Problems solved by technology

Because ship exhaust contains particulate matter, carbon monoxide, nitrogen, oxygen, sulfide, and volatile organic waste gases, among which carbon monoxide and most volatile organic waste gases are flammable and explosive, and oxygen is also a combustion-supporting gas, ship exhaust is difficult to be directly utilized , if ship exhaust gas is directly used for fire fighting and explosion suppression work, it will cause secondary disasters and aggravate the degree of fire damage

Abstract

A ship fire extinguishment and explosion suppression system comprises a particle trap, a desulfurizing and degassing device and a heat exchange device. The particle trap is connected with a ship exhaust gas collecting cover. Exhaust gas is subjected to primary cooling through the ship exhaust gas collecting cover. Particles in the ship exhaust gas are removed through the particle trap. The exhaustgas is deoxidized twice through the desulfurizing and degassing device, and meanwhile, sulfide, carbon monoxide and organic gas in the exhaust gas are removed. The exhaust gas is subjected to secondary cooling through a heat exchanger in the heat exchange device. The exhaust gas finally reaches to a shunt pipe through a buffer tank in the heat exchange device and then reaches fire extinguishmentnozzles to achieve fire extinguishment and explosion suppression. The ship fire extinguishment and explosion suppression system integrates the functions of ship exhaust gas treatment, preparation of agaseous extinguishing agent and seawater cooling and produces the nitrogen and carbon dioxide mixed gaseous extinguishing agent. The problems that the exhaust gas prepared extinguishing agent contains particles, oxygen, carbon monoxide and organic gas and is high in temperature are solved. Fast and high-efficiency totally-flooding inertion cooling on a whole ship is achieved.

Description

technical field [0001] The invention belongs to the field of ship security, in particular to a ship fire extinguishing and explosion suppression system. Background technique [0002] At present, more than 80% of the world's international trade is realized through ocean transportation, and ships are the most common means of sea transportation. According to incomplete statistics, ship fires accounted for 11% of the total number of shipwrecks, ranking fourth. Ship fire has the characteristics of concealed fire point, many and complex combustibles, large fire load, strong thermal conductivity, easy fire and explosion, and very difficult to fight. Therefore, it is particularly important to strengthen the control of ship fires, especially the control of initial fires. The engine room is the heart of a ship and a key place for fire safety. There are combustible substances (such as fuel oil) and cargo sources in the engine room. Electrical fires, fuel fires, explosions and other a...
