Background technology
Reactor is one of a kind of equipment very common in chemical enterprise.In reactor, main generation is chemical reaction, and therefore, the temperature of reactor degree is controlled has very high requirement.
At present, in each Chemical Manufacture enterprise, all exist reactor to need the problem that constantly heats up and lower the temperature, especially, to the reactor of some pilot scales, as need heat up, only need heat and get final product the reactor outside, lowering the temperature be an insoluble problem.Many enterprises adopt the cooling method of nature to be lowered the temperature to reactor, but reaction temperature and reaction time in reactor are all that strict standard is arranged; Also have minority enterprise to adopt the cooling or external heat exchangers system of coil pipe to be lowered the temperature to reactor, but its complex structure, clean difficulty, input cost is high and heat energy is cooled, and water is taken away and can't be reclaimed.Therefore, how give the reactor rapid temperature rise and drop and reclaim as far as possible heat energy and become one of difficult problem that present urgent need will solve.
The utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, but and provides a kind of also reactor of fast cooling that is rapidly heated.
In order to achieve the above object, but the reactor of the designed a kind of accurate temperature controlling of the utility model comprises reactor, tank for coolant and heating fluid case, is provided with paddle in reactor, and the paddle top is provided with motor; Described reactor outside is coated with shell, between shell and reactor, forms interlayer; Described shell is provided with liquid inlet and liquid outlet, and described liquid inlet is arranged on the bottom of shell, and the liquid inlet place is provided with pump, and described liquid outlet is arranged on the top of shell; Described tank for coolant is connected by pipeline with liquid inlet and the liquid outlet of shell respectively, and junction is equipped with valve; Described heating fluid case is connected by pipeline with liquid inlet and the liquid outlet of shell respectively, and junction is equipped with valve.
As preferably, described tank for coolant and heating fluid case are by pipeline communication, and pipeline is provided with valve.
As preferably, described tank for coolant is identical with the liquid in the heating fluid case, and boiling point is higher than 100 ℃.
As preferably, described heating fluid box top is provided with exhaust outlet, and prevention pressure in the heating fluid case in the process of heating is excessive, and the heating fluid case is caused to damage; Described heating fluid case can adopt electric heater unit to heat it.
But the reactor of the resulting accurate temperature controlling of the utility model, while needing to heat in reactor, after opening electric heater unit in the heating fluid case liquid in it being heated, open the valve at heating fluid case and shell liquid inlet place, under the effect of pump, make heating fluid enter in the interlayer of reactor and shell, it is heated reactor, then get back in the heating fluid case by liquid outlet; While needing to lower the temperature in reactor, open the valve at tank for coolant and shell liquid inlet place, under the effect of pump, cooling fluid enters in the interlayer of reactor and shell, reactor is carried out cooling, then gets back in tank for coolant by liquid outlet; Can open the valve on the pipeline be communicated with between them when liquid volume is uneven in tank for coolant and heating fluid case, thereby make its internal volume consistent.This reasonable in design, effectively utilize being communicated with of interlayer and tank for coolant and heating fluid case, effectively heat up and lower the temperature in inside to reactor, the heating fluid of reactor and cooling fluid storage tank are separated fully, do not use the complex appts such as heat exchanger and coil pipe, the accurate control of the intensification of realization response still and cooling at low cost, thus input cost reduced.
As an optional scheme, in tank for coolant and heating fluid case, liquid also can carry out pre-cold-peace preheating before normal operation, so greatly in the use procedure of accelerated reaction still, heated up and cooling rate.
