Embodiment Construction

[0027] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0028] The invention provides a treatment method for deep burial, filling and sealing of urban garbage incineration ash and fly ash.

[0029] The method includes the following steps:

[0030] S1: Pre-process the municipal waste and burn it in a waste incineration power plant, and collect the 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: The granular material prepared in S2 is encapsulated on a granulator;

[0033] S4: Pack the granular material encapsulated in S3 on the granule packaging machine and transport it to the mine that needs to be filled;

[0034] S5: Set the proportions of the part...

Abstract

The invention provides city garbage incineration ash and a treatment method for deep burying, filling and closing of fly ash and belongs to the technical field of garbage treatment. According to the method, filler comes from garbage incineration ash and fly ash, the garbage incineration ash and the fly ash are compressed, pelletized, subjected to particle sealing and particle packaging, and then conveyed to a mine to serve as main aggregate for filling the mine, the ratio of material fly ash particles to other filling materials such as ash particles, an expanding agent, a retaining agent, an accelerator, cement and water according to the strength of a filling body, and after being stirred, the mixture is transported to the gob working face from the ground through filling complete equipmentlike a pipeline to carry out filling. The method can solve the problem that city garbage in China is difficult to treat, and the filling cost of the mine can be saved. The method has the characteristics of turning waste into wealth, being simple in construction technology, low in cost, high in filling body strength, clean and environmentally friendly.

Description

Technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a disposal method of urban garbage incineration ash and fly ash deep buried filling and sealing. Background technique [0002] "Garbage siege" has become a problem that contemporary generations have to face, 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, treating garbage as a usable energy and resource, starting from the ecological industry as a whole, through the integration of information flow, energy flow, and material flow, turning waste treatment into an ecological recycling system will be the future development direction of urban waste treatment. Chinese patent CN201810470793 discloses a method for preparing filler by using grease to decolorize waste soil and incineration of chemical sludge ash. Grease...
