The technical principle of the pressure electric osmotic drying machine
The basic principle of electroosmosis dehydration is: under the action of the DC electric field, various water molecules in the sludge will move to the cathode, and the solid is left in the upper layer to realize the separation of solid and liquid. In this process, the combined water and interstitial water in the sludge will become free water, and the sludge will break down and reduce the specific resistance. Theoretically speaking, electroosmosis is suitable for dewatering various kinds of sludge.
Because the electric osmosis has a conditioning effect on the sludge, the pressure dehydration has the precondition. It has been proved by the experiment that the effect of reducing energy consumption by pressure combined with electric osmosis has the effect of increasing efficiency. The device is pressurized in the middle of electroosmosis, and there is an elastic sealing frame with up and down floating around the pressure zone to prevent the sludge from extruding after being pressed. The positive pressure pressure process can be divided into three sections, such as low pressure, medium pressure and high pressure. The elastic sealing frame also plays the role of instantaneous high pressure at the same time, thus realizing the flexible pressurization of the sludge.
Vacuum suction suction through vacuum system can slow down the fouling of the cathode and filter, keep the drainage channel unblocked, speed up the moving speed of water molecules to the cathode, and improve the dehydration efficiency and the capacity of the equipment.
A summary of the application of equipment
The depth dehydration of all kinds of sludge with water content of about 80% can be reduced without the medicament. It can replace the drying machine to burn the sludge after drying, or the sludge drying system in the sludge carbonization process, so that the carbonization process is more optimized and energy saving and the manufacturing cost is reduced.
The sludge dehydration power needs only electricity, and the consumption of cleaning water is small.
It can continuously dehydrate sludge with water content 98-95% to 60-45%.
It has unique advantages for deep dewatering and reduction of hazardous waste such as chemical industry.
In the field of herbal tea residue, Chinese medicine residue and slurry residue, the moisture content of core of straw fiber can be removed to a maximum extent, and the fuel coal burning can save energy consumption.
Pailidi Environmental Engineering Co., Ltd. was founded in March 2008, is the research and transformation base of the Institute of Environmental Science, Fudan University, and with the Institute of High Energy Physics of the Chinese Academy of Sciences, Tsinghua University, Zhejiang University of Technology, Shandong University, Harbin University of Technology and other domestic scientific research institutions, specializing in industrial organic waste gas treatment of environmental protection new technology research, supporting equipment processing and atmosphere, sewage and other environmental engineering general contracting comprehensive high-tech enterprises.
At the same time, Palidis set up environmental protection academician workstation, Shandong plasma waste gas treatment research and development center, environmental protection enterprise of environmental engineering R & D center, there are a large number of innovative, practical technology born here. The company has registered capital of 50 million yuan, has environmental engineering design class B qualification (waste water, waste gas), environmental protection facilities operation and construction project contracting qualification and many other qualifications and perfect certification system.
As a technical enterprise in the industry of industrial odor gas management, perindi has always devoted a great deal of human, material and huge amount of capital to the atmosphere governance, sewage treatment and other environmental technologies with a high sense of social responsibility. At the beginning of the establishment of the company, the DDBD dual medium resistance of the DDBD was introduced for more than 10 years. When introduced, the technology was introduced in the completion stage of the laboratory principle prototype. After 8 years of engineering experiments and research of more than 400 different exhaust sources, the industrial application of DDBD has been realized. A lot of experience has been accumulated and a "low temperature plasma technology" has been created in the world. Palidis is known as the "low temperature plasma technology" industrial waste gas management brand. The technology is energy-saving, environmental protection, and has a wide range of applications. It has been rated as the national Torch Program, national environmental protection demonstration project, the first batch of key recommendation technologies of environmental protection in Shandong Province, and the national environmental protection technology project of National Encouragement and Development. The industrial application of the advanced technology and equipment is the first batch. The industrial application of this technology provides an effective way and technical basis for the odor purification, subverts the traditional technology. At the same time, combined with other waste gas treatment technology, more than 20 new technologies are developed, 60 items are applied for special profit, and the waste gas treatment project is completed by the end of 2015, and 40 works to complete the waste gas treatment project. The 408 item, production standard industrial waste gas treatment equipment 16 series, 150 varieties. In recent years, the company has developed a three-phase multi-medium catalytic oxidation technology, high performance liquid phase TRS purification system, mixed solvent dry cloud recovery and reuse technology, efficient water film separator, ultra clean emission and energy saving practical technology, greatly improved the company's market competitiveness. It has become a modern high-tech enterprise with R & D and design, project consultation, production and sales, and engineering general contracting.
In addition, the Palidis team has more than 10 years of experience in industrial sewage treatment. In the pharmaceutical, coking, printing, dyeing, landfill leachate treatment and other industries, the industrial wastewater treatment and municipal sewage treatment industry, has done a large number of high-quality projects. Has been the environmental protection management department and the user's consistent praise.
