A non-welded double-seal quick disassembly steam heat exchanger and its realization method

Abstract

The invention discloses a non-welding double-seal rapid disassembling and assembling type steam heat changer comprising an upper closed cover, heat exchanger main body sets and a lower closed cover. The upper closed cover and the lower closed cover are arranged at the upper ends and the lower ends of the heat exchanger main body sets correspondingly, and circular sealing strips are arranged between the heat exchanger main body sets and the upper closed cover as well as between the heat exchanger main body sets and the lower closed cover. The non-welding double-seal rapid disassembling-assembling type steam heat changer has the following advantages that the steam heat exchanger adopts the non-welding double-seal rapid disassembling and assembling type and is prevented from rusting, the heatexchange effect is fully improved, and the steam leakage phenomenon is avoided; the cost is reduced, and the maintenance time is saved; and scrapping of the steam heat changer is avoided, and socialresources are saved.

Description

technical field [0001] The invention relates to a steam heat exchanger, in particular to a non-welded double-seal quick disassembly steam heat exchanger and a realization method thereof. Background technique [0002] We need mountains of gold and silver, but also green mountains and clear waters. This is the growing demand of the people for a better life. The heating methods of small boilers and small coal furnaces have become a passer-by in history. The thermal power company uses environmentally friendly equipment to produce qualified steam, which is uniformly supplied to all users. Each user uses a steam heat exchanger to convert it into a heat source for their own needs. In this context, the traditional welded steam heat exchanger is no longer applicable due to frequent steam leakage due to weld cracking, and the non-welded double-sealed quick-disassembly steam heat exchanger has emerged as the times require. [0003] The traditional steam heat exchanger is made by weldi...

Problems solved by technology

In this context, the traditional welded steam heat exchanger is no longer suitable for frequent steam leakage due to weld cracking, and the non-welded double-sealed quick-disassembly steam heat exchanger has emerged as the times require

[0003] The traditional steam heat exchanger is made by welding. Because the steam temperature is very high (about 200°C), the metal tube (plate) expands and contracts with heat and shrinks and deforms, resulting in cracking of the weld seam, resulting in steam leakage, and cracking after welding maintenance , leading to frequent occurrence of steam leakage, in most cases, it is better to replace it with a new one than to repair it, resulting in the scrapping of the steam heat exchanger, resulting in a waste of a lot of social resources
