Description

Technical Field

[0001] The utility model relates to the technical field of ethylene tar granulation equipment, in particular to an ethylene tar granulation device. Background Art

[0002] Ethylene tar is a product formed by the combination of the product of the cracking of the initial raw materials in a high temperature environment and the reactants during the ethylene production process. Most of its components are heavy aromatic fraction oil. In industrial production, ethylene tar is often prepared into ethylene tar resin for use in multiple fields. Ethylene tar resin is made from the ethylene tar recombinant component reserved after the extraction of aromatic oil and industrial naphthalene from ethylene tar. It is added to the stripping tower kettle, and then an initiator is added. The stripping tower kettle is heated and reacted at normal pressure. The prepared ethylene tar resin needs to be granulated using a granulator for easy packaging and transportation.

[0003] The existing granulator has poor cooling effect, and during the production process, ethylene tar resin is easily left on the conveyor belt. If the ethylene tar resin left on the conveyor belt is not cleaned, the residue will adhere to the newly granulated ethylene tar particles, and the produced particles will have burrs and other defects.

[0004] For example, an ethylene tar granulation device disclosed in Chinese patent publication number CN213348772U can cool down the inside of the granulator by using single water cooling, single air cooling or simultaneous air cooling and water cooling, thereby enhancing the cooling effect and improving work efficiency; by arranging a scraper and a cleaning roller, the residue on the conveyor belt can be cleaned to avoid the residue from adhering and affecting the product quality; by arranging an oiling mechanism, the demoulding oil forms a thin film on the conveyor belt, the material is not easy to adhere to the conveyor belt, and is more easily scraped off by the unloading mechanism, and no dust is generated during the scraping process, which not only protects the ethylene tar resin particles, but also reduces the loss of the conveyor belt and the unloading mechanism; by arranging a flue gas treatment device, the flue gas generated in the granulation process can be recovered and treated, achieving zero emission to the environment, achieving clean production, and using the principle of like dissolving like to treat the flue gas, with low cost and low energy consumption; by arranging a filter, the impurities of the ethylene tar resin can be filtered to improve the quality of the granulation.

[0005] The existing technology has the following problems:

[0006] In the actual process of ethylene tar granulation, ethylene tar needs to be strongly stirred before being transported on the conveyor belt. However, ethylene tar is easily adhered to the inside of the pipe due to its own characteristics. Long-term storage will cause raw material pollution to the subsequent granulation production.
