Vane-type demister

Abstract

The invention discloses a vane-type demister, which comprises a shell and vanes, wherein an airflow inlet is arranged at the front side of the shell; an airflow outlet is arranged at the back side; a bleeder tube is arranged on the shell; a plurality of vanes are arranged inside the shell; a flow channel is formed between the adjacent vanes; the inlet end of the flow channel corresponds to the airflow inlet of the shell; the outlet end of the flow channel corresponds to the airflow outlet of the shell; and the vanes are of a streamline structure and form an S shape of a mirror image. The vanes disclosed by the invention can be optimized and designed according to airmechanics and completely meet the airflow flowing characteristics, and when airflow flows in the flow channel, fine droplets contained in the airflow are captured by inertia difference between the airflow and the fine droplets.. The vane-type demister has the characteristics that the structure is simple, the maintenance is convenient, the capture efficiency is high and the pressure loss of the airflow is small.

Description

technical field [0001] The invention relates to a mist eliminator, in particular to a vane type mist eliminator, which is especially suitable for seawater desalination, rectification treatment, condensed air separation, impurity separation and the like. Background technique [0002] Seawater desalination is an open-source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water without being affected by time, space and climate. The water quality is good and the price is gradually becoming more reasonable. It can ensure a stable water supply such as drinking water for coastal residents and replenishment water for industrial boilers. Low-temperature multi-effect seawater desalination technology has developed rapidly in recent years due to its characteristics of low operating temperature, high heat transfer efficiency, reasonable cost, and energy saving.

AI Technical Summary

Problems solved by technology

However, due to the large energy consumption required for the operation of the mist-water separation device, the cost of seawater desalination will directly increase, and when the fine droplets in the seawater vapor are separated, the flow of seawater vapor will be greatly hindered ( It will even change the flow direction of part of the seawater vapor), so that the seawater vapor has a large pressure drop, which cannot meet the requirement that the temperature difference between the effect and the effect of the horizontal horizontal tube falling film evaporator should be kept at 2 ~ 3 ℃, which leads to the horizontal horizontal tube falling film evaporator. The tube falling film evaporator does not desalinate the seawater thoroughly, and the desalination efficiency is low, which further increases the cost of seawater desalination

In addition, the mist-water separation device also has the disadvantages of complex structure, large volume, and high cost.
