Abstract

The invention discloses a material distributing and defoaming device of an evaporator. The device comprises a feeding pipe arranged on the wall of the evaporator in a penetrating manner, wherein a bend of the feeding pipe is arranged in the evaporator and is communicated with a vertical medium dispersion device; the medium dispersion device comprises a tubular side wall and an umbrella-shaped top cover which are fixedly connected; strip-shaped spraying holes are circumferentially arranged in the tubular side wall in parallel; the horizontal intervals between the adjacent spraying holes in each row of spraying holes are same; the two adjacent rows of spraying holes are staggered from each other; the diameter of the umbrella-shaped top cover is 2-3 times that of the top of the tubular side wall. The device is relatively high in processing capacity and defoaming efficiency.

Description

technical field [0001] The invention relates to an evaporation separation device, in particular to an evaporator material distribution and defoaming device. Background technique [0002] The secondary steam generated by evaporation is usually mixed with solution droplets, especially in the forced circulation evaporator, due to the pressure of the delivery pump, the flow rate of the material entering the separator is fast, and it is easy to impact the equipment, causing the solution to splash and generate foam. , these foams will enter the next effect heat exchanger under the action of negative pressure, and will be discharged after heat exchange and condensation, resulting in the loss of products, especially for the evaporation and crystallization equipment used for sewage treatment, the existence of foams will cause the loss of condensed water COD exceeds the standard and the loss of products. [0003] In order to solve the above problems, the inventor has previously p...
