Spraying and dipping equipment for catalyst

Abstract

The invention discloses spraying and dipping equipment for a catalyst. The spraying and dipping equipment for the catalyst comprises an upper shell and a lower shell, wherein a guide pipe and two groups of water inlet square pipes are fixedly installed on the upper part of the upper shell in a penetrating mode; a booster pump is fixedly installed on the upper part of the upper shell; one end of the booster pump is fixedly connected with the external end of the guide pipe; a water outlet pipe is fixedly installed on the inner bottom surface of the lower shell in a penetrating manner; a water spraying tank is fixedly installed at one end of the water outlet pipe in a sleeving manner; a plurality of groups of fixed through holes are formed in the lower part of the water spraying tank; I-shaped pipes are installed in the plurality of groups of fixed through holes in a penetrating manner; adjusting sealing plates are arranged at the external ends of the plurality of groups of I-shaped pipes; and scraping filter screens are slidably installed in the built-in ends of the two groups of water inlet square pipes. The spraying and dipping equipment for the catalyst provided by the invention has the beneficial effects that through the adjusting sealing plates, multiple groups of electromagnetic valves do not need to be additionally arranged to control liquid spraying, meanwhile, liquid flowing can be stopped in time, and the spraying and soaking device used for the catalyst conforms to the green and environment-friendly development concept.

Description

technical field [0001] The invention relates to the field of louver fans, in particular to a spraying and immersion equipment for catalysts. Background technique [0002] The impregnation method is a method widely used in the catalyst industrial production at present. The impregnation method is based on the principle that the active component (including the co-catalyst) is impregnated on the porous carrier in the form of a salt solution and penetrates into the inner surface to form a high-efficiency catalyst. To ensure the normal operation of the impregnation method, it is necessary to cooperate with the spraying and immersion equipment for the catalyst to spray out the liquid so that the liquid can be impregnated on the porous carrier and penetrate into the inner surface. The actual use of the spray and immersion equipment for the catalyst has the advantages of simple operation, penetration Good effect and stable use. [0003] However, the existing spraying and immersion e...

Problems solved by technology

[0003] However, the existing spraying and immersion equipment for catalysts has the following problems in application: the liquid injection port of the spraying and immersion equipment for catalysts does not use valves to control the liquid outflow, and it will not be able to stop the liquid in time. Electromagnetic valves are used to control the liquid outflow. This structure will increase the use cost of the spraying and immersion equipment used for catalysts, which does not conform to the concept of green and environmental protection development. Secondly, in order to prevent impurities in the liquid from blocking the liquid injection port, filter the impurities in the liquid in the form of a filter. A large amount of impurities will accumulate The liquid inlet is blocked, which affects the liquid inlet speed of the spraying and immersion equipment used for catalysts. Finally, there are many connection structures of the combined shells, so the weight is relatively large. Lifting part of the shell, lifting the shell will consume the physical strength of the operator, resulting in inconvenience in disassembly and assembly operations
