Description

Technical Field

[0001] This invention relates to the field of municipal solid waste incineration technology, specifically to a dioxin emission control system for municipal solid waste incineration facilities based on a forest algorithm. Background Technology

[0002] Currently, China's waste-to-energy industry is experiencing rapid development. However, with the strengthening of environmental protection departments' supervision of flue gas emissions, the emission of dioxins from waste incineration plants has become a major environmental concern. Because dioxins pose a significant threat to the environment and human health, it is essential to control their emissions from municipal solid waste incineration facilities.

[0003] Currently, the concentration of dioxins emitted by waste incineration plants is very low, and can only be detected through offline laboratory sampling and analysis, not online monitoring. This means that environmental protection departments and operating companies cannot monitor operating waste incineration systems in real time, and can only rely on manual experience and remedial measures after exceeding standards to prevent dioxin exceedances. In this situation, once standards are exceeded, environmental penalties will be imposed, causing serious economic losses and adverse social impacts.

[0004] Therefore, if online monitoring and timely control can be implemented through forest algorithms, the chances of dioxin emissions exceeding standards can be significantly reduced, thus avoiding serious consequences such as environmental penalties for exceeding emission limits. However, there has been no substantial progress in the waste incineration industry, and effective online dioxin control technologies are lacking. Therefore, it is necessary to strengthen relevant technology research and development, explore effective methods and means for online monitoring and early warning of dioxins, and provide technical support and guarantees for the sustainable development of the waste incineration industry.

[0028] Preferably, the purification assessment coefficients corresponding to municipal solid waste incineration facilities are analyzed, and the analysis process is as follows:

[0029] The volume of activated carbon is obtained from the image corresponding to the activated carbon, and monitoring points are set up in the area where the activated carbon is placed. The thickness of the activated carbon at each monitoring point is then obtained from the activated carbon image, denoted as V and H. i Where i represents the number corresponding to each monitoring point, i = 1, 2, ..., n;

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Examples of embodiments of the present invention Figure 1 As shown, the dioxin emission control system for municipal solid waste incineration facilities based on the forest algorithm includes: an emission parameter acquisition module, an emission parameter analysis module, a combustion and purification parameter acquisition module, a combustion parameter analysis module, an activated carbon image analysis module, an adjustment parameter analysis module, and a display terminal.

The adjustment parameter analysis module is connected to the display terminal.

[0047] Emission parameter acquisition module: used to collect the concentration of dioxin emissions from municipal solid waste incineration facilities.

[0048] In one specific embodiment, the concentration of dioxin emissions from a municipal solid waste incineration facility is collected, and the collection process is as follows:

[0049] A1. The entire production line of a municipal solid waste incineration facility, from feeding to the chimney, is used as the sampling area.

[0050] A2. Install several collection devices in the collection area of ​​the municipal solid waste incineration facility, and then randomly collect the concentration of dioxin emissions at several collection points during multiple time periods during the operation of the municipal solid waste incineration facility;

[0051] It should be noted that the collection device is a dioxin sampler.

[0052] A3. The average value of dioxin emissions from municipal solid waste incineration facilities is obtained by averaging.

[0053] Emission parameter analysis module: This module is used to obtain the average dioxin concentration of municipal solid waste incineration facilities based on the concentration of dioxins emitted from these facilities, and to determine whether the average dioxin concentration in the facilities is within acceptable limits.

[0054] In one specific embodiment, the determination of whether the average value of dioxins in a municipal solid waste incineration facility is within acceptable limits is carried out as follows:

[0055] The average dioxin level of the municipal solid waste incineration facility is compared with the set threshold for the average dioxin level of the municipal solid waste incineration facility. If the average dioxin level of the municipal solid waste incineration facility is greater than the threshold for the average dioxin level of the municipal solid waste incineration facility, the average dioxin level of the municipal solid waste incineration facility is deemed unqualified; otherwise, the average dioxin level of the municipal solid waste incineration facility is deemed qualified.

[0056] Combustion and purification parameter acquisition module: When the average value of dioxins in the municipal solid waste incineration facility is not up to standard, it is used to collect the corresponding combustion temperature, combustion wind speed and combustion time in the municipal solid waste incineration facility, as well as the corresponding activated carbon image in the municipal solid waste incineration facility.

[0057] In one specific embodiment, the combustion temperature, combustion wind speed, and combustion duration of the municipal solid waste incineration facility, as well as the corresponding activated carbon image of the facility, are collected. The collection process is as follows:

[0058] S1. The combustion temperature in the municipal solid waste incineration facility is collected by an infrared temperature sensor installed at a preset distance from the facility.

[0059] S2. The combustion wind speed in the municipal solid waste incineration facility is collected by a wind speed sensor installed at the air inlet of the facility.

[0060] It should be noted that the wind speed at the inlet of the municipal solid waste incineration facility is taken as the combustion wind speed.

[0061] S3. The combustion time in the municipal solid waste incineration facility is collected by using a timer in the facility.

[0062] S4. Install a camera above the activated carbon placement area of ​​the municipal solid waste incineration facility, and then use the camera to collect images of the activated carbon in the placement area.

[0063] Combustion parameter analysis module: This module analyzes the combustion evaluation coefficients of municipal solid waste incineration facilities based on the combustion temperature, combustion wind speed, and combustion duration, thereby determining whether the combustion status of the municipal solid waste incineration facilities is qualified.

[0064] In a specific embodiment, the combustion assessment coefficients corresponding to the municipal solid waste incineration facility are analyzed, and the analysis process is as follows:

[0065] Substitute the corresponding combustion temperature, combustion velocity, and combustion duration from the municipal solid waste incineration facility into the calculation formula. In the process, the combustion evaluation coefficient δ corresponding to the municipal solid waste incineration facility is obtained, where t, v, and w represent the combustion temperature, combustion wind speed, and combustion duration corresponding to the municipal solid waste incineration facility, respectively; t′, v′, and w′ are the reference combustion temperature, reference combustion wind speed, and reference combustion duration corresponding to the municipal solid waste incineration facility, respectively; and ε1, ε2, and ε3 are the weighting factors corresponding to the combustion temperature, combustion wind speed, and combustion duration corresponding to the municipal solid waste incineration facility, respectively.

[0066] It should be noted that combustion temperature refers to the temperature inside the combustion chamber during the incineration of municipal solid waste. Higher combustion temperatures result in a faster combustion reaction rate, increased combustion efficiency, and reduced dioxin formation. Faster combustion airflow also improves combustion efficiency and reduces dioxin formation. Combustion duration refers to the time municipal solid waste remains in the combustion chamber. Longer combustion duration leads to more complete combustion, increased efficiency, and reduced dioxin formation.

[0067] In another specific embodiment, the process for determining whether the combustion state in the municipal solid waste incineration facility is qualified is as follows:

[0068] The combustion assessment coefficient corresponding to the municipal solid waste incineration facility is compared with the set combustion assessment coefficient corresponding to the municipal solid waste incineration facility. If the combustion assessment coefficient corresponding to the municipal solid waste incineration facility is less than the set combustion assessment coefficient corresponding to the municipal solid waste incineration facility, the combustion state of the municipal solid waste incineration facility is deemed unqualified. Conversely, if the coefficient is greater than the set coefficient, the combustion state of the municipal solid waste incineration facility is deemed qualified.

[0069] Activated carbon image analysis module: This module analyzes the corresponding purification evaluation coefficients in municipal solid waste incineration facilities based on the activated carbon images of the corresponding purifiers, thereby determining whether the purification effect of the municipal solid waste incineration facilities is up to standard.

[0070] In one specific embodiment, the purification assessment coefficients corresponding to the municipal solid waste incineration facility are analyzed. The analysis process is as follows:

[0071] The volume of activated carbon is obtained from the image corresponding to the activated carbon, and monitoring points are set up in the area where the activated carbon is placed. The thickness of the activated carbon at each monitoring point is then obtained from the activated carbon image, denoted as V and H. i Where i represents the number corresponding to each monitoring point, i = 1, 2, ..., n;

[0072] Through calculation formula In the process, the corresponding purification evaluation coefficient β for municipal solid waste incineration facilities is obtained, where V′ and H i' represents the standard volume and standard thickness of the set municipal solid waste incineration facility, respectively, and η1 and η2 are the weighting factors of the corresponding volume and thickness of the set municipal solid waste incineration facility.

[0073] It should be noted that the adsorption effect of activated carbon is affected by its total volume and distribution thickness. When the total volume or distribution thickness of activated carbon does not meet the standards, the adsorption effect will also decrease, resulting in excessively high dioxin emission concentrations.

[0074] In another specific embodiment, the determination of whether the corresponding purification effect in the municipal solid waste incineration facility is qualified is carried out as follows:

[0075] The purification evaluation coefficient corresponding to the municipal solid waste incineration facility is compared with the set purification evaluation coefficient corresponding to the municipal solid waste incineration facility. If the purification evaluation coefficient corresponding to the municipal solid waste incineration facility is less than the set purification evaluation coefficient corresponding to the municipal solid waste incineration facility, the purification effect of the municipal solid waste incineration facility is deemed unqualified. Conversely, if the coefficient is greater than the set coefficient, the purification effect of the municipal solid waste incineration facility is deemed qualified.

The corresponding combustion temperature difference in the municipal solid waste incineration facility shall then be used as the combustion temperature adjustment value.

[0079] K2. If the combustion state in the municipal solid waste incineration facility is not up to standard, the corresponding reference combustion wind speed in the municipal solid waste incineration facility shall be subtracted from the corresponding combustion wind speed in the municipal solid waste incineration facility to obtain the corresponding combustion wind speed difference in the municipal solid waste incineration facility, and then the corresponding combustion wind speed difference in the municipal solid waste incineration facility shall be used as the combustion wind speed adjustment value.

[0080] K3. If the combustion state in the municipal solid waste incineration facility is not up to standard, the corresponding reference combustion time in the municipal solid waste incineration facility shall be subtracted from the corresponding combustion time in the municipal solid waste incineration facility to obtain the corresponding combustion time difference in the municipal solid waste incineration facility, and then the corresponding combustion time difference in the municipal solid waste incineration facility shall be used as the combustion time adjustment value.

[0081] K4. If the purification effect in the municipal solid waste incineration facility is not up to standard, the standard volume of the activated carbon in the municipal solid waste incineration facility shall be subtracted from the corresponding volume in the municipal solid waste incineration facility to obtain the corresponding volume difference in the municipal solid waste incineration facility. The corresponding volume difference in the municipal solid waste incineration facility shall then be used as the activated carbon volume adjustment value.

If the purification effect in the municipal solid waste incineration facility is not up to standard, the standard thickness of the activated carbon in the municipal solid waste incineration facility shall be subtracted from the corresponding thickness in the municipal solid waste incineration facility to obtain the corresponding thickness difference in the municipal solid waste incineration facility. The corresponding thickness difference in the municipal solid waste incineration facility shall then be used as the activated carbon thickness adjustment value.

[0083] The display terminal is used to display adjustment information corresponding to municipal solid waste incineration facilities.

[0084] The adjustment values ​​for combustion temperature, combustion wind speed, combustion duration, activated carbon volume, and activated carbon thickness are used as the corresponding adjustment information for municipal solid waste incineration facilities.

[0085] This invention analyzes the adjustment information corresponding to municipal solid waste incineration facilities, thereby enabling rapid transmission of the adjustment information to a display terminal. This effectively safeguards the online dioxin control technology and provides technical support for the sustainable development of the waste incineration industry.

[0086] The beneficial effect of this invention lies in providing a dioxin emission control system for municipal solid waste incineration facilities based on the forest algorithm. This system monitors the concentration of dioxins emitted from the incineration facility online using the forest algorithm, enabling real-time monitoring of the operating incineration system. Analysis is then performed based on the corresponding combustion assessment coefficient and purification assessment coefficient to determine whether the combustion status of the incineration facility is up to standard. This allows for timely adjustments to the dioxin emission concentration, significantly reducing the chance of exceeding dioxin emission standards and avoiding serious consequences such as environmental penalties for exceeding emission limits.

The dioxin emission control system for municipal solid waste incineration facilities based on the forest algorithm as described in claim 1, characterized in that, The method for analyzing adjustment information corresponding to municipal solid waste incineration facilities when the combustion status or purification effect is unqualified is as follows: K1. If the combustion state in the municipal solid waste incineration facility is not up to standard, the corresponding reference combustion temperature in the municipal solid waste incineration facility shall be subtracted from the corresponding combustion temperature in the municipal solid waste incineration facility to obtain the corresponding combustion temperature difference in the municipal solid waste incineration facility. The corresponding combustion temperature difference in the municipal solid waste incineration facility shall then be used as the combustion temperature adjustment value. K2. If the combustion state in the municipal solid waste incineration facility is not up to standard, the corresponding reference combustion wind speed in the municipal solid waste incineration facility shall be subtracted from the corresponding combustion wind speed in the municipal solid waste incineration facility to obtain the corresponding combustion wind speed difference in the municipal solid waste incineration facility, and then the corresponding combustion wind speed difference in the municipal solid waste incineration facility shall be used as the combustion wind speed adjustment value. K3. If the combustion state in the municipal solid waste incineration facility is not up to standard, the corresponding reference combustion time in the municipal solid waste incineration facility shall be subtracted from the corresponding combustion time in the municipal solid waste incineration facility to obtain the corresponding combustion time difference in the municipal solid waste incineration facility, and then the corresponding combustion time difference in the municipal solid waste incineration facility shall be used as the combustion time adjustment value. K4. If the purification effect in the municipal solid waste incineration facility is not up to standard, the standard volume of the activated carbon in the municipal solid waste incineration facility shall be subtracted from the corresponding volume in the municipal solid waste incineration facility to obtain the corresponding volume difference in the municipal solid waste incineration facility. The corresponding volume difference in the municipal solid waste incineration facility shall then be used as the activated carbon volume adjustment value. K5. If the purification effect in the municipal solid waste incineration facility is not up to standard, the standard thickness of the activated carbon in the municipal solid waste incineration facility shall be subtracted from the corresponding thickness in the municipal solid waste incineration facility to obtain the corresponding thickness difference in the municipal solid waste incineration facility. The corresponding thickness difference in the municipal solid waste incineration facility shall then be used as the activated carbon thickness adjustment value. The adjustment values ​​for combustion temperature, combustion wind speed, combustion duration, activated carbon volume, and activated carbon thickness are used as the corresponding adjustment information for municipal solid waste incineration facilities.
