From June 12 to 13, the 2012 phosphogypsum comprehensive utilization meeting was held in Guiyang. The meeting released the "12th Five-Year Plan for Implementation of Phosphogypsum Safety Disposal and Comprehensive Utilization" (Draft for Soliciting Opinions). It is proposed that by the end of the "Twelfth Five-Year Plan", the annual comprehensive utilization rate of phosphogypsum will reach 40%; the safe disposal rate of phosphogypsum More than 90%; gradually form a stable comprehensive utilization capacity and long-term mechanism. Li Yongwu, president of the China Petroleum and Chemical Industry Federation, said that the use of phosphogypsum is a difficult problem that the phosphate fertilizer industry must solve. Disposal of phosphogypsum is facing pressures such as land occupation, environmental risks, and hidden safety hazards. The historical leftovers and new quantities that have been generated have affected the sustainable development of the industry. While the state’s requirements for environmental protection have been continuously raised, the National Development and Reform Commission has put forward the goal of comprehensive utilization of phosphogypsum to reach 30% by the end of the “Twelfth Five-Year Planâ€, and the Ministry of Industry and Information Technology requires that it be increased to 40%. Li Yongwu believes that the comprehensive management of phosphogypsum is now focused on solving the "how to do" issue, and hopes that enterprises will raise awareness, scientific research units will speed up technology research and development, industry associations will do a good job in organizing and coordination, and the government will improve its encouragement policies. Li Jing, deputy director of the Department of Liberalization of the National Development and Reform Commission, reviewed the relevant state policies and incentive measures and stated that he will continue to work in macro guidance, system construction, key project support, and atmosphere construction. In particular, Li Jing mentioned that tax reductions and other tax reductions have been made on the comprehensive utilization of resources, and the addition of tax increases to primary resources has become easier to break through. In the future, preferential policies for phosphogypsum will be discussed on the basis of the fairness of various industries. Lei Wen, deputy director of the Department of Energy Resources of the Ministry of Industry and Information Technology, revealed that the Ministry of Industry and Information Technology is compiling the “Advanced Application Technology Catalogue for Comprehensive Utilization of Industrial Solid Wasteâ€, of which the use of phosphogypsum is an important part. In the future, in comprehensive utilization of phosphogypsum, the Ministry of Industry and Information Technology will also strengthen the work on the revision of relevant standards, accelerate the promotion of advanced and applicable technologies and the research and development of key generic technologies, actively promote the pilot work in Guiyang City, and strengthen the research on related fiscal and taxation policies. According to Fu Jing, deputy director of Guizhou Provincial Development and Reform Commission, as one of the pilot bases, the comprehensive utilization rate of phosphogypsum in Guizhou has reached 40% at present, and the new production of phosphogypsum will be completely digested during the “Twelfth Five-Year Plan†period. The participants exchanged views on the issues related to the comprehensive utilization of phosphogypsum. Rongfu Group and Beijing Zhongkuang Longtai Engineering Technology Co., Ltd. introduced the transformation of phosphogypsum storage yard and related technologies for safe and environmentally friendly storage; Kaifeng Group introduced the application of phosphogypsum in the building materials field and related experience; Shandong Lubei The enterprise group, Sichuan University, etc. gave a keynote speech on chemical decomposition of phosphogypsum.
Intelligent leakage detection,
Characteristic
MLD Series of Mechanical Leak Detector MLD Series of Mechanical Leak Detector, Mechanical Line Leak Detection, Mechanical Leak Detector Shanghai Jiasong Machine Co., Ltd , http://www.fuel-dispenser-parts.com
Specifications
Close the valve according to leak flowrate,
timely detection less than 3 seconds.
For Gasoline, Kerosene, Diesel;
The leak detector will control the output of oil in time, when the oil leakage in the pipeline is no less than 11.4L/min;
The leak detector will delay to open in 2-3 seconds, when the oil leakage is less than 11.4L/min;
MLD2 Mechanical Leak Detector can keep maximum flow rate while several nozzles are working at the same time.
With
the growing consciousness of human environmental protection, relevant
environmental protection rules and regulations are made one by one
around the world. In order to observe the local environmental protection
rules and regulations, and to avoid pollution from oil leakage, the
leak detector is developed and put into use widely.
Under
the transmission pressure at 1.4-3.5KPa, diaphragm type of MLD
mechanical leak detector is a selectable device for submersible pump to
monitor the oil leakage in the pipeline. The leak detector can
automatically carry out the supervision to the flow rate over 11.4L/min
or pressure less than 0.6KPa of the pipeline. If leakage existing, it
will limit the flow rate at 11.4L/min through closing the inner piston
valve, which will let the users know that there is oil leakage in the
pipeline.
