The invention discloses a circulating type energy station with functions of preventing dampness and preventing corrosion and belongs to the technical field of energy stations. The circulating type energy station comprises a protecting shell and an anti-vibration layer at the bottom of the protecting shell and is characterized in that an energy generator, an energy conversion device and an energy supply device which are sequentially connected are arranged in the protecting shell; the energy generator comprises a biological fermentation storage tank, a waste liquid tank is arranged below the biological fermentation storage tank, a biogas digester and an energy conversion device which are parallelly connected are arranged on the right side of the biological fermentation storage tank, and a fuel gas chamber is connected to the right side of the biogas digester and connected with the energy conversion device; the energy supply device is connected to the right side of the energy conversion device and comprises an energy storage device and an energy utilization device, and the energy utilization device penetrates the outer wall of the protecting shell. The circulating type energy stationhas the advantages that the whole energy station is protected by the protecting shell, microbial fermentation energy is used as the fuel gas and converted into electric energy to be sufficiently utilized, a dampness preventing effect is achieved by the multilayer dampness-preventing structure, and facility mildewing in the energy station is also reduced.
