Cabin ventilation device with air draft function and implementation method thereof

Abstract

The invention discloses a cabin ventilation device with an air draft function, which belongs to the technical field of ventilation devices. The cabin ventilation device comprises a ventilation and airexchange box, the upper end of the ventilation and air exchange box is connected with a ventilation pipe and a ventilation pipe, and the ventilation pipe and the ventilation pipe are both connected with a connecting cover; the other end of the connecting cover is connected with a ventilation pipeline, and the lower end of the ventilation pipeline is connected with a ventilation base. Ventilationand air exchange are carried out through air exhaust of the ventilation and air exchange box, air circulation is carried out through independent work of an aspirator and an exhaust fan and through independent pipelines, mutual interference is avoided, and ventilation and air exchange are convenient; a ventilation cavity and an air exchange cavity are formed in the ventilation pipeline, ventilationis conducted through one pipeline, fixed installation is convenient, and the situation that the size is too large due to the fact that multiple pipelines are connected is avoided; an exhaust cylinderand an air inlet cylinder are arranged, an overturning adsorption net is arranged in the air inlet cylinder for moisture adsorption, fan blades are arranged in the exhaust cylinder, the exhaust portis formed in the side edge, and the poor ventilation effect caused by mixing of ventilation and air exchange gas is avoided.

Description

technical field [0001] The invention belongs to the technical field of ventilation devices, and in particular relates to a cabin ventilation device with an exhaust function and an implementation method thereof. Background technique [0002] The cabin refers to various spaces below the deck, including the bow cabin, stern cabin, cargo hold, machine room and boiler room. The interior space below the deck of a ship; especially the cargo compartment of a ship, mainly referring to the activity space. [0003] The prior art has the following problems: the existing cabin ventilation device cannot be ventilated during use, and ventilation is inconvenient, resulting in defects in daily use; and multi-pipe connections result in large volume, inconvenient fixed installation, and inconvenient ventilation gas filtration ; Simultaneous ventilation and ventilation mixed gas resulting in poor ventilation. Contents of the invention [0004] In order to solve the problems raised in the ab...
