Problems solved by technology

[0010] The present invention can remove the chloride ions in the fly ash by using the garbage disposal system combined with the process of the present invention, thereby solving the negative impact of the currently existing chloride salt on the process of co-processing of cement kilns. At the same time, the process can also Using this system to turn harmful substances in fly ash into chemical products not only solves the pollution problem of fly ash, but also produces certain economic benefits. While producing economic benefits, it also reduces the current imperfect treatment of fly ash high cost

Embodiment

[0059] A garbage fly ash treatment system, such as figure 1 As shown, it includes two parts: the fly ash washing system and the wastewater treatment system; the fly ash is firstly washed by the fly ash washing system, and then the solid-liquid separation is carried out, and then the separated solid sludge and wastewater are treated separately;

[0060] specific as figure 2 and image 3 As shown, as follows:

[0061] The fly ash washing system in the garbage fly ash treatment system adopts a multi-stage cleaning pool 2 arranged in sequence and cooperates with a multi-stage washing filter press 4. The fly ash washing system is provided with a reaction storage pool for storing the washed waste water 304; the wastewater stored in the reaction storage tank 304 is used for further treatment in the subsequent wastewater treatment system; the water washing filter press 4 separates the mixed solution obtained from the cleaning tank 2 of each stage;

[0062] The waste water treatmen...

Abstract

The invention relates to the technical field of waste fly ash treatment, in particular to a waste fly ash treatment system and a treatment process. The waste fly ash treatment system comprises a fly ash water washing system and a wastewater treatment system; and the waste fly ash is subjected to distributed treatment through a two-step process, so that treated fly ash cannot achieve a negative effect on cooperative treatment of a cement kiln.

Description

technical field [0001] The invention relates to the technical field of garbage fly ash treatment, in particular to a garbage fly ash treatment system and a treatment process. Background technique [0002] With the rapid development of urbanization, the output of domestic waste in my country has increased year by year, from 189 million in 2013 to 206 million tons in 2015. The proportion of incineration disposal is increasing year by year. Fly ash is an inevitable product of waste incineration, accounting for about 3-5% of the amount of waste incinerated. According to this calculation, the fly ash produced by waste incineration nationwide will be 10,000-20,000 tons / day in the future. Such a large amount of fly ash is generated, making how to safely and effectively dispose of incineration fly ash has become an urgent environmental and social problem to be solved. [0003] Fly ash is the fine particulate matter collected in the flue gas purification system, including the fly a...
