Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a method for dynamic matching of hazardous waste. Background Technology

[0002] Hazardous waste is first mixed in the feed pit before being put into the furnace for incineration.

[0003] Currently, existing technology discloses a method for blending hazardous waste, which involves manually blending the initial hazardous waste to be blended with the existing hazardous waste based on experience. However, the compatibility of the wastes after each blending is unstable, thereby reducing the stability of the wastes during the incineration process. Summary of the Invention

[0004] The purpose of this invention is to provide a dynamic compatibility method for hazardous waste, which aims to solve the problem of unstable compatibility indicators of wastes in existing hazardous waste compatibility methods.

[0005] To achieve the above objectives, the present invention provides a method for dynamic compatibility of hazardous waste, comprising the following steps:

[0006] S1 breaks down all the waste in the warehouse into batches on pallets, resulting in multiple palletized wastes;

[0007] S2 selects any batch of the pallet waste as the starting waste for matching, compares each element of the starting waste with the matching target, and obtains the first element with the largest difference.

[0008] S3 polls all the pallet wastes and calculates the average value of the element with the largest first difference after each polled pallet waste is mixed with the initial compatible waste according to the index;

[0009] S4 adds the pallet waste corresponding to the average value closest to the target value and the initial compatible waste to the compatibility scheme to obtain the first scheme;

[0010] S5 compares each element of the first scheme with the matching target to obtain the second element with the largest difference, and repeats steps S3 to S4 to obtain the second scheme.

[0011] S6 compares the second scheme with the target weight and target range to obtain the comparison results, and generates the final scheme based on the comparison results.

[0012] The step of comparing the second solution with the target weight and target range to obtain a comparison result, and generating a final solution based on the comparison result, includes:

[0013] The second scheme is compared with the target weight and target range. If the second scheme reaches the target weight and target range, the matching is stopped and the final scheme is obtained. If the second scheme does not reach the target weight and target range, each element of the second scheme is calculated and compared with the matching target to obtain the third element with the largest difference. Steps S3 to S4 are repeated to obtain the third scheme for comparison again until the scheme reaches the target weight and the final scheme is obtained.

[0014] Each of these elements includes P, N, S, Cl, F, Br, C, H, I, Pb, and Zn.

[0015] The indicators include calorific value, the content of each element, and its weight.

[0016] The step of polling all the palletized waste and calculating the average value of the element with the largest first difference after mixing each polled palletized waste with the initial compatible waste, according to the indicators, includes:

[0017] All the said pallet wastes are polled, and quantitative mixing calculations are performed based on calorific value, content and weight of each element. The average value of the first element with the largest difference is calculated after each polled pallet waste is mixed with the initial compatible waste.

[0018] This invention discloses a dynamic compatibility method for hazardous waste. The method involves breaking down all waste in a warehouse into batches, palletized units, to obtain multiple palletized wastes. Any batch of palletized waste is selected as the initial compatibility waste. Each element of the initial compatibility waste is compared with a compatibility target to obtain a first element with the largest discrepancy. All palletized wastes are polled, and the average value of the first element with the largest discrepancy after mixing each polled palletized waste with the initial compatibility waste is calculated based on indicators. The palletized waste corresponding to the average value closest to the target value is added to the initial compatibility waste to obtain a first scheme. Each element of the first scheme is compared with the compatibility target to obtain a second element with the largest discrepancy, and then polled to obtain a second scheme. The second scheme is compared with the target weight and target range to obtain a comparison result, and a final scheme is generated based on the comparison result. By analyzing and identifying the properties of hazardous wastes, the compatibility of the compatibility wastes is ensured, solving the problem of unstable compatibility indicators in existing hazardous waste compatibility methods.

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] Please see Figures 1 to 3 This invention provides a method for dynamic compatibility of hazardous waste, comprising the following steps:

[0025] S1 breaks down all the waste in the warehouse into batches on pallets, resulting in multiple palletized wastes;

[0026] The specific method is as follows:

[0027] S11 divides all the waste in the warehouse into batches, resulting in multiple batches of waste;

[0028] Specifically, based on the transfer records of each waste, all waste in the warehouse is divided into batches, resulting in multiple batches of waste.

[0029] S12 divides each batch of waste into multiple pallets, using pallets as the unit.

[0030] S2 selects any batch of the pallet waste as the starting waste for matching, compares each element of the starting waste with the matching target, and obtains the first element with the largest difference.

[0031] Specifically, each element includes P, N, S, Cl, F, Br, C, H, I, Pb, and Zn.

[0032] S3 polls all the pallet wastes and calculates the average value of the element with the largest first difference after each polled pallet waste is mixed with the initial compatible waste according to the index;

[0033] Specifically, the indicators include calorific value, the content of each element, and its weight. All the palletized waste is polled, and a quantitative mixing calculation is performed based on the calorific value, the content of each element, and its weight. The average value of the element with the largest first difference after mixing each polled palletized waste with the initial compatible waste is calculated.

[0034] S4 adds the pallet waste corresponding to the average value closest to the target value and the initial compatibility waste to the compatibility scheme to obtain the first scheme A1;

[0035] The specific method is as follows:

[0036] S41 compares the average value of the first difference maximum element of each of the pallet wastes with the target value to obtain the average value that is closest to the target value, and obtains the target average value;

[0037] S42 adds the pallet waste corresponding to the target average value and the initial compatibility waste to the compatibility scheme to obtain the first scheme.

[0038] S5 compares each element of the first scheme with the matching target to obtain the second element with the largest difference, and repeats steps S3 to S4 to obtain the second scheme A2.

[0039] S6 compares the second scheme with the target weight and target range to obtain the comparison results, and generates the final scheme based on the comparison results.

[0040] Specifically, the second scheme is compared with the target weight and target range. If the second scheme reaches the target weight and target range, the matching is stopped and the final scheme is obtained. If the second scheme does not reach the target weight and target range, each element of the second scheme is calculated and compared with the matching target to obtain the third element with the largest difference. Steps S3 to S4 are repeated to obtain the third scheme for comparison again. This process is repeated until the scheme reaches the target weight and the final scheme is obtained.

[0041] When comparing the proposed solution with the target weight, the weight of the pallet needs to be added to the target weight, or the weight of the pallet needs to be subtracted from the proposed solution.

[0042] Picking begins sequentially based on the matching scheme. For the next material to be added to the matching scheme, the content of each element in the current scheme is recalculated based on the previous n waste information entries (excluding the first one). This content is compared with the matching target to identify the element with the largest discrepancy. The next round of picking then begins to find the next target material for matching. This process continues, continuously generating the next target material to join the matching scheme.

[0043] The main principles of waste compatibility can be summarized as follows:

[0044] (1) Analysis and identification of the properties of hazardous waste to ensure compatibility of the mixed wastes. The premise of hazardous waste compatibility is to ensure the compatibility of the mixed wastes, thereby avoiding safety accidents during the incineration process; specifically, it means that when two or more hazardous wastes are mixed, large amounts of heat or high pressure, severe flames, explosions, flammable gases, toxic gases, and violent polymerization reactions should be avoided; in addition, the compatibility between waste and container, waste material and silo, and furnace lining must also be ensured to avoid damage to the equipment. This plan is formulated on the basis that sufficient safety measures have been fully considered for the material pit and incineration device at the project site.

[0045] (2) Ensure the stability of the calorific value of waste feedstock. The feedstock should be formulated so that the calorific value entering the incinerator is as close as possible to the design range. If the calorific value is too low, the auxiliary burner needs to be started to maintain the required furnace temperature, which will increase the operating cost. If the calorific value is too high, the incinerator's processing capacity will decrease and may lead to overheating.

[0046] (3) Control the content of acidic pollutants, heavy metals, and alkali metals in the feed. Control the content of acidic pollutants in the waste to ensure that the incineration equipment is not corroded and that the exhaust gas meets emission standards; control the content of heavy metals to ensure that the heavy metal content in the exhaust gas meets emission standards; control the content of alkali metals to ensure that the material does not melt and coke and stick to the wall due to the high content of alkali metal salts in the material during operation, which will affect the stable operation of the incinerator. In addition, alkali metal oxides are produced after combustion, which are prone to explosion when they come into contact with water during slag discharge. Alkali metals usually exist in hazardous waste in the form of inorganic salts or organic salts.

[0047] (4) Appropriate crushing and mixing pretreatment to maintain the continuity and stability of incineration.

[0048] The above-disclosed embodiments are merely preferred embodiments of a dynamic compatibility method for hazardous waste according to the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present invention are still within the scope of the invention.
