Abstract
The invention discloses an esterification reaction device for preparing plasticizers. The esterification reaction device comprises a casing, wherein material pipelines are respectively arranged on both sides in the casing, a mixing reactor is arranged at the bottom in the casing, all the material pipelines extend in the mixing reactor, a heating coil is arranged in a region between the material pipelines and the mixing reactor in the casing, and a discharge opening which is communicated with the outside of the casing is formed in the bottom of the mixing reactor. According to the esterification reaction device disclosed by the invention, the heating coil is arranged, so that the flow speed of reaction materials entering the mixing reactor is raised, which is favorable for the rapid sufficient bonding of two materials; besides, an air pump is arranged, so that the bonding speed of the materials is accelerated, and further the time for an esterification reaction is shortened; the reaction is prevented from being performed towards the opposite direction, and the production rate of plasticizers can be increased; the whole esterification reaction device is scientific and reasonable in design, occupies a small area, and is convenient to operate.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of esterification reaction equipment for the preparation of plasticizer.
Background technology
Plasticizer is the industrial macromolecular material auxiliary agent be widely used, and adds this material in plastic processing, and its pliability can be made to strengthen, easily process, this product is widely used in industrial sector.Plasticizer ideal at present adopts benzoic acid and glycerine to obtain new environment-friendlyplasticizer plasticizer to carry out esterification.Because the esterification of benzoic acid and glycerine exists certain invertibity, therefore the best way is that the while of adding benzoic acid, glycerine on limit, limit is reacted, so just require that benzoic acid, glycerine preferably can be heated by Quick uniform when entering reactor, thus make both by after mutual mixing, can esterification fast, enhance productivity.
Summary of the invention
Goal of the invention: the object of the invention is to for the deficiencies in the prior art, provides a kind of esterification reaction equipment for the preparation of plasticizer.
Technical scheme: in order to achieve the above object, the present invention specifically adopts following methods to realize: a kind of esterification reaction equipment for the preparation of plasticizer, it comprises housing, in housing, both sides are provided with material pipe, housing inner bottom part is provided with mixing reactor, described material pipe all passes in mixing reactor, is provided with heater coil in the region in housing between material pipe and mixing reactor, is provided with towards the discharging opening outside housing bottom mixing reactor.
Wherein, described material pipe top connects air pump by pipeline, accelerates to promote material enter mixing reactor by air pump pressurization.
Wherein, bottom described mixing reactor, be provided with one group of aeration tube, improve the speed of material reaction in mixing reactor further.
Wherein, outside described heater coil, be filled with one layer of heat preservation asbestos, prevent that heating-up temperature is too high to be impacted material pipe and mixing reactor.
Wherein, the material pipe tube wall in described mixing reactor has one group of through hole, accelerate material and enter reactor.
Wherein, described material pipe all adopts 316 stainless steel materials to make.
Beneficial effect of the present invention:
The present invention is compared with conventional art, improve flow velocity when reaction mass enters mixing reactor by built-in heater coil, be conducive to fully combining fast of two kinds of materials, simultaneously, introduce this device of air pump and serve again the speed again accelerated material and combine, the time of the esterification of this product can be shortened further, can prevent reaction from carrying out towards reverse direction, effectively improve the productive rate of plasticizer, whole equipment de-sign is scientific and reasonable, especially floor space is much less than legacy equipment, facilitates the operation of employee.
