Pine gum processing method and equipment

Abstract

The invention discloses a processing technology of turpentine by a steaming process and the device. The invention adopts the technology that the turpentine is previously preheated and then dissolved, the dissolved turpentine enters into the clearing procedure after adopting the transitional clearing step, the turpentine liquid is preheated after being filtered, then oil gas and colophony are distilled out, turpentine oil is obtained through the condensation of the oil gas, and the distilled high-temperature tail gas and oil gas are recovered to preheat the turpentine and the turpentine liquid; the device adopts that a turpentine preheating pot is arranged in front of a liquating pot; a transitional clarifying kettle is arranged before a clarifying kettle; a distilling and preheating pot is arranged between a turpentine liquid filter and a distillatory kettle. Compared with the prior discontinuous process technology, the processing technology can greatly increase the production, the quality of the colophony is greatly improved, more than 98 percent of the colophony can reach the special grade and the first-grade, the distilling degree of the top grade turpentine reaches 97 percent, half of the standard coal consumed by one ton of colophony is approximately saved, half of the steam and the cooling water are also reduced, and the energy saving and consumption reducing effects are remarkable.

Description

technical field [0001] The invention belongs to the field of rosin processing, and in particular relates to a process and equipment for steam processing rosin. Background technique [0002] Gum rosin and turpentine are widely used basic chemical raw materials. According to data, it is expected that China's rosin output will remain at 500,000-600,000 t / a for a long time in the future. In the next 10-15 years, China's relevant industries will The demand for reprocessed products of rosin and turpentine will show an increasing trend. [0003] Gum rosin has a special aroma, is insoluble in water, has anti-corrosion, insulation, bonding, softening and other properties, and is the main raw material for various light chemical products such as papermaking, synthetic rubber, paint, ink, soap, emulsifier, lubricant, etc. It can also be used for edible purposes such as chewing gum. Turpentine is an accompanying product when rosin is processed with turpentine. Generally, one ton of tu...

Problems solved by technology

But the main disadvantage is that it does not make full use of the tail gas of the steam in the distillation process, the heat temperature of oil and gas, the waste of heat energy is serious, and the loss is large.

And in the purification process, failure to solve the problem of liquid swirl caused serious waste of fat liquid and low total yield
