Tidal current energy self-supply circulating system of ship

Abstract

The invention discloses a tidal current energy self-supply circulating system of a ship, and belongs to the field of ship equipment. The tidal current energy self-supply circulating system comprises a pretreatment tank, a high pressure pump, a semi-permeable membrane device, a pressure adjusting valve, a ship body, a water turbine generator, an evaporator and a heat pump air conditioning system, wherein the pretreatment tank is connected with the high pressure pump and the heat pump air conditioning system through a water supply pipe; the high pressure pump is connected with the semi-permeable membrane device through a pipeline; a fresh water outlet and a high-concentration seawater outlet are arranged below the semi-permeable membrane device; the pressure adjusting valve is arranged at the high-concentration seawater outlet to be connected with the evaporator through a pipeline; the evaporator is connected together with a water discharge pipe of the heat pump air conditioning system; and a water turbine generator is arranged on the ship body and is connected with the heat pump air conditioning system, the high pressure pump and the semi-permeable membrane device through wires. The pretreatment tank is connected with a condenser of the heat pump air conditioning system through a water supply pipe to exchange heat; and the water which is subjected to heat exchange is led into the evaporator through the water discharge pipe. According to the system, ocean energy resource is fully utilized, the cost of seawater desalination can be reduced, a large number of conveying equipment are saved, and self-sufficiency of a large amount of substances is realized.
