Claims

[Scope of utility model registration request]

A coke extinguishing system in which a cooling tower, a heat exchanger, a dust collector, a circulation fan, etc. are connected by a circulation duct to form a closed circuit, and a surplus gas duct is branched from between the cooling tower and circulation fan of the circulation duct. In a coke dry extinguishing system in which a plurality of coke extinguishing units are installed in parallel, the surplus gas duct of the first coke extinguishing unit is connected to the inlet side of the heat exchanger of the second coke extinguishing unit, and the Sequentially connect the surplus gas ducts so that they communicate with the inlet side of the heat exchanger of the third coke extinguishing unit,
The surplus gas duct of the last coke extinguishing unit in parallel is connected to the inlet side of the heat exchanger of the first coke extinguishing unit via a common duct, and is further connected between the gate valve and the flow control valve provided on each surplus gas duct. A coke dry fire extinguishing system characterized in that each surplus gas duct and the common duct are connected by a communicating duct.
