The device improves the efficiency for separating the ECH and reduces the using quantity of steam.
Description
Technical field
The utility model relates to the device of a kind of separation ECH (epoxy chloropropane), comprises main reactor, condenser, phase-splitting bucket, ECH groove and tank.
Background technology
Resins, epoxy (Epoxy) is called Albertol, artificial resin, Resin adhesive etc. again.Be the important thermosetting resin of a class, be widely used in tamanori, purposes such as coating.Resins, epoxy (Epoxy resins/Epoxy/Polyepoxide) is thermoset epoxy thing polymkeric substance.Most of Resins, epoxy by epoxy chloropropane (ECH) (epichlorohydrin) (C3H5ClO) and dihydroxyphenyl propane (phenol methane) (bisphenol-A) (C15H16O2) produce chemical reaction and form.Epoxy chloropropane (ECH) is the important raw and processed materials of producing Resins, epoxy, and epoxy chloropropane is to prepare by the two-step reaction to the raw material chlorallylene, at first is and hypochlorous acid generation hydrochlorination to obtain two blended alcohol:
CH2＝CHCH2Cl+HOCl→HOCH2CHClCH2Cl/ClCH2CH(OH)CH2Cl
In second step, alcohol mixture and alkali reaction are generated epoxide:
HOCH2CHClCH2Cl/ClCH2CH(OH)CH2Cl+NaOH→CH2CHOCH2Cl+NaCl+H2O
Therefore, we will obtain ECH, just must dewater to mixture, the separation ECH apparatus structure that we adopted at present as shown in Figure 1, comprise: reactive tank, condenser, pipeline, two phase-splitting buckets, and tank and ECH groove, main reactor links to each other with the import of condenser by pipeline, and the outlet of condenser links to each other with the import and the ECH groove of phase-splitting bucket respectively by pipeline, pipeline between condenser and ECH groove and condenser and the phase-splitting bucket all is provided with valve, and the outlet of phase-splitting bucket links to each other by the pipeline main reactor.We heat main reactor, here our heating means of employing are to send steam in main reactor, mixture in the main reactor will become steam, and mixture steam enters condenser by pipeline, because the condensation point of ECH and water is different, through behind the condenser, ECH is separated earlier, flow into the ECH groove, and water can flow into the phase-splitting bucket, this process, we are called dehydration.Water in the phase-splitting bucket, also can contain part ECH, can be divided into two-layerly in the phase-splitting bucket through after a while because density is different, ECH is because density is big, below sinking to, in this time, we can discharge the water in the phase-splitting bucket, and remaining mixture is delivered to main reactor again, this process, be called and take off ECH, use two phase-splitting buckets here, carry out taking off ECH twice.
The problem that present stage exists is, the ECH that volatilizes in reaction process is back to main reactor again after the phase-splitting again through condensation, and then multiple carries out above operation, causes the time of whole process longer, influences production capacity, but also consumed steam more.
The utility model content
The utility model provides a kind of can the raising to separate ECH efficient, reduces the ECH tripping device of steam consumption.
In order to solve above technical problem, we are provided with valve A by the pipeline between phase-splitting bucket and main reactor, and the pipeline of band valve B is arranged between this valve and the phase-splitting bucket, and this pipeline links to each other with the ECH groove.
Main reactor is heated, mixture in the main reactor will become steam, and mixture steam enters condenser by pipeline, because the condensation point of ECH and water is different, through behind the condenser, part ECH is separated earlier, and the mixture of remaining ECH and water enters the phase-splitting bucket, takes off ECH in the phase-splitting bucket, after the phase-splitting bucket is finished this step, valve-off A opens valve B, allows the ECH in the phase-splitting bucket flow in the ECH groove.After finishing this step, valve-off B opens valve A, allows mixture flow go into main reactor.Like this, the ECH that the main reaction section is evaporated directly is back to the ECH groove, thereby makes the ECH of this part to be back in the main reactor again, has reduced the time of separating ECH, has saved the consumption of steam.
Respectively getting ten grooves before and after improving analyzes steam total amount, dewatering time, one section and takes off ECH time, two sections and take off ECH
Respectively get ten grooves before and after improving and analyze steam total amount, dewatering time, one section and take off ECH time, two sections and take off the ECH time, specifically improve effect and see the following form:
Conclusion: can be got by statistics, every groove can be saved steam 1935kg, can save time 13 minutes.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is separation epoxy chloropropane (ECH) schematic representation of apparatus of prior art;
Fig. 2 is separation epoxy chloropropane of the present utility model (ECH) schematic representation of apparatus.
Embodiment
Shown in Figure 2, main reactor links to each other with the import of condenser, the outlet of condenser links to each other with the import and the ECH groove of phase-splitting bucket respectively, through behind the condenser, part ECH is separated and delivers to the ECH groove, also have the mixture of part ECH and water to be sent to the phase-splitting bucket, be provided with valve between the outlet of phase-splitting bucket and the main reactor, the outlet of phase-splitting bucket also is connected with the ECH groove with tank, and the centre is provided with valve, when finish two sections take off ECH after, close the valve between phase-splitting bucket and the main reactor, open the valve between phase-splitting bucket and the ECH groove, because ECH density is big, ECH can be in lower floor, water is on the upper strata, at this time open valve, the ECH of lower floor can flow in the ECH groove, after this step is finished, close the valve between phase-splitting bucket and the ECH groove, open the valve between phase-splitting bucket and the main reactor, allow the mixture flow of ECH and water in main reactor, proceed reaction.
