Embodiment Construction

[0027] Below is working principle and working process of the present invention:

[0028] Before incineration in the waste incinerator, according to the heat capacity of the shaped high-temperature composite phase-change thermal storage material 3, determine the total power of the four electric heating tubes 9, and simultaneously electrify the four electric heating tubes 9, and heat for 5 minutes to make the shaped high-temperature composite phase-change thermal storage material 3. About 50% of the high-temperature phase-change thermal storage materials are transformed into liquid at 850°C, and then start to incinerate garbage.

[0029] The holding cylinder 4 has five vertical column holes for passing the flue gas and using the shaped high-temperature composite phase change heat storage material 3 to heat the flue gas below 850°C to make the flue gas 850°C. According to the flow rate of the flue gas, the height of the vertical column hole ensures that the flue gas stays in the ...

Abstract

The invention relates to a device for constant high-temperature treatment prior to garbage incineration and flue gas purification. After garbage is incinerated by a garbage incinerator, according to a generated flue gas treatment process, dioxin components in flue gas are removed under a constant high-temperature state, and subsequent flue gas purification treatment is carried out. The device is used for a constant high-temperature removal process of the dioxin components in the flue gas, and belongs to the application range of the garbage incinerator in the technical field of boilers. The flue gas is heated by using a shaped high-temperature composite phase-change heat storage material, the isothermal phase change temperature of the shaped high-temperature composite phase-change heat storage material is 850 DEG C, feedback is carried out by virtue of a flue gas heat sensor, the shaped high-temperature composite phase-change heat storage material is automatically and electrically heated prior to garbage incineration or under the condition that the temperature of the flue gas is lower than 850 DEG C, the staying time of the flue gas in a high-temperature pipeline being 850 DEG C is controlled to be longer than 6s, the staying time of the flue gas being 850 DEG C is farther longer than the staying time, namely 2s, specified by national standards, and the dioxin components in the flue gas are thoroughly removed.

Description

Technical field: [0001] The invention relates to a constant high-temperature treatment device before purification of waste incineration flue gas. After incineration in the garbage disposal furnace, for the treatment process of the flue gas, the dioxin components in the flue gas are firstly removed at a constant high temperature, and then the flue gas purification treatment is carried out later. The invention is a process for removing dioxin components in flue gas at a constant high temperature, and belongs to the application range of garbage incinerators in the technical field of boilers. Background technique: [0002] Municipal solid waste incineration has also brought serious environmental pollution. Waste gas emitted by waste incineration contains high concentrations of acid gases, heavy metals, dioxins and other highly toxic organic pollutants. For this reason, many developed countries have formulated Strict waste incineration pollutant emission standards. According to...
