Exhaust funnel and exhaust method for wet dedusting purification

Abstract

The invention discloses an exhaust funnel and an exhaust method for wet dedusting purification. The exhaust funnel comprises a barrel, a core tube, a spiral partition plate, a heating mechanism and awater collecting funnel, the core tube is mounted in the barrel, the heating mechanism is mounted at the top end of the core tube, and is used for heating dehydrated smoke, the water collecting funnelis mounted at the bottom of the barrel of the exhaust funnel, a gap is formed between the core tube and the barrel of the exhaust funnel, the spiral partition plate is mounted between the barrel andthe core tube to form a continuous spiral channel, and the spiral channel is used for heating the dehydrated smoke and then discharging the heated dehydrated smoke.

Description

technical field [0001] The invention relates to the field of environmental protection machinery, in particular to an exhaust cylinder for wet dust removal and purification. Background technique [0002] In the wet desulfurization system and other wet dust removal and purification systems, a large amount of water needs to be sprayed into the system for cooling and dust removal and purification. During this process, the flue gas often contains a large amount of water droplets, which will produce A large number of white smoke plumes also cause a lot of waste of water resources. At present, with the continuous improvement of national environmental protection standards, the control of smoke plume at the exhaust pipe has gradually become an assessment item for the environmental protection department's environmental protection requirements for polluting enterprises. [0003] At present, independent functional sections are generally set up for the dehydration, whitening, and discha...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the existing technical problems that the dehydration, whitening and discharge of wet flue gas are independently set up with functional sections, the whole process system has a large investment at one time, the equipment occupies a large area, and the system resistance is large. The present invention aims to provide a method for The exhaust pipe and method of wet dust removal and purification can realize the efficient removal of mechanical water carried by wet flue gas in various wet dust removal and purification systems, reduce the moisture content in the flue gas, and at the same time heat the flue gas Heating, keeping the flue gas away from the saturated state, and achieving the purpose of whitening emission reduction, and the device has small resistance, and the equipment occupies a small area, and can realize dehydration and whitening emission at the same time
