Background technique
Present heat-engine plant circulating water cooling system returns electric generator inner cooling but loop and recycle after through the water tower cooling of drying in the air; Most of residue heat energy is dispersed in the atmosphere through the water tower that dries in the air; The heat-exchanger rig that on cooling circuit, does not connect civilian heat exchange exchanger and warm water cultivation mostly; Need the very big water tower that dries in the air of investment construction volume or heat diffusion area, lack the residual heat recovery system that has the intelligent temperature control device, cause certain energy waste and cost of electricity-generating too high.
Summary of the invention
The present invention is directed to the deficiency of existing technology; A kind of reasonable in design, simple and reliable heat-engine plant circulating water reuse cooling system is provided; When effectively reducing secondary reuse circulating water temperature; Excavate the economic value that residual heat of electric power plant utilizes, have reasonable in design, simple in structure, reliable advantage.
The objective of the invention is to realize: a kind of heat-engine plant circulating water reuse cooling system through following technological scheme; But loop, coolant outlet hose, reflow pipe, user's heat exchanger, solenoid valve A, solenoid valve B, the water tower that dries in the air, breed pond heat exchanger, superconducting heat pipe, temperature transducer and temperature detect switch (TDS) are formed by electric generator inner cooling; Wherein, Coolant outlet hose one end but is connected in the loop with electric generator inner cooling; The other end is connected with reflow pipe with user's heat exchanger, solenoid valve A, breed pond heat exchanger, the water tower that dries in the air, temperature transducer respectively; Superconducting heat pipe is formed an integral body with breed pond heat exchanger, and temperature detect switch (TDS) is connected with temperature transducer, solenoid valve A and solenoid valve B respectively through electric line.
Described user's heat exchanger is the heat-exchanging part that is connected in series with on the coolant outlet hose, and through the customer charge of certain thermal power, promptly radiator is taken away the partial heat energy in the cooling water, has reduced the heat radiation workload of the water tower that dries in the air.
Described breed pond heat exchanger is provided with the sealed cavity of interface tube by two ends and is distributed in the extraordinary heat exchanger that the superconducting heat pipe that is obliquely installed of chamber outer surface is formed in a large number; Superconducting heat pipe passes and is sealed in the outer surface of sealed cavity, is the rising state from inside to outside and arranges.
Described temperature detect switch (TDS) is to gather signal and trigger switch circuit by temperature transducer, with intelligent switch parts such as electric consumer such as control electromagnetic valve.
When the present invention uses, by the but high-temperature cooling water that flows out of loop of electric generator inner cooling, successively through behind user's heat exchanger, solenoid valve B, the water tower that dries in the air; Detect through temperature transducer again, turn back to electric generator inner cooling again but in the loop through reflow pipe, too high if temperature transducer detects the temperature of recirculation water; Just trigger the temperature detect switch (TDS) preset action, close solenoid valve B, open solenoid valve A; Make the too high recirculation water of temperature directly not get into the water tower that dries in the air through solenoid valve B, promptly culture the pond heat exchanger but increased new return flow line, the residue heat energy that makes recirculation water is through culturing the superconducting heat pipe of pond heat exchanger; Be discharged in the flowing water of culturing the pond, enter into the water tower that dries in the air again after further reducing temperature, enter into but loop of electric generator inner cooling through reflow pipe; Because the cooling circuit and the heat exchange circulatory system are sealed in the whole generating machine; In output residue heat energy, guaranteed the stable of water quality, have reasonable in design, simple in structure, reliable advantage.
