Description
Technical field
The utility model relates to distillation process engineering device technique field more particularly to a kind of distillation process resin trap devices.
Background technique
Solvent in chemical production process has part material, impurity and its by-product and is dissolved in mother liquor, common
Solvent is to be recycled, and the subtractive process of mother liquor will have these and be dissolved in the precipitation process of the substance in mother liquor, these
Remnant is usually precipitated with resin-like, and the solvent gas phase that evaporator steams in distillation process enters after gas-liquid separator
The stripping section of destilling tower, the light component resin carried secretly in gas phase are separated, are being steamed together with the resin dissolved in solvent mother liquor
Aggregation in device is sent out, with the increase of distillation amount, resin is constantly precipitated, and the heat source of one side evaporator is not that steam is exactly thermally conductive
Oil, the variation for the tube wall temperature gradient that exchanges heat, the heavy constituent resin that part mobility can be made slow is attached on heating tube wall, with steaming
Send out the increase of resin concentration in device.Wall built-up phenomenon is increasingly severe, slowly will lead to resin fouling knot in evaporator heating pipe
Coke makes heat transfer deterioration；The entrainment of another aspect air foam can make resin enter destilling tower, and temperature is compared with temperature in evaporator in destilling tower
Low, some high boiling heavy constituents in entrainment can solidify and be attached to the surface of filler, reduce circulation area easily, make
Tower pressure drop increases, and heat and mass is impacted, and balance is destroyed.Therefore the present apparatus, by under certain temperature, the stream of resin are used
Dynamic property and gravity characteristic, into collecting tank in it is to be discharged, to ensure that the normal operation of distillation system.
Utility model content
In view of this, the utility model in view of the deficiencies of the prior art, develops a kind of situation operated normally in system
The fouling and coking of heat exchange tube wall and entrainment in evaporator can be overcome to cause high boiling heavy constituent mass sets down
The distillation process resin trap device for the shortcomings that being attached to the surface of filler, reducing circulation area.
The utility model solves above-mentioned technical problem by following technological means:
A kind of distillation process resin trap device, including resin trap tank, the lower end of the resin trap tank and blow-off valve
Connection, the blow-off valve are connected with drainage conduit；The upper end of the resin trap tank is connect with vomit pipe, and the vomit pipe upper end connects
Logical baiting valve, the other end of the baiting valve are connected to evaporator feeder pipe and gas-liquid separator feeder pipe respectively, the gas-liquid
Separator feeder pipe is connect with gas-liquid separator, and the gas-liquid separator is connected with the gas phase pipe for entering destilling tower；The evaporation
Device feeder pipe is connected with evaporator lower end, and the evaporator top is connected to evaporator gas phase pipe, the evaporator gas phase Guan Lian
It connects on gas-liquid separator.
The utility model has the beneficial effects that by opening dispensing valve, evaporator and pipe nipple under gas-liquid separator with put
Expect that valve is connected, the resin that Distallation systm generates will pass through dispensing valve and solvent enters collecting tank together, due to resin from
Body characteristic is fallen in collecting tank greatly by density, and with the increase of resin, solvent is replaced out, when resin canful, is closed
Dispensing valve is closed, discharge valve is opened and releases resin, do not affect the normal production, otherwise needs to stop distillation and releases resin, simultaneously
Part solvent is released together.So the resin that distillation process generates is by means of its mobility and gravity characteristic, it is rich in resin container
Collection, light component solvent and the layering of heavy constituent resin exist, and lead to heat source in resin container external jacket, and resin is in it due to temperature
The reason of still have certain mobility, resin is periodically discharged, to keep resin remaining quantity in evaporator few, evaporation process gas phase
Wash away and make the seldom wall built-up of a small amount of resin, to ensure that Distallation systm operates normally for a long time.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
In figure: 1- resin trap tank, 2- blow-off valve, 3- drainage conduit, 4- vomit pipe, 5- baiting valve, 6- evaporator feeder pipe,
7- evaporator, 8- evaporator gas phase pipe, 9- gas-liquid separator, 10- gas-liquid separator gas phase pipe, 11- gas-liquid separator feeder pipe.
Specific embodiment
The utility model is described in detail below with reference to attached drawing:
As shown in Figure 1:
A kind of distillation process resin trap device, it is characterised in that: including resin trap tank 1, the resin trap tank 1
Lower end is connect with blow-off valve 2, and the blow-off valve 2 is connected with drainage conduit 3；The upper end of the resin trap tank 1 and vomit pipe 4 connect
It connects, 4 upper end of vomit pipe is connected to baiting valve 5, and the other end of the baiting valve 5 divides with evaporator feeder pipe 6 and gas-liquid respectively
Be connected to from device feeder pipe 11, the gas-liquid separator feeder pipe 11 connect with gas-liquid separator 9, the gas-liquid separator 9 and into
The gas phase pipe 10 for entering destilling tower 12 is connected；The evaporator feeder pipe 6 is connected with 7 lower end of evaporator, 7 top of evaporator with
Evaporator gas phase pipe 8 is connected to, and the evaporator gas phase pipe 8 is connected on gas-liquid separator 9.
It is connected first by opening baiting valve 5, evaporator 7 and gas-liquid separator 9 and baiting valve 5, what Distallation systm generated
Resin will pass through baiting valve 5 and solvent and enter resin trap tank 1 together, due to the self-characteristic of resin, by the big sedimentation of density
In in resin trap tank, with the increase of resin, solvent is replaced out, when resin canful, closes baiting valve 5, the row of opening
Expect that valve 2 releases resin
The utility model has the beneficial effects that the resin that distillation process generates is being set by means of its mobility and gravity characteristic
Enrichment in rouge collecting tank, light component solvent and the layering of heavy constituent resin exist, and lead to heat source in resin container external jacket, and resin exists
Still there is certain mobility due to temperature in it, resin is periodically discharged, thus keep resin remaining quantity in evaporator few,
Washing away for evaporation process gas phase makes the seldom wall built-up of a small amount of resin, to ensure that Distallation systm operates normally for a long time.
Above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although referring to preferred embodiment pair
The utility model is described in detail, those skilled in the art should understand that, it can be to the technology of the utility model
Scheme is modified or replaced equivalently, and without departing from the objective and range of technical solutions of the utility model, should all be covered
