Technical Field

The utility model belongs to the technical field of petroleum resin production, more specifically say, relate to a C5 petroleum resin production is with taking off washing processing apparatus that urges.

Background

The C5 petroleum resin is also called carbon five resin and aliphatic hydrocarbon resin, and is a thermoplastic resin mainly made up by using carbon five petroleum resin fraction as by-product of petroleum cracking as raw material and making it pass through the process of catalyst polymerization. The C5 petroleum resin has the advantages of low price, good miscibility, low melting point, water resistance, ethanol resistance, chemicals resistance and the like, so the C5 petroleum resin is widely applied to various industries and fields such as rubber, adhesives, coatings, papermaking, printing ink and the like, different industries and fields have different requirements on the physical and chemical properties of the C5 petroleum resin, and the chromaticity, the softening point and the compatibility of the C5 petroleum resin are the most important technical indexes in the physical and chemical properties. At present, the production method of the C5 petroleum resin mainly comprises the following steps: the method comprises the steps of raw material pretreatment and configuration, catalytic polymerization, deactivation and washing, flash evaporation and desolventization, vacuum stripping, granulation and solvent recovery and separation. Most of the related patents at home and abroad make some improvements on the production process in the aspects of raw material treatment and configuration, catalyst configuration, catalytic polymerization and the like so as to achieve the purpose of improving the quality of C5 petroleum resin.

However, the removal of the catalyst is a key link for synthesizing high-quality C5 petroleum resin, and since unreacted catalyst may remain in a polymerization solution obtained after the polymerization reaction, if the catalyst is not removed, the hue of the C5 petroleum resin obtained by production is deteriorated, the transparency is reduced, the ash content is ultrahigh, the molecular weight distribution of the C5 petroleum resin is also affected, and the influence on the performance of the resin is very obvious. According to the different selected process and catalyst, the present method for removing catalyst at home and abroad generally adopts three methods of water washing, alcohol washing and clay-calcium hydroxide dry cleaning. For the water washing method, a water washing stirring kettle is mainly adopted for water washing removal, and then the catalyst removal is carried out through a first-stage, a second-stage and a third-stage water washing settling tanks respectively. However, because the power of the existing water-washing stirring kettle device is too low, hot water and polymerization liquid cannot be fully mixed, so that the water washing is not thorough and the effect is poor, when the water-washing stirring kettle device further enters a subsequent water-washing settling tank for water-washing settling, the content of chloride ions in the polymerization liquid is high, and the polymerization liquid is easily brought into a subsequent system to cause pipeline corrosion and leakage. Through retrieval, the Chinese patent application number: 201520574795.7, filing date: in 2015, 07, 31 days, the invention is named as: a deactivation and removal system for C5 petroleum resin catalyst, in the application, a liquid outlet pipe of a polymerization liquid extraction pump is connected with an auxiliary agent supply pipe and a hot water supply pipe and then is converged into one path, and is connected with a feed inlet at the bottom of a water washing stirring kettle; a discharge hole at the top of the washing stirring kettle is connected with a feed inlet of the primary washing tank through a pipeline; a liquid outlet pipe at the top of the first-stage washing tank is connected with a hot water supply pipe and then is converged into one path, and the one path is connected with a feed inlet of the second-stage washing tank through a first mixer; the liquid outlet pipe at the top of the second-stage washing tank is connected with the hot water supply pipe and the ammonia water supply pipe and then is converged into one path, and the other path is connected with the third-stage washing tank through the second mixer. This application is through between one-level washing jar and second grade washing jar to and add the blender respectively between second grade washing jar and the tertiary washing jar, thereby can improve polymerization liquid and hydrothermal mixing uniformity to a certain extent, and then improve washing effect, but, in the actual production process, the phenomenon of jam easily appears in above-mentioned blender, thereby leads to washing unit pressure to rise, influences the stability of water washing system.
