Abstract
The invention discloses a purification treatment device and a method for viscose before being spun. The purification treatment device for the viscose before being spun comprises a preheater, a feed liquid pump, a pipe type filter, a rinsing tank, a nitrogen storage tank and a waste viscose groove. The purification treatment method for the viscose before being spun comprises steps of preheating, filtering, rinsing, backwashing and deslagging. According to the purification treatment device and the method for the viscose before being spun, improvement and reinforcement are performed aiming at disadvantages and weaknesses of the existing purification treatment device for the viscose before being spun based on the principle that viscose components are not changed, the structure is compact and the filtering accuracy is high due to the facts that the treatment technology of the existing device is optimized and the integral device adopts a pipe type filtering element, and the filtering element regeneration efficiency is good due to a dual resining mode through the cleaning fluid and the compressed gas.
Description
Technical field
The present invention relates to a kind of purification separation technology, particularly a kind of viscose and spin front filtration, purification treating apparatus and method.
Background technology
Viscose belongs to regenerated celulose fibre, is taking native cellulose as raw material, and the soluble cellulose sulphonic acid ester of making through operations such as alkalization, aging, sulfonation is made viscose glue after diluted alkaline dissolves, and makes through wet spinning.In viscose solution after dissolving, contain a large amount of particulates, in spinning process, easily block spinneret orifice, affect spinning machine and normally move, therefore, viscose filtration need to be removed to granulometric impurity wherein.At present, viscose glue at least needs to filter through twice before spinning operation, all adopts KKF filter, and floor space is large, and backwash frequency is high, and filter screen regeneration difficulty, need frequently change.
Summary of the invention
The object of this invention is to provide a kind of floor space is little, filter core regeneration efficiency the is high front viscose glue purifying processing device of spinning and method.
To achieve these goals, technical scheme of the present invention is as follows:
Viscose glue purifying processing device before a kind of spinning, comprises pre-heater, solution feed pump, tubular filter, rinse bath, nitrogen storage tank, scrap rubber groove.Described filter is provided with tracing thermal-insulating device, prevents that viscose glue from condensing.Described pre-heater outlet connects the viscose glue import of solution feed pump; The viscose glue outlet of described solution feed pump connects the import of filter viscose glue; The clean liquid outlet of viscose glue of described filter connects next stage spinning machine spinning entrance; Described rinse bath outlet is connected with the filter washing water inlet of filter; The gas vent of described nitrogen storage tank is connected with the gas feed of filter.
Described tubular filter adopts the powder sintered filter core of high-precision metal, 1 micron of filtering accuracy.
A method for viscose glue purified treatment before spinning, comprises the following steps:
Step a, preheats: pending viscose glue is warming up to design temperature through pre-heater;
Step b, filters: viscose glue enters tubular filter through solution feed pump pressurization, and element separates granulometric impurity wherein after filtration;
Step c, cleans: after filtration finishes, pass into the residual viscose glue in cleaning fluid dissolving tank;
Steps d, backwash: pass into compressed nitrogen and will tackle at filter element surface and intrapore granulometric impurity stripping;
Step e, deslagging: impurity mixing cleaning fluid is through slag-drip opening discharge filter.
The invention has the beneficial effects as follows, do not changing viscose glue composition in principle, the defect and the weakness that exist for viscose glue purifying processing device before current spinning are improved and strengthen, by optimizing the treatment process of existing apparatus, package unit adopts tube filtering element, compact conformation, and filtering accuracy is high, adopt cleaning fluid and the dual cleaning model of Compressed Gas, filter core regeneration efficiency is good.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Fig. 1 is the process chart that before spinning of the present invention, viscose glue purifies coarse grain device.
Detailed description of the invention
As shown in Figure 1, specific embodiments of the invention, mainly comprise the following steps: viscose glue is warming up to 80～90 DEG C through pre-heater, pending viscose glue after heating enters tubular filter through solution feed pump pressurization, element separates granulometric impurity wherein after filtration, in filter process, pass through filter tracing thermal-insulating device constant temperature to 80～90 DEG C, after viscose filtration finishes, pass into the residual viscose glue in cleaning fluid dissolving tank, soak 1～2 hour, after immersion finishes, passing into compressed nitrogen will tackle at filter element surface and intrapore granulometric impurity stripping, impurity mixing cleaning fluid is through slag-drip opening discharge filter.
