Ultrasonic atomization deacidification dedusting system

Abstract

The invention provides an ultrasonic atomization deacidification dedusting system, which comprises an alkali lye preparation device. The alkali lye preparation device comprises a preparation barrel for containing alkali lye, a liquid return pipeline with one end communicated with the bottom of the preparation barrel and the other end communicated with the middle part of the preparation barrel, and a liquid return pump which is arranged on the liquid return pipeline. A liquid inlet of the liquid return pump is communicated with the bottom of the preparation barrel through the liquid return pipeline, and a liquid outlet of the liquid return pump is communicated with the middle part of the preparation barrel through the liquid return pipeline. Thus, alkali lye in the preparation barrel is circulated. The invention has the following beneficial effects: the liquid return pipeline and the liquid return pump are used to replace a mechanical agitator, and service time of the liquid return pipeline and the liquid return pump is long such that service life of the ultrasonic atomization deacidification dedusting system is prolonged.

Description

technical field [0001] The invention relates to domestic waste incineration equipment, in particular to an ultrasonic atomization deacidification and dust removal system. Background technique [0002] In the prior art, in order to incinerate domestic waste, domestic waste incineration equipment is used. The domestic waste incineration equipment includes: a pyrolysis gasifier for incinerating domestic waste; a waste heat boiler connected to the pyrolysis gasifier; The flue gas produced by the gasifier is input into the waste heat boiler to process the temperature of the flue gas; the ultrasonic atomization deacidification and dust removal system connected with the waste heat boiler is used to deacidify the flue gas; and the ultrasonic atomization deacidification and dust removal system is connected A connected bag filter to remove dust from the flue gas. [0003] Generally, the ultrasonic atomization deacidification and dedusting system includes: the lye configuration device...

AI Technical Summary

Problems solved by technology

[0003] Generally, the ultrasonic atomization deacidification and dedusting system includes: the lye configuration device uses an ultrasonic atomization deacidification and dust removal tower, and a mechanical stirrer is installed in the lye configuration device to mix lime powder and water evenly; The dedusting tower includes a tower body. The upper part of the tower inner chamber is a smoke inlet chamber, and the lower part is a deacidification reaction chamber. The bottom of the deacidification reaction chamber is a lye pool. Although the lye configuration device in the device has obtained evenly mixed lye, and the ultrasonic atomization deacidification and dedusting tower has also realized the deacidification of smoke, the disadvantages that still exist in this device are: 1) the lye configuration device uses The mechanical stirrer needs to penetrate into the lye for a long time, so its service life is extremely short; 2) In order to make the alkali mist in the deacidification reaction chamber thicker, it should prevent the alkali mist from entering the smoke chamber from the smoke inlet pipe, but generally The smoke inlet pipe is only a through pipe. If the air pressure in the deacidification reaction chamber is greater than the air pressure in the smoke inlet chamber, the alkali mist will enter the smoke inlet chamber from the smoke inlet pipe.
