Abstract
The utility model relates to a high-efficient acid bathing filter. The utility model comprises a main shell body and an outer shell which is composed of an upper sealing head and a lower sealing head, wherein the upper sealing head is connected with an acid outlet pipe and a degassing pipe, the acid outlet pipe and the degassing pipe are connected with a blowing pipe of air compression and a cleaning water pipe, and the lower sealing head is connected with an acid inlet pipe; the lower part of the main shell body is provided with an acid fouling opening, the upper end of the inner part of the main shell body is provided with a pattern plate, a plurality of vertical micropore filtering pipes are arranged on the pattern plate, and the micropore filtering pipe is composed of a micropore pipe of which the pipe wall is provided with a plurality of micropores, filtering cloth which is coated on the surface of the micropore pipe and a diatomite layer which is uniformly attached to the surface the filtering cloth. The utility model has the advantages of large filtering quantity, high filtering precision, less inverse cleaning time and good effect and can not result in secondary pollution.
Description
Technical field
The utility model relates to the filter technology field, particularly relates to a kind of acid bath filter.
Background technology
In the chemical fibre spinning is produced, cellulose xanthate in spinning bath and the viscose glue and yellow byproduct reaction, generate a large amount of colloid sulphur, these colloid sulphur have with tiny Dispersion of Particles in acid bath, the colloid of forming that has floats on the bath face, in addition, also bring a large amount of impurity in viscose glue or in the acid bath allocation process into, make spinning bath become muddy, increase the spinning fault, reduce end product quality, and these impurity also can be deposited on the wall, bring obstacle to production process, therefore must be equipped with the acid bath filter acid bath is filtered.Existing acid bath filter mainly contains quartz sand filtration device and millipore filter.The former filtration yield is little, and filtering accuracy is low, and the backwash cycle is short, the time spent is many; There is the defective that filtration yield is little, filtering accuracy is low equally in the latter, is not suitable for producing high-performance fiber, and equipment is huge, and it is many to take factory building, has a large amount of acid water during backwash and discharges, and environment is polluted.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, provides that a kind of filtration yield is big, filtering accuracy is high, the backwash cycle is long, few efficient acid bath filter of backwash time spent.
The efficient acid bath filter of the utility model, comprise by main casing and be connected upper cover on the main casing and shell that low head constitutes, the upper cover end face is provided with manhole, be connected with out acid tube and deaeration pipe on the upper cover, going out acid tube also is connected with the cleaning water pipe with the compressed air anti-blowpipe with deaeration pipe, be connected with acid inlet tube on the low head, the bottom of main casing is provided with dirty acid mouth.Interior upper end at main casing is installed with card, many vertical microfiltration tubes are installed on the card, microfiltration tube by tube wall have some micropores microporous pipe, be coated on the filter cloth on microporous pipe surface and evenly constitute attached to the diatomite layer on filter cloth surface.
Efficient as mentioned above acid bath filter, the micropore size on its microporous pipe is the 15-40 order.
Efficient as mentioned above acid bath filter, its diatomaceous particle diameter that forms diatomite layer is the 50-400 order.
Because the utility model forms a diatomite pre-filtering layer on the surface of microfiltration tube, and little, the adhesion in diatomite particle gap, increased the filter table area, strengthened the retaining power of filter medium, the rate of filtration and filtration yield under the condition that does not increase filtration resistance, have been improved, the filtering accuracy height.Because filtrate goes out on advancing under being when filtering, impurity segments cloth attached to slightly going up less, down on many under being on the microfiltration tube, blow under in the pipe by compressed air during backwash, impurity comes off rapidly under the effect of own wt and air-flow vibrations, the backwash time spent is few, effective, substantially do not wash with water, avoided secondary pollution.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
The specific embodiment
The accompanying drawing illustrated embodiment the utlity model has the shell of sealing, and shell is by columnar main casing 6, constitute by sending out the blue low head 19 that is connected the upper cover 3 of main casing 6 upper ends and is connected main casing 6 lower ends.Upper cover 3 end faces are provided with the manhole 2 that is used to check, are connected with out acid tube 1 and deaeration pipe 12 on the upper cover 3, go out acid tube 1 and also are connected with cleaning water pipe 11 with compressed air anti-blowpipe 10 with deaeration pipe 12.On low head 19, be connected with acid inlet tube 20 and alkali inlet tube 9, and be fixed with support.Be connected with the positive blowpipe 5 of compressed air on the top of main casing 6, the bottom is provided with dirty acid mouth 8, and Pressure gauge 13 and visor 14 are equipped with in main casing 6 sides.Also be fixed with hanger 7 in main casing 6 sides.Have in the inner chamber of main casing 6 upper end by sending out hard-wired card 4 blue, be installed with many vertical microfiltration tubes 15 on the card 4, microfiltration tube 15 comprises that tube wall has the microporous pipe 16 that some pore sizes are 15-40 order micropore, be coated with one deck filter cloth 17 on the surface of microporous pipe 16, filter cloth 17 surfaces evenly are attached with one deck diatomite layer 18, and the diatomaceous particle size that constitutes diatomite layer 18 is the 50-400 order.During filtration, acid bath is advanced from acid inlet tube 20, goes out from going out acid tube 1, and constantly injects the diatomite turbid liquid betwixt.During backwash, the direct compressed air that enters by compressed air anti-blowpipe 10 is removed filter cake to microfiltration tube 15 blowbacks.For prolonging 15 service lifes of microfiltration tube, blowback repeatedly back adds the low concentration soda baths from alkali inlet tube 9 microfiltration tube 15 is regenerated, during just blowing repeatedly by the positive blowpipe 5 of compressed air, to improve regeneration effect.
