Abstract
The present invention discloses a device for pulverization and explosion suppression of low carbon gas hydrate (LCGH). A feeding chamber connects with a pulverizing chamber, and the chambers communicate through a feed port. A pulverizing air pipe and the feeding chamber communicate through a feeding air pipe; two ends of a venturi connect with an entrainment chamber and a disperser respectively; and a gas-solid separation membrane (GSSM) is disposed on a discharging port and used for preventing LCGH powder from entering the entrainment chamber from the pulverizing chamber. When an explosion is triggered, the GSSM is opened to make the LCGH powder enter the entrainment chamber. The device can store and pulverize the LCGH and spray LCGH powder to achieve combustion and explosion suppression.
