摘要(Abstract):
阐述了选煤厂常用的离心式、螺杆式空气压缩机的工作原理、优缺点及适用范围。结合涡北选煤厂空气压缩机的选择,从主厂房10台120 m2加压过滤机的用风量、压力要求入手,布置多种不同排气量、不同类型的空气压缩机选型方案,对各方案中空气压缩机所需台数、设备购置费用、功耗、后期维护费用等方面进行比较,最终选择投资最省、功耗最低、维护费用少的4台360 m3/min离心式空压机。
Introduce the working principle,merit and demerit,application scope of centrifugal,screw air compressor which are commonly used in coal preparation plant. Taking the air compressor of Guobei coal preparation plant as example,based on the air volume and pressure required of 10 units 120 m2pressure filter at the main plant,layout different engine volume and types of air compressor equipment selection scheme,compare required numbers,equipment acquisition cost,power consumption,maintenance costs of the air compressor for each scheme. Adopt four 360 m3/ min centrifugal compressors for its low investment,power consumption,maintenance cost.
