Description
Technical field
The present invention relates to the molten medicine device of a kind of polyacrylamide, can solve polyacrylamide occurs due to conglomeration in being dissolved in the process of water " flake " problem.
Background technology
Polyacrylamide (cpolyacrylamids) is called for short PAM, be by acrylamide (AM) monomer through the water-soluble linear high molecular polymer that free radical polymerization forms, be insoluble to most of organic solvents.Polyacrylamide is white powder or fine granularity thing, and density is 1.32g/cm3 (23 degree), and vitrification point is 188 degree, and softening temperature is bordering on 210 degree.
Polyacrylamide has good flocculability, can reduce the frictional resistance between liquid, can be used as the drag reducer of effective flocculant, thickener, paper strengthening agent and liquid etc., be widely used in the industrial departments such as water treatment, papermaking, oil, coal, mining and metallurgy, geology, light textile, building.
PAM is widely used as presence agent, filter aid, all spends agent etc. in field of papermaking.Its effect is the quality that can improve paper, improves the de-watering of slurries performance, improves the retention of fiber fines and filler, reduces raw-material consumption and to the pollution of environment etc.PAM is used in papermaking effect depends on the activity of its mean molecule quantity, ionic nature, ionic strength and other copolymer.Nonionic PAM is mainly used in improving the filter of paper pulp, increases dry paper intensity, improves the retention of fiber and filler; Anionic copolymer is mainly as the wet reinforcing agent of doing of paper and presence agent; Cationic copolymer is mainly used in paper waste and processes and filtrating aid function, for the retention that improves filler, effect is preferably also arranged in addition.In addition, PAM also is applied to paper waste processing and fiber recovery.
Polyacrylamide generally all needed to be mixed with the dilute solution of 0.1 %～0.5% before using standby.Polyacrylamide fully dissolving just can be given full play to flocculation.
The dissolving method of existing polyacrylamide is generally that PAM is joined in the dissolving tank with mixing plant, by the mode that the limit edged stirs, makes PAM form colloidal liquid.In the water-soluble solution process of polyacrylamide, often there will be bulk floc sedimentation and " flake " phenomenon, this " group " is difficult to dissolve, and can affect to a great extent the flocculating function of polyacrylamide, causes waste, also easily causes pipeline obstruction.In order to alleviate this phenomenon, extending mixing time is one of mode commonly used at present.Although extend mixing time, can dissolve to a certain extent these established agglomerates, can destroy simultaneously the long-chain of polyacrylamide, molecular chain rupture occur, and lose the peculiar function of PAM.
Summary of the invention
In order to solve above-mentioned defect of the prior art, the invention provides a kind of molten medicine device that polyacrylamide is fully dissolved, can solve polyacrylamide occurs due to conglomeration in being dissolved in the process of water " flake " problem.
In order to realize above-mentioned technical purpose, the present invention has adopted following technical scheme:
The molten medicine device of a kind of polyacrylamide, is characterized in that, described molten medicine device comprises:
Metering dry powder chemicals feeder for quantitative dosing;
Pre-wetted cylinder body for pre-wetted and preliminarily solubilised polyacrylamide dry powder;
For polyacrylamide after mixing water and pre-wetted and the mixed liquor injection is entered to the medicine dissolving device of pipeline; With
With the storage polyacrylamide solution and with the storage bin of agitating device;
Metering dry powder chemicals feeder is connected with water inlet pipe, is located at the top of pre-wetted cylinder body; Described medicine dissolving device is injector, is arranged on the connecting line between pre-wetted cylinder body and storage bin, and is connected with high-pressure hydraulic pump.
Further, described pre-wetted cylinder body is provided with the liquid level monitoring probe, can accurately control the amount of water in cylinder body.
Described medicine dissolving device has a press water import, a resin solution import and a mixture export; The press water import is connected with high-pressure hydraulic pump, and the resin solution import is connected with pre-wetted cylinder body below pipeline, mixture export connecting conveying pipe road, and transfer pipeline is connected with storage bin.
Metering dry powder chemicals feeder, with self-measuring device, can mill polypropylene in amine dry powder and quantitatively be added to the pre-wetted cylinder body.The pre-wetted cylinder body is equipped with water in advance, for pre-wetted and preliminarily solubilised polyacrylamide dry powder, can adopt the materials such as plastics, enamel, aluminium or stainless steel.Medicine dissolving device is injector, and after water under high pressure and pre-wetted, polyacrylamide fully mixes therein, and mixed liquor sprays via nozzle, out enters in transfer pipeline afterwards from mixture export.The jet blower bore of medicine dissolving device is adjustable, can need to regulate according to difference, and in the present invention, the jet blower bore is preferably 15.5-20.5mm, and storage bin is with the stirring at low speed device, for further dissolving and the storage polyacrylamide solution.
At first Polyacrylamide Powder is quantitatively joined in the pre-wetted cylinder body of water by metering dry powder chemicals feeder, tentatively dissolves in the pre-wetted cylinder body, then from the resin solution import, enters into medicine dissolving device.Medicine dissolving device relies on water under high pressure, and the negative pressure that the high velocity stream formed through nozzle produces sucks the pre-wetted polyacrylamide, in hybrid chamber, mixes, and sprays and enter pipeline from mixture export.Bulk floc sedimentation and " flake ", through mixing and the jet-action of medicine dissolving device, are fully smashed and are dissolved, and polyacrylamide solution finally is conveyed into storage bin by conveyance conduit.
The solution prepared should not be crossed long storage time, should adopt stirring at low speed in storage bin.
The present invention has following characteristics:
(1) can avoid the generation of bulk floc sedimentation and " flake ", polyacrylamide is fully dissolved, content is even in water, to give full play to its various functions.
(2) dissolution velocity is fast, and efficiency is high, can polyacrylamide be dissolved fully, is conducive to increase economic benefit, economizes on resources.
