specific Embodiment 1

[0029] figure 1 Constitute the process flow diagram of this specific embodiment.

[0030] Special equipment for the separation method of flocs in the production of terpene resins,

[0031] It is mainly composed of three containers: vacuum collection tank 1, moisture separator 2, and demulsification separator 3 according to certain spatial positions; the spatial positions of the three containers are: vacuum collection tank 1, moisture separator 2, demulsification separator The separators 3 are placed sequentially from top to bottom, the bottom of the vacuum collection tank 1 is higher than the top of the water separator 2, and the bottom of the water separator 2 is higher than the top of the demulsification separator 3 to ensure that the previous container The material inside can naturally flow to the next container by its own gravity.

[0032] Wherein, the vacuum collection tank 1 has a suction pipe 1-1 with a filter suction head at the entrance, and the bottom has a dischar...

Abstract

The invention discloses a method and special equipment for separating flocs in the production of terpene resins. The flocs are collected by a vacuum collection tank (1), and after part of the water is removed by a water separator (2), they enter a demulsification separator. (3) Separation. The separation principle is mainly to use demulsifier and neutralizer to separate flocs into fat liquid phase and water phase, and the fat liquid phase is collected and recycled. In the separation method of the present invention, the process route is simple and easy, the raw materials of the demulsifier and neutralizer used are cheap and easy to obtain, the separation cost is low, and the efficiency is high; it is non-toxic, harmless, and pollution-free, and the fat liquid is recycled and used to reduce waste It is a treasure, which improves the product yield and reduces the production cost.

Description

technical field [0001] The invention relates to a method for separating flocs, in particular to a method and special equipment for separating flocs in terpene resin production. It is suitable for separating the flocs formed by emulsification during the hydrolysis process of terpene resin industrial production. The invention belongs to the technical field of organic matter separation. Background technique [0002] Terpene resin (C 10 h 16 ) n , also known as polyterpene, mainly uses anhydrous aluminum trichloride as catalyst, toluene or xylene as solvent, and α-pinene and β-pinene in turpentine oil or tall oil as polymerized monomers in industry. It is obtained by cationic polymerization in a reactor at a low temperature. Terpene resins are a series of linear polymers from liquid to solid. After the polymerization reaction, in order to obtain pure terpene resin, the mixture in the reactor (mainly including terpene resin, low-polymerization degree compounds, a small amou...
