Annular spray evaporation device

Abstract

The invention provides an annular spray evaporation device. The annular spray evaporation device at least comprises an evaporation chamber which comprises a shell, an annular spray atomizer, an in-built plug-in filler drum, U-shaped heating rings and a vapor-liquid distribution disc, wherein the upper part of the shell is provided with a volatile phase outlet, and the lower part of the shell is provided with a non-volatile phase outlet; the annular spray atomizer, the U-shaped heating rings and the vapor-liquid distribution disc are arranged inside the shell; the annular spray atomizer is connected with a feed liquid booster pump by passing through a feed liquid inlet pipe, a preheater and a filter; the U-shaped heating rings are connected with a heat medium; and the top end of the in-built plug-in filler drum arranged inside the shell is provided with the vapor-liquid distribution disc which is composed of a reflux liquid conduit, a reflux distributor and a ventilation pipe. The evaporation device provided by the invention can fully and efficiently utilize heat energy, realizes continuous operation, simplifies equipment, saves space and reduces investment.

Description

technical field [0001] The invention relates to the technical field of evaporation, concentration, distillation and rectification equipment, in particular to an annular spray evaporation device. Background technique [0002] The so-called evaporation is to heat the mixed liquid to be separated to boiling, use the pipeline to draw out the generated steam, and then condense it. As a result, the condensed liquid and the liquid with a different concentration from the original mixed liquid are obtained, and finally the liquid and the substances dissolved in the liquid are obtained. purpose of separation. [0003] Evaporation is the basic process of distillation and rectification. [0004] The main equipment for traditional evaporation includes: concentrated evaporator (rising film, falling film, transferred film evaporator), evaporation tower, reboiler, condenser, reflux conveying equipment, etc. The equipment that mainly generates boiling is the reboiler, and the main evaporat...

AI Technical Summary

Problems solved by technology

Although this technology saves steam, it needs a steam compressor

The increase in equipment investment is a small problem, and the secondary steam is often a flammable gas, which is easy to cause accidents due to mechanical friction and sparks during the vibration or swing of the compressor rotor, that is, the safety is poor

[0009] The evaporation (rectification) process realized by the evaporation equipment in the prior art not only consumes a lot of energy when evaporating and treating the reflux, but also the raffinate discharged often does not meet the national environmental protection requirements
