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 turpentine and rosin must be carried out during the distillation process, resulting in the repeated use of energy and a large amount of energy consumption

[0006] Aiming at the problems existing in the traditional rosin production process, rosin manufacturers have also carried out some process improvements, but the process improvements are limited to different degrees of modification on the existing equipment, and the overall process does not deviate from the principle of the traditional process
