TECHNICAL FIELD

[0001] The application relates to the technical field of desulfurizer preparation, in particular to a preparation device and method of zinc oxide desulfurizer. BACKGROUND

[0002] With the continuous rise of the proportion of fossil fuels in the global energy structure, the sulfur-containing harmful substances generated in the combustion process have become an important inducement for environmental problems such as acid rain. Therefore, countries around the world have introduced strict regulations to limit the sulfur content in oil and gas, and have promoted the continuous upgrading of low-sulfur, ultra-low-sulfur clean oil production technology. In the oil processing link, active sulfur can be converted into hydrogen sulfide under conventional conditions; although non-active sulfur such as thiophene is stable in chemical properties, it can also decompose to produce hydrogen sulfide gas in the process of catalysis, heating and the like, and the zinc oxide desulfurizer is widely used in the field of oil processing due to its high desulfurization precision.

[0003] At present, the preparation methods of the zinc oxide desulfurizer mainly include a solid phase method, a liquid phase precipitation method, a sol-gel method, a hydrothermal synthesis method and an impregnation method, wherein the operation process of the liquid phase precipitation method is that a soluble zinc salt is dissolved in deionized water, a precipitant is added, the generated precipitate is aged and placed, and then is baked and formed. However, in actual operation, the precipitant is usually directly injected into a reaction tank, and then is mixed by a stirring device in the tank. Since the precipitant is in a downward diffusion state after being injected, the mixing speed of the materials in the stirring process is slow, and the reaction efficiency is affected. In addition, the water outlet of the reaction tank is usually controlled by a valve, and when the generated precipitate is discharged, if the precipitate is aggregated to form a large-particle-size flocculation or sediment, the valve is easily blocked, and it is inconvenient to clean.
