Equipment and process for preparing soil conditioner from fly ash

Abstract

The invention discloses equipment and a process for preparing a soil conditioner from fly ash. The equipment comprises a first conveyor, a first crusher, a first closed conveyor, a first closed screening machine, a first returned material conveyor, a second closed conveyor, a fly ash bin, a high-pressure roller press, a scattering and granulating machine, a screening machine, a returned material conveyor, a quantitative packaging machine, a finished product warehouse, a second feeder, a humic acid bin, a fourth closed conveyor, a second returned material conveyor, a second closed screening machine, a fifth closed conveyor, a second crusher, a second conveyor and an automatic control device. According to the equipment and the process for preparing the soil conditioner from the fly ash, the prepared fly ash soil conditioner can be applied for a long time, the soil hardening problem is solved, trace elements necessary for crops can be supplemented, and the fly ash soil conditioner prepared by the equipment and the process for preparing the soil conditioner from the fly ash not only reduces environmental pollution, but also can create higher economic benefits.

Description

technical field [0001] The invention relates to the field of fly ash utilization, in particular to equipment and technology for making soil improver from fly ash. Background technique [0002] Fly ash refers to the fine ash collected from the flue gas after coal combustion, and is the main solid waste discharged from coal-fired power plants. If a large amount of fly ash is not treated, it will generate dust and pollute the atmosphere; if it is discharged into the water system, it will cause river silting, and the toxic chemicals in it will cause harm to human body and organisms, but fly ash can be used as a resource. Such as as a concrete admixture, etc. [0003] The fly ash discharged by a large number of coal-fired boiler power plants in Xinjiang is in the millions of tons every year. Due to the inability to make full use of it, it has accumulated hundreds of millions of tons of fly ash, and the amount of fly ash used as a resource is only About 30%, it not only wastes t...

Problems solved by technology

[0003] The fly ash discharged by a large number of coal-fired boiler power plants in Xinjiang is in the millions of tons every year. Due to the inability to make full use of it, it has accumulated hundreds of millions of tons of fly ash, and the amount of fly ash used as a resource is only About 30%, not only wasting the land resources used for stacking fly ash, but also seriously polluting the surrounding environment
