The automatic deodorizing device comprises a deodorizing reaction kettle (1), a condenser (2), a vacuum pump (3) and a condensate recycling tank (4), and is characterized in that a steam inlet is formed in the bottom of the deodorizing reaction kettle (1) and is connected with a steam delivery pipeline (5); the steam delivery pipeline (5) is provided with an electromagnetic valve (6); the deodorizing reaction kettle (1) is provided with a detector (7); and a control system is arranged for controlling connection between the electromagnetic valve (6) and the detector (7). The detector is used for detecting the content or the concentration of styrene in the deodorizing reaction kettle, then the control system controls opening of the electromagnetic valve arranged on the steam delivery pipeline, and a deodorizing process is controlled; and the automatic deodorizing device is simple in control, convenient to use, high in automation degree and high in efficiency.
Description
Technical field
The utility model relates to a kind of chemical reaction still, particularly the automatic deodorization device of a kind of polymer polyatomic alcohol production process.
Background technology
Polymer polyatomic alcohol is being commonly called as of the poly-enzyme polyalcohol of polymer graft, is take general poly-enzyme polyalcohol as the basis, adds that propylene is cured, styrene and initator azodiisobutyronitrile, carries out free yl graft polymerization and form under nitrogen protection.
After polymerisation finishes, residual in the reaction system have monomers such as unreacted styrene, not only make product that very large peculiar smell is arranged, and harmful, thereby need deodorization (removing wherein unreacted styrene monomer and other micromolecular compound), alleviate the smell of polymer polyatomic alcohol product.
The conventional method of deodorization is to add water in reaction system in the polymer polyatomic alcohol production process, makes reaction system heat up, vacuumize deodorization through Steam Heating again, length consuming time, and deodorization efficiency is lower, and the waste steam heat.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of automatic control, the automatic deodorization device of polymer polyatomic alcohol production process that deodorization efficiency is high.
The technical scheme that its technical problem that solves the utility model adopts is: the automatic deodorization device of a kind of polymer polyatomic alcohol production process, comprise deodorization reactor, condenser, vavuum pump and lime set recycling can, it is characterized in that: described deodorization reactor bottom is provided with a steam inlet, the steam inlet connects steam pipeline, steam pipeline arranges magnetic valve, the deodorization reactor arranges detector, and magnetic valve and detector arrange connection control system.
Detector is for detection of cinnamic content or concentration in the deodorization reactor, and the magnetic valve that then is arranged on the steam pipeline by control system control is opened.Steam from public work directly enters into the deodorization reactor by deodorization reactor steam inlet from the bottom, after mixing of materials wherein, vacuumize through vavuum pump, remove the little molecule such as unreacted styrene monomer and water in the polymeric reaction product, styrene monomer and water etc. enter described condenser, after the condensation condensate liquid at Action of Gravity Field downstream to the lime set recycling can.
Wherein preferred version is:
Described condenser condenses liquid outlet connects the lime set recycling can, and the lime set recycling can is positioned at the below of condenser, and condenser is coiled.Absorption heat-exchange is effective, improves condensation efficiency.
The beneficial effect that the automatic deodorization device of the utility model polymer polyatomic alcohol production process has is: by being provided with a steam inlet in deodorization reactor bottom, the steam inlet connects steam pipeline, steam pipeline arranges magnetic valve, the deodorization reactor arranges detector, magnetic valve and detector arrange connection control system, detector is for detection of cinnamic content or concentration in the deodorization reactor, then the magnetic valve that is arranged on the steam pipeline by control system control is opened, the control deodorising process, control is simple, easy to use, automaticity is high, and efficient is high.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1, deodorization reactor 2, condenser 3, vavuum pump 4, lime set recycling can 5, steam pipeline 6, magnetic valve 7, detector.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1: deodorization reactor 1 connects vavuum pump 3 by condenser 2.Deodorization reactor 1 bottom is provided with a steam inlet, and the steam inlet connects steam pipeline 5, and steam pipeline 5 arranges magnetic valve 6, and deodorization reactor 1 arranges detector 7, and magnetic valve 6 and detector 7 arrange connection control system.
Operation principle and use procedure:
Detector is for detection of cinnamic content or concentration in the deodorization reactor, and the magnetic valve that then is arranged on the steam pipeline by control system control is opened.Steam from public work directly enters into the deodorization reactor by deodorization reactor steam inlet from the bottom, after mixing of materials wherein, vacuumize through vavuum pump, remove the little molecule such as unreacted styrene monomer and water in the polymeric reaction product, styrene monomer and water etc. enter described condenser, after the condensation condensate liquid at Action of Gravity Field downstream to the lime set recycling can.
