Embodiment Construction

[0027] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0028] The invention provides a treatment method for deep-buried filling and sealing of municipal waste incineration ash and fly ash.

[0029] The method includes steps as follows:

[0030] S1: Incinerate municipal waste in a waste incineration power plant after pretreatment, and collect ash and fly ash after incineration;

[0031] S2: Compress the incineration ash and fly ash collected in S1 on a compression-granulator to make granular materials that meet the requirements;

[0032] S3: encapsulating the granules prepared in S2 on a granulator;

[0033] S4: Pack the granules packaged in S3 on the granule packaging machine and transport them to the mines that need to be filled;

[0034] S5: Mix the granules packaged in S4 with expansion agent, retarder...

Abstract

The invention provides a deep-buried, filled and sealed disposal method for municipal waste incineration ash and fly ash, which belongs to the technical field of waste treatment. The filling material of this method comes from waste incineration ash and fly ash, which is compressed-granulated, sealed, and granulated by compressing the waste incineration ash and fly ash, and then transporting it to the mine as a filling material for the mine. As the main aggregate, the material fly ash particles and ash slag particles, expansion agent, retarder, accelerator, cement, water and other filling materials are set according to the strength of the filling body, and after stirring, the complete set of equipment is filled through pipelines, etc. The ground is transported to the working face of the goaf for filling. This method can solve the problem of difficult disposal of urban garbage in my country, and can save filling costs for mines. The invention has the characteristics of turning waste into treasure, simple construction technology, low cost, high filling body strength, clean and environment-friendly, and the like.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a disposal method for deep burial filling and sealing of municipal garbage incineration ash and fly ash. Background technique [0002] "Garbage besieged city" is a problem that has to be faced in contemporary times, and garbage disposal has become a headache for city managers everywhere. Traditional garbage disposal methods have caused irreparable and serious consequences to the city and its surrounding environment. Therefore, regarding waste as available energy and resources, starting from the overall ecological industry, through the integration of information flow, energy flow, and material flow, turning waste treatment into an ecological cycle system will be the development direction of urban waste treatment in the future. Chinese patent CN201810470793 discloses a method for preparing filler by using oil decolorization waste soil and chemical sludge incineration ash...
