Dehumidification and rust-prevention device for marine diesel engine

Abstract

A dehumidification and rust-prevention device for a marine diesel engine comprises a case, a treated air inlet, an electric appliance control cabinet, a temperature and humidity display control instrument, a humidity and temperature sensor box, a regenerated air inlet, a dry air outlet, a humid air outlet, a drying rotating wheel, a rotating wheel driving component, a fan motor, a regenerated air heater, a treatment fan and a regeneration fan. The drying rotating wheel is divided into a treated air region and a regenerated air region and rotates to achieve function replacement and continuous work of the two air regions. Treated air is dried by the drying rotating wheel in the treated air region. Regenerated air is heated and then dehydrates and regenerates the drying rotating wheel in the regenerated air region. The temperature and humidity display control instrument controls the dehumidification and rust-prevention device to be in the working status of intermittent ventilation or dehumidification and rust-prevention according to preset interruption starting time and a comparison result of temperature and humidity signals collected by a temperate and humidity sensor probe and preset temperature and humidity threshold values. The dehumidification and rust-prevention device solves the problem that the interior of the diesel engine rusts when the diesel engine is not in operation and has the advantages of being simple in structure, high in reliability, high in applicability and the like.

Description

technical field [0001] The invention relates to an accessory of a marine diesel engine, in particular to a dehumidification and antirust device for a marine diesel engine, and belongs to the field of electromechanical technology. Background technique [0002] The manufacturing cycle of marine diesel engines is long. After the main engine is assembled, it needs to be packed and shipped. It takes a long time from the shipyard to the dock and station. Therefore, the sealing and rust prevention of the main engine during transportation is very important. [0003] The sealing and rust prevention during the transportation of the main engine generally adopts the measure of installing a dehumidifier on the main engine. During the actual use of the existing dehumidifier, if the fan of the dehumidifier is shut down for a long time, due to the slender and curved ventilation pipeline, marine The air in the cavity of the diesel engine cannot be circulated, so the humidity detected by the ...

[0003] The sealing and rust prevention during the transportation of the main engine generally adopts the measure of installing a dehumidifier on the main engine. During the actual use of the existing dehumidifier, if the fan of the dehumidifier is shut down for a long time, due to the slender and curved ventilation pipeline, marine The air in the cavity of the diesel engine cannot be circulated, so the humidity detected by the humidity probe has a large deviation from the humidity in the cavity of the main engine, so that the dehumidifier cannot be started in time, and the purpose of humidity control cannot be achieved
