When the explosion suppressor body 300 is started to generate recoil force, the sliding plate 210 is driven to stably slide between the two guide plates 120.
Depending on the type of installation facility, the installation plate 110 is a flat plate in the case of a planar facility such as a wall, and the installation plate 110 is an arc plate matching the flat plate in the case of a duct facility.
As an optional implementation manner, a plurality of horizontal sliding grooves 121 are respectively formed on opposite surfaces of the two guide plates 120, and a plurality of guide sliders 400 matched with the horizontal sliding grooves 121 are respectively connected to two sides of the sliding plate 210. The sliding plate 210 slides stably on the horizontal sliding groove 121 through the guide slider 400, and then slides stably between the two guide plates 120.
It should be noted that, the guide slider 400 may be a T-shaped slider, and the horizontal sliding groove 121 is a T-shaped sliding groove matched with the T-shaped slider, so as to have an anti-falling function; the slide guide 400 may also be a slide roller assembly, and the horizontal sliding groove 121 adopts a slide guide structure matching with the slide roller assembly.
As an alternative embodiment, a plurality of sets of clamping mechanisms 500 are arranged on the sliding plate 210, and the clamping mechanisms 500 are used for clamping and fixing the explosion suppressor body 300.

As an optional implementation manner, the explosion suppressor body 300 includes an outer housing 310 connected to the sliding plate 210, a pressure storage chamber 320, a filling chamber and a release chamber 330 are sequentially arranged in the outer housing 310, the pressure storage chamber 320 is connected to a pressure pipe 340, the filling chamber is filled with an explosion suppression medium 350, an electric detonator 360 embedded in the explosion suppression medium 350 is further arranged in the filling chamber, and one end of the release chamber 330 away from the filling chamber is provided with a plurality of release holes 331. An auxiliary rupture disk 370 is connected to one end of the electric detonator 360 close to the release cavity 330, and a main rupture disk 380 is arranged between the filling cavity and the release cavity 330.
In this embodiment, the electric detonator 360 is electrically connected to an actuator (not shown) through a conducting wire, the pressure tube 340 is used for connecting a nitrogen pressurization device (not shown), when the detector (not shown) detects a dangerous source, the pressure tube 340 pressurizes the pressure storage cavity 320 to 6MPa or more, a voltage signal generated by the actuator ignites the electric detonator 360 to burst the auxiliary rupture disk 370, the generated pressure induces the main rupture disk 380 to burst, and the explosion suppression medium 350 is ejected from the release hole 331 under the push of high-pressure nitrogen, thereby suppressing the fire source and playing an explosion-proof role. In this process, the time from the arrival of the signal until the explosion suppressor completely covers the protected space is called the overall response time of the explosion suppression system, which is usually 30ms to 100ms, and in industrial equipment, the typical value is 50ms, and the time from the arrival of the signal until the detector sends out the trigger signal is the detection response time, which is usually less than 1 ms.

Among them, the explosion suppression powders such as ammonium dihydrogen phosphate, sodium bicarbonate, potassium bicarbonate, etc. have good explosion suppression effect, and are most commonly used, and the main functions of the explosion suppression powders are to destroy chain reaction (chemical effect), reduce oxygen concentration (chemical effect) and absorb heat to reduce temperature (physical effect).
As water is harmless to human bodies and is cheap, a large amount of documents research the explosion suppression effect of water, the explosion suppression effect of water is not superior to that of chemical explosion suppression powder (ammonium hydrogen phosphate and the like), but the explosion suppression effect is also good, and the explosion suppression effect is as follows:
(1) chain reaction destructive effect
The ultra-fine water mist droplets can be combined with free radicals in the chain reaction to destroy the chain reaction;
(2) wave absorption effect
The shock wave is when in contact with the water droplet. Larger water droplets are broken into smaller water droplets, and the smaller water droplets are vaporized into water vapor to absorb energy, so that the shock wave energy is attenuated;
(3) inerting effect
The oxygen concentration is greatly reduced when the water drops are vaporized into water vapor;
(4) heat absorption effect
When the flame front (reaction area) is contacted with water drops, the vaporization heat absorption of the water drops can reduce the temperature of the reaction area, thereby reducing the propagation speed of flame and even extinguishing the flame;
the chain reaction destructive effect of water can be improved by adding the explosion suppression powder in the water.
However, water is prone to freezing at low temperatures and requires heating systems to prevent freezing in some seasons.
In addition, haloalkane (commonly known as halon) is a very good explosion suppressant, and previous studies showed that CF3Br had a chemical effect of 88% and a physical effect of 12%, while sodium bicarbonate had a physical effect of 47%.
The above description is only a preferred embodiment of the present application, and not intended to limit the scope of the present application, and all the equivalent structures or equivalent processes that can be directly or indirectly applied to other related technical fields by using the contents of the specification and the drawings of the present application are also included in the scope of the present application.
