Detailed Implementation

[0020] The following detailed description of preferred embodiments of the present invention, along with the included examples, will make the content of the present invention more readily understood. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In case of any conflict, the definitions in this specification shall prevail.

[0021] Example 1:

[0022] Provided such as Figure 1 The illustrated fly ash pollutant degradation and co-energy storage device includes: a fly ash storage silo 1, a conveying device 2, and a fly ash heat exchange silo 3. The fly ash storage silo 1 and the fly ash heat exchange silo 3 are connected by the conveying device 2, which is used to transport fly ash from the fly ash storage silo 1 to the fly ash heat exchange silo 3. Both the fly ash storage silo 1 and the fly ash heat exchange silo 3 are externally equipped with heat insulation panels. The fly ash storage silo 1 and the fly ash heat exchange silo 3 are insulated and heat-resistant concrete structures with a 15cm wear-resistant and fire-resistant layer inside to facilitate high-temperature treatment of fly ash. The external heat insulation panels are used to reduce heat loss.

[0023] A temperature sensor 11 and a resistance heating device 12 are installed inside the fly ash storage silo 1. A feed inlet 13 is located at the top of the fly ash storage silo 1. A first gate 14 is located at the bottom of the fly ash storage silo 1. The feed inlet 13 is equipped with a valve, which opens during feeding and closes after feeding. The temperature sensor 11 and the resistance heating device 12 are electrically connected. The temperature sensor 11 monitors the temperature inside the fly ash storage silo 1 in real time. The resistance heating device 12 heats the fly ash storage silo 1 by controlling the current to the resistor, causing it to release heat. Feedback control is performed based on the real-time temperature detected by the temperature sensor 11 to maintain a constant temperature of 900℃ inside the fly ash storage silo 1.

[0024] The conveying device 2 includes an inlet header 21, a tubular chain conveyor 22, and an outlet header 23. The inlet header 21 is fixedly installed at the bottom of the fly ash storage silo 1, and the outlet header 23 is fixedly installed at the top of the fly ash heat exchange silo 3. The inlet header 21 and the outlet header 23 are connected by the tubular chain conveyor 22. A waste gas collection device 4 is installed on the top of the outlet header 23. Fly ash enters from the inlet header 21 and is conveyed to the outlet header 23 by the tubular chain conveyor 22. The body material of the inlet header 21, the tubular chain conveyor 22, and the outlet header 23 is stainless steel, preferably 0Cr25Ni20, and the rotating bearing is graphite, which meets the high-temperature conveying requirements of fly ash. During the transfer process, a small amount of pollutants such as dioxins decomposed by high temperature in the fly ash are centrally treated by the waste gas collection device 4.

[0025] The fly ash heat exchange chamber 3 is equipped with a heat exchanger 31. A second gate 32 is located at the top of the fly ash heat exchange chamber 3. A discharge port 33 is located at the bottom of the fly ash heat exchange chamber 3. The temperature from the fly ash vaporizes the brine in the heat exchanger 31, turning it into steam. This steam can be used as a heat source for other projects or to drive a steam turbine for power generation, thus achieving heat energy recovery. A valve is installed at the discharge port 33, which opens when discharging and closes when not discharging.

[0026] Working principle: Fly ash enters the fly ash storage bin 1 through the feed inlet 13. The resistance heating device 12, together with the temperature sensor 11, heats the fly ash, causing it to decompose at a high temperature. Then, the fly ash is conveyed from the fly ash storage bin 1 to the fly ash heat exchange bin 3 through the conveying device 2. In the fly ash heat exchange bin 3, the heat is recovered through the heat exchanger 31 to reduce heat loss.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
