Ship tail gas treatment device capable of recycling heat energy in multiple stages

Abstract

The invention discloses a ship tail gas treatment device capable of recycling heat energy in multiple stages. The ship tail gas treatment device capable of recycling the heat energy in the multiple stages comprises a recycling box, a temperature difference power generation sheet, a steam collection tank, a filter screen plate and a material dropping groove; a gas inlet pipe is connected to the recycling box through a bolt; a heat insulation pipe is connected to the gas inlet pipe through a bolt; an exhaust fan is connected to a second conical gear through a shaft; the exhaust fan is connectedto the interior of a collection frame through a shaft; the collection frame is mounted on the steam collection tank through a bolt; the steam collection tank is connected to the recycling box througha bolt; and purified water is arranged in the recycling box. The ship tail gas treatment device capable of recycling the heat energy in the multiple stages is provided with the steam collection tank;heat energy radiated by tail gas during passing through the gas inlet pipe can heat the purified water so that hot water for daily use can be provided for a ship; the exhaust fan can pump steam into the steam collection tank to be collected so that convenience can be provided for the follow-up ship heating work; and the heat energy can be utilized in multiple stages so that heat energy resources are effectively saved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship tail gas treatment device capable of performing multi-stage recovery and utilization of heat energy. Background technique [0002] Ships are man-made means of transportation that mainly operate in geographically pure water. With the continuous development of social economy, ships have gradually become the main means of transportation for trade between countries and play a very important role in the development of the global economy. Currently, conventional commercial The main propulsion power of transport ships is mainly low-speed diesel engine. During the running of the ship, the diesel engine will emit a large amount of exhaust gas through the exhaust pipe. As people pay more attention to environmental pollution, the intensity of environmental protection is also increasing. Therefore, the exhaust gas produced by ships must be treated before it can be discharged into the ai...
