Abstract
The invention relates to a preparation method for multi-functional high-efficiency flocculating agents, comprising the following steps: acrylamide, dimethyl cyclosiloxane, sodium carbonate, carbamide and de-ionized water which are selected are prepared according to the proportion, and are input to a batching tank by a centrifugal pump and are dissolved for forming the mixture, and then the mixture is transported to a polymeric kettle by the centrifugal pump, and then high-purity nitrogen is input from the bottom part of the polymeric kettle, evocating agents are added from a ball valve at the top part of the polymeric kettle, nitrogen is input for 15 minutes and then is stopped inputting, and the ball valve is closed at the top part of the polymeric kettle, so as to lead the mixture to be polymerized and to form colloid, 80 DEG.C of hot water is added to a kicked of the polymeric kettle, hydrolysis is carried out to the colloid for four hours, compressed air is used for compressing the material, dispersants are added at the same time, a pelletizer is used for pelleting, and then double-plastid vibration is carried out, a drier is used for frying, and the dried flocculating agents are packaged according to the granularity required by costumers for forming finished products. The preparation method is widely applied to industries such as industrial solid and liquid separation, sewage disposal, paper making, petroleum, petroleum, petroleum, geology, geology, buildings, packing industry, sugar refining, liquor making, etc.
Description
Technical field
The present invention relates to the preparation method that a kind of multifunctional efficient flocculation agent is produced, particularly relate to industries such as being mainly used in industrial solid-liquid separation, sewage disposal, papermaking, oil, coal, mining and metallurgy, geology, light textile, building, bridge.
Background technology
Along with China's rapid economy development, urban industry water and city's domestic use of water constantly increase, and the sewage of supervening is also increasing, in Shanghai, show according to relevant data, the sewage works in Shanghai just has 1,700,000 tons of sewage to enter every day, as 1% of the sludge content in the sewage, then just has every day 10,007 kiloton mud to need to handle, so, the province and even the whole nation need the sewage of treatment and purification every day, and sludge quantity will be a surprising number.Defectives such as the method for in the past disposing of sewage is to adopt the low cationic acrylamide powder-like product of one's share of expenses for a joint undertaking amount in some, and the product structure unicity, and technology is comparatively backward, and consumption is big aspect disposing of sewage, and dissolution rate is slow, and stability is low, and flocculation desliming efficient is low.
Summary of the invention
The purpose of this invention is to provide the preparation method that improved a kind of multifunctional efficient flocculation agent is produced, employing be non-ionic type, a kind of multifunctional efficient flocculation agent of anionic and cationic bonded.It can make sewage sludge obtain dissolving, separation, desliming rapidly efficiently, for paper industry, has the multifunctional efficient effect in the industry sewage disposals such as food-processing industry, petrochemical industry, dyeing, sugaring.
Technical scheme of the present invention is achieved in that selects acrylamide 920kg for use, dimethyl cyclosiloxane 100kg, and yellow soda ash 160kg, urea 50kg, deionized water 2770kg is equipped with ratio as starting material.The preparation concrete grammar is: import the 2770kg deionized water with impeller pump in material-compound tank; then with acrylamide 920kg; dimethyl cyclosiloxane 100kg; yellow soda ash 160kg, urea 50kg progressively is dissolved in the deionized water; it is dissolved fully; form blended stock, with impeller pump compound is delivered to polymeric kettle again, feed high pure nitrogen from the polymeric kettle bottom then; add initiator from polymeric kettle top ball valve simultaneously; after the initiator interpolation finishes, behind the logical 15 minutes nitrogen, stop nitrogen then and close polymeric kettle top ball valve; make the compound polymerization; after the compound polymerization finishes, form colloid, in jacket of polymerization, squeeze into 80 degrees centigrade of hot water and circulate; colloid was hydrolyzed 4 hours; after hydrolysis finishes, use the pressurized air binder, add dispersion agent simultaneously; carry out granulation by tablets press; enter two system mass vibratings then, drying machine carries out drying, the flocculation agent that drying is good; granularity according to customer requirement is carried out abrasive dust, is finished product after packing.
Because the present invention has done substantial improvement aspect starting material and the preparation method selecting for use, what adopt is non-ionic type, anionic and the cationic a kind of multifunctional efficient flocculation agent environmentfriendly products that combine and generate, thereby make flocculation agent can make industrial solid-liquid separation thorough, solid-liquid sedimentation, separation, clarification, concentrate and sludge dewatering aspect play multi-function action, bring actively useful social effect to sewage disposal with to paper industry, food-processing industry, petrochemical industry, the wastewater treatment of controlling gold, ore dressing, dyeing and sugar industry.
