[0001] The present invention relates to the technical field of garbage treatment, and particularly relates to a monitoring and feedback system for garbage incineration flue gas and fly ash. Background Art

[0002] Garbage incineration can maximize the reduction, harmlessness, and resource utilization of garbage. However, incineration inevitably brings secondary pollution. The flue gas generated by garbage incineration contains a large amount of substances harmful to the environment, such as acidic gases, nitrogen oxides, dust, dioxins, heavy metals, etc. Therefore, it is very necessary to thoroughly purify the flue gas generated by garbage incineration before discharging it into the atmosphere to minimize its impact on the surrounding environment.

[0003] Currently, the purification treatment of garbage incineration flue gas in China basically adopts a combined flue gas treatment process, including semi-dry desulfurization, activated carbon adsorption of dioxins, and bag filter dust removal. The treatment effect of garbage incineration flue gas is relatively good. However, due to the different incineration amounts of garbage, the composition of garbage, and incineration conditions, the composition of the flue gas generated after garbage incineration is different. Therefore, the flue gas purification effect is often not good, and it cannot be adjusted in time, resulting in environmental pollution. Summary of the Invention

[0039] Advantages of the present invention:

[0040] A monitoring and feedback system for waste incineration flue gas and fly ash of the present invention atomizes and sprays ammonia water in a denitration tower to make it react with NOx in the flue gas, convert NOx into N2. The denitrified flue gas then enters an acid removal tower and contacts with the atomized lime slurry sprayed in the acid removal tower, so that HCl and SO2 in the flue gas are absorbed by the lime slurry, and then CaSO4, CaSO3, and CaCl2 powders are generated. The flue gas after passing through the acid removal tower enters a purification tower, and activated carbon is sprayed in the purification tower. The activated carbon contacts with the flue gas, and then the activated carbon adsorbs dioxins and heavy metals in the flue gas. The purified flue gas enters a bag filter to remove fly ash in the flue gas; the monitoring and feedback system for waste incineration flue gas and fly ash can denitrify, remove acid, and separate fly ash from the waste incineration flue gas, so as to fully purify the flue gas, make it meet the emission standards, and protect the environment;

[0041] Through the monitoring and feedback platform, the flue gas treatment equipment can be monitored. First, the parameter monitoring module is used to collect the flue gas pollution coefficient of the flue gas treatment equipment, which is used to measure the pollution degree of the flue gas discharged from the waste incinerator, denitration tower, deacidification tower, purification tower and dust collector respectively. The larger the flue gas pollution coefficient, the more serious the pollution. The processor obtains the monitoring and feedback coefficient of the dust collector. When the monitoring and feedback coefficient exceeds the preset monitoring and feedback threshold, it means that the purification treatment effect of the tail gas discharged from the dust collector is not good, and supervision, feedback and adjustment are needed. The processor judges through the judgment angle. If the judgment angle is less than the preset judgment threshold, it means that the adjustment effect is not good, and continuous adjustment is still needed until the judgment angle is not less than the preset judgment threshold. The parameter analysis module is used to obtain the deviation value according to the broken line angle. The deviation value is used to measure the treatment effect of the waste incinerator, denitration tower, deacidification tower, purification tower and dust collector on the flue gas respectively. The larger the deviation value, the better the treatment effect of the corresponding flue gas treatment equipment on the flue gas. The flue gas treatment equipment with the smallest deviation value is marked as the selected equipment, and the selected equipment is adjusted through the parameter adjustment module. First, the angle of the material spraying atomization angle is adjusted to the preset angle, and then the relative speed of the material and the flue gas is adjusted by adjusting the material speed value, and the material diameter value is adjusted to increase the contact area between the material and the flue gas, thereby improving the treatment effect of the material on the flue gas. The selected equipment is adjusted in turn according to the deviation value arrangement order until the discharged flue gas meets the standards; The monitoring and feedback system can fully purify the flue gas by using the flue gas treatment equipment, can monitor the flue gas treatment equipment in real time through the monitoring and feedback platform, and adjust it, which is suitable for treating the flue gas generated by waste incineration in different situations, and can achieve the best effect each time.

The monitoring and feedback system for waste incineration flue gas and fly ash according to claim 1, wherein The working process of the parameter analysis module to obtain the selected device is as follows: After receiving the first analysis instruction, obtain the data packets in the historical data, merge all the broken line angles, and mark the broken line angle with the most occurrences as the standard broken line angle; Analyze the broken line angle and the standard broken line angle to obtain the deviation values, including the furnace nitrate deviation value, nitric acid deviation value, acid purification deviation value, and dust purification deviation value; Compare the furnace nitrate deviation value, nitric acid deviation value, acid purification deviation value, and dust purification deviation value with each other, then sort them in ascending order, mark the deviation value at the end as the standard deviation value, mark the broken line corresponding to the deviation value at the beginning as the selected broken line, mark the remaining broken lines as the preselected broken lines, mark the independent variable at the end point of the selected broken line as the selected device, and mark the independent variable at the end point of the preselected broken line as the preselected device; Send the selected device to the parameter adjustment module; After receiving the Nth analysis instruction, mark the preselected device at the beginning as the selected device; Send the selected device to the parameter adjustment module.

5. The monitoring and feedback system for waste incineration flue gas and fly ash according to claim 1, characterized in that, The working process of the parameter adjustment module to adjust the selected device is as follows: Collect the flue gas rate entering the selected device, the material spraying rate, and the material spraying particle size, and mark them as the flue gas speed value, the material speed value, and the particle size value respectively; Obtain the material spraying atomization angle, keep the flue gas speed value, the material speed value, and the particle size value unchanged, establish a coordinate graph with the material spraying atomization angle as the independent variable and the smoke pollution coefficient as the dependent variable, draw a curve graph, and obtain the material spraying atomization angle corresponding to the valley value of the curve graph and mark it as the preset angle; Adjust the angle of the material spraying atomization angle to the preset angle; After the angle adjustment is completed, analyze the flue gas speed value, the material speed value, and the particle size value to obtain the adjustment value; Adjust the adjustment value according to the preset adjustment rate. When the deviation value ≥ the standard deviation value, generate a comparison instruction and send the comparison instruction to the processor.
