[0043] This application considers the difficulty of directly measuring the chlorine content in blast furnace gas. However, HCl rapidly dissolves in the gas condensate as the gas temperature decreases. Other acidic gases are either low in content and weakly acidic (such as hydrogen sulfide (H2S)) or weakly acidic and low in solubility (such as carbon dioxide (CO2)). The pH of the blast furnace gas condensate is directly related to the amount of dissolved HCl gas in the gas. Therefore, the dechlorination effect of the blast furnace gas can be determined using the blast furnace gas condensate.

[0044] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions of this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0045] An embodiment of the present application provides a dechlorination effect detection method, the execution subject of which may be an electronic device, for example, a controller. The following description will be made using the controller as an example in which the execution subject of the method is a controller. Figure 1 This is a flow chart of the dechlorination effect detection method provided in the embodiment of the present application. Figure 1 , the method may include:

[0046] Step 110: Acquire a first blast furnace gas detection sample in real time; the temperature of the first blast furnace gas detection sample is higher than a first temperature threshold, and the pressure of the first blast furnace gas detection sample is higher than a first pressure threshold;

[0047] Step 120: decompress the first blast furnace gas test sample to obtain a second blast furnace gas test sample; the pressure of the second blast furnace gas test sample is lower than a second pressure threshold;

[0048] Step 130: condense the second blast furnace gas test sample to obtain blast furnace gas condensate;

[0049] Step 140: Determine the dechlorination effect of the blast furnace gas based on the blast furnace gas condensate.

[0050] In step 110, the controller can obtain blast furnace gas in real time and take an appropriate amount of blast furnace gas as a first blast furnace gas detection sample. The first blast furnace gas detection sample is in a high temperature and high pressure state, that is, the temperature of the first blast furnace gas detection sample is higher than a first temperature threshold, and the pressure of the first blast furnace gas detection sample is higher than a first pressure threshold.

[0051] In step 120, the controller may reduce the pressure of the first blast furnace gas test sample using the high-pressure blast furnace gas pressure reducing device to obtain a second blast furnace gas test sample. The first blast furnace gas test sample and the second blast furnace gas test sample have different pressures but the same temperature. The pressure of the second blast furnace gas test sample is lower than a second pressure threshold.

[0052] In step 130, the controller condenses the second blast furnace gas test sample using a low-pressure blast furnace gas condensation device. After the decompression process, the second blast furnace gas passes through the condensation device at a moderate velocity, allowing for sufficient condensation to produce blast furnace gas condensate. The cooled gas can then be transported to the low-pressure gas pipeline network for recycling.

[0053] In step 140 , the controller may determine the dechlorination effect of the blast furnace gas by testing the pH value of the blast furnace gas condensate.

[0054] The dechlorination effect detection method provided in the embodiment of the present application obtains blast furnace gas condensate by decompressing and rapidly condensing a blast furnace gas detection sample obtained in real time and subjected to decompression treatment, and then determines the dechlorination effect of the blast furnace gas through the blast furnace gas condensate. The dechlorination effect of the blast furnace gas can be detected quickly and accurately in real time, with a high degree of automation, thereby effectively guiding the production and recovery process of the blast furnace gas and ensuring production safety.

[0055] In some embodiments, the dechlorination effect of blast furnace gas is determined based on blast furnace gas condensate, including: determining a target pH value of the blast furnace gas condensate; determining the dechlorination effect of the blast furnace gas based on the target pH value; the target pH value is proportional to the dechlorination effect of the blast furnace gas.

[0056] The controller can detect and determine the target pH value of blast furnace gas condensate, such as through electrochemical methods, chemical indicator methods, spectroscopy, etc. The lower the target pH value, the more acidic the blast furnace gas condensate, the higher the chlorine content, and the poorer the desulfurization effect. The higher the target pH value, the weaker the acidity of the blast furnace gas condensate, the lower the chlorine content, and the better the desulfurization effect.

[0057] The dechlorination effect detection method provided in the embodiment of the present application obtains blast furnace gas condensate water by decompressing and condensing a blast furnace gas detection sample that has been subjected to decompression treatment, and then determines the dechlorination effect of the blast furnace gas by determining the target pH value of the blast furnace gas condensate water. The dechlorination effect of the blast furnace gas can be detected quickly and accurately, thereby effectively guiding the production and recovery process of the blast furnace gas and ensuring production safety.

[0058] In some embodiments, determining the target pH value of blast furnace gas condensate water includes: detecting the pH of the blast furnace gas condensate water multiple times to obtain multiple pH values; calculating the average value of the multiple pH values; if the average value is within a preset range, using the average value as the target pH value.

[0059] The controller can use a continuous online pH monitoring device to repeatedly test the pH of the blast furnace gas condensate, obtaining multiple pH values. The controller then calculates the average of these pH values ​​and uses the average as the target pH value when it is within a preset range. The preset range is the reasonable pH range for dechlorinated blast furnace gas and is determined based on actual production conditions.

[0060] The dechlorination effect detection method provided in the embodiment of the present application determines the target pH value of blast furnace gas condensate water by multiple detections, taking an average value, and judging the relationship between the average value and a preset range. This can fully ensure the accuracy of the target pH value, thereby accurately reflecting the dechlorination effect of blast furnace gas, effectively guiding the production and recovery process of blast furnace gas, and ensuring production safety.

[0061] In some embodiments, the dechlorination effect detection method further includes: if the average value is not within a preset range, determining the cause of the abnormality; if the cause of the abnormality is that the step of obtaining blast furnace gas condensate water through condensation treatment is abnormal, re-obtaining the blast furnace gas condensate water; based on the re-obtained blast furnace gas condensate water, redetermining the target pH value; if the cause of the abnormality is that the step of obtaining the pH value by detecting the acidity and alkalinity of the blast furnace gas condensate water is abnormal, re-detecting the pH value of the blast furnace gas condensate water; based on the re-detected pH value, redetermining the target pH value.

[0062] If the average value is outside the preset range, the controller can determine the cause of the abnormality. The abnormality may be caused by an abnormality in the step of obtaining blast furnace gas condensate through condensation treatment, or by an abnormality in the step of detecting the pH value of the blast furnace gas condensate. For example, if the controller detects that the temperature change of the blast furnace gas test sample before and after the condensation treatment is less than the preset value, it can be determined that the condensation treatment step is abnormal; if the controller detects that multiple pH values ​​of different blast furnace gas condensates detected by the pH value detection device are the same, it can be determined that the pH value detection step is abnormal.

[0063] If the cause of the abnormality is an abnormality in the step of obtaining blast furnace gas condensate through condensation, the controller can use a non-faulty condensing device to re-obtain blast furnace gas condensate, and then re-determine the target pH value based on the re-obtained blast furnace gas condensate. If the cause of the abnormality is an abnormality in the step of obtaining the pH value by detecting the pH value of the blast furnace gas condensate, the controller can use a non-faulty pH value detection device to re-detect the pH value of the blast furnace gas condensate, and then re-determine the target pH value based on the re-detected pH value.

[0064] The dechlorination effect detection method provided in the embodiment of the present application determines the cause of the abnormality when the average pH value of the blast furnace gas condensate is not within a preset range, and after determining the cause of the abnormality, redetermines the target pH value, which can fully ensure the accuracy of the target pH value, thereby accurately reflecting the dechlorination effect of the blast furnace gas, effectively guiding the production and recovery process of the blast furnace gas, and ensuring production safety.

[0065] In some embodiments, the second blast furnace gas detection sample is condensed to obtain blast furnace gas condensate water, including: determining a target amount of cooling water based on the temperature of the first blast furnace gas detection sample; introducing the target amount of cooling water and the second blast furnace gas detection sample into a condensation device; in the condensation device, cooling the second blast furnace gas detection sample by cooling water; when the temperature of the second blast furnace gas detection sample is lower than a second temperature threshold, obtaining blast furnace gas condensate water.

[0066] The controller can perform condensation processing using a condensation device. Specifically, the controller can determine the target amount of cooling water based on the temperature of the first blast furnace gas test sample. The controller then introduces the target amount of cooling water and the second blast furnace gas test sample into the condensation device. In the condensation device, the cooling water and the second blast furnace gas test sample are separated into different channels to achieve heat exchange with the high-temperature gas. When the temperature of the second blast furnace gas test sample drops below the dew point, condensed water is precipitated, which is the blast furnace gas condensate. The cooling water is recycled and reused through a recovery pipeline.

[0067] The dechlorination effect detection method provided in the embodiment of the present application obtains blast furnace gas condensate water by decompressing and condensing a blast furnace gas detection sample that has been subjected to decompression treatment, and then determines the dechlorination effect of the blast furnace gas by determining the target pH value of the blast furnace gas condensate water. This method can achieve rapid condensation of blast furnace gas and real-time monitoring of blast furnace gas condensate water, and quickly and accurately detect the dechlorination effect of blast furnace gas, thereby effectively guiding the production and recovery process of blast furnace gas and ensuring production safety.

[0068] In some embodiments, the dechlorination effect detection method further includes: if the dechlorination effect of blast furnace gas is lower than the expected dechlorination effect, issuing a warning message, and increasing the spraying amount of the dechlorination agent of the dechlorination system based on a preset relationship table to optimize the dechlorination effect of blast furnace gas; the preset relationship table is a correspondence table between the dechlorination agent and the dechlorination amount.

[0069] The controller can pre-register a table that maps the dechlorination system's dechlorination agent to the amount of dechlorination. If the dechlorination efficiency of blast furnace gas falls short of expectations, it issues a warning and, based on the preset relationship table, increases the dechlorination system's dechlorination agent output to optimize the dechlorination effect. Warning messages can include text, voice, and lighting information. The text and voice messages explain the reason for the warning, while lighting information can include color and flashing information.

[0070] The dechlorination effect detection method provided in the embodiment of the present application issues a warning message when the dechlorination effect of blast furnace gas is lower than the expected dechlorination effect, and increases the spray rate of the dechlorinating agent, which can attract the attention of the staff and optimize the dechlorination effect. In addition, the method has flexible adjustment, high degree of automation, high safety performance, high detection accuracy, and fast chain reaction. It can be organically coupled with the blast furnace gas dechlorination system to realize the chain adjustment function and ensure production safety.
