Description
Technical field
The utility model relates to a kind of vacuum protector, the vacuum protector of the refining or vent gas treatment that abietic resin is produced of especially a kind of rosin.
Background technology
Rosin is a kind of widely used chemical industry base stock, generally is to be the product of raw material through obtaining after distilling with rosin.China's rosin output remains on 500,000～600,000 t/a always, estimates in 10～15 years from now on, and the relevant industry of China will show a rising trend to rosin and reprocessing product demand thereof.
Abietic resin be a kind of be raw material with rosin or modified rosin, under certain temperature condition, the common name of the one type of rosin that takes place that esterification obtains through carboxyl and alcohol or the derivative of modified rosin.
Rosin refining with the abietic resin production process in can produce a large amount of waste oil waste water; Generally all be these waste oil waste water to be removed or reclaimed through exhaust gas processing device; But it is very unstable to use device for recovering tail gas of the prior art to reclaim rosin waste oil waste gas; Destructive power to device is big, causes reduce greatly device lifetime, and cost improves greatly.
Summary of the invention
The utility model provides a kind of vacuum protector of vent gas treatment for overcoming above-mentioned defective, can be so that rosin waste oil waste water be stable, and the service life of improving device.
The utility model is realized through following technical scheme:
The vacuum protector of the refining or vent gas treatment that abietic resin is produced of a kind of rosin; Comprise vacuum buffer tank, condenser, vacuum filtration jar and vacuum unit; It is characterized in that at least one vacuum buffer tank directly links to each other with rosin refining kettle or abietic resin agitated reactor.
According to the utility model, in the said vacuum protector, outlet is arranged at the top of at least one vacuum buffer tank, and this outlet is connected with the condenser overhead inlet through pipeline.
On the bottom cylindrical shell of said condenser outlet is arranged, said outlet links to each other with the bottom inlet of vacuum filtration jar through pipeline.
According to the utility model, said vacuum buffer tank is preferably one or more.More preferably said vacuum buffer tank is 2-3.The purpose that a plurality of vacuum buffer tanks are set is to increase buffering effect, and controls flow velocity and flow better.
According to the utility model, said vacuum protector preferably has only a vacuum buffer tank, and the import of this vacuum buffer tank directly links to each other with the outlet of refining kettle or agitated reactor, and the outlet of vacuum buffer tank links to each other with the import of condenser.
According to the utility model, said vacuum protector has plural vacuum buffer tank, and wherein at least one vacuum buffer tank one end directly links to each other with refining kettle or agitated reactor, and the other end links to each other with condenser.More preferably, another vacuum buffer tank is arranged between vacuum filtration jar and the vacuum unit at least.
According to the utility model, on said vacuum buffer tank, vacuum meter is installed.In order to the vacuum in the measuring system.When showing that like vacuum meter vacuum is low (＜0.08mpa), that just means that revealing appears in system or the work of vavuum pump group is undesired, just need quit work, and vacuum system is overhauled.
According to the utility model, said condenser can be the conventional condenser of this area, like shell and tube condenser or spiral plate condenser, and preferred spiral plate condenser.Its heat exchange area is big and floor space is less relatively because the spiral plate condenser is.The whole welded closure in waste oil waste water tunnel two ends of said spiral plate condenser, condensation water channel two ends standard-sized sheet is with packing seal.
Owing to reasons such as this body structure and weld seams; The outlet highest level position of condensed water often is lower than the horizontal level of peak level in the condensation channel, and condenser passages is generally all longer, and the on-condensible gas in the water just is prone to productive set on condensation water channel top like this; Form " air chamber "; Hinder condensed water to carry out heat exchange, increased the suffered thermal stress and the influence of mechanical stress of " air chamber " scope inside weld, make it produce the be full of cracks leakage.In order to solve this technical problem, the utility model is above the condensation water channel of condenser, and the position near outlet pipe on the top cover installs the on-condensible gas bleeder pipe additional, is used for constantly discharging on-condensible gas in the condensation water channel.
According to the utility model, in said vacuum filtration jar, filler is housed.Said filler is Raschig ring, porcelain square saddle, porcelain arc saddle, the short Raschig ring of porcelain, plastics Pall ring, plastics cascade ring, metal Pall ring.More preferably, filler is a Raschig ring.The external diameter of the packing ring of Raschig ring with highly equate; Simple in structure; Inexpensive, because condenser has separated most of profit with oil water separator, make liquid presort cloth and the purpose that increases the liquid in the contact-making surface filtration vacuum pneumatic thereby use Raschig ring can satisfy fully.
According to the utility model,, can on the vacuum filtration jar, check valve be set in order to prevent the generation of suck-back phenomenon.
According to the utility model, the volume ratio of said vacuum buffer tank and condenser is 2-10, and preferred 2-5 more selects 2,3,4.
According to the utility model, outlet is all arranged at described vacuum buffer tank, condenser and vacuum filtration jar bottom.
The purpose that the utility model is provided with the vacuum unit is for gas clean-up.Because the strength of single vacuum machine is smaller, and if system's seal bad, vacuum is not enough.The vacuum unit is exactly with the use that is together in series of several vacuum machines.And when resin, very high to the vacuum requirement, just can't effectively carry out purification operations if vacuum is low to rosin.Under the condition of vacuum unit, rosin can become gaseous state about condition of high vacuum degree, 270 degree.The vacuum that the utility model vacuum unit reaches is 50～400Pa, just can obtain refining effect preferably.
The utility model directly links to each other vacuum buffer tank with refining kettle or agitated reactor, and it has following effect:
Because the vacuum buffer tank of the utility model is the cavity container; The vacuum unit with a kind of intermittence very short pulsed vacuumize; Vacuum buffer tank realizes that the stable of air pressure mainly is the cavity that leans on certain volume, can vacuumizing of this pulsed be stablized into a kind of lasting vacuum force.
Simultaneously, the utility model vacuum buffer tank is arranged on the front of condenser, can play the effect of preliminary condensation.When refining the or abietic resin post processing of rosin vacuumized, the water vapour gas of the high temperate zone oil of extraction was when the container that enters into a sudden enlargement (vacuum buffer tank), after flow velocity lowers; Trickle drop will sink and separates with gas phase in the gas phase; At the bottom of part condensation converged in jar, uncooled gas got into condenser, and this can reduce the burden of condenser effectively; Prolong the service life of condenser, reduce cost.
In addition, the vacuum buffer tank of the utility model can be in jar adjustments of gas flow and flow velocity, make oil gas get into condensing unit with more stable fluidised form.Adopt the vacuum protector of the utility model, can realize following technique effect:
1, keep the vavuum pump group to the stable vacuum and the speed of exhaust of system's output;
2, fully with in the rosin subtractive process and the tail gas condensation of abietic resin filter out, get into the vavuum pump group and be unlikely to tail gas, cause the vavuum pump group to damage;
3, reduce the gas temperature that gets into the vavuum pump group, the cooling oil of Roots vaccum pump makes its unlikely emulsification or decomposition in the protection vavuum pump group;
4, through this cover vacuum protection system, the harmful part in the tail gas is removed clean, make it be unlikely to finally to get in the water ring pump of vacuum unit, one protects that water ring pump is unlikely to be corroded, and two guarantee that the water that water ring pump used is clean, can reuse.
