Abstract
The invention discloses a treatment device for pressing alkali. The treatment device for the pressing alkali comprises a pressing alkali tank, a liquid supply pump I, a tubular filter I, a buffer tank, a liquid supply pump II, a tubular filter II, a pressurizing pump and a safety filter. A recovering method for the treated pressing alkali comprises the following steps of: step a, injecting the pressing alkali into the tubular filter I through the liquid supply pump I, intercepting greater semi-fibers by a filtering element and enabling alkali liquor to enter the next-stage buffer tank; step b, enabling the alkali liquor subjected to primary separation to enter the tubular filter II for further separating semi-fiber impurities; and step c, pressurizing the alkali liquor and removing fine particles in the alkali liquor by the safety filter so as to ensure the quality the alkali liquor at an outlet. According to the treatment device disclosed by the invention, on the principle of not changing the properties of original alkali liquor, the current treating device for the pressing alkali is improved and intensified for overcoming the defects; and by optimizing a treatment process of the traditional device, the complete device is compact in structure, effective separation of the semi-fibers from the alkali liquor is realized and the pressing alkali liquor is recovered efficiently and economically.
Description
Technical field
The present invention relates to a kind of viscose industry alkali steeping pressed liquor treating apparatus and recovery method.
Background technology
Viscose is the artificial fibre of realizing the earliest suitability for industrialized production, and over more than 100 year, viscose is because its comfortable performance is subject to consumer's favor for a long time.Viscose more and more is subject to application industry and consumers in general's favor with its complete kind, good characteristic, and its range of application has expanded to the every field such as clothes, decoration, health care and industry articles for use from conventional industries.In production process of viscose fiber, the hemicellulose in the raw material need to be dissolved out with aqueous slkali by dipping, otherwise production technology and end product quality are produced extremely adverse influence.And can produce the high concentration alkali that contains half fibre in the dipping process, because quantity of alkali consumption is large, need to remove half again reuse of fine impurity.China mainly adopts dialysis to separate half fibre, reclaims squeezing alkali, but dialysis technique reclaims the alkali inefficiency, and water consumption is large, and investment is higher.
Summary of the invention
The purpose of this invention is to provide that a kind of alkali treatment efficient is high, compact conformation and economic and practical squeezing alkali treatment device and recovery method.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of squeezing alkali treatment device comprises squeezing alkali tank, solution feed pump I, tubular filter I, surge tank, solution feed pump II, tubular filter II, force (forcing) pump, security personnel's filter.The outlet of described squeezing alkali tank connects the entrance of solution feed pump I; The entrance of the outlet connecting pipe formula filter I of described solution feed pump I; The outlet of described tubular filter I connects the entrance of surge tank; The outlet of described surge tank connects the entrance of solution feed pump II; The entrance of the outlet connecting pipe formula filter II of described solution feed pump II; The outlet of described tubular filter II connects the entrance of force (forcing) pump; Described pressurization delivery side of pump connects the entrance of security personnel's filter.
A kind of recovery method that squeezes alkali treatment may further comprise the steps:
Step a, squeezing alkali injects the tubular filter I through the solution feed pump I, and half larger fibre is filtered the element interception, and alkali lye enters the next stage surge tank;
Step b, alkali lye entered the tubular filter II through the solution feed pump II after one-level was separated, and further separated half fine impurity;
Step c by security personnel's filter, removes fine particle in the alkali lye after the force (forcing) pump pressurization, guarantee outlet alkali lye quality.
The present invention is not changing original alkali lye character in principle, the defective that exists for present squeezing alkali treatment device and weakness are improved and are strengthened, by optimizing the treatment process of existing apparatus, the package unit compact conformation, realize the effective separation of half fibre and alkali lye, the recovery press lye of high-efficiency and economic.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments.
Fig. 1 is the process chart that the present invention squeezes the alkali treatment device.
The specific embodiment
As shown in Figure 1, specific embodiments of the invention, mainly may further comprise the steps: squeezing alkali injects the tubular filter I through the solution feed pump I, separate half fibre more than 20～35 microns, the one-level separation enters the tubular filter II by the solution feed pump II, further separates 10 microns with first fine impurity, passes through security personnel's filter after the force (forcing) pump pressurization, remove 5 microns with first fibre, package unit more than 5 microns treatment effeciency can reach more than 95%.
