Embodiment Construction

[0055] The accompanying drawings are the best embodiments of the fly ash solidification method and solidification device, and the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0056] Fly ash solidification material ratio, fly ash solidification materials include: fly ash, chelating agent and water, in order to further increase the solidification effect of fly ash, enhance the volatile emission and exudation of heavy metals and harmful substances in hazardous waste materials Radiation and soluble radiation have the effect of airway solidification and stability, and the materials used for fly ash solidification also include cement.

[0057] The fly ash solidification method comprises the following steps:

[0058] A. Mixing: Fly ash, chelating agent, water and cement are electronically loaded. According to their ratio, they are input into the mixing system through a metering pump, and the fly ash, chelating agent, wat...

Abstract

The invention relates to a fly ash curing method and device. The fly ash curing method comprises the following steps of mixing materials, specifically, mixing fly ash, a chelating agent, water and cement, and then uniformly stirring the materials; conducting curing operation, specifically, pressing a mixture obtained in the previous step to form blocks; and conducting packaging operation, specifically, packaging the blocks obtained in the previous step. The fly ash curing device comprises a material mixer, a block pressing machine, an automatic stacking system and a packaging device. A discharge outlet of a screw conveyor in the material mixer is in through connection with a mold through hole of the block pressing machine, the discharge end of the block pressing machine is connected with the automatic stacking system through a conveying belt, and the automatic stacking system is connected with the packaging device through a conveying belt. According to the fly ash curing method and device, the fly ash is cured and packaged in an automatic assembly line mode, and the efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a fly ash solidification method and a solidification device. Background technique [0002] At present, with the continuous improvement of national environmental protection management, the kiln industry and the flue gas emission industry have become strict environmental protection management enterprises, and the treatment of fly ash from flue gas emission has also become the focus of current control. Environmental protection improvement, management and control are the main tasks that governments at all levels and social industries urgently need to rectify and replace old and new kinetic energy at present and in the future. [0003] There are currently three methods for the disposal of fly ash hazardous waste: [0004] The first method is the chemical treatment method: through the use of chemical methods for stabilization treatment. The heavy metals i...
