[0024] In some embodiments, Figure 1 A flow chart of a method for heating a steel pickling solution provided in an embodiment of the present application, such as Figure 1 As shown, a method for heating a steel pickling solution is proposed, comprising:

[0025] Step S101, during the process of the acid tank outputting the pickling liquid, the temperature of the output pipeline is detected to obtain a first temperature.

[0026] In this embodiment, the method for heating steel pickling liquid is applied to steel pickling equipment, which is equipment for implementing steel pickling process, wherein the steel pickling equipment includes an acid tank, a steam boiler, a steam valve and a heat exchanger, the acid tank is used to store the pickling liquid, the acid tank is provided with an output pipe for outputting the pickling liquid, the heat exchanger is arranged on the output pipe of the acid tank, and is used to heat the pickling liquid in the output pipe, the steam boiler is used to output steam to heat the heat exchanger, and the steam valve is used to adjust the flow rate of steam output by the steam boiler.

[0027] For example, the steel pickling equipment can realize the pickling process of steel plates.

[0028] During the process of the acid tank outputting the pickling liquid, the temperature of the output pipeline is detected to obtain a first temperature of the output pipeline, wherein the first temperature is the real-time temperature of the output pipeline.

[0029] Exemplarily, a temperature sensor may be provided on the output pipeline, and the temperature of the output pipeline may be detected by the temperature sensor.

[0030] Step S102, when the first temperature is greater than the first temperature threshold, adjusting the opening of the steam valve from the first opening to the second opening within a first time period.

[0031] When the first temperature is greater than the first temperature threshold, it means that the temperature of the output pipeline is high enough to withstand the rapid heating of the heat exchanger, and the opening of the steam valve is adjusted from the first opening to the second opening within a first time period, wherein the first time period is a preset time period, the first opening is an initial opening, and the second opening is a target opening.

[0032] It should be noted that, when the first temperature is greater than the first temperature threshold, the opening of the steam valve is adjusted from the first opening to the second opening, while ensuring that the steam boiler outputs sufficient steam to the heat exchanger, and the heat exchanger receiving the steam can heat the output pipe and the pickling liquid in the pipe, so that the temperature of the output pipe and the pickling liquid in the pipe is raised to the target temperature.

[0033] In addition, when the first temperature is greater than the first temperature threshold, the opening of the steam valve is quickly adjusted from the first opening to the second opening within the first time period, thereby ensuring the heating efficiency of the heat exchanger and further ensuring the startup efficiency of the steel pickling equipment.

[0034] Exemplarily, the first duration can be 1 minute, the first opening can be 0%, the second opening can be 100%, the target temperature can be 85 degrees Celsius, and the opening of the steam valve is adjusted from 0% to 100% within 1 minute to raise the temperature of the output pipeline and the pickling liquid in the pipeline to 85 degrees Celsius.

[0035] Step S103, when the first temperature is less than the first temperature threshold, adjusting the opening of the steam valve from the first opening to the second opening within a second time period.

[0036] When the first temperature is lower than the first temperature threshold, it indicates that the temperature of the output pipeline is too low to withstand the rapid heating of the heat exchanger, and the opening of the steam valve needs to be adjusted from the first opening to the second opening within a second time period, wherein the second time period is greater than the first time period.

[0037] Exemplarily, the second duration and the first duration may be preset durations.

[0038] It should be noted that, when the first temperature is greater than the first temperature threshold, the opening of the steam valve is slowly adjusted from the first opening to the second opening, limiting the temperature variation of the output pipeline, avoiding damage to the output pipeline, and improving the safety of the pickling solution during the heating process.

[0039] Exemplarily, the second duration can be 30 minutes, the first opening can be 0%, the second opening can be 100%, the target temperature can be 85 degrees Celsius, and the opening of the steam valve is adjusted from 0% to 100% within 30 minutes to raise the temperature of the output pipeline and the pickling liquid in the pipeline to 85 degrees Celsius.

[0040] The method for heating the steel pickling liquid in this embodiment, when the first temperature is greater than the first temperature threshold, slowly adjusts the opening of the steam valve from the first opening to the second opening, limits the temperature change range of the output pipeline, avoids damage to the output pipeline, and improves the safety of the pickling liquid during the heating process. At the same time, when the first temperature is greater than the first temperature threshold, the opening of the steam valve is quickly adjusted from the first opening to the second opening within a first time period, thereby ensuring the heating efficiency of the heat exchanger and further ensuring the startup efficiency of the steel pickling equipment.

[0041] In some embodiments, a method for heating a steel pickling solution is provided, wherein the opening of a steam valve is adjusted from a first opening to a second opening within a first time period, comprising:

[0042] Step S201, adjusting the opening of the steam valve from the first opening to the third opening within a third time period.

[0043] In this embodiment, the opening of the steam valve is adjusted from the first opening to the third opening within a third time period, wherein the third time period is a preset time period, the second opening is greater than the third opening, and the third opening is greater than the first opening.

[0044] Exemplarily, the third opening degree may be 30%.

[0045] Exemplarily, the third duration is shorter than the first duration, and the third duration may be 30 seconds.

[0046] Step S202, adjusting the opening of the steam valve from the third opening to the second opening within a fourth time period.

[0047] The opening of the steam valve is adjusted from the third opening to the second opening within a fourth time period, wherein the fourth time period is a preset time period, and the sum of the third time period and the fourth time period is equal to the first time period.

[0048] Exemplarily, the upper computer of the steel pickling equipment can control the opening of the steam valve to be adjusted from the first opening to the third opening within a third time period, and control the opening of the steam valve to be adjusted from the third opening to the second opening within a fourth time period.

[0049] The method for heating the steel pickling liquid in this embodiment quickly adjusts the opening of the steam valve from the first opening to the third opening within the third door time when the first temperature is greater than the first temperature threshold, and quickly adjusts the opening of the steam valve from the third opening to the second opening within the fourth door time, thereby ensuring the heating efficiency of the heat exchanger and further ensuring the startup efficiency of the steel pickling equipment.

[0050] In some embodiments, a method for heating a steel pickling solution is provided, wherein the opening of a steam valve is adjusted from a first opening to a second opening within a second time period, comprising:

[0051] Step S301, maintaining the opening of the steam valve at a first opening within a fifth time period;

[0061] Exemplarily, the fourth opening degree may be 5%.

[0062] Exemplarily, the sixth duration may be 7 minutes.

[0063] The opening of the steam valve is adjusted from the fourth opening to the fifth opening within the seventh time period, wherein the seventh time period is a preset time period, the fifth opening is a preset opening, and the fifth opening is greater than the fourth opening.

[0064] Exemplarily, the fifth opening degree may be 20%.

[0072] The opening of the steam valve is adjusted from the seventh opening to the second opening within a tenth time period, wherein the tenth time period is a preset time period.

[0073] Exemplarily, the tenth time period may be 15 minutes.

[0074] It should be noted that the sum of the fifth duration, the sixth duration, the seventh duration, the eighth duration, the ninth duration and the tenth duration is equal to the second duration, the second opening is greater than the seventh opening, the seventh opening is greater than the sixth opening, the sixth opening is greater than the fifth opening, the fifth opening is greater than the fourth opening, and the fourth opening is greater than the first opening.

[0075] Exemplarily, the steam valve opening is 0% within the first 3 minutes, 5% within 3 to 10 minutes, 20% within 10 to 15 minutes, 30% within 15 to 22 minutes, 50% within 20 to 30 minutes, and 100% after 30 minutes.

[0076] The method for heating the steel pickling solution in this embodiment slowly adjusts the opening of the steam valve from the first opening to the second opening when the first temperature is greater than the first temperature threshold, thereby limiting the temperature change range of the output pipeline, avoiding damage to the output pipeline, and improving the safety of the pickling solution during the heating process.

[0077] In some embodiments, a method for heating a steel pickling solution is provided. After adjusting the opening of the steam valve from the first opening to the fourth opening within the sixth time period, the method for heating the steel pickling solution further includes:

[0078] Step S401, re-detecting the temperature of the output pipeline to obtain a second temperature.

[0079] In this embodiment, after the opening of the steam valve is adjusted from the first opening to the fourth opening within the sixth time period, the temperature of the output pipeline is re-detected to obtain the second temperature, wherein the second temperature is the temperature after the output pipeline starts to be heated.

[0080] Step S402, when the second temperature is greater than the first temperature threshold, adjusting the opening of the steam valve from the fourth opening to the second opening within a first time period.

[0081] When the second temperature is greater than the first temperature threshold, it indicates that the temperature of the output pipeline is high enough to withstand the rapid heating of the heat exchanger, and the opening of the steam valve is adjusted from the first opening to the second opening within the first time period.

[0082] Exemplarily, the first temperature threshold may be 20 degrees Celsius. When the second temperature is greater than 20 degrees Celsius, it indicates that the temperature of the output pipeline is high enough to withstand rapid heating by the heat exchanger.

[0083] The method for heating the steel pickling liquid in this embodiment adjusts the opening of the steam valve from the first opening to the second opening within a first time period when the second temperature is greater than the first temperature threshold, thereby ensuring the heating efficiency of the heat exchanger and further ensuring the startup efficiency of the steel pickling equipment.

[0084] In some embodiments, a method for heating a steel pickling solution is provided. After adjusting the opening of the steam valve from a first opening to a second opening within a second time period, the method for heating the steel pickling solution further includes:

[0085] Step S501, detecting the opening of the steam valve to obtain the real-time opening of the steam valve.

[0086] In this embodiment, the opening of the steam valve is detected to obtain the real-time opening of the steam valve, wherein the real-time opening represents the real-time opening of the steam valve.

[0087] Exemplarily, a sensor is provided on the steam valve, and the opening of the steam valve is detected by the sensor to obtain the real-time opening of the steam valve.

[0088] Step S502, when the real-time opening is not equal to the second opening, the steam boiler is controlled to stop working, and the acid tank is controlled to stop outputting the pickling liquid.

[0089] When the real-time opening is not equal to the second opening, it indicates that there is a fault in the steam valve, and it is necessary to control the steam boiler to stop working and control the acid tank to stop outputting the pickling liquid.

[0090] The method for heating the steel pickling liquid in this embodiment needs to control the steam boiler to stop working and the acid tank to stop outputting the pickling liquid when the real-time opening is not equal to the second opening, so as to avoid failure of the steam valve, thereby ensuring the safety of the steel pickling equipment.

[0091] In some embodiments, a method for heating a steel pickling solution is provided. After adjusting the opening of the steam valve from a first opening to a second opening within a second time period, the method further includes:

[0092] Step S601, after a preset time period, the temperature of the output pipe is detected to obtain a third temperature.

[0093] In this embodiment, after a preset time period, the temperature of the output pipe is detected to obtain a third temperature, wherein the preset time period is a preset heating time period, and the third temperature is the temperature of the output pipe after heating.

[0094] Exemplarily, the preset duration may be 1 hour.

[0095] Step S602: When the third temperature is lower than the second temperature threshold, the steam boiler is controlled to stop working, and the acid tank is controlled to stop outputting the pickling liquid.

[0096] When the third temperature is lower than the second temperature threshold, it indicates that the temperature of the output pipeline has not reached the second temperature threshold, i.e., there is a problem with the heat exchanger, the steam boiler is controlled to stop working, and the acid tank is controlled to stop outputting the pickling liquid, wherein the second temperature threshold is higher than the first temperature threshold.

[0097] Exemplarily, the second temperature threshold may be a target temperature.

[0098] Exemplarily, the second temperature threshold may be 85 degrees Celsius.

[0099] The method for heating the steel pickling liquid in this embodiment controls the steam boiler to stop working and the acid tank to stop outputting the pickling liquid when the third temperature is lower than the second temperature threshold, thereby avoiding failure of the steam valve and the heat exchanger, and thus ensuring the safety of the steel pickling equipment.

[0100] In some embodiments, a method for heating a steel pickling solution is provided. After detecting the temperature of the output pipeline and obtaining the third temperature, the method further includes:

[0101] Step S701, when the third temperature is greater than the second temperature threshold, reduce the opening of the steam valve to make the temperature of the output pipeline equal to the second temperature threshold.

[0102] When the third temperature is greater than the second temperature threshold, it indicates that the temperature of the output pipeline exceeds the second temperature threshold, and the opening of the steam valve needs to be reduced to make the temperature of the output pipeline equal to the second temperature threshold.

[0103] In the steel pickling liquid heating method of this embodiment, when the third temperature is greater than the second temperature threshold, the opening of the steam valve is reduced to make the temperature of the output pipeline equal to the second temperature threshold, thereby avoiding the pickling liquid temperature being too high and ensuring the pickling effect of the steel.

[0110] For example, the steel pickling equipment can realize the pickling process of steel plates.

[0111] During the process of the acid tank outputting the pickling liquid, the temperature of the output pipeline is detected to obtain a first temperature of the output pipeline, wherein the first temperature is the real-time temperature of the output pipeline.

[0112] Exemplarily, a temperature sensor may be provided on the output pipeline, and the temperature of the output pipeline may be detected by the temperature sensor.

[0113] When the first temperature is greater than the first temperature threshold, it means that the temperature of the output pipeline is high enough to withstand the rapid heating of the heat exchanger, and the opening of the steam valve is adjusted from the first opening to the second opening within a first time period, wherein the first time period is a preset time period, the first opening is an initial opening, and the second opening is a target opening.

[0114] It should be noted that, when the first temperature is greater than the first temperature threshold, the opening of the steam valve is adjusted from the first opening to the second opening, while ensuring that the steam boiler outputs sufficient steam to the heat exchanger, and the heat exchanger receiving the steam can heat the output pipe and the pickling liquid in the pipe, so that the temperature of the output pipe and the pickling liquid in the pipe is raised to the target temperature.

[0115] In addition, when the first temperature is greater than the first temperature threshold, the opening of the steam valve is quickly adjusted from the first opening to the second opening within the first time period, thereby ensuring the heating efficiency of the heat exchanger and further ensuring the startup efficiency of the steel pickling equipment.

[0117] When the first temperature is lower than the first temperature threshold, it indicates that the temperature of the output pipeline is too low to withstand the rapid heating of the heat exchanger, and the opening of the steam valve needs to be adjusted from the first opening to the second opening within a second time period, wherein the second time period is greater than the first time period.

[0118] Exemplarily, the second duration and the first duration may be preset durations.

[0119] It should be noted that, when the first temperature is greater than the first temperature threshold, the opening of the steam valve is slowly adjusted from the first opening to the second opening, limiting the temperature variation of the output pipeline, avoiding damage to the output pipeline, and improving the safety of the pickling solution during the heating process.
