Description

Technical Field

[0001] This invention relates to the field of floating oil rosin processing technology, specifically to a processing apparatus and method for producing high-viscosity floating oil rosin. Background Technology

[0002] Tall rosin, also known as tall oil rosin or rosin oil resin, is derived from the wood pulping and papermaking industry. It is obtained by processing black liquor recovered from sulfate pulping. Typically, rosin is esterified with polyols such as glycerol and pentaerythritol under high temperature and in the presence of a catalyst (usually 230°C–300°C) to obtain rosin resin. To improve esterification efficiency, the catalyst usually contains esterification catalysts. To reduce the color of the rosin resin, the catalyst usually also contains decolorizing catalysts, such as organosulfur compounds. Existing tall oil rosin processing methods still produce rosin with residual moisture, resulting in a lower viscosity.

[0003] The purification of floating rosin requires the use of vacuum distillation equipment. Existing vacuum distillation equipment includes distillers, condensers, recovery tanks, vacuum pumps, etc. Among them, there are various types of condensers, and the condensation effect of the condenser directly affects the quality of floating rosin. During the circulation of the cooling medium, when air enters the condenser, the gas tends to stick to the surface of the heat exchange capillary tube, affecting the condensation effect of floating rosin. Therefore, to address the above problems, a processing device and method for producing high-viscosity floating rosin are proposed. Summary of the Invention

[0004] The present invention aims to provide a processing apparatus and method for producing high-viscosity floating rosin. The processing apparatus includes a purification cylinder with an inner cylinder inside. A hollow cavity exists between the inner cylinder and the outer wall of the purification cylinder. When the burner head in the combustion base burns, the flame burns along the outer wall of the inner cylinder, accelerating the heating of the floating rosin inside. The air after combustion enters a filter cylinder, where a filter element filters the combustion exhaust gas, achieving a good environmental protection effect. The heat exchanger chamber in the processing apparatus has alternating lower and upper guide plates. A water guide groove is provided at the top of the lower guide plate and at the bottom of the upper guide plate. The top of the heat exchanger chamber is equipped with... The device features a vertically movable lifting plate that, when lowered, fits against the top of the upper guide plate. As the lifting plate rises, the cooling medium enters the heat exchange chamber and fills it sequentially from right to left. Due to the gap between the upper guide plate and the lifting plate, the cooling medium can fill the entire heat exchange chamber, expelling the air accumulated between the upper guide plates. The air exits through the outlet pipe at the top of the heat exchange chamber. When the cooling medium level rises to the middle of the outlet pipe, it flows back into the cooling tank through the return pipe, achieving circulation of the cooling medium. This heat exchanger exhibits excellent condensation performance and effectively prevents air accumulation within the heat exchanger, which would affect the condensation of floating rosin, thus solving the problems mentioned in the background art.

Due to the gap between the upper guide plate and the lifting plate, the cooling medium can fill the entire heat exchange chamber and discharge the air accumulated between the upper guide plates inside the heat exchange chamber to the outside of the heat exchange chamber. The air is discharged from the discharge pipe at the top of the heat exchange chamber. When the cooling medium level rises to the middle of the discharge pipe, it flows back into the cooling box from the return pipe, realizing the circulation of the cooling medium.

Inside the heat exchanger 4, from left to right, are an inlet chamber 401, a heat exchange chamber 402, and a discharge chamber 403. An exhaust pipe 14 extends into the inlet chamber 401. A heat exchange capillary tube penetrating the heat exchange chamber 402 is installed between the inlet chamber 401 and the discharge chamber 403. Inside the heat exchange chamber 402, a lower guide plate 404 and an upper guide plate 405 are alternately arranged.
