primary distributor is mounted under the downcomer; a distributor is mounted under the primary distributor; V-shaped weirs, a flash tank bed casting die, a flash tank bed and a flash tank bed supporting layer are mounted under the distributor; a concentrated solution gathering tank is mounted under the flash tank bed supporting layer, and a concentrated solution outlet of a flash tank is formed in a position under the flash tank bed supporting layer; a demister bed is mounted in the outer demister frame body; and a demister outlet and a demister inlet are formed in the outer surface of the outer demister frame body. The flash evaporator disclosed by the invention has the advantages that the flash efficiency of liquid phase materials is high; the flashed materials cannot have the phenomenon that materials and foams are mixed; and materials which are easy to crystallize cannot block the distributor and fillings.

Description

technical field [0001] The invention relates to a flash evaporator used for vaporizing liquid-phase substances, which belongs to the field of mechanical equipment in the chemical industry. Background technique [0002] In the prior art, the flash evaporation process is often used in the chemical industry, etc., and is mainly used for concentrating liquid-phase substances or extracting useful substances in liquid-phase substances. The flash evaporation tank basically adopts a large airtight pressure-resistant storage tank, and the material directly enters the flash evaporation tank. The flash tank is used for flash evaporation, and the flash evaporation efficiency is low; some manufacturers adopt the rotary cutting method along the inner wall of the flash tank to enter the flash tank, and the efficiency has been improved, but the overall efficiency is still low. How to improve the flash evaporation efficiency of the flash tank and reduce energy consumption is a problem that n...
