Description
Technical field
The utility model relates to a kind of reactive system for unsaturated polyester resin, belongs to unsaturated polyester resin reaction unit field.
Background technology
Unsaturated polyester resin is generally the chain macromolecule compound with ester bond and unsaturated double-bond by the saturated dibasic alcohol of unsaturated dibasic acid or the unsaturated dibasic alcohol polycondensation of monounsaturated dicarboxylic acid.Usually, unsaturated polyester resin polycondensation is carried out at 190 ~ 220 DEG C, until reach the acid number (or viscosity) of expection, after unsaturated polyester resin polycondensation terminates, adds a certain amount of vinyl monomer while hot, is made into the liquid of thickness.
Reactor is the key equipment in unsaturated polyester resin polycondensation process, general reactor adopts clamp heating, when still volume gain, the ratio that still surface-area increases is less than volume gain ratio, so for unit volume, effective heating or cooling area have diminished, make the production cycle extend and restive.
In addition, the water that reaction process generates is by thermosetting water vapor, discharge from reactor top, more alcohol and acid can be mingled with in water vapor, prior art directly connects fractional column on reactor top, fractional column top connects vertical condenser and horizontal condenser successively, by the separation of fractional column, water vapor is isolated, alcohol and sour reuse, but adopt single fractional column, its inferior separating effect, still have alcohol and the acid loss of part, thus reduce the yield of unsaturated polyester resin, and increase the intractability of follow-up waste water.
Utility model content
The deficiency that the utility model exists for above-mentioned prior art, provides a kind of reactive system for unsaturated polyester resin.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of reactive system for unsaturated polyester resin, its special character is, comprise reactor and alcohol acid-restoring plant, described reactor sidewall is chuck, coil pipe and agitator is provided with in reactor, be provided with stopple coupon in the side of reactor, above reactor, be provided with vision slit and inert gas tube; Described alcohol acid-restoring plant comprises acid recovery tower, alcohol recovery tower, horizontal condenser and tank, described acid recovery tower is all connected with the air outlet on reactor top with the import of alcohol recovery tower, described acid recovery tower and alcohol recovery tower are arranged in parallel, the top of described acid recovery tower and alcohol recovery tower is in series with a vertical (type) condenser respectively, be connected with the entrance of horizontal condenser after the outlet parallel connection of two vertical (type) condensers, the outlet of described horizontal condenser is connected with tank.
The beneficial effects of the utility model are: the utility model is provided with coil pipe in reactor, production cycle is controlled, the agitator be provided with in reactor is on the medullary ray of reactor, mixing of materials can be made even, whole temperature of charge is even, prevent local superheating, the vision slit be provided with can be used for workman and enters in pot to check pot wall erosion situation and internal unit fine status, still is provided with multiple stopple coupon, like this can regularly inspection by sampling, to determine level of response, economic benefit of enhancing productivity.By the acid recovery tower that is arranged in parallel and alcohol recovery tower, phase is separated through alcohol recovery tower before the reaction, the reaction later stage, acid and alcohol recovery were separated comparatively thorough, and efficiency of pcr product improves 1-2% through the separation of acid recovery tower, and follow-up wastewater treatment is easy, can not to environment.
On the basis of technique scheme, the utility model can also do following improvement.
Further, described agitator is connected under described coil pipe.
Further, described coil pipe stainless steel tube is made, and is arranged on reactor inwall in the shape of a spiral, upwards extends by Polycondensation Reactor and Esterification Reactor.
The beneficial effect of above-mentioned further scheme is adopted to be make between reactant and thermal medium, there is good heat exchange, such a construction increases working efficiency.
Further, described agitator is propeller type.
Adopt the beneficial effect of above-mentioned further scheme to be to make mixing of materials even, make whole temperature of charge even, prevent local superheating, and various reactant contacts with each other well, moisture is discharged fast, reaction is accelerated, improves working efficiency.
