Abstract: Textile industry of fire and dust explosions have occurred, and great harm. The ignition source is one of the conditions lead to accidents. If sparks can be detected before the accident, the accident can be prevented. Spark detection & Extinguishing system can do. Then ,introduced the principle of spark detection & extinguishing system and the basic composition of spark detection & extinguishing system used on pipe, analyzed the spark source produced in textile industry, discussed where the spark detection & extinguishing system is installed. the biggest advantage of the spark detection & extinguishing system is spark extinguished immediately, without affecting the continued operation of the production, and it is a positive way used in the textile industry dust explosion. But for the complete elimination of fire and explosion hazards, for the protection of buildings and equipment other effective measures must be taken.
