Problems solved by technology

[0002] Dust not only endangers the normal operation of equipment and human health, but also has the potential of explosion in dust particles
Existing dust suppressors are generally single-function water mist dust reduction. Due to the limited contact surface of water mist and poor adsorption effect, the existing dust suppressors are not effective in use. In order to achieve the dust reduction effect, the water consumption is increased to cause waste of water resources.
Especially the coal dust produced in the coal mine production process is oily, so it is difficult to absorb oily coal dust with water mist, and the dust reduction effect cannot be achieved

Embodiment approach 1

[0047] The foam 109 produced by the foam dust reduction and explosion-proof device can be sprayed to the dust generation place through the gun head 108 for dust reduction. The good adsorption of the foam 109 will be divided into adsorption and fixation, and at the same time, it will form a dust hard shell after drying to fix the dust.

Embodiment approach 2

[0049] The foam 109 produced by the foam dust suppression and explosion-proof device can wrap the dust-generating place through the gun head 108 for dust reduction. The huge contact surface of the foam 109 layer will wrap the dust-generating place, preventing the dust from spreading and eliminating the dust at the source.

Embodiment approach 3

[0051] The foam 109 produced by the foam dust reduction and explosion-proof device can carry out regional foam 109 filling anti-fire, foam 109 explosion-proof and regional foam 109 isolation, foam 109 has extremely strong fire extinguishing performance, and the foam 109 filled area can effectively prevent the disaster from spreading at the same time, Especially for gas explosion and coal dust explosion foam 109 filled area can effectively reduce or eliminate disasters.

Abstract

The invention discloses a foam dust-fall explosion prevention device which mainly comprises a foam making tube, a foaming agent, a filter screen device, a water feed inlet, a material feed inlet, an air feed inlet, a foam discharge outlet and a spearhead. According to the invention, foams are made in the foam making tube by using the foaming agent, the filter screen device and air flows, and then the manufactured foams are discharged from the foam discharge outlet and the spearhead to carry out dust-fall operation; because the foams are good in adsorbability and ultra-large in contact surface, the dust-fall effect is prominent; dried foams can be condensed into a solid dust protection shell, and in case of explosion hazards or fires, an effect of area foam partition can be formed for carrying out explosion-proof fire fighting; and the problems that the existing dust-fall equipment is single in function and poor in dust-fall effect and coal-dust-like oily dust water-atomized falling dust is difficult to adsorb are solved. The foam dust-fall explosion prevention device has the advantages of simple structure, convenience in daily operation, safety in operation, more auxiliary functions, strong falling dust adsorbability, and large dust-fall contact surface.

Description

technical field [0001] The invention relates to a foam dust suppression explosion-proof device. Background technique [0002] Dust not only endangers the normal operation of equipment and human health, but also has potential explosion hazards in dust particles. Existing dust suppressors are generally single-function water mist dust reduction. Due to the limited contact surface of water mist and poor adsorption effect, the existing dust suppressors are not effective in use. In order to achieve the dust reduction effect, the water consumption is increased to cause waste of water resources. Especially the coal dust produced in the coal mine production process is oily, so it is difficult to absorb the oily coal dust with water mist, and the dust reduction effect cannot be achieved. Develop a foam dust-reducing explosion-proof device suitable for the special environment of mines. This tool should have the advantages of simple structure, convenient daily operation, safe operation...
