Ship waste heat heating system and method based on heat pipe waste heat economizer

Abstract

The invention provides a ship excess heat heating system and method based on a heat pipe excess heat economizer. The ship excess heat heating system is optimized based on the heat pipe excess heat economizer; the automation level is improved; the control problem of aN excess heat utilization system in the condition of a changing working condition and changing load can be solved; and low temperature corrosion due to smoke can be avoided. The main principle of the system are that after the heat pipe excess heat economizer is heated by smoke, the temperature of a hot water outlet of the heat pipe excess heat economizer is about 85 DEG C, firstly, air conditioning circulating water is heated by a circulating water excess heat utilization device, and then water in a electrical heating washing water tank is heated by a washing water plate type heat exchanger, and the return water temperature is 25 DEG C after the excess heat is utilized.

Description

technical field [0001] The invention belongs to the field of energy saving and emission reduction of surface ships, and in particular relates to a ship waste heat heating system and method based on a heat pipe waste heat economizer. Background technique [0002] The heat pipe type waste heat economizer can realize the efficient replacement of the exhaust heat energy of the prime mover. However, the exhaust heat energy of the prime mover and the heating load of the whole ship are constantly changing. Variable load conditions and heat mismatch are common phenomena in the utilization of ship waste heat. The traditional ship waste heat utilization system has a low level of automation, and often needs to add hot wells, cooling seawater pumps and other equipment. In summer and other conditions where heat is not used, it becomes an energy-consuming system instead, which does not achieve the desired energy-saving and emission-reduction effects. .
