Technical Field

The utility model belongs to the technical field of the chemical industry, concretely relates to tubulation bearing structure of grid formula.

Background

The shell-and-tube heat exchanger is also called a tube-type heat exchanger, and is a dividing wall type heat exchanger which takes the wall surface of a tube bundle sealed in a shell as a heat transfer surface. The heat exchanger has simple structure, low cost, wide flow cross section and easy scale cleaning.

The tube support of shell-and-tube heat exchanger is usually baffle plate support, and the baffle plate is divided into single arch, double arch and ring. Baffle formula bearing structure is simple, and convenient the manufacturing, nevertheless to the little operating mode of resistance requirement, baffle formula support just hardly satisfies the technological requirement.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems existing in the prior art, the utility model aims to provide a tubulation bearing structure of grid formula that medium resistance is little.

The utility model discloses the technical scheme who adopts does:

a grid type array tube supporting structure comprises a ring plate cylinder section, wherein two layers of grid plates are connected in the ring plate cylinder section, and an array tube penetrates through a quadrilateral space formed by two adjacent grid plates on the upper layer and two adjacent grid plates on the lower layer in a surrounding mode.

A plurality of small quadrilateral areas can be enclosed between the upper grid plate and the lower grid plate, and then the tubes can pass through the quadrilateral areas, so that the tubes are supported. The size of the quadrangle can be changed by adjusting the included angle between the upper grid plate and the lower grid plate and the distance between the adjacent grid plates on the same layer, so that the novel grid plate is suitable for the tubes with different diameters. Because the gaps between the grating plates are large, the medium flow area is large, and the resistance is small; the grating plate is thin, the span is large, and the pipe penetration is easy.

As the preferred scheme of the utility model, a plurality of grid boards in upper strata are parallel to each other, and a plurality of grid boards in lower floor are parallel to each other. The grid plates on the same layer are parallel to each other, so that the size and the shape of a plurality of quadrangles formed by the upper grid plate and the lower grid plate are the same, and a plurality of tubes are conveniently supported.

As the preferred proposal of the utility model, the included angle between the upper layer grid plate and the lower layer grid plate is 30-90 degrees. And a certain included angle is formed between the upper grid plate and the lower grid plate, so that the outer wall of the tube nest can be contacted with the grid plates, and the tube nest can be reliably supported.

As the preferred proposal of the utility model, the included angle between the upper grid plate and the lower grid plate is 60 degrees. When the included angle between the upper grid plate and the lower grid plate is 60 degrees, the tubes are stably supported, and proper intervals are kept among the tubes.

As the preferred scheme of the utility model, the both ends of grid board all weld in the inner wall of circle board shell ring. The grid plate is welded on the inner wall of the ring plate cylindrical shell section, so that the stability of the grid plate is ensured.

As the preferred proposal of the utility model, the upper grid plate and the lower grid plate are not welded. The upper grid plate and the lower grid plate are not welded, so that stress deformation is avoided.

As the preferred scheme of the utility model, the grid board is the sheet metal, and the narrowest limit level of grid board sets up. The grid plate is vertically arranged, so that the grid plate is not easy to bend.

The utility model has the advantages that:

the utility model discloses a can enclose into a plurality of little quadrangle regions between upper grid tray and the lower floor's grid tray, then the tubulation can follow the quadrangle region and pass for the tubulation obtains the support. The size of the quadrangle can be changed by adjusting the included angle between the upper grid plate and the lower grid plate and the distance between the adjacent grid plates on the same layer, so that the novel grid plate is suitable for the tubes with different diameters. Because the gaps between the grating plates are large, the medium flow area is large, and the resistance is small; the grating plate is thin, the span is large, and the pipe penetration is easy.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 to 4, the grid-type tube nest support structure of the present embodiment includes a ring plate cylinder section 1, two layers of grid plates 2 are connected in the ring plate cylinder section 1, and a tube nest 3 passes through a quadrilateral space defined by two adjacent grid plates 2 on the upper layer and two adjacent grid plates 2 on the lower layer.

A plurality of small quadrilateral areas can be enclosed between the upper grid plate 2 and the lower grid plate 2, and the tubes 3 can penetrate through the quadrilateral areas, so that the tubes 3 are supported. The size of the quadrangle can be changed by adjusting the included angle between the upper grid plate 2 and the lower grid plate 2 and the distance between the adjacent grid plates 2 on the same layer, thereby being suitable for the tubes 3 with different diameters.
