Problems solved by technology

However, since the material itself is hydrophobic, it is difficult for the water flow to form a water film on the surface of the material, but flows down in the form of water droplets or strands, so the increase rate of the gas-liquid contact area is small, resulting in low heat and mass transfer efficiency.
[0004] Metal packing has poor corrosion resistance and cannot be used in alkaline, acidic and salt solution environments for a long time
[0005] Paper packing not only has poor strength and odor, but also has the problem of glue dissolution / decomposition in a liquid environment for a long time, which leads to shrinkage, looseness, and slag drop of the packing sheet, and leads to a decrease in heat and mass transfer efficiency.

Abstract

The invention discloses a gas-liquid heat transfer device based on ceramic matrix composite resin filler and a filler preparation method. In the filler, resin fibers and heat-conducting fibers are added into a ceramic matrix to form the high-efficiency ceramic composite resin corrosion-resistant filler. Compared with common filler, the ceramic composite resin corrosion-resistant filler is better in tensile strength and flexibility, better in heat-conducting property and higher in corrosion resistance.

Description

technical field [0001] The invention relates to the field of fillers, in particular to a gas-liquid heat transfer device based on ceramic matrix composite resin fillers and a preparation method for the fillers. Background technique [0002] At present, the packings used in industry are mainly corrugated packings, annular packings and saddle packings. Corrugated packing is assembled from multiple single-layer corrugated packing sheets. According to the structure, corrugated packing can be divided into wire mesh corrugated packing, plate corrugated packing, pulse corrugated packing, etc., and its material can be divided into paper, metal, plastic and ceramics. Rings and saddles include Raschig rings, Pall rings, stepped rings, saddle rings, etc., and their materials are divided into metal, plastic and ceramics. [0003] Most of the above-mentioned plastic fillers increase the uniformity of liquid distribution on the surface of the filler by pressing various small holes, fine...
