Description

Technical Field

[0001] The invention relates to the technical field of storage tanks, in particular to a large-volume multi-cavity storage tank with an anti-coking heating system and a turbulence system. Background Art

[0002] 1: Some enterprises need to store new materials during technological transformation, so they need to add new storage tanks. At the same time, the spacing requirements of adjacent storage tanks must be met as required by the regulations. However, due to the lack of land available in the surrounding area, it is impossible to plan the layout space for new storage tanks, which seriously restricts the improvement and development of the enterprise's technological process. Therefore, the design of a storage tank with a small footprint and a large integral cavity that can store multiple materials can resolve similar problems in the development of an enterprise.

[0003] 2: Currently, most of the chamber storage tanks are small-volume storage tanks, and the partitions that separate the chambers are all straight partitions or straight partitions with reinforcing ribs. As the volume of the equipment increases, the diameter and height of the equipment also increase, resulting in excessive height differences of materials in each chamber. The liquid column pressure causes the chamber partitions to deform, posing a safety hazard. This requires more reinforcing structures or profiles to strengthen the chamber partitions, resulting in a large waste of materials and increasing the manufacturing cost of the equipment. Therefore, it is necessary to design a simple structure to enhance the ability of the chamber partition to resist liquid level differences, while saving materials and reducing manufacturing costs.

[0004] 3: When storing materials in many storage tanks, in order to prevent the materials from being overcooled and crystallized and affecting the loading and unloading of materials, steam heating coils are often designed at the bottom of the storage tanks to heat the materials. Since the temperature of the existing steam source on site is high and the temperature is not easy to control manually, the heating coils are in contact with the materials in the storage tanks for a long time, and coking occurs on the surface of the coils, which corrodes and damages the coils and reduces the service life of the coils. Therefore, it is necessary to design an external heating system that can heat the bottom of the storage tank evenly and prevent the higher temperature coils from directly contacting the materials. This can extend the life of the heating system and prevent coking due to excessively high heating temperatures in the tanks.

[0005] 4: Since the material is stored in the storage tank for a long time, the heavy components in the material components sink and the light components float, resulting in stratification of the material, and it is impossible to discharge a uniform mixed material during unloading. Summary of the invention

[0006] In order to solve the technical problems existing in the background technology, the present invention provides a large-volume multi-cavity storage tank with an anti-coking heating system and a turbulence system, each cavity of which can be used independently, one tank has multiple uses, and an independent heating device is provided, which has a better heat transfer effect, and a nozzle turbulence device and multi-point discharge branch pipelines in the tank are provided to prevent the material in the tank from stratifying and being unable to discharge homogeneous materials.
