Currently, there are various fillers used in reaction apparatuses such as saturation towers, cooling towers, absorption towers, etc. in the industries of chemical industry, petrochemical industry, environmental protection, gas industry, etc., and the fillers refer to materials filled in other objects. In chemical engineering, the filler is an inert solid material which is filled in a packed tower and has the function of increasing the gas-liquid contact surface and enabling the gas-liquid contact surface and the inert solid material to be mixed strongly with each other. In chemical products, the filler is also called filler, which is a solid material for improving processability and mechanical properties of products and/or reducing cost. In the field of sewage treatment, the method is mainly used for a contact oxidation process, and microorganisms can be accumulated on the surface of a filler to increase the contact with the surface of sewage so as to degrade the sewage. According to the comprehensive technological requirements of various aspects of reaction temperature distribution, pressure drop, gas-liquid property, reaction efficiency, operation working cost and the like in tower equipment, the filler in the tower equipment is required to have high strength and good acid and alkali resistance, and is required to have high porosity, large specific surface area, uniformly dispersed cross section pores and light weight. At present, the packing in the reaction equipment mainly comprises wire mesh packing and ceramic structured packing. Although the wire mesh fillers have the characteristics of high strength and good acid and alkali resistance, the wire mesh fillers have the following disadvantages: firstly, due to the limitation of the structure, the void ratio is not high, the specific surface area is small, the pressure drop in the reaction equipment is overlarge, the flow resistance of reactants is increased, and the effective contact frequency of the reactants is reduced, so that the reaction effect and efficiency of the reaction equipment are influenced; secondly, although the ceramic structured packing has uniform gas-liquid flow direction dispersion and higher porosity, the ceramic structured packing has single liquid flow direction, higher stacking density, higher flow resistance and poor gas-liquid exchange effect.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the above-mentioned prior art, the utility model provides a not only intensity is high, acid and alkali-resistance, and specific surface is big moreover, the space is high, and the porous whirl ring that the gas-liquid exchange contact is better packs.
The utility model discloses the technical scheme who takes that has the technical problem of solution is: the ceramic material once extrusion molding for the porous rotational flow ring packing comprises a packing body, wherein the packing body comprises a middle ring body positioned at the center of the packing body, an outer ring body respectively connected with the periphery of the middle ring body and an inner ring body positioned in the middle ring body and the outer ring body, the middle ring body, the outer ring body and the inner ring body are all regular hexagonal frame bodies, wheel spokes are respectively arranged on the diagonal lines of the outer ring body and the inner ring body and the diagonal lines of the middle ring body and the inner ring body, a convex body is arranged on the end face of the outer ring body, an inner flow hole is formed in the inner ring body, a trapezoidal annular flow hole is formed between the outer ring body and the inner ring body, and a through hole with a trapezoidal cross section is formed in the convex body.
Furthermore, the ratio of the wall thickness of the outer side surface of the outer ring body to the wall thickness of the inner ring body is 1.2-1.5, the ratio of the wall thickness of the inner ring body to the thickness of the spoke plate is 1-1.1, and the ratio of the diameter of the inscribed circle of the inner ring body to the diameter of the inscribed circle of the outer ring body is 0.5-0.6.
Pack crisscross when using and build and add in tower equipment, form gas-liquid exchange transmission layer, the dispersion on the interface of the even exchange of multiple gas-liquid that utilizes the boss to form, and outer annular ring, the water conservancy diversion effect in wind annular ring, make liquid can form the homodisperse on the interface, orderly continuous unblocked and steady transition's whirl state, not only can improve the specific surface area and the mechanical strength of packing, and enable liquid and carry out the orderly whirl of intensive dispersion between packing, reduce the flow resistance, thereby not only make liquid keep suitable flow velocity between the packing layer, and can make the flow distribution of liquid on whole packing layer even, make liquid form liquid drop or liquid film and gaseous abundant contact, thereby improve the liquid absorption effect.
Compared with the prior ceramic regular packing, the utility model has the advantages that
1. The same specification can increase the specific surface area by 20-30%, and the specific surface area can reach 200-300m2/m3The void ratio reaches 70 to 80 percent,
2. the utility model has compact structure, neat and orderly stacking arrangement, mutual separation between the stacking layers, small gas-liquid flow resistance, even and orderly flow dispersion, good absorption and separation effect,
3. the utility model discloses the suitability is strong, and application range is wide, can be used to wash tea in the chemical tower equipment, wash benzene, wash ammonia and desulfurization, decarbonization and cooling and absorption.
