Description
Technical field
The utility model relates to a kind of reactor temperature control system for emulsion polymerization, belongs to technical field of chemical.
Background technology
during temperature, affect one of key factor of polyreaction how, temperature is too low, and polymerization rate reduces, and has the latex particle decreased number of polymerization activity, and the reaction time is long and the not high reaction of monomer conversion is incomplete.Excess Temperature, restive, have sudden and violent poly-phenomenon easily to cause danger, and polymerization rate increase, latex particle number increases, and particle diameter reduces, and stability of emulsion reduces, there is the danger of latex livering in reactor, so will, according to formula requirement, strictly control temperature when operation polyreaction.In practical operation, volume with respect to reactor, as the volume of controlling the chuck of temperature of reaction, want little a lot, when temperature dial plate shows when too high, too late toward adding chilled water in chuck, but the too early overlong time that passes into chilled water or pass into chilled water can cause not reaching again temperature of reaction, therefore, need to develop a kind of reactor temperature control system that can accurately control temperature of reaction.
Summary of the invention
When the purpose of this utility model is to solve existing reactor for emulsion polymerization, temperature is difficult to the deficiency of effectively controlling, a kind of reactor control system for emulsion polymerization is provided, this reactor control system can regulate the temperature of reaction system in reactor efficiently, improves speed and the efficiency of emulsion recombination reaction.
The utility model solves the technical scheme that its technical matters adopts:
A kind of reactor temperature control system for emulsion polymerization, the reactor that comprises jacketed, the bottom of chuck is provided with water inlet, the both sides, top of chuck are respectively equipped with water delivering orifice, also comprise control module, temperature sensor, operation valve, make-up pump and circulating water pool, described temperature sensor is fixed at the side of reactor, the input end of described make-up pump is communicated with circulating water pool, water supply delivery side of pump is communicated with the import of operation valve, the outlet of operation valve is communicated with water inlet, described temperature sensor, operation valve is connected with the control port of control module by data line respectively with make-up pump.According to the optimal reaction temperature of emulsion polymerization, in control module, set in advance, temperature sensor is experienced the temperature of reaction system in reactor and output signal is sent to control module, control module is analyzed the output signal receiving, when temperature is during higher than default optimal reaction temperature, control module controls operation valve and make-up pump is opened, and in reacting kettle jacketing, supplies with chilled water; By temperature, during lower than default optimal reaction temperature, control module is controlled operation valve and make-up pump cuts out, and stops supplying with chilled water; The utility model is simple in structure, and temperature control effect is good, has avoided the violent rising of temperature of reaction of emulsion polymerization or has reduced the defect that affects emulsion polymerization speed and efficiency.
As preferably, described temperature sensor adopts thermopair class.Thermopair class arrangement of temperature sensor is simple, easy to use, and cost is low.
As preferably, described operation valve is pneumatic control valve.
As preferably, described control module is PLC control module.
As preferably
,described temperature sensor is fixed at the side of reactor from the position of the bottom 50 ~ 80cm of reactor.Under the technical program, temperature sensor can the most accurate reaction response still in the temperature of emulsion polymerization.
The beneficial effects of the utility model are: automaticity is high, can control accurately the temperature of emulsion polymerization, use after the utility model, the temperature difference of emulsion polymerization can be controlled in less interval on the one hand, speed and the efficiency of emulsion polymerization are improved; On the other hand, can improve the work efficiency of make-up pump, save the energy consumption of make-up pump, reduce production costs.
