Problems solved by technology
[0003] The existing garbage fly ash disposal process is mainly divided into three steps: washing, pulping and molding. The washing is to remove the salt ions contained in the fly ash, such as chloride ions. Chlorine is one of the main conditions for the formation of dioxins. First, dechlorination can effectively prevent the formation of dioxins, and the main method of dechlorination is to remove them by washing. The application number CN201610096454.2 proposes a fly ash desalination washing device through a membrane conveyor belt to receive fly ash, and Water is sprayed on the fly ash, and a vacuum is set at the bottom of the filter membrane to suction and dehydrate the water. This method is technically difficult to implement, because the sealing problem between the vacuum box and the filter cloth is difficult to solve, and only The sufficient mixing of water and fly ash is not achieved through spraying, and the washing efficiency is not high

Embodiment Construction
[0037]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0038] Such as Figure 1 to Figure 12 As shown, in the embodiment of the present invention, a waste fly ash resource disposal equipment includes the following steps:
[0039] Step 1: Use bucket elevator or conveying auger to put the fly ash into the lower silo, inject the water mixed with dechlorination agent into the lower silo through the water injection port at a uniform speed, and add it to one-third of the volume of the mixing silo , then reduce the water...

The invention belongs to the technical field of garbage fly ash treatment, and discloses a resource disposal method of garbage fly ash. Inject the water that has been mixed with dechlorination agent into the lower hopper at a constant speed until it fills up to one-third of the volume of the mixing silo, then reduce the water injection rate, start the No. 1 motor, and the fly ash in the lower hopper is transported to the mixing silo while being stirred. The present invention can unload the material in the unloading bin through the conveying auger, and control the discharge speed of the water-ash mixture in the mixing bin through the cut-off valve pair, and reach a balance with the unloading speed above, so it is in the mixing bin In the inner cavity of the machine, a stable balance of three states of feeding, discharging and stirring is formed, which can not only achieve water-cement mixing, but also continue to feed, so that the water-cement mixture can continuously reach the next process for processing.
Description
technical field [0001] The invention belongs to the technical field of waste fly ash treatment, and in particular relates to resource disposal equipment for waste fly ash. Background technique [0002] Garbage fly ash mainly refers to the tiny particles formed after garbage is incinerated. Reasonable disposal methods can turn waste into treasure and make building materials. [0003] The existing garbage fly ash disposal process is mainly divided into three steps: washing, pulping and molding. The washing is to remove the salt ions contained in the fly ash, such as chloride ions. Chlorine is one of the main conditions for the formation of dioxins. First, dechlorination can effectively prevent the formation of dioxins, and the main method of dechlorination is to remove them by washing. The application number CN201610096454.2 proposes a fly ash desalination washing device through a membrane conveyor belt to receive fly ash, and Water is sprayed on the fly ash, and a vacuum is...
