Problems solved by technology

[0005] The device for industrial production of button-shaped petroleum resin has improved compared with the production of block petroleum resin, but it still uses a conveyor belt and requires a large installation site; the mechanical structure is similar, and they are all relatively complicated. Once condensation occurs in the machine during operation The problem is that it is very difficult to troubleshoot; the resulting product is button-shaped, and the particle size cannot be adjusted according to customer requirements; the production capacity of the equipment is small, and it is difficult to adjust the output according to production needs; the fluidity of the button-shaped petroleum resin is still not good enough. Many usage procedures are limited

Embodiment 1

[0024] The refined liquid C5 petroleum resin enters the nozzle from the silo and sprays downward. When spraying out, the nozzle is in the vibration movement driven by the vibration mechanism. The vibration frequency is 200 times per second and the amplitude is 3mm. Droplets become spherical droplets, and exchange heat with the rising inert gas in the prilling tower, and condense into spherical solid particles with an average particle diameter of 3 mm; the spherical solid particles fall into the fluidized bed at the bottom of the prilling tower for further cooling, Leave the prilling tower and enter the packaging process. The fluidization drive of the fluidized bed at the bottom of the prilling tower comes from the inert gas flowing upward from the bottom of the tower. The inert gas leaving the fluidized bed continues to move upwards in the prilling tower and interacts with the downward petroleum resin particles. Heat exchange, leaving the prilling tower from the top of the tow...

Embodiment 2

[0026] The refined liquid C5 petroleum resin enters the nozzle from the silo and sprays downward. When spraying out, the nozzle is in the rotating motion driven by the rotating mechanism at a speed of 20 rpm. The petroleum resin leaving the nozzle becomes spherical droplets driven by the movement of the nozzle. , and conduct heat exchange with the rising inert gas in the prilling tower, and condense into spherical solid particles with an average particle diameter of 1.5 mm; the spherical solid particles fall into the fluidized bed at the bottom of the prilling tower for further cooling, and leave the prilling tower to enter Packaging process. The fluidization drive of the fluidized bed at the bottom of the prilling tower comes from the inert gas flowing upward from the bottom of the tower. The inert gas leaving the fluidized bed continues to move upwards in the prilling tower and interacts with the downward petroleum resin particles. Heat exchange, leaving the prilling tower f...

Embodiment 3

[0028] The refined liquid C9 petroleum resin enters the nozzle from the silo and sprays downward. When spraying, the nozzle is in the vibration movement driven by the vibration mechanism. The vibration frequency is 500 times per second and the amplitude is 1mm. Droplets become spherical droplets, and exchange heat with the rising inert gas in the prilling tower, and condense into spherical solid particles with an average particle size of 1mm; the spherical solid particles fall into the fluidized bed at the bottom of the prilling tower for further cooling, Leave the prilling tower and enter the packaging process. The fluidization drive of the fluidized bed at the bottom of the prilling tower comes from the inert gas flowing upward from the bottom of the tower. The inert gas leaving the fluidized bed continues to move upwards in the prilling tower and interacts with the downward petroleum resin particles.

Abstract

The present invention relates to one kind of spherical petroleum resin particle and its production apparatus and process. The spherical petroleum resin particle in average size of 0.2-3 mm is produced in apparatus comprising a stock bin, a pelletizing tower connected through one pipeline to the stock bin, a nozzle in the top inside the pelletizing tower, a nozzle driving unit connected to the nozzle, one fluidizing cooler in the bottom of the pelletizing tower, a waste gas absorbing tower connected through one pipeline to the pelletizing tower, and a inert gas bin connected through one pipeline to the pelletizing tower. The spherical petroleum resin particle product has excellent flowability and high strength. The production apparatus has simple structure, and the production process is completely closed and environment friendly.

Description

technical field [0001] The invention relates to a petroleum resin spherical particle and its production equipment and manufacturing method, which is especially suitable for the particle production of C5 petroleum resin, C9 petroleum resin, and C5 and C9 copolymerized petroleum resin. Background technique [0002] Common petroleum resins in industry include C5 petroleum resin, C9 petroleum resin, C5 and C9 copolymerized petroleum resin. These petroleum resins are important functional synthetic resins because of their excellent solvent compatibility, acid and alkali resistance and Therefore, as important additives for organic materials, they have been more and more widely used in rubber, adhesives, coatings, inks, papermaking, etc. [0003] C5 petroleum resin and C9 petroleum resin are obtained from C5 and C9, which are by-products of the ethylene industry, respectively, through thermal polymerization or cold polymerization. The refined petroleum resin obtained after polymeri...
