[0042] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0043] The following describes the industrial coating reaction gas setting method, device, electronic device and storage medium of the embodiment of the present application with reference to the accompanying drawings. In view of the problem mentioned in the above background technology that the reaction gas residual amount is different, resulting in unstable reaction gas output or lack of reaction gas, resulting in poor coating stability and low coating accuracy, the present application provides an industrial coating reaction gas setting method, in which the gas demand of the reactor, the temperature and pressure of each gas cylinder are obtained, and the gas residual amount of each gas cylinder is calculated according to the temperature and pressure of each gas cylinder, and the gas flow of each gas cylinder is determined according to the gas demand and the gas residual amount of each gas cylinder, so as to adjust the gas regulating valve of each gas cylinder according to the gas flow of each gas cylinder. In this way, the problem of poor coating stability and low coating accuracy caused by unstable reaction gas output or lack of reaction gas due to different reaction gas residual amounts is solved, and the residual amount of reaction gas can be accurately monitored, and when the residual amount is low, the replaceable reaction gas can be switched in time, the reaction gas can be output stably, and the gas environment of industrial coating can be ensured.

[0044] Specifically, Figure 1 A schematic flow chart of a method for providing reaction gas for industrial coating provided in an embodiment of the present application.

[0045] like Figure 1 As shown, the industrial coating reaction gas setting method includes the following steps:

[0046] In step S101 , the gas demand of the reactor, the temperature and pressure of each gas cylinder are obtained.

[0047] It is understandable that during the coating process, different coating requirements require the participation of different reaction gases. The embodiment of the present application can obtain the gas demand of the reactor and obtain the temperature and pressure of each reaction gas cylinder through monitoring equipment such as sensors.

[0048] In step S102, the remaining gas amount of each gas cylinder is calculated according to the temperature and pressure of each gas cylinder, and the gas flow of each gas cylinder is determined according to the gas demand and the remaining gas amount of each gas cylinder, so as to adjust the gas regulating valve of each gas cylinder according to the gas flow of each gas cylinder.

[0049] Here, the calculation of the remaining gas amount of each gas cylinder is explained below.

[0050] Specifically, the embodiment of the present application can calculate the remaining amount of gas in each gas cylinder according to the temperature and pressure of each gas cylinder. For example, according to the ideal gas state equation PV=nRT, it can be obtained that:

[0051]

[0052] Among them, P is the current cylinder pressure, V is the volume of the cylinder, n is the molar mass of the gas, R is the ideal gas constant, and T is the current temperature.

[0053] In actual implementation, especially at high pressures, the ideal gas state equation may not be accurate enough. In this case, it may be necessary to use a compressibility factor Z to correct the volume: PV = nZRT, where the compressibility factor ZZ is a dimensionless number that takes into account the actual interactions between gas molecules and the volume, which can be obtained from experimental data or thermodynamic tables.

[0054] Optionally, in some embodiments, before calculating the remaining amount of gas in each gas cylinder according to the temperature and pressure of each gas cylinder, it also includes: obtaining the initial pressure, initial temperature, current pressure and current temperature of each gas cylinder; calculating the number of moles of gas in each gas cylinder according to the initial pressure, initial temperature, current pressure and current temperature of each gas cylinder.

[0055] Specifically, for a given gas cylinder, the volume of the gas cylinder is fixed. The embodiment of the present application can determine the number of moles of gas in the initial state according to the initial pressure and initial temperature of each gas cylinder, determine the number of moles of gas in the final state by the current pressure and current temperature, and determine the remaining number of moles by the number of moles of gas in the initial state and the number of moles of gas in the final state.

[0056] For example, if the total volume of a gas cylinder is 40L, the initial pressure is 15MPa, the initial temperature is 20℃, the current pressure is 5MPa, and the current temperature is 20℃, then the initial and final moles of gas can be calculated as:

[0057] Initial state:

[0058] Final state:

[0059] Remaining molar number of gas Δn: Δn=n1-n2.

[0060] Then, use the remaining moles of gas to calculate the remaining amount in each cylinder.

[0061] Furthermore, in some embodiments, the gas flow rate of each gas cylinder is determined based on the gas demand and the remaining gas amount of each gas cylinder, including: determining the total gas flow rate based on the gas demand; if the remaining gas amount of any gas cylinder is lower than a first preset threshold, reducing the gas flow rate of the corresponding gas cylinder according to a first decreasing strategy, and determining a first increasing strategy based on the total gas flow rate and the first decreasing strategy; and increasing the gas flow rate of the replaceable gas cylinder according to the first increasing strategy.

[0062] The first preset threshold may be pre-set by a user, obtained through a limited number of experiments, or obtained through a limited number of computer simulations, and is not specifically limited here.

[0063] It is understandable that during the coating process, the functions of certain reaction gases are the same. For example, there are reaction gas A and alternative gas B for reaction gas A. When the remaining amount of gas A is small, in order to ensure stable gas output, the gas flow rate of alternative gas B can be increased and the output of gas A can be reduced.

[0064] Specifically, the total gas flow is determined according to the gas demand. If the remaining gas volume of any gas cylinder is lower than the first preset threshold, the first decreasing strategy can be used to reduce the gas flow of the corresponding gas cylinder. At the same time, the first increasing strategy is determined according to the total gas flow and the first decreasing strategy to increase the gas flow of the replaceable gas cylinder. This process can be achieved through an intelligent PID control algorithm to ensure accurate regulation of the flow rate.

[0065] For example, if the total demand is X liters / minute, and assuming that cylinders A and B take on flows of Xa and Xb respectively, the new flow distribution can be calculated as follows:

[0066] If the remaining amount of gas cylinder A is lower than the set threshold, reduce the flow rate of gas cylinder A to X'a = f(Xa), where f is a decreasing function to ensure that X'a <Xa;

[0067] At the same time, the flow rate of gas cylinder B is increased to X'b=Xb+(Xa-X'a) to compensate for the reduced flow rate of gas cylinder A, ensuring that the total flow rate X=X'a+X'b remains unchanged.

[0068] Optionally, in some embodiments, after determining the gas flow of each gas cylinder according to the gas demand and the remaining gas amount of each gas cylinder, it also includes: if the remaining gas amount of any gas cylinder is lower than a second preset threshold, switching the corresponding gas cylinder to a backup gas cylinder.

[0069] The second preset threshold may be pre-set by a user, obtained through a limited number of experiments, or obtained through a limited number of computer simulations, and is not specifically limited here.

[0070] Specifically, if the remaining gas amount in any gas cylinder is lower than a second preset threshold, the corresponding gas cylinder can be switched to a backup gas cylinder. This can be achieved through an automatic switching system, which automatically switches the gas supply from the exhausted gas source to the backup gas source when it detects that the gas pressure is lower than the conversion pressure, reducing the burden of manual switching and downtime.

[0071] Optionally, in some embodiments, after determining the gas flow of each gas cylinder according to the gas demand and the remaining gas amount of each gas cylinder, it also includes: if the remaining gas amount of any gas cylinder is lower than a second preset threshold, generating a replacement reminder instruction to perform a replacement reminder according to the replacement reminder instruction.

[0072] Specifically, if the remaining gas amount in any gas cylinder is lower than the second preset threshold, there may be a situation where there is no backup gas cylinder. The embodiment of the present application can replace the reminder instruction to provide a replacement reminder according to the replacement reminder instruction. This method can be achieved through a monitoring system. When the pressure or temperature of the gas cylinder exceeds the normal range, the system will issue a reminder so as to promptly remind relevant personnel to handle it.

[0073] According to the industrial coating reaction gas setting method proposed in the embodiment of the present application, the gas demand of the reactor, the temperature and pressure of each gas cylinder are obtained, and the remaining gas amount of each gas cylinder is calculated according to the temperature and pressure of each gas cylinder. The gas flow of each gas cylinder is determined according to the gas demand and the remaining gas amount of each gas cylinder, so as to adjust the gas regulating valve of each gas cylinder according to the gas flow of each gas cylinder. In this way, the problem of unstable reaction gas output due to different reaction gas remaining amounts or poor coating stability and low coating accuracy caused by lack of reaction gas is solved, the remaining amount of reaction gas can be accurately monitored, and when the remaining amount is low, the replaceable reaction gas can be switched in time to stably output the reaction gas, thereby ensuring the gas environment for industrial coating.

[0079] Optionally, in some embodiments, the adjustment module 200 includes: a first determination unit, a second determination unit and an adjustment unit.

[0080] Wherein, the first determination unit is used to determine the total gas flow rate according to the gas demand.

[0083] Optionally, in some embodiments, before calculating the remaining amount of gas in each gas cylinder according to the temperature and pressure of each gas cylinder, the adjustment module 200 further includes: an acquisition unit and a calculation unit.

[0084] The acquisition unit is used to obtain the initial pressure, initial temperature, current pressure and current temperature of each gas cylinder.

[0085] The calculation unit is used to calculate the mole number of gas in each gas cylinder according to the initial pressure, initial temperature, current pressure and current temperature of each gas cylinder.

[0086] Optionally, in some embodiments, after determining the gas flow rate of each gas cylinder according to the gas demand and the remaining gas amount of each gas cylinder, the regulating module 200 further includes: a switching unit.

[0087] The switching unit is used to switch the corresponding gas cylinder to a backup gas cylinder when the remaining gas amount in any gas cylinder is lower than a second preset threshold.

[0088] Optionally, in some embodiments, after determining the gas flow rate of each gas cylinder according to the gas demand and the remaining gas amount of each gas cylinder, the regulating module 200 further includes: a reminder unit.
