AI Technical Summary

Technical Problem

In existing industrial waste gas desulfurization and purification devices, the waste gas passes through the purification tower for a short time, resulting in insufficient contact time between the purification liquid and the sulfide, which affects the desulfurization effect.

Method used

A swirl mechanism and a transmission mechanism are used to form an efficient rotating flow field, which prolongs the residence time of the exhaust gas in the tower. The exhaust gas is given a tangential velocity through spiral blade guidance and inclined blades, so that a spiral upward flow field is formed in the desulfurization tower, which increases the contact opportunity with the reaction liquid, and the reaction liquid is sprayed through the atomizing nozzle for sufficient reaction.

Benefits of technology

It achieves full contact between the exhaust gas and the purification liquid, improves the desulfurization purification efficiency, prolongs the residence time of the exhaust gas in the tower, enhances the absorption effect of sulfides, and improves the maintenance convenience of the device through the automatic cleaning function.

Abstract

The invention relates to the technical field of waste gas treatment, and discloses a desulfurization purification device and process based on industrial waste gas treatment.The desulfurization purification device comprises a desulfurization tower, a rotational flow mechanism, a transmission mechanism and a solid-liquid separation mechanism and further comprises a collection box fixedly installed at the bottom of the desulfurization tower and a dust removal mechanism fixedly installed on one side of the desulfurization tower; according to the technical scheme, through the combined action of spiral blades in the rotational flow mechanism and the transmission mechanism, an efficient rotating flow field is formed, the retention time of waste gas in the tower is prolonged, sulfide and atomized reaction liquid are more fully contacted, chemical reaction of the reaction liquid on the sulfide is promoted, and therefore efficient sulfide removal and purification are achieved; wherein the rotational flow mechanism endows the waste gas with tangential speed through inclined blades in the rotational flow mechanism, so that the waste gas rotates, a spiral ascending flow field is formed in the desulfurization tower, the retention time of the waste gas is prolonged, the contact opportunity of the waste gas and atomized reaction liquid is increased, sulfide absorption is facilitated, and the desulfurization purification effect is improved.
