Abstract

The utility model relates to a coil type steam-liquid heat exchanger. In the technical scheme, coil groups which consist of a plurality of spiral coils are arranged in a horizontal cantilever type from top to bottom in the center of a shell of the heat exchanger, a condensate pipe vertically penetrates through each coil group, one side of the coil groups is vertically provided with a steam header; the inlet ends of the coil groups are communicated with the steam header through a conduit, the outlet ends of the coil groups are communicated with the condensate pipe through another conduit, the top of the coil type steam-liquid heat exchanger is provided with a top seal cover of a hot liquid outlet, the bottom of the coil type steam-liquid heat exchanger is provided with a bottom seal cover of a cold liquid inlet, and the coil groups are in threaded connection with the steam header and the condensate pipe. When the utility model operates, the condensate with residual heat can continuously perform the secondary heat exchange with the cold liquid outside the coils when being discharged downwards, thereby greatly improving the heat exchange efficiency. The utility model has the advantages of small size, small occupied space, simple structure, good automatic descaling effect and convenient disassembly, assembly and maintenance.

Description

Coiled pipe type vapour-liquid heat exchanger

Technical field

The utility model is a kind of heat exchanger that carries out hot and cold exchange, especially a kind of coiled pipe type vapour-liquid heat exchanger, it is widely used in heating, air-conditioning and the hot water supply system of industry such as luxurious hotel, restaurant, factory, school, army, hospital and chemical industry, oil refining, shipbuilding and civil buildings.

Background technology

Existing vapor-water heat exchanger is traditional shell-and-tube heat exchanger, and this heat exchanger mainly is made up of parts such as bobbin carriage, tube sheet, cylindrical shell, U type heat pipes, by the cyclic water tank at top as the Inlet and outlet water heating cabinet.After this heat exchanger service time was long, the binding site of tube sheet and U type pipe easily became flexible, and leak source increases.The general cold fluid of this structure flows in pipe, easily causes fouling, increases energy consumption, because U type pipe is folded mutually layer by layer, and interior pipe is changed time-consuming, have to adopt the plug shutoff, like this, heat exchange area reduces, and has reduced heating-up temperature, can not satisfy need of work again.

Summary of the invention

Technical problem to be solved in the utility model: be to provide a kind of energy consumption low, the coiled pipe type vapour-liquid heat exchanger that heat exchange efficiency is high.

For solving the technical scheme that above technical problem adopts is such: the utility model has a barrel-type housing, in housing central authorities, from top to bottom is evenly equipped with the horizontal boom formula coil pipe group of being made up of a plurality of spiral coils that is provided with is installed; And by condensate pipe vertically in each coil pipe group, a side of coil pipe group vertically is provided with the female pipe of steam; The entrance point of coil pipe group is connected through the female pipe of conduit and steam, and its port of export is connected with condensate pipe through another conduit.

Because adopt above technical scheme, its effect is conspicuous:

1, weight of equipment is light, and volume is little, takes up an area of to lack, and transportation and mounting cost are saved in easily carrying.

2, heat exchange efficiency height, its cold water area is little, thermal capacitance is long-pending can be reached about 95% and effectively store, and has improved the capacity utilization of heat exchanger greatly.

3, simple in structure, long service life, automatic desludging is effective.

4, dismounting and maintenance are convenient.

The specific embodiment

With reference to Fig. 1, Fig. 2, the utility model is a kind of coiled pipe type vapour-liquid heat exchanger, this heat exchanger has a barrel-type housing 4, in housing central authorities, the coil pipe group of forming by a plurality of spiral coils 3 that is evenly equipped with from top to bottom that the horizontal boom formula install to be provided with, and by condensate pipe 2 vertically in each coil pipe group, a side of coil pipe group vertically is provided with the female pipe 1 of steam; The entrance point of coil pipe group is connected through the female pipe of conduit 9 and steam, and its port of export is connected with condensate pipe through another conduit 9.When making, in the upper end of housing 4 top closure 5 is set, the lower end is provided with bottom cover 7; Top closure is provided with hydrothermal solution outlet 6, and bottom cover is provided with cold liquid import 8.In addition, the connecting portion of the female pipe 1 of coil pipe group 3 and steam, condensate pipe 2 all is provided with threaded connector.The wall thickness of coil pipe is made as 0.8～1.2mm, because wall is thin, the effect that causes automatic detergency of expanding with heat and contract with cold is very good.

During the utility model operation, steam upwards enters in the female pipe 1 of steam along arrow among the figure, enters respectively and the coil pipe group 3 that connects by each conduit 9, and condenses and release heat in coil pipe, and the cold liquid outer with coil pipe carries out the heat exchange first time.Next, condensate water in the coil pipe enters condensate pipe 2 by another conduit, still in the process that the condensed water that has waste heat direction of arrow in the figure is discharged downwards, constantly proceed heat exchange for the second time on the way with housing inner coil pipe cold liquid outward, so greatly improved the heat exchange efficiency of entire equipment, saved the energy.On the other hand, cold liquid direction of arrow in the figure circulates, enter in the housing 4 from the cold liquid import 8 that is fixed on the bottom cover 7, from bottom to top constantly with mother's pipe, coil pipe, condenser pipe in steam and have twice heat exchange of condensed water of waste heat, liquid after being heated direction of arrow in the figure flows out from the hydrothermal solution outlet 6 that is fixed on the top closure 5, transports to other working equipments.

During the utility model assembling, the coil pipe group of bottommost is 80～110mm apart from housing bottom, so dwindled cold liquid zone, effective storage thermal capacitance is amassed can be reached 95%, has improved the utilization rate of heat exchanger volume greatly.
