(2) enough large shock wave to be had just can to rush and to turn over water bag or stone-dust barrier;
(3) datonation-inhibition Best Times is the moment that gas has just detonated, and now passive type cannot play a role;
(4) water capacity in water bag is easily evaporated, and runs into dust and easily condenses, therefore need.
Active explosion suppression method mainly comprises: after ultraviolet flame sensor receives burning things which may cause a fire disaster or explosive flame signal, input control device, explosion suppressor is triggered by controller, explosion suppressor is rapid to be in a triggered ejected into extinguishing chemical on flame front to put out burning things which may cause a fire disaster or explosive flame, thus reach the object preventing flame generation, stop detonation propagation, compared with passive explosion-suppressing method, the good stability of the parts adopted in active explosion suppression method, can at blast first arrival first attack, and the method automaticity is high, but there is following shortcoming with not enough in active explosion suppression method:
(1) when active explosion suppression method is implemented, blast occurs, and the method does not comprise early warning and pretreatment measure, and therefore the method can not avoid blast to occur;
(2) sensor adopted in active explosion suppression method is ultraviolet flame sensor, and this sensor only detects flame, and therefore detected parameters is single.
