Background

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 porosity is low, 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 the filler exists among the above-mentioned prior art tower equipment, the utility model provides a not only proportion is little, intensity is higher, acid and alkali-resistance, and specific surface is big moreover, the space is high, the good snowflake combined ring of gas-liquid exchange contact.

The utility model discloses the technical scheme who takes that has the technical problem of solution is: the snowflake combined ring comprises a ring body, wherein the ring body is formed by one-step pressing and firing of a ceramic material and is formed by high-temperature firing, the ring body comprises a regular-hexagon inner ring body located at the center of the ring and six regular-hexagon outer ring bodies connected with the six sides of the inner ring body in a shared mode, inner teeth which are as high as the ring body in height are arranged on the inner surface of each ring wall of the inner cavity of each of the inner ring body and the outer cavity of each outer ring body, a through hole is formed in one outer convex edge of each outer ring body, the through holes are rectangular holes with two semicircular ends, the width of each inner tooth is the same as the wall thickness of each outer ring body, the area of each through hole is 60-70% of the area of the ring wall where the through hole is located, and the ratio of the length to the width of each through hole is 2-2.5: 1.

The invention is characterized in that the inner ring body and the outer ring body are sequentially arranged from the center to the periphery, the inner surface of the ring wall of the inner ring body and the inner surface of the outer ring body are both provided with inner teeth, the outer ring body is provided with a waist-shaped through hole on an outer convex edge with two convex angles, and the wall thickness, the size and the arrangement position of the through hole are optimally designed, so that the inner cavity of the outer ring body can be in boundary with the outside, the specific surface area and the void ratio of the ring body can be improved, the pressure drop in a tower is reduced, the liquid flowing speed is accelerated, gas and liquid can be fully contacted with the ring body, and the gas-liquid exchange, filtration and purification effects can be improved.

Snowflake combined ring crisscross stack when using forms gas-liquid exchange transmission layer in tower equipment, and liquid can form the homodisperse on the interface, orderly continuous unblocked and steady transition's mobile state, not only can improve the specific surface area and the mechanical strength of filler, and enable liquid and carry out the intensive dispersion between the buckled plate filler and flow in order, reduce flow resistance, thereby not only make liquid keep suitable flow velocity between the buckled plate filler layer, and can make the mobile distribution of liquid on whole filler 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. Under the same shape and size, the weight is reduced by more than 50 percent, the load of tower equipment can be greatly reduced, the tower material and energy consumption are saved,

2. the same specification can increase the specific surface area by 20-30%, and the specific surface area can reach 150-²/m³The void ratio reaches 70 to 80 percent,

3. 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,

4. 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.
