Description

Technical Field

[0001] The present invention belongs to the technical field of solid fuel evaluation, and specifically relates to an environmental protection evaluation system for solid fuels based on big data. Background Art

[0002] Solid fuels refer to fuels that exist in a solid state and can burn to release energy. They come in a wide variety and have different characteristics, and are widely used in industries, power generation, and civilian applications. Among them, solid fuels will release a large amount of harmful substances such as nitrogen oxides, ammonia, and carbon dioxide when burning. These harmful substances will cause damage to human health and the environment after being discharged into the atmosphere. Therefore, before putting solid fuels into use, it is necessary to conduct sampling detection and evaluation on solid fuels to determine whether the solid fuels to be put into use meet the combustion standards and evaluate their impact on the environment. During the evaluation, when the traditional evaluation system conducts environmental protection evaluation on solid fuels, it usually adopts the method of detecting emissions. When the emissions generated after burning each unit amount of solid fuel are excessive, it is determined that the solid fuel is unqualified. However, due to the different combustion degrees of each batch of solid fuels, there will be significant differences in the harmful substances discharged with the consumption of the fuel. The traditional detection method is not accurate enough and is difficult to provide a more accurate evaluation method. Summary of the Invention

Obviously, the drawings in the following description are only some embodiments of the present invention.

[0014] The following will clearly and completely describe the technical solutions of the present invention in combination with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0015] Please refer to Figures 1 to 2 , the embodiments of the present invention provide an environmental protection evaluation system for solid fuels based on big data, including: an information collection module: before the experiment, a certain amount of solid fuel is placed at the test point, for example, weighed on a weighing scale, and the material information before the experimental combustion is collected. Then the solid fuel is ignited to conduct a combustion experiment on the solid fuel. After the solid fuel burns, the solid residue in the container used for combustion is taken out, and the weight of the residue collected from the solid fuel is collected; After measuring the weight of the residue, the residue detection module is used to detect the residue, so as to analyze the harmful substances in the residue, analyze and list the components in the residue, and calculate the proportion of each pollutant in the residue at the same time. The calculated data is plotted as a bar chart for easy viewing; During the combustion process, the generated flue gas is collected to judge the total amount of the flue gas. The flue gas detection module is used to detect the flue gas after combustion, analyze the components in the flue gas, and calculate the proportion of each pollutant in the flue gas. The calculated data is plotted as a bar chart for easy viewing; After collecting and detecting the components in the residue and the flue gas, the data is sent to the screening module. The screening module compares the collected data with the data in the harmful substance database one by one, screens out the harmful substances in the residue and the flue gas, and transmits the screened harmful substance information to the primary evaluation module, so that the primary evaluation module and the secondary evaluation module only need to detect and analyze the components of some harmful substances; After the primary evaluation module receives the harmful substance information screened by the screening module, it evaluates this harmful substance information one by one and compares it with the emission standard values one by one, so as to evaluate whether the amount of each harmful substance exceeds the allowable standard value; When all the harmful substances detected by the primary detection module are qualified, the evaluation values of each harmful substance are sent to the secondary evaluation module. Through the secondary evaluation module, a comprehensive evaluation is carried out on the pollutant information emitted by the solid fuel used in the experiment, and it is judged whether the total amount of harmful substances emitted by the solid fuel used in the experiment exceeds the standard.

[0016] Specifically, in this embodiment, the information collection module collects the input weight of the solid fuel in the laboratory, detects the weight of the remaining residue, and calculates the amount of fuel burned through the following formula: ; The combustion rate of the batch of solid fuel used in this experiment is deduced through the amount of fuel burned. Specifically, the combustion rate of this batch of solid fuel is calculated through the following formula: ; Among them, P is the combustion rate of this batch of fuel, G is the amount of fuel burned, G 总 is the total amount of combustibles input, G 剩 is the weight of the remaining residue.

[0017] In one embodiment of the present invention, the primary evaluation module judges whether the residue after burning of this batch of solid fuel is excessive according to the combustion rate of this batch of solid fuel. When the combustion rate is too low, it means that this batch of solid fuel is not suitable for burning. When encountering solid fuel that is not suitable for burning, there is no need to conduct further evaluation: Among them, when P≥P 标 -N, it means that the combustion rate of this batch of solid fuel is higher than that of the solid fuel that meets the standard. At this time, the pollutant information of this batch of solid fuel can be re-evaluated through the primary evaluation module; when the combustion rate is higher, the remaining solid residue will be relatively less, and more flue gas will be generated. On the contrary, when the combustion rate is lower, the remaining solid residue will be relatively more, and less flue gas will be generated.

[0018] When P<P 标 -N, it means that the combustion rate of this batch of solid fuel is lower than that of the solid fuel that meets the standard; Among them, P 标 is the combustion rate of the solid fuel that meets the standard, and N is the allowable combustion rate error when the solid fuel that meets the standard burns; the combustion rate of the solid fuel to be evaluated within the standard combustion rate error range belongs to the combustibles that meet the standard.

[0019] In one embodiment of the present invention, the residue detection module calculates the proportion of various pollutants through the following formula: ; where V 固 is the proportion of one of the pollutants remaining in the solid residue, and G 固污 is the amount of the corresponding pollutant contained in the solid residue.

[0020] The flue gas detection module calculates the proportion of each pollutant in the flue gas through the following formula: ; where V 烟 is the proportion of one of the pollutants remaining in the flue gas, V 烟污 is the amount of the pollutant in the flue gas, and V 总 is the total amount of the flue gas.

[0021] In one embodiment of the present invention, the data detected by the residue detection module and the flue gas detection module are sent to the primary evaluation module after screening. The primary evaluation module compares each item of data with the solid fuel used as the reference standard. The primary evaluation module evaluates the detected pollutants through the following formula to obtain the evaluation value of the pollution degree of the pollutants in the corresponding flue gas to the atmosphere: ; where Q1 is the evaluation value of the pollution degree of one of the pollutants in the flue gas to the atmosphere, Q is the evaluation value of the pollution degree of the evaluated pollutant per cubic meter to the atmosphere, and V 烟标 is the proportion of the corresponding pollutant per cubic meter of the combustible during combustion; When the evaluation value Q1 of one of the pollutants is greater than Q + M, the primary evaluation module marks this batch of solid fuel as unqualified fuel. When the detection result is unqualified, the secondary evaluation is abandoned; When the evaluation values Q1 of all the pollutants detected by the primary detection module are less than or equal to Q + M, the primary evaluation module marks this batch of solid fuel as qualified fuel and transmits the data of each pollutant of this batch of fuel to the secondary evaluation module for secondary evaluation. The secondary evaluation module conducts a comprehensive evaluation of this batch of solid fuel to judge the comprehensive impact of the pollutants generated during the combustion of this batch of solid fuel on the environment; where Q is the evaluation value within the allowable range of the pollutants corresponding to the input amount of solid fuel, and M is the allowable error value.

[0022] In this way, the screening by the primary module can effectively and quickly evaluate the solid fuel. When one of the pollutants exceeds the standard, the secondary evaluation is not required, improving the screening efficiency.

[0023] In one embodiment of the present invention, the primary evaluation module evaluates the pollutants in the detected residues through the following formula to obtain the evaluation value of the pollution degree of the pollutants in the corresponding residues to the environment: ; where U1 is the evaluation value of the pollution degree of one of the pollutants in the residues to the environment, U is the evaluation value of the pollution degree of the pollutants in the residues evaluated per cubic meter to the environment, and V 固标 is the proportion of the pollutants in the residues corresponding to the combustion of the standard-compliant combustibles per cubic meter; When the evaluation value U1 of one of the pollutants in the residues is greater than U + J, the primary evaluation module marks this batch of solid fuels as unqualified fuels. At this time, the pollutant data of this batch of solid fuels will no longer be sent to the secondary evaluation module; When the evaluation values U1 of all pollutants are less than or equal to U + J, the primary evaluation module marks this batch of solid fuels as qualified fuels and transmits the pollutant data of this batch of fuels to the secondary evaluation module; where U is the evaluation value within the allowable range of the pollutants in the residues corresponding to the input amount of solid fuels, and J is the allowable error value. When the evaluation value of the pollution degree of the pollutants in the residues detected by the primary detection module belongs to the allowable range and the evaluation value of the pollution degree of the pollutants in the flue gas to the atmosphere belongs to the allowable range, the data of this batch of solid fuels is transmitted to the secondary evaluation module, and the secondary evaluation module conducts a secondary evaluation on this batch of solid fuels.

[0024] In one embodiment of the present invention, the secondary evaluation module evaluates the comprehensive evaluation value of the environmental pollution of this batch of solid fuels through the following formula: ; where Q 综 is the comprehensive evaluation value of the environmental pollution of this batch of solid fuels; When , it means that the total amount of harmful substances generated during the combustion of this batch of solid fuels is too large and is not suitable for combustion, and this batch of solid fuels is marked as not meeting the combustion standard; When , it means that the total amount of harmful substances generated during the combustion of this batch of solid fuels is within the standard range. At this time, this batch of fuels is marked as qualified products, thus completing the evaluation of this batch of solid fuels. where Q 标 is the comprehensive evaluation value of the standard-compliant fuels per cubic meter, and M1 is the allowable error range of the comprehensive evaluation value.

[0025] Through the comprehensive assessment of the pollutants of solid fuel by the secondary assessment module, the comprehensive pollution degree of solid fuel can be effectively judged. When the total amount of harmful substances generated exceeds the standard, it means that this batch of solid fuel is unqualified and not suitable for combustion, and the impact on the environment is too large. Only when the comprehensive assessment value is within the standard range can it be put into use.

[0026] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
