Abstract

The invention discloses a film drying system and method for exhausting flue gas waste heat through garbage incineration to dry garbage. The film drying system comprises a heat exchanger and a stacking bin. The heat exchanger is provided with a flue gas exhaust inlet and a flue gas exhaust outlet communicating with the flue gas exhaust inlet. The flue gas exhaust inlet is provided with a flue gas exhaust pipe communicating with a flue gas exhaust chimney. The heat exchanger is provided with an air inlet and an air outlet communicating with the air inlet. Multiple parallel ventilating pipelines are arranged at the bottom of the stacking bin and communicate with the air outlet, and the top of the stacking bin is covered with a biological drying film in sealing fit. Nozzles for spraying air into the stacking bin are arranged on the ventilating pipelines, and the stacking bin is provided with a leachate recovery device capable of enabling the outlet ends of the ventilating pipelines to communicate with the stacking bin. The film drying system and method exhaust the flue gas waste heat through garbage incineration to dry the garbage, so that it is avoided that stinks are exhausted in the drying process, and the drying period of the garbage is shortened.

Description

technical field [0001] The invention belongs to the field of garbage drying, and in particular relates to a membrane drying system and method for drying garbage by using the residual heat of flue gas discharged from garbage incineration. Background technique [0002] With the rapid development of the domestic economy and the improvement of the consumption level of residents in recent years, the production of domestic life has increased year by year. Since domestic garbage is collected in a mixed manner, the garbage generally has the characteristics of high moisture content, low calorific value, and high organic content of kitchen waste. The harmless treatment of garbage has become one of the serious problems that plague urban development. [0003] At present, resource treatment and garbage incineration technology are one of the ways to quickly realize the harmless treatment of garbage. When dealing with garbage with high water content, the additional moisture in the garbage ...
