Description

Steam generation system based on jet-absorption heat pump 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 for a jet-absorption heat pump that features a rational process, simple structure, low manufacturing cost, wide applicability, and rationalized performance index.

Detailed implementation method:

[0052] 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.

[0053] The steam generation system based on the jet-absorption heat pump shown in Figure 1 is implemented as follows:

[0054] (1) Structurally, it mainly consists of an absorber, a solution pump, a solution heat exchanger, a generator, an ejector, a condenser, a booster pump, a steam generator, a throttle valve, an evaporator, 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 low-pressure steam inlet of the ejector 5; the ejector 5 also has a medium-pressure refrigerant vapor channel connected to the condenser 6; the condenser 6 also has a condensate pipeline connected to the steam generator 8 via the booster pump 7; the steam generator... The generator 8 also has a refrigerant vapor channel connected to the high-pressure steam inlet of the ejector 5. The condenser 6 also has a condensate pipeline connected to the evaporator 10 via the throttle valve 9. The evaporator 10 also has a refrigerant vapor 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 connected to the low-pressure steam inlet of the second ejector 11 via the absorber 1 and the condenser 6. The second ejector 11 also has a user steam channel connected to the outside. The steam generator 8 and the generator 4 also have high-temperature heat medium channels connected to the outside. The evaporator 10 also has a low-temperature heat medium channel connected to the outside.

[0055] (2) In terms of process, the dilute solution of absorber 1 enters generator 4 through solution pump 2 and solution heat exchanger 3. The high-temperature heat medium flows through generator 4, heats the solution inside, releases refrigerant vapor, and supplies it to ejector 5. The concentrated solution of generator 4 enters absorber 1 through solution heat exchanger 3, absorbs refrigerant vapor, and releases heat to the heated medium. The refrigerant vapor in condenser 6 releases heat to the heated medium to form condensate. The condensate discharged from condenser 6 is divided into two paths - the first path flows through throttling valve 9 to enter evaporator 10 to absorb heat and form refrigerant vapor, which is then supplied to absorber 1. The second path flows through booster pump 7 to boost pressure and then enters steam generator 8 to absorb heat and vaporize, and supplies it to ejector 5 as driving steam (working steam). The working steam enters ejector 5, flows through nozzles to reduce pressure and increase speed, and forms low pressure. The refrigerant vapor generated by generator 4 is drawn into ejector. In the low-pressure zone, the two steam streams mix and flow through a diffuser to reduce speed and increase pressure, forming medium-pressure steam which is then supplied to the condenser 6. The heated medium flows through the absorber 1 and condenser 6, gradually absorbing heat and vaporizing, before being supplied to the second ejector 11. External working steam enters the second ejector 11, flows through nozzles to reduce pressure and increase speed, forming low-pressure steam. Steam discharged from the condenser 6 is drawn into the second ejector 11. The two steam streams mix and flow through the diffuser to reduce speed and increase pressure, forming medium-pressure steam which is then supplied to the steam user. The high-temperature heat medium provides the driving heat load through the steam generator 8 and generator 4, and the external working steam provides the driving heat load through the second ejector 11. The heated medium obtains the heating load and vaporizes through the absorber 1 and condenser 6, while the low-temperature heat medium provides the low-temperature heat load through the evaporator 10, forming a steam generation system based on a jet-absorption heat pump.

[0056] The steam generation system based on the jet-absorption heat pump shown in Figure 2 is implemented as follows:

[0057] (1) Structurally, in the steam generation system based on the jet-absorption heat pump shown in Figure 1, 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 8 through the second booster pump 12. The steam generator 8 is equipped with a refrigerant steam channel that connects to the high-pressure steam inlet of the second ejector 11. The external channel that connects to the low-pressure steam inlet of the second ejector 11 after passing through the absorber 1 and condenser 6 is adjusted to an external channel that connects to the low-pressure steam inlet of the second ejector 11 after passing through the condenser 6 and absorber 1.
