High-efficiency energy-saving low-cost high-quality rosin production process and production line equipment

Abstract

The invention discloses a high-efficiency energy-saving low-cost high-quality rosin production process, which comprises the steps of: firstly carrying out turpentine impurity removal and liquification working procedure: firstly adding a little dissolving oil (5-10%) to turpentine, carrying out pressure filtration with a spiral filter press to remove main mechanical impurities in turpentine, heating refined turpentine at 50-70 DEG C, carrying out pressure filtration with a chamber filter press to further separate the mechanical impurities of turpentine, and inputting the purified turpentine liquid to a turpentine liquid storage tank; and then carrying out turpentine liquid distillation working procedure: inputting the purified turpentine liquid to a distillation tank, separating out rosin and turpentine oil, inputting the turpentine liquid with turpentine oil separated into a reaction kettle, carrying out reduced-pressure distillation to distill heavy turpentine oil, then keeping on heating to gasify the rosin liquid, condensing the rosin vapor into rosin liquid, and inputting to a rosin finished product storage tank. The production line equipment comprises the filter press, the turpentine liquid storage tank, the distillation tank, the reaction kettle, the rosin finished product storage tank, a heavy oil storage tank, a turpentine oil storage tank and a heavy turpentine oil storage tank.

Description

(1) Technical field: [0001] The invention relates to rosin production, in particular to a high-efficiency, energy-saving, low-cost, high-quality rosin production process and production line equipment thereof. (two) background technology: [0002] At present, the traditional rosin production process is to add rosin to dissolved oil, water and oxalic acid for heating and dissolving, then pour it into a high-level pot for slagging treatment, and then put the fat liquid into a clarification tank for clarification to further remove fine impurities and water. The clarified fat liquid is heated and distilled to separate the production process of turpentine and rosin. [0003] In the traditional rosin production process, equipment such as melting kettles (1-2), high-position pots (2-3), clarification tanks (4-5), transition tanks, and distillation pots (1-2) are required. There are auxiliary oil-water separators (3), oil-water metering tanks, filters, condensers (multiple), etc. A ...

Problems solved by technology

Due to many production links, problems often occur in the production process, which brings a lot of inconvenience to the production, and the quality of rosin is difficult to be guaranteed.

[0005] In addition, in the traditional rosin production process, a large amount of dissolved oil (generally 30% to 35%) and water (5% to 10%) are added to the dissolution and heated to 95°C to 100°C. During the entire clarification process, the temperature must be kept above 90°C, and the separation of...
