Utility model content
The applicant is for the shortcoming in above-mentioned existing production technology, a kind of reactor rational in infrastructure refrigerating medium assignment control is provided, thereby can realize Automatic Control and enter the flow of reactor refrigerating medium, accurately control the temperature of reactor reaction mass, improve temperature-controlled precision, improved the stability of product.
The technical scheme that the utility model adopts is as follows:
A kind of reactor refrigerating medium assignment control, comprise reactor, one end of described reactor is connected with input pipe by the first pipeline, the other end of described reactor is connected with efferent duct by the second pipeline, on described the first pipeline, electric proportional-regulation valve is installed, retaining valve and ebullator have been installed in series between first pipeline in electric proportional-regulation valve exit and the second pipeline; On described the first pipeline and the second pipeline, be separately installed with metal hose.
Further improvement as technique scheme:
Between the electric proportional-regulation valve of the first pipeline and metal hose, be provided with the first measurement and control of temperature point, the one end that is positioned at the metal hose of the second pipeline arranges the second measurement and control of temperature point, in described reactor, be provided with the 3rd measurement and control of temperature point, on described the first measurement and control of temperature point, the second measurement and control of temperature point and the 3rd measurement and control of temperature point, be separately installed with temperature sensor.
The beneficial effects of the utility model are as follows:
The utility model compact conformation, reasonable, easy to use and reliable, can control by the utility model the flow that enters reactor refrigerating medium easily, accurately controls the temperature of reactor reaction mass.The utility model is widely used in the temperature regulating device of reactor, enters the flow of the refrigerating medium of reactor by adjusting, controls the temperature of reactor.Each reactor is other places a refrigerating medium assignment control, and one group of unified low-temperature receiver or thermal source are by refrigerating medium assignment control and can realize the accurate control of each reactor temperature of charge, have greatly improved the stability of product.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1, input pipe; 2, efferent duct; 3, electric proportional-regulation valve; 4, the first pipeline; 5, retaining valve; 6, ebullator; 7, the second pipeline; 8, reactor; 9, metal hose; A, the first measurement and control of temperature point; B, the second measurement and control of temperature point; C, the 3rd measurement and control of temperature point.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, the reactor of the present embodiment refrigerating medium assignment control, comprise reactor 8, one end of reactor 8 is connected with input pipe 1 by the first pipeline 4, the other end of reactor 8 is connected with efferent duct 2 by the second pipeline 7, on the first pipeline 4, electric proportional-regulation valve 3 is installed, retaining valve 5 and ebullator 6 have been installed in series between first pipeline 4 in electric proportional-regulation valve 3 exits and the second pipeline 7; On the first pipeline 4 and the second pipeline 7, be separately installed with metal hose 9.
Between the electric proportional-regulation valve 3 of the first pipeline 4 and metal hose 9, be provided with the first measurement and control of temperature point A, the one end that is positioned at the metal hose 9 of the second pipeline 7 arranges the second measurement and control of temperature point B, in reactor 8, be provided with the 3rd measurement and control of temperature point C, on the first measurement and control of temperature point A, the second measurement and control of temperature point B and the 3rd measurement and control of temperature point C, be separately installed with temperature sensor.
In actual use procedure, for example, provide public 5 degree cooling water sources, need the reactor 8 reaction mass chilling temperatures 15 of controlling to spend.Environment temperature 30 is spent.
The interior material of reactor 8 is lowered the temperature from 30 degree, open electric proportional-regulation valve 3 and import 5 degree chilled water refrigerating mediums, the interior material of reactor 8 starts cooling, when approaching 15, temperature constantly turns down the flow that flows into reactor 8 refrigerating mediums while spending, close electric proportional-regulation valve 3 while spending when approaching 15.5, cut off refrigerating medium and flow into reactor 8, unlatching internal circulation pump 6 is that the refrigerating medium of chuck inside circulates, make reactor 8 temperature substantially maintain 15 degree ± 1 DEG C, in the time that the temperature sensor on the 3rd measurement and control of temperature point C is spent higher than 15.5, according to algorithm, control enters reacting kettle jacketing refrigerating medium flow.Make the temperature-controlled precision of reactor 8 materials in whole process at ± 1 DEG C.
The design of the utility model ebullator 6, has formed the inner loop loop of refrigerating medium assignment control, detected temperatures easily, and the temperature symmetry of 2 of the first measurement and control of temperature point A and the second measurement and control of temperature point B.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of amendment.
