Abstract
The invention relates to a method for processing primary rosin by middle layer grease liquid, which comprises the following steps of: firstly adding the middle layer grease liquid into a dissolving kettle; adding turpentine until the content reaches 35 to 40 percent; adding 0.5 to 1 percent of decolorizing agents; heating the middle layer grease liquid to a temperature being 92 to 98 DEG C through steam; injecting materials to a high-position pot to carry out oil-water separation; filling the separated middle layer grease liquid to a secondary clarification pot for carrying out clarification; firstly carrying out primary vacuum filtering and secondary nanometer filtering on the clarified middle layer grease liquid; filtering impurities in the middle layer grease liquid and adsorbing substances with dark color on the decolorizing agents; finally carrying out vacuum distillation finally carrying out vacuum distillation at the temperature being 140 to 160 DEG C and with the vacuum degree of 20 to 30mm water column for about 25 minutes. The released rosin reaches the primary rosin standard. The method provided by the invention has the advantages that the middle layer grease liquid is directly used for producing the primary rosin, the production process is simple, the turpentine does not need to be washed, the water consumption and the waste water quantity are reduced, the produced rosin has stable quality, and each index reaches the first-grade product standard.
Description
Technical field
The present invention relates to the rosin working method, relate in particular to a kind of middle level fat liquid processing one-level rosiny method.
Background technology
Rosin adds man-hour, in clarifying process, one deck fat liquid is arranged between clarified resin liquid and the water layer, water is called middle level fat liquid with the brown mixture that impurity mixes mutually, middle level fat liquid contains 30-40% rosin, the turps of 15-20%, 35-40% water, other impurity of 1-5%, because middle level fat liquid foreign matter content is more, conventional method of producing can only be produced black rosin, and rosiny is a bit darkish in color, the foreign matter content height, the rosin deciding grade and level is off-specification material.
Summary of the invention
The technical problem to be solved in the present invention provides middle level fat liquid to be processed as one-level rosiny method.
Technical scheme of the present invention is: at first middle level fat liquid is joined in the dissolution kettle, add turps to its content 35-40%, add the 0.5-1% discoloring agent, be heated to temperature 92-98 ℃ with open steam then; Make extremely high-order pot after heating finishes and carry out oily water separation, the middle level fat liquid after the separation enters the secondary clarifying kettle and clarifies, and clarifying temperature will maintain 86-96 ℃, and the middle level fat liquid after the clarification carries out the one-level vacuum filtration earlier, and vacuum tightness maintains the 50-80mm water column.Filtering material 600 orders-800 order carries out the secondary micron again through the filtering middle level of one-level fat liquid and filters, and vacuum tightness is at the 40-70mm water column, and temperature is at 85-96 ℃; Impurity in the fat liquid of filtering middle level and be adsorbed on saturate material on the discoloring agent carries out vacuum distilling, distillation temperature 140-160 ℃ at last; Vacuum tightness 20-30mm water column, about 25 minutes of distillation time, the rosin of emitting reaches the one-level rosin standards.
Advantage of the present invention is: directly by middle level fat liquid production one-level rosin, production technique is simple, need not wash rosin, reduces the consumption and the wastewater flow rate of water, and the rosin quality of producing is stable, and every index reaches the first grade standard.
Description of drawings
Fig. 1 is a process flow sheet of the present invention.
In the drawings 1, middle level fat liquid 2, condenser 3, hopper 4, dissolving oil groove 5, water scale tank 6, dissolution kettle 7, high-order pot 8, grade one filter 9, clarifying kettle 10, put fragrant groove 11, secondary filter 12, still pot 13, sub-cylinder 14, condenser 15, visor 16, vacuum buffer tank 17 vacuum pumps 18, transfer oil drum 19, pump 20, water-and-oil separator.
Specific implementation method
As shown in Figure 1, middle level fat liquid (1) adds 0.2 ~ 1% discoloring agent through hopper (3) and is incorporated into dissolving pan (6), adds turps content to 35-40% according to ratio from dissolving oil groove (4), and adds suitable water according to practical situation from scale tank (5); To dissolution kettle (6), the dissolved temperature is controlled at 92-98 ℃ to turps gas in the system of emptying by the laggard material bin of condenser (2) condensation (3); About 10 minutes of time, after dissolving finishes middle level fat hydraulic pressure to high-order pot (7) is tentatively carried out oily water separation, carrying out 800 order filter materials through grade one filter (8) then filters, then further clarify to clarifying kettle (9), clarification finishes to enter secondary filter (11) and carries out the micron filtration, removes impurity, enters still pot (12) at last, the still pot heat-conducting oil heating adds the open steam that is come by sub-cylinder (13) simultaneously; Turps steam enters water-and-oil separator (20) by vacuum pump (17) by vacuum buffer tank (16) and visor (15) and condenser (14) and separates in the distillation, isolates turps to transfer oil drum (18), gets to the turps storage tank by pump (19) again; 140-170 ℃ of the temperature control of still pot; Vacuum tightness 20-30mm water column, about 25 minutes of distillation time; The rosin that comes out in the bottom arrives first puts fragrant groove (10), forms one-level rosin at last and carries out finished product packing.
