Dynamic wave system used for treating combustion flue gas of electronic waste material

Abstract

The invention discloses a dynamic wave system used for treating combustion flue gas of an electronic waste material. The dynamic wave system comprises: a reaction tower, wherein a gas-liquid separation section is arranged in the reaction tower, and a purified flue gas outlet communicated with the gas-liquid separation section is arranged on the reaction tower; a reverse spraying pipe, wherein at least a part of the reverse spraying pipe is arranged in the reaction tower, and the reverse spraying pipe is provided with a flue gas inlet and an absorption slurry outlet communicated with the gas-liquid separation section; and a liquid inlet nozzle used for upwardly spraying an absorption liquid, wherein the liquid inlet nozzle is arranged in the reaction tower, has an upward opening and is located below the flue gas inlet. According to embodiments in the invention, the dynamic wave system used for treating combustion flue gas of the electronic waste material has the advantages of a substantial purifying effect, a good gas-liquid separation effect, etc.

Description

technical field [0001] The invention relates to a dynamic wave system for treating flue gas of electronic waste combustion. Background technique [0002] At present, the flue gas treatment devices mainly include packed towers and empty towers, etc., which are widely used in the field of flue gas purification in coal, chemical, metallurgical and other industries, including single treatment—desulfurization or dust removal, and two comprehensive treatment equipment, The purification effect and efficiency of the comprehensive treatment equipment have been improved. [0003] The purpose of using a packed tower is to increase the contact time of gas and liquid to achieve a higher desulfurization rate, but it will inevitably cause plugging of the packing, which not only reduces the contact area of ​​the reaction, but also increases the resistance of the flue gas. The maintenance after the blockage is quite difficulty. Empty towers are often equipped with circulating fluid spray l...

AI Technical Summary

Problems solved by technology

[0003] The purpose of using a packed tower is to increase the contact time of gas and liquid to achieve a higher desulfurization rate, but it will inevitably cause plugging of the packing, which not only reduces the contact area of ​​the reaction, but also increases the resistance of the flue gas. The maintenance after the blockage is quite difficulty

Empty towers are often equipped with circulating fluid spray layers and multi-stage demister layers, but it is difficult to solve the problem of low desulfurization and dust removal efficiency due to poor mass transfer response capabilities, and multi-stage devices increase the resistance of flue gas discharge

In short, the traditional packing tower and empty tower purification flue gas treatment often have poor purification effect
