Abstract

The utility model relates to a composited wire mesh pipe type reactor, comprising an upper head, a bottom head, a casing, and pipe sheets at the two ends. The utility model is characterized in that the pipe sheets at the two ends which are connected (welded) with the heat exchange pipe are composite wire mesh pipes. The composite wire mesh pipe is a multi-layer wire mesh pipe which bonds holes with a certain number on the inner and outer surface of the metal pipe. The utility model can be widely used for the chemical industry, the food industry, the light industry, the medical industry, etc.

Description

Composited wire pipe type reactor

The utility model relates to a kind of complex metal wire-mesh row-tube type reactor, belongs to the improvement of shell-and-tube reactor.

As everyone knows, shell and tube reactor is one of chemical industry common equipment, and its heat-transfer effect quality is one of leading indicator of weighing this reactor performance.At present, the heat exchanger tube that shell and tube reactor adopts mostly is the light wall metallic pipe, in order to improve its heat transfer efficiency, often also take some measures, for example, heat exchanging is carried out kerve, pit, is sprayed, adds wing etc., but adopt the complex metal wire-mesh pipe make shell and tube reactor do not appear in the newspapers so far to.

The purpose of this utility model is that a kind of improved shell and tube reactor will be provided, especially a kind of complex metal wire-mesh row-tube type reactor.It can overcome the existing not good drawback of being made by smooth wall pipe of shell and tube reactor heat-transfer effect.

The purpose of this utility model is achieved in that and adopts the heat exchanger tube of a kind of clad metal wire webmaster as shell and tube reactor, said clad metal wire webmaster is that the surfaces externally and internally pressure welding at metal tube becomes certain hole purpose multilayer (preferred 1-5 layer) woven wire, so not only can strengthen the heat transfer area of heat-transfer pipe, and can improve heat transfer efficiency greatly.

The utility model is because only need be at the certain hole of original heat exchanger tube surfaces externally and internally pressure welding multilayer (preferred 1-5 layer) purpose woven wire, so it is simple in structure, make easily, and compare with existing smooth wall shell-and-tube reactor, under the identical situation of other operating condition, its heat transfer efficiency can improve 3-8 doubly, and the utility model can be widely used in industries such as chemical industry, food, light industry, medicine.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is that wherein 1 is low head according to the structural representation of the surfaces externally and internally complex metal wire-mesh row-tube type reactor that the utility model proposes, and 4 is housing, 2,5 is the two ends tube sheet, welding heat exchanger tube 3 between two tube sheets, this heat exchanger tube is the clad metal wire webmaster, and 6 is upper cover.

Fig. 2 is the schematic perspective view of the clad metal wire webmaster that adopts in the utility model, and wherein 7 is the outer surface oven wire mesh blanket, and 8 is metal pipe-wall, and 9 is the inner surface oven wire mesh blanket.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

This device comprises by upper and lower end socket (6,1), housing (4), two ends tube sheet (2,5) the complex metal wire-mesh row-tube type reactor that is constituted, the heat exchanger tube 3 of (welding) of linking to each other with the two ends tube sheet is a kind of clad metal wire webmaster, said clad metal wire webmaster be exactly the metal tube surfaces externally and internally all pressure welding become certain hole order (preferably square hole or inclined hole, the preferred 30-120 order of order number) multilayer (preferred 1-5 layer) woven wire, this clad metal wire webmaster generally are that the manufacturing of volume soldering method forms after adopting first pressure welding.Here said pressure welding and volume weldering are to realize easily for a person skilled in the art.

Claims

1, a kind of complex metal wire-mesh row-tube type reactor, constituted by upper and lower end socket, housing, two ends tube sheet, it is characterized in that: the heat exchanger tube of link to each other with the two ends tube sheet (welding) is a kind of clad metal wire webmaster, said clad metal wire webmaster be exactly the metal tube surfaces externally and internally all pressure welding become to have the pipe of certain hole purpose multiple layer metal silk screen.

2, reactor according to claim 1 is characterized in that said wire mesh holes is square hole or inclined hole, and order is counted the 30-120 order.

3, reactor according to claim 1 is characterized in that having the 1-5 layer to have certain hole purpose woven wire in the surfaces externally and internally pressure welding of heat exchanger tube.
