Abstract

The utility model discloses a cylindrical packing for a filter screen, which comprises a cylindrical frame composed of an upper ring body (2), a middle ring body (9), a lower ring body (10) and an upright column (6), and a middle rack positioned inside the cylindrical frame, wherein the middle rack has one or two layers, each of which is composed of 4-8 uniformly distributed transverse bars (8) and a central ring body (3), the upright column is arranged between the upper and the lower ring bodies at the joint site of the outer end of the transverse bar and the middle ring body, a sheet rib (1) and a diagonal bar (7) are alternately and respectively arranged at the intersection sites of the transverse bars and the upright column, a grid ring body (5) is respectively arranged in the window holes formed between the upright column and the upper ring body and between the middle ring body and the lower ring body, an external ring body (4) is arranged on the external surfaces of the upper, the middle and the lower ring bodies, so as to form a reticular structure of the packing, increase gas-liquid mass transfer flux, reduce pressure drop resistance, avoid the phenomena of wall flow, channeling and adhesion of suspended matters in the tower, and enable the gas-liquid mass transfer distribution to be more uniform. The cylindrical packing for the filter screen in the utility model not only improves washing, absorbing and cleaning effects, but also reduces the load of the tower, facilitates installation and prolongs the service life of the tower packing.

Description

The filter screen filler

Technical field

The utility model relates to the filler that industry towers such as being used for metallurgy, chemical industry, environmental protection and electric power uses, and relates in particular to be used for filter screen filler metallurgical and that the chlorine industry tower uses.

Background technology

Along with the packing technique that uses in metallurgical and the chlorine industry tower requires to improve constantly, originally the general filler of Shi Yonging is because flux is less, weight is big, the pressure drop resistance increases in the tower, the one, make to be easy to generate wall stream, channel in the tower and to stick the suspension phenomenon, cause gas, liquid mass transfer skewness phenomenon, the needs that exchange mutually in the time of can not satisfying gas, liquid mass transfer by filler well, thus washing, absorption and clean-up effect reduced; Be that the load-carrying of tower load is increased again, it is not too convenient that filler is installed, and the filler loss increases, and tower operation life cycle shortens.

The utility model content

At the problem that tower filler in the above-mentioned prior art exists, the utility model provides a kind of and not only washs, absorption and good purification and the long filter screen filler of life cycle.

The technical scheme that the technical problems to be solved in the utility model is taked is: described filter screen filler profile is cylindrical, it comprises by upper ring body, middle ring body, round framework that lower ring body and column form and the middle support body that is positioned at round framework, support body is 1 to 2 layer in the middle of described, be provided with middle ring body every layer of external side of middle frame, support body is formed by four to eight equally distributed horizontal bars and center ring body in the middle of described every layer, the horizontal bar outer end links to each other with middle ring body, horizontal bar the inner links to each other with the center ring body, between the upper ring body of horizontal bar outer end and middle ring body connecting place and lower ring body, be provided with column, be arranged at intervals with sheet muscle and diagonal bar respectively in horizontal bar upper surface and column intersection, be arranged at intervals with diagonal bar and sheet muscle respectively in horizontal bar lower surface and column intersection, at column and upper ring body, be provided with the grid ring body in the fenestra that middle ring body and lower ring body form, at upper ring body, lower ring body and middle ring body lateral surface are provided with outer ring body.

The utility model is formed by multiple ring body and middle frame body, it has network structure, hole is many, intensity is good, thereby gas, liquid mass transfer circulation increases, the pressure drop resistance reduces in the tower, can not produce wall stream in the tower, channel and stick the suspension phenomenon, gas-liquid mass transfer is more evenly distributed, the needs that exchange mutually in the time of satisfying gas-liquid mass transfer by filler have well not only improved washing, absorb and clean-up effect, and the utility model is in light weight, fitting operation is more convenient, the load-carrying of tower load reduces, thereby has prolonged tower filler life cycle, and the utility model has the result of use of similar filler inlet in tower fully.
