Preferred embodiment below with reference to drawings attached is done further explanation to the present invention, and those skilled in the art can therefrom recognize other many purposes and advantages potential in the invention.
Description of drawings
Fig. 1 for by the capturing device schematic diagram of preferred embodiment of the present invention and
Fig. 2 is along the generalized section of B-B in Fig. 1 capturing device.
The specific embodiment
Describe by the synthetic a kind of capturing device that is suitable for of producing of resin of the present invention in more detailed mode now.
Schematically expressed the capturing device by preferred embodiment of the present invention among Fig. 1.It is suitable for, and resin is synthetic to be produced.
Be positioned at the middle part of this body 10, settled a thermoregulating system 20.
Be to advance only control system by the medium that valve and pipeline constitute on the top of body 10, the housing.Medium only advances, and control system has comprised the flushing valve 40 that medium advances to end control valve 51 and join with the waste water pipeline.
Medium advances upper left quarter that control valve 51 only is positioned at Fig. 1, is air inlet upstream side direction, is arranged on the reactor (not shown) to join on the pipeline.
40 of flushing valves and medium advance to end control valve 51 and adjoin, also in air inlet upstream side direction; Be in the left side top by a central partition plate 12 that is fixed in shell 10 tops and extends downwards.Flushing valve 40 will from the input of air inlet upstream side, be pooled to the bottom of trap subsequently via the waste water of a minute slide tower, cooling tower under reactiveness.
This capturing device makes capturing device function in an acting capacity of the waste water storage effect by the intelligent change management of pipeline approach; Meanwhile also play the flushing action to passage, thereby saved the occupation of land space of equipment, improved efficient greatly and reduced production cost.The flushing valve facility also is set on the body right side also is feasible certainly in order to enlarge its flushing action.
Two parts about central partition plate 12 is separated into the inside of body 10 because 12 on dividing plate extends to an intrinsic suitable height and position, so make trap constituted one from top to bottom, turn back after from bottom to top a passage.As shown in Figure 1, successively be furnished with on this passage respectively and tilt downwards from central partition plate 12 and outer cover body 11, play a series of wing-shaped plate 13 of barrier effect.Such layout be intended in the limited space to prolong institute by the path of medium in trap, it is had manyly contact and the chance that acts on and time with thermoregulating system 20 (hereinafter more detailed description will be arranged) efficient of medium temperature being controlled with raising.
Be positioned at Fig. 1 upper right quarter, be the downstream direction of air flue, also be the end of trap reentrant pathway, be provided with a pressure regulating system and one and put the control system that medium is only gone to the vent gas treatment part.
Pressure regulating system includes to be supplied with a by-pass valve control 321 that joins on the negative pressure line with Vacuum Pumps Station (not shown) and is arranged on a control valve 52 on the emptying pipeline.
That adjoins with it is one and puts the control system that medium is only gone to vent gas treatment part (not shown).It has comprised a drain valve 311, and drain valve 311 is provided in a side of on the pipeline that is connected with an exhaust gas processing device of downstream direction; And corresponding pipe-line system (not shown).Select as another kind, control valve 52 also can merge with drain valve 311.
As previously mentioned, body 10 also includes a central partition plate 12 that is fixed in cover top portion and extends downwards; Be fixed in a series of wing-shaped plate 13 that this outer casing inner wall and central partition plate, its free end stretch to oblique below.And the waste water quantity that a collection of synthetic operation cycle that feeds intake generates will be considered in dividing plate 12 downward position in body, need make in the body bottom and leave enough volumes.
Wing-shaped plate 13 can have influence on MEDIA FLOW the short long of path of flowing through in the corner dimension of horizontal direction in body 10 in crossing the center line longitudinal cross-section, in other words, angle is more little just may to make the path lengthening at the more wing-shaped plate 13 of layout on the effective vertical extension; But angle is more little, is unfavorable for that more the wing-shaped plate retentate flows to down the concentrated of body bottom by deadweight.General this angle is limited in 10 degree to 70 degree, and is more preferably 30 degree to about 45 degree.
As mentioned above, a closing pipe line system that run through a series of pipes 26 (seeing Fig. 2 for details) of this series wing-shaped plate 13, constitutes with the connecting pipe of upper lower burrs row (adopting schematically showing of simplifying among Fig. 1).It passes this body up and down again respectively.The valve matched with this pipeline includes two groups of valves 201,202; 203,204.They are by being connected the conversion that realizes controllable way with external cooling water with steam station feed system (not shown).Such conversion makes that the applicability of trap is expanded.
For example in the synthetic production process of resin, from the medium that reactor is discharged, can be entrained with the materials such as acids that do not reach reaction, the MEDIA FLOW of flowing through behind the fractionation cooler can be at trap along forming crystallization in the passage of warp, and it is not smooth that discharge medium is flowed, and causes production procedure to continue.This just need be by changing environment in the trap temperature regime so that crystals melt is pooled to the trap bottom further processes.
Capturing device has just comprised a bottom thermosistor 21 and a product tapping equipment 60.Can make the thing that compiles of bottom do property processing respectively.
What below list is each main valve event state list when being in reaction, finding time and clearing up three kinds of states about capturing device in the synthetic production process of vinyl unsaturated-resin, for your guidance.
In this example, each valve event of capturing device is by intelligent control system (not shown) follow procedure control hormany operating, and according to the production technology regulation realize this trap in reaction, find time and clear up to change between three kinds of states.The setting of this multi-functional state conversion can make to the greatest extent in the mounting medium of reaction the useful component enrichment so that its recycling.
Above content has shown and has described preferred embodiment of the present invention.The embodiment that this just shows by example, purpose is explanation, rather than will limit the invention.Self-evident, to one skilled in the art, under the situation that does not break away from aim of the present invention, can carry out numerous variations, variation and replacement to it.Content of the present invention is to be limited by the essence of additional claim and scope.
