Efficient environment-friendly straw prepared cotton and cotton preparation method

Abstract

The invention relates to efficient environment-friendly straw prepared cotton and a cotton preparation method. Cotton is major economic crops in farm products in China; large-area cultivated land, pesticide and labor are used for cotton planting; in a conventional straw cotton preparation method, waste water, waste gas and waste slag often occur; the environment is polluted. The efficient environment-friendly straw prepared cotton and the cotton preparation method are characterized in that the method comprises the following steps of (1) straw twisting and softening (by a purpose-made automatic twisting machine) and fragment processing: collecting straw fragments accumulated every day; screening the straw fragments by an automatic screening machine; conveying the straw fragments greater than 50mm to a first alkalization pool to be used as production raw materials; using generated powder for water-logged compost; (2) alkalization; (3) water washing; (4) acidification; (5) bleaching; (6) ustulation; (7) weight checking and warehouse entering. The method provided by the invention belongs to a method applied to cotton preparation from straw.

Description

technical field [0001] The invention relates to a fine utilization of rice straw, a by-product of harvested crops, and provides an efficient and environment-friendly rice straw production method and a cotton production method. Background technique [0002] my country is a large agricultural country, with rice planting area of ​​more than 600 million mu, and a large number of by-products - rice straws are produced every year. Due to the lack of attention to the processing of agricultural products in the past and the lack of corresponding processing equipment, a large amount of rice straw was wasted, and even a large part was burned in the rice fields, which not only wasted resources, but also polluted the atmosphere. Cotton has a wide range of uses. In addition to making cotton clothes, it is also used as an important industrial raw material in large quantities, which requires a large amount of cotton. Therefore, cotton has become the largest economic crop in my country's agr...

Problems solved by technology

Due to the lack of attention paid to the processing of agricultural products in the past and the lack of corresponding processing equipment, a large amount of rice straw was wasted, and even a large part was burned in the rice field, which not only wasted resources, but also polluted the atmosphere.

Cotton has a wide range of uses. In addition to making cotton clothes, it is also used as an important industrial raw material in large quantities, which requires a large amount of cotton. Therefore, cotton has become the largest economic crop in my country's agricultural products. The cultivation of cotton has occupied a large area of ​​arable land, pesticides and Manpower, while the traditional rice straw cotton method often has waste water, waste gas and waste residues, which pollutes the environment
