Description

Heat exchanger diaphragm seal weld seam buster and cutting method
Technical field
This application involves petroleum refining and chemical industry, coal chemical industry, chemical fertilizer industry, air-conditioning, air-cooled, electric power facility heat exchange section The tubular heat exchanger technical field of energy device-specific, more particularly to heat exchanger diaphragm seal weld seam buster and excision side Method.
Background technology
In the prior art, tubular heat exchanger is a kind of heat exchanger being most widely used, and is widely used in chemical industry, stone In the field such as oil, medicine, food, light industry, metallurgy, coking " liquid --- liquid ", " vapour --- vapour ", " vapour --- liquid " heat exchange Convection current is conducted heat, and the heat exchange condensation flow such as steam condensation and liquid evaporation heat transfer.
Tubular heat exchanger of the prior art is usually made of main members such as tube bank, shell and bobbin carriages, wherein, bobbin carriage It is the important component of tubular heat exchanger, it is however generally that, the pressure and temperature of tube side is all higher than shell side, and bobbin carriage is in less structure The heat exchanger tube and tube sheet of tube bank, tube side inlet and outlet and partition plate are connected in space, stress is complicated, and part is easily deformed damage, draws Play leakage or leakage in high parameter medium.High temperature and pressure of the prior art, inflammable and explosive or poisonous medium tubular heat exchanger, In order to avoid the leakage of flow material, even if its inlet and outlet adapter bore very little, is also normally designed to and the direct butt welding of pipeline Mode, without by the way of flanged joint;Equally, in order to avoid the leakage of flow material, bigbore tube sheet and its both sides Shell and bobbin carriage cylinder between also welded, so, bobbin carriage end cannot between end cap also using welding Mode, being mainly in view of personnel convenient to overhaul can enter to be detected the repair works such as tube head from bobbin carriage end.
Therewith, people have been devoted to more preferable in addition to welded seal connects between bobbin carriage end and bobbin carriage end cap The research of sealing structure, sphere diaphragm seal technology are come into being, i.e., the increase between bobbin carriage end and bobbin carriage end cap one Sphere diaphragm seal disk, the sphere diaphragm seal disk are the sealing structures of a shallow arch, specifically include and are arranged at centre The plain cushion side ring that the outer circumferential sides of sphere diaphragm and globally diaphragm are set;Without being welded between bobbin carriage end and bobbin carriage end cap, But plain cushion side ring is sealed with bobbin carriage end by weld seam;Middle sphere diaphragm can be as the fluctuation of pressure be in arch and plane Flexible change between two kinds of structure types, when from arch complanation its overall diameter increase, when from plane reply arch when its Overall diameter reduces.In this way, due to employing sealing weldering between plain cushion side ring and bobbin carriage end, and sphere diaphragm seal disk is in high temperature Radial deformation compensation rate under high pressure effect, to the uniformity of port displacement, preferably solves above-mentioned heat expansion with tube case end bore The problem of shrinkage is uncoordinated, has the advantages that good seal performance, simple in structure, the manufacturing cycle is short, cost is low etc..
However, due to employing sealing weldering between the side ring of sphere diaphragm seal disk and bobbin carriage end, inside bobbin carriage Repair and maintenance brings inconvenience, results in the need for being removed work for seal-weld, if cut using common fire or sand Turbine polishing is cut, and remaining medium in the structure that can not only ignite, is also easy to damage bobbin carriage end and membrane advance capital for body, to again Assembling bobbin carriage end and membrane pad cause difficulty, therefore, in order to preferably promote and apply sphere diaphragm seal technology, it is necessary to keep away The technology for exempting to cut using fire or abrasive machine polishing is cut removes the generation of the above-mentioned technical problem caused by seal-weld.
The content of the invention
