Boiler sulfur removal and dust removal device

Abstract

The invention discloses a boiler sulfur removal and dust removal device which comprises a boiler body. The boiler body is connected with a sulfur removal tank through an irregular gas pipe arranged on one side, a filter screen layer, an electrostatic dust removal layer and an activated carbon filtration layer are respectively arranged in the irregular gas pipe, a water draining pipe is arranged at the bottom of the irregular gas pipe, a scale removing spray head is arranged on the inner wall of the top of the irregular gas pipe, a waste liquid discharging pipe is arranged at the bottom of the sulfur removal tank, a liquid inlet pipe is arranged on the side, away from the irregular gas pipe, of the sulfur removal tank, and a smoke discharging pipe is arranged at the top of the sulfur removal tank. The boiler sulfur removal and dust removal device makes dust and peculiar smell in smoke effectively filtered, the filtered dust is subjected to cleaning of the scale removing spray head and then is discharged out of the water draining pipe, dust clearing is promoted, a blockage phenomenon is effectively avoided, sulfur in the smoke can be completely cleared, the problem that a traditional sulfur removal method is not thorough in sulfur removal is effectively avoided, the sulfur removal efficiency is greatly improved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler desulfurization and dust removal device. Background technique [0002] Sulfur dioxide is a gaseous pollutant with a relatively large content and a wide range of influences in the current air pollutants. There are many sources of sulfur dioxide in the atmosphere, and almost all industrial enterprises may produce it. It mainly comes from the combustion process of chemical fuels (coal, oil and natural gas), as well as the roasting and smelting of sulfide ores, thermal power generation, non-ferrous metal smelting plants, sulfuric acid plants, oil refineries, and coal-fired industrial boilers and furnaces and so on emit sulfur dioxide fumes. In the past desulfurization process, the desulfurizer is usually sprayed into the flue gas, and the desulfurizer reacts with the sulfur dioxide in the flue gas during the continuous discharge of the flue gas to remove the sulfur dioxide...

AI Technical Summary

Problems solved by technology

However, in such a desulfurization process, there is a problem that the desulfurization agent is not completely mixed with the flue gas and the desulfurization effect is poor.

In addition, there are problems that the inlet of the dust collector is easy to be blocked, and the dust collector is not easy to maintain
