Abstract

The utility model relates to a tubular-typed reactor of internal composite metal-wire netting, which is composed of an upper head, a bottom head, a casing, and two tube sheets on the two ends. The utility model is characterized in that the heat exchange tube which is connected with the tube sheets of the two ends is an inner composite wire mesh tube. The inner composite wire mesh tube is a multi-layer wire mesh tube with a certain number of holes which is bonded on the internal face of the metal tube. The utility model can be widely used in the chemical industry, the food industry, the light industry, the medical industry, etc.

Description

Tubular-type reactor of internal composite metal-wire netting

The utility model relates to a kind of interior 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 in adopting 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 interior 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 interior clad metal wire webmaster as shell and tube reactor, the clad metal wire webmaster is that inner surface pressure welding at metal tube becomes certain hole purpose multilayer (preferred 1-5 layer) woven wire in said, 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 inner surface 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 inner surface 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 interior clad metal wire webmaster, and 6 is upper cover.

Fig. 2 is the schematic perspective view of the interior clad metal wire webmaster that adopts in the utility model, 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 last, low head (6,1), housing (4), two ends tube sheet (2,5) the interior 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 be a kind of in the clad metal wire webmaster, in said the clad metal wire webmaster be exactly metal pipe internal surface 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, clad metal wire webmaster generally is to adopt after the first pressure welding manufacturing of volume soldering method to form said pressure welding here and the volume weldering is to realize easily for a person skilled in the art in this.

Claims

1, a kind of interior 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) be a kind of in the clad metal wire webmaster, said in the clad metal wire webmaster be exactly metal pipe internal surface 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, device according to claim 1 is characterized in that having the 1-5 layer to have certain hole purpose woven wire in the inner surface pressure welding of heat exchanger tube.
