Description
Technical field
The utility model belongs to the Chemicals production field, mainly is the reaction unit that a kind of normal temperature prepares polycarboxylic acid super-plasticizer.
Background technology
In polyreaction, Raolical polymerizable has polymer moment formation, and the relative molecular weight of product does not change in time; Reaction chain carries out, transformation efficiency in time prolongation and characteristics such as increase.Yet in radical polymerization, temperature controlling is huge to the influence of product, and the heat of polymerization that discharges the chainpropagation stage especially effectively is the key of radical polymerization success.Therefore design and the good polymerizing reactor of manufacturing temperature control become the industrialized most important thing under this class reaction normal temperature of realization.
Heat pipe is a kind of novel, heat conducting element efficiently, and its relies on self internal working medium phase transformation to carry out heat conduction, mainly is made up of metallic seal pipe, wick and vapour passage 3 parts.Hot pipe technique is the heat transfer element of a kind of being called " heat pipe " of the G.M.Grover invention of U.S. LosAlamos National Laboratory in 1963, it has made full use of the Rapid Thermal hereditary property of heat-conduction principle and refrigeration filling, be delivered to rapidly outside the thermal source through the heat of heat pipe with thermal objects, its capacity of heat transmission surpasses the capacity of heat transmission of any known metal.
Hot pipe technique being applied in the manufacturing of reactor also is one of hot fields of Recent study.And this technology is applied in the Raolical polymerizable, it is big to solve this type of exothermic heat of reaction amount effectively, the uppity shortcoming of temperature of reaction.
The utility model content
Technical problem to be solved in the utility model provides the reaction unit that a kind of normal temperature prepares polycarboxylic acid super-plasticizer, and it utilizes hot pipe technique to control the Raolical polymerizable temperature effectively, realizes the normal temperature suitability for industrialized production of this type of reaction.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of normal temperature prepares the reaction unit of polycarboxylic acid super-plasticizer, include polymerization reaction kettle, dog-house is arranged at the polymerization reaction kettle top, discharge port is arranged at the bottom, be rotatablely equipped with the heat pipe-type stir shaft in the described polymerization reaction kettle, polymerization reaction kettle is stretched out in heat pipe-type stir shaft upper end, and there is stirring rake the lower end, on the part that described stir shaft stretches out radiating fin is arranged, heat absorption fin and radiating fin are arranged on the stir shaft in the polymerization reaction kettle; The circulation fluid cooling tank is arranged on the outer wall of described polymerization reaction kettle, have water-in, water outlet on the cooling tank, there is the bending in the cooling tank of wick type heat pipe to extend in the polymerization reaction kettle, heat absorption fin and radiating fin are arranged on the tube wall of described wick type heat pipe; The electric heating element assisted heating device is arranged at described polymerization reaction kettle bottom; A plurality of upflow tubes are arranged on the sidewall of described polymerization reaction kettle.
Described heat pipe-type stir shaft adopts gravity type heat pipe; Described heat pipe-type stir shaft is connected with motor.
Hot working fluid is a water in the utility model, and shell is a titanium steel composite material.
The utility model combines the advantage of gravity type heat pipe and wick type heat pipe effectively, realized in the reaction inside and outside the refrigerative effect simultaneously of heating simultaneously, reached the even heating and the cooling purpose of reaction.Simultaneously, because the workability of wick type heat pipe is a reversible, thereby, can utilize heated cooling fluid in the polyreaction, when continuing to be heated to certain temperature, come initiation reaction as the heating fluid that reacts.
When carrying out Raolical polymerizable, at first, reaction mass enters in the reactor by feeding unit, circulation fluid with preheating under agitation condition feeds the circulation fluid cooling tank from upper port, by the lower port fluid, simultaneously, open the assisted heating device of reactor bottom, the heated polymerizable reaction, the tape test device is measured reaction when having begun to carry out, and changes circulation fluid immediately, be about to cold cycle liquid from lower port by the circulation fluid cooling tank, flow out from upper port, thereby play the effect of whole temperature control.
Wherein the gravity type heat pipe mode of operation is: when needs heated, by wick type heat pipe and heating member heating, through stirring, heat was passed to the heat pipe heating zone, discharges at condensation segment vertically, realizes the purpose of whole heating in the chuck; In the chainpropagation stage, material is emitted violent reaction heat, the aggravation of heat pipe condenser section in-tube condensation, make the interior vapor temperature of pipe descend, the temperature of heating zone also descends thereupon, fast reaction heat is taken away thus, the conditioned reaction temperature, evenly the axial temperature field makes it to be controlled on the optimum response curve temperature, guarantees that the success of polyreaction is carried out.
Wick type heat pipe mode of operation is: when needs heat, condensation segment annular water tank in change hot water into, use as " heating zone " this moment, heat has been passed to heating zone, reaches the purpose of reaction heating, simultaneously the heating of reactor bottom, stir simultaneously, reaction integral body is heated evenly.By following the tracks of reaction, in case chain initiation success, change the water in the tank immediately, it is changed to low-temperature cooling water, in the reactor, because chainpropagation begins, material discharges a large amount of heat at this moment, heat pipe condenser section condensation aggravation, under the effect of capillary force, return condensed section of working medium makes the interior vapor temperature of pipe descend, the temperature of heating zone also descends thereupon, fast reaction heat is taken away conditioned reaction temperature, evenly radial temperature field thus, make it to be controlled on the optimum response curve temperature, guaranteed that further the success of polyreaction is carried out.
The utility model utilizes the temperature regulating device of hot pipe technique as Raolical polymerizable, compared with prior art has following advantage:
The heat transfer efficiency height utilizes the phase transformation of working medium to play heat-transfer medium, and the heat of the material absorbing of unit mass can reach very big value; The reduction of huge amount the usage quantity of water coolant, when reducing cost, reached the purpose of environmental protection; The heat that utilizes reaction to discharge, the reaction of heating next batch, success reduced the cost of reaction; Realized suitability for industrialized production under the normal temperature of radical polymerization.Because heat pipe has good isothermal and thermostatic characteristics, therefore in polymeric reaction temperature control, have more superiority, and each assembly element is separate, thereby is easy to operations such as dismounting, cleaning owing to be assembly element.
