Abstract
The utility model relates to a water-water heat exchanger, which comprises a housing, a heat exchange tube group, a tube case, a support bracket, a seal cover, a tube group seal cover, a safety valve, a pressure meter and a thermometer. The utility is characterized in, a baffling shelf is arranged inside the housing, and a diversion baffle is arranged at heat source water inlet and outlet. The inlet and outlet of the heating water are positioned at the upper part and lower part of the two ends for housing separately. The heat exchange way of the utility model is a counter-flow forcing way, which has the advantages of long heat exchange flow, high temperature at the outlet, and high heating efficiency.
Description
Technical field
The utility model is a kind of heat exchanger, and it relates to a kind of water-water heat exchanger.
Background technology
In the prior art, water-water heat exchanger, it comprises shell, U-shaped set of heat exchange tubes, bobbin carriage, support, capping, the capping of pipe group, safety valve and Pressure gauge, assemblies such as thermometer.There is following shortcoming in it: be subjected to be the following current heat exchange mode on hot water entrance's the layout, i.e. import is arranged in heat source water one end of housing, and delivery port is arranged in the other end of housing, is subjected to the leaving water temperature of hot water to carry not high like this; Be subjected to hot water along heating tube group PARALLEL FLOW, with the convection type heat exchange, flow process is short, the thermal efficiency; After heat source water enters bobbin carriage, can not flow into set of heat exchange tubes equably, also influence the utilization of heat energy.
Summary of the invention
The purpose of this utility model just is: overcome the shortcoming of prior art, disclose a kind of leaving water temperature height, long flow path, the technical scheme of the water-water heat exchanger that efficient is high.
Of the present utility modelly be achieved in that a kind of water-water heat exchanger, comprise housing, set of heat exchange tubes, bobbin carriage, the support capping, the capping of pipe group, safety valve and Pressure gauge, thermometer is characterized in that: be provided with the baffling dividing plate in the housing, the porch of heat source water is provided with flow apron; Be subjected to the import and export of hot water to be located at lower part of frame and top respectively.
The feature of above-mentioned heat exchanger also is: the baffling dividing plate is located between the import and export that are subjected to hot water, its quantity can be set according to the needs of flow process, has only a baffling mouth between every shelf and the housing, the baffling mouth can following form setting: from being subjected to the hot water entrance, the baffling mouth of first dividing plate is located at the left end of dividing plate, the baffling mouth of second dividing plate is located at the right-hand member of dividing plate, and is arranged in a crossed manner successively later on; Be subjected to the outlet of hot water to be located at the top by heat source water one end of housing, import is located at the bottom of the other end of housing.The utility model is compared with prior art: because it is provided with the baffling dividing plate, make can only flow by the baffling mouth that is provided with by hot water, so just changed originally only with the convection type heat exchange, be the heat exchange of a kind of pressure mode, increased heat exchange process; Be subjected to the setting of the import and export position of hot water, make it present a kind of countercurrent heat exchange method, the water temperature of delivery port more approaches the temperature of heat source water; The flow apron that the import department of heat source water is provided with can make heat source water be imported set of heat exchange tubes equably.Therefore, it is long to the utlity model has heat exchange process, efficient height, leaving water temperature advantages of higher.This technology once was used for a technological transformation project, obtained good effect.Because original equipment is subjected to the restriction of various objective condition, does not change as boiler in heating system, the heat source water temperature of its outlet is set at 65C.Through former heat exchanger heat exchange, leaving water temperature can only 45C, and water temperature is too low, can not satisfy instructions for use.After adopting technological transformation of the present utility model, supply water temperature has improved 15C, reaches 60C, near the temperature of heat source water, improves and uses water quality, has satisfied instructions for use.

Specific embodiments
Further set forth concrete enforcement of the present utility model below in conjunction with accompanying drawing.
Please refer to Fig. 1, the utility model comprises housing 1, set of heat exchange tubes 2, and Pressure gauge 3, safety valve 4, thermometer 5, bobbin carriage 6, support 7, capping 8, pipe group capping 9 is characterized in that: be provided with baffling dividing plate 10 in the housing 1; 14 places are provided with flow apron 11 in the heat source water import; Baffling dividing plate 10 is located at the import 12 that is subjected to heat source water, between the outlet 13, its quantity can be decided according to the needs of flow process length, have only a baffling mouth 15 baffling mouths to be set to good in the following manner between every dividing plate 10 and the housing 1: from being subjected to hot water inlet 12, the baffling mouth 15 of first dividing plate 10 is located at the left end of dividing plate, the baffling mouth 15 of second dividing plate is located at the right-hand member of dividing plate, and is arranged in a crossed manner successively later on.Be subjected to the outlet 13 of heat source water to be located at the top by heat source water import 14 1 ends of housing 1, import 12 is located at the other end bottom of housing 1; Whole interchanger is supported by two supports on the housing 17; Housing 1 is provided with capping 8, can unload pipe group capping 9 after unloading, with scavenge pipe group inner chamber; Pull down bobbin carriage 6, extract pipe group 2 out, can clean housing 1 inner chamber, cleaning hose group outer wall, and clean bobbin carriage, to improve the heat transfer efficiency and the quality of water supply of (recovery) interchanger.Also be provided with Pressure gauge 3 at housing 1, safety valve 4 and bimetallic thermometer 5 are in order to the pressure and the temperature of monitoring and understanding tube side.
Now working mechanism of the present utility model is summarized as follows: see also Fig. 2, Fig. 3, Fig. 4.As seen from the figure, after flowed into from import 12 by hot water, effect because of baffling shelf 10, water can only be successively baffling mouth 15 by every shelf flow to delivery port 13, so just changed and only depended on the convection type heat exchange originally, be the heat exchange of a kind of pressure mode, both increased the heat exchange chance, also increase heat exchange process, improved heat exchange efficiency.As can be seen from Figure 3 be subjected to the cold of hot water, the hot water entrance is a kind of countercurrent heat exchange method, and the temperature that goes out saliva will improve supply water temperature near the temperature of heat source water.As can be seen from Figure 4, after heat source water enters bobbin carriage,, also improved heat exchange efficiency because the effect of flow apron can import set of heat exchange tubes more uniformly with heat source water.
