[0031] Example 1

[0032] Figure 1 This is a flow chart of a parameter configuration method for a flue gas purification device provided in Example 1 of the present invention. This embodiment is applicable to desulfurization purification operations on the flue gas of a hot blast furnace. The method can be executed by a parameter configuration device of the flue gas purification device. The parameter configuration device of the flue gas purification device can be implemented in the form of hardware and / or software. The parameter configuration device of the flue gas purification device can be configured in a terminal or server with a flue gas purification function.

[0033] like Figure 1 As shown, the method includes:

[0034] S110: Obtain a current value of at least one configuration parameter of the flue gas purification device and a detection result of a current flue gas inlet concentration.

[0035] The configuration parameters include: flue gas treatment capacity coefficient, flue gas inlet concentration coefficient, reactant reaction efficiency coefficient and reactant given coefficient.

[0036] Wherein, the flue gas purification device can be as follows Figure 2The device shown can purify hot blast furnace flue gas using a dry desulfurization purification process. Furthermore, the dry desulfurization purification process involves the simultaneous injection of finely powdered reactants after the flue gas enters the flue gas purification device. The reactants, stimulated by the high temperature of the flue gas, expand in volume, and decompose into highly reactive and adsorbent substances. These adsorbent substances, after being highly mixed with the flue gas, react with acidic gases such as SO2, SO3, and HCl to form sodium salts such as sodium sulfate, thereby removing the majority of the sulfur in the flue gas and achieving the purpose of flue gas purification.

[0037] like Figure 2 As shown, the flue gas purification device includes: a hot blast furnace, a chimney, an inlet flue gas component detection component, a reactant blowing system, a flue gas intake pipe, a flue gas return pipe, a coal injection pulverizing system, an induced draft fan, a hot blast furnace flue, a bag dust collector, a chimney and a flue damper plate; further, in this embodiment, the detection result of the current flue gas inlet concentration is obtained by the inlet flue gas component detection component; the actual value of the flue gas outlet concentration is obtained by the outlet flue gas component detection component; further, the detection result of the current flue gas inlet concentration is the SO2 concentration in the flue gas currently passing through the inlet flue gas component detection component; correspondingly, the actual value of the flue gas outlet concentration is the SO2 concentration in the flue gas currently passing through the outlet flue gas component detection component.

[0038] In this embodiment, the flue gas treatment capacity coefficient is a value set according to different production states of the hot blast stove; specifically, the setting value of the flue gas treatment capacity coefficient can be C 烟气处理量1~N =0.6~1.2; further, under the normal production state of the hot blast furnace, the flue gas treatment capacity coefficient takes the upper limit value of 1.2, and under the restricted or controlled production state of the hot blast furnace, the flue gas treatment capacity coefficient takes the lower limit value of 0.6.

[0039] Furthermore, the flue gas inlet concentration coefficient can be set according to the daily average value of SO2 concentration in the flue gas that has not undergone purification operation; further, the setting value of the flue gas inlet concentration coefficient can be C 烟气入口浓度系数 =0.5~1.6.

[0040] Furthermore, the reactant efficiency coefficient can be set according to the reactant level; specifically, the value of the reactant efficiency can be: C 反应物效率系数 =0.5~2.0, if the activity level of the reactants is low, the particle size is coarse, and the desulfurization quality content level is low, C 反应物效率系数 The lower limit is 0.5, otherwise the upper limit is 2.0.

[0041] Correspondingly, the reactant given coefficient can be set to a conventional comprehensive adjustment coefficient: 0.5~2.0. When other parameters are set according to actual conditions, the flue gas purification device can be comprehensively adjusted by the reactant given coefficient, that is, the reactant given amount is directly adjusted according to the flue gas outlet concentration requirement value of the flue gas purification device.

[0042] S120 , determining an initial injection amount of the reactant of the flue gas purification device according to the current value of each configuration parameter, the required flue gas outlet concentration value of the flue gas purification device, the flue gas processing volume, and the reaction time value.

[0043] Among them, the flue gas outlet concentration requirement value is a value set according to the production requirement value or the environmental protection requirement value. Further, the flue gas outlet concentration requirement value N SO2 = production requirement or environmental protection requirement value - (2 to 5), which can be manually set according to production and environmental protection requirements.

[0044] Furthermore, the flue gas treatment capacity is the flue gas capacity generated by the hot blast furnace burning unequal amounts of coal gas; specifically, determining the flue gas treatment capacity of the flue gas purification device includes: obtaining the current coal gas capacity of the flue gas purification device; calculating the flue gas treatment capacity based on the current coal gas capacity and a preset formula; wherein the preset formula is: V 烟气处理量 = current gas volume * (1.4-1.75); further, the gas volume can be taken as the hourly average statistical value of the gas of the hot blast furnace; specifically, the gas consumption is small in the early combustion stage, large in the middle combustion stage, and the gas consumption is controlled to be small in the later combustion control stage, that is, the gas volume fluctuates widely during the entire reaction process. The gas volume can be the hourly average statistical value of the gas, which is a fixed value that can be calculated manually and does not fluctuate during the reaction process.

[0045] Furthermore, the reaction time value can be set according to the effective reaction length of the reactants sprayed into the flue pipe, the flue gas flow rate in the flue, and the negative pressure conditions in the bag; wherein, the reaction time value can range from 60 to 600 seconds; for example, if the initial reaction time of the reactants sprayed into the flue pipe is ≧2.5 to 3.5 seconds, the flue gas flow rate in the flue is ≧18 to 25 m / s, and the pressure in the bag is ≧-5 to 8 kPa, then the reaction time value can be taken as the lower limit of 60 seconds; correspondingly, if a new desulfurization purification system is put into operation, since the dust bag in the secondary reaction place of the reactants and the flue gas does not have a reaction environment in a short time, the reaction time is taken as the upper limit of 600 seconds.

[0046] In this embodiment, the flue gas purification device can automatically determine the initial injection amount of the reactant of the flue gas purification device based on the current value of each configuration parameter, the flue gas outlet concentration requirement value of the flue gas purification device, the flue gas processing volume and the reaction time value; wherein, the initial injection amount of the reactant is the initial hourly supply amount of the reactant during the flue gas purification process; wherein, the reactant can be a desulfurizer; further, the desulfurizer can be an agent for removing free sulfur or sulfur compounds in fuel, raw materials or other materials, and in the control and treatment of pollutants, it mainly refers to the agent used to remove sulfur oxides in exhaust gas.

[0047] S130 , obtaining an actual value of the flue gas outlet concentration of the flue gas purification device under the action of the initial injection amount of the reactants.

[0048] In this embodiment, if Figure 2 As shown, the flue gas outlet concentration detection component is connected to the chimney to detect the actual value of the flue gas outlet concentration in the flue gas after the purification operation discharged through the chimney, that is, the actual value of the SO2 concentration in the flue gas after the purification reaction and before the flue gas is finally discharged.

[0049] S140 , adjusting the parameter values ​​of various configuration parameters using preset parameter adjustment rules according to the detection result of the current flue gas inlet concentration of the flue gas purification device and the relationship between the actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration.

[0050] Among them, the size relationship includes: the detection result of the current flue gas inlet concentration is greater than the actual value of the flue gas outlet concentration, the detection result of the current flue gas inlet concentration is equal to the actual value of the flue gas outlet concentration, and the detection result of the current flue gas inlet concentration is less than the actual value of the flue gas outlet concentration; further, if the detection result of the current flue gas inlet concentration is equal to the actual value of the flue gas outlet concentration, the current reactant injection amount of the current purification reaction is equal to the required reactant injection amount. At this time, there is no need to adjust the parameter values ​​of each configuration parameter, and the current flue gas purification operation can be continued according to the current values ​​of each configuration parameter; accordingly, if the detection result of the current flue gas inlet concentration is not is equal to the actual value of the flue gas outlet concentration, then the current reactant injection amount of the current purification reaction is not equal to the required reactant injection amount, that is, it is necessary to use the preset parameter adjustment rules to adjust the parameter values ​​of each configuration parameter to adjust the reactant injection amount; specifically, if the detection result of the current flue gas inlet concentration is greater than the actual value of the flue gas outlet concentration, it means that the current reactant injection amount is large and there is unnecessary waste of reactants. Therefore, it is necessary to adjust the parameter values ​​of each configuration parameter to reduce the reactant injection amount. Otherwise, it means that the current reactant injection amount is small and cannot meet the flue gas purification requirements, so the reactant injection amount needs to be increased.

[0051] The technical solution of the embodiment of the present invention first obtains the current value of at least one configuration parameter of the flue gas purification device and the detection result of the current flue gas inlet concentration, and then determines the initial injection amount of the reactant of the flue gas purification device according to the current value of each configuration parameter, the required value of the flue gas outlet concentration of the flue gas purification device, the flue gas processing volume and the reaction time value, and obtains the actual value of the flue gas outlet concentration of the flue gas purification device under the action of the initial injection amount of the reactant, and finally, according to the detection result of the current flue gas inlet concentration of the flue gas purification device and the relationship between the actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration, the preset parameter adjustment rules are used to adjust the parameter values ​​of each configuration parameter, thereby realizing automatic adjustment of the parameters of the flue gas purification device, reducing the consumption of reactants while ensuring the purification efficiency, improving the economy of the flue gas purification work, and reducing the working cost of the flue gas purification operation.

[0052] Example 2

[0053] Figure 3 A flow chart of a parameter configuration method for a flue gas purification device provided in Example 2 of the present invention. This embodiment is refined based on the above-mentioned embodiment. In this embodiment, the method of adjusting the parameter values ​​of each configuration parameter using preset parameter adjustment rules based on the detection results of the current flue gas inlet concentration of the flue gas purification device and the relationship between the actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration is specifically refined.

[0054] like Figure 3 As shown, the method includes:

[0055] S310: Obtain a current value of at least one configuration parameter of the flue gas purification device and a detection result of a current flue gas inlet concentration.

[0056] The configuration parameters include: flue gas treatment capacity coefficient, flue gas inlet concentration coefficient, reactant reaction efficiency coefficient and reactant given coefficient.

[0057] S320: Determine the initial injection amount of the reactant of the flue gas purification device according to the current value of each configuration parameter, the required flue gas outlet concentration value of the flue gas purification device, the flue gas processing volume and the reaction time value.

[0058] S330: Obtain the actual value of the flue gas outlet concentration of the flue gas purification device under the action of the initial injection amount of the reactants.

[0059] S340: When the current smoke inlet concentration is detected, the adjustment priority order of each configuration parameter is determined according to the relationship between the actual smoke outlet concentration value and the required smoke outlet concentration value.

[0060] Specifically, according to the relationship between the actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration, the adjustment priority order of each configuration parameter is determined, including: if the actual value of the flue gas outlet concentration is greater than the required value of the flue gas outlet concentration, then the configuration parameters are determined to be sorted in descending order of adjustment priority as the reactant given coefficient, the reactant reaction efficiency coefficient, the flue gas inlet concentration coefficient and the flue gas treatment volume coefficient; if the actual value of the flue gas outlet concentration is less than the required value of the flue gas outlet concentration, then the configuration parameters are determined to be sorted in descending order of adjustment priority as the reactant given coefficient, the flue gas inlet concentration coefficient, the reactant reaction efficiency coefficient and the flue gas treatment volume coefficient.

[0061] Furthermore, based on the detection results of the current flue gas inlet concentration of the flue gas purification device and the relationship between the actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration, the preset parameter adjustment rules are used to adjust the parameter values ​​of each configuration parameter, which also includes: when it is determined that the current flue gas inlet concentration is not detected, the configuration parameters are determined to be sorted in order of adjustment priority from large to small as the reactant given coefficient, the flue gas inlet concentration coefficient and the flue gas treatment volume coefficient; according to the adjustment priority order of each configuration parameter and the relationship between the actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration, the parameter values ​​of each configuration parameter are adjusted by at least one detection and at least one feedback adjustment.

[0062] Among them, the method of at least one detection and at least one feedback adjustment can be: when the configuration parameters are adjusted according to the priority order of the above-mentioned parameter adjustment, each parameter adjustment will match the result of the detection and feedback adjustment after the parameter adjustment; for example, if the actual value of the flue gas outlet concentration is greater than the required value of the flue gas outlet concentration, the reactant given coefficient is first increased in order of priority, and the increased reactant given coefficient is used as the current new reactant given coefficient, and the updated reactant given coefficient and the initial reactant reaction efficiency coefficient, flue gas inlet concentration coefficient and flue gas treatment efficiency coefficient are used. The reactant injection volume is updated by the physical coefficient, and the current actual value of the flue gas outlet concentration under the updated injection volume is re-tested, and finally the current actual value of the flue gas outlet concentration is compared with the required value of the flue gas outlet concentration; if the actual value of the flue gas outlet concentration is equal to the required value of the flue gas outlet concentration at this time, the updated flue gas inlet concentration coefficient is kept unchanged, and the flue gas purification operation is continued; if the actual value of the flue gas outlet concentration is still greater than the required value of the flue gas outlet concentration at this time, the reactant reaction efficiency coefficient is adjusted in order of priority, and the above operation is repeated until the actual value of the flue gas outlet concentration is equal to the required value of the flue gas outlet concentration.

[0063] S350 , adjusting the parameter value of each configuration parameter according to the adjustment priority order and the size relationship of each configuration parameter by adopting at least one detection and at least one feedback adjustment method.

[0064] In this embodiment, according to the adjustment priority order of each configuration parameter and the size relationship, the parameter value of each configuration parameter is adjusted by at least one detection and at least one feedback adjustment, including: obtaining the target configuration parameter for current adjustment according to the adjustment priority order of each configuration parameter; increasing or decreasing the target configuration parameter according to the size relationship to obtain a new current value of the target configuration parameter; after updating the current value of each configuration parameter using the new current value of the target configuration parameter, using the updated current value of each configuration parameter to determine the new reactant injection amount of the flue gas purification device; obtaining the new actual value of the flue gas outlet concentration of the flue gas purification device under the action of the new reactant injection amount; re-detecting the new size relationship between the new actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration. If the new size relationship does not meet the end adjustment condition, returning to the operation of obtaining the target configuration parameter for current adjustment according to the adjustment priority order of each configuration parameter until the end adjustment condition is met.

[0065] Specifically, if the actual value of the flue gas outlet concentration is greater than the required value of the flue gas outlet concentration, the configuration parameters are determined to be sorted in order from large to small according to the adjustment priority, and the adjustment method is: the reactant given coefficient increases, the reactant reaction efficiency coefficient increases, the flue gas inlet concentration coefficient decreases, and the flue gas treatment volume coefficient decreases; correspondingly, if the actual value of the flue gas outlet concentration is less than the required value of the flue gas outlet concentration, the configuration parameters are determined to be sorted in order from large to small according to the adjustment priority, and the adjustment method is: the reactant given coefficient decreases, the flue gas inlet concentration coefficient increases, the reactant reaction efficiency coefficient decreases, and the flue gas treatment volume coefficient increases.

[0066] The technical solution of the embodiment of the present invention first obtains the current value of at least one configuration parameter of the flue gas purification device and the detection result of the current flue gas inlet concentration, and then determines the initial injection amount of the reactant of the flue gas purification device according to the current value of each configuration parameter, the required value of the flue gas outlet concentration of the flue gas purification device, the flue gas processing volume and the reaction time value, and obtains the actual value of the flue gas outlet concentration of the flue gas purification device under the action of the initial injection amount of the reactant. Finally, when it is determined that the current flue gas inlet concentration is detected, the adjustment priority order of each configuration parameter is determined according to the size relationship between the actual value of the flue gas outlet concentration and the required value of the flue gas outlet concentration. According to the adjustment priority order of each configuration parameter and the size relationship, the parameter value of each configuration parameter is adjusted by at least one detection and at least one feedback adjustment, so as to realize automatic adjustment of the parameters of the flue gas purification device, reduce the consumption of reactants while ensuring the purification efficiency, improve the economy of the flue gas purification work, and reduce the working cost of the flue gas purification operation.
