Description

Technical fields:

[0001] This invention belongs to the field of combined heat and power technology. Background technology:

[0002] Combined heat and power (CHP) technology is an effective technical means to achieve efficient utilization of thermal energy. The important research contents of CHP technology include how to maintain the dominant position of the power subsystem, realize the deep utilization of waste steam resources, improve the working parameters of the heating subsystem, improve the coordination between the power subsystem and the heating subsystem, comprehensively utilize various resources, and reduce system manufacturing costs.

[0003] The ejector itself is a pressure boosting component, which has the advantages of simple structure, reliable operation, low investment and long service life; more importantly, the ejector can effectively adapt to high temperature heat loads - for heat pump systems, this is conducive to improving the rationalization of the driving heat load input link and expanding the utilization range of heat pump technology for high temperature heat loads.

[0004] Absorption heat pump heating technology has the advantages of low manufacturing cost and direct use of thermal energy as driving energy; however, its utilization depth, operating range and application fields are limited by the properties of the solution and refrigerant medium.

[0005] Traditional combined heat and power (CHP) technology faces constraints between heating load and power load. For example, when heating parameters are high, extraction steam heating and high back pressure heating have a significant impact on power output. In addition, how to make better use of exhaust steam resources is also worth studying.

[0006] Based on the principles of simple, proactive, and efficient energy utilization, this invention proposes a jet-absorption combined heat and power system with a reasonable process, simple structure, low manufacturing cost, good coordination, wide range of heating parameters, and rationalized performance index.

Detailed implementation method:

[0051] First, it should be noted that the structure and process are not repeated unless necessary; obvious processes are not described. The invention will now be described in detail with reference to the accompanying drawings and examples.

[0052] Figure 1 The jet-absorption combined heat and power system shown is implemented as follows:

[0053] (1) Structurally, it is mainly composed of an absorber, a solution pump, a solution heat exchanger, a generator, a condenser, a booster pump, a steam generator, a steam turbine, and an ejector. The absorber 1 has a dilute solution pipeline connected to the generator 4 via the solution pump 2 and the solution heat exchanger 3. The generator 4 also has a concentrated solution pipeline connected to the absorber 1 via the solution heat exchanger 3. The generator 4 also has a refrigerant vapor channel connected to the condenser 5. The condenser 5 also has a condensate pipeline connected to the steam generator 7 via the booster pump 6. The steam generator 7 also has a high-pressure steam channel connected to the steam turbine 8. The steam turbine 8 also has an extraction steam channel connected to the high-pressure steam inlet of the ejector 9. The steam turbine 8 also has a waste steam channel connected to the low-pressure steam inlet of the ejector 9. The ejector 10 also has a medium-pressure refrigerant vapor channel connected to the absorber 1. The steam generator 7 and the generator 4 also have high-temperature heat medium channels connected to the outside. The absorber 1 and the condenser 5 also have heated medium channels connected to the outside.

[0054] (2) In terms of process, the dilute solution in absorber 1 enters generator 4 via solution pump 2 and solution heat exchanger 3. The high-temperature heat medium flows through generator 4, heating the solution inside and releasing refrigerant vapor, which is then supplied to condenser 5. The concentrated solution in generator 4 enters absorber 1 via solution heat exchanger 3, absorbing refrigerant vapor and releasing heat to the heated medium. The refrigerant vapor in condenser 5 releases heat to the heated medium, forming condensate. The condensate in condenser 5 flows through booster pump 6 to be pressurized and then enters steam generator 7. The high-temperature heat medium flows through steam generator 7, heating the condensate inside and causing it to rise in temperature and vaporize. The steam generated by steam generator 7 enters steam turbine 8 to reduce pressure and perform work. After reaching a certain level, it is then distributed... The steam is supplied to the ejector 9 via two paths: the first path provides working steam to the ejector 9 through the extraction pipeline, and the second path continues to depressurize and work, becoming exhaust steam before entering the low-pressure zone of the ejector 9. The working steam enters the ejector 9, flows through the nozzles to depressurize and accelerate, and forms a low-pressure system. The exhaust steam discharged from the turbine 8 is drawn into the low-pressure zone of the ejector 9. After the two steam paths are mixed, they flow through the diffuser to depressurize and increase in pressure, forming medium-pressure steam, which is then supplied to the absorber 1. The high-temperature heat medium provides the driving heat load through the steam generator 7 and the generator 4. The heated medium obtains the heating load through the absorber 1 and the condenser 5. The solution pump 2 and the booster pump 6 consume mechanical energy, and the turbine 8 outputs mechanical energy, forming an ejector-absorption combined heat and power system.

[0055] Figure 2 The jet-absorption combined heat and power system shown is implemented as follows:

[0056] (1) Structurally, it mainly consists of an absorber, a solution pump, a solution heat exchanger, a generator, a condenser, a booster pump, a steam generator, a steam turbine, and an ejector; the absorber 1 has a dilute solution pipeline connected to the generator 4 via the solution pump 2 and the solution heat exchanger 3; the generator 4 also has a concentrated solution pipeline connected to the absorber 1 via the solution heat exchanger 3; the generator 4 also has a refrigerant vapor channel connected to the condenser 5; the condenser 5 also has a condensate pipeline connected to the steam generator 7 via the booster pump 6; and externally, there is a condensate pipeline connected to the steam generator 7. Steam generator 7 is connected to the turbine 8 via a high-pressure steam channel. Turbine 8 is also connected to the high-pressure steam inlet of ejector 9 via an extraction steam channel. Turbine 8 is also connected to the low-pressure steam inlet of ejector 9 via a waste steam channel. Turbine 8 is also connected to the outside via a waste steam channel. Ejector 10 is also connected to the absorber 1 via a medium-pressure refrigerant steam channel. Steam generator 7 and generator 4 are also connected to the outside via high-temperature heat medium channels. Absorber 1 and condenser 5 are also connected to the outside via heated medium channels.

[0057] (2) In terms of process, with Figure 1 Compared to the jet-absorption cogeneration system shown, the difference is that: the condensate at higher external pressure enters the steam generator 7, absorbs heat and vaporizes, and is supplied to the steam turbine 8. The exhaust steam discharged from the steam turbine 8 is divided into two paths - the first path is supplied to the ejector 9 and the second path is discharged to the outside, forming a jet-absorption cogeneration system.

[0058] Figure 3 The jet-absorption combined heat and power system shown is implemented as follows:

[0059] (1) Structurally, in Figure 2 In the jet-absorption combined heat and power system shown, the booster pump 6 and steam generator 7 are removed. The condenser 5 is connected to the steam generator 7 via the booster pump 6, and the condenser 5 is connected to the outside via the condenser 6.

[0105] (2) In terms of process, with Figure 3Compared to the jet-absorption combined heat and power system shown, the difference lies in the following: the dilute solution from absorber 1 flows through solution pump 2, solution heat exchanger 3, and second solution heat exchanger 13 into generator 4; the concentrated solution from generator 4 flows through second solution heat exchanger 13 into second absorber 14, absorbing refrigerant vapor and releasing heat to the heated medium; the dilute solution from second absorber 14 flows through solution heat exchanger 3 into absorber 1; externally high-pressure steam enters turbine 8 to reduce pressure and perform work, and after reaching a certain level, it is divided into three paths—the first path is supplied to ejector 9 through extraction steam pipeline as working steam, the second path is supplied through extraction steam pipeline... The first exhaust steam is supplied to the second injector 22 as working steam, and the third exhaust steam continues to be depressurized and does work, becoming waste steam. The first exhaust steam enters the low-pressure zone of the injector 9, the second exhaust steam enters the low-pressure zone of the second injector 22, and the third exhaust steam is discharged to the outside. The working steam enters the second injector 22, flows through the nozzle to reduce pressure and increase speed, and forms a low-pressure system. Part of the waste steam discharged from the turbine 8 is drawn into the low-pressure zone of the second injector 22. After the two steam streams are mixed, they flow through the diffuser to reduce speed and increase pressure, forming medium-pressure steam, which is then supplied to the second absorber 14. This increases the heating load of the heated medium through the second absorber 14, forming an injection-absorption combined heat and power system.

[0106] Figure 19 The jet-absorption combined heat and power system shown is implemented as follows:

[0107] (1) Structurally, in Figure 3 In the jet-absorption combined heat and power system shown, a second solution pump, a second solution heat exchanger, a second absorber, and a second ejector are added. The absorber 1 is connected to the generator 4 via a dilute solution pipeline through the solution pump 2 and the solution heat exchanger 3. The absorber 1 is then connected to the second absorber 14 via a dilute solution pipeline through the solution pump 2 and the solution heat exchanger 3. The second absorber 14 is then connected to the generator 4 via a dilute solution pipeline through the second solution pump 12 and the second solution heat exchanger 13. The generator 4 is connected to the absorber 1 via a concentrated solution pipeline through the solution heat exchanger 3. The generator 4 is then connected to the absorber 1 via a concentrated solution pipeline through the second solution heat exchanger 13 and the solution heat exchanger 3. The turbine 8 is equipped with an extraction steam channel connected to the high-pressure steam inlet of the second ejector 22. The turbine 8 is also equipped with an exhaust steam channel connected to the low-pressure steam inlet of the second ejector 22. The second ejector 22 also has a medium-pressure refrigerant steam channel connected to the second absorber 14. The second absorber 14 also has a heated medium channel connected to the outside.

[0108] (2) In terms of process, with Figure 3Compared to the jet-absorption combined heat and power system shown, the difference lies in the following: the dilute solution of absorber 1 flows through solution pump 2 and solution heat exchanger 3 into the second absorber 14, where it absorbs refrigerant vapor and releases heat to the heated medium. The dilute solution of the second absorber 14 flows through the second solution pump 12 and the second solution heat exchanger 13 into the generator 4. The concentrated solution of the generator 4 flows through the second solution heat exchanger 13 and solution heat exchanger 3 into the absorber 1. The external high-pressure steam enters the turbine 8 to reduce its pressure and perform work. After reaching a certain pressure, it is divided into two paths—the first path is supplied to the second ejector 22 through the extraction steam pipeline as working steam, and the second path continues to reduce its pressure. After performing work, the steam is divided into two streams: the first stream is supplied to ejector 9 as working steam, and the second stream continues to depressurize and perform work, becoming exhaust steam. The first stream exhaust steam enters the low-pressure zone of ejector 9, the second stream exhaust steam enters the low-pressure zone of second ejector 22, and the third stream exhaust steam is discharged to the outside. The working steam enters the second ejector 22, flows through the nozzle to depressurize and increase speed, and forms a low-pressure system. Part of the exhaust steam discharged from turbine 8 is drawn into the low-pressure zone of the second ejector 22. After the two streams of steam are mixed, they flow through the diffuser to depressurize and increase pressure, forming medium-pressure steam, which is then supplied to the second absorber 14. This increases the heating load of the heated medium through the second absorber 14, forming an ejector-absorption combined heat and power system.

[0109] Figure 20 The jet-absorption combined heat and power system shown is implemented as follows:

[0110] (1) Structurally, in Figure 2 In the jet-absorption combined heat and power system shown, a new ejector A is added. The refrigerant vapor passage of generator 4 is connected to condenser 5 and adjusted so that the refrigerant vapor passage of generator 4 is connected to the low-pressure steam inlet of the new ejector A. The steam passage connected to the high-pressure steam inlet of ejector 9 is divided into two paths - the first path is connected to the high-pressure steam inlet of ejector 9 and the second path is connected to the high-pressure steam inlet of new ejector A. The new ejector A also has a medium-pressure steam passage connected to condenser 5.

[0111] (2) In terms of process, with Figure 2 Compared to the jet-absorption cogeneration system shown, the difference lies in the following: the extraction steam from the turbine 8 is divided into two paths—the first path is supplied to the ejector 9 as working steam, and the second path is supplied to the newly added ejector A as working steam; the refrigerant steam generated by the generator 4 is supplied to the newly added ejector A, the working steam enters the newly added ejector A, flows through the nozzle to decrease pressure and increase speed to form a low pressure, and the refrigerant steam generated by the generator 4 is drawn into the low-pressure zone of the newly added ejector A. After the two steam paths are mixed, they flow through the diffuser to decrease speed and increase pressure to form medium-pressure steam and are supplied to the condenser 5, thus forming the jet-absorption cogeneration system.
