Abstract
The invention discloses a marine inert gases system, comprising a first boiler and a second boiler; wherein flues of the first boiler and the second boiler are communicated with a center guiding pipeof a washing tower. An exhaust gas outlet of the washing tower is connected with a first draught fan and a second draught fan by pipelines, wherein the first draught fan and the second draught fan arein a parallel connection. Discharge pipelines of the first draught fan and the second draught fan are connected with a center windpipe of a deck water seal. A vent port of the deck water seal is connected with an inert gases outlet. A pressure vacuum release device is connected with a pipeline which is arranged between the vent port of the deck water seal and the inert gases outlet. The inventionhas reasonable structure and excellent working performance.
Description
Technical field:
The present invention 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:
The object of the present invention is to provide a kind of rational in infrastructure, the marine inert gases system of favorable working performance.
Technical solution of the present invention 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.
