Two key projects in Weinan City, Shaanxi Province, have commenced construction. Author/Source: Huahua Network Coal Chemicals. Date: February 24, 2021. Clicks: 137. A total of 527 key projects have been planned for Weinan City in the course of the year, with a total investment of 329.8 billion yuan; the annual investment amount is 106.1 billion yuan. Of these projects, 110 are in the manufacturing sector, with a total investment of 57 billion yuan; 297 new projects were launched, with a total investment of 120 billion yuan. There are 75 projects starting construction this time, with a total investment of 18.9 billion yuan, and the planned annual investment amounts to 8.64 billion yuan. The Shenwei Pipeline Excess Coal Slurry Utilization Project in Pucheng County is part of the Shenwei Pipeline coal transportation project; its total investment amounts to 1.078 billion yuan, with a total construction area of 47,900 square meters. The project includes the construction of a coal slurry dewatering facility with an annual capacity of 1.48 million tons (for raw coal), as well as a concentration facility with an annual capacity of 3.32 million tons (for raw coal). There will also be facilities for storing and transporting the dewatered coal, with an annual capacity of 6.2 million tons, along with a wastewater treatment system capable of handling 3.72 million cubic meters of wastewater per year. Additionally, various supporting utilities will be installed. Once operational, the project is expected to generate an annual output value of 4 billion yuan and create 161 job opportunities. On February 18th, at the R&D and production base for mining polymer materials located in Weinan, under the Shaanxi Coal Technology Research Institute, the Weinan Municipal Party Committee and government held the “Second Weinan City Project Launch Mobilization Meeting and the Inauguration Ceremony for the R&D and production base for polymer materials in Weinan High-Tech Zone”. In a warm and solemn atmosphere, the signal was given to commence construction in the Year of the Ox. In line with its development needs and plans, the Shaanxi Coal Research Institute intends to establish three industrial bases in Weinan: one in Gaoxin, another in Huazhou, and a third in Pucheng. The R&D and production base for mining polymer materials in Weinan’s Gaoxin District, which is set to begin construction now, will require an initial investment of 1 billion yuan. It will feature industry-leading R&D platforms focused on the development of new materials for mining use and intelligent equipment technologies, as well as demonstration projects related to polymer and inorganic materials. Once completed, this facility is expected to generate annual sales revenues of over 2 billion yuan. Going forward, further research and development efforts will be carried out in areas such as intelligent monitoring systems for mining, testing equipment, and intelligent spraying robots, with the goal of turning Weinan’s Gaoxin Base into a model site for industrial development and commercialization driven by advanced mining materials and intelligent equipment manufacturing.
A technology that utilizes ultrasound to desorb activated carbon, which has been used to treat wastewater containing organic substances and heavy metal ions through filtration, once it reaches adsorption saturation; this is a technique for regenerating the activated carbon. As ultrasonic high-frequency sound waves propagate through a medium, they generate intense mechanical vibrations. These waves radiate forward in the cleaning medium in an alternating pattern, causing the liquid to move and creating tens of thousands of tiny bubbles. The small bubbles in the liquid (cavitation nuclei) vibrate violently under the influence of the sound field. When the sound pressure reaches a certain level, the bubbles expand rapidly before suddenly collapsing. When these bubbles collapse, shock waves are generated, creating pressures of several thousand atmospheres in their vicinity; this destroys insoluble contaminants and forces them to break free from the carbon pores, dispersing them throughout the cleaning solution. In this way, the purification of the micro-porous structure of activated carbon as well as its surface is achieved, enabling the desorption and reactivation of the activated carbon. It enables low-energy in-situ dynamic regeneration; the regeneration cost is low, and there is no secondary pollution. The adsorption efficiency of the regenerated activated carbon is superior to that of new carbon, being 95–130% of the latter’s efficiency. The loss rate of activated carbon is less than 0.3% per regeneration, allowing for a long service life and repeated use at low cost. WeChat: 18171595827, Manager Duan.
