Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization equipment, in particular to a more uniform desulfurization catalyst production adding structure. Background Art

[0002] In the process of industrial production, a large amount of sulfide is generated. For example, chemical fuels such as coal or petroleum and the chemical raw materials produced therefrom, as well as wastewater and exhaust gas discharged from industrial production all contain sulfide. Sulfide mainly comes from sulfur substances contained in the raw materials. Sulfur substances react and transform into sulfide during the industrial production process, and are then released. Sulfide, especially hydrogen sulfide and sulfur dioxide, often causes poisoning and deactivation of catalysts in the production process. Moreover, direct discharge of wastewater and exhaust gas containing sulfide is also likely to pollute the environment, causing poisoning of humans and animals, which is extremely harmful.

[0003] Desulfurization catalyst is a medicine used to accelerate the efficiency of removing sulfide from raw materials, wastewater, waste gas or other materials to reduce the sulfide content, which is beneficial to industrial production and environmental protection. At present, there are two common methods for using desulfurization catalyst. One is to add the catalyst directly to the reaction tank in multiple times to activate it and make it work. The other is to use a simple dosing box, add the required catalyst to the dosing box at one time, add a certain amount of water, and then stir it to dissolve and activate it, and then slowly add the activated solution to the reaction tank.

[0004] Both of the above methods have obvious shortcomings. The first method of adding the catalyst is that the direct addition of the catalyst without activation will cause the catalytic effect to deteriorate, and the intermittent addition of the catalyst will cause large fluctuations in the effective components of the catalyst in the desulfurization liquid, causing fluctuations in the desulfurization efficiency of the entire system, resulting in reduced desulfurization efficiency. The second method is improved over the first method and can activate the catalyst to a certain extent, but it increases the time for adding the catalyst, and still cannot ensure the uniform addition of the catalyst, affecting the efficiency of desulfurization.
