Abstract
The invention discloses a process for recovering rosin and turpentine oil from a rosin package bag, which comprises the following steps of: separating an inner bag from an outer bag in the rosin package bag and suspending the inner bag and the outer bag on bag hanging rods; horizontally placing the bag hanging rods on a lug boss opposite to the inner wall of a bag steaming pot; conveying high-pressure steam with the pressure of 8-9g to the bag steaming pot; separating the turpentine oil from the rosin; enabling gaseous turpentine oil and water steam to enter a cooler together; after cooling, separating and recovering the gaseous turpentine oil from the water steam through an oil-water separator to recover the turpentine oil; and recovering the rosin. The process disclosed by the invention is simple, easy for operation and strong in pertinency and is specially designed for recovering the rosin on the rosin package bag; the discarded rosin package bag can be recovered and can be cleanly steamed; the turpentine oil and inferior resin have high recovery rate; in the process, a pure physical method is adopted and no chemical agent is added, and thus greenness and environment friendliness are achieved, resources are saved, the cost of enterprises is reduced and the pollution to the environment is avoided; and the process has favorable social benefit and economic benefit.
Description
Technical field
The invention belongs to the industrial technology field, be specifically related to a kind ofly in the course of processing of rosin, reclaim rosin and terebinthine technique from rosin packaging bag.
Background technology
Rosin can be processed into rosin and turps, and rosin has protection against the tide, anticorrosion, insulation, emulsification, the performance such as bonding, is a kind of important industrial chemicals, is widely used in the industrial trades such as papermaking, paint, medicine, printing and dyeing, coating, weaving; Turps is a kind of ethereal oil, is widely used in the industry such as paint, process hides, pharmaceutically is being used as antitoxin, cutaneous stimulant etc., also can spices processed.The source of this raw material of rosin is very limited, pine tree is cut down, the market heavy demand causes the reasons such as resin tapping is excessive, trees are dead, so that the price of rosin is more and more higher, processing rosin and terebinthine cost day by day go up, and in numerous rosin source mill, effectively reclaim technique and equipment owing to lack, rosin packaging bag is after finishing its packed and transported task, namely be dropped, in fact, because rosin has viscosity, a lot of rosin is also boning on these rosin packaging bags, simply abandoned, not only wasted resource, also caused environmental pollution.
Summary of the invention

In order to solve the above technical problem, the present invention is a kind of to reclaim rosin and terebinthine technique from rosin packaging bag, and described technique may further comprise the steps:
I, cleaning rosin packaging bag: the rosin packaging bag inner bag is separated with outer bag, be hanging on the hanging bag bar;
II, boiling rosin packaging bag: the hanging bag bar level load that will hang rosin packaging bag is placed on steams on the relative boss of bag pot inwall, transfer pressure is the high pressure steam of 8-9kg in the bag pot to steaming, pot inner pressure is controlled in the 0.2MPa, and boiling separated turps more than one hour with rosin;
III, turps cooling are reclaimed: vaporous turps enters water cooler with water vapor, and cooling is by water-and-oil separator Separation and Recovery turps;
IV, rosin reclaim.
As preferably, in the step II of the present invention, describedly entered the steam hole ejection boiling rosin packaging bag on the pot internal steam pipe by an admission opening that steams bag the bottom of a pan sidewall to steaming the steam of carrying in the bag pot; In the described step III, the water-cooled tube of described water cooler and turpentine oil pipe are level and replace spiral arrangement, water coolant water inlet, water outlet direction respectively with turps oil-feed, fuel-displaced opposite direction, the water temperature that enters cooling tube is not higher than 40 ℃, the water temperature of discharging cooling tube is not higher than 80 ℃.
The present invention reclaims rosin and terebinthine technique from rosin packaging bag, its used steaming bag pot, admission opening is arranged on a pot body hypomere sidewall, and the pot inner bottom part is provided with the vapour pipe in carrying vapour hole, be connected through the steam pipeline of admission opening with the outside, be provided with in opposite directions boss on the pot inner side-wall.Technique concrete operation method of the present invention is: before (1) steams bag, the inside and outside bag of rosin packaging bag is separated, be hanging on the hanging bag bar, the hanging bag bar level load that will hang again rosin packaging bag is placed on steams on the relative boss of bag pot inwall, shut pot door and induced exhaust valve, open outage valve and admission opening valve, transfer pressure is the high pressure steam of 8-9kg in the bag pot to steaming, pot inner pressure is controlled in the 0.2MPa, and rosin packaging bag is carried out high temperature steaming; (2) in digestion process, the vaporous oil that produces and water vapor are from the outage oil-drain pipe of flowing through, flow to the turpentine oil pipe of water cooler, the water-cooled tube of water cooler and turpentine oil pipe are level and replace spiral arrangement, the water coolant water inlet, the water outlet direction respectively with the turps oil-feed, fuel-displaced opposite direction, the water temperature that enters cooling tube is not higher than 40 ℃, the water temperature of discharging cooling tube is not higher than 80 ℃, liquefy through the cooled turps of supercooler and water vapor, mix and together enter water-and-oil separator, the principle different according to profit proportion will be in the turps of epimere and the water of hypomere and separate, and reclaim turps; (3) boiling is more than one hour, the rosin that bonds in the packing bag has basically become turps and has been evaporated discharge, remaining is loose slag and inferior rosin, drops to the bottom of a pan, and boiling finishes, close the admission opening valve and cut off steam, close the outage valve, open the induced exhaust valve and ventilate, open the pot door, packing bag after inferior rosin, loose slag and the boiling is taken out, and inferior rosin can continue to process Korean pine perfume (or spice).
Beneficial effect of the present invention: technique of the present invention is simple, and operation is with strong points easily, for the rosin that reclaims on the rosin packaging bag designs, the rosin packaging bag that is dropped is reclaimed specially, the packing bag boiling is clean, turps and the inferior rosin rate of recovery are high, adopt pure physical method, do not add any chemical reagent, environmental protection, both economized on resources, reduce enterprise cost, free from environmental pollution again, have good Social benefit and economic benefit.
