Description
Technical field
The application relates to the tubular heat exchanger technical field of heat-exchange energy-saving device-specific of petroleum refining and chemical industry, Coal Chemical Industry, chemical fertilizer industry, air-conditioning, air cooling, electric power facility, particularly relates to heat exchanger diaphragm seal weld seam buster and cutting method.
Background technology
In prior art, tubular heat exchanger is a kind of heat exchanger be most widely used, be widely used in the convection heat transfer' heat-transfer by convection of " liquid---liquid " in the fields such as chemical industry, oil, medicine, food, light industry, metallurgy, coking, " vapour---vapour ", " vapour---liquid " heat exchange, and the heat exchange condensation flow process such as steam-condensation and liquid evaporation heat transfer.
Tubular heat exchanger of the prior art is made up of main members such as tube bank, shell and bobbin carriages usually, wherein, bobbin carriage is the vitals of tubular heat exchanger, generally speaking, the pressure and temperature of tube side is all higher than shell side, and bobbin carriage is connected to heat exchanger tube and the tube sheet of tube bank in less structure space, tube side is imported and exported and dividing plate, stressed complexity, the easy deformed damaged of part, causes in high parameter medium and leaks or leak outside.The tubular heat exchanger of HTHP of the prior art, inflammable and explosive or poisonous medium, in order to avoid the leakage of flow process material, even if it imports and exports adapter, bore is very little, is usually also designed to the mode of the direct butt welding with pipeline, and does not adopt the mode of Flange joint; Equally, in order to avoid the leakage of flow process material, also weld between the shell of bigbore tube sheet and its both sides and bobbin carriage cylinder, so, bobbin carriage end just can not with also adopt the mode of welding between end cap, mainly consider and facilitate maintainer can enter to carry out the first-class repair work of detector tube from bobbin carriage end.
Thereupon, people are devoted to the research of the better hermetically-sealed construction between bobbin carriage end with bobbin carriage end cap except welded seal is connected always, sphere diaphragm seal technology is arisen at the historic moment, namely the sphere diaphragm seal dish of the increase between bobbin carriage end and bobbin carriage end cap, this sphere diaphragm seal dish is the hermetically-sealed construction of a shallow arch, specifically includes the plain cushion side ring being arranged at middle sphere diaphragm and the globally outer circumferential sides setting of diaphragm; Without the need to welding between bobbin carriage end and bobbin carriage end cap, but plain cushion side ring and bobbin carriage end are sealed by weld seam; Middle sphere diaphragm can along with the fluctuation of pressure Flexible change between arch and plane two kinds of versions, and when increasing from its overall diameter during arch complanation, when replying arch from plane, its overall diameter reduces.Like this, owing to have employed seal weld between plain cushion side ring and bobbin carriage end, and the radial deformation compensation rate of sphere diaphragm seal dish under HTHP effect and tube case end bore are to the uniformity of port displacement, solve above-mentioned inharmonic problem of expanding with heat and contract with cold preferably, there is good seal performance, structure is simple, the manufacturing cycle is short, low cost and other advantages.
But, owing to have employed seal weld between the side ring of sphere diaphragm seal dish and bobbin carriage end, inconvenience is brought to the repair and maintenance of bobbin carriage inside, needs are caused to carry out removal work for seal-weld, if use common fire to cut or abrasive machine polishing cutting, medium remaining in structure of not only igniting, also easily damage bobbin carriage end and barrier film advance capital for body, to re-assemblying bobbin carriage end and barrier film pad causes difficulty, therefore, in order to apply sphere diaphragm seal technology better, be necessary to avoid the technology adopting fire to cut or abrasive machine polishing is cut to remove the generation of the above-mentioned technical problem that seal-weld causes.
