A kind of cooling pulping method of biological agent of traditional Chinese medicine

Abstract

The invention provides a traditional Chinese medicine (TCM) biological agent cold pulping method comprising the following steps: (1) material preparing and soaking; (2) grinding and dividing: dividing and fibrillating softened pulping raw material into tobacco shred-like fibers; (3) residual water recycling: conveying pulp ground out by pulping equipment through a single-helix conveyor, and extracting residual chemical water through a double-helix press washer; (4) screening and slag removing: adding water to dilute the pulp in a transition pool and pumping the pulp to screening equipment, and pumping the pulp after screening to slag removing equipment to remove sand impurities; (5) washing and concentrating: inputting the pulp to dehydration equipment for dehydration, and then, adding bleaching agent and removal agent and entering a delignification and bleaching link; and (6) concentrating the pulp into finished pulp: further dehydrating and concentrating the pulp for using or selling. The method is non-toxic, bubble-free, odor-free and emission-free, and causes no pollution to the air and the environment. The pulp can be stored without changing color; the whiter the pulp is, the longer the pulp is stored; and the pulp does not go bad. Moreover, the method is simple in operation, can save electricity, water, equipment and manpower, and is low in cost.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a method for cooling and pulping traditional Chinese medicine biological agents. [0002] technical background [0003] At present, papermaking enterprises are restricted by the bottleneck of development, which mainly comes from the following reasons. One is the shortage of resources. It takes 10 to 15 years to grow each cubic meter of wood. The other is that too much felled wood is used for papermaking, which is not conducive to water and soil conservation. Natural disasters such as debris, sulfur, and sandstorms are common. It is closely related to the imbalance of soil and water conservation caused by excessive deforestation by people. The traditional papermaking process mostly uses strong alkali and strong acid cooking methods, and the discharge of "three wastes" will inevitably pollute the environment, which has attracted the attention of the government and relevant departments.

Problems solved by technology

However, due to the progress of society and the civilized life of human beings are inseparable from paper, the contradiction between supply and demand of paper products is prominent. With the development of paperless life, there is a disparity between supply and demand of paper products. While the demand is constantly increasing, it is shutting down, stopping, merging, and turning, so the market gap is constantly increasing, which brings many problems to people's lives. Inconvenient, the traditional thermal pulping and papermaking method must be boiled in a boiler, and the temperature is only 110 degrees. The pulp produced is black and yellow, and the water that comes out is black. The water consumption is large, and the cost of chemical treatment is high.

Although CN1626730 discloses the compound of the cooking agent ammonium sulfite and potassium hydroxide added, the cooking black liquor is used as N and K compound fertilizer after being properly treated; Disadvantages of high cost of potassium oxide

However, the thermal pulping method still has the disadvantages of strong odor, serious air pollution, and the produced pulp is not suitable for storage, and it will change color after a long time.
