Embodiment Construction

[0010] Referring to Fig. 2, the sides of every two corrugated plates 16 are welded to form a plate bundle 8 to form an I flow channel, and then the two plate bundles are welded together to form an II flow channel between each two plate bundles, and finally multiple The end faces of each plate bundle are sealed together with the casing filler 7 (see Figure 3) to form a complete machine. As can be seen from Figure 1, the heat exchanger is composed of lifting ring 1, medium II outlet flange 2, clamping bolt, nut 3, medium I inlet flange 4, compression bolt 5, sealing bead 6, packing 7, plate bundle 8. Frame 9, partition 10 (baffle plate), medium II inlet flange 13, medium I outlet flange 14, anchor 15 and other main components, medium I enters the plate bundle from the inlet flange 4 Enter the next plate bundle through the partition, etc., and come out from the medium I outlet flange to form a flow channel. The medium II enters the plate bundle from the medium II inlet flange an...

Abstract

The invention provides a half-detachable welding plate type heat exchanger. The technical problems needed to be solved are as follows: the prior plate type heat exchanger widely uses rubber pad to seal, and the rubber pad can not be used in the medium which has corrodibility to the rubber pad. While the tube type heat exchange also has the defects of low heat transmission efficiency, inconvenient demounting and cleaning, etc, and the complete welding plate type heat exchanger is not detachable. The half-detachable welding plate type heat exchanger has the key points that a plate bundle is welded by the lateral sides of every two corrugated plates, and a I flow channel is formed. Two plate bundles are welded together, and an II flow channel is formed between the lateral sides of every two plate bundles. At last, end faces on the same side of a plurality of plate bundles and the casing fillers are sealed together, and a complete machine is formed. The half-detachable welding plate type heat exchanger has the purpose that the half-detachable welding plate type heat exchanger is suitable for being used for the heating and cooling of the process medium in industries of petroleum, chemical, electricity, metallurgy, medicine and so on.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a welded plate heat exchanger. Background technique [0002] The existing plate heat exchangers are generally sealed with rubber gaskets, so that the operating pressure of the plate heat exchanger can only be lower than 2.0MPa, and the operating temperature is less than 200°C. It cannot be used in the medium that is corrosive to the rubber pad, which limits the scope of use of the plate heat exchanger. The tubular heat exchanger has disadvantages such as low heat transfer efficiency, inconvenient disassembly and cleaning, while the fully welded plate heat exchanger is not detachable, and has strict requirements on the cleanliness of the medium used. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a kind of high temperature resistance, pressure resistance, corrosion resistance, high heat transfer efficie...
