It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
The embodiment of the invention provides a fly ash innocent treatment method which is applied to a fly ash innocent treatment device. The steps involved in the method are described in detail below in conjunction with fig. 1.
Step 101: parameter information of the gas in the cavity is acquired.
Wherein the parameter information includes a first temperature of the gas and a gas concentration.
In the embodiment of the invention, the waste gas and the exhaust gas generated by the industrial combustion of the gas in the cavity contain nitrogen oxides, sulfur oxides, various hydrocarbons, alcohols, aldehydes, acids, ketones, amines and particle pollutants. The fly ash is part of ash along with the waste gas, the fly ash is dangerous waste generated by a garbage incineration plant, and the fly ash is formed by cooling pulverized coal after entering a hearth with the temperature of 1300-1500 ℃ and being subjected to heat absorption of a hot surface under the suspension combustion condition; the fly ash contains not only unburned coal particles but also a large amount of oxides of silicon, iron, aluminum, calcium, magnesium, sodium, potassium and sulfur and various trace elements.
The exhaust gas and fly ash in the chamber are illustratively introduced into the chamber through the gas inlet, and have a certain temperature because fly ash is newly generated in a high-temperature environment. The position of the air inlet is provided with a sensor, and the concentration of fly ash and the first temperature of the fly ash in the air inlet in unit time are detected based on the sensor.
Step 102: a target speed matching the concentration is determined based on the parameter information.
In the embodiment of the present invention, step 102 of determining the target speed matched with the concentration based on the parameter information includes:
in the embodiment of the invention, the target speed is used for representing the speed of the fly ash driven by the conveying belt in the cavity.
Step 1021, determining a target speed matching the gas concentration based on the gas concentration.
In the embodiment of the present invention, in step 1021, based on the gas concentration, the determination of the target speed matched with the gas concentration may be achieved by the following two methods:
mode one: determining a first speed of the conveyor belt at the current moment according to the gas concentration; if the first temperature is smaller than the preset temperature, increasing the power of the microwave source and determining the second speed of the transmission belt; correspondingly, the innocent treatment of the fly ash based on the target speed comprises the following steps: and performing innocent treatment on the fly ash based on the second speed.
In the embodiment of the invention, the first temperature refers to the temperature of the fly ash entering through the air inlet, and the preset temperature is the standard temperature of the fly ash allowed by the cavity. The controller determines the running speed of the conveyor belt according to the relation between the first temperature and the preset temperature, and the maximum treatment can be achieved for the fly ash.
If the first temperature is greater than or equal to the preset temperature, reducing the power of the microwave source and determining the third speed of the transmission belt; correspondingly, the innocent treatment of the fly ash based on the target speed comprises the following steps: and carrying out innocent treatment on the fly ash based on the third speed.
In the embodiment of the invention, if the controller determines that the temperature of the fly ash is greater than or equal to the preset temperature according to the received information, the third speed is smaller than the second speed, and the conveyor belt is controlled to run at the third speed, so that the effect of reducing energy consumption while efficiently treating the fly ash and the waste gas is achieved.
Step 103: and carrying out innocent treatment on the fly ash based on the target speed.
