Description

Technical Field

[0001] The utility model relates to the technical field of water cooling devices, in particular to a water circulation cooling low-temperature and low-consumption device. Background Art

[0002] The pre-cooling system is an important component of the operation of the air separation unit. It is connected in series between the air compressor system and the molecular sieve adsorption system to reduce the air temperature and moisture content when the air enters the molecular sieve adsorber. Reasonable use of the air pre-cooling system is conducive to the long-term and safe operation of the air separation equipment, especially in high temperature seasons.

[0003] An existing Chinese utility model patent with reference publication number CN117098367A discloses a low-carbon, low-water consumption circulating cooling system for high-power water-cooled inverters, belonging to the field of inverter heat dissipation technology. The system comprises a medium-voltage inverter cabinet for mounting electrical components, a cooling and cooling pipe assembly mounted on the inner wall of the medium-voltage inverter cabinet, and an input and output end of the cooling and cooling pipe assembly. A hot water return pipe is connected to the output end of the cooling and cooling pipe assembly, and a cold water supply pipe is connected at one end to the input end of the cooling and cooling pipe assembly. The present invention circulates coolant within the cooling pipes. As the coolant flows through the cooling and cooling pipe assembly, it absorbs heat within the medium-voltage inverter cabinet, thereby reducing the temperature within the cabinet. The heat-increasing coolant is then discharged through the hot water return pipe, cooled by the refrigeration assembly, and then reintroduced into the cooling and cooling pipe assembly through the cold water supply pipe, thereby completing the cooling operation of the medium-voltage inverter cabinet.

[0004] Based on the search of the above patents and combined with the equipment found in the prior art, the chiller is an electric driven refrigerator with a designed cooling capacity of 60×10 4 kcal / h, the theoretical cooling water capacity is 120Nm 3 / h, the design cold water inlet temperature is 12℃, and the cold water outlet temperature is 7℃. In hot seasons, the cold water inlet temperature is often as high as 20℃, which causes the air outlet temperature of the air cooling tower to be higher than the design value, resulting in high temperature and water content of the air entering the molecular sieve adsorber, which reduces the capacity of the molecular sieve to adsorb hydrocarbons and carbon dioxide, and reduces the reliability of the safe operation of the air separation. The design cooling water inlet temperature of the electric refrigerator is 30℃, and the return water temperature is 35℃. In hot weather, the inlet and return water temperatures are both greater than the design values, which reduces the cooling capacity of the refrigerant. In hot weather, the cooling effect of the water cooling tower decreases due to the increase in water system temperature, which increases the temperature of the cold water entering the refrigeration unit. It requires more cooling capacity to cool the cold water, thus affecting the performance of the electric refrigerator. The existence of these problems affects the use of the device.

[0019] 1. The utility model sets up the whole device, which retains the original cooling unit device and re-configures a steam-driven refrigerator in parallel. The new refrigerator uses free steam as the driving heat source, lithium bromide solution as the absorbent, and water as the refrigerant. It is a device for producing cold water under vacuum. The working cycle of the lithium bromide refrigeration unit can be subdivided into four stages: adsorption process, condensation process, desorption process and evaporation process. In these stages, the refrigerant lithium bromide releases or absorbs heat during the adsorption, condensation, desorption and evaporation processes, thereby achieving a cooling effect, reducing the cold water inlet temperature from 19°C to 9°C, and the cooling water inlet and return temperature from 32°C to 40℃, which improves the refrigeration effect of the refrigeration unit, reduces the power consumption of the refrigeration unit, and reduces carbon emissions, thereby achieving the purpose of energy saving.

It effectively prevents the cooling effect of the water-cooled tower from decreasing due to the temperature increase of the water system in high temperature weather, which causes the temperature of the cold water entering the refrigeration unit to rise. It requires more cooling capacity to cool the cold water, thus affecting the performance of the electric refrigerator. BRIEF DESCRIPTION OF THE DRAWINGS

The high-voltage generator 202 and the high-temperature heat exchanger 203 are connected by a delivery pipe. The high-voltage generator 202 heats the absorbent, which is a lithium bromide solution.

[0033] Through the above structure: the high-voltage generator 202 at the upper end is connected by installing the mounting plate 201, which is convenient for subsequent use.

[0034] See also Figure 1 - Figure 4 A vacuum pump 302 is installed at the rear end of the part structure assembly 3, the low-pressure generator 301 is installed on the upper right side of the high-pressure generator 202, the low-temperature heat exchanger 304 is installed on the upper right side of the low-pressure generator 301, and the low-temperature heat exchanger 304 and the solution pump 305 are installed on the same straight line.

[0035] Through the above structure: by installing the low-pressure generator 301, the lithium bromide solution is heated to gasify it and generate absorbent vapor. The vacuum pump 302 is installed at the rear end of the low-pressure generator 301, which is convenient for the subsequent extraction of air or gas in the container and the subsequent formation of a vacuum state. The refrigerant pump 303 is installed on the right side of the upper end of the low-pressure generator 301, which is convenient for the subsequent compression of the refrigerant from a low-temperature and low-pressure state to a high-temperature and high-pressure state, which is convenient for the subsequent release of heat and ultimately achieving a refrigeration effect. The low-temperature heat exchanger 304 is installed at the front end of the refrigerant pump 303, which is convenient for the subsequent heating at different temperatures. Heat is transferred between the fluids. The solution pump 305 is installed at the front end of the low-temperature heat exchanger 304 to facilitate the subsequent movement of liquid or gas from a low place to a high place. The evaporator 306 is installed at the upper end of the low-pressure generator 301 to facilitate the subsequent condensation of the refrigerant vapor into a liquid state, thereby absorbing heat and achieving a cooling effect. The absorber 307 is installed at the side end of the evaporator 306 to facilitate the subsequent chemical reaction between the lithium bromide solution and the gaseous refrigerant to form a concentrated solution. The condenser 308 is installed at the upper end of the absorber 307 to facilitate the subsequent cooling of the lithium bromide vapor through the cooler to turn it into a liquid state.

[0036] During use, first, the dilute solution is transferred to the high-pressure generator 202 by the solution pump 305. When the solution is heated to the boiling point by steam, high-temperature refrigerant steam is generated, which is introduced into the low-pressure generator 301 to heat the dilute solution in the low-pressure generator 301, and then enters the condenser 308 after throttling. The condenser 308 is cooled to become refrigerant water. The refrigerant water generated by the high-pressure generator 202 and the low-pressure generator 301 are combined through the condenser 308 collection tray and then introduced into the evaporator 306, heating the dilute solution steam in the high-pressure generator 202 to condense into water, and enters the condensate pipeline through the condensate regenerator. The dilute solution in the high-pressure generator 202 is heated and evaporated, so that the concentration increases to become a concentrated solution, and is then introduced into the absorber 307 through the high-temperature heat exchanger 203. The dilute solution in the low-pressure generator 301 is heated to release refrigerant steam and also becomes a concentrated solution, and then enters the absorber through the low-temperature heat exchanger 304. In the absorber 307, the two solutions are mixed to form an intermediate concentration solution, which is then transported to the spray system by the absorption pump and sprayed on the outer surface of the absorber 307 tube cluster, absorbing the refrigerant vapor from the evaporator 306, and becoming a dilute solution again to enter the next cycle. Since cooling water circulates in the condenser 308 tube cluster, when the refrigerant vapor generated by the high-pressure generator 202 and the low-pressure generator 301 condenses on the outer surface of the tube cluster, its heat is absorbed by the cooling water. The condensed refrigerant water is sprayed on the outer surface of the evaporator 306 tube cluster through the throttling device. Under the influence of the pressure in the evaporator 306, part of the refrigerant water evaporates and absorbs the heat of the cold water, producing a partial cooling effect. The majority of the refrigerant water that has not yet evaporated is sprayed on the outer surface of the evaporator 306 tube cluster by the refrigerant pump 303, absorbing the heat of the cold water flowing through the tube cluster, thereby lowering the temperature of the refrigerant water, thereby achieving the purpose of cooling.
