Description

Technical Field

[0001] The utility model relates to the technical field of catalytic cracking recovery tanks, in particular to a catalytic cracking recovery tank. Background Art

[0002] Catalytic cracking is an important chemical reaction process that mainly occurs under the action of catalysts. It involves high-temperature cracking of petroleum hydrocarbons or other organic substances to produce low-carbon olefins such as ethylene, propylene, butene, and light aromatics at the same time. In this process, the presence of catalysts can reduce the reaction temperature and increase the yield of low-carbon olefins and light aromatics, thereby increasing the flexibility of cracking product distribution. The catalytic cracking recovery tank is a storage tank-type container for recovering the medium during the catalytic cracking process.

[0003] The existing catalytic cracking recovery tank has a single function. After recovery, it can only serve as a temporary storage, which brings inconvenience to users. Based on these problems, Chinese patent CN217614656U discloses a multifunctional catalytic cracking recovery tank. The catalytic cracking recovery tank body is divided into two layers: an outer jacket layer and an internal storage tank. On the basis of storage and recovery in the internal storage tank, heat conduction can be carried out by relying on the heat conduction layers of the outer walls on both sides. For high-temperature media, it can be conducted to the outer jacket layer through the heat conduction layer. The inner circulation water pipe in the outer jacket layer is connected to the external pipe port, so that cold water medium circulates inside it, and the interior is cooled by heat conduction. For low-temperature media, hot water medium can be externally connected and transported to the inner circulation water pipe, and heat is conducted inwardly through the heat conduction layer to increase the temperature of the internal medium to achieve the heating effect. Through the above structure, the recovery tank can have the effects of cooling and heating, and can be indirectly heated and cooled without contacting the medium, so that the internal recovery medium is not easily contaminated, thereby improving the functionality and practicality of the recovery tank.

[0004] The catalytic cracking recovery tank is provided with a heating mechanism and a water-cooling mechanism on the outside. The normal operation of the heating mechanism and the water-cooling mechanism can improve the functionality and practicality of the recovery tank. However, there is a lack of protective devices on the outside of the heating mechanism and the water-cooling mechanism. Therefore, external collisions or tipping of the recovery tank can easily cause damage to the heating mechanism or the water-cooling mechanism, which not only affects the storage effect of the recovery tank, but also reduces the service life of the recovery tank.
