China's key casting large drying equipment "China Core"

"National Drying Technology and Equipment Engineering Technology Research Center" is based on Tianhua Chemical Machinery and Automation Research and Design Institute. Since it was formally approved by the Ministry of Science and Technology in November last year, the task of engineering technology development has been fully carried out. Relying on the large-scale drying technology and equipment localization research and development achieved gratifying results: the steel industry coke oven coal moisture control device and the petrochemical industry million tons grade PTA (pure terephthalic acid) drying technology and equipment to achieve the current international advanced technology of the same kind Level.

After the successful use of the PTA dryer developed by the National Drying Technology 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. Yizheng Chemical Fiber's 1 million tons/year PTA project adopts the process technology of China's independent intellectual property rights, and the supporting CTA/PTA dryer is also the largest steam tube rotary dryer independently developed by China. The dryer will be delivered in March 2009. 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 the heat source, and the indirect heat exchange with the wet coal through a high-efficiency steam tube rotary dryer and a dust recovery treatment 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 dryer is expected to be put into operation in August 2008, and will reduce the fuel consumption of the coke oven by about 2 to 3 after put into operation. Kg/ton. Shanxi Huijin stainless steel coke oven 400 tons / hour coal humidity control device has entered the equipment assembly phase, was 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 operation and is expected to save 30% of coke oven fuel and 30% to 40% of coking sewage. Panzhihua Iron and Steel Co., Ltd. coke oven excavation 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.

Cabinet Dryer


The RCD series of cabinet dryers are mostly used for simultaneous drying of different kinds of polymers in small quantities or for drying material for trial mounding. They can also be applied in electronic engineering, electroplating, pharmacy, paint baking,
printing industries and etc.for preheating or drying related products.
Features:
1. Accurate P.I.D. temperature control to achieve an even drying effect.
2. Air tight insulating door can maintain temperature constantly inside to reduce energy consumption.
3. Stainless steel tray and liner bring no contamination to materials.
4. Optimal design for easy maintenance and service.
5. Unique-designed adjustable air inlet and exhaust.
6. Overheat protector can prevent excessive drying.
7. Motor overload relay.
8. 24-hour timer, easy to operate.
9. Visible alarm to indicate emergency trouble.
10. Tray size and inner dimensions of the dryer can be specified according to requirements.


Introduction
For RCD series cabinet dryers, materials to be dried are placed on the stainless steel made moveable material trays. During operation, process air will flow to heating wire and be heated up to required temperature, then flow through a manifold with evenly scattered holes. Moisture air is sent out through air exhaust port. It is designed to achieve an even drying effect.
