Description

Curved rotational flow structured packing

Technical Field

The utility model relates to an industrial tower is with packing, especially, relate to a regular packing of curved shape whirl.

Background

There are various fillers used in reaction apparatuses such as saturation towers, cooling towers, absorption towers, etc. for washing, desulfurization, decarburization, etc. in industries such as chemical, petrochemical, environmental protection, gas, etc., and the filler means a material 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. 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 tower equipment mainly comprises wire mesh packing and ceramic regular 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 filler exists among the above-mentioned prior art in the tower equipment, the utility model provides a not only intensity is higher, the proportion is little, acid and alkali-resistance, and specific surface is big moreover, the space is high, the regular filler of a curved shape whirl that the gas-liquid exchange contact is good.

The to-be-solved technical problem of the utility model is that: the utility model provides a curve shape whirl is regular for packing plastics one shot injection moulding, it includes the filler body, the filler body is including the inner ring body that is located the filler body center and encircle a plurality of outer rings body at inner ring body periphery, inner ring body and outer rings body are regular hexagon framework, each limit of inner ring body links to each other with outer rings body one side coparallel respectively, adjacent outer rings body links to each other with the coparallel, inner ring body and outer rings body are internal to be staggered and are provided with the spoke body, the spoke body is S-shaped plate form, the spoke body divides into a plurality of interior discharge orifice and a plurality of reposition of redundant personnel hole with inner ring body inner chamber and outer rings body inner chamber respectively, spoke body both ends and outer rings body or inner side smooth connection, the spoke body is crossing at inner ring body or outer rings body center, spoke body thickness is less than inner.

Pack crisscross when using and build and add in tower equipment, form gas-liquid exchange biography layer, be the same as with interior ring member and outer ring body inner chamber design for the interior discharge orifice of many S curvilinear figures and reposition of redundant personnel hole, make liquid can form homodisperse on the interface, orderly continuous unblocked and steady transition' S whirl state, not only can improve the specific surface area void fraction of packing, and because the effect of the curved wheel spoke body, 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 15-20%, and the specific surface area can reach 150-²/m³The void ratio reaches 70 to 75 percent,

2. the utility model has compact structure, neat and orderly stacking and arrangement, mutually staggered arrangement of the lamination 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.
