The heater provided by the invention has simple structure, reasonable design and flexible application, is convenient to use and can achieve the effects of energy conservation and water conservation, no throttling loss in the regulating process and automatic temperature control and can satisfy the adjustment requirements of heat and power loads.
Description
(1) technical field
The invention belongs to heat supply unit application, particularly a kind of intelligent heat exchangers for district heating that reclaims restriction loss and the spent hot water of power plant.
(2) background technology
Fast development along with urban construction; The applied more and more of extraction for heat supply unit, at present, unit adopts the mode that installs control valve in the extraction for heat supply pipeline additional to satisfy thermic load more; But the pressure of control valve is regulated and can be produced restriction loss; Cause the decline of economy of power plant property, there is high-quality hot water row trench in power plant simultaneously, and waste is unfortunately tangible.
(3) summary of the invention
The present invention provides a kind of simple in structure, easy to operate recovery restriction loss and the spent hot water's of power plant intelligent heat exchangers for district heating in order to remedy the deficiency of prior art.
The present invention realizes through following technical scheme:
A kind of intelligent heat exchangers for district heating that reclaims restriction loss and the spent hot water of power plant; Comprise the heat exchangers for district heating that connects the extraction for heat supply pipeline; On the extraction for heat supply pipeline control valve is installed, it is characterized in that: be connected with cold water inlet pipe, hot water out pipe and drain pipe on the said heat exchangers for district heating, hot water out pipe and power plant's used heat cross current also are equipped with temperature controller on both mixing ducts; Be provided with the connection pipeline of installation and control valve between cold water inlet pipe and the hot water out pipe, control valve is connected with temperature controller.
When the present invention normally moves; The throttling regulating action of cancellation extraction for heat supply pipeline adjusted valve makes it to be in normally open, and the heat supply network backwater is after heating through drawing gas; Earlier mix intensification to trench waste water, sewer etc. with power plant is unrestrained; Utilize the spent hot water of power plant as the heat supply network circulating cooling make-up water,, utilize temperature controller restriction heat exchangers for district heating leaving water temperature then through being installed in the temperature controller on the outlet pipe; Thereby the water yield of regulating heat exchangers for district heating through control valve changes the heat supply amount of drawing gas, and has reached rational heat supply coolant-temperature gage of control and the purpose that reclaims restriction loss.
When the unit electric load changed, extraction for heat supply pressure can change, and temperature controller and control valve can adjust coolant-temperature gage automatically, satisfy hot customer requirements, did not influence the charged load of heat supply unit, increased the automaticity of regulating.
The present invention is simple in structure, and is easy to use, reasonable in design, applying flexible; Energy-saving and water-saving does not have restriction loss in the adjustment process, power plant effluent used heat capable of using can be temperature automatically controlled; Satisfy heat, electric load adjustment requirement, improve the economical effect of heat-supply of heat supply unit, be suitable for wide popularization and application.
(4) description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Fig. 1 is a structural representation of the present invention.
Among the figure, 1 extraction for heat supply pipeline, 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, 9 power plant's used heat water pipes.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.This embodiment comprises the heat exchangers for district heating 2 that connects extraction for heat supply pipeline 1; Control valve 3 is installed on the extraction for heat supply pipeline 1; Be connected with cold water inlet pipe 7, hot water out pipe 8 and drain pipe 5 on the said heat exchangers for district heating 2; Hot water out pipe 8 is communicated with power plant used heat water pipe 9 and temperature controller 6 is installed on both mixing ducts, is provided with the connection pipeline of installation and control valve 4 between cold water inlet pipe 7 and the hot water out pipe 8, and control valve 4 is connected with temperature controller 6; Said control valve 3 is in full-gear when normal operation.
Extraction for heat supply pipeline 1 adjusted valve 2 is in normally open, prepares against and isolates steam turbine and heat-net-pipeline use when stopping steam supply; Connect the cold water inlet pipe 7 and hot water out pipe 8 that gets into heat exchangers for district heating 2 through control valve 4; Under the situation of not throttling of drawing gas; Drain pipe 5 temperature raise; Can improve economy of power plant property when returning the master of power plant therrmodynamic system, the hot water temperature is high when heating hot water out pipe 8 temperature that also than not throttling, after the water in the hot water out pipe 8 mixes with the spent hot water of boiler blowdown water and therrmodynamic system row trench through temperature-sensing valve 4.
Through receiving aperture, regulate water temperature (like 100 degree) in the temperature range of heat distribution pipe network contract requirement in the hot water out pipe 8 from the water temperature signal control control valve 4 of hot water out pipe 8.Through 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 requirements 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 requirements in the hot water out pipe 8.
