Abstract
The invention discloses a turpentine partial condensation tower which comprises a cylinder of which the upper end is provided with an upper end socket and the lower end is provided with a bottom plate, wherein a discharge opening is formed in the top of the upper end socket; the interior of the discharge opening is filled with a packing; the middle in the cylinder is filled with the packing by virtue of grids; a spray pipe which extends out of the cylinder is arranged on the upper part in the cylinder; and a feeding hole is formed in the lower part of the cylinder. Compared with the prior art, the turpentine partial condensation tower disclosed by the invention has the advantages that the consumption of cooling water is high and the purity is low during conventional gum rosin production can be solved.
Description
Technical field
The present invention relates to rosin deep processing equipment technical field, especially a kind of for terebinthine partial condensation tower.
Background technology
Existing turps method of cooling is called spiral-plate heat exchanger method of cooling.Current China gum resin complete processing has continous way steam distillation and intermittent type steam distillation etc., in rosin production process, extracts all kinds of oil content by control distilling material temperature and distillation time.Wherein excellent oil component boiling point is minimum, as long as temperature of charge controls just most α-pinene and beta-pinene to be steamed out below 155 DEG C, then through spiral-plate heat exchanger, plate-type heat exchanger, oil content is cooled down, be separated through water-and-oil separator, salt filter again, the excellent oil of purity at about 70%-85% can be obtained.Spiral plate condenser take water as refrigerant, high temperature oil content and steam can well be cooled down.Mixing liquid, after being separated, obtains the processed oil that purity is higher.Seemingly, temperature of charge steams two class oil contents respectively between 155-190 DEG C, is switched by three-way valve for the separation method of middle oil and heavy oil and excellent oil phase.Switching point is as the criterion with heavy oil diene (α-pinene and beta-pinene) content≤2%, and stable production process can determine switching point by observation distillation gas phase temperature and distillation time (middle oil and heavy oil distillation time about 25min altogether).By spiral-plate heat exchanger, plate-type heat exchanger, water-and-oil separator, salt filter, finally can obtain the comparatively stable middle oil of quality and heavy oil, middle oil part is used as rosin dissolving oil and circulates in systems in which, and part can be made processed oil and sell, and heavy oil is then direct to be sold as processed oil.Concrete operations are: put into by the fat liquid measured and melt pot, and add appropriate hot water and oxalic acid, with steam as heating medium, fat liquid is heated to 95 DEG C, be sent in clarifying kettle and clarify layering after rosin melts completely; Clarification operation: after multiple clarifying kettle (the more clarifying effects of clarifying kettle are better), filters fat liquid, and put into pressure fat tank, 0.1Mpa pressure distills to one-level still pot.One-level distillation process: control distilling material temperature≤160 DEG C, gas phase temperature≤155 DEG C, the α-pinene of the overwhelming majority and beta-pinene are distilled, high-temperature oil gas first through spiral-plate heat exchanger, then through plate-type heat exchanger, is cooled to less than 35 DEG C, enter oil-water separation system, the oil separated again through salt filter, out be qualified processed oil, beat to oil tank.Secondary distillation operation: after one-level distillation terminates, high-temperature material is put into secondary distillation pot, improve temperature of charge further, the kautschin of the inside and longifolene etc. are steamed (≤190 DEG C), refrigerated separation respectively, stores respectively.The barrelling of the finished product rosin stores.
There are following two subject matters in existing oil gas cooling system: 1. need to consume a large amount of water coolants, energy consumption is large.After spiral-plate heat exchanger, plate-type heat exchanger, temperature of charge is reduced to about 25 DEG C to high temperature oil content (100 DEG C ~ 190 DEG C), and wherein need a large amount of service waters as heat-eliminating medium, energy consumption is larger.2. gained processed oil purity is not high, and excellent oily diene content is about 78%, and deep processing will through purifying.
Summary of the invention
Problem to be solved by this invention is to provide a kind of turps partial condensation tower, expends cooling water inflow greatly, the problem that purification degree is not high to solve the cooling of existing turps.
In order to solve the problem, technical scheme of the present invention is: this turps partial condensation tower comprises upper end and is provided with the cylindrical shell that upper cover lower end is provided with base plate, and the top of described upper cover has discharge port, is provided with filler in described discharge port; Middle part in described cylindrical shell is provided with filler by grid, and the top in described cylindrical shell is provided with the shower stretching out described cylindrical shell, and the bottom of described cylindrical shell is provided with opening for feed.
In technique scheme, more specifically scheme can be: be respectively provided with a visor outside the upper and lower of described cylindrical shell, and described upper cover is provided with gas phase temperature meter, and described cylindrical shell bottom is provided with liquid-phase outlet and liquid thermometer.
Further: described filler is steel wire ripple packing.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, in oil gas process for cooling, the fractional condenser of our factory's designed, designed is added before spiral-plate heat exchanger, i.e. this turps partial condensation tower, separating effect is significantly improved, the terebinthine quality of excellent one-level has had obvious improvement, be increased to more than 82% from original α-pinene and beta-pinene content about 78%, good raising effect is played in the application for derived product;
2, through this gum resin partial condensation tower, the oil gas that boiling point is higher, is beating in reflux course, because temperature reduces suddenly, so be condensate in bottom this turps partial condensation tower, directly form liquid oils, plate-type heat exchanger can be back to and cool further, middle oil is called after oily water separation, between the general 20-40% of diene content, circulate in systems in which as melting oil, the utilization ratio of water coolant improves greatly, save energy, decreases discharge of wastewater.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail:
This turps partial condensation tower as shown in Figure 1, it comprises upper end and is provided with the cylindrical shell 1 that upper cover 10 and lower end are provided with base plate 12, and the top of upper cover 1 has discharge port 9, is provided with filler 9 in discharge port 9 by grid, here filler 9 is scum dredger, can flow out the oil gas that temperature is high.Middle part in cylindrical shell 1 is provided with filler 6 by grid 5, and filler 6 here and filler 9 are steel wire ripple packing.Top in cylindrical shell 1 is provided with the shower 7 stretching out cylindrical shell 1, stretches out the import that cylindrical shell 1 part is shower 7.The bottom of cylindrical shell 1 is provided with opening for feed 11; Like this, the oil gas that boiling point is higher, is beating in reflux course, because temperature reduces suddenly, so be condensate in bottom this gum resin partial condensation tower, directly forms liquid oils, can be back to plate-type heat exchanger and cool further.Respectively be provided with a visor 4 outside the upper and lower of cylindrical shell 1, conveniently observe internal-response.Upper cover 10 is provided with gas phase temperature meter 8, and cylindrical shell 1 bottom is provided with liquid-phase outlet 2 and liquid thermometer 3.Before this gum resin partial condensation tower is increased in spiral-plate heat exchanger, plays the effect of distribution condensation, improve the purity of product, saved and used water.
