Problems solved by technology

This method is aimed at the processing of rosin residue, can reclaim a certain amount of turpentine and rosin from the residue of turpentine, but this invention does not realize residue recovery in rosin processing process simultaneously, and this invention does not carry out any pretreatment to raw material, although can reach A certain effect of increasing production, but still can not achieve the best effect
Therefore, in the process of rosin processing, the following problems need to be solved to improve the yield rate: (1) the impurity content of rosin is large, and the unstable parameters of the conventional processing process are difficult to control and are easily oxidized; (2) the residue of rosin processing contains certain rosin , the recycling process is complicated, and recycling alone will cause waste of resources

Embodiment 1

[0033] 1. Hypoxic sterile water treatment:

[0034] Take water treatment agent according to the weight ratio of water: superoxide: sodium dithionate: reduced iron powder: sodium chloride=85:3:5:4:3, add superoxide to tap water or industrial water after leaving standstill 2h, Continue to add sodium thionite powder to the water and let it stand for 30 minutes, then add reduced iron powder and sodium chloride powder in turn, let it stand for 22 hours, and extract the supernatant as hypoxic sterile water for later use.

[0035] 2. Rosin processing:

[0036]The raw material rosin is stored and transported with hypoxic sterile water, after the rosin is crushed, the rosin is soaked and rinsed with hypoxic sterile water, and the crushed rosin is transported to the dissolving pot by the conveyor for dissolving, and the rosin in the pot is dissolved. The heating steam comes from the surplus steam after distillation in the primary distillation pot and the secondary distillation pot. The...

Abstract

The invention relates to the field of pine resin processing and discloses a pine resin processing method with pine resin processing yield increased. The method includes the steps of pre-treatment, dissolution, water washing, clarification, residue recovery, distillation, and finish product collection. In the method, a raw material is pre-treated and is water-washed under supersonic wave; and during the dissolution, an internal heating coil is employed for heating the raw material, zeolite added to break the raw material; and meanwhile, through the residue recovery, vacuum distillation and the like, efficiency of pine resin processing is improved and yield of pine resin is increased. The method is free of big modification on devices and can achieve stable control, thereby achieving stable production and yield increasing.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of rosin processing, in particular to a rosin processing method for improving the yield of rosin processing. [0003] 【Background technique】 [0004] Rosin is an important industrial raw material, which is widely used in soap, paper, paint, pigment, rubber and other industries, and is also one of my country's bulk export commodities. The yield rate of rosin processed products is an important economic and technical indicator of rosin processing. The height of rate directly affects the economic benefit of factory, prior art thinks, the main factor that influences turpentine processing output rate has the quality of rosin raw material, impurity content is low, and the product output rate of rosin production with low oxidation rate will be higher, therefore, In order to improve the yield of rosin, the current rosin processing often strengthens the quality management of rosin, and rosin residue often contains a certa...
