Problems solved by technology

However, the traditional bamboo fiber production technology still adopts the softening method of soaking in alkaline pools. It takes 7-10 days for bamboo chips to soften and decompose, and a large amount of sewage is produced, resulting in low output, serious pollution, and high sewage treatment costs. ...

Abstract

The invention provides a digester and a technology for quick softening and decomposition of bamboos, and relates to the technical field of production of natural bamboo fibers. The digester comprises amain steam pressure container; the lower end of the main steam pressure container is fixedly mounted on a channel steel base; electric heaters are mounted between the channel steel base and the mainsteam pressure container; a rotating platform is mounted in the center of the inner bottom surface of the main steam pressure container; a top sealing cover is mounted at the upper end of the main steam pressure container; a pressure gauge and a thermometer are arranged on the top sealing cover; a self-controlled thermometer is mounted on the side wall of the main steam pressure container; and a pressure reducer is arranged on the left side of the main steam pressure container. According to the digester and the technology, bamboo chips are contained in a cage and sent into the digester, and collagen sugar lignin is decomposed and softened quickly under the effect of certain pressure and high temperature; compared with a traditional method for soaking with a sodium hydroxide solution, the technology has the advantages that the efficiency of the technology is increased by 160 times, the production efficiency is substantially improved, the wastewater yield and the waste water treatment cost are reduced, and the technology is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of bamboo raw fiber production, in particular to a digester and process for rapidly softening and decomposing bamboo. Background technique [0002] Bamboo raw fiber is a renewable resource, and bamboo can be harvested and utilized after 1 to 2 years of growth. Moreover, bamboo fiber is currently a healthy natural plant fiber that absorbs and releases moisture. [0003] At present, the market application of bamboo fiber is relatively mature and has a wide range of applications. For example: bed core pads, automotive interior panels, architectural decorative panels, sound insulation panels, moisture-proof carpets, antibacterial insoles, shoe soles, sanitary products, spinning, weaving fabrics, ecological restoration felt pads, etc. trillion yuan market. However, the traditional bamboo fiber production technology still adopts the softening method of soaking in alkaline pools. It takes 7-10 days for bamboo ch...
