碎煤机真空度对环境污染的影响

Discussion of Vacuum of Coal Crusher for Environmental Pollution

论述了燃煤电厂碎煤机真空度直接涉及到煤粉外溢量对环境污染的影响，分析了真空度的大小与污染环境的关系，队及改造碎煤机结构上原设计的不合理之处，有效地将碎煤机的真空控制在零或微负压，控制煤粉的外溢，为减少环境污染及保证工人的身心健康提出了切实可行的建议。

This article discusses that the vacuum of coal crusher directly causes the environmental pollution in the power Station fuelled by coal due to the output quantity of coal powder.The relation between the vacuum and the environmental pollution was analysed. The unreasonable construction of coal crusher was improved. The vacuum was effecticvely controlled in zero or minute negative pressure and the leakage of coal dust was controlled also.The feasible opinion was suggested on mitigating environmental poll ution and safeguarding staffs health.
