Description
(1) technical field:
The steam-operating heat exchange unit that the present invention relates to a kind of shell-and-tube heat exchanger and use the aforementioned tube shell heat exchanger belongs to the heat-exchange apparatus technical field.
(2) background technology:
Existing shell-and-tube heat exchanger is formed by tube side and shell side two parts of sealing alone, tube side fluid and shell-side fluid are the main exchange heat of carrying out with the heat exchange pattern by the heat exchange tube wall in the process of individual flow separately, because the thermal conductivity factor of the fluid film of close heat exchange tube wall is extremely low, greatly hamper the transmission of heat, so the heat exchange efficiency of conventional tube shell heat exchanger is not high.Though on this basis, people are with heat exchanger tube or be processed into helical form, node shape, or the heat exchange tube wall processed band, screw thread or the like, changed the flow condition of fluid, improved heat exchange efficiency to a great extent, be widely used now, but above-mentioned all changes fundamentally do not solve the problem of thermal resistance, so the heat exchange effect is unsatisfactory, particularly in the steam-water heat exchanging process, what heat exchange mainly utilized is the latent heat of vaporization of steam, when a large amount of heat energy is wasted, has also wasted the kinetic energy that a large amount of condensed waters and band are pressed steam.With this type of heat exchanger is that the heat exchange unit that core is formed needs the forced circulation of water pump could supply with hot user's use, a large amount of electric energy of consumption that needs in service.
And the direct vibrations and the noise that are produced of mixing of existing carbonated drink directly mixing type heat exchanger carbonated drink is excessive, because these two disadvantages are difficult to solution, so also be difficult to practical application at present.The heat exchange unit of being formed with this type of heat exchanger not only is directed at problems such as the operation noise is big, fault rate is high, the life-span is short for above-mentioned reasons, also be subjected to the influence of steam pressure and cause moving extremely unreliable, so also be difficult to practical application at present.
(3) summary of the invention:
The present invention is directed to above-mentioned the deficiencies in the prior art, provide that a kind of stable performance, safe, the thermal efficiency can reach 100%, Remarkable Energy Saving novel pipe shell type steam-operating heat exchanger.
Another object of the present invention is to provide more than one to state the steam-operating heat exchange unit that shell-and-tube steam-operating heat exchanger is a core, this heat exchange unit under normal circumstances need not the water circulating pump forced circulation, operating cost is low, save essential water supply tank of traditional heat exchange unit and small pump, reduced manufacturing cost and operating cost.
The present invention finishes by following technical measures:
Shell-and-tube steam-operating heat exchanger of the present invention, include housing, bobbin carriage, front tube sheet, back tube sheet, tube bank and hybrid chamber end socket, tube bank is fixed between front tube sheet and the back tube sheet, the front end of housing is provided with a refrigerant import, the center that the front end of bobbin carriage is provided with a heating agent import, hybrid chamber end socket is provided with mixing matchmaker outlet, its special feature is: be fixed with a conic jet device on the described back tube sheet, the bottom of injector be positioned at tube bank outlet around, the top of injector exports relative with the mixing matchmaker and leaves the gap; Be positioned on the outer back tube sheet of injector bottom circumference and have some apertures, form hybrid chamber between injector and the hybrid chamber end socket.
Above-mentioned shell-and-tube steam-operating heat exchanger, in order to prevent the injector vibrations, the described injector outside is fixed with a dynamic mount.
A kind of steam-operating heat exchange unit that comprises aforementioned tube shell-type steam-operating heat exchanger, its annexation is: be connected with the end user between the mixing matchmaker outlet of shell-and-tube steam-operating heat exchanger and the refrigerant import, and, mix between matchmaker's outlet and the end user also being parallel with a spare circulating pump by pipeline formation main circulation loop.
Above-mentioned steam-operating heat exchanger for whole unit is controlled automatically, is connected with magnetic valve, temperature sensor, teletransmission Pressure gauge, electro connecting pressure gauge, and is controlled by electric cabinet on main circulation loop.
Shell-and-tube steam-operating heat exchanger of the present invention, shell-and-tube heat exchanger and injector closely are connected as a single entity, and shell-and-tube heat exchanger heat exchange principle combined with the injector jet current principle be applied in the heat exchanging process, not only realized the zero thermal resistance exchange heat between heating agent and refrigerant, and can make full use of the sensible heat value of condensed water, make the thermal efficiency reach 100%, can also make full use of band and press the kinetic energy of steam, the realization system does not have the pump circulation, further realize purpose of energy saving, and the system that can be saves water supply tank and small pump, and energy-saving effect is extremely remarkable.Owing to improved the thermal efficiency, make its volume descend about 2/3 than the shell-and-tube heat exchanger of same model, not only save material, and reduced floor space.
This heat exchanger has avoided carbonated drink directly to mix in heat transfer process, has really realized noiseless, shockproof operation, and is safe and reliable to operation, and the service life of greatly having improved heat exchanger.
This heat exchange unit need not the water circulating pump forced circulation under the normal situation of steam pressure, rely on band to press the power of steam can realize not having the pump circulation.Be lower than moving system at steam pressure and circulate under the situation of required pressure, also can start standby water circulating pump and make auxiliary circulation, the system that both guaranteed is safe and reliable to operation, has saved operating cost again to greatest extent.This heat exchange unit has made full use of steam condensate (SC) and has carried out moisturizing, has saved essential water supply tank of traditional heat exchange unit and small pump, has not only reduced manufacturing cost, has also reduced operating cost simultaneously.
