In one embodiment, on the axial side wall of collection surface, also be furnished with cohesion water and overflow pipeline, its residing position is lower than the height of residing position of wet solvent recovery channel and said filter screen.In a preferred embodiment, overflow the liquid level control tube that is furnished with a form of tubes on the pipeline, the level control valve door that is used to regulate the liquid level in the said collection surface is housed on the liquid level control tube at cohesion water.
The cohesion water of this design overflows pipeline to make when the cohesion water excess in the collection surface, can in time adjust liquid level, rather than lets alone to discharge, thereby reduces the loss of polymers soln.Be that cohesion water overflows the quantity of pipeline and the quantity of liquid level control tube can be decided according to practical situation with being appreciated that.
In one embodiment, the water vapour pipeline drenches pipeline and is connected with the bottom of said collection surface through Common Ducts with leading, and the sieve aperture in the bottom surface portions of said Common Ducts and said filter screen aligns.In a preferred embodiment, with leading to drench on the pipeline valve is installed all at the water vapour pipeline.
Compared with prior art, the beneficial effect of the utility model is: in collection surface, arranged filter screen, thereby reduced even avoided the adhesion of wet micelle on the collection surface inwall fully.Arranged also that on cohesion equipment the cohesion water that comprises the liquid level control tube overflows pipeline, and on the liquid level control tube, be furnished with valve.Can directly control the amount of cohesion water through the valve on the liquid level control tube, avoid condensing the water overfill and overflow and lose product.Through leading the pouring pipeline, can be easily to cohesion after heat water sampling, and realize control process parameters thus; And after agglomeration process finishes, can directly from lead the pouring pipe, will condense water and emit, need not to topple over whole collection surface, greatly reduce manual operation labour intensity and risk.During the steam stripping coacervation that the collection surface of the utility model also can be widely used in polymkeric substance that solution polymerization process obtains and solvent separates.
Description of drawings
To come the utility model is described in more detail based on various embodiment and with reference to accompanying drawing hereinafter.Wherein:
Fig. 1 is the structural representation according to the cohesion equipment of the utility model;
Fig. 2 is the plat according to the bottom surface portions of the filter screen of the utility model.
Embodiment
To combine accompanying drawing that the cohesion equipment of the utility model is further specified below.
Fig. 1 has shown the cohesion equipment 20 according to the utility model, and it comprises the loam cake 4 in collection surface 1 and the open top that covers collection surface 1.Collection surface 1 for example is constructed with the barrel-like structure of sidewall and bottom, and loam cake 4 for example can link to each other with collection surface 1 through hinge.The circumferential side wall of collection surface 1 be provided with wet solvent recovery channel 3 than the upper part, and be provided with water vapour pipeline 8 in the bottom of collection surface 1 and drench pipeline 9 with leading.
In the inside of collection surface 1 filter screen 2 is installed.The shape of filter screen 2 is configured to roughly be complementary with the inner wall shape of collection surface 1, and preferably in assembling, becomes the spaced apart certain distance of inwall with collection surface 1.In the embodiment shown in fig. 1, this filter screen 2 comprises sidewall sections and bottom surface portions.In a preferred embodiment, the height of filter screen 2 is lower than the height of collection surface 1, and is not higher than wet solvent recovery channel 3 positions.
According to the utility model, filter screen 2 only includes sieve aperture in its bottom surface portions, and at the sidewall sections non-mesh.Sieve aperture is preferably circle, but also can be any other suitable shape.In an example, the diameter of sieve aperture is 2-50mm, is preferably 5-20mm.As shown in Figure 2, sieve aperture is arranged to the regular hexagon of rule on the whole on bottom surface portions.
On collection surface 1, also be provided with cohesion water and overflow pipeline 6, it is provided for discharging unnecessary cohesion water, and its quantity can be selected as the case may be, and its present position is lower than the height of filter screen 2.In the embodiment shown in fig. 1, cohesion water overflows the liquid level control tube 5 that pipeline 6 also comprises a form of tubes, on this liquid level control tube 5, level control valve door 7 is housed also.Liquid level control tube 5 can be used for regulating the cohesion water liquid level in the collection surface 1 with level control valve door 7.The amount of the polymers soln of handling when needs hour can be opened level control valve door 7, reduces water level in the collection surface, reduces water vapour consumption, to reach the energy-saving and emission-reduction purpose.
Water vapour pipeline 8 drenches pipeline 9 and can communicate with collection surface 1 through pipeline separately with leading.In the embodiment shown in fig. 1, water vapour pipeline 8 drenches pipeline 9 and communicates with collection surface 1 through a common pipeline 13 with leading.In a preferred embodiment, the sieve aperture on the bottom surface portions of pipeline 13 and filter screen 2 aligns.With leading to drench on the pipeline 9 valve is installed all at water vapour pipeline 8, wherein valve 11 can be led the valve 12 that drenches on the pipeline 9 and then be used as showering guilding valve in the control steam flow on the water vapour pipeline 8.
In the actual process process, at first filter screen 2 is installed in the collection surface 1, add appropriate amount of deionized water then, close loam cake 4.Valve-off 12 is opened and by-pass valve control 11, guarantees to the water vapour that feeds certain flow in the filter screen 2 (shown in left arrow under among Fig. 1).After the boiling of the deionized water in the filter sieve net 2, open loam cake 4, add polymers soln rapidly and build loam cake 4.As separate medium, make thorough mixing and intensification in polymers soln and the superheated water filter screen 2 in collection surface 1 with superheated water.In the process of heating, most solvents are flashed vaporization, make wet solvent through recovery channel 3 recoverys that be condensed, and unnecessary cohesion water are discharged through cohesion water spillway 6, the agglomeration process of completion polymers soln.
After agglomeration process finishes, close water vapour valve 11, filter screen 2 is taken out from collection surface 1.Because the existence of filter screen 2, the micelle that therefore can when leaching cohesion water, will wet intactly is retained in the filter screen 2, only has a small amount of wet micelle to stick on the inwall of collection surface 1, and can easily clean out.
Last shut-off valve 11 is opened showering guilding valve 12 and will be condensed water from all emitting (shown in following right arrow among Fig. 1) leading the pouring pipe.For specific glue kind, also can directly access part cohesion water, to be used to analyze pH value or chloride ion content etc. through opening showering guilding valve 12.For the situation that need not to change cohesion water, can prepare at least two filter screens and supply to use in turn, so not only practice thrift pool time, and reduced labor intensity of operating personnel and work risk.
When the treatment capacity of polymers soln hour, can open level control valve door 7, reduce cohesion inner bucket water position, reduce water vapour consumption, reach the energy-saving and emission-reduction purpose.
Though the utility model is described, under the situation of the scope that does not break away from the utility model, can carries out various improvement and can replace parts wherein to it with equivalent with reference to preferred embodiment.The utility model is not limited to disclosed specific embodiment in the literary composition, but comprises all technical schemes in the scope that falls into claim.
