Abstract

The invention discloses an efficient low-pollution treatment method and apparatus of rural waste. The apparatus comprises a waste crusher, a waste dryer, a waste pyrolysis device and a combustor; thewaste crusher is connected to a waste entry of the waste dryer through a waste conveying pipe; a waste discharge pipe of the waste dryer is connected with a waste pyrolysis entry of the waste pyrolysis device; a fuel discharge pipe of the waste pyrolysis device is connected with a fuel entry of the combustor, and a flue gas pipe of the combustor is connected with a flue gas inlet of the waste pyrolysis device; a flue gas outlet of the waste pyrolysis device is connected with a high-temperature flue gas inlet of the waste dryer through a flue gas return pipe. The apparatus has the advantages that the apparatus targets at efficient low-pollution pyrolysis of waste and clean use of energy, and the original waste treatment mode is changed; waste pyrolysis is performed under low oxygen or zerooxygen condition, less oxides of heavy metals are produced, and fewer toxic organic matters are generated and emitted.

Description

technical field [0001] The invention relates to garbage disposal, in particular to a high-efficiency and low-pollution rural garbage disposal method and device thereof. Background technique [0002] Disposal of domestic and production waste of rural residents has always been a difficult problem, and the direct incineration treatment method will even aggravate the smog situation in the north. Municipal solid waste treatment technologies mainly include landfill, composting, and heat treatment technologies. The treatment of rural garbage is still in the backward stage of scattered disposal or incineration. Some garbage is discarded on the roadside and directly exposed to the air, resulting in a messy environment; some garbage is incinerated, billowing black smoke and polluting the atmosphere. [0003] At present, the commonly used waste heat treatment technologies include direct incineration and pyrolysis gasification. Direct incineration is a solid-state heterogeneous combus...
