Ventilation system of ro-ro passenger ship cargo hold

Abstract

The invention relates to a ventilation system of a ro-ro passenger ship cargo hold, which comprises a horizontal ventilation system, and is characterized by further comprising a lamination prevention ventilation system, wherein the lamination prevention ventilation system comprises a plurality of lamination prevention ventilation assemblies arranged in a length direction of the cargo hold sequentially; the lamination prevention ventilation assemblies comprise fans (1); air outlets of the fans (1) are communicated with air boxes (3); each air box (3) is communicated with four main spiral ducts (9) which extend upwards to the inferior of a top deck of the cargo hold, extend horizontally to the periphery, and then are communicated with a plurality of branch spiral ducts (10); the tail ends of the branch spiral ducts (10) horizontally face towards a bow or a stern, and then are connected with nozzles (5); the nozzles (5) are inclined downwards, and face towards the same direction; and the branch spiral ducts (10) are fixed below the top deck on the cargo hold.

Description

technical field [0001] The invention relates to a ventilation system, in particular to a ventilation system for cargo holds of a ro-ro passenger ship, and belongs to the technical field of ventilation systems. Background technique [0002] Usually, the cargo hold of ro-passenger ships is a single large cargo hold, which has the characteristics of large capacity and long cargo hold. Its ventilation design must meet the requirements of the International Convention for the Safety of Life at Sea (SOLAS) and relevant national classification societies. Two methods are routinely used: one is natural air intake and mechanical exhaust; the other is mechanical air intake and mechanical exhaust. Corresponding to this, there are many forms of ventilation arrangement, generally horizontal ventilation, the common ones are air intake at the bow and exhaust at the stern; or exhaust at the bow and air intake at the stern. After adopting the above-mentioned ventilation measures, the dangero...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the ventilation system of the existing ro-passenger ship cargo hold is often arranged in a dotted manner at the bow or stern, affected by the layout of the cargo hold, obstacles, etc., the ventilation effect is often not good, and there is often airflow Layered, vented corners and airbags
