Cotton stalk phloem composite bio-enzyme aqueous solution biological degumming reaction kettle

Abstract

The invention provides a cotton stalk phloem composite bio-enzyme aqueous solution biological degumming reaction kettle. The cotton stalk phloem composite bio-enzyme aqueous solution biological degumming reaction kettle comprises a kettle body, wherein a kettle cover and a feeding port are formed in the top of the kettle body, and a water filling nozzle and an observation port are formed in the kettle cover; the lower part of the kettle body is provided with a heating pipe and a discharging port, a drain outlet is formed in the bottom of the kettle body, a return pipe is arranged on one side of the kettle body, and a temperature control sensor is arranged in the middle of the kettle body. The cotton stalk phloem composite bio-enzyme aqueous solution biological degumming reaction kettle is a process technology for biologically degumming cotton waste, namely cotton stalk phloem, removing lignin and the like and preparing textile process fibers by applying a biotechnology, conforms with the development tendency of low carbon economy and can expand into the degumming and preparation of biomass plant phloem fibers, and meanwhile, a process technical scheme for comprehensive development and utilization of cotton stalks in stead of wood is put forward in terms of energy source preparation and papermaking materials, so that the great economic benefits and the good social benefits are created.

Description

[0001] This application is a divisional application, the filing date of the original application is May 16, 2012, the application number is 201210150218.6, and the title of the invention is "Method for preparing cotton stalk bast textile fiber by biotechnology and degumming reaction kettle". technical field [0002] The invention relates to a biological degumming reaction kettle for cotton stalk bast composite biological enzyme aqueous solution. Background technique [0003] According to statistics, my country produces 6 million tons of lint per year, about 9 million tons of cotton stalks are produced by planting cotton, and the annual output of cotton stalk skins is about 5 million tons. However, cotton stalks, which are rich in resources and cheap in price, are generally discarded or burned, resulting in large losses. waste. For a long time, the bast of cotton stalks and cotton stalks have not been fully utilized as cotton by-products (waste) for fuel in rural areas. In re...

Problems solved by technology

In recent years, with the upsurge of environmental protection and deep utilization of natural resources, people have begun to increase the research on the development and utilization of cotton stalks. For example, Chinese patent CN1068866 discloses a method for pretreatment of cotton stalk fibers; Chinese patent CN1052484 Disclosed a process for the manufacture of nitrocellulose from cotton stalk; although they made a positive step in the utilization of cotton stalk, textile fibers suitable for textile use could not be produced by their method

In 1998, Shandong Heze invented the patent "Method of Extracting Textile Fiber from Cotton Stalk Skin"; in 2005, Liu Lei invented the patent "Cotton Stalk Skin Fiber and Its Processing Method" Chemical + Tanning Degumming; Tianwei Textile Technology (Shenzhen) Co., Ltd. applied for it in 2006 Chemical degumming patent, technological process: peeling → slag removal → degumming → health preservation → cutting → tanning → fiberizing → carding → separation → drying → binning and grading; 2009 Zhejiang University of Technology and Guangdong Esquel patent "a high-temperature low-alkali cotton rod Quick degumming method of leather fiber"; most of the patented technologies focus on chemical degumming, which is obviously not in line with the development of low-carbon economy, and lacks comprehensive utilization, and basically has not realized industrialization
