Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas desulfurization, in particular to an industrial waste gas desulfurization device. Background Art

[0002] Industrial waste gas refers to the general term for various pollutant gases discharged into the air during fuel combustion and production processes within the factory area of ​​an enterprise. Waste gas discharged into the atmosphere will pollute the air. These waste gases enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have an accumulation effect, which will more seriously endanger human health. In the process of industrial waste gas treatment, the sulfur oxides contained in the waste gas need to be treated to prevent the sulfur oxides from entering the atmosphere and forming acid rain.

[0003] A Chinese patent application with publication number CN215352497U discloses an industrial waste gas desulfurization treatment device, including a desulfurization tower body, an output shaft of a motor passing through the desulfurization tower body and fixedly connected with a connecting block, a scraper is placed at the bottom of the inner cavity of the desulfurization tower body, one end of the scraper is provided with a connecting groove matching the connecting block, and two fixing bolts are fixedly installed between the scraper and the connecting block, the front surface of the exhaust hood is symmetrically provided with card slots, and a dustproof net is placed inside the exhaust hood, and the front surface of the exhaust hood is symmetrically rotatably connected with baffle rods, each baffle rod is fixedly connected to the exhaust hood with a torsion spring, and the outer side of the baffle rod is in contact with the front surface of the card block, and by placing the dustproof net inside the exhaust hood, dust can be prevented from entering the interior of the desulfurization tower from the exhaust pipe and causing pollution, and at the same time, by pulling the baffle rod, the torsion spring is elastically deformed, so that one end of the baffle rod is separated from the restriction on the position of the card block, thereby facilitating the removal of the dustproof net for cleaning.

[0004] However, the above-mentioned industrial waste gas desulfurization treatment device in the prior art has the following disadvantages in actual use:

[0005] 1. In the industrial waste gas desulfurization site, there is a lot of dust in the air, and dust is more likely to accumulate on the dust-proof net. In order not to affect the exhaust, personnel need to clean it frequently, which greatly increases the labor burden of personnel.

[0006] 2. The gas in the desulfurization tower is generally discharged directly from the exhaust pipe, but with the setting of the dustproof net, the exhaust efficiency will be affected to a certain extent.

[0007] To this end, we provide an industrial waste gas desulfurization device to solve the above problems. Utility Model Content
