The weather compensation arrangement of using on the present engineering, majority is installed at the thermal source primary side, directly controls the supply water temperature of boiler, perhaps regulates the flow of the primary side of thermal substation, changes thermal substation secondary water-supply temperature.Yet in the practical engineering project, especially big municipal heat supply network project can't realize the Flow-rate adjustment control of thermal substation primary side, in order to realize the purpose of weather compensation, must research and develop the weather compensating cabinet that a kind of secondary side is regulated control.
The utility model content
The utility model is researched and developed a kind of thermal substation weather compensation energy-saving device at heating system.The utility model does not need the thermal substation primary side is done any change, adds bypass line at secondary side, changes the actual heat exchange flow of secondary side, reaches the purpose of secondary water-supply temperature weather compensation.
The beneficial effects of the utility model (1) have realized weather compensation control, and heating according to need has been realized saving of heat; (2) adopt the mode of thermal substation secondary side bypass to change heating load, reduce the once transformation of net, it is convenient to implement; (3) multiple operational factors such as monitoring thermal substation temperature, pressure write down thermal substation ruuning situation automatically, have reduced operations staff's workload.
A kind of thermal substation weather compensation energy-saving device is characterized in that: comprise climate compensation controller 1, outdoor temperature sensor 2, heat exchanger 3, secondary water-supply temperature sensor 6, secondary return water temperature sensor 7, secondary bypass pipe 4, unidirectional electric control valve 5, secondary mixing water temperature sensor 8, secondary mixing water pressure sensor 9, secondary pressure of return water sensor 10 and touch-screen 11;
The secondary water return pipeline be provided with secondary return water temperature sensor 7 and, secondary pressure of return water sensor 10; The secondary water return pipeline divides two-way, and one the road is connected to an end of heat exchanger 3, and another road is connected to an end of secondary bypass pipe 4 by unidirectional electric control valve 5, is provided with secondary water-supply temperature sensor 6 between the other end of heat exchanger 3 and the secondary bypass pipe 4; The other end of the other end of heat exchanger 3 and secondary bypass pipe 4 links to each other, and to be merged into one the tunnel be the secondary mixing water lines, and secondary mixing water temperature sensor 8 is set on the secondary mixing water lines.
Further, heat exchanger 3 primary sides are municipal heating power or district boiler room.
Climate compensation controller is regulated the aperture of unidirectional electric control valve on the secondary bypass pipe, changes the flow that the secondary backwater enters heat exchanger.
Part secondary backwater enters the heat exchanger heat exchange, and all the other secondary backwater are by the secondary bypass pipe, after secondary water-supply after the heat exchange mixes, makes the temperature of secondary mixing water sensor monitoring satisfy the requirement of climate compensation controller inner control algorithm.
Climate compensation controller has been gathered the multiple parameters such as aperture that secondary water-supply temperature, secondary return water temperature, secondary change coolant-temperature gage, secondary mixing water pressure, secondary pressure of return water and the unidirectional electric control valve of bypass pipe in the thermal substation, shows by touch-screen.
The utility model comprises climate compensation controller, touch-screen, outdoor temperature sensor, secondary water-supply temperature sensor, secondary return water temperature sensor, secondary bypass pipe, unidirectional electric control valve, secondary mixing water temperature sensor, secondary mixing water pressure sensor and secondary pressure of return water sensor.
Climate compensation controller is embedded weather compensated curve, the weather compensated curve is formed by the setting value match of 16 pairs of outdoor temperatures and water-mixing temperature, control precision height.
Parameter according to the outdoor temperature sensor monitoring, climate compensation controller calculates the secondary water-supply temperature of expectation, regulates the aperture of motorized adjustment on the secondary bypass pipe, makes a secondary side backwater part enter the heat exchanger heat exchange, a part reaches the supply water temperature of expection by bypass pipe behind overmulling water.The caliber of bypass pipe need calculate according to the resistance of practical engineering project.
The thermal substation primary side is municipal heating power, district boiler room or other heat source ways.In the process of secondary side weather compensation, along with the variation of thermal substation secondary side heat exchange amount, the heat that primary side discharges is respective change also, and the supply and return water temperature of primary side hot water and flow parameter can respective change.Primary side is in passive variable condition.
