Abstract
The utility model relates to a reaction kettle, in particular to a spray polymerization reaction kettle with sensing thermometers, mainly solving the technical problems of low production efficiency and poor quality of current reaction kettles caused in that system temperature is represented inaccurately, only single points at special sections of reaction kettles can be detected, actual temperatureat other sections can not be measured, and various parameters can not be set accurately. The spray polymerization reaction kettle with the sensing thermometers comprises a reaction kettle (1), a feeding pipe (2) is connected with the upper end of the reaction kettle, the lower end of the feeding pipe extends into the reaction kettle (1), and the top, the bottom and the middle of the reaction kettle (1) are respectively connected with the sensing thermometers (3) capable of measuring temperature inside the reaction kettle.
Description
Technical field
The utility model relates to a kind of reactor, especially relates to a kind of to having the isostructural improvement of spray polymerization reactor of sensing temperature meter.
Background technology
Conventional EO/PO polymerization reaction kettle temperature control point generally is chosen at liquid phase material and stops the position, and the single-point temperature control is adopted in promptly common still bottom.Device fabrication, technological procedure are compiled and edit simply, processing ease.Chinese patent discloses a kind of autoclave (Granted publication number: CN 201179441Y), it comprises a reaction under high pressure kettle, be respectively equipped with a described Pressure gauge, charge door, agitator and temperature sensor binding post on the upper surface of reaction under high pressure kettle, the middle part of the lower surface of reaction under high pressure kettle is provided with a described discharging opening, be coated with a polytetrafluoroethylene (PTFE) rete on the inwall of reaction under high pressure kettle, the thickness of polytetrafluoroethylene (PTFE) rete is 1～5mm.But it is inaccurate that this reactor exists the reactor system temperature to characterize, and can detect except position, reactor upper end, and the actual temperature at other position can't be understood, and therefore can not accurately set each parameter, causes production efficiency lower, second-rate.
The utility model content
The utility model technical issues that need to address provide a kind of spray polymerization reactor that has the sensing temperature meter, it mainly is to solve existing in prior technology reactor system temperature to characterize inaccurate, except reactor privileged sites single-point can detect, the actual temperature at other position can't be understood, therefore can not accurately set each parameter, cause lower, second-rate etc. the technical problem of production efficiency.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
The spray polymerization reactor that has the sensing temperature meter of the present utility model, comprise reactor, it is characterized in that described reactor upper end is connected with feed pipe, the feed pipe lower end is stretched in the reactor, but the top of reactor, bottom and middle part respectively are connected with the sensing temperature meter of a detection reaction temperature in the kettle.The sensing temperature meter at three positions can be distinguished the temperature of detection reaction still top, middle part and bottom position, draws after the data each parameter on the conditioned reaction still correspondingly.The sensing temperature meter is located at the outer surface of reactor, is convenient to reading.
As preferably, be connected with agitator in the described reactor.The utility model also is applicable to the structure of belt stirrer in the reactor.
As preferably, described feed pipe and reactor upper end are tightly connected, and the feed pipe lower end is connected with distributor, and the reactor bottom is connected with circulating pump by pipeline, the circulating-pump outlet place is communicated with feed pipe, also is connected with material sucking port between reactor discharging opening and the circulating pump.When cancelling agitator in the reactor, feed pipe can pass through welded seal with the reactor top, circulating pump can be withdrawn into the material of reactor bottom the feed pipe place of reactor again, circulation repeatedly, promptly played the effect of agitator, keep the circulation and the mass transfer of material, thoroughly eliminate the existence in still inner transmission matter dead band.
As preferably, be connected with heat exchanger by pipeline between described circulating pump and the feed pipe.Material is circulation time outside, can carry out heat exchange in advance outside reactor, makes material enter reactor under suitable temperature, and reaction efficiency is higher.
As preferably, described inlet of circulating pump and exit all are connected with a ball valve, guarantee that material can only pass through in one direction.
Therefore, the utlity model has point for measuring temperature and increase to 3 points, increase kettle top gas phase and kettle middle part measuring control point by single-point, each position temperature conditions of accurate understanding system, and then accurately control other response parameter, improve product quality stability characteristics such as simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Parts, position and numbering among the figure: reactor 1, feed pipe 2, sensing temperature meter 3, distributor 4, circulating pump 5, material sucking port 6, heat exchanger 7, ball valve 8.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the spray polymerization reactor that has heat exchanger of this example, be used for polymerization EO/PO, as Fig. 1, a reactor 1 is arranged, but the top of reactor 1, middle part and bottom are connected with the sensing temperature meter 3 of a detection reaction temperature in the kettle.The reactor upper end is connected with feed pipe 2 by welded seal, and the feed pipe lower end feeds in the reactor and connects distributor 4.The upper end of feed pipe is connected with heat exchanger 7 by pipeline.Heat exchanger import department is connected with circulating pump 5 by pipeline, and pump inlet is connected the lower end of reactor 1 by pipeline.The import of circulating pump 5 and exit all are connected with a ball valve 8, and also are connected with material sucking port 6 between reactor 1 discharging opening and the circulating pump 5.
During use, raw material fed in the reactor 1 react, raw material is gone out from the reactor bottom under the effect of circulating pump 3, carry out heat exchange at heat exchanger 5 places then, reach suitable temperature, enter in the reactor secondary response again by feed pipe 2 again, so circulation is up to reacting completely.By temperature displayed on 3 sensing temperature meters 3, can accurately set the parameter on reactor, the heat exchanger, and then improve product quality stability.
