Detailed description of the invention
In order to make those skilled in the art understand technical scheme of the present invention better, below in conjunction with accompanying drawing and most preferred embodiment, the present invention is described in further detail.
As shown in the figure, the present invention is primarily of plate type heat exchanger 1, frequency conversion moisturizing water pump 2, circulating pump 3, electric control valve 4, ball valve 5, frequency conversion collector 13, controller 6 and switch board (not shown) are formed, described plate type heat exchanger enters, answer back and be connected with a heat supply pipeline 7 and primary water pipeline 7-1 respectively, electric control valve 4 is provided with between a heat supply pipeline and plate type heat exchanger import, plate type heat exchanger delivery port and water return outlet are connected with secondary heat supply pipeline 8 and secondary returning waterpipe 8-1 respectively, described controller is connected with outdoor temperature sensor 9 and temperature sensor 10 and pressure sensor 11, described temperature sensor and pressure sensor are connected with a heat supply pipeline and secondary heat supply pipeline respectively.The bypass of described secondary returning waterpipe is provided with frequency conversion moisturizing water pump 2 and replenishing water tank of water 12.Be provided with liquid level sensor 15 in described replenishing water tank of water, liquid level information is passed to remote terminal by remote protocol by described liquid level sensor.Rely on remote protocol liquid level information to be passed to remote terminal, the Real-Time Monitoring of water supply tank liquid level by liquid level sensor, prevent sky regimen condition from occurring.A described heat supply, water return pipeline and secondary heat supply, water return pipeline are respectively equipped with ball valve 5.Described frequency conversion collector acquisition controller energy data, energy data described in this example is, voltage, electric current, meritorious efficiency, idle efficiency and momentary efficiency, and be passed to remote terminal 14 by remote protocol, described remote terminal accepts energy data, and send control signal and be passed to frequency conversion collector by remote protocol, make frequency conversion collector control controller action.
Operation principle:
Make remote terminal control controller action by frequency conversion collector by remote protocol, thus reach the Long-distance Control to whole central heating monitoring station.
System and control cabinet connects, and has interlock protection and warning function to the overtemperature of heat network system, superpressure, decompression.
O-volt protection: when secondary side pressure of return water is lower than lower bound setting value, moisturizing frequency converter wakes up, and automatic water replenishing system puts into operation, starts moisturizing.After automatic water replenishing system puts into operation secondary side pressure of return water still continue reduce then send warning.
Overtemperature prote: when secondary side supply water temperature exceedes setting value, and when primary side return water temperature exceedes setting value, close primary side electric control valve.
Overpressure protection: it is out of service and close primary side electric control valve that secondary side water main pressure exceedes setting value circulating pump.
System has power-failure protecting, incoming call from the function opened.
Temperature controls, and field controller controls primary side electric control valve according to the supply and return water riser of outdoor temperature sensor, secondary side return water temperature or secondary side, automatically regulates the flow of a secondary net heating agent, and " amount " that realize a secondary net regulates.Thus control the supply water temperature of secondary network further, make its pattern according to setting or curve motion, " matter " that realizes secondary network regulates, and decreases the waste of heat.
Stress control, according to the pressure of supply water of secondary side setting or for backwater pressure reduction, by the running frequency of Frequency Converter Control water circulating pump.According to the supplementing water pressure of setting, by the running frequency of Frequency Converter Control small pump, save the loss of electric energy to greatest extent.When system pressure exceedes setting pressure, magnetic valve is opened and is sluiced.
Realize the distribution according to need of hot net water dynamic balance and heat, ensure that near-end user indoor temperature is too high and cause heat waste, remote subscriber is not complained, namely " comfortable, energy-conservation " principle.
Configure the welding ball valve failure rate is low of the circulating pump of Grandfos brand and small pump, Finland naval in systems in which, and 10 years non-maintaining; All on-site transfer instrument all adopt import to ensure the accuracy of transformation parameter, effectively decrease the maintenance work in later stage.
The thermal efficiency is high, selectes different heat exchanger templates, ensure high heat transfer coefficient, improve heat exchange efficiency according to different parameters.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
