The device of transformation of the straight condensing unit into the heat supply unit for improving the heat supply economical effect comprises a heating network heater, and the device is characterized in that a heat supply bleeding pipeline which is connected with the heating network heater is provided with a regulating valve; the heating network heater is provided with a cold water inlet pipe and a hot water outlet pipe; the hot water outlet pipe is provided with a temperature controller; a control valve is connected with the cold water inlet pipe and the hot water outlet pipe; and the temperature controller is connected with the control valve. The device provided by the invention has a simple structure, is convenient to use, is reasonable in design, is flexible in applications, has no throttle loss, and can control temperature automatically and regulate heat load automatically, within the design range, the power load regulation is not influenced, and the device is suitable for popularization and applications widely.
Description
(1) technical field
The invention belongs to heat supply unit application, particularly a kind of pure condensate changes the device that the heat supply unit improves economical effect of heat-supply.
(2) background technology
Fast development along with urban construction, the pure condensate unit gets more and more at the unit that intermediate pressure cylinder draws gas for heating to the punching of low pressure (LP) cylinder cross over pipe, the most heating of unit are at present drawn gas by the external heat supply of the mode that installs control valve additional, satisfying hot user's heat supply requirement, but throttling process produces loss, causes economy of power plant decline, system can not realize the heat supply temperature adjustment automatically along with climate change, cause the waste of the energy, be subjected to the restriction of electricity determining by heat simultaneously, can not satisfy the service requirement of electrical network.
(3) summary of the invention
The present invention provides a kind of pure condensate simple in structure, no restriction loss to change the device that the heat supply unit improves economical effect of heat-supply in order to remedy the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of pure condensate changes the device that the heat supply unit improves economical effect of heat-supply, comprise heat exchangers for district heating, it is characterized in that: the heat supply pump-line that connects heat exchangers for district heating is provided with control valve, heat exchangers for district heating is provided with cold water inlet pipe, hot water out pipe and drain pipe, temperature controller is installed on the hot water out pipe, control valve connects cold water inlet pipe and hot water out pipe, and temperature controller is connected with control valve.
The control valve of the present invention on pump-line is in normally open, and the throttling action of cancellation control valve is prepared against and isolated steam turbine and heat-net-pipeline use when stopping steam supply; And thermostat is installed on hot-water line, by being connected of thermostat and control valve, according to the leaving water temperature of heat exchangers for district heating automatically control flow through the water yield of heat exchangers for district heating, thereby change the amount of drawing gas, the heat supply network leaving water temperature can artificially be controlled.
The present invention is simple in structure, and is easy to use, reasonable in design, applying flexible, and no restriction loss can be temperature automatically controlled, regulates thermic load automatically, in scope of design, do not influence electric load and regulate, and is suitable for wide popularization and application.
(4) description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present invention.
Among the figure, 1 heat supply pump-line, 2 heat exchangers for district heatings, 3 control valves, 4 control valves, 5 drain pipes, 6 temperature controllers, 7 cold water inlet pipes, 8 hot water out pipe.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises heat exchangers for district heating 2, the heat supply pump-line 1 that connects heat exchangers for district heating 2 is provided with control valve 3, heat exchangers for district heating 2 is provided with cold water inlet pipe 7, hot water out pipe 8 and drain pipe 5, temperature controller 6 is installed on the hot water out pipe 8, control valve 4 connects cold water inlet pipe 7 and hot water out pipe 8, and temperature controller 6 is connected with control valve 4.
Heat supply pump-line 1 adjusted valve 2 is in normally open, prepares against and isolates steam turbine and heat-net-pipeline use when stopping steam supply.Connect cold water inlet pipe 7 and the hot water out pipe 8 that enters heat exchangers for district heating 2 by control valve 4.Under the situation of not throttling of drawing gas, drain pipe 5 temperature raise, and can improve economy of power plant when returning the master of power plant therrmodynamic system.By receiving aperture, regulate water temperature (as 80 degree) in the temperature range of heat distribution pipe network contract requirement in the hot-water line from the water temperature signal control control valve 4 of hot water out pipe 8.By this adjusting, when weather was colder, the temperature of cold water inlet pipe 7 was lower, and heat exchangers for district heating 2 thermal balances strengthen throttle flow automatically, the heating hot net water, and temperature controller 6 sends the aperture that signal reduces control valve 4, satisfies water temperature requirement in the hot water out pipe 8.When weather was warmmer, the temperature of cold water inlet pipe 7 was higher, and heat exchangers for district heating 2 thermal balances reduce throttle flow automatically, the heating hot net water, and temperature controller 6 sends the aperture that signal strengthens control valve 4, satisfies water temperature requirement in the hot water out pipe 8.
Claims (2)
1. a pure condensate changes the device that the heat supply unit improves economical effect of heat-supply, comprise heat exchangers for district heating (2), it is characterized in that: the heat supply pump-line (1) that connects heat exchangers for district heating (2) is provided with control valve (3), heat exchangers for district heating (2) is provided with cold water inlet pipe (7), hot water out pipe (8) and drain pipe (5), temperature controller (6) is installed on the hot water out pipe (8), control valve (4) connects cold water inlet pipe (7) and hot water out pipe (8), and temperature controller (6) is connected with control valve (4).
