Embodiment Construction

[0030] Such as figure 1 Shown is a chelating agent preparation system, comprising a chelating agent preparation device 11, a chelating agent storage tank 12, a chelating agent delivery pump 13, and the chelating agent preparation device 11 is used to dilute the chelating agent into a certain concentration solution; the chelating agent storage tank 12 stores the chelating agent The solution prepared by the mixture preparation tank; the chelating agent delivery pump 13 completes the delivery of the chelating agent solution;

[0031] The chelating agent preparation device comprises a chelating agent stirring tank 111 and a chelating agent solution pump 112, and the substances added in the chelating agent stirring tank 111 are chelating agent and process water. The source of process water comes from the tap water pipe network of the factory.

[0032] The filling chelating agent is added to the chelating agent dosing pump, sent to the chelating agent stirring tank to be stirred wi...

Abstract

A system for treatment of fly ash from waste incineration comprises an electrical system and an automatic control system and further comprises a chelating agent preparation system, a fly ash stabilization system and a ton bagging machine system. The system has the benefits as follows: compared with the prior art, the system has the advantages that the degree of automation is high, fly ash captured in a flue dust remover (a bag-type dust remover) is fed into an fly ash storage tank which is designed according actual waste incineration quantity through a vulcanization bottom bin in an air cushion conveying manner, and treated into cured mixtures through a series automatic treatment during production, and the cured mixtures are transported out to be backfilled after bagging; according to the system, a measuring tank is adopted for controlling material usage, so that the ratio of used materials is accurate, the fly ash treatment efficiency is high, moreover, manpower is saved; equipment operation is convenient and safe; multiple controller are arranged to control middle processes, so that feedback in time and disposal in time are realized when one link in the system exceeds a preset specification.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a waste incineration fly ash processing system. Background technique [0002] Due to the fast processing speed of domestic waste incineration, small footprint, and significant reduction and harmlessness effects, the preferred method of waste disposal in my country is landfill after incineration. However, the fly ash after garbage incineration contains a variety of harmful metal substances and salts such as Cd, Pb, Cu, Zn, and Cr in relatively high concentrations that can be leached by water. The "National Hazardous Waste List" has clearly stipulated Ash is hazardous waste, and the disposal of fly ash must be carried out in strict accordance with the standards of hazardous waste. [0003] At present, a more convenient and effective method for fly ash disposal is solidification and stabilization. Cement solidification, asphalt solidification, melt solidification technolog...
