Sealed space air purification device based on marine navigation ship

Abstract

The invention relates to the technical field of air purification devices, and discloses a sealed space air purification device based on a marine navigation ship. The sealed space air purification device comprises a ventilation pipe, a fan shell and a control box, the ventilation pipe is fixedly mounted on the outer wall of a sealed space, the fan shell is fixedly mounted on the front side wall surface of the ventilation pipe, and the control box is fixedly mounted below the side wall of the fan shell; a fan is fixedly installed in the fan shell, and filter screens are fixedly installed on the side, away from the fan shell, of the interior of the ventilation pipe and the front side and the rear side of the interior of the fan shell. According to the device, the space in the ventilation pipe is the maximum passable area, the larger the angle between the sealing plate and the cross section of the ventilation pipe is, the larger the passable area in the ventilation pipe is, an adjusting bolt is installed on an adjusting plate through threads, and the adjusting bolt can make contact with the ventilation pipe through rotation; therefore, the adjusting plate and the sealing plate can be fixed, and the effect that the ventilation speed can be adjusted at will is achieved.

Description

technical field [0001] The invention relates to the technical field of air purification devices, in particular to an air purification device for confined spaces based on seagoing ships. Background technique [0002] In the shipbuilding and chemical industries, production personnel often work in confined spaces. Due to poor ventilation in confined spaces, toxic and harmful gases are not easy to emit, which will cause safety accidents of production personnel poisoning, and production personnel are prone to heatstroke in high temperature weather, so it is necessary Install ventilation in confined spaces. [0003] And the size of the internal air duct of existing ventilation device on the market is generally all fixed, thereby can't regulate the speed of ventilation. To this end, we propose an air purification device for confined spaces based on seagoing ships. Contents of the invention [0004] The present invention mainly solves the technical problems existing in the above...

Problems solved by technology

[0002] In the shipbuilding and chemical industries, production personnel often work in confined spaces. Due to poor ventilation in confined spaces, toxic and harmful gases are not easy to emit, which will cause safety accidents of production personnel poisoning, and production personnel are prone to heatstroke in high temperature weather, so it is necessary Install ventilation in confined spaces

[0003] However, the size of the internal air ducts of existing ventilation devices on the market is generally fixed, so that the ventilation speed cannot be adjusted.
