Description
Technical field
The utility model relates to synthesize solution polymerized rubber, belong to solution polymerized rubber stripping kettle top vapour phase purge column, it is especially a kind of
Solution polymerized rubber strips kettle top vapour phase purge column.
Background technique
Solution polymerized rubber refers to producing synthetic rubber by polymerisation in solution.Be by polymerized monomer under the action of catalyst, lead to
It crosses polymerisation in solution and prepares rubber.It polymerize in glue in addition to containing polymer rubber, the monomer also completed containing solvent and unreacted.
In order to separate solvent and unreacted monomer.Glue in solution polymerized rubber production generally uses elutriation method to complete solvent and rubber production
The separation of product.Glue i.e. containing solvent sprays into the stripping vessel with stirring, and same hot water, steam are mixed under the action of stirring
It closes, solvent, monomer flash of steam, is recycled into kettle top vapour phase is cooling, the rubber after removing solvent is suspended in as rubber grain
In hot water, postorder workshop section is sent to be further dried as finished product.
Rubber experienced several stages such as dispersion, heat absorption and vaporization in glue elutriation stripping process.Glue divides in the medium
It dissipates and forms the glue drop stage: due to the addition of water or vapor, being broken into the rubber of the equal very little of polarity and solvent in water
For glue drop one by one.
Solvent evaporation forms the oil-containing micelle stage: after glue is in addition to being dispersed into glue drop by the effect of water or vapor, from
Wherein absorb heat, make glue drip in solvent evaporation, into ambient liquid phase.It will form after solvent evaporation from inside micelle to surface
Numerous pores, form the loose spongiform oil-containing micelle that substantially reduces of solvent content；Into the solvent vapo(u)r of liquid phase main body
The material passed through in kettle together with vapor reaches kettle top vapor phase space.
Oil-containing micelle continues to remove the solvent naphtha stage: still containing about 5% solvent naphtha in preliminary molding solid-state micelle, also
Continue to recycle solvent therein, until solvent content drops to permissible value.The solvent inside oil-containing micelle was to surface before this
Molecule diffusion, enter micelle surface inside oil-containing micelle, then vaporization enters vapour phase.
By above-mentioned 3 stages, the task of recycling design and extraction rubber from glue is completed.It can be seen that elutriation
Stripping is the process of a large amount of steam stripping solvents.Water vapour passes through liquid phase with the solvent naphtha of vaporization together and flows out from stripping kettle top,
Inevitably it is entrained with solid rubber particle.These solid rubber particles can block postorder pipe-line equipment.
Strip blocking of the entrained solid particle to postorder pipe-line equipment in kettle top vapour phase in industrial production in order to prevent, one
As using filter remove solid rubber particle.The volume of filter is big, and cleaning is inconvenient.And the cycle of operation is short, and one week sometimes
Primary, large labor intensity will be cleared up, operating environment is severe.
Utility model content
The purpose of this utility model is to provide a kind of solution polymerized rubbers to strip kettle top vapour phase purge column, structurally reasonable, can
Effectively to extend filter runing time, postorder pipe-line equipment is avoided to block, realizes equipment long-term operation.
Purpose of the utility model is realized as follows: a kind of solution polymerized rubber strips kettle top vapour phase purge column, including contain intermingle with
The vapour phase purge column of rubber stripping vessel top exit connection, purge column is the tank body that sealing cap is respectively set in upper and lower ends, in upper envelope
Stripping kettle top vapor phase exit is set on cap, hot water outlet is set on lower sealing cap, in the stripping kettle top of tank body lower part setting
Vapour phase entrance is connected with stripping kettle top vapour phase delivery pipe, is arranged on the top of tank body and protrudes into the intracorporal hot-water line of tank, hot water
The spout of pipe downward, is from top to bottom successively uniformly staggered in the tank body below hot-water line spout and center dispersion is arranged
Disk and annular plate washer.
The utility model is used for the stripping process of solution polymerized rubber, and stripping kettle top vapour phase enters stripping kettle top vapour phase and rinses tower reactor
Lower inlet, top are hot water inlets, and inside is equipped with ring baffle, are rinsed with hot water to stripping kettle top vapour phase, except deentrainment
Rubber grain, stripping kettle top vapour phase enter stripping vessel from the outflow of purge column bottom from tower top outflow, hot water is rinsed, strip kettle top agent vapour
Mutually pass through hot water injection, remove entrained solids rubber grain, is 10 ~ 60 seconds rinsing dwell time in the tower, using ring baffle
The rubber grain carried secretly in stripping kettle top vapour phase is rinsed, hot water enters purge column on purge column top, strips kettle top vapour
Mutually enter purge column from purge column lower part.Ring baffle is installed inside purge column, every layer of ring dish baffle by center dispersion impeller,
It is mounted on the ring baffle composition of tower wall.The hot water that purge column entrance comes is introduced into center dispersion impeller, downward from dispersion plate edge
Flowing；It is ring baffle below the dispersion impeller of center, receives the hot water that center dispersion impeller comes, stripping kettle top vapour phase is dispersed by center
The gap of disk and ring baffle flows up, while hot water is rinsed stripping vessel vapour phase；Hot water on ring baffle continues
It flows downward, into lower layer's center dispersion impeller or enters purge column bottom, purge column uses 1 ~ 10 layer of ring dish baffle, the ring disk shape gear
The center dispersion impeller of plate and the spacing of ring baffle are 100-1000mm, and the purge column diameter is stripping kettle top vapour phase pipeline
3-10 times of caliber.
Hot water enters purge column on purge column top, strips kettle top vapour phase from purge column lower part and enters purge column.Purge column
The hot water that entrance comes is introduced into center dispersion impeller, flows downward from dispersion plate edge；It is ring baffle below the dispersion impeller of center, connects
The hot water that receipts center dispersion impeller comes, stripping kettle top vapour phase are flowed up by the gap of center dispersion impeller and ring baffle, simultaneously
Hot water is rinsed stripping vessel vapour phase, removes entrained solid rubber grain；Hot water on ring baffle continues to flow downward,
Into lower layer's center dispersion impeller or enter purge column bottom.By using purge column, entrained solid rubber grain can be effectively rinsed,
The stripping condenser front filter cycle of operation can accomplish two months or more.
The utility model is structurally reasonable, effectively extends filter runing time, avoids the blocking of postorder pipe-line equipment, real
Equipment long-term operation is showed.
