Ultrasonic atomization flue gas quenching equipment

Abstract

The invention relates to ultrasonic atomization flue gas quenching equipment, which comprises an ultrasonic atomization system, a pipeline system and a wet quenching tower, and the ultrasonic atomization system is connected with the wet quenching tower through the pipeline system; the ultrasonic atomization system comprises a water storage tank and a water vapor atomization tank, the water storage tank is connected with the water vapor atomization tank through a water vapor drainage pipe, and an ultrasonic vibration plate is arranged at the bottom of the water storage tank; the pipeline system comprises a main pipe and branch pipes, and the water vapor atomization box is connected with a group of branch pipes arranged in the wet quenching tower through the main pipe; the wet quenching tower comprises a tower body, a flue gas inlet is formed in the upper end of the tower body, and a flue gas outlet is formed in the lower portion of the tower body. The equipment has the advantages of few accessory components, simpler structure, more convenience in operation, small occupied area, no blockage or corrosion problem, smaller and more uniform atomization particle size and better and more stable quenching effect, and can meet the installation and use requirements of flue gas quenching equipment in a limited space.

Description

technical field [0001] The invention belongs to the technical field of flue gas purification, and in particular relates to an ultrasonic atomization flue gas quenching device, which is especially suitable for confined spaces. Background technique [0002] Garbage generated in confined spaces such as marine ships, emergencies, and remote islands is currently mainly used for heat treatment methods such as incineration and smelting for reduction and harmless disposal. The high-temperature flue gas generated during the heat treatment needs to be cooled to 200°C within 1S by a quench cooling device, thereby inhibiting the production of harmful substances such as dioxins. However, due to limited space and special project site conditions, it is urgent to develop flue gas quenching equipment with a smaller footprint, simpler operation and maintenance, and stable effects. [0003] At present, the quench tower mainly adopts the method of gas-liquid heat exchange. The atomized water i...
