Aerobe degumming reaction system for hemp fibers

Abstract

The invention discloses an aerobe degumming reaction system for hemp fibers, and relates to the technical field of hemp fiber degumming. The aerobe degumming reaction system comprises an efficient aerobe fluidized bed reactor, a middle buffering pool, a hemp fiber aerobe degumming tank and a control system. One side of the lower portion of the efficient aerobe fluidized bed reactor is provided with a first feeding pipe and an aeration pipe, the other side of the lower portion of the efficient aerobe fluidized bed reactor is provided with a second feeding pipe, the middle of the efficient aerobe fluidized bed reactor is provided with a reaction area, the upper portion of the reaction area is provided with a mud pipe, and the top of the reaction area is provided with a third water outlet; the middle buffering pool comprises a water inlet and a mud outlet; the hemp fiber aerobe degumming tank is provided with a water distribution area and a degumming area from bottom to top in sequence, wherein the water distribution area is provided with a water inlet pipe, an air inlet pipe and a microporous aeration disc, one side of the upper portion of the degumming area is provided with a firstwater outlet, and the other side of the upper portion of the degumming area is provided with a second water outlet; besides, the hemp fiber aerobe degumming tank is provided with a heat preservation layer, a hot water inlet and a hot water outlet. The system is easy to operate and control, microbe degumming for the hemp fibers is achieved, the problem that degumming wastewater is hard to treat isalso solved, and the system achieves nearly zero discharge, is environmentally friendly, and has a good application prospect.

Description

technical field [0001] The invention relates to a hemp fiber aerobic biological degumming reaction system, which belongs to the technical field of hemp fiber degumming. Background technique [0002] my country is the world's largest flax spinning country, the world's largest producer, consumer and exporter of textiles and clothing, and its textile and clothing exports account for more than 35% of the world's total. In the past five years, the total investment of my country's textile industry along the "Belt and Road" accounted for about 10% of the global textile investment in the same period. More than 80% of the total. Hemp fiber textile raw material has always been favored by people. Hemp fiber refers to the fiber obtained from various hemp plants (including ramie, jute, hemp, flax, apocynum, etc.). Compared with other fibers, hemp fiber has good functions of moisture absorption and dehumidification and air permeability, fast heat transfer, cool and crisp. [0003] The h...
