The utility model, can also be as the intensification thermostatic control of whole system by electric heater unit.
Accompanying drawing explanation
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, electric heater unit; 6, check valve; 7, circulating pump; 8, the second pipeline; 9, metal hose; 10, reactor; 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.
The specific embodiment
Below in conjunction with accompanying drawing, the specific 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 10, one end of reactor 10 is connected with input pipe 1 by the first pipeline 4, the other end of reactor 10 is connected with efferent duct 2 by the second pipeline 8, on the first pipeline 4, electric proportional-regulation valve 3 is installed, check valve 6 and circulating pump 7 have been installed in series between first pipeline 4 in electric proportional-regulation valve 3 exits and the second pipeline 8; On the first pipeline 4 and the second pipeline 8, be separately installed with metal hose 9, be positioned on the first pipeline on 4, between its electric proportional-regulation valve 3 and metal hose 9, electric heater unit 5 is also installed.
Between the electric heater unit 5 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 8 arranges the second measurement and control of temperature point B, in reactor 10, 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, for example, provide public 5 degree cooling water sources, need reactor reaction mass chilling temperature 15 degree controlled, after stoichiometric number hour, be warmed up to 60 degree thermostatic controls.Environment temperature 30 degree.
Reactor material is lowered the temperature from 30 degree, open electric proportional-regulation valve 3 and import 5 degree cooling water refrigerating mediums, reactor material starts cooling, when approaching 15, temperature constantly turns down the flow that flows into reactor refrigerating medium while spending, when approaching 15.5, close electric proportional-regulation valve 3 while spending, cut off refrigerating medium and flow into reactor 10, unlatching internal circulation pump 7 is that the refrigerating medium of chuck inside circulates, make reactor 10 temperature substantially maintain 15 degree ± 1 ℃, when the temperature sensor on the 3rd measurement and control of temperature point C is spent higher than 15.5, according to algorithm, control and enter reacting kettle jacketing refrigerating medium flow.Make the temperature-controlled precision of reactor material in whole process at ± 1 ℃.
Start to heat up and control, circulating pump 7 moves, cuts out electric proportional-regulation valve 3, opens electric heater unit 5.By accurate algorithm, make reactor material be warmed up to 60 and spend not overshoot.In this process, the heat-conducting medium of chuck may be warmed up to 95 degree (depending on heat transfer efficiency and stirring efficiency completely).
Electric heater unit 5 described in the utility model is used for playing the effect of intensification, constant temperature.
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 modification.
