Summary of the invention
The purpose of this utility model is to provide a kind of direct-heating type heating heat exchange unit, the whole unit one-time investment and the maintenance cost that are mainly the current existing heating heat exchange unit existence of solution are high, with direct-furnish mode heating system control section arrange unreasonable, the problem of the normal operation of the system that affects.
The technical solution of the utility model is as described below: it is by supplying, backwater control valve, pressure sensor, temperature sensor, direct heater, circulating pump, water supply tank, small pump, filter, safety valve, booster pump, thermometer, Pressure gauge, non-return valve, butterfly valve and water supply line composition, a described secondary net feed pipe and secondary network return pipe directly access direct heater, then send into secondary network feed pipe, on secondary network return pipe, connect respectively small pump and safety valve, between secondary network return pipe and a secondary net return pipe, booster pump is set, and a secondary net is supplied, return pipe and secondary network supply, established temperature sensor on return pipe, pressure sensor output signal is access controller input respectively, and controller output end respectively with confession, backwater control valve, circulating pump, small pump is connected with booster pump.
The beneficial effects of the utility model: this heat exchange unit is owing to having taked said structure, can utilize secondary network feed pipe temperature to control the aperture for water regulating valve on a secondary net feed pipe by temperature sensor, controller, thereby the water supply flow that ensures to enter direct heater, makes direct heater outlet temperature reach design temperature.And by the aperture of pressure sensor institute measuring pressure via controller control one secondary net return pipe backwater control valve on secondary network return pipe, control a secondary net backwater amount.And at the pressure of secondary network return pipe pressure sensor (herein arrange pressurization point) during lower than preset lower limit, small pump, to system water supplement, remains in setting range the pressure of pressurization point.In the time that pressurization point pressure exceedes capping pressure, safety valve is opened pressure release automatically, and guarantee system is moved within the scope of safe pressure.Moreover, this utility model also have inventive concept novelty, design science rationally, the advantage such as operation controls simple, stable and reliable operation, not only economy but also practicality, be applicable to wideling popularize.
Brief description of the drawings
Fig. 1 is direct-heating type heating heat exchange unit structural representation.
Detailed description of the invention
Direct-heating type heating heat exchange unit shown in Fig. 1 is a kind of novel heating heat exchange unit.It is through supplying water regulating valve (electronic control) 1, butterfly valve 2, directly accessing direct heater 4 with the secondary network return pipe being connected through filter 3 by a secondary net feed pipe, then be connected with secondary network feed pipe through circulating pump 5, non-return valve 6, butterfly valve 21,22, between secondary network feed pipe and return pipe, be provided with non-return valve 61, on secondary network return pipe, be provided with the small pump 8 being connected with water supply tank 7 and non-return valve 62, butterfly valve 23,24, on this secondary network return pipe, be also provided with safety valve 11.Backwater control valve (electronic control) 9 booster pumps that are connected 10 that are simultaneously provided with and be connected on non-return valve 63, butterfly valve 25,26 and a secondary net return pipe, are separately connected through another butterfly valve 27 secondary network return pipe with the set backwater control valve 9 of a secondary net return pipe.On a described secondary net feed pipe, return pipe, be respectively equipped with temperature sensor 12,121, pressure sensor 13,131 and thermometer 14,141, Pressure gauge 15,151.On described secondary network feed pipe and return pipe, be also respectively equipped with temperature sensor 122 and 123, pressure sensor 132 and 133, and thermometer 142,143, Pressure gauge 152,153.Meanwhile, this heat exchange unit is also provided with controller 16, described controller 16 is the single-chip microcomputers by computer program control, by a secondary net feed pipe, return pipe and secondary network feed pipe, return pipe established temperature sensor 12,121,122,123 and pressure sensor 13,131,132,133 output signals access controller 16 inputs respectively, and controller 16 output control terminals are connected with booster pump 10 respectively with for, backwater control valve 1,9, circulating pump 5, small pump 8.
When the work of this heat exchange unit, high-temperature-hot-water from a secondary net enters direct heater 4 by confession water regulating valve 1 and butterfly valve 2 from a secondary net feed pipe, with the direct Hybrid Heating of water through in the secondary network return pipe of filter 3, heated water is delivered to user by circulating pump 5, non-return valve 6 and butterfly valve 21,22.Along with entering of high-temperature water, secondary network hydraulic pressure can raise gradually, and unnecessary water is returned to (now a secondary net pressure ratio secondary network pressure is high) in a secondary net return pipe by available booster pump 10, and by butterfly valve 27 equilibrium water flows.In running, the utility model mainly arranges two control points, and one is secondary network supply water temperature; Another is secondary network pressure of return water.Be weighed warm spot and pressurization point.The control of temperature is, by temperature sensor 122, the temperature signal of detection is sent into controller 16, controller 16 is through internal data processing, control signal is directly sent into the adjusting that automatically realizes aperture by it for water regulating valve 1, the temperature that meets secondary network water supply to control a secondary net water supply flow makes it to reach the temperature of setting.And the pressure control of secondary network return pipe is to utilize pressure sensor 133 that pressurization point pressure signal is directly sent into controller 16, controller 16 treated with relatively make following control: when measured pressure point pressure is when setting value, controller 16 is connected booster pump 10 working powers, and the part in the secondary network backwater filtering through filter 3 is returned in the return pipe of a secondary net.While is according to the aperture of pressurization point pressure control backwater control valve 9, thereby the backwater amount of a secondary net is controlled in realization.When the aperture of backwater control valve 9 reaches maximum, the pressure point pressure of measuring during higher than capping value, safety valve 11 is opened pressure release automatically, guarantee system is moved within the scope of safe pressure.And connect small pump 8 working powers lower than preset lower limit Time Controller 16 when institute's pressure point pressure of measuring, small pump 8 fills into the water extraction in water supply tank 7 the normal operation of guaranteeing system in the return pipe of secondary network.In figure, the setting of non-return valve 61 is that the water attack of avoiding circulating pump 5 to produce in the time having a power failure plays a protective role to circulating pump 5.
