Abstract

The invention discloses a processing method for a corrosion-resistant filler. The processing method comprises the steps of blending, crushing, mixing and ball grinding, water addition, clay preparation, forming, low-temperature drying, feeding into a kiln, firing and the like. According to the processing method, raw materials are mixed and ball-ground after being crushed in a filler processing process, so that crushing efficiency is improved, and the raw materials can be rapidly processed into required particle sizes; the surface of the filler is spray-coated with 1Cr13 and pure aluminum coatings, so that the corrosion resistance and the strength of the filler are further improved.

Description

technical field

[0001] The invention relates to a processing method for corrosion-resistant packing, which belongs to the technical field of petrochemical mass transfer and separation equipment. Background technique

[0002] In chemical engineering, packing refers to inert solid materials installed in packed towers, such as Pall rings and Raschig rings, etc., whose function is to increase the contact surface of gas-liquid and make them strongly mix with each other. Bulk packing is a granular body with a certain geometric shape and size, which is generally piled up in the tower in a random manner, also known as random packing or granular packing. According to different structural characteristics, bulk packing can be divided into ring packing, saddle packing, ring saddle packing and spherical packing.

[0003] At present, the packed tower has been widely used in unit operations such as rectification, absorption, extraction, etc. in chemical, petroleum, pharmaceutical, environ...
