Description

Technical Field

[0001] The utility model relates to the technical field of cold dryers, in particular to a cold dryer for glass processing. Background Art

[0002] A cold dryer is short for a refrigerated dryer. The cold dryer uses a refrigerant to exchange heat with compressed air, reduces the temperature of the compressed air to the dew point temperature in the range of 2-10°C, and then removes the moisture in the air through a gas-liquid separator to obtain low-temperature and dry gas.

[0003] When the existing cold dryer cools down, the following defects exist. When the heat exchanger cools down the air, water vapor will condense into ice, thus blocking the evaporator and affecting the operation of the evaporator. Moreover, when drying the gas, the moisture in the gas cannot be completely removed, and the best effect cannot be achieved. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and a cold dryer for glass processing is proposed.

Support seats are fixedly connected to both ends inside the heat exchange pipe. A heat exchanger is rotatably connected to the middle of the two groups of support seats. A number of heat dissipation arms are evenly fixedly connected to the surface of the heat exchanger, and the inside of the heat exchanger and the heat dissipation arms are connected in communication. A synchronous pulley is fixedly connected to the surface of the end of the heat exchanger away from the transfer pipe.

[0006] As a further description of the above technical solution:

[0007] One end of the heat exchange tube away from the transfer tube is fixedly connected with a first turning tube. A second turning tube is arranged at the lower end of the first turning tube. One end of the second turning tube is fixedly connected with a first gas-liquid separator. The upper end of the first gas-liquid separator is fixedly connected with a second connecting tube. One end of the second connecting tube away from the first gas-liquid separator is fixedly connected with a second gas-liquid separator. The upper end of the second gas-liquid separator is fixedly connected with a first connecting tube. The upper end of the first connecting tube is fixedly connected to one end of the first gas outlet pipe away from the transfer tube. The cooled gas is dehumidified twice by the first gas-liquid separator and the second gas-liquid separator, and the water droplets in the gas are filtered out.

[0008] As a further description of the above technical solution:

[0009] One side surface of the first gas-liquid separator close to the second turning tube is fixedly connected with a baffle. One side of the second gas-liquid separator close to the second connecting tube is fixedly connected with a baffle. The gas entering the first gas-liquid separator and the second gas-liquid separator is blocked by the baffle, so that the gas needs to bypass the lower end of the baffle to flow upward, and the water droplets in the gas will hit the baffle and thus fall.

[0010] As a further description of the above technical solution:

[0011] Three groups of umbrella plate separators are fixedly connected inside both the first gas-liquid separator and the second gas-liquid separator. And two groups of umbrella plate separators are arranged above the baffle, and one group of umbrella plate separators is arranged below the baffle. A number of through holes are arranged at the quarter points of the umbrella plate separators. The gas entering the first gas-liquid separator and the second gas-liquid separator moves upward after bypassing the baffle. The gas bypassing the baffle will flow upward, and the large water droplets in the gas will fall and hit the surface of the lower umbrella plate separator, breaking the large water droplets, so that the air and water droplets on the large water droplets are blocked by the umbrella plate separator. The air flows through the through holes on the two layers of umbrella plate separators to the upper ends of the first gas-liquid separator and the second gas-liquid separator. The small water droplets in the gas will condense into large water droplets on the inner side surface of the umbrella plate separator and fall to the lower ends of the first gas-liquid separator and the second gas-liquid separator.

[0033] Working principle: Since the refrigerant refrigeration part of the dry cooler is a completely disclosed technology, the structure of the refrigerant refrigeration part of this device is roughly described, and only the main structure representing the refrigerant refrigeration part is drawn. When in use, the high-temperature gas enters the inside of the pre-cooling tube 4 through the first intake pipe 7, and the gas that has completed the dry cooling process passes through the middle of the pre-cooling tube 4 through the first outlet pipe 8. The high-temperature gas flowing inside the pre-cooling tube 4 is absorbed by part of the heat by the low-temperature gas in the middle of the first outlet pipe 8, thereby pre-cooling the high-temperature gas. The pre-cooled gas enters the inside of the transfer tube 5 and passes through the funnel 12, so as to flow from the upper part to the lower part of the transfer tube 5. The funnel 12 can prevent the gas from flowing from the lower end of the transfer tube 5 to the upper end of the transfer tube 5. The gas enters the inside of the heat exchange tube 6 from the transfer tube 5. The refrigerant compressor 1 converts the refrigerant into high-temperature and high-pressure steam, and the condenser 2 converts the high-temperature and high-pressure gas discharged by the refrigerant into a liquid refrigerant. The refrigerant supply inside the heat exchanger 13 is controlled by the expansion valve 3. The high-temperature gas is absorbed by the refrigerant inside the heat exchanger 13, so that the water vapor in the gas is liquefied, thereby achieving the dry cooling effect. The refrigerant circulates among the heat exchanger 13, the refrigerant compressor 1, and the condenser 2. The cooled gas enters the inside of the first gas-liquid separator 9 through the first turning tube 14 and the second turning tube 21. The gas entering the inside of the first gas-liquid separator 9 and the second gas-liquid separator 10 moves upward after bypassing the baffle 24. The gas bypassing the baffle 24 will flow upward, and the large water droplets in the gas will fall and hit the surface of the umbrella plate separator 25 at the lower end, breaking the large water droplets, so that the air and water droplets on the large water droplets are blocked by the umbrella plate separator 25. The air passes through the through holes on the two layers of umbrella plate separators 25 and flows to the upper ends of the first gas-liquid separator 9 and the second gas-liquid separator 10. The small water droplets in the gas will condense into large water droplets on the inner side surface of the umbrella plate separator 25 and fall to the lower ends of the first gas-liquid separator 9 and the second gas-liquid separator 10. When the gas passes through the foam-breaking net 22, the three groups of foam-breaking nets 22 will condense the small water droplets in the gas into large water droplets, so as to fall. After the gas is cooled and dried, it enters the first outlet pipe 8 from the first connecting pipe 11 and is thus collected.
