The invention discloses a device for drying ship garbage by using waste heat of smoke of a marine incinerator. The device comprises an incinerator, a combustor, a smoke pipe and a garbage drying box, wherein a heat-conduction oil heat release cavity which is used for bearing and heating garbage is formed in the middle of the garbage drying box; a heat-conduction oil heat absorption pipe is arranged on the outer layer of the smoke pipe; one end of the heat-conduction oil heat release cavity is connected with a heat-conduction oil inlet pipeline of the heat-conduction oil heat absorption pipe; and the other end of the heat-conduction oil heat release cavity is connected with a heat-conduction oil outlet pipeline of the heat-conduction oil heat absorption pipe. The garbage drying box, the heat-conduction oil heat release cavity and the heat-conduction oil heat absorption pipe arranged on the outer layer of the smoke pipe are organically combined, so that a garbage drying system is formed; heat-conduction oil is heated by the smoke, and circulates continuously through a pipe, heat absorption and heat release on the heat-conduction oil are finished, and finally, moist garbage is dried; and the dried garbage is conveyed in the incinerator body, and is combusted sufficiently. Compared with the existing electric heating drying system, the device is energy-saving.
Description
technical field [0001] The invention relates to the recovery and utilization of waste heat of flue gas, in particular to a device for drying ship garbage by utilizing the waste heat of flue gas of a marine incinerator. Background technique [0002] The problem of marine environmental pollution is an urgent problem to be solved at home and abroad. Ships generate ship garbage during their voyages. Correct disposal of such garbage can reduce marine ecological pollution and take the road of ecological sustainability. As the main means of freight transportation, ships have limited cabin space. Directly discharging overboard will seriously affect the marine environment, and if it is not handled in time, it will take up a lot of space and increase operating costs. Nowadays, most ocean-going ships are equipped with marine incinerators, which can incinerate ship garbage. Generally, the temperature of flue gas at the outlet of marine incinerators can reach above 300°C, but the wast...
