Description

Secondary chelating treatment device for fly ash

Technical Field

The utility model belongs to the field of environmental protection of hazardous waste disposal, and particularly relates to a fly ash secondary chelating treatment device.

Background

Fly ash is a harmful substance generated in the process of incinerating garbage in a garbage incineration power plant. The fly ash produced after combustion has become more versatile in its composition due to the wide variety of waste burned. At present, the treatment method commonly adopted for the waste incineration fly ash in China comprises the following steps: the fly ash after the stabilization treatment is packaged by a ton bag and is sent to a curing room for temporary curing, sampling detection is carried out during the curing period, qualified landfill is detected, and secondary chelating treatment is carried out if unqualified. However, during the curing process, the moisture evaporates, so that a large-hardness integral block is easily formed in the ton bag, and the block is not easily smashed manually.

With the continuous improvement of the requirements of environmental assessment and the continuous update of pollution control standards of household refuse landfill, a plurality of refuse incineration power plants are not provided with a secondary chelating system in the initial stage of construction, so that effective and timely secondary chelating treatment cannot be carried out after unqualified fly ash is detected in the operation process in the later stage, and the original fly ash stabilizing system cannot be reasonably modified due to the limitations of installation space, transportation conditions and the like. The lack of a mating secondary chelation treatment system can make the secondary chelation treatment very difficult.

The existing secondary chelating treatment process comprises the following steps:

the first way is: before the ton bags enter the bale breaker, the ton bags are sent to a loosening machine for loosening operation through a transfer forklift, after the whole block materials are broken up, the whole block materials are then transported to the bale breaker through a transfer forklift, the ton bags are sent into the bale breaker through a lifting device, and after the ton bags are unpacked in the bale breaker, the materials in the ton bags are discharged;

the second way is: before the ton bag enters the unpacking machine, the whole block in the ton bag is scattered by manually holding an electric pick or an impact drill (but the ton bag is extremely easy to break in the smashing process to cause the material to scatter on the ground or contact with people), then the ton bag is transported to the unpacking machine through a transporting forklift, the ton bag is sent into the unpacking machine by a lifting device, and after unpacking operation is carried out in the unpacking machine, the material in the ton bag is discharged;

compared with the prior art, the problems of the prior art that the old project reforms the secondary chelating treatment system are as follows:

1. because the loosening machine and the unpacking machine are arranged separately, when the ton bag unpacks in the unpacking machine, the earlier stage loosening machine is not in place, and large materials exist in the discharged materials, so that the materials are difficult to discharge and cannot be subjected to secondary loosening operation, manual auxiliary mashing is needed, the risk that the materials are contacted with people exists when the manual operation is needed, and time and labor are wasted;

2. because the loosening machine and the bale breaker are arranged separately, and the transfer of the ton bags is carried out, the occupied area is larger, and the transformation of the old project cannot be satisfied.
