Material evaporator with liquid level balancing function

Abstract

The invention discloses a material evaporator with a liquid level balancing function. The material evaporator includes a shell, and an overflow plate and two sets of horizontal pipe falling film evaporation devices are fixed in the shell; each horizontal pipe falling film evaporation device comprises a horizontal pipe evaporation mechanism, a steam distribution chamber, a steam rotary chamber anda U-shaped condensate water discharging mechanism, the steam distribution chamber and the steam rotary chamber are respectively located at a steam inlet end and a steam outlet end of the horizontal pipe evaporation mechanism, and the U-shaped condensate water discharging mechanism is located in the steam distribution chamber and used for discharging condensate water and non-condensable gas; a steam outlet is disposed at the top of the shell; a condensate water discharge port and two material circulating barrels are fixed at the bottom of the shell, material circulating feed inlets are respectively arranged on two side walls of the shell, and the two material circulating feed inlets are respectively communicated with the two material circulating barrels through pipelines with pumps. According to the invention, the material evaporator can realize stepped concentration of materials on the premise of small space occupation, and at the same time can keep sealing of steam while discharging condensate water, thus completing evaporation and concentration of materials efficiently.

Description

technical field [0001] The invention relates to the technical field of heat exchange, in particular to a material evaporator with a liquid level balance function. Background technique [0002] The horizontal tube falling film evaporation technology is to add the feed liquid from the upper tube box of the heating chamber of the falling film evaporator, and evenly distribute it to each heat exchange tube through the liquid distribution and film forming device. Membrane flow from top to bottom. During the flow process, the feed liquid exchanges heat with the horizontal tube with steam inside to achieve the purpose of evaporation and concentration. At present, the horizontal tube falling film evaporation technology is widely used in the evaporation and concentration of fluid material water in medicine, food, chemical industry, light industry and other industries due to its good evaporation and concentration effect, as well as sewage treatment in steel, catalyst manufacturing, m...

AI Technical Summary

Problems solved by technology

However, in the actual application process, due to the sequential arrangement of multi-stage heat exchange tube bundles, the overall length is longer and the space occupation is larger

The number of separation boxes is large, resulting in complex structure and high cost

Moreover, the structure in which the condensate flows out through the separation box also easily causes the steam to be discharged together with the condensate, thereby affecting the heat exchange effect
