  煤泥烘干机系统在工作时会产生一定量的煤尘和可燃气体,操作不当可能形成煤尘爆炸事故,下面真空烘干机厂家给大家分享一下三招预防煤泥烘干机粉尘爆炸:
  Slurry dryer system will produce a certain amount of coal dust and combustible gas when it is working. Improper operation may lead to coal dust explosion accident. The following vacuum dryer manufacturers share three measures to prevent dust explosion of slime dryer:
  1、煤泥烘干机系统中氧气含量的控制
  1. Control of oxygen content in slime dryer system
  实验结果标明,煤泥烘干机系统中的氧含量与温度直接相关。当枯燥机入口温度大于5 0 0℃时,煤泥枯燥系统中枯燥介质的含氧量低于煤尘爆炸的下限浓度。在枯燥机的实践消费过程中,由于进料量小,入口温度为523.5℃,枯燥系统的含氧量小于16%,保证了系统的平安运转。
  The experimental results show that the oxygen content in the slime dryer system is directly related to the temperature. When the inlet temperature of the dryer is higher than 500 C, the oxygen content of the dry medium in the slurry drying system is lower than the lower limit concentration of coal dust explosion. In the process of practical consumption of the dryer, the inlet temperature is 523.5 C, and the oxygen content of the drying system is less than 16%, which ensures the safe operation of the system.
  2、控制煤泥烘干机系统中的粉尘浓度。
  2. Control the dust concentration in the slime dryer system.
  粉尘浓度控制办法是控制系统中气体的速度,以小化煤泥枯燥系统中煤尘的飞散。在枯燥器中,气流的设计速度为5m / s,灰尘不会飞行。同时,粘液位于枯燥器的前端,并且由于高水分含量,根本上没有烟雾产生。仅在煤泥枯燥器的后端,随着煤中的水分不时减少,将产生灰尘。在此阶段,枯燥机的内部构造设置为pur条形的提升板,或者以至设置提升板使得枯燥的资料不再升高以防止灰尘飞扬。另外,控制枯燥产品的水分含量以避免产品过度枯燥,并且还能够减少粉尘产生。

  The dust concentration control method is to control the gas velocity in the control system to minimize the coal dust dispersion in the slime drying system. In the dryer, the design speed of the airflow is 5 m/s, and the dust can not fly. At the same time, the mucus is located in the front of the dryer, and because of the high moisture content, there is no smoke at all. Only at the back end of the slurry dryer will dust occur as the moisture in the coal decreases from time to time. At this stage, the internal structure of the dryer is set as pur strip lifting plate, or even lifting plate is set so that the dry material is no longer raised to prevent dust from flying. In addition, controlling the moisture content of dry products can avoid excessive dryness and reduce dust production.
  3、消弭一切火源
  3. Eliminate all sources of fire
  设置熄灭炉阻挠火墙,避免火花进入煤泥烘干机;控制枯燥后煤泥的温度,防止到达自燃温度;定期清算堆积物,避免煤尘堆积等。
  Set up extinguishing furnace to block the fire wall and avoid sparks entering the slime dryer; control the temperature of the dried slime to prevent it from reaching the spontaneous combustion temperature; check accumulations regularly to avoid the accumulation of coal dust, etc.
  以上三个方面的预防措施能够有效地防止煤泥烘干机系统发作煤尘爆炸的可能性。同时,煤泥枯燥机用户也需求定期对操作人员停止平安学问培训和平安认识教育。只要避免不熄灭和微消弭,设备才干平安、稳定地运转。更多内容点击官网进行咨询:秒速时时彩http://www.jianmosc.com
  The above three preventive measures can effectively prevent the possibility of coal dust explosion in the slime dryer system. At the same time, users of slime dryer also need to stop safety knowledge training and safety awareness education for operators on a regular basis. Only by avoiding non-extinguishing and micro-extinguishing, can the equipment operate safely and steadily. Click on the official website for more information: http://www.jianmosc.com
