Abstract
The utility model discloses a kind of stripper and add defoamer device, including stripper, and it is communicated to slurry feeding line and the defoamer charge line of stripper, described slurry feeding line is communicated to eight layers of tower tray of stripper, and described defoamer charge line is communicated to eight layers of tower tray top of stripper.The use of this device avoids eight layers of tower tray buildup of stripper and affects steam stripped stable operation, effectively avoids stripper putty, decreases the frequency cleaning stripper simultaneously, improve the stable operation index of stripper in PVC Production Process；Also can guarantee that stripper effectively removes the vinyl chloride in polyvinyl chloride pulp, it is ensured that in sold resin, content of vinylchloride reaches national health level index.
Description
Technical field
This utility model relates to polyvinyl chloride polymerization stripping operation device, and particularly a kind of stripper adds defoamer dress
Put.
Background technology
Polyvinyl chloride polymerization stripping requirements of process processes the slurry from blow tank, is carried out by heat exchanger slurry out
After heat exchange, enter stripper top, the hot water from stripping hot-water cylinder enter each layer of column plate of stripper carry out with slurry mixing,
Heating, strips the Vinyl Chloride Monomer in slurry from recovered overhead to gas holder；Slurry is through stripping discharging transport pump to slurry tank.From
Vinyl Chloride Monomer and the steam on stripper top together escape, through overhead condenser, tower top complete condenser by water vapor condensation extremely
Waste water tank, and Vinyl Chloride Monomer enters stripping vapor-liquid separation tank through stripping vacuum pump, the water separated follows through gas vacuum
Ring pump is outer row after entering cooler, and not solidifying vinyl chloride gas is then delivered to recovery system and reclaims.And stripper has eight layers, eight
Layer tower tray easily produces foam, causes tower tray buildup to block stripper, and affects steam stripped stable operation, at system operation
The buildup of stripper is carried out by middle needs, is so unfavorable for that production process effectively removes the vinyl chloride in polyvinyl chloride pulp
Stable operation.
Utility model content
The purpose of this utility model is to provide a kind of stripper and adds defoamer device, and the use of this device avoids stripper
Eight layers of tower tray buildup and affect steam stripped stable operation, effectively avoid stripper putty, decrease cleaning stripper simultaneously
The frequency, improve the stable operation index of stripper in PVC Production Process；Also can guarantee that stripper effectively removes poly-
Vinyl chloride in vinyl chloride slurry, it is ensured that in sold resin, content of vinylchloride reaches national health level index.
The purpose of this utility model is realized by following technical proposals.
A kind of stripper adds defoamer device, including stripper, and is communicated to the slurry feeding line of stripper and disappears
Infusion charge line, described slurry feeding line is communicated to eight layers of tower tray of stripper, and described defoamer charge line is communicated to
Eight layers of tower tray top of stripper.
Preferably, described slurry feeding line is by entering mashing pump connection slurry pool.
Preferably, described defoamer charge line connects defoamer storage tank by dosing pump.
Preferably, described defoamer storage tank is provided with defoamer loading hopper.
Preferably, it is provided with control ball valve between described defoamer reservoir outlet and dosing pump.
Preferably, the defoamer charge line at the eight layers of tower tray top being communicated to stripper is provided with into infusion valve.
Compared with prior art, this utility model has the beneficial effects that: this utility model stripper adds defoamer device, can
The foam that stripper eight layers charging layer produces is controlled, it is to avoid the foam that stripper charging layer produces blocks up tower or impact with effective
Removing vinyl chloride, it is ensured that stripper stable operation and resin vinyl-chloride-containing index can reach national health level index.
Accompanying drawing explanation
Fig. 1 is that stripper adds defoamer structural representation.
In figure: 1, defoamer storage tank；2, defoamer loading hopper；3, ball valve is controlled；4, dosing pump；5, defoamer charge pipe
Line；6, infusion valve is entered；7, stripper；8, slurry feeding line；9, mashing pump is entered.
Detailed description of the invention
With embodiment, this utility model is described further below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of stripper of the present utility model adds defoamer device, including stripper 7, and it is communicated to vapour
The slurry feeding line 8 of stripper and defoamer charge line 5, slurry feeding line 8 is communicated to eight layers of tower tray of stripper, froth breaking
Agent charge line 5 is communicated to eight layers of tower tray top of stripper.
Wherein, slurry feeding line 8 connects slurry pool by entering mashing pump 9, and defoamer charge line 5 is by dosing pump 4
Connection defoamer storage tank 1, defoamer storage tank 1 is provided with defoamer loading hopper 2, between defoamer storage tank 1 discharging opening and dosing pump 4
Being provided with control ball valve 3, the defoamer charge line 5 at the eight layers of tower tray top being communicated to stripper is provided with into infusion valve 6.
During use, the defoamer shipped is stored in an about 0.5m3Normal pressure (to sky) storage tank in, storage tank and dosing pump lead to
The stainless steel tube crossing DN15 connects, and pipeline adds the Valve controlling pump inlet of a DN15, and dosing pump will disappear by constant flow
Infusion joins at eight layers of feeding line of stripper top.Fall into the defoamer in tower and slurry that eight layers of feeding line is come in
Mix at eight layers of tower tray, be effectively controlled stripper due to charging layer produce foam and cause stripper putty,
Flooding or foam enter tower top vacuum lines, and the vacuum pipeline caused blocks or the phenomenon of vacuum pump locking.The most also
Vinyl chloride in the removing slurry that the stripper that enables is more stable.
Above content is to combine concrete preferred implementation further detailed description of the utility model, it is impossible to
Assert that detailed description of the invention of the present utility model is only limitted to this, for this utility model person of an ordinary skill in the technical field
For, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, all should be considered as
Belong to the scope of patent protection that this utility model is determined by the claims submitted to.
