Abstract
This paper describes the origins of the coal chemical industry and its development in the ups and downs, through the analysis of the current world a energy consumption structure, global fossil energy supply, China's prospects fossil energy distribution. The coal chemical industry in China illustrate the range, so that the world scope of necessity of the development and the energy field of chemical industry, the important role of possession. Summarizes the current situation of the development of the coal chemical industry at home and abroad and the future development; Summarizes the purpose of cooling gas preliminary significance; Introduced the drum wind cooling section in the process, now commonly used plant early technology and process flow of the cold commonly used equipment, and kinds of the technology and equipment are analyzed advantages and disadvantages, according to his own design as the subject and the expected goal mainly on the drum the material balance in the cold section is and heat balance calculations of main equipment needed, the type selection and preliminary sure. The economic value is determined primarily this section, and loss situation, the preliminary formulated the main the process design conditions, painted preliminary condensing cooler equipment with the control points diagram, process flow diagram and reservation has been preliminarily determined according to the direction of the wind cooling section of the equipment drum wind floor plan.
