Detailed description of the invention
be further elaborated the present invention below in conjunction with accompanying drawing, wherein, direction of the present invention take Fig. 1 as standard.
referring to figs. 1 through Fig. 2, chemical plant rectification cell operation shell-and-tube heat exchanger embodiment of the present invention is described further.
a kind of chemical plant rectification cell operation shell-and-tube heat exchanger, comprise housing 1, two heat-exchange tubes 2, every root root heat-exchange tube 2 has two respectively, and heat exchange is carried out in the position in the middle of heat-exchange tube 2 in housing 1.Two heat-exchange tubes 2 are respectively a normal temperature pipe, and another root is cooling tube, and cooling tube is connected with air compressor machine, are cooled normal temperature pipe by the compression of compressor, make normal temperature pipe be cooled to below 40 degrees below zero in heat exchanger.In housing 1, two heat-exchange tubes 2 are woven, and carry out heat exchange fully,
wherein, the bottom of described housing 1 is provided with base 6, described base 6 is welded by hollow steel pipe, the hollow steel pipe inside of described base forms a cavity structure communicated, the side of this cavity structure is provided with inlet, the other end is provided with liquid outlet, and the inner surface of described hollow pipe is provided with silane reinforcing magnesium alloy coating.
this chemical plant rectification cell operation shell-and-tube heat exchanger also includes a skeleton 3, and skeleton 3 is stamped to form by a block plate, and form two relative side plates and a top board, side plate and top board are mutually vertical.Housing 1 is positioned at skeleton 3, fills the thermal insulation layer 4 being provided with and being made up of PU blowing agent in skeleton 3, and skeleton 3 outside is provided with the cushion 5 be made up of high-density sponge.This structure improve the simple package structure of original use asbestos, PU blowing agent is compared and common package structure, in the process of foaming, can cover all complete for whole housing 1, omnibearing parcel, completely isolated housing 1 and the contact of outside air, solve asbestos and wrap up the shortcoming that can not intercept completely, progressive comparatively remarkable.The effect of skeleton 3 is the restrictions for blowing agent being done a local, prevents the irregular movement of blowing agent when foaming, causes the distortion of global shape.And at the cushion 5 that parcel one deck is made up of high-density sponge outside skeleton 3, be to ensure the stable of inner expanded material, and play certain effect of heat insulation.Because PU expanded material contacts with housing 1 completely, both are almost integral like this, although the heat-conducting effect of expanded material is poor, if but allow blowing agent directly contact with air, extraneous heat also cries and easily enters housing 1 by expanded material and exist, and therefore needs to superscribe one deck cushion 5 again outside skeleton 3.High-density sponge be compared to Midst density sponge, low-density sponge hardness also high; and can absorb extraneous vibrations, the expanded material that protection is inner frangible, and high-density sponge also comparatively has a thermal insulation; keep the operating temperature of whole heat exchanger, prevent the impact being subject to environment temperature.
and there is no the reserved lower expansion space of blowing agent when solidifying that the omnibearing parcel of skeleton 3 can be larger, if arrange the side plate of four direction, just easily occur that blowing agent is excessive to inner shell 1 squeeze pressure when solidifying.Whole skeleton 3 can allow top board and two pieces jointly form a rectangular shape, and the structure of skeleton 3 determines the structure of this heat exchanger substantially, and it is comparatively compact that cuboid can be installed on mounting structure, and what it is such that entirety can be maximum utilizes the device space.
side plate is provided with for fixing installing plate 31, and installing plate 31 is provided with screwed hole 32.Side plate has installing plate 31 whole chemical plant rectification cell operation shell-and-tube heat exchanger can be allowed to be arranged on equipment, the structure of screwed hole 32 very general on fixed structure, screwed hole 32 can be fixed it with bolt.
the outer wall of described housing is provided with ladder.
heat exchange solution is filled with in described cavity structure.
described heat exchange solution is lithium-bromide solution.
more than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description is only preference of the present invention; be not used for limiting the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
