Glass fiber reinforced plastic desulfurizing tower for removing slag by using waste heat power

Abstract

The invention relates to the technical field of desulfurization equipment, in particular to a glass fiber reinforced plastic desulfurization tower for removing slag by using waste heat power, which comprises a tower body, uniformly distributed supporting columns are fixedly connected to the lower surface of the tower body; a slurry discharge pipe is fixedly connected to the outer circular surface of the tower body close to the edge of the lower end in a penetrating manner; an oxygenation pipe and a circulating pump pipe are fixedly connected to the lower end of the side wall of the outer circular surface of the tower body in a penetrating manner; a raw smoke guide pipe is fixedly connected to the middle lower position of the outer circular surface of the left side of the tower body in a penetrating manner; the upper end of the side wall of the inner cavity of the tower body is fixedly connected with a demisting unit; a spraying device is fixedly connected to the position, close to the lower part of the demisting unit, of the side wall of the inner cavity of the tower body; and a scraping mechanism is arranged in the middle of the side wall of the inner cavity of the tower body. Gypsum crystals in gypsum slurry in the tower body can be scraped at the beginning of formation, and the gypsum crystals are prevented from growing on the inner surface of the tower body to cause scaling on the inner wall of the tower body and gradually form a gypsum scale layer.

Description

technical field [0001] The invention relates to the technical field of desulfurization equipment, in particular to a glass fiber reinforced plastic desulfurization tower utilizing waste heat power to remove slag. Background technique [0002] The desulfurization tower is the equipment for desulfurization treatment of industrial waste gas. The desulfurization tower was originally the most widely used granite masonry. . The advantage is that it is easy to maintain, and the effect of dust removal and desulfurization (denitrogenation) can be achieved at the same time by formulating different dust collectors. Now with the development of FRP technology, the desulfurization tower is gradually changed to FRP manufacturing. Compared with granite desulfurization towers, FRP desulfurization towers have low cost, easy processing, rust resistance, and light weight, so it will become the development trend of desulfurization towers in the future. [0003] When the existing FRP desulfuri...

Problems solved by technology

[0004] In the prior art, the exhaust gas with high temperature has a high flow rate after being pressurized by the booster fan, and the direct discharge after desulfurization by the absorption tower will cause a lot of waste of heat, and in the absorption tower, the inner wall of the absorption tower will form a gypsum scale layer , Increase the maintenance workload of maintenance workers, the hard scaling layer will damage the damage of the anti-corrosion layer of the equipment, accelerate the corrosion of the equipment, cause leakage of the equipment tower body, and the small scaling body will be transported to the slurry spray layer through the circulating slurry pump , to accelerate the wear of the impeller of the slurry circulation pump, causing nozzle blockage, shedding, and spray layer blockage
