Embodiment

[0017] The ceramic filler of the present embodiment is made from the raw material of following parts by weight: 10-12 parts of sepiolite, 10-12 parts of medical stone, Al 2 o 3 AlN powder 8-10 parts, AlN powder 4-5 parts, wollastonite 2-3 parts, diopside 3-4 parts, black talc 6-8 parts, magnesite 1-2 parts and clay 46-56 parts.

[0018] The processing method of the ceramic filler of the present embodiment is:

[0019] (1) Pulverization: use a pulverizer to pulverize the above-mentioned raw materials separately, and the particle size of the pulverized raw materials is between 10mm-15mm;

[0020] (2) Mixing ball milling: put the raw materials into the mixing ball mill according to the stated weight parts for mixing ball milling, the particle size of the raw materials after mixing ball milling is between 6250-8000 mesh;

[0021] (3) Add water: add water to mix the raw materials after ball milling, and the moisture content of raw materials after adding water is 15%-17%;

Abstract

The invention discloses a ceramic filler. The ceramic filler is prepared by the following materials in parts by weight: 10-12 parts of sepiolite, 10-12 parts of medical stone, 8-10 parts of Al2O3 power, 4-5 parts of AlN powder, 2-3 parts of wollastonite, 3-4 parts of diopside, 6-8 parts of black talc, 1-2 parts of magnesite and 46-56 parts of clay. The ceramic filler disclosed by the invention has the advantages that since the sepiolite, the medical stone and the black talc are added, the prepared filler has extremely-strong adsorptivity, so that the wetting for the filler can be easier, the mass-transferring performance can be improved and further the production efficiency can be improved.

Description

technical field [0001] The invention relates to a ceramic filler, belonging 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, environmental protection and other industrial ...
