Description

A multifunctional integrated furnace for simultaneous pyrolysis of waste and enhanced combustion

technical field

The utility model relates to the field of garbage disposal, in particular to a multifunctional integrated furnace for synchronous pyrolysis of garbage and enhanced combustion.

Background technique

At present, incineration and landfill are mostly used in my country's garbage disposal methods. Due to the characteristics of low calorific value and high water content of domestic garbage in my country, when incineration method is used, a certain amount of fuel needs to be added to the garbage to promote garbage incineration. Waste of energy, and higher requirements for temperature control during the incineration process, waste incineration produces a large amount of dioxins and furans; using landfill to dispose of waste, in addition to the unpleasant odor generated during the landfill process, the Leachate is a difficult problem in landfill technology. The production of leachate seriously pollutes groundwater and endangers human survival.

Pyrolysis is the process of using the thermal instability of organic matter (hydrocarbons) to chemically decompose organic matter by heat. Pyrolysis can be understood as the first step of gasification and combustion, and the process is carried out under anaerobic or anoxic conditions. Therefore, pyrolysis is different from combustion, which requires sufficient oxygen. Pyrolysis is simply defined as a substance in which hydrocarbons reach a high temperature in an oxygen-deficient environment and decompose into their chemical element components. When the gases produced by pyrolysis are cooled to room temperature, the heavier gases condense into a liquid, called bio-oil, and the lighter gases, such as hydrogen and methane, are called syngas. By changing the pyrolysis temperature and duration, the pyrolysis process can be optimized and the proportions of syngas, bio-oil and bio-char generated can be adjusted. For example, slow pyrolysis at lower temperatures produces more biochar, while fast pyrolysis at higher temperatures produces more syngas. Through rapid pyrolysis, the resulting syngas can be burned in the system to maintain the pyrolysis temperature, leaving only a small amount of biochar as the product after pyrolysis. In the process of waste pyrolysis, the heat utilization is insufficient, the energy is uncontrollable, and the difference in pyrolysis temperature will cause problems such as different pyrolysis products.
