Description

Technical Field

[0001] The utility model relates to the field of novel cloth bags, in particular to a novel cloth bag for reducing the concentration of dioxins in lead smelting fume. Background Art

[0002] The concentration of dioxins in the flue gas of lead smelting strictly controls the smelting of high-chlorine-containing materials, uses dioxin inhibitors and strengthens flue gas treatment, such as the built-in nano-energy wave material in the gas activation and tempering energy-saving device. The material itself can generate a high-intensity energy field, which breaks up the large molecular clusters that are gathered and clumped into small molecules, increases the distance between methane molecules, increases the activity of natural gas, and then increases the oxygen-receiving area of ​​methane, making it easier to combine with oxygen molecules, making the combustion more complete, improving the combustion efficiency, reducing fuel consumption, and ultimately reducing the CO content and NOx content in flue gas emissions. According to different combustion conditions, 5%-10% of gas can be saved. In the lead smelting process, incomplete combustion of fuel and raw materials or improper control of combustion temperature can easily produce chlorine-containing organic matter such as chlorobenzene, which are precursors for dioxin synthesis;

[0003] After lead is put into the furnace for smelting, it needs to be filtered with bags before being discharged into the atmosphere. Since low-lead smelting flue gas contains a large amount of dioxin toxic gases, the emission concentration of dioxins should be reduced during the bag filtration process. Therefore, in response to the above problem, the applicant has proposed a new type of bag for reducing the dioxin concentration in lead smelting flue gas. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a new type of cloth bag for reducing the concentration of dioxins in the fume of lead smelting.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The utility model has the following beneficial effects:

[0007] In the utility model, the activated carbon adsorption cloth is arranged so that the activated carbon adsorbent can specifically adsorb dioxin molecules, improve removal efficiency and adsorption, and through high-efficiency filtration and adsorption, the ultraviolet irradiation of the ultraviolet sterilization lamp can stimulate the activity of the catalyst coating and promote its catalytic decomposition of dioxins, thereby reducing the concentration of dioxins in lead smelting; the second Velcro is bonded to the first Velcro, and the activated carbon adsorption cloth is designed to be replaceable so that it can be replaced after adsorption saturation, thereby extending the service life of the bag and reducing the operating cost.
