Through the above technical solutions, the utility model is attainable to have the beneficial effect that the design of the utility model structure is simple
Rationally, easily operated, in addition to other than reaction kettle sandwich establishment carry out it is cooling outer, it is cold also by the coil pipe being arranged in reaction kettle
But liquid directly cools down the material in reaction kettle, and spiral helicine coil pipe film-cooled heat increases, and can be quickly cooled down material；Together
When the external coolant circulation system of coil pipe, improve production efficiency, ensure that product quality.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Specific embodiment
As shown in Fig. 1, cooling device in one kind 2,5- dimethoxy-tetrahydrofuran hydrolysis reaction, including reaction kettle
1, interlayer 2 is equipped with outside reaction kettle 1,2 top of interlayer is equipped with cooling liquid inlet, and lower part is equipped with cooling liquid outlet, leads in interlayer cold
But liquid carries out cooling down to reaction kettle 1.1 top of reaction kettle is equipped with kettle cover, and kettle cover is equipped with feed inlet 3, will lead from feed inlet 3
Reaction mass 2 is wanted, 5- dimethoxy-tetrahydrofuran is passed through in kettle, and 1 lower part of reaction kettle is equipped with discharge port 4, in the reaction kettle 1
Portion is equipped with agitating shaft 5, guarantees that reaction mass is sufficiently mixed；2,5- dimethoxy-tetrahydrofuran hydrolysis are exothermic reaction, single
Temperature environment needed for not being able to satisfy reaction system is cooled down by interlayer 2, therefore coil pipe 6, coil pipe are set inside the reaction kettle 1
6 in the shape of a spiral, and helical form can effectively increase and reaction solution contact area.The cooling liquid inlet 61 of coil pipe 6 is located at 1 top of reaction kettle
Outside, cooling liquid outlet 62 are located at 1 lower outside of reaction kettle；Cooling liquid inlet 61 is connect by pipeline with fluid reservoir 7, on pipeline
Equipped with pump 8；Cooling liquid outlet 62 is connect by pipeline with cooler 9, and coolant liquid takes away the heat of reaction solution in kettle by coil pipe 6
Amount, the temperature of coolant liquid can increase, need to be cooled down the coolant liquid flowed out from coil outlets 62 with cooler 9, cold
But device 9 is connect by pipeline with fluid reservoir 7, coolant liquid after cooling will be delivered in fluid reservoir 7 again, by pumping 8 for liquid storage
Coolant liquid in tank 7 is pumped to 6 import of coil pipe；Cooling liquid inlet 61 and pump 8 between be equipped with the first valve 10, cooling liquid outlet 62 with
The second valve 11 is equipped between cooler 9, valve can control the size of coolant liquid burst size according to real reaction situation.
In order to avoid in cooling procedure, coil pipe 6 shakes, bottom is equipped with fixed frame 12 in reaction kettle, and coil pipe 6 is fixed
On fixed frame, coil pipe 6 is supported.
Kettle cover is equipped with temperature sensor 13, convenient for being measured in real time to temperature in the kettle, to control the disengaging of coolant liquid
The size of amount.
