Relying on the National Drying Technology and Equipment Engineering Technology Research Center established by the Tianhua Chemical Machinery and Automation Research and Design Institute, since its formal approval by the Ministry of Science and Technology in November last year, the task of engineering and technology development has been carried out in an all-round way, relying on major national projects. Achievements have been made in the research and development of drying technology and equipment for localization. The coke oven coal moisture control device in the iron and steel industry and the petrochemical industry's one million-ton PTA (pure terephthalic acid) drying technology and equipment have reached the advanced level of the current international similar technology.
After the successful use of the PTA dryer developed by the National Technical Drying Center at the 325,000 tpa/year PTA plant of Sinopec Luoyang Branch, they continued to explore the theory of drying CTA/PTA (coarse terephthalic acid/p-terephthalic acid). Industrial testing, validation and improvement of the CTA/PTA drying mathematical model, mastered the CTA/PTA drying process and equipment design key technologies. In 2007, they took delivery of the 600,000-ton/year PTA CTA/PTA dryer of Jialong Chemical Fiber Corporation.
In February 2008, the center also tagged the Sinopec Yizheng Chemical Fiber 1 million tons/year PTA project CTA/PTA dryer development contract. The 1 million tons/year PTA project of Yizheng Chemical Fiber adopts the process technology of China's independent intellectual property rights. The supporting CTA/PTA dryer is also the largest steam tube rotary dryer independently developed by China. The dryer will be held in March 2009. Delivery installation.
Coking coal moisture control is a technology for improving the quality and reducing consumption. Dry coal processing is performed by heat exchange and the moisture content of the coal entering the furnace is reduced from 10% to 6%, so as to reduce coking oven heat loss and coke quality. The purpose of this technology is to ensure the continuous stability of coke oven production. The steam drying technology developed by the National Drying Center uses the low-pressure steam generated by the dry quenching steam as heat source, and indirect heat exchange with wet coal through a high-efficiency steam pipe rotary dryer to provide a dust recycling system. This technology has been widely used in the coke oven coal moisture control devices of domestic Baoshan Iron & Steel Co., Ltd., Shanxi Huijin Stainless Steel Co., Ltd. and Panzhihua Iron & Steel Co., Ltd. for its remarkable energy saving, environmental protection and economic benefits.
In January 2008, the 330 tons/hour coal moisture conditioning system project of Baoshan Iron and Steel Group was put into on-site installation and construction. The main equipment drying machine is expected to be put into operation in August 2008, and will reduce the fuel consumption of the coke oven by about 2-3 after put into operation. Kg/ton. Shanxi Huijin stainless steel coke oven 400 tons / hour coal moisture control device has entered the equipment assembly phase, is expected to put into operation in March 2008 on-site installation and commissioning. Taiyuan Iron and Steel Company adopts the coal moisture control device built with this technology to put into production, and it is expected to save 30% of coke oven fuel and reduce coking sewage by 30% to 40%. Panzhihua Iron and Steel Co., Ltd. Coking furnace renovation project 350 tons / hour humidity control device is also in the design, the main equipment dryer is expected to be delivered in October 2008 installation.
