Specific embodiment
With reference to embodiments and accompanying drawing the invention will be further described.
Referring to Figures 1 and 2, the present invention includes a water tank 1, the bottom of water tank 1 is equipped with cooling water inlet 16, top is equipped with hot water outlet 14, bottom is equipped with the sewage draining exit 19 discharged water during for overhauling, and the manhole 15 for being easily installed maintenance is equipped with the middle part of water tank 1, and the water tank 1 is also fixedly equipped with the hanger 110 for lifting, to ensure that water tank 1 is steadily erected at ground, water tank 1 goes back pot bottom and is additionally provided with three supporting legs 111.
High-efficiency board type heat transfer device 3 is fixedly equipped with outside the tank body of water tank of the present invention 1, the circulating water outlet 17 that the water inlet 31 of the plate type heat exchanger 3 passes through the bottom of 5 UNICOM's water tank of self-circulation system 1, the circulating water intake 18 that the delivery port 32 of the plate type heat exchanger 3 passes through the top of pipeline UNICOM water tank 1, the hot media import 33 of the plate type heat exchanger 3 is connected with heating agent temperature control system 2.Plate type heat exchanger of the present invention 3 is completely separable with water tank 1, is supported on the tank body of water tank 1 by the angle steel that is welded on tank body, therefore when heat-exchanger rig is overhauled, in tank body water without discharge, to reach the purpose of water saving.
4~Fig. 6 of reference picture, self-circulation system of the present invention 5 includes the ball valve 51 of connection circulating water outlet 17, the other end of ball valve 51 is connected with filter 52, the other end of filter 52 is connected with circulating pump 53, the other end of circulating pump 53 is connected with check-valves 55, the water inlet 31 that the other end of check-valves 55 passes through the connecting plate type heat-exchanger rig 3 of ball valve 54.Circulating pump of the present invention 53 can be such that the water in tank is flowed in tank and in self-circulation system 5, self-circulating water import 18（See Fig. 6）Structure is stretched using interior, even water temperature in water tank 1 is ensure that.
2~Fig. 3 of reference picture, heating agent temperature control system 2 of the present invention includes a hot media inlet pipeline 25, the hot media inlet pipeline 25 is connected with isolating valve, 21, the other end of isolating valve, 21 is connected with y-type filter 22, the other end of the y-type filter 22 is connected with electric control valve 23, the other end of the electric control valve 23 is connected with isolating valve, 24, the other end of the isolating valve, 24 is connected by pipeline with the hot media import 33 of plate type heat exchanger 3, one side reduction of fractions to a common denominator road 28 is also equipped with described hot media inlet pipeline 25, the other end of bypass branch 28 also connects hot media import 33, and it is equipped with isolating valve, 27 in the middle of the bypass branch 28.
