Mechanical defoamer

Mechanical defoaming widely used in industrial production to eliminate the foam, especially for pulp and paper foaming night environment. Pulp and paper black liquor produced during the saponification product contains a lot of disturbance or easily generate foam on contact with air, producing serious pollution of the environment, resulting in the loss of valuable resources, clean production enterprises to achieve a major technical problem. The defoamer component: includes motor, spindle, the impeller, the exhaust port, characterized by: further having a guide tube and guide the outer cylinder and the inner cylinder between said flow diversion constitutes an outer cylinder said impeller is coaxial two-layer structure, the first layer is located inside the guide tube, the second layer is located outside the guide tube; trapping chamber. A layer between said orifice double impeller. There is a diversion of the expansion chamber outer cylinder. A discharge port, and a foam return conduit connected to the collection tank on said outer guide tube. Use of induced separation theory, devised a formula to induce anti-foaming structure, with a unique double-impeller. How it works: diversion diversion along the inner tube guided foam inner tube near the high-speed rotation of the impeller to rise, the first layer of foam Shuaixiang first impeller diversion inner tube, the tube wall and the foam strike was broken into a liquid, the liquid along the tube wall flow back into the collection tank; in the process air can escape while wrapped up with a portion of the foam escapes through the orifice into the impeller outer guide tube, the second layer further Shuaixiang impeller outer guide tube, the outer wall of the collision into a liquid, which is the second trap, this part of the liquid through the trap chamber and the return pipe back into the collection tank; air escaping from the top of the impeller into the diffusion chamber, the diffusion chamber may be wrapped with a small amount of further trapping small droplets, so after three trap, only clean air is discharged through the top of the exhaust pipe. This back and forth cycle, the foam can be one hundred percent without the need to add any defoamers eliminate. The present invention induce separation foaming, high collection efficiency can be 100 percent anti-foaming, no defoamers, without any environmental pollution problems, but also with a compact, reliable, easy operation and maintenance advantages. All industries can be used to produce foam. Silverwing machinery equipment production and sales of anti-foaming, powder flow of heat transfer equipment, paper machinery, environmental protection equipment, transportation equipment. www.yinyijixie.com
