压力电渗透干化机技术原理

    电渗透脱水的基本原理是：在直流电场的作用下，污泥中各种水分子会向阴极移动，固体留在上层，从而实现固液分离。在此过程中污泥中的结合水、间隙水会变为游离水，污泥实现破壁，比阻降低。从理论上讲，电渗透可适合各种污泥的脱水。

由于电渗透对污泥有调质作用，使加压脱水具备了前提条件，实验证明，加压结合电渗透对提供脱水效果降低能耗具有增效提产的作用。 本设备加压在电渗透中段施加，压区四周设计有可上下浮动的弹性密封框，防止污泥受压后挤出。正压加压过程分为低压、中压、高压三段，弹性密封框在密封的同时还起到缓冲瞬间高压作用，从而实现对污泥的梯次柔性加压。

   负压抽吸通过真空系统对压滤液进行抽吸，可减缓阴极和滤网结垢，保持排水通道畅通，加快水分子向阴极移动速度，提高脱水功效和设备产能。

设备应用综述

不加药剂可以对含水率80%左右的各种污泥进行深度脱水减量，可替代烘干机对污泥进行干化后焚烧，或用于污泥碳化工艺中污泥干化系统，使碳化工艺更加优化节能，制造成本降低。 

污泥脱水动力仅需电力，清洗水耗量小，适用污泥集中处置项目。

 和叠螺机等设备组合，可将含水率98-95%污泥连续脱水到到60-45%。

 对化工等危废污泥深度脱水减量具有独特的优势。 

在凉茶渣、中药渣，浆渣领域，可最大限度去除秸秆纤维芯部水份，制成燃料掺煤焚烧可节约能源消耗。

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.
