Embodiment 1

[0028] A kind of energy-saving rosin processing method, such as figure 1 ,Specific steps are as follows:

[0029] (1) crushing: the bulk rosin obtained is crushed by a crusher, so that the particle diameter of the rosin is between 30-50 millimeters to accelerate subsequent dissolving;

[0030] (2) Cleaning: use turpentine and water as a mixture of 1:20 to clean the turpentine particles to reduce the impurity content on the surface of the turpentine;

[0031] (3) Dissolution: transport the turpentine into the melting pot, and feed the high-temperature tail gas and oil gas of 90-100 ° C released at the bottom of the melting pot to dissolve the turpentine in the dissolving liquid in the dissolving pot, wherein the dissolving liquid is added The weight of the turpentine is 40% of the weight of the pine resin, and the dissolving solution includes the following components by weight: 40 parts of water, 30 parts of turpentine and 0.3 part of oxalic acid;

[0032] (4) Clarification: ...

Embodiment 2

[0035] A kind of energy-saving rosin processing method, such as figure 1 ,Specific steps are as follows:

[0036] (1) crushing: the bulk rosin obtained is crushed by a crusher, so that the particle diameter of the rosin is between 60-80 millimeters to accelerate subsequent dissolution;

[0037] (2) Cleaning: use turpentine and water as a mixture of 1:30 to clean the turpentine particles to reduce the impurity content on the surface of the turpentine;

[0038] (3) Dissolution: transport the turpentine into the melting pot, and feed the high-temperature tail gas and oil gas of 90-100 ° C released at the bottom of the melting pot to dissolve the turpentine in the dissolving liquid in the dissolving pot, wherein the dissolving liquid is added The weight of the pine resin is 40% of the weight of the pine resin, and the dissolving solution includes the following components by weight: 30 parts of water, 20 parts of turpentine and 0.1 part of oxalic acid;

Abstract

The invention disclsoes an energy-saving rosin processing method, and belongs to the technical field of production of rosin. The method comprises: crushing and washing rosin particles; putting the rosin particles into a melting pot for melting; putting melted rosin liquid into a high-level pot and a clarifying pot for clarifying; putting the clarified rosin liquid into a pre-heating rosin storage pot for pre-heating; putting the pre-heated rosin into a continuous distillation pot for distilling, wherein heat for pre-heating the rosin liquid before melting and distillation is obtained from high-temperature tail gas and oil gas, which are released through distillation, and heat needed by distilling comprises steam from a boiler, superheated steam from a heating furnace and heat which is absorbed and raised through a heat pump. By adopting the energy-saving rosin processing method, the high-temperature tail gas and the oil gas in the distillation pot are recycled, and the heat pump, namely a heat raising device, is arranged in a distillation process, so that the heat of surrounding air in a processing process is sufficiently utilized; when the heat pump is used, hot air temperature needed by the boiler and the heating furnace is also reduced, so that fuel consumed by the boiler and the heating furnace is reduced, and the aim of saving energy is realized.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of rosin production, in particular to an energy-saving rosin processing method. [0003] 【Background technique】 [0004] Pine resin is a resin secreted by pine tree trunks, which belongs to the product of tree physiological activities, and is viscous or massive solid in the air. The economic value of direct utilization of rosin is low, but rosin is rich in rosin and turpentine. Rosin and turpentine are widely used chemical basic raw materials. Among them, rosin is insoluble in water and has anti-corrosion, insulation, bonding, softening and other properties. It is the main raw material of synthetic rubber, paint, soap, emulsifier, paper and other chemical products. Turpentine is a colorless or light yellow volatile oil, widely used in paint, leather and other industries. Therefore, processing rosin can not only provide the country with a large amount of industrial raw materials and export materials...
