Description

Technical fields:

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

[0002] People need to use energy for cooling and efficient heating, which requires advanced heat pump technology; for variable-temperature heat resources, segmented utilization is an effective means to improve their utilization efficiency and value.

[0003] People need steam with different parameters in their lives and production processes. Compared with traditional steam production technology, it is obvious that using heat pump technology to provide steam is an important means to achieve energy efficiency and high-value utilization.

[0004] In practical applications, the operating parameters, performance index, manufacturing cost, and adaptability of heat pumps should be given priority and emphasis.

[0005] An ejector is a pressure-boosting component that effectively utilizes high-temperature heat resources. It has the advantages of simple structure, reliable operation, low investment and long service life. In addition, compared with compressors, ejectors are more adaptable to the compression of wet steam.

[0006] Absorption heat pumps have low manufacturing costs and also directly use thermal energy as the driving energy source; however, when users need steam, absorption heat pumps cannot directly produce steam in many cases due to the limitations of solution properties, refrigerant medium properties, and the quality of low-temperature heat resources; when users require high steam parameters, absorption heat pump technology is even more inadequate.

[0007] Based on the principles of simple, proactive, and efficient energy utilization for cooling / heating, this invention proposes a steam generation system based on a jet-absorption heat pump, which features a reasonable process, simple structure, low manufacturing cost, wide applicability, and the ability to achieve rationalized performance indices.

Detailed implementation method:

[0045] 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.

[0046] Figure 1 The steam generation system based on the jet-absorption heat pump shown is implemented as follows:

[0047] (1) Structurally, it mainly consists of an absorber, a solution pump, a solution heat exchanger, a generator, a condenser, a throttling valve, an evaporator, a booster pump, a steam generator, an ejector, and a second 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 evaporator 7 via the throttling valve 6; the evaporator 7 also has a refrigerant vapor channel connected to the low-pressure steam inlet of the ejector 10; the condenser 5 also has a refrigerant vapor channel connected to the low-pressure steam inlet of the ejector 10. The condensate pipeline is connected to the steam generator 9 via the booster pump 8. The steam generator 9 also has a refrigerant steam channel connected to the high-pressure steam inlet of the ejector 10. The ejector 10 also has a medium-pressure refrigerant steam channel connected to the absorber 1. There is an external working steam channel connected to the high-pressure steam inlet of the second ejector 11. There is an external heated medium channel that connects to the low-pressure steam inlet of the second ejector 11 after passing through the absorber 1 and the condenser 5. The second ejector 11 also has a user steam channel connected to the outside. The steam generator 9 and the generator 4 also have high-temperature heat medium channels connected to the outside. The evaporator 7 also has a low-temperature heat medium channel connected to the outside.

[0048] (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 to form condensate. The condensate in condenser 5 is divided into two paths: the first path flows through throttling valve 6 to enter evaporator 7 to absorb heat and form refrigerant vapor, and the second path flows through booster pump 8 to boost pressure and then enters steam generator 9 to absorb heat and vaporize, providing it to ejector 10 as driving steam (working steam). The working steam enters ejector 10, flows through nozzles to reduce pressure and increase speed, and forms a low-pressure zone. The refrigerant vapor generated in evaporator 7 is drawn into the low-pressure zone of ejector 10. After the two steam streams are mixed, they flow through a diffuser to reduce speed and increase pressure to form medium-pressure steam, which is then supplied to absorber 1. The heated medium flows through absorber 1 and condenser 5 to gradually absorb heat and vaporize, and is then supplied to the second ejector 11. External working steam enters the second ejector 11, flows through nozzles to reduce pressure and increase speed to form low pressure, and the steam discharged from condenser 5 is drawn into the low-pressure zone of the second ejector 11. After the two steam streams are mixed, they flow through a diffuser to reduce speed and increase pressure to form medium-pressure steam, which is then supplied to the steam user. The high-temperature heat medium provides the driving heat load through steam generator 9 and generator 4, and the external working steam provides the driving heat load through the second ejector 11. The heated medium obtains the steam supply load and vaporizes through absorber 1 and condenser 5, and the low-temperature heat medium provides the low-temperature heat load through evaporator 7, forming a steam generation system based on a jet-absorption heat pump.

[0049] Figure 2The steam generation system based on the jet-absorption heat pump shown is implemented as follows:

[0050] (1) Structurally, in Figure 1 In the steam generation system based on the jet-absorption heat pump shown, the working steam channel that connects to the high-pressure steam inlet of the second ejector 11 is removed, and a second booster pump 12 is added. An external liquid medium channel is connected to the steam generator 9 via the second booster pump 12. The steam generator 9 is equipped with a refrigerant steam channel that connects to the high-pressure steam inlet of the second ejector 11.

[0051] (2) In terms of process, with Figure 1 Compared to the steam generation system based on the jet-absorption heat pump shown, the difference is that: after the external liquid is pressurized by the second booster pump 12, it enters the steam generator 9, absorbs heat and vaporizes, and the steam generator 9 provides working steam to the second ejector 11, thus forming a steam generation system based on the jet-absorption heat pump.

[0052] Figure 3 The steam generation system based on the jet-absorption heat pump shown is implemented as follows:

[0053] (1) Structurally, in Figure 1 In the steam generation system based on the jet-absorption heat pump shown, the working steam channel that connects to the high-pressure steam inlet of the second ejector 11 externally is removed, and a second booster pump 12 and a second steam generator 13 are added. An external liquid medium channel is connected to the second steam generator 13 via the second booster pump 12. The second steam generator 13 also has a refrigerant steam channel that connects to the high-pressure steam inlet of the second ejector 11, and a high-temperature heat medium channel that connects to the outside.

[0054] (2) In terms of process, with Figure 1 Compared to the steam generation system based on the jet-absorption heat pump shown, the difference is that: after the external liquid is pressurized by the second booster pump 12, it enters the second steam generator 13. The high-temperature heat medium flows through the second steam generator 13 and heats the liquid inside to form high-pressure steam. The second steam generator 13 provides high-pressure steam to the second ejector 11 as working steam, thus forming a steam generation system based on the jet-absorption heat pump.

[0055] Figure 4 The steam generation system based on the jet-absorption heat pump shown is implemented as follows:

[0056] (1) Structurally, in Figure 1In the steam generation system based on the jet-absorption heat pump shown, a second generator, a second throttle valve, a second solution pump, and a second solution heat exchanger are added. The absorber 1 is equipped with a dilute solution pipeline that connects to the second generator 14 via the second solution pump 16 and the second solution heat exchanger 17. The second generator 14 also has a concentrated solution pipeline that connects to the absorber 1 via the second solution heat exchanger 17. The generator 4 is adjusted so that it has a refrigerant vapor channel that connects to the condenser 5. After the generator 4 has a refrigerant vapor channel that connects to the second generator 14, the second generator 14 also has a condensate pipeline that connects to the condenser 5 via the second throttle valve 15. The second generator 14 also has a refrigerant vapor channel that connects to the condenser 5.

[0057] (2) In terms of process, with Figure 1 Compared to the steam generation system based on the jet-absorption heat pump shown, the difference lies in the following: the refrigerant vapor generated by generator 4 is provided to the second generator 14 as the driving heat medium. Part of the dilute solution of absorber 1 enters the second generator 14 via the second solution pump 16 and the second solution heat exchanger 17. The refrigerant vapor flows through the second generator 14, heats the solution inside, releases refrigerant vapor, and is supplied to the condenser 5. The concentrated solution of the second generator 14 enters the absorber 1 via the second solution heat exchanger 17. The refrigerant vapor flowing through the second generator 14 releases heat and becomes condensate, which is then throttled by the second throttle valve 15 and enters the condenser 5, thus forming a steam generation system based on the jet-absorption heat pump.

[0058] Figure 5 The steam generation system based on the jet-absorption heat pump shown is implemented as follows:

[0059] (1) Structurally, in Figure 1 In the steam generation system based on the jet-absorption heat pump shown, a second generator, a second throttling valve, and a second solution heat exchanger are added.
