High-pressure self-rotation centrifugal air washer

Abstract

The invention provides a high-pressure self-rotation centrifugal air washer. The high-pressure self-rotation centrifugal air washer comprises N high-pressure spray heads and N self-rotation impellers corresponding to the N high-pressure spray heads, wherein the self-rotation impellers are located right above the high-pressure spray heads; nozzles of the high-pressure spray heads are narrow-angle solid cone nozzles and are used for vertically jetting slurry upwards; the self-rotation impellers comprise impeller shafts, impeller brackets and blades, and the centers of the impellers rightly face to the high-pressure spray heads; a plurality of flow guide pipes are arranged at the lower ends of the self-rotation impellers; and the high-pressure spray heads and the bottom surfaces of the flow guide pipes are located on the same horizontal plane. The high-pressure self-rotation centrifugal air washer has the beneficial effects that by virtue of actions of high pressure, shearing, rotational flow, centrifugation and the like, the fogging degree of absorption liquid is greatly increased, the gas-liquid mass transfer coefficient is increased, the energy consumption is saved, and the operation cost is lowered.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, in particular to a high-pressure spin centrifugal scrubber. Background technique [0002] According to different requirements for pollutant purification, industrial flue gas treatment processes are mainly divided into desulfurization process, desulfurization and denitrification process, and multi-pollutant collaborative purification process. According to the state of the product and reaction conditions, it can be divided into three categories: dry method, wet method and semi-dry method. Among them, the wet process is the most widely used. After a certain pretreatment, the flue gas is finally absorbed by alkaline slurry in the absorption tower to remove pollutants. At present, the spray method is the most widely used absorption and purification method in the absorption tower, and it is favored for its stable and reliable operation and high absorption and purification efficiency. ...

AI Technical Summary

Problems solved by technology

[0003] The main absorption and purification methods currently used in the market all have the phenomenon of "three highs and two lows" of high investment, high operating costs, high maintenance rate, low purification efficiency, and low gas-liquid mass transfer coefficient.

The booster fan is one of the main energy-consuming equipment in the flue gas purification process. The investment and maintenance costs are relatively high. The spray device increases the height of the absorption tower, which greatly increases the project cost. These aspects have increased the investment and cost of environmental protection facilities. Operating costs

In addition, as environmental protection requirements become increasingly stringent and environmental protection standards gradually increase, the traditional single-stage absorption purification method has low gas-liquid mass transfer coefficient and poor purification efficiency, which is far from the current environmental protection requirements.
