A low-carbon gas hydrate crushing explosion suppression device

Abstract

The invention discloses a low-carbon gas hydrate crushing explosion suppression device, which includes a crushing chamber, a feeding chamber, a crushing air pipe, a venturi tube, a nozzle and a gas-solid separation membrane. There is a feeding port, the feeding port is provided with a sealing cover, the crushing chamber is connected with the feeding chamber through the feeding port, and the feeding port is provided with a switch valve; the crushing air pipe is connected with the feeding chamber through the feeding air pipe, and the crushing air pipe and the feeding air pipe are respectively set There are a first valve and a second valve; the two ends of the venturi tube are respectively connected to the entrainment chamber and the disperser; the nozzle extends into the entrainment chamber; the gas-solid separation membrane is set at the discharge port to block the low-carbon gas hydrate powder The powder enters the entrainment chamber from the crushing chamber, and when the explosion is triggered, the gas-solid separation membrane opens to allow the low-carbon gas hydrate powder to enter the entrainment chamber. The low-carbon gas hydrate crushing explosion suppression device can store and crush low-carbon gas hydrate and spray low-carbon gas hydrate powder to realize the function of suppressing combustion and explosion.

Patent document CN208399416U discloses an experimental device for suppressing explosions by using low-carbon mixed gas hydrates, which can be used for experimental research on gas explosion suppression by using low-carbon mixed gas hydrates, and provides basic device design for experimental research on hydrate suppressors, effectively solving Solving the problem of limited explosion suppression effect, it has guiding significance for the suppression of gas explosions in coal mines and the storage and transportation of flammable gases, and the low-carbon gas hydrate powder containing explosion suppression ingredients is green and environmentally friendly, but the application of low-carbon gas hydrates to suppression The main bottleneck of fire and explosion lies in the preparation, storage and spraying of hydrate powder

If the low-carbon gas hydrate is crushed first to make powder, and then taken out and placed in the injector, the hydrate powder is easy to decompose during this process and the surface is easy to form an ice surface to cause the hydrate to agglomerate, which makes it difficult to ensure that the fire and explosion The powder can be sprayed out in time

In order to avoid problems such as powder decomposition and powder injection channel blockage during the explosion suppression process of hydrate powder, there is an urgent need for an explosion suppression device that can efficiently prepare, store and spray gas hydrate powder
