Fluidized bed furnace device utilizing smoke circulation to dry kitchen garbage

Abstract

The invention discloses a fluidized bed furnace device utilizing smoke circulation to dry kitchen garbage. The fluidized bed furnace device utilizing the smoke circulation to dry the kitchen garbage comprises a drier, a fluidized bed furnace and a feeding device, wherein the fluidized bed furnace is connected with the drier through the feeding device. A kitchen garbage drying device and a kitchen garbage incineration device which are independently arranged are combined into a whole by the smoke circulation, residual heat in the incinerating process is effectively utilized, and the kitchen garbage is ensured to be continuously and uniformly fed into a hearth through the feeding device, so the transshipment storage and the transportation of the kitchen garbage are reduced, and the investment is saved. By adopting the feeding device, the incinerating amount of the kitchen garbage is effectively increased, the overhauling cost and the manual cost are reduced, the running cost is low, the odor generated by the drying of the kitchen garbage enters the hearth to be burnt, and the pollution to the environment is avoided. The fluidized bed furnace device utilizing the smoke circulation to dry the kitchen garbage has the advantages that the structure is simple, the operation is convenient, and the performance is good.

Description

technical field [0001] The invention belongs to the technical field of garbage treatment equipment, and in particular relates to a fluidized furnace device for drying kitchen garbage by using flue gas circulation. Background technique [0002] With the rapid development of the catering industry, the output of kitchen waste is increasing day by day. The average large city produces more than 3,000 tons of domestic waste every day, of which kitchen waste accounts for more than 50%. Food waste generally refers to restaurants and public canteens. Food processing scraps and edible residues in the catering industry and residents' daily life are mainly composed of starch, protein, dietary fiber, animal fat and other organic substances, which have high organic content, high moisture content, perishable odor, etc. The characteristics determine that kitchen waste is both a pollutant and a resource. According to incomplete statistics, the output of kitchen waste in China reached 45 mill...
