BRIEF DESCRIPTION OF THE DRAWINGS

[0052] Figure 1 The present invention shows a flow chart of an automatic system for controlling copper liquid by precise reduction using natural gas. DETAILED DESCRIPTION

[0053] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0054] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0055] Figure 1 The present invention shows a flow chart of an automatic system for controlling copper liquid by precise reduction using natural gas.

[0056] like Figure 1As shown, the present invention discloses an automatic system for controlling copper liquid by accurate reduction using natural gas, comprising:

[0057] Data collection module, data processing module, gas input module, buffer module, gas output module and gas detection and emission module;

[0058] The data collection module is used to collect data during the natural gas reduction control of copper liquid;

[0059] The data processing module is used to process the collected data and generate corresponding control information;

[0060] The gas input module is used to input gas;

[0061] The buffer module is used to process the input and output gases to improve the efficiency and safety of reducing the copper liquid;

[0062] The gas output module is used to output gas;

[0063] The gas detection and discharge module is used to detect and discharge the output gas.

[0064] According to an embodiment of the present invention, the data collection module includes a variety of testing devices or sensors and other equipment that can collect data, such as an oxygen measurement tester and a temperature sensor. The oxygen content in the copper liquid is tested by the oxygen measurement tester, and the temperature value of the copper liquid and the temperature value of the input gas are detected by the temperature sensor. The collected data is then sent to the data processing module for corresponding data processing, and corresponding control information is generated, such as generating corresponding natural gas control information based on the collected natural gas data, generating corresponding copper liquid temperature control information based on the collected copper liquid temperature data, etc.

[0065] According to an embodiment of the present invention, the data processing module includes: a natural gas processing unit, a temperature processing unit and an oxygen-containing control unit;

[0066] The natural gas processing unit is used to process the collected natural gas data and generate natural gas control information;

[0067] The temperature processing unit is used to process the collected copper liquid temperature data and generate copper liquid temperature control information;

[0068] The oxygen content control unit is used to set the oxygen content parameter in the copper liquid. When the oxygen content in the copper liquid is less than or equal to the oxygen content parameter, a prompt message for closing the natural gas input is generated.

[0069] It should be noted that each unit in the data processing module sets a corresponding threshold parameter. For example, the oxygen content parameter in the copper liquid is set in the oxygen content control unit, and the oxygen content in the collected copper liquid is determined. If the oxygen content in the copper liquid is less than or equal to the oxygen content parameter, it means that the oxygen content in the corresponding copper liquid is qualified, and a prompt message for closing the natural gas input is generated, and the prompt message for closing the natural gas input is sent to the gas input module to close the gas delivery; further, the temperature processing unit is also used to determine the temperature value of the input or output gas. If the temperature value of the input or output gas is greater than a preset gas temperature threshold, temperature control information for reducing the input or output gas is generated.

[0070] According to an embodiment of the present invention, the step of generating natural gas control information specifically includes:

[0071] According to the collected natural gas data, the input natural gas concentration value is obtained;

[0072] Determine whether the input natural gas concentration value is within the preset concentration range, if so, the corresponding input natural gas concentration value is normal;

[0073] If not, determine whether the input natural gas concentration value is greater than the maximum value in the preset concentration range, and if so, generate information on reducing the natural gas concentration value; if not, generate information on increasing the natural gas concentration value;

[0074] The natural gas control information includes information on reducing the natural gas concentration value and information on increasing the natural gas concentration value.

[0075] It should be noted that the input gas is a mixed gas mainly composed of natural gas and supplemented by inert gas. Natural gas is a flammable gas, and the safety performance is improved by mixing with inert gas. When information on reducing the natural gas concentration value is generated, the natural gas concentration value is reduced by adding inert gas. When information on increasing the natural gas concentration value is generated, the natural gas concentration value is increased by directly adding natural gas.

[0076] According to an embodiment of the present invention, the step of generating the copper liquid temperature control information specifically includes:

[0077] According to the collected temperature data of the copper liquid, the temperature value of the copper liquid is obtained;

[0078] Determine whether the temperature value of the copper liquid is within a preset temperature value range, and if so, the temperature value of the corresponding copper liquid is normal;

[0079] If not, determine whether the temperature value of the copper liquid is greater than the maximum value in the preset temperature value range, and if so, generate information on reducing the temperature value of the copper liquid; if not, generate information on increasing the temperature value of the copper liquid;

[0080] The copper liquid temperature control information includes information on lowering the temperature value of the copper liquid and information on increasing the temperature value of the copper liquid.

[0081] It should be noted that reasonable control of the temperature of the copper liquid can improve the reduction efficiency of the copper liquid.

[0082] According to an embodiment of the present invention, the data processing module is further used to:

[0083] Based on the preset spectral detection equipment, the content ratio of the oxygen element in the input gas and the content ratio of the oxygen element in the output gas are obtained;

[0084] The oxygen content ratio in the output gas is subtracted from the oxygen content ratio in the input gas to obtain the oxygen content ratio difference;

[0085] If the difference in the oxygen content ratio is less than the preset content ratio threshold, information for reducing the gas input flow rate is generated;

[0086] The reduced gas input flow rate information is sent to the gas input module for adjustment.

[0087] It should be noted that due to the reduction reaction before and after the natural gas passes through the copper liquid, the content ratio of the oxygen element in the output gas will increase. When the difference in the content ratio of the oxygen element is less than the preset content ratio threshold, it means that the reduction reaction of the natural gas on the copper liquid is not thorough enough. Therefore, by adjusting the input gas flow rate and increasing the contact time between the natural gas and the copper liquid, the reduction efficiency of the natural gas and the copper liquid can be improved.

[0088] According to an embodiment of the present invention, the buffer module comprises: a buffer unit, a compression unit and a cooling unit;

[0089] The buffer unit is used to buffer the input gas and the output gas;

[0090] The compression unit is used to pressurize the input gas and relieve the pressure of the output gas;

[0091] The cooling unit is used to cool the input or output gas.

[0092] It should be noted that since natural gas is a flammable and explosive gas, when the input gas contains natural gas as a reducing agent, the input or output gas needs to be buffered to improve safety in use; in addition, the input gas is increased by a compression unit to improve the reduction efficiency of natural gas and copper liquid in the input gas, and then the output gas is depressurized to improve safety in use; the cooling unit receives temperature control information for lowering the input or output gas generated by the temperature processing unit, and controls the temperature of the input or output gas.

[0093] According to an embodiment of the present invention, the gas input module is further used for:

[0094] Based on the preset spectrum detection equipment, obtain the elements in the input gas;

[0095] Compare and analyze the elements in the input gas with the preset elements. If the elements in the input gas are the same as the preset elements, extract the corresponding identical elements and obtain the content ratio of the corresponding identical elements in the input gas elements.

[0096] Multiply the content ratio of the same element in the input gas element by the influence weight coefficient corresponding to the same element to obtain the influence value corresponding to the same element;

[0097] Add up the impact values ​​of all the same elements to get the total impact value;

[0098] If the total impact value is greater than the preset impact threshold, the input gas warning message is triggered.

[0099] According to an embodiment of the present invention, after triggering the input of gas warning information, the method further includes:

[0100] Sort all identical elements according to their corresponding influence values, and obtain the identical element with the largest influence value;

[0101] Matching corresponding filtering devices according to the same elements, and inputting the gas into the filtering device corresponding to the value for filtering, thereby obtaining filtered gas;

[0102] Obtaining elements in the filtered gas, determining the same elements in the filtered gas, and calculating the influence values ​​of the same elements in the filtered gas;

[0103] If the cumulative value of the influence values ​​of the same elements in the gas after filtration is still greater than the preset influence threshold, the same elements in the gas after filtration are sorted according to the corresponding influence values ​​to obtain the same elements with the maximum influence values ​​in the gas after filtration, and the same elements with the maximum influence values ​​in the gas after filtration are filtered until the cumulative value of the influence values ​​of the same elements in the gas after filtration is less than or equal to the preset influence threshold.

[0104] It should be noted that the preset element is an element that affects the reduction of oxygen in the copper liquid by natural gas, such as oxygen. When the input gas contains too much oxygen, the oxygen in the input gas will also be introduced into the copper liquid; after each filtration of the input gas, the filtered gas is tested to improve the reduction performance and safety performance of the input gas, until the corresponding input gas meets the requirements before it can undergo a reduction reaction with the copper liquid.

[0105] According to an embodiment of the present invention, the gas detection and emission module comprises: a gas detection unit and an emission unit;

[0106] The gas detection unit is used to detect the output gas, determine the element composition and corresponding ratio in the output gas, and generate gas emission information when a preset marked element composition exists and the corresponding ratio is less than a preset ratio threshold;

[0107] The emission unit emits the output gas based on the gas emission information.

[0108] It should be noted that the preset marker elements are oxidizing elements that are polluting to the air, such as nitrogen, sulfur, etc. Nitrogen and oxygen may generate nitric oxide, which is a toxic gas and is difficult to dissolve in water. When the marker element component ratio is less than the preset ratio threshold, it means that the polluting elements account for a small proportion in the output gas and can be discharged; if the marker element component ratio is greater than or equal to the preset ratio threshold, it means that the polluting elements account for a large proportion in the output gas and cannot be discharged directly. In addition, when the output gas is discharged, the output gas needs to be completely burned.

[0109] According to an embodiment of the present invention, the gas detection and emission module is further used for:

[0110] The content ratio of natural gas in the output gas is determined according to the element composition and corresponding proportion in the output gas; if the content ratio of natural gas in the output gas is greater than the preset natural gas content ratio threshold, the corresponding output gas will be recycled; if the content ratio of natural gas in the output gas is less than or equal to the preset natural gas content ratio threshold, gas emission information is generated.

[0111] It should be noted that the entire natural gas precise reduction control copper liquid automatic system is in a sealed state. The gas output module collects and detects the output gas. If the natural gas content ratio in the output gas is greater than the preset natural gas content ratio threshold, the output gas will be transported to the gas input module for recycling.
