System and method for recovering natural fiber crystallized and modified gaseous phase medium on basis of multi-bus and multi-modification reactor parallel operation

Abstract

The invention provides a system for recovering a natural fiber crystallized and modified gaseous phase medium on basis of multi-bus and multi-modification reactor parallel operation. The system comprises a vacuum bus, a gaseous phase medium compression bus, n modification reactors which are connected to the vacuum bus and the gaseous phase medium compression bus in parallel, vacuum branches which are connected onto the vacuum bus in parallel, a first-level compression branch which is connected onto the gaseous phase medium compression bus in parallel, a second-level compression branch which is connected onto the first-level compression branch in series and a plurality of valves, wherein n is not less than 1. The invention further provides a method for recovering the natural fiber crystallized and modified gaseous phase medium on basis of multi-bus and multi-modification reactor parallel operation. The method comprises natural recovering, first-level compression recovering, medium vacuumizing and first-level compression recovering and second-level compression recovering. By the system and method, the modified medium is completely recovered, efficiently condensed and circularly used, so that a non-pollution and zero emission modifying process is realized, energy is saved and consumption is reduced; and the system and the method have the advantages that a set of medium recovering equipment serves a plurality of modification reactors, the modification reactors operate in parallel, the utilization rate and production efficiency of the equipment are increased, the equipment cost and the production cost are lowered.

Description

technical field [0001] The present invention relates to a recovery system and method for natural fiber crystal modification modified gas phase medium, in particular to a recovery system and method for natural fiber crystal modification modified gas phase medium based on multi-bus and multi-modification kettles in parallel, which belongs to high-end textile equipment field. Background technique [0002] Natural fiber is an important textile raw material. It has excellent properties such as moisture absorption and heat dissipation, anti-bacteria and insect resistance, and anti-radiation. However, it also has defects such as hardness, wrinkling, shrinkage, difficulty in spinning, weaving, and dyeing. Use crystal modification technology to modify natural fibers, so that while retaining the advantages, the performance is significantly improved, and the effects of easy spinning, easy weaving and easy dyeing are achieved, which not only improves the added value of natural fibers, b...
