Description

Technical Field

[0001] The utility model relates to the technical field of monitoring and alarming of liquefied gas, in particular to a safety prevention and control device for a liquefied gas digital factory. Background Art

[0002] Digital Factory (DF) is an advanced manufacturing model that uses digital technology, big data, artificial intelligence, the Internet of Things and other advanced technologies to connect production lines and production equipment to achieve high efficiency, automation, intelligence and adaptability.

[0003] The liquefied gas digital factory uses advanced technologies such as digital technology, big data, artificial intelligence and the Internet of Things to connect the liquefied gas processing production line and production equipment, making the production and processing of liquefied gas efficient, automated and intelligent.

[0004] The liquefied gas digital factory is equipped with a signal receiving center and an industrial computer for controlling the processing production line and production equipment. Through the cooperation between the signal receiving center and the industrial computer, the overall control of the processing production line and production equipment is achieved.

[0005] Liquefied gas is mainly composed of hydrocarbons, and its main components are propane, butane and other alkanes. Since liquefied gas has a very high calorific value and contains hydrocarbons with a low ignition point, liquefied petroleum gas is explosive and flammable. Once a leak occurs, it is very likely to cause a safety accident, posing a great threat to the safety of the factory.

[0006] In order to avoid adverse consequences caused by leakage of liquefied gas during production and processing, alarms are usually installed in factories to monitor leaked liquefied gas. For example, patent document CN212229789U discloses a new type of liquefied gas leakage alarm device. Once the liquefied gas leakage alarm device detects leakage of liquefied gas, it alerts the workers in the factory by sounding an alarm to achieve the purpose of safety prevention and control.

[0007] However, due to the different densities of liquefied gas and air, the leaked liquefied gas and air will be in different altitude layers. When the alarm and the leaked liquefied gas are in different altitude layers, the leaked liquefied gas is difficult to be effectively monitored by the alarm.

[0008] Based on this, a liquefied gas digital factory safety control equipment is proposed. Summary of the invention

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0044] Embodiment 1

[0045] The liquefied gas digital factory is equipped with a signal receiving center and an industrial computer for controlling the processing production line and production equipment. Through the cooperation between the signal receiving center and the industrial computer, the overall control of the processing production line and production equipment is achieved.

[0046] Once liquefied gas leaks, it can easily cause a safety accident, posing a great threat to the safety of the factory.

[0047] In order to avoid adverse consequences caused by leakage of liquefied gas during production and processing, alarms are usually installed in factories to monitor leaked liquefied gas. For example, patent document CN212229789U discloses a new type of liquefied gas leakage alarm device. Once the liquefied gas leakage alarm device detects leakage of liquefied gas, it alerts the workers in the factory by sounding an alarm to achieve the purpose of safety prevention and control.

[0048] However, due to the different densities of liquefied gas and air, the leaked liquefied gas and air will be in different altitude layers. When the alarm and the leaked liquefied gas are in different altitude layers, the leaked liquefied gas is difficult to be effectively monitored by the alarm.

[0049] Based on this, in order to solve the above technical problems, the inventors have adopted the following technical solutions, which are as follows:

[0050] like Figure 1-8 As shown, the utility model provides a technical solution:

[0051] A liquefied gas digital factory safety control equipment, comprising:

[0052] The cylindrical shell 10 is arranged on the top of the plant building of the liquefied gas digital plant;

[0053] A gas leakage detection structure 20, which is installed below the inner cavity of the cylindrical shell 10;

[0054] The gas leakage detection structure 20 includes an annular housing 201, a gas sensor 202 is installed on the lower surface of the annular housing 201, the model of the gas sensor 202 is MQ-S10 S5, a controller 203 is installed on the upper surface of the annular housing 201, the gas sensor 202 is electrically connected to the controller 203 through a wire, and a plurality of buzzer alarms 204 are fixedly installed on the bottom edge of the annular housing 201, and each buzzer alarm 204 is electrically connected to the controller 203 through a wire after being connected in series with each other;

[0055] Wherein, a plurality of buzzer alarms 204 are evenly distributed on the edge of the lower surface of the annular housing 201;

[0056] The controller 203 can be connected to the signal receiving center in the liquefied gas digital factory for communication; and

[0057] An air intake structure 30, which is installed above the inner cavity of the cylindrical shell 10;

[0058] The air intake structure 30 includes a motor 301, on the output shaft of which a wind wheel 302 is fixedly mounted. The motor 301 can drive the wind wheel 302 to rotate through its output shaft. When the wind wheel 302 rotates, Figure 7 As shown, the inner cavity of the cylindrical shell 10 can form an air suction zone, and the inhaled air can flow from the bottom opening of the cylindrical shell 10 from bottom to top, and flow out from the top opening of the cylindrical shell 10. Once a liquefied gas leak occurs in the liquefied gas processing production line in the liquefied gas digital factory, the leaked liquefied gas can be sucked into the inner cavity of the cylindrical shell 10 by the air suction zone, and the liquefied gas sucked into the inner cavity of the cylindrical shell 10 can be sensed by the gas sensor 202, thereby overcoming the technical problem that the leaked liquefied gas and air are in different altitude layers, and the alarm and the leaked liquefied gas are in different altitude layers, and the leaked liquefied gas is difficult to be effectively monitored by the alarm.

[0059] When the gas sensor 202 detects a leak of liquefied gas, it sends an electrical signal to the controller 203, and the controller 203 sends an electrical signal to multiple buzzer alarms 204, so that the multiple buzzer alarms 204 sound an alarm at the same time to remind the workers in the factory. At the same time, after the controller 203 is connected to the signal receiving center in the liquefied gas digital factory, the controller 203 can send a liquefied gas leakage signal to the signal receiving center, and the signal receiving center sends the signal to the industrial computer in the liquefied gas digital factory. The industrial computer controls the liquefied gas processing production line in the liquefied gas digital factory, so that the liquefied gas processing production line and production equipment are all stopped to achieve the purpose of safety prevention and control. When the liquefied gas processing production line no longer leaks liquefied gas and the gas sensor 202 cannot detect any leaking liquefied gas, the liquefied gas processing production line and production equipment are put into operation again through the cooperation between the controller 203, the signal receiving center and the industrial computer.

[0075] Each inverted L-shaped fixing frame 60 has a mounting hole 601 at one end of the top;

[0076] When the cylindrical shell 10 is at the top of the factory building of the liquefied gas digital factory, the top of each inverted L-shaped fixing bracket 60 is fitted with the top of the factory building, and after fitting, a screw is inserted and installed in each assembly hole 601, and each inverted L-shaped fixing bracket 60 is fastened to the top of the factory building by screws, so that the safety control equipment can be installed and fixed in the factory building of the liquefied gas digital factory.

[0077] In summary, the workflow of the utility model is:

[0078] like Figure 1-8As shown, the motor 301 can drive the wind wheel 302 to rotate through its output shaft. When the wind wheel 302 rotates, the inner cavity of the cylindrical shell 10 can form an air suction zone, and the sucked air can flow from the bottom opening of the cylindrical shell 10 from bottom to top, and flow out from the top opening of the cylindrical shell 10. Once a liquefied gas leak occurs in the liquefied gas processing production line in the liquefied gas digital factory, the leaked liquefied gas can be sucked into the inner cavity of the cylindrical shell 10 by the air suction zone, and the liquefied gas sucked into the inner cavity of the cylindrical shell 10 can be sensed by the gas sensor 202, thereby overcoming the technical problem that the leaked liquefied gas and air are in different altitude layers, and the leaked liquefied gas is difficult to be effectively monitored by the alarm when the alarm and the leaked liquefied gas are in different altitude layers.

[0079] When the gas sensor 202 detects a leak of liquefied gas, it sends an electrical signal to the controller 203, and the controller 203 sends an electrical signal to multiple buzzer alarms 204, so that the multiple buzzer alarms 204 sound an alarm at the same time to remind the workers in the factory. At the same time, after the controller 203 is connected to the signal receiving center in the liquefied gas digital factory, the controller 203 can send a liquefied gas leakage signal to the signal receiving center, and the signal receiving center sends the signal to the industrial computer in the liquefied gas digital factory. The industrial computer controls the liquefied gas processing production line in the liquefied gas digital factory, so that the liquefied gas processing production line and production equipment are all stopped to achieve the purpose of safety prevention and control. When the liquefied gas processing production line no longer leaks liquefied gas and the gas sensor 202 cannot detect any leaking liquefied gas, the liquefied gas processing production line and production equipment are put into operation again through the cooperation between the controller 203, the signal receiving center and the industrial computer.

[0080] When the cylindrical shell 10 is at the top of the factory building of the liquefied gas digital factory, the top of each inverted L-shaped fixing bracket 60 is fitted with the top of the factory building, and after fitting, a screw is inserted and installed in each assembly hole 601, and each inverted L-shaped fixing bracket 60 is fastened to the top of the factory building by screws, so that the safety control equipment can be installed and fixed in the factory building of the liquefied gas digital factory.

[0081] The above different embodiments can be combined, replaced and used in conjunction with each other.

[0082] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0083] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
