Integrated device for removal of dusts and gaseous pollutants

Abstract

The invention relates to an integrated device for the removal of dusts and gaseous pollutants, which comprises a bracket and a bag-type dust remover, wherein the bag-type dust remover consists, from top to bottom, of an ash cleaning device, a box body, an ash compartment and an ash unloading device, the box body is internally provided with a plurality of filter bags installed vertically, the filter bags are internally or externally provided with adsorbers corresponding to the filter bags one by one, and the adsorbers are installed inside the box body via an adsorber support cage. The adsorber is internally filled with carbon-based adsorbent through which the gaseous pollutants are adsorbed. According to the invention, the integrated device is formed by integrating dust removal with the gaseous pollutant removal, the carbon-based adsorbent having large surface area can be regenerated many times and repeatedly used to lower the operating expenditure, and the integrated device of the invention can effectively remove particles, SO2, Nox, Hg and toxic and harmful organic pollutants resulting from industrial discharge in the same device, and has the advantages of simple structure, small floor area and excellent dust removal and adsorption effects.

Description

technical field [0001] The invention belongs to the fields of industrial waste gas purification, environmental protection and chemical industry, and in particular relates to an integrated dust removal and gaseous pollutant removal device. Background technique [0002] my country is a country with scarce water resources, and the distribution of water resources is uneven. The task of saving water in the development of energy industry is very severe. Commonly used flue gas desulfurization technology uses water as solvent and calcium base as absorbent. Calcium-based absorbents are derived from non-renewable resources such as limestone or dolomite, which have been used as strategic reserves in developed countries. Due to the extensive application of limestone and dolomite in industries such as steel, cement, and building materials, the high-quality parts will be exhausted in the next few decades. Most of the integrated dust removal and gaseous pollutant removal devices used in ...

AI Technical Summary

Problems solved by technology

The system divides the removal of gaseous pollutants and dust removal into separate parts. The system is relatively complex; it has a large footprint; each part affects each other; dust removal is placed after the removal of pollutants, and the dust is easy to block the pores of the carbon-based adsorbent. For example, "a flue gas treatment process" disclosed in the Chinese patent application number 200910050491.X and the "semi-dry waste incineration flue gas purification treatment method and system" disclosed in the Chinese patent application number 200810069384.7

In the bag filter, there is a bag filter made of activated carbon non-woven fabric, which has the ability to remove dust and gaseous pollutants at the same time, but the disadvantage is that the adsorbent is combined with the filter bag, and the activated carbon is difficult to regenerate. Bring bigger waste and higher investment, as the disclosed "activated carbon non-woven fabric" of the Chinese patent No. "
