Problems solved by technology

The arc-shaped material box is used to guide the material to spirally decelerate and drop, cut into the material in the shell and then mix with it, avoiding the foam generated by splashing, but limited by the outlet size of the material box, a small amount of liquid foam will still be produced when the flow rate is fast. It has become a bottleneck in improving the processing capacity of evaporation and crystallization equipment, and there is an urgent need for a defoaming device that can effectively suppress liquid splashing at high flow rates

Abstract

The invention discloses an evaporator separator material distributing foam-removing device. The evaporator separator material distributing foam-removing device comprises a feeding pipe which penetrates through an evaporator separator wall, wherein the feeding pipe is provided with an elbow in an evaporator separator; the elbow is communicated with a medium dispersing device which is vertically arranged, the medium dispersing device comprises a pipe-shaped side wall and an umbrella-type top cover which are fixedly connected, the pipe-shaped side wall is provided with round spraying holes in an arranging manner, the spraying holes are parallelly arranged along the circumference of the pipe-shaped side wall, and the quantity of the spraying holes of each row is successively reduced along a feeding direction. The evaporator separator material distributing foam-removing device provided by the invention has high processing capacity and foam-removing efficiency.

Description

technical field [0001] The invention relates to evaporation and separation equipment, in particular to a material distribution and defoaming device for an evaporator separator. 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 inven...
