Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization towers, in particular to a high-efficiency fuel gas desulfurization tower structure. Background Art

[0002] Desulfurization tower is a tower-type equipment for desulfurization of industrial waste gas. Desulfurization tower was originally built with granite and was most widely used. It uses the principle of water film desulfurization and dust removal. It is also called granite water film desulfurization dust collector or granite water film desulfurization dust collector. It has the advantages of easy maintenance and can achieve the effect of dust removal and desulfurization at the same time by preparing different dust removal agents. With the development of FRP technology, desulfurization towers are gradually changed to be made of FRP. Compared with granite desulfurization towers, FRP desulfurization towers have low cost, easy processing, no rust and no rot, and light weight, so they have become the development trend of desulfurization towers in the future.

[0003] For example, the authorization announcement number "CN219848945U" is named a petrochemical gas desulfurization tower. Although the second motor drives the second shaft to rotate, and the second shaft drives the rotating block to rotate, so that the neutralizing liquid is evenly discharged into the cylinder through the circular hole, which is beneficial to the full reaction of industrial waste gas and the neutralizing liquid, the existing petrochemical gas desulfurization tower uses a rotating neutralizing solution to react with the sulfur substances in the gas to form sulfide salts that are easier to handle and discharge. However, the attachment pipe only occupies a small area at the bottom of the desulfurization tower, and the rotating attachment pipe can be in contact with the sulfur-containing gas for a relatively short time, and it is difficult to complete a relatively sufficient reaction in a short time. As a result, a large amount of gas is not fully converted into sulfide salts and moves upward along the inside of the desulfurization tower, which not only increases the burden of processing on the upper collecting plate, but also reduces the speed at which the desulfurization tower processes sulfides, affecting the relatively low working efficiency of the petrochemical gas desulfurization tower.

[0004] At the same time, the existing petrochemical gas desulfurization tower uses a neutralizing solution to utilize the attached tube and the sulfur-containing gas to contact and react to achieve purification and desulfurization. However, a certain amount of sulfide salt substances will be formed after the sulfide reaction. Although the sulfide salt is relatively small in harm, the sulfide salt will solidify and accumulate at the bottom of the desulfurization tower, thereby affecting the rotation of the upper attached tube. The liquid sulfide salt is discharged from the desulfurization tower without being filtered and will pollute nearby water bodies and soil, which directly leads to unsatisfactory subsequent treatment effects of the petrochemical gas desulfurization tower. Utility Model Content

[0005] The utility model aims to solve the problems of low working efficiency and inadequate subsequent treatment in the existing petrochemical gas desulfurization tower, and proposes a high-efficiency gas desulfurization tower structure.

[0013] Preferably, two inspection holes are fixedly installed at the front end of the outer wall of the desulfurization tower body, and the inner sides of the two inspection holes and the spray box are arranged opposite to the filter screen.

[0014] The utility model proposes a high-efficiency gas desulfurization tower structure, which has the beneficial effect that when the pump is started, the external neutralizing solution flows into the spray box along the liquid inlet pipe, and then is sprayed to the interior of the desulfurization tower body at multiple nozzles below the spray box, so as to neutralize and desulfurize the rising sulfur-containing gas. The multiple structures of uniform spraying and preliminary filtration are utilized to improve the working efficiency of the high-efficiency gas desulfurization tower structure.

[0015] The sulfide salts produced by the reaction after the spraying treatment will fall and encounter the reaction layer, and the solid crystalline sulfide salts with larger particles will remain above the reaction layer. The spraying liquid and the wastewater containing sulfide salts will be purified by the filter layer and discharged along the drain pipe. The sealed door can be flipped open along the hinge, and then the sulfide salts accumulated above the reaction layer can be manually removed and discharged to avoid accumulation. The structure that can effectively treat the sulfide salts after the reaction is completed improves the subsequent treatment effect of the high-efficiency gas desulfurization tower structure.
