Description
Technical field
The utility model belongs to petrochemical industry, relates to the corrosion resistant polytetrafluoroethyltubular tubular air preheater of a kind of low temperature.
Background technology
The present air preheater that uses at petroleum chemical industry is generally by the metal material manufacture.But when there was corrosivity in medium, the air preheater that traditional metal material is manufactured, obviously can not meet instructions for use.The method that solves mainly contains: (1) uses expensive metal material, and as titanium alloy etc., this can improve the manufacturing cost of air preheater greatly, and sometimes can not prevent the generation of corroding.(2) use the nonmetal graphite material, graphite material has good heat transfer property, and very strong decay resistance is arranged.But because graphite-pipe is fragile material, the stress brittle failure occurs easily, have been subject to certain impact in its reliability and service life.(3) use polyfluortetraethylene pipe to make heat transfer element, polytetrafluoroethylene (PTFE) has good decay resistance, but due to the stable performance of polytetrafluoroethylene (PTFE) chemistry, the more difficult control of the welding of tube and tube plate, because the Tube-sheet Welding technological principle of polytetrafluoroethylene (PTFE) is different from the steel heat exchanger Tube-sheet Welding, just also can't carry out the interior welds quality testing at present, can only be by the macroscopic examination means, as the water pressure test or air-tight test, determine the fastness of solder side.To the indivedual defects that exist on solder side, can't measure immediately, can only make regular check on and make up in use for some time.This has just affected the reliability of teflon heat exchanger application.
Patent CN200920022497.1 discloses a kind of high-efficient energy-saving polytetrafluoroethyltube tube type heat exchanger, comprise cylindrical shell, heat exchanger tube and closure member, heat exchanger tube is comprised of the graphite modified ptfe composite pipe that some Shu Binglie arrange, closure member comprises end socket, tube sheet and cover plate, the import and export of product medium are on end socket, heat exchanger tube is fixed on cylindrical shell with deflection plate, between heat exchanger tube and tube sheet, adopts metal bath high temperature hot melt expanded and welded tube joint to connect.But due to the stable performance of polytetrafluoroethylene (PTFE) chemistry, the more difficult control of the welding of tube and tube plate, airtight quality is difficult to guarantee.In addition, because the thermal coefficient of expansion of polytetrafluoroethylene (PTFE) is far longer than carbon steel, the thermal expansion in use can't discharge, and easily makes weld seam produce stress rupture, makes heat exchanger failure.
The utility model content
Poor for the tubular type teflon heat exchanger Tube-sheet Welding sealing that solves the prior art existence, the technical problem that medium is revealed easily occurs, the utility model provides a kind of polytetrafluoroethyltubular tubular air preheater.
The polytetrafluoroethyltubular tubular air preheater that the utility model provides mainly is comprised of gas approach section, exhanst gas outlet section, flue gas bobbin carriage, air intlet section, air outlet slit section, air bobbin carriage, clad tubesheet, polyfluortetraethylene pipe and black box; Gas approach section and exhanst gas outlet section are positioned at the two ends of flue gas bobbin carriage, with the flue gas bobbin carriage, are on same axis, and gas approach section, flue gas bobbin carriage and exhanst gas outlet section form exhaust gases passes; The flue gas bobbin carriage is interior for flue gas bobbin carriage axis, to be vertically arranged polyfluortetraethylene pipe, the air intlet section is connected with the air outlet slit section by polyfluortetraethylene pipe and air bobbin carriage, and air intlet section, polyfluortetraethylene pipe, air bobbin carriage and air outlet slit section form air duct jointly; Wherein black box is for the sealing between clad tubesheet and polyfluortetraethylene pipe, mainly by housing screw, stop sleeve, tight socket and sealing gasket, formed, pore and clad tubesheet that tight socket passes on clad tubesheet weld together, stop sleeve is loaded on the inwall of polytetrafluoroethylene (PTFE) pipe end, the polytetrafluoroethylene (PTFE) pipe end that stop sleeve is housed passes tight socket, between tight socket inwall and polytetrafluoroethylene (PTFE) pipe end outer wall, form an annular space, sealing gasket is equipped with in the annular space bottom, and sealing gasket is fixed with housing screw.
In scheme of the present utility model, because polyfluortetraethylene pipe is softer, first at pipe end, install stop sleeve additional, while preventing from sealing, produce irregular deformation, affect sealing effectiveness.Next polyfluortetraethylene pipe is penetrated in tight socket, and the sealing gasket of packing into from the end of polyfluortetraethylene pipe, finally load onto housing screw, rotatably compress screw crush seal pad, make it produce distortion, reach sealing effectiveness.Due to the thermal coefficient of expansion of polytetrafluoroethylene (PTFE) much larger than carbon steel material, so during the hot work of air preheater, the swell increment of polyfluortetraethylene pipe will be much larger than carbon steel, while adopting the direct welded structure of tube and tube plate, because thermal stress can't discharge, and the sealing of fragile tube and tube plate.And in scheme of the present utility model, the polytetrafluoroethylene (PTFE) pipe end can free wxpansion vertically in the passage that tight socket and housing screw inner chamber form, not only sealing is good, and can not damage hermetically-sealed construction, and this just can guarantee reliable sealing property between the tube and tube plate.
