METHOD FOR FIRE AND EXPLOSION SAFE STORAGE OF WASTE ON LANDFILL AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2018 - IPC A62C3/02 B09B1/00 

FIELD: fire safety.

SUBSTANCE: invention relates to the field of fire safety at specialized landfills for municipal solid waste and environmental protection, and in particular to a method of fire and explosion safe long-term storage of waste at landfills for solid household and industrial waste. Said method of fire and explosion safe storage of waste at the landfill includes the creation of a space around waste mass limited from the external environment using a sealed domed shell, and the stage of configuration of this space, removal of combustible gases and their liquid condensate from the upper part of the confined space, and extinguishing the fire source with available fire extinguishing agents. At the stage of configuring the space that is limited from the external environment, when a sealed dome-shaped casing, which has limitations in its safe overall dimensions, does not completely cover the entire area of waste, this area is divided into zones. In the future, the area of all zones is covered with an appropriate shell, combustible gases and their liquid condensate are removed, they result from the ongoing biochemical processes occurring in waste mass when it adapts to the specific climatic and landscape conditions of the landfill, a fire on the surface of waste mass in the space limited from the external environment is extinguished by creating an environment in the protected space that does not support combustion by means of aerosol fire extinguishing agents. After the elimination of the source of ignition, additional surface treatment of waste mass is performed with chalked sewage resulting from its repeated recycling through the mass of waste. In the case of the formation of a critical pressure of combustible gases and their liquid condensate in the space limited from the external environment, an abnormal development of events will produce an emergency removal of combustion products into the atmosphere. This claimed method is carried out using a device for fire and explosion safe storage of garbage at the landfill, which contains a sealed dome, forming a limited volume over waste mass, devices for removal of combustible gases and their liquid condensate from the upper part of a limited volume and fire extinguishing means, moreover, the dome perimeter is configured to overlap each zone created on the entire area of waste mass, and on the inner side of each dome, the aerosol fire extinguishing equipment and devices for additional surface treatment of waste mass with previously produced waste water are installed evenly around the perimeter of the device.

EFFECT: claimed technical solution is easy to use and allows fire and explosion safe long-term storage of waste at landfills for solid household and industrial waste, taking into account modern environmental requirements.
