Research And Implementation Of An Air Compressor Waste Heat Recovery System

Most of plants need to use air compressor to compress air, air compressor in air compression process will produce a lot of heat, resulting in compression of air temperature. In the traditional use of the process, often in order to meet the work requirements need to be equipped with air compressor circulating cooling water or chilled water for compressed air for heat exchange cooling to ensure its stable operation, while producing this part of heat is emitted into the atmosphere. This not only the loss of a large amount of heat energy at the same time also caused the production of cooling water or chilled water consumption volume rises substantially. In order to recover the heat while reducing energy consumption of refrigeration system, with an existing with air compression station of a factory as an example, through the theoretical analysis and practical research this paper introduces a kind of waste heat recovery technology, the original air compressor cooling system based on improved, air compressor in the compression of the export pipeline mounted on the valve, a cooling system and a heat exchange system, and realize the temperature of cooling water and cooling water automatic control, without affecting the normal operation of air compressor under the condition of air compressor compressed air to do work and generates heat instead of for other processes required for raw water heating energy, thereby reducing the used for air compressor cooling and heating energy consumption of production process, at the same time in the original air compressor cooling system based on improved, reducing a portion of the cooling system is used to reduce the energy consumption of the cooling system for the purpose of. Combined with field investigation and assessment on energy saving operation means, calculates the heat utilization energy saving effect, and study the heat recovery efficiency of the general calculation method, at the same time of industrial compressed air system in the present new energy technology characteristics and application range are analyzed and discussed, for the future on the basis of to carry out energy management contract model lays the foundation of technology for energy-saving enterprises, provides the theory basis. It has good economic and social benefits.
