Description
Technical Field
The utility model relates to the technical field of industrial waste gas treatment, in particular to a heat accumulating type incineration device.
Background
Due to the rapid development of human beings and the improvement of living standard, the problem of environmental pollution in the society is now endless and spread in all aspects. For example, atmospheric pollution is an example of the pollution in the atmosphere of human life, which is a pollutant that endangers human health. Including particulate matter, suspended matter, and Volatile Organic Compounds (VOCs). Among them, Volatile Organic Compounds (VOCs) are precursors that form photochemical smog and haze smog, and most VOCs have toxicity and carcinogenicity because they have highly harmful effects on the liver, kidney, brain, and nervous system of humans.
VOCs are mainly derived from industrial production. At present, the industry isThe method for treating pollutants discharged in the atmosphere comprises the following steps: absorption, adsorption, condensation, combustion, biological and membrane separation, low-temperature plasma, photocatalytic oxidation, catalytic incineration, and the like. Among the common methods for VOCs waste gas in industry are absorption, adsorption, condensation, regenerative incineration, etc. Different treatment processes are selected according to the physicochemical properties of pollutants in the waste gas, and a regenerative incineration method is adopted for various complex VOCs components. The regenerative incineration method can convert various volatile organic compounds into CO2And H2And O. Can ensure that the gas at the outlet reaches the standard and is discharged.
In the prior art, the heat accumulating type incinerator is mainly a tower type incinerator and a cylinder type incinerator. Three-chamber regenerative incinerators are most commonly used in tower incinerators. The basic principle of the tower-type heat accumulating type incinerator is that organic waste gas is heated by a first heat accumulating chamber, and the heated waste gas is combusted and decomposed in a hearth to be decomposed into micromolecular substances. The decomposed substances enter a second heat storage chamber, heat is transferred to the heat storage body, and the heat is discharged after being cooled. And blowing the third regenerator, and blowing the purified gas of the residual untreated waste gas remained on the heat accumulator back to the hearth for incineration treatment. The steps are circularly carried out. The energy conservation and the effective degradation of the waste gas are ensured.
However, the existing regenerative incinerator still has the problem of excessive energy consumption in practical application, and the actual natural gas consumption is far higher than the theoretical natural gas consumption. The main reason is that in the actual monitoring and control, the temperature control is performed according to the average temperature as the basis for judging whether the temperature is increased or decreased, and the method has certain loopholes. Resulting in excessive consumption of fuel. Directly influences the energy-saving concept of environmental protection and greatly improves the operation cost of enterprises.
