Abstract
The utility model discloses a marine inert gas system which comprises a first boiler and a second boiler. Flues of the first and the second boilers are communicated with a central duct of a washing tower; a flue gas outlet of the washing tower is connected with a first fan and a second fan connected in parallel through a pipeline; air outlet pipes of the first and the second fans are connected with a central air pipe of a deck water seal; an air outlet of the deck water seal is connected with an inert gas outlet through a pipeline; and a pressure vacuum releaser is connected with the pipeline between the air outlet of the deck water seal and the inert gas outlet. The system has the advantages of reasonable structure and good working performance.
Description
Technical field:
The utility model relates to a kind of marine inert gases system.
Background technology:
The major cause that oil tanker is installed inert gas system is exactly that the danger of cargo hold internal combustion and blast is dropped to bottom line.Burning takes place cargo tank and blast must possess three key elements simultaneously:
1. there is enough oxygen to supply with;
2. combustable gas concentration is in " combustion explosion scope ";
3. ignition source is arranged, and its energy reaches the combustible gas required minimum ignition energy that burns.
And the gas that makes cargo tank is in outside the incendivity Explosive Range the simplest way also is the way of easy realization; be exactly in the cabin, to fill very low " unreactable gas " of oxygen content; inert gas system is applied on the tank vessels such as oil tanker; by reducing oxygen content; the danger of the burning of cargo hold and blast is reduced to bottom line, thereby plays protection hull purpose of safety.
All there is defective in existing marine inert gases system at aspects such as structure and safetys.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the marine inert gases system of favorable working performance.
Technical solution of the present utility model is:
A kind of marine inert gases system, it is characterized in that: comprise first, second boiler, the flue of first, second boiler communicates with the centre pipe of scrubbing tower, the exhanst gas outlet of scrubbing tower is connected by pipeline first, second blower fan with parallel connection, the discharge pipe of first, second blower fan is connected with the center tracheae of deck water seal, the air extractor duct of deck water seal is connected with the unreactable gas outlet by pipeline, the plumbing connection between the air extractor duct of pressure vacuum releaser and deck water seal and the unreactable gas outlet.
