Polar ship lifeboat cabin preheating system and method

Abstract

The invention provides a polar ship lifeboat cabin preheating system. The system includes an exhaust pipe provided with a first valve and communicating with a high-temperature exhaust gas discharge port of a marine main engine, a first heating line and a second heating line, the first heating line is provided with a second valve and a sixth valve, the second heating line is provided with a third valve and a fourth valve, the outlet end of the exhaust pipe is provided with a fifth valve, the second valve and the third valve are communicated with the inlet end of the exhaust pipe through a pipeprovided with a seventh valve, the fourth valve and the sixth valve are communicated with the outlet end of the fifth valve through a pipe, and the heat storage materials fill around the first heatingpipe and the second heating pipe. The polar ship lifeboat cabin pre-heating system utilizes the high-temperature exhaust gas of the main engine of the ship to heat the lifeboat cabin. In case of emergency, the lifeboat can be quickly activated. The heat storage material can also ensure that the lifeboat has a certain heat source after leaving the polar ship, and maintain the cabin environment ofthe lifeboat.

Description

technical field [0001] The invention relates to a preheating system and method for a lifeboat compartment of a polar ship, belonging to the technical field of polar equipment environment control. Background technique [0002] With the development of modern large-scale ocean-going ship construction technology and human exploration of the earth's polar resources and climate, the design of polar ships has become the focus of the world's attention. With the gradual development of polar oil and gas resources, the demand for polar ships has gradually increased, and the demand for ship equipment that meets the requirements of polar regulations and environmental conditions has also increased accordingly. Affected by the polar low temperature environment, the liquid on the polar lifeboat will freeze into ice; the closed or semi-closed lifeboat will quickly produce excessive CO 2 ; Ship radio batteries using VHF are affected by low temperatures. Relevant performance standards of the...
