A carbon-containing residue reduction method and device thereof

Abstract

The invention discloses a carbon-containing residue reduction method and a device thereof. Carbon-containing residue is put into a microwave oven cavity, the microwave heating method is adopted to enable the temperature to rise to 1100 DEG C to 1200 DEG C, firing continues to be carried out for 30 minutes to 40 minutes, the carbon-containing residue is converted into high-temperature smoke and solid substances with the stable property, and the high-temperature smoke is led into a heat recycling system; a boiler system (9) is arranged on the upper portion, the generated high-temperature smoke is subject to heat recycling and utilizing, a microwave firing device is arranged on the lower portion, and the carbon-containing residue is subject to high-temperature firing; the microwave firing device comprises a feeding microwave suppressor (7), a microwave heating firing furnace (6) and a discharging microwave suppressor (10); and according to the heating mechanism, microwave heating is utilized, volatile matter is not needed, combustible oil is not needed to be added, the controllable degree is high, and no environmental pollution exists. According to the carbon-containing residue reduction method and the device therefore, the cauterant decrease of the industrial chemical waste residue can be reduced to 20% or below, the environment is not polluted, meanwhile, the heat is recycled, the carbon-containing residue reduction method and the device are controllable and clean, and the heat can be effectively utilized.

Description

technical field [0001] The invention relates to a carbon-containing residue reduction method. The invention also relates to a device for realizing the carbon-containing residue reduction method. Background technique [0002] Carbonaceous residue is a kind of chemical waste residue without volatile matter, and its calorific value is 3000 kcal / Kg. Loss on ignition refers to the loss on ignition after the waste residue is incinerated. Chemical waste residues contain carbon and various organic and inorganic substances, which are toxic and will pollute the soil after landfilling. The method of incineration is to let the combustible components in the waste residue react violently with the oxygen in the air. After full combustion, the solid residue can be directly landfilled. [0003] The current way to deal with this carbon-containing chemical residue is to use a rotary kiln for incineration, but the combustion is not sufficient. The solution is to add combustible fuel oil to...

Problems solved by technology

[0003] The current way to deal with this carbon-containing chemical residue is to use a rotary kiln for incineration, but the combustion is not sufficient

The solution is to add combustible fuel oil to the waste residue to support combustion, and increase the length of the kiln to increase the burning time. Some kiln lengths have been increased to more than 40 meters, but they still cannot meet the landfill standard (national regulations: waste residue can be landfilled) Loss on ignition must be less than 2%)

At the same time, due to the addition of combustible fuel oil to the waste residue, the gas after combustion has polluted the environment.

The calorific value of carbon-containing residue is generally 3000 kcal / Kg, and it is incinerated in a rotary kiln, which is a great waste of heat
