Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
Fig. 2 is a structural diagram of a power plant condensation heat recycling system according to the present invention. As shown in fig. 2, the system includes: a condenser 202, a high-temperature heat pump 204, a water cooling tower 208, a heating network 205 of a city where the power plant is located, a heater 203, a boiler 207, and a turbine 201. The generator 206 in fig. 2 is a plant of a power plant. Here, the high temperature heat pump 204 is a heat transfer device that transfers heat energy of a low temperature heat source to a high temperature heat source, and is particularly used to convert low-grade heat energy in the low temperature heat source into high-grade heat energy by a small amount of electric power and supply the high-grade heat energy to the high temperature heat source. The low-grade heat source in the invention refers to condensation heat, and the utilization difficulty is extremely high.
In fig. 2, a steam turbine 201, a boiler 207 and a heater 203 are all located in an electric power plant, and the steam turbine 201 drives a generator 206 to generate electricity under the action of steam with high internal temperature, so that heat energy in the steam is converted into electric energy generated by the generator 206. In the present invention, the steam comes from the sequential heating of the water by the heater 203 and the boiler 207. The steam used by the steam turbine 201 contains a large amount of condensation heat, and the temperature is still high, which is called as high-temperature steam in the invention.
The condenser 202 is connected to the turbine 201 and the high temperature heat pump 204, respectively, and is configured to receive high temperature steam containing condensation heat from the turbine 201, the high temperature steam loses condensation heat in the condenser 202, and the condenser 202 sends water obtained by the high temperature steam losing condensation heat to the high temperature heat pump 204.
The heater 203 is connected to the boiler 207, the turbine 201, and the high temperature heat pump 204, respectively, and the boiler 207 is connected to the turbine 201. In this way, the heater 203 heats the water sent from the high-temperature heat pump 204 by the high-temperature steam sent from the turbine 201, and then sends the obtained hot water to the boiler 207 to heat, thereby obtaining steam with an extremely high temperature. Of course, the heater 203 may also provide a certain amount of heat to further improve the heating effect. Then, the boiler 207 sends the heated steam to the turbine 201 to drive the turbine to operate. The operation of the turbine 201 may drive a generator 206 within the plant to generate electricity. Of course, the boiler 207 may have a function of pressurizing steam to increase the pressure of the steam entering the turbine 201, thereby improving the power generation efficiency. It can be seen that the steam is recycled inside the steam turbine 201, the condenser 202, the heater 203, the boiler 207 and the corresponding pipelines, which constitutes the first cycle of water resource utilization according to the present invention.
The water cooling tower 208 is connected to the inside of the condenser 202 through a water inlet line 2041 and a water outlet line 2042, respectively, and the water inlet line 2041 and the water outlet line 2042 are in closed communication with each other inside the condenser 202. Thus, the cooling tower 208 can send the chilled water with a lower temperature into the condenser 202 through the water inlet line 2041, the chilled water absorbs the heat of condensation in the high-temperature steam in the condenser 202, and the temperature of the chilled water is increased to become hot water, and the hot water enters the cooling tower 208 along the water outlet line 2042. It can be seen that the condenser 202, the water cooling tower 208, and the inlet line 2041 and the outlet line 2042 form a second circulation loop for water resource utilization, and the chilled water and the hot water are circulated in the second circulation loop for heat absorption and transfer.
In order to improve the heat exchange efficiency of the condenser 202, the contact area of the water inlet line 2041 with the high-temperature steam in the condenser 202 may be increased as much as possible.
The high temperature heat pump 204 is connected in parallel with the water cooling tower 208, as shown in fig. 2, the high temperature heat pump 204 is connected to the water inlet line 2041 and the water outlet line 2042 through two lines, respectively, so as to connect in parallel with the water cooling tower 208. The high temperature heat pump 204 is also in communication with a heating network 205. Thus, the high temperature heat pump 204 can transfer the heat absorbed from the water in the water cooling tower 208 to the water supplied from the heating network 205 and the condenser 202, and supply the water supplied from the condenser 202 to the heater 203 for use by each household of the heating network. In the invention, the high-temperature heat pump 204, the heating network 205 and the corresponding pipeline form the third cycle of water resource recycling, and finally the condensation heat generated by the power plant is supplied to each family of the heating network for use.
Therefore, in the invention, the chilled water entering the condenser is changed into hot water after absorbing the condensation heat in the high-temperature steam and enters the water cooling tower, and the high-temperature heat pump transfers the heat in the hot water to the heating network through heat exchange, so that the recycling and the utilization of the condensation heat generated by the power plant are realized, the utilization rate of the heat energy is improved, the energy is saved, and the environment is protected. Meanwhile, the water in the invention is recycled in the three circulation rings, namely the high-temperature steam is changed into water after losing the heat of condensation, and the water is reheated by the heater and the boiler and then is reused for power generation, thereby forming the first circulation ring for water resource utilization; the hot water is changed into chilled water again after the heat is transferred by the high-temperature heat pump, and the chilled water is sent to the condenser by the water cooling tower to absorb the condensation heat, so that a second circulation loop for water resource utilization is formed; the heating water loses heat in the heating network and returns to the high-temperature heat pump to transfer heat again, and a third circulation loop for recycling water resources is formed. Therefore, the invention also realizes the reutilization of water resources, and compared with the continuous loss of water in the water cooling tower in the prior art, the invention greatly saves the water resources.
In the present invention, the chilled water absorbs the heat of condensation in the high-temperature steam inside the condenser 202, and the temperature of the chilled water rises to become hot water, which is generally lower than 40 ℃. The high temperature heat pump 204 absorbs heat from the water cooling tower 208 and transfers the heat to the heating return water in the heating network, and the heating return water receives the transferred heat and then increases in temperature to heating water temperature typically higher than 60 ℃. It can be seen that the high temperature heat pump 204 transfers heat from a low temperature heat source to a high temperature heat source (heating water in the present invention) having a temperature higher than 60 ℃, which cannot be achieved without using a high temperature heat pump.
The invention aims to improve the utilization efficiency of condensation heat of a power plant as much as possible, and the adopted mode is to transfer the condensation heat to an urban heating network by using a high-temperature heat pump. This is beneficial for saving energy and reducing consumption in large cities, but for small cities, for example, cities with 300 million people or less, the heat energy transferred by the high temperature heat pump may exceed the actual demand of the heating network, and at this time, in order to ensure that the condensation heat of the power plant can be sufficiently released, the excess condensation heat can be released into the atmosphere through the cooling function of the water cooling tower 208.
Because the heating network is used in severe cold seasons in winter, the heating network can not be used in other seasons, such as summer. However, the power plant is continuously producing, and the heat of condensation in the high temperature steam can be partially or completely absorbed by the cooling tower 208. Of course, to further utilize the heat of condensation, the high temperature heat pump 204 may further exchange heat with the water cooling tower 208, which in turn delivers the heat to the heater 203 for heating. According to this concept, as shown in fig. 2, the high temperature heat pump 204 is also connected to the heater 203. Thus, the high temperature heat pump 204 transfers the heat absorbed from the water in the water cooling tower 208 to the heater 203, which heats the water supplied from the condenser 202. The condensation heat generated by the power plant is fully utilized, and the heat energy utilization efficiency is improved.
Of course, the heat exchange between the high temperature heat pump 204 and the water cooling tower 208 and the heat supply from the high temperature heat pump 204 to the heater 203 are all accomplished by the carrying effect of water on heat.
Based on the system provided by the invention, a method for recycling the condensation heat of the power plant shown in FIG. 3 can be provided. As shown in fig. 3, the method includes:
step 301: a steam turbine in an electric power plant sends high-temperature steam containing condensation heat to a condenser and a heater respectively; the cooling tower sends the chilled water into the condenser through a water inlet pipeline.
In this step, high temperature steam contains a large amount of condensation heat, and the temperature is high, can not directly discharge into the atmosphere, otherwise can cause serious environmental heat to pollute, probably causes personnel's injury even, consequently will send to the condenser and condense, and the cooling water tower is sent to the inside refrigerated water of condenser and is exactly the condensation heat that is arranged in absorbing high temperature steam, in order to improve the heat exchange efficiency of condensation heat, can increase as far as possible the area of contact of water pipeline and high temperature steam in the condenser.
The steam turbine sends high-temperature steam to the heater, so that the high-temperature steam can heat water sent by the condenser in the heater.
Step 302: the chilled water absorbs the condensation heat in the high-temperature steam in the condenser, the temperature of the chilled water is increased to be changed into hot water, and the hot water enters the water cooling tower along the water outlet pipeline; the condenser sends the water which is formed by the high-temperature steam after losing the condensation heat to the high-temperature heat pump.
This step is a heat exchange process in which the heat of condensation is released from the high-temperature steam into the chilled water, raising the temperature of the chilled water to become hot water, which is typically at a temperature below 40 ℃.
The condenser is used for condensing high-temperature steam into water, and the water is heated by the high-temperature heat pump and then is further heated by the heater and the boiler, so that the water is changed into high-temperature steam again and returns to the steam turbine, and the steam turbine is pushed to drive the generator to generate electricity. The part of water resources circularly flow in the form of steam or water in the steam turbine, the heater and the condenser, and form a first circulation loop for utilizing the water resources.
In this step, the heater may further pressurize the steam with a high temperature generated by heating, so that the pressurized steam is sent to the steam turbine to improve the power generation efficiency of the present invention.
The chilled water enters the condenser from the water cooling tower along the water inlet pipeline, and is changed into hot water after absorbing condensation heat and returns to the water cooling tower along the water outlet pipeline, so that a second circulation loop for water resource utilization is completed, and no water resource is lost in the process.
Step 303: the high-temperature heat pump transfers the heat absorbed by the water in the water cooling tower to the water sent by a heating network and a condenser, and sends the water sent by the condenser to a heater; the heater heats the water sent by the high-temperature heat pump by using the high-temperature steam sent by the steam turbine, and then the water is further sent into the boiler to be heated into steam.
The high temperature heat pump is a heat transfer device, and this step transfers heat from a low temperature heat source to heating return water by the high temperature heat pump, so that the temperature of the heating return water is increased to become heating water, and the temperature of the heating water is usually higher than 60 ℃.
The heater utilizes the high-temperature steam sent by the steam turbine to heat the water sent by the high-temperature heat pump, and certainly, the heater can also have a heating function, so that the water sent by the condenser is further heated, and the heating effect is improved. The water heated in the heater is sent into a boiler for further heating, and finally, the steam with extremely high temperature is obtained through heating, and the steam can drive a steam turbine to rotate.
Step 304: the boiler sends the obtained steam into a steam turbine to drive the steam turbine to rotate, and then the steam turbine drives a generator to generate electricity.
As is known, a heating network in a city is used to heat each household in the city, and this process consumes heat in heating water, so that heating water with a higher temperature gradually changes into heating return water with a lower temperature.
Steps 303 and 304 realize a third circulation loop of water resources in the high temperature heat pump, the heating network and the corresponding pipelines, in which the water resources circulate, accompanied by the transfer (intake) of heat in the high temperature heat pump and the consumption (discharge) of heat in the heating network.
In the present invention, the chilled water sent from the water cooling tower to the interior of the condenser through the water inlet line absorbs the heat of condensation by utilizing the principle that the heat is transferred from the substance with higher temperature to the substance with lower temperature, so that the temperature of the chilled water is far lower than that of the high-temperature steam, for example, the temperature of the chilled water can be between 10 ℃ and 25 ℃.
In smaller cities, a cooling tower is also required to release excess heat of condensation if the heating network is not demanding enough heat.
In the seasons without using a heating network, such as summer, the condensation heat can be absorbed mainly by the water cooling tower. In order to improve the heat energy utilization efficiency, the high-temperature heat pump can absorb heat from the water cooling tower, and then the heat is transmitted to the heater to be heated and utilized.
It can be seen that the present invention has the following advantages:
(1) according to the invention, the chilled water entering the condenser is changed into hot water after absorbing the condensation heat in the high-temperature steam and enters the water cooling tower, and the high-temperature heat pump transfers the heat in the hot water to the heating network through heat exchange, so that the recycling and utilization of the condensation heat generated by the power plant are realized, the utilization rate of the heat energy is improved, the energy is saved, and the environment is protected. Meanwhile, the water in the invention is recycled in the three circulation rings, namely the high-temperature steam is changed into water after losing the heat of condensation, and the water is reheated by the heater and the boiler and then is reused for power generation, thereby forming the first circulation ring for water resource utilization; the hot water is changed into chilled water again after the heat is transferred by the high-temperature heat pump, and the chilled water is sent to the condenser by the water cooling tower to absorb the condensation heat, so that a second circulation loop for water resource utilization is formed; the heating water loses heat in the heating network and returns to the high-temperature heat pump to transfer heat again, and a third circulation loop for recycling water resources is formed. Therefore, the invention also realizes the reutilization of water resources, and compared with the continuous loss of water in the water cooling tower in the prior art, the invention greatly saves the water resources.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
