Description
Technical Field

In the production process or life, air conditioning is required to cool or heat, and a certain energy source is required to be consumed for realizing the cooling or heating. Meanwhile, a large amount of medium (low) temperature waste heat exists in the production process, and some waste heat is discharged due to unavailable use, so that waste is caused. In order to save energy and reduce emission, the lithium bromide refrigeration technology is utilized, and the part of waste heat can be recycled, so that the purpose of refrigeration or heating is realized. In general, when the temperature of the waste heat water inlet is about 90 ℃ and refrigeration is needed, the first-choice product is a hot water single-effect lithium bromide absorption chiller (the flow chart is shown in figure 1), and the temperature of the waste heat water outlet is at the lowest 80 ℃ and the temperature difference between the waste heat water inlet and the waste heat water outlet is at the highest 10 ℃ because the refrigeration coefficient COP of the chiller can reach about 0.75; if the secondary generation secondary absorption hot water type lithium bromide absorption chiller unit (the flow chart is shown in figure 2) is selected to prepare cold water with the same quality, the temperature difference between the waste heat water inlet and outlet is increased to about 30 ℃, the temperature of the hot water outlet is reduced to 60 ℃, and the heat recovery of the waste heat water with the same flow is more, but the coefficient of performance COP is only about 0.4, and obviously, the conversion efficiency is too low. How to make the middle (low) temperature waste heat water have large cooling range, and can recover more middle (low) temperature waste heat water heat and have higher coefficient of performance (COP) value, and the preparation of cold water with the same quality meets the requirements of production process or living use, thereby realizing the comprehensive economic and social benefits of energy conservation and emission reduction, and becoming one of the important subjects of the current research.
Disclosure of Invention
The invention aims to provide a hot water type lithium bromide absorption chiller with single-effect generation solution series connection, which ensures that the temperature reduction range of middle (low) temperature waste heat water is large, more waste heat water heat can be recovered, and the coefficient of performance COP value is higher.
The invention aims at realizing the following steps: a hot water type lithium bromide absorption chiller with single effect generating solution connected in series comprises a single effect generator, a secondary generator, a condenser, an evaporator, a secondary absorber, a primary generator, a primary heat exchanger, a secondary heat exchanger, a single effect heat exchanger, a refrigerant pump, a secondary generating pump, a primary generating pump, a single effect generating pump, a control system, pipelines, valves and the like for connecting the components. The method is characterized in that: on the basis of a secondary generation secondary absorption hot water type lithium bromide absorption chiller, an added single-effect generator is arranged in a high-pressure cavity of an upper cylinder secondary generator and a condenser, and an independent liquid receiving disc is arranged on the single-effect generator and is arranged above the secondary generator; the evaporator and the secondary absorber are in the same low-pressure cavity, the primary generator and the primary absorber are in the same medium-pressure cavity, and the primary generator and the primary absorber are placed in the lower cylinder. Driving hot water to enter the single-effect generator first, then enter the primary generator, and finally enter the secondary generator; the cooling water enters the second-stage absorber firstly and then enters the first-stage absorber, and finally enters the condenser; cold water enters the evaporator. The solution circulation in the unit is divided into two relatively independent circulation: the secondary generator, the primary absorber and the secondary heat exchanger form a secondary solution circulation; the dilute solution from the secondary absorber is lifted by the primary generating pump, is heated by the primary heat exchanger and enters the primary generator to be heated and concentrated into an intermediate solution, the intermediate solution from the primary generator is lifted by the single-effect generating pump, is heated by the single-effect heat exchanger and enters the single-effect generator to be heated and concentrated into a concentrated solution, the concentrated solution from the single-effect generator is cooled by the single-effect heat exchanger and the primary heat exchanger in turn by the pressure difference and the power of the potential difference and enters the secondary absorber to be sprayed into the dilute solution, and the process forms another single-effect and primary solution serial circulation.
The single-effect generator, the secondary generator and the condenser are positioned in the same high-pressure cavity and are arranged at the upper part of the unit, the single-effect generator and the secondary generator can be arranged side by side, an independent liquid receiving disc is arranged, and a liquid baffle is arranged between the single-effect generator and the secondary generator.
The driving waste heat in the above scheme can be waste hot water, heat conducting oil or other mediums. The cooling water can be firstly connected in parallel to enter the secondary absorber and the primary absorber and then be converged together to enter the condenser. The cooling water may also be fed in parallel to the secondary absorber, the primary absorber and the condenser.
Compared with the prior art, the invention has the advantages that:
the invention makes the residual water release heat in the high temperature area in the single-effect generator, release heat in the medium temperature area in the first-stage generator and release heat in the low temperature area in the second-stage generator through the newly added single-effect generator and single-effect heat exchanger and the brand new flow, reasonably utilizes the residual heat water temperature area, simultaneously makes the pressure of the medium pressure cavity relatively improved through the single-effect and first-stage solution serial circulation, more reasonably selects the temperature point and concentration difference of each circulation, improves the coefficient of performance COP value of the unit, and the concentrated solution of the single-effect generator enters the second-stage absorber to spray after being cooled by the single-effect heat exchanger and the first-stage heat exchanger by the power of the pressure difference and the potential difference, without adding a power pump, and still uses four shielding pumps. The refrigerating performance coefficient of the solution circulation of the single-effect generator is basically the same as that of the hot water single-effect type unit, the refrigerating performance coefficients of the solution circulation of the second-stage solution and the solution circulation of the first-stage generator are basically the same as those of the second-stage hot water type unit, and the two are compounded to ensure that the hot water type unit with the single-effect generation solution connected in series can improve the coefficient of performance COP (coefficient of performance) when the heat of residual hot water is recovered more. For example, when the temperature of the waste heat water inlet is about 90 ℃, the same grade cold water (about 8 ℃ of the cold water outlet) as that of the single-effect type unit and the secondary type unit is prepared, the hot water type lithium bromide absorption type water chilling unit with single-effect generation solution connected in series is adopted, the coefficient of performance COP can reach about 0.6, the temperature difference between the waste heat water outlet and the waste heat water inlet is about 55 ℃, and the temperature difference between the waste heat water inlet and the waste heat water outlet can reach about 35 ℃, therefore, the coefficient of performance COP of the unit is slightly lower than that of the single-effect type unit but is greatly improved than that of the secondary type unit, the temperature reduction amplitude of hot water is increased, the heat of the waste heat can be fully recycled, and the comprehensive economic and social benefits of energy conservation and emission reduction are realized.

Detailed Description
The invention is described in further detail below with reference to the embodiments of the drawings.
Example 1:
the hot water type lithium bromide absorption chiller with single effect generating solution series connection as shown in fig. 3 comprises a single effect generator 19, a secondary generator 16, a condenser 2, an evaporator 3, a secondary absorber 8, a primary absorber 9, a primary generator 14, a primary heat exchanger 13, a secondary heat exchanger 15, a single effect heat exchanger 18, a refrigerant pump 5, a primary generating pump 10, a secondary generating pump 11, a single effect generating pump 17, a control system (not shown in the figure), pipelines connecting all components, valves and the like. On the basis of the traditional secondary generation secondary absorption hot water type lithium bromide absorption water chilling unit (shown in figure 2), a single-effect generator 19 is arranged in a high-pressure cavity of an upper cylinder secondary generator 16 and a condenser 2, and the single-effect generator 19 is provided with an independent liquid receiving disc and is arranged above the secondary generator 16; the evaporator 3 and the secondary absorber 8 are in the same low pressure chamber, and the primary generator 14 and the primary absorber 9 are in the same medium pressure chamber, still placed in the lower drum. The unit flow drives hot water to enter the single-effect generator 19 first, then enter the primary generator 14 and finally enter the secondary generator 16; the cooling water enters the secondary absorber 8, then enters the primary absorber 9, and finally enters the condenser 2; cold water enters the evaporator 3. The solution circulation in the unit is divided into two relatively independent circulation: the secondary generator 16, the primary absorber 9 and the secondary heat exchanger 15 form a secondary solution cycle; the dilute solution from the secondary absorber 8 is lifted by the primary generating pump 10, is heated by the primary heat exchanger 13 and enters the primary generator 14 to be heated and concentrated into an intermediate solution, the intermediate solution from the primary generator 14 is lifted by the single-effect generating pump 17, is heated by the single-effect heat exchanger 18 and enters the single-effect generator 19 to be heated and concentrated into a concentrated solution, and the concentrated solution from the single-effect generator enters the secondary absorber 8 to be sprayed into the dilute solution after being cooled by the single-effect heat exchanger 18 and the primary heat exchanger 13 in sequence by the power of pressure difference and potential difference, wherein the process forms another single-effect and primary solution serial circulation.
Because the single-effect generator 19 and the secondary generator 16 are positioned in the same high-pressure cavity with the condenser 2, the single-effect generating pressure is the same as the secondary generating pressure, hot water firstly enters the single-effect generator 19, the temperature of the hot water is correspondingly higher, and the intermediate solution from the primary generator 14 is heated and concentrated into high-concentration concentrated solution in the single-effect generator 19; the hot water finally enters the secondary generator 16, the temperature of the hot water is the lowest, and the low-concentration dilute solution from the primary absorber 9 is heated and concentrated into a low-concentration concentrated solution in the secondary generator 16 under the same generating pressure condition; in the medium-pressure cavities of the first-stage generator 14 and the first-stage absorber 9, the low-concentration concentrated solution from the second-stage generator 16 enters the first-stage absorber 9 for spraying, the refrigerant steam generated by the first-stage generator 14 is absorbed, heat is taken away by cooling water, medium first-stage generation pressure is formed, and the dilute solution from the second-stage absorber 8 is heated and concentrated into an intermediate solution in the first-stage generator 14. In the low-pressure cavities of the evaporator 3 and the secondary absorber 8, the refrigerant water condensed by the condenser 2 enters the evaporator 3 through a U-shaped pipe to absorb heat and evaporate to refrigerate, and the concentrated solution in the secondary absorber 8 absorbs the refrigerant steam and becomes a dilute solution.
The single-effect generator 19, the secondary generator 16 and the condenser 2 are positioned in the same high-pressure cavity and are arranged at the upper part of the unit.
Through the brand new optimization flow, the hot water type lithium bromide absorption type water chilling unit with single-effect generation solution series connection is formed, so that the middle (low) temperature waste heat water has large cooling range, more waste heat recovery coefficient of performance COP value is improved, and the comprehensive economic and social benefits of energy conservation and emission reduction are realized.

The cooling water can be firstly connected in parallel to enter the secondary absorber 8 and the primary absorber 9 and then be converged together to enter the condenser 2. The cooling water may also be fed in parallel to the secondary absorber 8, the primary absorber 9 and the condenser 2.
