Problems solved by technology

The above methods all need to use a set of mechanical mixing facilities. After the configured fly ash and cement or chemical agents are fully mixed through the mixing facilities, they are sent to the landfill pit through conveying and transportation equipment. Using the above methods, corresponding storage facilities are also required. Equipment for receiving and storing fly ash and cement or chemicals, so the traditional fly ash stabilization fly ash disposal method needs to build a stabilization workshop next to the landfill pit to carry out the above operations

Embodiment 1

[0023] As shown in Figure 1, firstly, the fly ash of the incineration plant is loaded into a special tank transport vehicle, and directly transported to the flow ash storage tank located beside the landfill pit, and the fly ash loaded in the vehicle is passed through the vehicle by the on-board compressor. The ash conveying pipeline and feed port 1 are directly pressed into the fly ash storage tank. The fly ash storage tank is composed of a cylindrical storage tank 3 and a conical storage tank 4 from top to bottom in order to store more fly ash, and more Effective disposal of fly ash. A safety door 2 is provided on the upper part of the fly ash storage tank to balance the atmospheric pressure and ensure that the storage tank works under a safe pressure. The lower conical storage tank 4 is provided with an inflatable plate 5 . The screw conveyor adjusts the speed of the solid screw shaft 10 and sheet screw shaft 12 of the screw conveyor by connecting the motor 7, the gearbox 8...

Abstract

A method for stabilizing the fly ash generated by incinerating garbage includes such steps as loading the fly ash in a tank truck, directly transporting it to the movable storage tank close to a burying pit, pneumatically delivering the fly ash into said storage tank, delivering the fly ash from the bottom of tank into said burying pit via a screw conveyer while spraying liquid chemical, mechanical spreading in pit, and tampering.

Description

Technical field: [0001] The invention relates to a treatment device for domestic waste incineration fly ash, in particular to a process method for stabilizing the domestic waste incineration fly ash. Background technique: [0002] According to the relevant national regulations, the flue gas produced by the incineration of domestic waste cannot be directly discharged into the atmosphere. It must be collected by the flue gas purification system to capture the fly ash containing various toxic and harmful components, so that the gas purification can reach the standard. To be discharged through the chimney to ensure that the environment is not polluted. Since the fly ash captured during the purification process contains heavy metals, harmful organic substances, such as dioxins, furans, etc., and other harmful substances, the fly ash from domestic waste incineration is classified as hazardous waste. Special disposal must be carried out according to national regulations. [0003]...
