[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

The protective shell 102 isolates the recovery tank 103 from external temperature, thereby achieving the effect of passive heat dissipation;

[0030] In one embodiment, Figure 3 , Figure 5 and Figure 7As shown, the cooling device includes a water inlet 201, which is connected to the inside of a cooling block 202. The middle of the cooling block 202 is fixedly connected to the port of the recovery tank 103. The right side of the cooling block 202 is in contact with the tank body of the recovery tank 103. The side of the cooling block 202 is fixedly connected to a plurality of water circulation components for water cooling the recovery tank 103 at the surface position of the recovery tank 103. The circulating water pump is connected through the water inlet 201. The circulating water pump inputs the refrigerant into the inside of the cooling block 202 through the water inlet 201. The cooling block 202 is in contact with the recovery tank 103. The refrigerant completes a heat exchange reaction in the recovery tank 103 in the cooling block 202, thereby reducing the temperature of the recovery tank 103 and providing a low-temperature storage environment for catalytic cracking.

[0031] In one embodiment, Figure 5 and Figure 7 As shown, the water circulation component includes a cooling pipe 203, one end of a plurality of cooling pipes 203 is fixedly connected to the side of the cooling block 202, the surface of the cooling pipe 203 is in contact with the recovery tank 103, the other end of the cooling pipe 203 is fixedly connected to the cooling ring 204, the cooling ring 204 is fixedly connected to the side of the recovery tank 103, the refrigerant enters the cooling pipe 203 through the cooling block 202, a plurality of cooling pipes 203 are in contact with the surface of the recovery tank 103 to reduce the heat of the recovery tank 103, the refrigerant in the cooling pipe 203 enters the cooling ring 204 to dissipate heat for the side end of the recovery tank 103, and the surface of the recovery tank 103 is evenly cooled;

[0032] In one embodiment, Figure 1 As shown, the drying mechanism includes a fan blade 304, which is arranged on the side of the recovery tank 103, and the side of the fan blade 304 is fixedly connected to three transmission shafts 302. The fan blade 304 is fixedly connected to the surface of the recovery tank 103 to drive the transmission shaft 302 to rotate. The surface of the recovery tank 103 is provided with a plurality of auxiliary dehumidifiers that cooperate with the transmission shaft 302 to dry the surface of the recovery tank 103. The transmission shaft 302 rotates to cool the side of the recovery tank 103. During long-term heat dissipation, the cooling ring 204 The refrigerant temperature at the bottom is higher than the refrigerant temperature at the water inlet 201, and the air cooling of the transmission shaft 302 is used to perform secondary heat dissipation for the cooling ring 204, thereby reducing the temperature of the heat accumulation end of the water cycle, making the temperature of the surface of the recovery tank 103 tend to be average, and maintaining the consistency of the storage temperature. The air flow rate between the protective shell 102 and the recovery tank 103 is increased by air cooling of the transmission shaft 302, and the condensed water generated due to the excessive temperature difference between the surface of the protective shell 102 and the recovery tank 103 is reduced, providing dry storage conditions for the catalytic cracking medium;

[0033] In one embodiment, Figure 3 , Figure 4 and Figure 6As shown, the driving member includes a rotating motor 301, a fixed end of the rotating motor 301 is fixedly connected to the side of the recovery tank 103, and an output end of the rotating motor 301 is fixedly connected to a transmission shaft 302, and the transmission shaft 302 provides power for the rotation of the fan blade 304, and the rotation of the fan blade 304 drives the transmission shaft 302 to rotate, and the rotation of the transmission shaft 302 provides air cooling and heat dissipation for the surface of the recovery tank 103;

[0034] In one embodiment, Figure 2 and Figure 6 As shown, the auxiliary dehumidifier includes a drying box 303, and a plurality of drying boxes 303 are fixedly connected to the surface of the recovery tank 103 at the side position of the cooling pipe 203. Calcium sulfate and calcium chloride are installed inside the recovery tank 103. The rotation of the transmission shaft 302 provides a strong air flow for the drying box 303. During the air flow, the air exchanges heat with the protective shell 102 and the surface of the recovery tank 103. The air circulation takes away the moisture generated by the temperature difference, and the calcium sulfate and calcium chloride installed inside the recovery tank 103 absorb the remaining moisture, thereby avoiding the generation of moisture on the surface of the recovery tank 103, avoiding the reduction of the activity of the catalytic cracking medium due to high humidity, and reducing the quality of the catalytic cracking medium;

[0035] The above embodiment discloses a catalytic cracking recovery device, wherein the catalytic cracking medium is stored in the recovery tank 103, and the protection shell 102 is used to shield the recovery tank 103 from direct light. The protection shell 102 isolates the recovery tank 103 from the external temperature. When the ambient temperature is higher than the optimal storage temperature, the circulating water pump is connected through the water inlet 201, and the circulating water pump inputs the refrigerant into the cooling block 202 through the water inlet 201. The cooling block 202 contacts the recovery tank 103, and the refrigerant completes a heat exchange reaction with the recovery tank 103 in the cooling block 202. The refrigerant enters the cooling pipe 203 through the cooling block 202, and a plurality of cooling pipes 203 contact the surface of the recovery tank 103 to heat the recovery tank 103. The refrigerant in the cooling pipe 203 enters the cooling ring 204 to heat the recovery tank. The side end of 103 performs heat dissipation to uniformly cool the surface of the recovery tank 103. During long-term heat dissipation, the temperature of the refrigerant in the cooling ring 204 is higher than the temperature of the refrigerant at the water inlet 201. The air cooling heat dissipation of the transmission shaft 302 is used to perform secondary heat dissipation for the cooling ring 204, thereby reducing the temperature of the heat accumulation end of the water circulation, making the surface temperature of the recovery tank 103 tend to be average, and maintaining the consistency of the storage temperature. The rotation of the transmission shaft 302 provides a strong air flow for the drying box 303. During the air flow, heat exchange is generated between the air and the protective shell 102 and the surface of the recovery tank 103. The air circulation takes away the moisture generated by the temperature difference, and the calcium sulfate and calcium chloride installed inside the recovery tank 103 absorb the remaining moisture, thereby avoiding the generation of moisture on the surface of the recovery tank 103 and avoiding the reduction of the activity of the catalytic cracking medium due to high humidity.
