Pulp & Paper Industry
Pulp and Paper Industry needs a lot of water to produce paper. Only with the help of pulp water suspension, can the paper obtain its uniform structure. No matter for the treatment of primary fibers (such as wood and pulp), or the recycling of waste paper, enormous water is needed. At the same time, a large number of generated wastewater needs to be well treated. In addition, the recycling of waste paper, and the treatment of pigments require mechanical separation equipment. RS decanter centrifuge and disc stack separator are widely adopted in wastewater treatment, waste paper recycling, pigment extraction and so on.
Polyvinyl Chloride & Polyethylene Industry
Polyvinyl chloride (PVC) is a starting agent for vinyl chloride monomers in peroxides, azo compounds, etc.; or it is a polymer polymerized under the mechanism of free radical polymerization under the action of light or heat. PVC is widely used in building
materials, industrial products, daily necessities, flooring leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers and so on. Most PVCs are produced by suspension polymerization. In the suspension polymerization process, RS decanter centrifuge can be well used to dehydrate the polymerized
Dehydration Of Pure Alkali, White Mud, Salt Mud
The treatment of white mud and salt mud has always been a difficult problem in ammonia alkali soda producing enterprises. It is impossible to treat the white mud and salt mud by landfill, so it is necessary to make 100% comprehensive utilization of them. The white mud and salt mud treated by decanter centrifuge do not need sand separation process, which is different from the process requirements of plate-frame filter press. The sand in the normal distilled waste liquid can be separated by the decanter centrifuge, and it will not affect the equipment.
Separation and extraction of APIs (active pharmaceutical ingredient), pharmaceutical intermediates, teas, honeysuckles, Chinese yews, vitamin B5, porcine brain protein, intestinal capsid, etc. API extraction process: net preparation, cutting, processing, drying, crushing, extraction (water extraction or solvent extraction: organic solvents such as ethanol), solid-liquid separation, ultra-filtration, evaporation concentration (recovery of organic solvents), drying, crushing, screening, packaging, sending to the solid or liquid preparation workshop. In the solid-liquid separation process, RS C Series explosion-proof high-speed decanter
centrifuge or high-speed disc stack separator can be used to separate and remove impurities after alcohol precipitation to get the active ingredients dissolved in ethanol solution; followed by high-temperature distillation of ethanol and a complete separation of pharmaceutical ingredients.
Production of Chemical Products
In the chemical material processing engineering, RS decanter centrifuge and disc stack separator can be used to clarify the liquid, separate the two kinds of liquid with different densities, classify the solid mixture, and carry out the dehydration of the liquid-solid mixture. Common chemical materials are: aluminum hydroxide, barium sulfate, bauxite, saponite, calcium carbonate, calcium fluoride, calcium sulfate, carbonized sludge, sodium hydroxide, cellulose derivatives, clay mud, pigments, cryolite, dimethyl terephthalate, epoxy resin, fluorescent materials, graphite, gypsum, iron oxide, iron oxide, kaolin, latex, alumina, lead
sulfate, lime slurry, mica, mineral oil, nickel hydroxide, pharmaceutical intermediates, phosphoric acid products, phosphoric acid, plastic derivatives, polymethyl methacrylate, polypropylene, calcium silicate, sodium chloride, titanium dioxide, calcium phosphate, various salts, vitamins, zinc carbonate, zinc oxide, zinc sulfate.
Fermentation refers to the process by which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare microorganisms themselves, or direct metabolites or secondary metabolites. In general, fermentation means the decomposition of organic matter by organisms. Fermentation is a biochemical reaction for a long history, and it is now widely used in both biological and chemical industries. These products can be obtained from fermentation broth by means of mechanical separation technology. Organic acids, such as lactic acid, citric acid, succinic acid, and other organic materials, can be obtained by SZ decanter centrifuge and disc stack separator. In addition, SZ centrifugal separators can purify the medium of the fermentation process or clarification of the fermentation broth at the preparation stage.
Collection of Algae
Algae can be used as raw materials for foods, biofuels, medicines, cosmetics, etc. SZ decanter centrifuge and disc stack separator can be used for concentrating and separating algal raw materials. Algae can be separated from their medium and processed into high-quality algae concentrates by means of SZ separation equipment. The separation technology used to recycle algae has a decisive effect on the economic benefits of the whole process: it is important to make the investment cost and operating cost of energy, water and so on as low as possible. At the same time, the separated algae concentrate should have the highest possible dry matter content in order to continue its optimal treatment. Algae suspended matter from the bioreactor flows directly into the disc stack separator, and through a high G force up to 12,000G, and then the algae suspended matter can be dehydrated into a cream-like algae concentrate.
