Abstract

The invention relates to a fire extinguishing device and method for a floating disk sealing ring, which mainly solves the problem in the prior art that foam liquid enters the sealing ring slowly and cannot quickly extinguish the fire. The present invention adopts a kind of floating disc sealing ring fire extinguishing device, including foam liquid storage tank, foam delivery pipe, dry powder tank, nozzle, foam generator, floating plate, the outlet pipeline of foam liquid storage tank is connected with foam delivery pipe, and foam delivery pipe The other end is connected to the dry powder tank, and the outlet pipeline on the top of the dry powder tank is connected to at least one branch pipeline. Each branch pipeline is equipped with a foam generator and a check valve. The end of the branch pipeline is inserted into the sealing ring, and the end is provided with a T-shaped injection port. The technical scheme that the distance between adjacent spray heads in the sealing ring is not more than 24m solves the above problems well, and can be used for fire fighting in the floating disk sealing ring of the floating roof storage tank and the inner floating roof storage tank.

Description

technical field [0001] The invention relates to a fire extinguishing device and method for a floating disk sealing ring, which is used for fire fighting in the floating disk sealing ring of a floating roof storage tank and an inner floating roof storage tank. Background technique [0002] After a fire breaks out in the sealing ring of the floating plate, foam is sprayed into the sealing ring mainly by means of a fixed foam generator installed on the top of the tank wall, and the foam first flows along the tank wall to the annular space between the tank wall and the foam weir plate. After the foam liquid fills the annular space, the foam overflows the secondary seal of the sealing ring and enters the inside of the sealing ring to cover the oil surface to extinguish the fire. Since the annular space is very large, it takes 5-8 minutes for the foam liquid to fill this space, and the tank wall The height between the foam generator on the top and the sealing ring is relatively la...
