Embodiment 1

[0016] Example 1, such as figure 1 with figure 2 As shown, the integral ceramic wire mesh corrugated packing includes a packing body 1, and the packing body 1 is provided with corrugated holes 2 at intervals. The cross section of the holes is triangular, which can be circular, regular hexagonal or square. Formed with honeycomb hole 3 on the hole wall 4 between, it is manufactured by following method step:

[0017] a. Select different 100-200 meshes of cellular polyurethane sponge (cuboid, or cube), fix the sponge, and clamp the upper and lower sides of the sponge to a suitable degree of firmness with mechanical splints. The thickness of the sponge body, on the side of the thickness, according to the preset hole size and position and the number of rows of holes, to maintain a suitable hole wall thickness between the holes, the size, quantity and distribution of the triangular file and according to tightness The size, position and row number of the holes converted by the comp...

Embodiment 2

[0027] Embodiment 2, except that the slurry in embodiment 2 is different from the slurry proportioning in Example 1, other preparation methods are the same as in Example 1, and the slurry in Example 2: use calcined aluminum oxide powder 40wt %, silicon dioxide powder 40wt%, water-washed high-purity kaolin 10wt%, phosphoric acid with a concentration of 85% by weight 3wt%, potassium chloride 1wt%, white carbon black 2wt%, micron-sized ceramic reinforcing agent 2wt%, micron-sized Bentonite 2wt% and appropriate amount of water are mixed and ball milled to make a slurry.

[0028] The monolithic ceramic wire mesh corrugated filler performance index that embodiment 2 makes:

[0029] Compressive strength: 16.3MPa, bulk specific gravity: 201.5kg / m 3 ,

[0030] Specific surface area: 800m 2 / m 3 , porosity: 91%,

[0031] Density: 1.52g / cm3, acid and alkali resistance: 99.5%.

Abstract

The invention discloses integrated type ceramic silkscreen corrugated packing which is prepared from a packing body, wherein a plurality of layers of corrugated holes are arranged on the packing bodyat intervals. A manufacturing method of the packing comprises the steps: choosing different meshes of cellular polyurethane sponge bodies, fixing the sponge bodies, utilizing mechanical clamping plates to clamp the sponge bodies to the appropriate positions with certain compactness, utilizing an automatic manipulator to make a file body of a stainless steel file perpendicularly drill holes to formholes on the sponge bodies, dipping the sponge bodies into slurry, then drying the sponge bodies which are evenly coated by the ceramic slurry in the sun, solidifying and shaping the dried sponge bodies which are dipped in the slurry and sending the dried sponge bodies into a natural gas shuttle type kiln to be sintered. The weight of the packing disclosed by the invention is only 30% of traditional ceramic corrugated packing; furthermore, the problems that traditional metal regular packing has poor corrosion resistance and hydrophilic performance. The packing disclosed by the invention has ahigh separation and rectification efficiency and low flow resistance, can remarkably reduce equipment construction and equipment operation cost of enterprises and achieves production increasing, benefit improvement, energy conservation and emission reduction for the enterprises.

Description

technical field [0001] The invention relates to a ceramic corrugated packing, in particular to an integral ceramic wire mesh corrugated packing. Background technique [0002] At present, there are many kinds of fillers used in drying towers, washing towers, absorption towers and rectification separation towers used in chemical, petrochemical, pharmaceutical, pesticide and other industries. The corrugated flow channels on the top are linear and vertically staggered, so the flow direction of the liquid between the packing layers will change, so that the flow speed of the liquid between the packing layers will be accelerated, and the flow resistance will be reduced, thereby improving the separation of liquid distillation. Effect. Therefore, corrugated packing is mostly used in the rectification separation column. At present, the corrugated plate packing is made of stainless steel wire mesh welded wire mesh corrugated packing, ceramic corrugated structured packing made of cera...
