MOBILE DEGASSING COMPLEX Russian patent published in 2020 - IPC E21F7/00 

FIELD: mining.

SUBSTANCE: invention relates to mining industry, to ground mobile degassing units and is intended for pumping gas-air mixture, including methane-air mixture, from coal mines and mines. Mobile degassing complex includes cyclones and fine filters equipped with gates, and an intermediate gas line between cyclones and fine filters is looped. Provided is possibility of replacing fine filters without complex shutdown; possibility to maintain required number of simultaneously operating cyclones depending on gas-air mixture flow rate; possibility of blowing the whole complex; possibility to clean accumulator from water and solid residue without complex shutdown. Fine filters and flame arresters are equipped with pollution control sensors, and gates with pneumatic drive are equipped with handwheels. In process rooms there are exhaust fans to create negative pressure, and in rooms of control system there are supply fans to create excess pressure.

EFFECT: technical result is higher efficiency of gas-air mixture cleaning, operating reliability, higher level of explosion safety of premises, manufacturability and safety of mobile degassing complex maintenance.
