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.

[0018] The following description, in conjunction with the accompanying drawings, details a desulfurization load performance evaluation method, electronic device, and storage medium provided by the present invention through specific embodiments and application scenarios.

[0019] Example 1:

[0020] Reference Figure 1 , Figure 1 This illustration shows a desulfurization load performance evaluation method provided by a first aspect embodiment of the present invention, applied to a coke oven gas purification device. The method is also applied to and executed by an electronic device. In other words, the method can be executed by software or hardware installed on the electronic device, and the method includes the following steps: Step S110: Obtain the sulfur content of raw coal, sulfur carryover rate of coal gas, number of coke outlets per day, weight of coal cake per outlet, and coal gas production per ton of raw coal.

[0021] In this step, the sulfur content of raw coal refers to the mass fraction of sulfur in the raw coal, usually expressed as a percentage.

[0029] It should be noted that the unit of desulfurization load is... The unit for the hourly production of raw coal gas is h, the unit for hydrogen sulfide content in raw coal gas is .

[0030] In related technologies, the desulfurization load of a coke oven gas purification unit is calculated by measuring the amount of gas before the purification unit and the H2S content in the gas after coking coal blending. The desulfurization effect is then calculated by measuring the H2S content in the gas after the purification unit. However, this method of calculating the desulfurization load relies on operational data during production and lacks specific calculation methods and models. This leads to the possibility of exceeding the processing capacity of the coke oven gas purification unit and affecting the H2S content in the purified gas. The problem is that the content exceeds the standard and does not meet quality requirements; and it is necessary to regularly test the gas for its content. The content calculation of the desulfurization load of the coke oven gas purification unit has a large time lag in the test data, which cannot effectively guide the operation of coking coal blending and coke oven gas purification unit.

[0031] Therefore, the desulfurization load performance evaluation method provided in this embodiment of the invention obtains the sulfur content of raw coal, sulfur carryover rate of coal gas, number of coking holes per day, weight of coal cake per hole, and raw coal gas production per ton of raw coal. Based on the number of coking holes per day, weight of coal cake per hole, and raw coal gas production per ton of raw coal, the hourly raw coal gas production is calculated. Based on the sulfur content of raw coal and sulfur carryover rate of coal gas, the hydrogen sulfide content of raw coal gas is determined. Based on the hydrogen sulfide content of raw coal gas and the hourly raw coal gas production, the desulfurization load of the coke oven gas purification device is determined. This application, through this method, can accurately predict the desulfurization load of the coke oven gas purification device, and use this to formulate production control parameters for the coke oven gas purification device, improve the qualification rate of coke oven gas, and has the purpose of pre-guiding production operations. It maximizes the desulfurization load handling capacity of the coke oven gas purification device, improves the level of coking management technology and the quality of coke oven gas, and avoids the need for manual detection of gas components. The content was used to calculate the lag of the desulfurization load of the coke oven gas purification unit.

[0034] In this step, the volatile matter content of the raw coal is obtained based on the volatile matter content of individual coal types and their proportions (volatile matter is dry ash-free volatile matter); the density of the raw coal gas ranges from 0.45 to 0.50. The value range of the coal type coefficient is 3 to 3.3.

[0035] Step S212: Determine the amount of raw coal gas produced per ton of raw coal based on the density of the raw coal gas, the volatile matter content of the raw coal, and the coal type coefficient.

[0036] In one possible implementation, the formula for calculating the amount of gas produced per ton of raw coal is as follows: , in, This indicates the amount of gas produced per ton of raw coal. Indicates the coal type coefficient. Indicates the volatile matter content of a single type of coal. Indicates the density of raw coal gas. This indicates the proportion of a single type of coal in the blend.

[0037] Step S221: Obtain the sulfur content of a single type of coal after coking and the coking rate of the raw coal.

[0038] In this step, the sulfur content of a single type of coal after coking is calculated based on the sulfur content of the raw coal and the residual sulfur content of the raw coal.

[0039] Step S222: Determine the sulfur carry-over rate of coal gas based on the sulfur content of raw coal, the sulfur content of single coal after coking, and the coking rate of raw coal of single coal.

[0040] In one possible implementation, the sulfur content of the raw coal is the air-dried sulfur content of a single type of coal.

[0041] In this step, the formula for calculating the sulfur carryover rate of the coal gas is as follows: N Where N represents the sulfur carryover rate of the coal gas. This indicates the proportion of a single type of coal in the blend. Indicates the volatile matter content of a single type of coal. This represents the ratio of the sulfur content of a single type of coal after coking to the sulfur content of the single type of coal. This formula represents the overall coking rate of the raw coal.

[0042] Step S231: Obtain the total number of holes in the coke oven and the coke oven turnaround time.

[0043] Step S232: Determine the number of coke oven holes per day based on the total number of holes in the coke oven and the coke oven turnover time.

[0045] Step S240: Obtain the sulfur content of the raw coal and the weight of the single-hole coal cake.

[0046] This step can be adopted. Figure 1 The description of step S110 in the embodiment will not be repeated here.

[0047] Step S250: Calculate the hourly raw coal gas production based on the number of coke outlets per day, the weight of coal cake per outlet, and the amount of raw coal gas produced per ton of raw coal.

[0048] This step can be adopted. Figure 1 The description of step S120 in the embodiment will not be repeated here.

[0049] Step S260: Determine the amount of hydrogen sulfide in the raw coal gas based on the sulfur content of the raw coal and the sulfur carrying rate of the coal gas.

[0051] Step S270: Determine the desulfurization load of the coke oven gas purification unit based on the amount of hydrogen sulfide in the raw coal gas and the hourly production of raw coal gas.

[0052] This step can be adopted. Figure 1 The description of step S140 in the embodiment will not be repeated here.

[0053] In one possible implementation method, the formula for calculating the desulfurization load is as follows: , in, Indicates desulfurization load, This indicates the total number of holes in the coke oven. This indicates the weight of the coal cake per hole. Indicates the coefficient for a single coal type. This indicates the proportion of a single type of coal in the blend. Indicates the volatile matter content of a single type of coal. Indicates coke oven turnaround time. Indicates the density of raw coal gas. Indicates the sulfur content of a single type of coal. This represents the ratio of the sulfur content of a single type of coal after coking to the sulfur content of the single type of coal itself. In related technologies, the desulfurization load of a coke oven gas purification unit is calculated by measuring the amount of gas before the purification unit and the H2S content in the gas after coking coal blending. The desulfurization effect is then calculated by measuring the H2S content in the gas after the purification unit. However, this method of calculating the desulfurization load relies on operational data during production and lacks specific calculation methods and models. This leads to the possibility of exceeding the processing capacity of the coke oven gas purification unit and affecting the H2S content in the purified gas. The problem is that the content exceeds the standard and does not meet quality requirements; and it is necessary to regularly test the gas for its content. The content calculation of the desulfurization load of the coke oven gas purification unit has a large time lag in the test data, which cannot effectively guide the operation of coking coal blending and coke oven gas purification unit.

[0054] The desulfurization load performance evaluation method provided in this invention obtains the raw coal gas density, raw coal volatile matter, and coal type coefficient. Based on these parameters, it determines the raw coal gas production per ton of raw coal. It also obtains the sulfur content and coking rate of a single type of coal after coking. Based on the sulfur content, coking rate, and coking rate of the raw coal, it determines the gas flow carrying capacity. Furthermore, it obtains the total number of coke oven holes and the coke oven turnover time. Based on this, it determines the number of coke oven holes per day. Finally, it obtains the sulfur content and weight of a single-hole coal cake. Based on the number of coke oven holes per day, the weight of a single-hole coal cake, and the raw coal gas production per ton of raw coal, it calculates the hourly raw coal gas production. Based on the sulfur content and sulfur carrying capacity of the raw coal, it determines the hydrogen sulfide content in the raw coal gas. Finally, based on the hydrogen sulfide content and hourly raw coal gas production, it determines the desulfurization load of the coke oven gas purification device. This application utilizes a method to accurately predict the desulfurization load of a coke oven gas purification unit, thereby determining the production control parameters for the unit, improving the pass rate of coke oven gas, and providing advance guidance for production operations. This maximizes the desulfurization load handling capacity of the coke oven gas purification unit, enhances coking management technology, and improves the quality of coke oven gas, while avoiding the need for manual detection of gas components. The content was used to calculate the lag of the desulfurization load of the coke oven gas purification unit.

[0055] An exemplary embodiment of the desulfurization load performance evaluation method applied to calculate the desulfurization load of a coke oven gas purification unit: A coke oven gas purification unit in a coking plant has a designed gas processing capacity of 155,000 m³ / h, a designed hydrogen sulfide content before the purification unit of 10 g / m³, and a designed hydrogen sulfide content after the purification unit of ≤0.25 g / m³. The desulfurization load of the coke oven gas purification unit designed for this coking plant is calculated using the desulfurization load performance evaluation method of this application as follows: 1 ) That is, the maximum design load of the desulfurization load of the coke oven gas purification unit in the coking plant is 1.55 t / h.

[0056] The table below shows the desulfurization load calculation model established using the desulfurization load performance evaluation method:

[0057] Using the desulfurization load performance evaluation method, one production line of this coking plant produces coke 1, and another produces coke 2. The calculated hourly raw coal gas production is 153,046 m³. 3 The hydrogen sulfide concentration in the raw coal gas was 10661 mg / m³. 3The desulfurization load is 1.63 t / h (>1.55 t / h), which exceeds the desulfurization load capacity of the coke oven gas purification unit. The H2S content of the purified gas is at risk of exceeding the standard (≥0.25 g / m3), which cannot meet the downstream methanol coke oven gas to methanol production conditions. The unqualified coke oven gas is released through flare ignition, resulting in gas loss.

[0058] Based on this, the quality of coal fed into the furnace or the type of coke can be adjusted using the desulfurization load prediction model in the table below to meet the desulfurization load capacity of the downstream coke oven gas purification unit:

[0059] By adjusting the quality of the coal or the type of coke fed into the coking plant, the following can be achieved: Under the condition that the original coke type remains unchanged, by adjusting the quality of raw coal, the hourly raw coal gas production is calculated to be 153,046 m³. 3 The hydrogen sulfide content in the raw coal gas is 9904 mg / m³. 3 The desulfurization load is 1.52 t / h (<1.55 t / h), which meets the desulfurization load capacity of the downstream gas purification unit.

[0060] By adjusting the coke type on one production line to produce coke 1 and coke 3, the calculated hourly raw coal gas production is 151715 m³. 3 The hydrogen sulfide content in the raw coal gas is 10102 mg / m³. 3 The desulfurization load is 1.53 t / h (<1.55 t / h), which meets the desulfurization load capacity of the downstream gas purification unit.

[0061] Using the above calculation method, the quality of raw coal or coke type can be adjusted to meet the desulfurization load capacity of the downstream coke oven gas purification unit, so that the purified gas meets the quality requirements.
