High-speed centrifugal atomization device for flue gas treatment

Abstract

The invention provides a high-speed centrifugal atomization device for flue gas treatment. The device comprises a variable-frequency motor, a speed increaser, a distributing device, an atomizing disk and a feed pipe, wherein the speed increaser, the distributing device and the atomizing disk are driven by the variable-frequency motor; the feed pipe is used for conveying liquid materials required for flue gas treatment reaction; the distributing device is sleeved on an output shaft of the speed increaser and is in clearance fit with the speed increaser; the atomizing disk is fixedly sleeved at the end of the output shaft of the speed increaser; and a discharge port of the feed pipe corresponds to the distributing device. The variable-frequency motor is used for providing working power for an atomizer, and the speed increaser increases the rotating speed of the variable-frequency motor from 2,042-2,950r / min to 9,000-13,000r / min to drive the atomizing disk to rotate at a high speed. The device mainly uses the centrifugation principle, the high-speed rotating atomizing disk efficiently and controllably atomizes alkali (or acid) liquid materials required for the flue gas treatment reaction, the atomization effect is good, and the grain size of the atomized liquid materials is less than or equal to 50mu m, so that the flue gas treatment reaction is more thorough, and the residual pollutant content is lower.

Description

technical field [0001] The invention relates to a high-speed centrifugal atomization device for efficient and controllable atomization of liquid materials (including solutions and emulsions), in particular to a device for the treatment of flue gas for atomization of alkaline (or acidic) liquid reaction materials. High-speed centrifugal atomization device. Background technique [0002] At present, the industrial field usually adopts "dry method", "semi-dry method" and "wet method" to treat the flue gas discharged into the atmosphere. , Chemical reaction and absorption of harmful ingredients. The quality of the reaction and absorption depends largely on the efficient and controllable atomization of the alkaline (or acidic) liquid materials required for the flue gas treatment chemical reaction by the atomization device installed on the spray absorption tower. The smaller the particle size of the reaction material atomized by the atomization device, the more thorough the react...

AI Technical Summary

Problems solved by technology

The above two atomization methods mainly have the following disadvantages: 1. The particle size after atomization is relatively large, resulting in insufficient purification reaction of the flue gas treatment system, and there are relatively many toxic and harmful substances in the flue gas after treatment; 2. The output of a single nozzle Small size requires a large number of nozzles; 3. The nozzle aperture is small, and it is easy to block when used for high-concentration lime emulsion; 4. The nozzle wears quickly and needs to be replaced frequently; 5. The amount of liquid material atomized and the particle size after atomization The diameter cannot be effectively controlled, so the ability to adapt to the change of working conditions of the flue gas treatment system is poor
