Problems solved by technology

[0002] The basic goal of pollutant treatment is harmlessness, reduction and recycling (abbreviation: three modernizations). Garbage is one of the main sources of environmental pollution. Currently, incineration of waste to generate electricity is a common way to solve waste pollution. The existing project is to All the garbage is sent to the furnace for incineration. According to the requirements of relevant standards, the temperature of the furnace should not be lower than 850°C, and the time for the flue gas to pass through this temperature range should not be less than 2s. In order to meet the above requirements, when the calorific value of the garbage is low, it is necessary to add combustion support (such as: coal, fuel oil, natural gas, etc.), which increases energy consumption and operating costs, and the greater the amount of incineration, the greater the amount of exhaust gas emissions

Abstract

The invention discloses a waste incineration improved process comprising the following step 1 of performing sorting treatment to wastes, and obtaining perishable organic matters and comburents; the step 2 of putting the comburents into an incinerator for incineration power generation; and the step 3 of degrading the perishable organic matters by using aerobes, and converting the organic matters into organic materials. The problems that the heat value of materials added to a furnace is low, and combustion-supporting materials need to be added; and the operating cost is high and the overall benefit is poor are solved. According to the improved process, the overall heat value of remaining wastes after sorting can be improved greatly, and the wastes are conveyed into the furnace and burnt quickly; the combustion-supporting materials (coal, fuel, natural gas and the like) are not required; not only are energy sources saved, but also the operating cost is reduced; not only is the amount of the wastes added to the furnace reduced, but also the combustion-supporting materials are not required; the emission of waste gas is reduced greatly, and pollution to environment by atmospheric pollutants is reduced; the cost for waste gas purification and treatment is decreased; and the problems that the heat value of the materials added to the furnace is low and the combustion-supporting materials need to be added; and the operating cost is high and the overall benefit is poor are solved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to an improved process for waste incineration. Background technique [0002] The basic goals of pollution control are harmlessness, reduction and resource utilization (referred to as: three chemical processes). Garbage is one of the main sources of environmental pollution. Currently, waste incineration for power generation is a common way to solve waste pollution. All the garbage is sent to the furnace for incineration. According to the relevant standard requirements, the furnace temperature should not be lower than 850 °C, and the time for the flue gas to pass through this temperature zone should not be less than 2s. In order to meet the above requirements, when the calorific value of the garbage is low, it is necessary to add combustion support (such as: coal, fuel oil, natural gas, etc.), which increases energy consumption and operating costs, and the greater the...
