Furnace for combined combustion of methane of garbage leachate and garbage

Abstract

The invention relates to a furnace for combined combustion of methane of garbage leachate and garbage and belongs to the technical field of combustion equipment. The furnace comprises a steel frame, a furnace grate, a furnace chamber and a tail flue pipe. The furnace chamber is connected with the tail flue pipe, the furnace chamber is made up of a hearth, a combustion chamber and three flue pipes, the furnace grate is arranged on the lower part of the furnace chamber, and a slag and ash discharging device is arranged below the furnace grate. The furnace is characterized in that a methane burner of the garbage leachate is mounted on a side wall of the lower part of the hearth above the furnace grate, and superheaters are arranged in the three flue pipes and the tail flue pipe. Considering the features of various fuels, the methane of the garbage leachate and garbage are burned mixedly, and accordingly the furnace is an energy-saving and environment-friendly comprehensive furnace.

Description

technical field [0001] The invention belongs to the technical field of combustion equipment, and in particular relates to a boiler for mixed combustion of biogas of landfill leachate and waste. Background technique [0002] Landfill leachate is high-concentration organic wastewater produced during the stacking process of domestic garbage due to the decomposition of microorganisms, the leaching of rainwater, and the long-term immersion of surface water and groundwater. Landfill leachate contains a large amount of harmful substances, and if it is discharged indiscriminately, it will cause serious pollution to the environment, so it needs to be collected and undergo a series of treatments to meet the discharge standards before it can be discharged. During the collection and treatment of landfill leachate, a large amount of biogas will be produced. The biogas of landfill leachate is a kind of available energy. After being collected, it enters the boiler furnace through a spec...

Problems solved by technology

China's invention patent application "A Garbage Incineration Boiler", the application number is 201010210189.9, discloses a technical solution for a garbage incineration boiler. Although an auxiliary burner is designed in the technical solution, there is no specific matching structure for the auxiliary burner. Moreover, the biogas of landfill leachate is a special kind of biogas, which requires special structural settings. Therefore, there is currently no comprehensive boiler for the mixed combustion of landfill leachate biogas and domestic waste in the market.
