Abstract
The invention provides a processing method of rosin and belongs to the technical field of preparation of chemical materials. The processing method of rosin is realized by virtue of the following technical scheme comprising the steps: (1) enabling the rosin to enter a continuous melting device, adding a certain parts of turpentine and water and introducing opening steam when the rosin is molten, wherein the temperature is controlled at 90-95 DEG C, filtering the molten rosin liquid by virtue of a filtration device arranged inside the melting device and enabling the molten rosin liquid to enter a continuous clarification tank; (2) clarifying the molten rosin liquid in the clarification tank for 6-8 hours so that the rosin liquid and water are automatically layered; and (3) preheating the clarified rosin liquid to 140 DEG C, feeding the preheated clarified rosin into a distillation tower, leading a mixed gas of turpentine steam and water vapor out of the tower top to a condenser, condensing, cooling, separating the moisture out by virtue of an oil-water separator and removing trace moisture from turpentine by virtue of a salt filter to obtain the finished product.
Description
Technical field
The invention belongs to industrial chemicals manufacture technology field, particularly relate to a kind of working method of rosin.
Background technology
Rosin is solid resin acid, and namely rosin is dissolved in the mixing solutions formed in terpenes liquid and turps.This mixing solutions does not have any economic worth, so the rosin contained in rosin and turps by processing, must be separated with distillating method, produce the rosin and turps that meet national regulation quality standard by rosin.Rosin and turps are important industrial chemicals, and many industrial sectors all will use it.Carry out pine gum processing, not only can provide a large amount of industrial raw material and outlet goods and materials to country, also can improve the standard of living of the mountain area people, prosperity mountain area economy.
Summary of the invention
The invention provides a kind of working method of rosin.The present invention is realized by following technical proposals:
(1) rosin enters continuous dissolver, adds turps and the moisture of certain deal when melting, and pass into opening steam when rosin melts, temperature controls at 90 ~ 95 DEG C, melts fat liquid after the filtration unit in dissolver, enters continuous clarifying tank;
(2) melt fat liquid to clarify at clarifying tank, fat liquid stops 6 ~ 8 hours wherein, makes fat liquid and water self exfoliation;
(3) the fat liquid clarified is preheated to 140 DEG C of feeding distillation towers, the mixed gas of turps steam and water vapour is drawn by tower top and is entered condenser, isolate moisture through water-and-oil separator after condensation and cooling, turps is removed after micro-moisture through salt filter and is finished product.
Embodiment
Below by specific embodiment, the present invention is further illustrated;
1, direct pyrogenic process
Direct pyrogenic process is directly loaded on rosin in still pot exactly, and the bottom of a pan is heated with directly making a fire, therefore is called direct pyrogenic process.Because this law is in still-process, when being heated to specified temperature, must proper amount of clear water being instilled, produce water vapor, reduce distillation temperature, steam turps, so directly pyrogenic process is also called the method for dripping;
2, steaming process
Steaming process makes processing thermal source with steam, and make working steam with superheated vapour, and namely steam sprays from the aperture of vapour pipe, to reduce distillation temperature, steams turps.
The steaming process of rosin adds work point three operations to carry out: namely rosin melts, melting fat liquid only makes and liquid processed distills only.If three operations are carried out all continuously, be called continuous processing; If three operations are all intermittently carried out, be then called interrupter method.But also some factory, some operation adopts the mode of production of continuous processing and other operations employing interrupter method.
Continuous steam method pine gum processing divides three operations to carry out, and its technical process is as follows:
1, rosin melts operation
Rosin worm conveyor squeezes into hopper by storing fat pond, continuous dissolver is entered through screw feeder, rosin is generally thickness and with the semi-fluid of certain moisture and impurity, for the ease of removing the conveying of impurity, need adds turps and the moisture of certain deal when melting.Rosin passes into opening steam when melting, and temperature controls at 90 ~ 95 DEG C, and the turps be evaporated in fusion processes and water vapour are reclaimed by the condenser on dissolver top.Melting fat liquid removes after thick impurity through the filtration unit in dissolver and enters continuous clarifying tank;
2, fat liquid operation processed is only melted
The component melting fat liquid comprises: rosin 47 ~ 49%, turps 27 ~ 30%, moisture 20 ~ 30%, impurity about 0.1%.Melt containing a large amount of moisture and fine impurities in fat liquid, China adopts fining process removing.Melt fat liquid to clarify at clarifying tank, the volume of clarifying tank is comparatively large, and fat liquid generally can be made to stop 6 ~ 8 hours wherein, make fat liquid and water self exfoliation, the fat liquid clean processed after clarification is sent to distillation process;
The water of clarifying tank effusion and terebinthine steam enter condenser and reclaim, and the slag-water slurry of bottom, is discharged by stable can.Middle-layer resin liquid clarifying tank is sent in the middle layer that moisture, fine impurities and a small amount of dark-coloured rosin are formed, and reclaims fat liquid wherein;
3, the distillation process of clean fat liquid processed
Distillation process carries out in continuous still battery tower.The fat liquid of clarification enters well heater by transition tank and is preheated to about 140 DEG C after spinner-type flowmeter mensuration flow, sends into distillation tower.Tower divides two sections, upper tower segment tower top steams light oil, the steam of light oil and the mixed gas of water vapour are drawn by tower top and are entered condenser, isolate moisture through the water-and-oil separator of excellent oil after condensation and cooling, light oil is sent into oil depot again and is finished product after salt filter removal micro-moisture.Lower tower section tower top steams heavy oil, releases rosin at the bottom of tower.Heavy oil is sent to oil depot through cool condenser, water-and-oil separator after being separated moisture.Packaging field barrelling delivered to by rosin after releasing.

(2) melt fat liquid to clarify at clarifying tank, fat liquid stops 6 ~ 8 hours wherein, makes fat liquid and water self exfoliation;
(3) the fat liquid clarified is preheated to 140 DEG C of feeding distillation towers, the mixed gas of turps steam and water vapour is drawn by tower top and is entered condenser, isolate moisture through water-and-oil separator after condensation and cooling, turps is removed after micro-moisture through salt filter and is finished product.
