Bio-enzyme decomposition method fiber separation equipment and system thereof

Technical Field

The invention relates to the field of biological enzyme decomposition, in particular to a fiber separation device and a fiber separation system by a biological enzyme decomposition method.

Background

China is a big agricultural country, and with the development of agricultural production, the grain yield is greatly improved since the 80 s in the 20 th century in China. The straw is a general term of stem and leaf parts of mature crops, generally refers to the residual parts of wheat, rice, corn, potatoes, rape, cotton, sugarcane and other crops (generally coarse grain) after seeds are harvested, is rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, and is a multipurpose renewable biological resource. The use of modern chemical fertilizers greatly reduces the agricultural requirements on the fertilizers made from straws, and the treatment of the straws becomes a difficult problem. If the straws are not processed in time, the sowing of the sowed crops can be influenced.

Several kinds of straw treatment methods exist in the prior art, and all have the problems of environmental pollution and low efficiency: (1) and (5) burning the straws. Smoke generated by burning straws causes the reduction of air visibility, and directly influences the normal operation of roads, civil aviation, railways and other traffic; (2) plant fibers such as straws are used as raw materials, and a chemical pulping method is adopted for papermaking. The sewage discharged by the chemical pulping method contains a large amount of harmful substances such as COD, BOD, SS and the like, and seriously pollutes a water source; (3) some low efficiency, simple physical comprehensive utilization. Such as: as building materials; agricultural products such as straw hats, straw mats and the like are prepared, but the demand of the purposes is far less than the yield of straws every year, and the problem of treating a large amount of straws cannot be fundamentally solved.

In the prior art, the straw is treated by a chemical and biological compound pulping process aiming at the condition that the straw is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matters, and the paper is made by using a paper pulp raw material. Because the process is compounded with a chemical pulping process, the problems of wastewater pollution and poor quality of produced paper pulp still exist, so that the environment-friendly and sustainable pulping technology which can be used for industrialized large-scale mass production and can separate high-end paper pulp by using field waste straws is urgently needed to be realized at present. For the technical problem of pulping, the pulping technology of 'biological enzyme decomposition and separation of fiber' is researched at home and abroad, but the industrial mass production of paper pulp capable of realizing 'biological enzyme decomposition and separation of fiber' is still unavailable up to now. The difficulty of realizing industrial mass production of paper pulp by 'decomposing and separating fiber by biological enzyme' is as follows: (1) the process requirement is very complex, and the working procedures are many; (2) the process conditions are very high. Biological bacteria and enzyme preparations have particularly high requirements on the activity conditions; (3) the difficulty of the straw fiber stripping technology is high, so that the large-scale temperature control and pH value regulation and control of the straw fiber are difficult to carry out.

The Chinese patent application 201911153952.6 proposes a fiber separation device by a biological enzyme decomposition method, which can meet the process requirements of the pulping process of 'biological enzyme decomposition and separation of fibers' in the aspects of temperature control, reactant addition, pH value control, pressure control and the like. However, the application adopts a single separation device to complete all processing technologies, so that the overall efficiency is low, and the large-scale popularization cannot be realized.
