铁路烤砂间在砂的烘烤运输及贮存过程中散发大量砂尘，污染车间及室外大气环境，已成为路内劳保及环保的重点治理问题。为确定最佳治理方案，铁道部劳卫所汇同西安铁路分局对成都、宝鸡、重庆、北京等地的机务段进行了考察。对两种可行的治理方案的原理及工艺流程进行了介绍，并作了技术经济比较。在此基础上提出了不同地区铁路烤砂间治理的优选方案。
During the roasting, transportation and storage of sand in railways, large amounts of sand and dust, pollution of the workshop and the outdoor air environment have become the key management problems in labor insurance and environmental protection in the road. To determine the best management plan, the Ministry of Railways, Labor and Welfare Exchange with the Xi’an Railway Branch of Chengdu, Baoji, Chongqing, Beijing and other parts of the locomotive were inspected. The principle and technological process of two feasible governance schemes are introduced, and a technical and economic comparison is made. On the basis of this, the paper presents the optimal plan for the management of railway sand roasting in different regions.
