Description

Technical Field

[0001] This invention relates to the field of component control technology, and in particular to an acetylene output control method, apparatus and equipment. Background Technology

[0002] In the storage and transportation of acetylene gas, it is generally dissolved in organic solvents such as acetone. However, acetone is a volatile organic solvent with a boiling point of 56.6°C. During the acetylene gas output process, the acetone solvent evaporates along with the acetylene gas, forming an acetylene / acetone mixture, which significantly affects the purity of the acetylene gas.

[0003] During acetylene output, changes in pressure and ambient temperature during acetylene release alter the loss ratio of acetone to acetylene, leading to variations in the acetone / acetylene mixture. Therefore, controlling the stable output of acetone / acetylene from the acetylene dissolution unit is crucial for ensuring the stable operation of subsequent acetylene utilization processes.

[0058] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0060] Example 1

[0061] Figure 1This is a flowchart of an acetylene output control method provided in Embodiment 1 of the present invention. It is applicable to situations requiring stable acetylene output. This method can be executed by the acetylene output control device provided in this embodiment of the invention, which can be implemented in hardware and / or software. For example... Figure 1 As shown, the method includes:

[0062] S101. Obtain the initial mass of the acetylene storage device.

[0063] The acetylene stored in the acetylene storage device is dissolved in acetone. The acetylene storage device includes cylinders, etc. The initial mass of the acetylene storage device can be obtained by weighing the device at room temperature before discharging acetylene gas. The room temperature condition can be set according to the actual ambient temperature, and can be within the range of 15℃-30℃.

[0064] In an optional embodiment, the initial mass of the acetylene storage device can also be determined through a combination of theoretical and practical methods. That is, the initial mass includes the acetylene filling quantity and the initial tare weight of the acetylene storage device. The initial tare weight of the acetylene storage device includes the weight of the storage device itself, the weight of the packing material, the weight of the accessories, and the acetone filling quantity. These data can be specified by the acetylene gas manufacturer on the acetylene storage device. The accessories include valves and protective covers. The packing material includes substances such as calcium silicate. Because acetylene gas is unstable and prone to polymerization reactions that can cause explosions, the packing material has a certain porosity, which reduces the collision rate between acetylene gases during filling, improving safety and uniformity of acetylene gas output.

[0065] S102. Timely collect real-time information when the acetylene storage device outputs acetylene.

[0066] The real-time information includes real-time mass, real-time temperature, and real-time pressure.

[0067] Specifically, during acetylene output, acetone in the acetylene storage device will be lost due to factors such as pressure or temperature changes. The real-time mass is the initial mass minus the acetylene output and acetone loss, resulting in the remaining mass of the acetylene storage device. Real-time temperature refers to the internal temperature of the acetylene storage device measured in real-time by a temperature detection device during acetylene output. Real-time pressure refers to the internal pressure of the acetylene storage device measured in real-time by a pressure detection device during acetylene output. Real-time information can be acquired periodically, thereby reducing the operating time of the real-time information acquisition device and extending its service life.

[0068] S103. Based on the initial mass, real-time mass, real-time temperature, and real-time pressure, determine the current loss mass ratio of acetone to acetylene when the acetylene storage device outputs acetylene.

[0069] Specifically, acetone has different saturated vapor pressures under different pressures and temperatures. During the acetylene output process, the saturated vapor pressure of acetone can be determined based on real-time temperature and pressure, and the amount of acetone loss can be determined by combining this with the obtained real-time mass. Since the tare weight and packing quantity of the acetylene storage device do not change with the output of acetylene, the acetylene output can be determined by the difference between the initial mass and the acetone loss. The ratio of the acetone loss to the acetylene output can then be used as the current mass ratio of acetone to acetylene loss during acetylene output.

[0070] S104. Determine whether the current loss quality ratio is greater than the preset loss quality ratio; if so, execute S105.

[0071] The preset loss mass ratio can be set according to actual needs. When the current loss mass ratio is greater than the preset loss mass ratio, the purity of acetylene may be low due to the large proportion of acetone, which may affect the stable operation of subsequent acetylene use processes.

[0072] S105. Determine the set temperature based on the preset loss mass ratio, initial mass, real-time mass, and real-time pressure.

[0073] Specifically, if the current loss ratio of acetone to acetylene is greater than the preset loss ratio, it indicates that the proportion of acetone loss is high, and the proportion of acetone loss needs to be reduced so that the ratio of the two is less than or equal to the preset loss ratio, thereby improving the purity of acetylene. Treating the set loss amount of acetone as an unknown quantity, the set loss amount of acetone can be calculated backwards based on the current acetylene output and the preset loss ratio. Based on the saturated vapor pressure of acetone under different pressure and temperature conditions, the set temperature is calculated according to the real-time mass and real-time pressure.

[0074] S106. Control the current temperature of the acetylene storage device according to the set temperature.

[0075] Specifically, based on the determined set temperature, the current temperature of the acetylene storage device is controlled to the set temperature through a cooling device, etc. At this set temperature, the loss of acetone can be equal to or less than the set loss, thereby achieving the purpose of controlling the loss of acetone, so that the ratio of the loss of acetone to the output of acetylene is less than or equal to the preset loss mass ratio, accurately controlling the output ratio of acetone and acetylene, and achieving a stable supply of acetylene.

[0076] The technical solution provided by this invention obtains the initial mass of the acetylene storage device, periodically collects real-time information on the output of acetylene from the acetylene storage device, and determines the current loss mass ratio of acetone to acetylene when the acetylene storage device outputs acetylene based on the initial mass, real-time mass, real-time temperature, and real-time pressure in the real-time information. When the current loss mass ratio is greater than a preset loss mass ratio, a set temperature is determined based on the preset loss mass ratio, initial mass, real-time mass, and real-time pressure, and the current temperature of the acetylene storage device is controlled to be the set temperature, so as to control the current loss mass ratio not to exceed the preset loss mass ratio, thereby achieving precise control of the loss of acetone and acetylene and improving the output stability of acetylene.

[0077] Example 2

[0078] Figure 2 This is a flowchart of an acetylene output control method provided in Embodiment 2 of the present invention. The method further details how the current loss mass ratio of acetone to acetylene is determined when the acetylene storage device outputs acetylene based on the initial mass, real-time mass, real-time temperature, and real-time pressure. Figure 2 As shown, the method includes:

[0079] S201. Obtain the initial mass of the acetylene storage device.

[0080] S202. Timely collect real-time information on the acetylene output from the acetylene storage device.

[0081] S203. Based on the initial mass and real-time mass, determine the current total amount of acetone-acetylene volatilization when the acetylene storage device outputs acetylene.

[0082] Specifically, during acetylene output, due to factors such as pressure or temperature changes in the acetylene storage device, a certain amount of acetone in the storage device will evaporate along with the acetylene output. Since only acetylene and a portion of acetone are output during acetylene output, the total acetone-acetylene evaporation at the time of output can be obtained by subtracting the initial mass from the current mass.

[0083] S204. Determine the current acetone loss when the acetylene storage device outputs acetylene based on real-time mass, real-time temperature, and real-time pressure.

[0084] Specifically, the current acetone loss is determined by the real-time mass, real-time temperature, and real-time pressure. Any change in any of these parameters will cause a change in the current acetone loss.

[0085] In an optional embodiment, determining the current acetone loss when the acetylene storage device outputs acetylene based on real-time mass, real-time temperature, and real-time pressure specifically includes: obtaining an acetone loss calculation model; and determining the current acetone loss when the acetylene storage device outputs acetylene based on the acetone loss calculation model according to the real-time mass, real-time temperature, and real-time pressure.

[0086] The calculation model for acetone loss can be expressed as a formula or a data table, and this embodiment of the invention does not impose specific limitations on it. If the calculation model for acetone loss is a formula, the current acetylene loss can be obtained by substituting the real-time mass, real-time temperature, and real-time pressure into the formula; if the calculation model for acetone loss is a data table, the current acetone loss can be obtained by corresponding data in the data table for the real-time mass, real-time temperature, and real-time pressure.

[0087] Optionally, the acetone loss calculation model can be: M = (m 初 -m)+a(T,P)·(P+1), where M is the amount of acetone lost, m 初 Let m be the initial mass of the acetylene storage device, T be the real-time weight of the acetylene storage device, P be the real-time temperature of the acetylene storage device, and a(T,P) be the coefficients related to the real-time temperature and real-time pressure.

[0088] Specifically, the acetone loss M is determined by the initial mass m of the acetylene storage device. 初 The acetone loss is determined by the real-time mass m, real-time temperature T, and real-time pressure P. A change in any of these parameters will affect the amount of acetone lost. The coefficient a(T,P) is related to the porosity of the acetylene storage device's packing material, the volume of the acetylene storage device itself, the density within the acetylene storage device, and the solubility of acetylene in acetone. Since the porosity of the acetylene storage device's packing material and the volume of the acetylene storage device itself remain constant after the acetylene storage device leaves the factory, and the density within the acetylene storage device and the solubility of acetylene in acetone are related to the real-time temperature T and real-time pressure P of the acetylene storage device, a(T,P) can be understood as a coefficient jointly determined by the real-time temperature and real-time pressure. This coefficient can be obtained by looking up a table.

[0089] S205. Determine the current acetylene volatilization amount when the acetylene storage device outputs acetylene based on the total acetone-acetylene volatilization amount and the acetone loss amount.

[0090] Specifically, the difference between the total acetone-acetylene volatilization and the acetone loss is obtained, and this difference can be used as the current acetylene volatilization amount.

[0091] S206. Determine the current mass ratio of acetone to acetylene loss based on the current acetone loss and the current acetylene volatilization.

[0092] The ratio of the current acetone loss to the current acetylene volatilization is used as the current loss mass ratio of acetone to acetylene.

[0093] S207. Determine whether the current loss quality ratio is greater than the preset loss quality ratio; if so, execute S208.

[0094] S208. Determine the set temperature based on the preset loss mass ratio, initial mass, real-time mass, and real-time pressure.

[0095] S209. Control the current temperature of the acetylene storage device according to the set temperature.

[0096] The technical solution of this invention first determines the current total acetone-acetylene volatilization when the acetylene storage device outputs acetylene based on the difference between the initial mass and the real-time mass; then, based on the real-time mass, real-time temperature, and real-time pressure, calculates and determines the current acetone loss when the acetylene storage device outputs acetylene; next, based on the difference between the total acetone-acetylene volatilization and the acetone loss, determines the current acetylene volatilization amount when the acetylene storage device outputs acetylene; finally, based on the ratio of the current acetone loss to the current acetylene volatilization amount, determines the current loss mass ratio of acetone to acetylene.

[0097] Real-time Example 3

[0098] Figure 3 This is a flowchart of an acetylene output control method provided in Embodiment 3 of the present invention. The method specifically describes how to determine the set temperature based on a preset loss mass ratio, initial mass, real-time mass, and real-time pressure. For example... Figure 3 As shown, the method includes:

[0099] S301. Obtain the initial mass of the acetylene storage device.

[0100] S302. Timely collect real-time information when the acetylene storage device outputs acetylene.

[0101] S303. Based on the initial mass, real-time mass, real-time temperature, and real-time pressure, determine the current loss mass ratio of acetone to acetylene when the acetylene storage device outputs acetylene.

[0102] S304. Determine whether the current loss quality ratio is greater than the preset loss quality ratio; if so, execute S305.

[0103] S305. Based on the initial mass and real-time mass, determine the current total amount of acetone-acetylene volatilization when the acetylene storage device outputs acetylene.

[0104] The total amount of acetone-acetylene volatilized at the time of acetylene output is obtained by subtracting the real-time mass from the initial mass.

[0105] S306. Determine the current acetone loss when the acetylene storage device outputs acetylene based on real-time mass, real-time temperature, and real-time pressure.

[0106] Specifically, the current acetone loss is determined by the real-time mass, real-time temperature, and real-time pressure. A change in any of these parameters will alter the current acetone loss. It is understood that the relationship between the current acetone loss and the real-time mass, temperature, and pressure can be set according to actual needs, and this embodiment of the invention does not impose specific limitations on this.

[0107] In an optional embodiment, the acetone loss can satisfy the acetone loss calculation model with respect to real-time mass, real-time temperature, and real-time pressure: M = (m 初 -m)+a(T,P)·(P+1), where M is the amount of acetone lost, m 初 Let m be the initial mass of the acetylene storage device, T be the real-time mass of the acetylene storage device, P be the real-time temperature of the acetylene storage device, and a(T,P) be a coefficient related to the real-time temperature and the real-time pressure.

[0108] S307. Determine the current acetylene volatilization amount when the acetylene storage device outputs acetylene based on the total acetone-acetylene volatilization amount and the acetone loss amount.

[0109] The difference between the total acetone-acetylene volatilization and the acetone loss is taken as the current acetylene volatilization.

[0110] S308. Determine the set loss amount of acetone based on the preset loss mass ratio and the current acetylene volatilization amount.

[0111] The product of the preset loss mass ratio and the current acetylene volatilization amount is the preset loss amount of acetone.

[0112] S309. Determine the set temperature of the acetylene storage device based on the set loss amount, real-time mass, and real-time pressure.

[0113] Specifically, since the amount of acetone loss is related to the real-time mass, real-time temperature, and real-time pressure, the set temperature can be determined based on the set amount of acetone loss, real-time mass, and real-time pressure.

[0114] In an optional embodiment, since the acetone loss can satisfy the acetone loss calculation model with respect to real-time mass, real-time temperature, and real-time pressure: M = (m 皮 -m)+a(T,P)·(P+1), therefore, by substituting the set loss amount of acetone, the real-time mass and the real-time pressure into the acetone loss calculation model, the corresponding temperature can be calculated, which is the set temperature.

[0115] S310. Control the current temperature of the acetylene storage device according to the set temperature.

[0116] The technical solution of this invention determines the current total acetone-acetylene volatilization when the acetylene storage device outputs acetylene by using the difference between the initial mass and the real-time mass. It then determines the current acetone loss when the acetylene storage device outputs acetylene by using the relationship between the real-time mass, real-time temperature, real-time pressure, and the current acetone loss. Finally, it determines the current acetylene volatilization amount when the acetylene storage device outputs acetylene by using the difference between the total acetone-acetylene volatilization and the acetone loss. Next, it determines the set loss amount of acetone based on the product of the preset loss mass ratio and the current acetylene volatilization amount. Furthermore, it determines the set temperature of the acetylene storage device based on the relationship between the real-time mass, real-time temperature, real-time pressure, and the current acetone loss amount, using the set loss amount, real-time mass, and real-time pressure. This set temperature is then used to control the real-time temperature of the acetylene storage device, thereby precisely controlling the acetone loss.

[0117] Example 4

[0118] Figure 4 The flowchart of an acetylene output control method provided in Embodiment 4 of the present invention is as follows: Figure 4 As shown, the method includes:

[0119] S401. Obtain the initial mass of the acetylene storage device.

[0120] S402. Timely collect real-time information when the acetylene storage device outputs acetylene.

[0121] S403. Based on the initial mass, real-time mass, real-time temperature, and real-time pressure, determine the current loss mass ratio of acetone to acetylene when the acetylene storage device outputs acetylene.

[0122] S404. Determine whether the current loss quality ratio is greater than the preset loss quality ratio; if so, execute S405.

[0123] S405. Determine the set temperature based on the preset loss mass ratio, initial mass, real-time mass, and real-time pressure.

[0124] S406. Determine whether the set temperature is within the preset temperature range; if yes, proceed to S407; if no, proceed to S408.

[0125] The preset temperature range can be set according to actual needs, and this embodiment of the invention does not impose specific limitations on it. For example, the preset temperature range is 20℃-25℃.

[0126] Specifically, if the set temperature is within the preset temperature range, it means that the current temperature of the acetylene storage device can be controlled to the set temperature by a cooling device or similar means. If the set temperature exceeds the preset temperature range, it means that the device or equipment that cannot control the current temperature of the acetylene storage device by a cooling device or similar means cannot control the current temperature to the set temperature.

[0127] S407. Control the current temperature of the acetylene storage device according to the set temperature.

[0128] S408, Issue an alarm notification.

[0129] Alarm reminders can be provided via buzzer, voice, or light.

[0130] Specifically, when the set temperature exceeds the preset temperature range, an alarm will be triggered to remind maintenance personnel to perform relevant operations, such as shutting down the acetylene output channel and replacing the cylinder.

[0131] The technical solution of this invention determines whether the set temperature is within the preset temperature range. If so, an alarm is triggered to remind maintenance personnel to perform relevant operations, preventing the acetylene gas from containing a high proportion of acetone when the current storage device outputs acetylene, thus reducing the output ratio and stability of the acetylene gas.
