Description

The tubular type steam-water heat exchanger that a kind of heating, hot-water supply system are used

The utility model is used for heating, hot-water supply system, relates to the steam-water heat exchanger in this system.

Be widely used in heating, the hot-water supply system in various places such as hotel, office, school, hospital, factory and dormitory, generally be with steam cold water to be heated to uniform temperature, realizes heating, heat supply water by a hot water circulating pipeline.One of critical component wherein is steam-water heat exchanger or claims steam water heater.Commonly used at present is a kind of floating coiled pipe steam-water heat exchanger (producing as the Pingdu North Sea, Qingdao City boiler accessory machinery factory), and it is by end cap, cylindrical shell, steam feeding tube, condensate water delivery line and horizontal floating coiled pipe are formed up and down.Cold water imports cylindrical shell by the water inlet pipe that is located on the bottom end cover, steam enters floating coiled pipe in parallel by steam feeding tube, and in coil pipe condensation heat, cold water is heated from bottom to top, hot water is flowed out by the outlet pipe that is located on the upper end cover, is flowed out by the condensate water delivery line after steam condenses in coil pipe.The defective of this heat exchanger is: (1) rate of heat exchange is low, has a large amount of heats not absorbed by cold water in the steam condensate; (2) waste water, steam condensate is banished by meaningless; (3) the hot water supply is little, and steam consumption is big; (4) bulky, heavy, the production cost height.

The QSH steam-water pipe hybrid heater that the smart tool of Anhua, Hunan HVAC Manufacturing Co., Ltd provides is made up of three-way body, jet pipe, screen pack, blowdown plug, sealing gasket.It directly is connected in pipe-line system, be heated liquid flow at high speed in jet pipe, the little inclined hole of steam from the jet pipe outer side surface is pressed into being heated the liquid in the jet pipe at a high speed, formation is to netted continuous, the high speed tiny jet of central shaft to assembly, both are realized in the flow at high speed good the mixing in jet pipe, thereby realized steam and the full heat exchange that is heated liquid, improved the thermal efficiency.The subject matter that this heater exists is to produce tedious roar and vibration, forms noisy environment and pollutes, and has influenced the service life of heating, hot-water supply system and building, influences the live and work of resident family and surrounding resident.

The utility model is in order to overcome the shortcoming with upper heater, the spy provide a kind of simple in structure, volume is little, cost is low, full heat exchange, thermal efficiency height, hot water is in large supply, steam consumption is few, noiselessness and vibrationless steam water heater.

In order to achieve the above object, the utility model adopts the tubular type three-way body, design has some steam pipes in housing, there is fixed disk at two ends, the steam pipe left and right sides, design has the through hole of fixed steam pipe on the fixed disk, steam pipe and left and right sides fixed disk combine as a whole by this hole, and fixed disk is fixed on the inner walls.Form a condensation storehouse between left and right sides fixed disk and the housing, the condensation storehouse communicates with cooling water inlet (circulating water intake) on the housing, form a steam storehouse between right-hand member fixed disk and the housing, the steam storehouse communicates with steam inlet on the housing, form the carbonated drink mixing bunker between left end fixed disk and the housing, this mixing bunker communicates with hot water outlet on the housing.Also design the through hole that has the condensation storehouse to communicate on the fixed disk of a left side with mixing bunker.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a front view of the present utility model.

Fig. 2 is an A-A cutaway view of the present utility model.

Fig. 3 is a B-B cutaway view of the present utility model.

Fig. 4 is that the utility model is installed in the position view in the heating system.

As shown in Figure 1, the utility model is made up of housing 10, steam pipe 5, fixed disk (3,7), cooling water inlet 12, steam inlet 13, hot water outlet 11, sewage draining exit 8.Housing 10 is made by seamless steel pipe, its left end design has hot water outlet 11, and its right-hand member design has steam inlet 13, and design has the steam pipe parallel with its axis 5 in the housing 10, steam pipe 5 usefulness copper tubes are made, steam pipe two ends, 5 left and right sides and middle part are evenly distributed with 2～5 fixed disks (3,7), and design has the through hole of fixed steam pipe on each fixed disk, steam pipe 5 is by these holes and each fixed disk (3,7) combine as a whole, each fixed disk (3,7) is fixed on housing 10 inwalls.Form a condensation storehouse 6 between fixed disk (3,7) and the housing 10, design has cooling water inlet (circulating water intake) 12 on the housing 10 at 6 positions, condensation storehouse.Form a steam storehouse 4 between right-hand member fixed disk 3 and the housing 10, steam storehouse 4 communicates with steam inlet 13 on the housing 10.Form carbonated drink mixing bunker 1 between left end fixed disk 7 and the housing 10, carbonated drink mixing bunker 1 communicates with hot water outlet 11 on the housing 10, and designing on mixing bunker 1 has radiator valve thermistor interface 2.As shown in Figure 1 and Figure 2,1～4 fixed disk 7 on right-hand member fixed disk 3 left sides has all been opened the through hole 9 that communicates with mixing bunker 1, and all design has sewage draining exit 8 on steam storehouse 4 and mixing bunker 1.As Fig. 1, shown in Figure 3, when right-hand member fixed disk 3 plays 5 effects of fixed steam pipe, steam storehouse 4 and condensation storehouse 6 are isolated, steam pipe 5 communicates with steam storehouse 4.As shown in Figure 4, installation principle and the effect of the utility model in heating system.

The utility model has following preferential treatment point with existing steam water heater ratio: (1) steam with In the cold water heat exchanging process, both adopted steam indirect cold water, cool water heating had been arrived certain After the temperature, steam condensate (SC) again water direct and after the heating mixes, and further improves water temperature, makes The heat of steam condensate (SC) is fully used, and steam condensate (SC) is participated in whole heat directly simultaneously Heat energy and water consumption have been saved in the circulation of water circulation system. By every 10000m²House heating needs Calculate, but consumed water 10～12T/ days than the heat exchanger adopting floating coil pipe steam saving, only this One, can cut down expenses 18～270,000 yuan every year; (2) with the house of area, the equipment investment ratio Heat exchanger adopting floating coil pipe reduces 50%; (3) volume is little, in light weight, only is floating coiled pipe heat 1/4～1/3 of interchanger; (4) rate of heat exchange reaches 100%; (5) because adopt the steam indirect After, condensed water directly mixes with heating water again, has dwindled both temperature difference, has eliminated whole adopting Noise and the vibration of warm, heating system.
