Technical Field

[0001] The invention relates to the technical field of lithium bromide units, and in particular to a lithium bromide unit with a refrigeration capacity recovery and utilization structure. Background Art

[0002] In lithium bromide absorption refrigeration, water is used as the refrigerant and lithium bromide is used as the absorbent. Since lithium bromide aqueous solution has a high boiling point and is extremely difficult to evaporate, the steam on the surface of the saturated lithium bromide solution can be considered to be pure water vapor. At a certain temperature, the saturated partial pressure of water vapor on the surface of lithium bromide aqueous solution is less than the saturated partial pressure of pure water. Moreover, the higher the concentration, the smaller the saturated partial pressure of water vapor on the surface. Therefore, under the same temperature conditions, the greater the concentration of lithium bromide aqueous solution, the stronger its ability to absorb water. This is why lithium bromide is usually used as the absorbent and water as the refrigerant. The lithium bromide absorption refrigerator is mainly composed of a generator, a condenser, an evaporator, an absorber, a heat exchanger, a circulating pump, etc. In lithium bromide absorption refrigeration, water is used as the absorbent and the refrigerant is used as the absorbent. The lithium bromide absorption refrigerator is mainly composed of a generator, a condenser, an evaporator, an absorber, a heat exchanger, a circulating pump, etc. During the operation of the lithium absorption refrigeration machine, when the lithium bromide aqueous solution is heated by the heating steam in the generator, the water in the solution is continuously vaporized; as the water is continuously vaporized, the concentration of the lithium bromide aqueous solution in the generator continues to increase and enters the absorber; the water vapor enters the condenser, is cooled by the cooling water in the condenser and condenses to become high-pressure and low-temperature liquid water; when the water in the condenser enters the steam generator through the throttle valve, it expands rapidly and vaporizes, and absorbs a large amount of heat from the refrigerant water in the evaporator during the vaporization process, thereby achieving the purpose of cooling; in this process, the low-temperature water vapor enters the absorber, is absorbed by the lithium bromide aqueous solution in the absorber, and the concentration of the solution is gradually reduced, and then sent back to the generator by the circulating pump to complete the entire cycle. This cycle continues endlessly, and cold is continuously produced. Since the lithium bromide dilute solution has been cooled in the absorber and has a low temperature, in order to save heat for heating the dilute solution and improve the thermal efficiency of the entire device, a heat exchanger is added to the system to allow the high-temperature concentrated solution flowing out of the generator to exchange heat with the low-temperature dilute solution flowing out of the absorber, thereby increasing the temperature of the dilute solution entering the generator; Patent: CN219511050 U discloses a steam-type double-effect lithium bromide unit for heating and cooling, including a unit body, a base and a mounting seat, the base is fixed below the unit body to provide support for the unit body, and a mounting seat is fixed on the outside of the base, the base is installed and fixed by the mounting seat, a running wheel is arranged below the base, and a steering wheel is arranged on the left side of the running wheel.

[0003] The structural technology of lithium bromide units currently on the market is relatively complete, but traditional lithium bromide units do not have the ability to recover the cooling capacity for heat dissipation protection of the unit's electrical control box, and cannot recover the steam pressure for circulating pumping of cooling water. Traditional lithium bromide units are easily contaminated by dust and are inconvenient to maintain in the later stage.

When the pressure in the telescopic liquid capsule 4 reaches the threshold value of the adjustable pressure relief valve 708, the excess cooling water is pumped out through the cooling water inlet pipe 213, the cooling water enters the turbine disc 209 and is output through the water delivery elbow 211, and is input into the end tube 201 through the second rotary joint 212 and the rotating tube 204. In the annular tube 202 and the folded condenser tube 203, the cooling water is then drained through the first rotary joint 208 and the cooling water drainage elbow 207. During the circulation of the cooling water, the cooling water flowing in the turbine disk 209 will impact the internal impeller 210, thereby driving the rotating tube 204 to rotate, thereby driving the annular tube 202 and the folded condenser tube 203 in the end tube 201 to rotate. The first rotary joint 208 and the second rotary joint 212 are set so that the rotating tube 204 does not affect the pumping of the cooling water during the rotation process. The rotating tube 204 drives the suction blade 206 to rotate in the end tube 201, and the water vapor in the condenser 11 is sucked under the centrifugal action, so that the water vapor enters the end tube 201 and the annular tube 202. The condenser 11 in the lithium bromide unit is fully in contact with the folded condenser tube 203, which greatly improves the condensation efficiency of the condenser 11 in the lithium bromide unit. The cooling water is discharged through the cooling water drainage elbow 207, so that the cooling water flows back to the water injection pool 702 and flows into the closed water tank 701 through the through pipe 703. The first one-way valve 704 is set to prevent the cooling water in the closed water tank 701 from flowing back, and the pressure of the steam in the lithium bromide unit is recovered to carry out the circulating pump of the cooling water. The cooling water is input into the telescopic liquid capsule 4 and covered on the outer wall of the lithium bromide unit, so as to realize the recycling of the refrigeration capacity of the lithium bromide unit, play a role in heat dissipation protection for the external electric control box structure of the lithium bromide unit, and also play a role in sound insulation of the lithium bromide unit. The user can use the mounting column 801, the step rod 802 and the side The ladder structure composed of the beam 803 is climbed, which is convenient for the maintenance of the top of the lithium bromide unit in the later stage. When the lithium bromide unit is in use, the step rod 802 and the side beam 803 can be flipped around the mounting column 801. During the flipping process, the end of the engaging spring piece 805 will be gradually clamped into the tooth groove of the gear 804, so that the step rod 802 and the side beam 803 are fixed after the flip adjustment, so that the brush 806 on one side of the side beam 803 contacts the outer wall of the lithium bromide unit, and the pumping of the above cooling water is controlled, and the injection of cooling water in the telescopic liquid capsule 4 is controlled, and the movement of the n-type frame 3 is controlled. The movement of the n-type frame 3 drives the brush 806 to move on the outer wall of the lithium bromide unit, and the brush 806 sweeps the outer wall of the lithium bromide unit to clean the dust, which is convenient for the maintenance of the lithium bromide unit. ;
