Description

Technical Field

[0001] This utility model relates to the field of activated carbon adsorption technology, specifically to a water-saving continuous cooling device for activated carbon. Background Technology

[0002] The cooling process after high-temperature desorption of activated carbon is a crucial step in its application in refrigeration or air purification cycles. During desorption, the activated carbon is heated to a high temperature by an external heat source, causing the adsorbed moisture or volatile organic compounds in its internal pores to desorb, restoring the activated carbon to a dry state and its adsorption capacity. After desorption, the adsorption bed temperature is extremely high, necessitating effective cooling. This cooling process is not for directly generating cooling capacity, but rather to prepare for the subsequent adsorption-refrigeration cycle. Because the adsorption capacity of activated carbon decreases sharply with increasing temperature, high-temperature activated carbon can hardly effectively adsorb vapors. Only after the adsorption bed temperature is lowered to near ambient temperature through natural convection, forced air cooling, or water cooling can its powerful adsorption performance be restored. The cooled, highly activated carbon bed regains its ability to create a low-pressure environment: when the system is connected to the evaporator, the low-temperature activated carbon vigorously adsorbs the vapors generated by the refrigerant evaporation in the evaporator, thus maintaining continuous evaporation, absorbing a large amount of heat, and ultimately achieving a cooling effect. Therefore, the efficiency of cooling after desorption directly determines the start-up speed and efficiency of the new round of adsorption-refrigeration, and is key to maintaining the entire system cycle.

[0003] Existing activated carbon cooling equipment, in order to cool activated carbon down as quickly as possible, results in a high water content in the activated carbon after water cooling, and cannot effectively recover and utilize the water vapor generated during cooling, causing a waste of water resources. Therefore, a water-saving continuous activated carbon cooling equipment is needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a water-saving continuous cooling device for activated carbon.

[0005] The technical solution of this utility model is: a water-saving continuous cooling device for activated carbon, including a water filter tank, a spiral conveying rod rotatably connected inside the water filter tank, a conveying motor for driving the spiral conveying rod to rotate fixedly connected to the left end of the water filter tank, a feeding port connected to the upper left side of the water filter tank, a cooling chamber wrapped around the outside of the water filter tank, the bottom of the water filter tank and the inner bottom of the cooling chamber being fixedly connected by multiple support rods, multiple spray heads being provided on the top of the cooling chamber, the multiple spray heads being connected to a water tank through a water supply pipe, and a water pump for supplying water to the water supply pipe being fixed inside the water tank.

[0006] Furthermore, a filter screen is fixedly connected to the bottom of the cooling chamber, a sedimentation tank is provided in the middle of the filter screen, a spiral cleaning rod is rotatably connected in the sedimentation tank, a cleaning motor for driving the spiral cleaning rod to rotate is fixedly connected to the left end of the cooling chamber, and a water collection tank is provided below the filter screen and fixedly connected to the outer wall of the bottom of the cooling chamber.

[0007] Note: Fine activated carbon sediment that seeps from the filter tank is collected through the sedimentation tank and then removed by the spiral cleaning rod.

[0008] Furthermore, a return pump is fixedly connected inside the water collection tank, and the outlet of the return pump is connected to a return pipe, the end of which is connected to the water tank.

[0009] Explanation: The water in the collection tank is returned to the water tank by the return pump for recycling, thus achieving the purpose of water conservation.

[0010] Furthermore, an exhaust fan connected to the interior of the cooling chamber is fixedly connected to the top right side of the cooling chamber, and the exhaust outlet of the exhaust fan is connected to an exhaust pipe. An air inlet pipe is fixedly connected to the top left side of the condensation chamber.

[0011] Explanation: The front section of the cooling chamber uses water cooling to quickly cool the high-temperature activated carbon, while the rear section uses an exhaust fan to increase the evaporation of water from the surface of the activated carbon, thereby further cooling the activated carbon.

[0012] Furthermore, the water tank is surrounded by a condensation chamber, and a water pump is provided at the bottom of the condensation chamber. The outlet of the water pump is connected to a condensation pipe, the end of which is connected to the inside of the water tank. The middle part of the condensation chamber is connected to the exhaust pipe, and an air outlet pipe is fixedly connected to the top left side of the condensation chamber. The end of the air outlet pipe is connected to the side wall of the air inlet pipe.

[0013] Explanation: High-temperature water vapor enters the condensation chamber and exchanges heat with the water in the water tank to form condensate. The condensate is pumped back to the water tank for recycling by a water suction pump. Water vapor that does not condense in time re-enters through the air inlet pipe for circulation.

[0014] The beneficial effects of this utility model are: The front section of the cooling chamber of this utility model uses water cooling, while the rear section enhances the airflow rate, thereby enhancing the evaporation of water molecules on the surface of the activated carbon and achieving the purpose of cooling the activated carbon. This reduces the water content of the discharged activated carbon. The water collection tank recycles the cooling water, and the water vapor can also be condensed and recovered for reuse, so as to achieve maximum water conservation. Attached Figure Description

[0022] The water in the collection tank 35 is returned to the water tank 6 by the return pump 351 for recycling, thus achieving the purpose of water conservation.

[0023] Example 2: The difference between this embodiment and embodiment 1 is that, in this embodiment, an exhaust fan 36 that communicates with the interior of the cooling chamber 3 is fixedly connected to the top right side of the cooling chamber 3, and the exhaust port of the exhaust fan 36 is connected to the exhaust pipe 37.

[0024] Compared to Example 1, in this embodiment, the front section of the cooling chamber 3 uses water cooling to quickly cool the high-temperature activated carbon, while the rear section uses the exhaust fan 36 to enhance the evaporation of water on the surface of the activated carbon, thereby further cooling the activated carbon.

[0025] Example 3: The difference between this embodiment and embodiment 2 is that, in this embodiment, the water tank 6 is surrounded by a condensation chamber 7, and a water pump 71 is provided at the bottom of the condensation chamber 7. The outlet of the water pump 71 is connected to a condensation pipe 72, and the end of the condensation pipe 72 is connected to the inside of the water tank 6.

Tiny activated carbon particles that leak down from the filter tank 1 with the water flow enter the sedimentation tank 32 and are discharged through the spiral mud cleaning rod 33. S3. When the activated carbon particles with water droplets on their surface move to the rear section of the water filter tank 1, the air flow rate in the cooling chamber 3 is increased by the exhaust fan 36, thereby increasing the evaporation of water on the surface of the activated carbon and further cooling the activated carbon.
