Shortcoming is: conduct heat inhomogeneous, Steam Heating easily causes DBP thermal decomposition.
Utility model content
Technical problem to be solved in the utility model is: a kind of homogeneous heating is provided, between heat-transfer effect is good, concentrate temperature is low, safe, contraposition mixes two-(tert-butyl hydroperoxide isopropyl) benzene concentration unit.
For technical solution problem, the utility model adopts following technical proposals: a kind of, contraposition mix the concentration unit of two-(tert-butyl hydroperoxide isopropyl) benzene, comprise concentrate device and condenser, wherein,
Described condenser is cooling water condensation device and chilled water condenser, and described cooling water condensation device is connected with chilled water condenser, and chilled water condenser is connected with vavuum pump;
Described concentrate device comprises kettle, has charge pipe above kettle, and there is discharging opening below, and heating tubulation is set in kettle, and this heating tubulation is connected with hot-water line, and described cooling water condensation device is connected with described concentrate device.Because using inner heating tubulation to conduct heat, heat-transfer effect is good, and can make material fully roll; Adopt in addition hot water heating, can effectively prevent DBP thermal decomposition, improve production security.
On such scheme basis, described heating tubulation is located at the bottom in concentrate device, is connected 50～80 ℃ of hot water temperatures with independent hot water heating pipe.
Method of work of the present utility model is: in concentrate process, divide and add running water 3 times, the addition of the whole process running water of single still concentrate is not more than 10% of concentration liquid total amount, and controlled pressure is normal pressure～-0.095MPa.
On such scheme basis, described cooling water condensation device is independent refrigerant, and this coolant media is water.
On such scheme basis, described chilled water condenser is independent refrigerant, and coolant media is the ethylene glycol solution of-5～3 ℃.
The beneficial effects of the utility model are: adopt hot water as heat medium, make concentrate temperature lower, overcome the shortcoming of tradition with low-pressure steam heating, can not cause DBP to decompose, homogeneous heating, heat-transfer effect are good, and the inner heating of concentrate device tubulation can make material fully roll; Can effectively prevent DBP thermal decomposition, blast, improve production security.
