Description
Technical field
The invention belongs to a kind of thermal substation weather compensation energy saver of central heating thermal substation secondary heat supply network.
Background technology
Heating system thermal source (comprising boiler and heat exchange station) is all according to the meteorologic parameter design and establishing of extreme severe cold, do not having in the situation of regulating measure, in the situation that outdoor temperature rises or the solar radiation condition is good, superheating phenomenon just appears in the terminal use, has caused the waste of heat.Weather compensation is to realize a kind of energy saver of heating according to need, regulates supply water temperature according to the variation of outside air temperature, reduces user's heating load, reduces terminal superheating phenomenon, realizes energy-saving and cost-reducing.
The weather compensation device of using on the engineering at present, 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 large 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 regulate the weather compensation cabinet of controlling by a kind of secondary side of research and development.
Summary of the invention
The present invention is directed to heating system and research and develop a kind of thermal substation weather compensation energy saver.The present invention 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 thermal climate compensation.
Beneficial effect of the present invention (1) has been realized weather compensation control, and heating according to need has been realized saving of heat; (2) adopt the mode of thermal power station secondary side bypass to change heating load, reduce the transformation to a secondary net, it is convenient to implement; (3) the multiple operational factors such as monitoring thermal substation temperature, pressure record thermal substation ruuning situation automatically, have reduced operations staff's workload.
A kind of thermal substation weather compensation energy saver is characterized in that: comprise that climate compensation controller mixes water pressure 1, the mixed water pressure 2 of outdoor temperature sensor, the mixed water pressure 3 of heat exchanger, the mixed water pressure 6 of secondary water-supply temperature sensor, the mixed water pressure 7 of secondary returning water temperature sensor, the mixed water pressure 4 of secondary bypass pipe, the mixed water pressure 5 of unidirectional electric control valve, the mixed water pressure 8 of secondary water-mixing temperature sensor, the mixed water pressure 9 of the mixed water pressure sensor of secondary, the mixed water pressure 10 of secondary returning water pressure sensor and the mixed water pressure 11 of touch-screen.
Be provided with on the secondary returning water lines the mixed water pressure 7 of secondary returning water temperature sensor and, the mixed water pressure 10 of secondary returning water pressure sensor; The secondary returning water lines is divided two-way, one the road is connected to an end of the mixed water pressure 3 of heat exchanger, another road is connected to the end that the secondary bypass pipe mixes water pressure 4 by the mixed water pressure 5 of unidirectional electric control valve, is provided with the mixed water pressure 6 of secondary water-supply temperature sensor between the mixed water pressure 4 of the other end of the mixed water pressure 3 of heat exchanger and secondary bypass pipe; The other end of the other end of the mixed water pressure 3 of heat exchanger and the mixed water pressure 4 of secondary bypass pipe links to each other, and to be merged into one the tunnel be the mixed water lines of secondary, on the mixed water lines of secondary secondary water-mixing temperature sensor is set and mixes water pressure 8;
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, so that the temperature of the mixed water sensor monitoring of secondary satisfies the requirement of control algolithm in the climate compensation controller.
Climate compensation controller has gathered the many kinds of parameters such as aperture that secondary water-supply temperature, secondary returning coolant-temperature gage, secondary in the thermal substation change coolant-temperature gage, secondary mixed water pressure, secondary returning water pressure and the unidirectional electric control valve of bypass pipe, shows by touch-screen.
The present invention includes climate compensation controller, touch-screen, outdoor temperature sensor, secondary water-supply temperature sensor, secondary returning water temperature sensor, secondary bypass pipe, unidirectional electric control valve, secondary water-mixing temperature sensor, the mixed water pressure sensor of secondary and secondary returning water pressure sensor.
Climate compensation controller is embedded weather compensation curve, the weather compensation curve is formed by the setting value match of 16 pairs of outdoor temperatures and water-mixing temperature, and the control precision is high.
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 to 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 power station 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.
