Embodiment Construction

[0012] Such as figure 1 As shown, a corrugated spiral plate heat exchanger includes a double spiral heat exchange plate 1 in a shell. The double spiral heat exchange plate is rolled by a flat steel plate 4 and a corrugated steel plate 3. There are fixed distance posts 2 welded on both sides. Such as figure 2 As shown, the corrugated steel plate is provided with a non-corrugated fixed-distance column welding area, and the fixed-distance column welding area is welded on both sides of the fixed-distance column welding area. The fixed distance column welding area is a non-corrugated strip along the length of the corrugated steel plate. 31. In order to make the plate spacing of the double helix heat exchange plate uniform after rolling, a plurality of non-corrugated belts are arranged on the corrugated steel plate, and each non-corrugated belt is arranged in parallel and equidistant; in order to facilitate the sealing of the ends of the double helix heat exchange plate, There are ...

Abstract

The invention discloses a corrugated spiral plate heat exchanger which comprises a dual-spiral heat exchanger in a shell, wherein the dual-spiral heat exchanger is formed by rolling a flat steel plate and a corrugated steel plate; the corrugated steel plate is provided with a non-corrugated spacing column welding zone; spacing columns are welded on the positive surface and negative surface of the spacing column welding zone; and the spacing column welding zone is a non-corrugated ribbon along the length direction of the corrugated steel plate. The heat exchanger has the advantages of simple structure, large heat exchange area and high heat exchange efficiency.

Description

Technical field [0001] The invention relates to a heat exchange device, in particular to a spiral plate heat exchanger. Background technique [0002] The spiral plate heat exchanger has the advantages of long heat transfer channels, large flow channel spacing, compact structure, etc. The spiral plate heat exchanger in the prior art mostly adopts two long flat steel plates stacked together and rolled into a double Spiral heat exchange plate, with fixed-distance columns uniformly welded on each steel plate. Because this spiral plate heat exchanger uses two flat steel plates to make a double spiral heat exchange plate, this spiral plate heat exchanger has the disadvantages of small heat transfer area and low heat exchange efficiency. Summary of the invention [0003] The technical problem to be solved by the invention is to provide a corrugated spiral plate heat exchanger with simple structure, large heat transfer area and high heat exchange efficiency. [0004] The technical solutio...
