A gas supply system

Abstract

This utility model discloses an air supply system, which includes a main pipe and at least two sets of air supply units. Each air supply unit includes an air compressor and a dryer. A first branch pipe is provided connecting the air compressor and the dryer, and a second branch pipe is connected in parallel with the first branch pipe. The main pipe is sequentially connected to the air supply units. When one air compressor or dryer fails, the equipment in other air supply units can continue to work. If the air compressor of one air supply unit fails, the air compressors of other air supply units can continue to supply air to the dryer of that air supply unit through the main pipe. This avoids the entire system from shutting down due to a single equipment failure, reduces downtime caused by equipment maintenance or failure, improves the overall operating efficiency of the system, avoids the situation of some equipment operating under overload for a long time in the traditional one-to-one single-pipe mode, and improves the output quality of compressed air.

Description

Technical Field

[0001] This application relates to the field of gas supply system technology for smelting, and particularly to a gas supply system. Background Technology

[0002] Deeply dried instrument compressed air has become a basic requirement for modern steel plants. Traditionally, air compressors and dryers are connected in a one-to-one single-pipe configuration. When either the air compressor or the dryer malfunctions or requires maintenance, the other equipment (dryer or air compressor) must be forced to shut down, resulting in a reduction in the system's air supply capacity.

[0003] This connection method prevents equipment from being mutually redundant. If one device malfunctions, the entire system's operation is directly affected, as it cannot be supplemented or replaced by other equipment, limiting the overall system efficiency and reliability. Due to differences in the operating conditions of each unit (such as working pressure and flow rate) and factors like pipeline resistance, the flow distribution among the equipment cannot be uniform. Some dryers may therefore operate under overload conditions for extended periods. This uneven flow distribution and prolonged overload operation of some dryers leads to performance degradation, affecting the output quality of compressed air and failing to meet the high requirements of modern steel plants for deep-drying instrument compressed air. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a gas supply system to solve the problems of cumbersome operation and inability to provide uniform backup in the prior art.

[0005] The above-mentioned objectives of this application are mainly achieved through the following technical solutions:

[0006] A gas supply system, the gas supply system comprising:

[0007] The gas supply unit is provided with at least two sets. Each gas supply unit includes an air compressor and a dryer. The air compressor is used to drive the working gas to flow in a directional manner, and the dryer is used to dry the working gas. A first branch pipe is provided between the air compressor and the dryer, and a second branch pipe is connected in parallel with the first branch pipe, so that the working gas flows from the air compressor to the dryer through the first branch pipe and / or the second branch pipe.

[0008] The main pipe is connected in sequence to the air supply unit so that the air compressor in the air supply unit is connected to the dryer in another air supply unit.

[0009] In an optional embodiment, the first branch pipe is provided with a first control valve for controlling the flow rate of the working gas in the first branch pipe.

[0010] In an optional implementation, the first control valve is a straight-through valve.

[0011] In an optional implementation, the main pipe is connected to the second branch pipe in each of the gas supply units.

[0012] In an optional embodiment, the second branch pipe includes a first pipe section and a second pipe section, wherein the first pipe section connects the air compressor and the main pipe, and the second pipe section connects the dryer and the main pipe.

[0013] In an optional embodiment, the connection point between the first pipe segment and the second pipe segment is simultaneously connected to the main pipe.

[0014] In an optional embodiment, a second control valve is provided on the first pipe section for controlling the flow rate of the working gas in the first pipe section.

[0015] In an optional embodiment, a third control valve is provided on the second pipe section for controlling the flow rate of the working gas in the second branch pipe.

[0016] In an optional embodiment, the second control valve and the third control valve are backup valves.

[0017] In an optional implementation, the two ends of the main tube are sealed.

[0018] Compared with the prior art, the advantages of this application are:

[0019] The gas supply system in this application includes a main pipe and at least two sets of gas supply units. Each gas supply unit includes an air compressor and a dryer. The air compressor is used to drive the working gas to flow in a directional manner, and the dryer is used to dry the working gas. A first branch pipe is provided between the air compressor and the dryer, and a second branch pipe is connected in parallel with the first branch pipe, so that the working gas flows from the air compressor to the dryer through the first branch pipe and / or the second branch pipe. The main pipe is sequentially connected to the gas supply units, so that the air compressor in the gas supply unit is connected to the dryer in the other gas supply unit.

[0020] The working gas originates from the air compressor and flows to the dryer via the first branch pipe and / or the second branch pipe. The parallel connection of the first and second branch pipes provides two flow paths, increasing the system's flexibility. Connecting the various gas supply units via a main pipe allows gas to flow between different units. An air compressor in one supply unit can supply gas to the dryers in other supply units.

[0021] Because the main pipe connects all the air supply units, when one air compressor or dryer fails, the equipment in other air supply units can continue to work. If the air compressor in one air supply unit fails, the air compressors in other air supply units can continue to supply air to the dryer of that air supply unit through the main pipe, avoiding the shutdown of the entire system due to the failure of a single device, reducing downtime caused by equipment maintenance or failure, and improving the overall operating efficiency of the system.

[0022] The parallel connection of the first and second branch pipes provides multiple gas flow paths, allowing for flexible adjustment of gas flow distribution according to actual needs. When the compressor pressure of a certain air supply unit is high, some gas can be diverted through the second branch pipe, reducing the pressure on the first branch pipe and thus optimizing the gas distribution of the entire system. Connecting each air supply unit through the main pipe allows gas to flow between different units, avoiding the situation of some equipment operating under overload for a long time in the traditional one-to-one single-pipe mode, and improving the output quality of compressed air.

[0023] Furthermore, the air supply system is easy to expand flexibly. By adding new air supply units and connecting them to the main pipe, the system's air supply capacity can be further improved. By optimizing the gas flow path and flow distribution, the performance degradation caused by equipment overload operation is reduced, thereby ensuring the deep drying effect of compressed air and meeting the high requirements of modern steel plants for instrument compressed air.

[0024] The backup function and flexible gas distribution mechanism of the gas supply system enable the system to operate more stably and avoid gas quality fluctuations caused by equipment failure or maintenance. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0029] like Figure 1 As shown, Figure 1 A schematic diagram of a gas supply system is provided for embodiments of this application. The gas supply system includes a main pipe 300 and at least two sets of gas supply units 100, wherein:

[0030] The air supply unit 100 is provided in at least two sets. Each air supply unit 100 includes an air compressor 101 and a dryer 102. The air supply unit 100 is the core part of the system. Each set of air supply units 100 includes an air compressor 101 and a dryer 102. The main function of the air compressor 101 is to provide power to the system and drive the working gas to flow directionally in the target pipeline. It compresses air to convert low-pressure gas into high-pressure gas, providing the necessary pressure conditions for subsequent drying treatment.

[0031] The function of dryer 102 is to perform deep drying treatment on the working gas, removing moisture and other impurities from the gas, ensuring that the final output compressed air meets the requirements of industrial production for high-quality gas. Dryer 102 typically employs adsorption, refrigeration, or other efficient drying technologies to achieve the desired drying effect.

[0032] The air compressor 101 is used to drive the directional flow of the working gas, and the dryer 102 is used to dry the working gas. A first branch pipe 201 and a second branch pipe 202 connected in parallel with the first branch pipe 201 are provided between the air compressor 101 and the dryer 102, so that the working gas flows from the air compressor 101 to the dryer 102 through the first branch pipe 201 and / or the second branch pipe 202.

[0033] like Figure 1 As shown, the first branch pipe 201 is the main pipe connecting the air compressor 101 and the dryer 102, used to directly transport the high-pressure gas generated by the air compressor 101 to the dryer 102 for drying. The first branch pipe 201 is the main channel for gas flow, ensuring that the gas can flow efficiently from the air compressor 101 to the dryer 102.

[0034] like Figure 1As shown, the second branch pipe 202 is connected in parallel with the first branch pipe 201, and the second branch pipe 202 provides an additional path for gas flow. When the first branch pipe 201 cannot work properly due to maintenance, blockage or other reasons, the gas can continue to flow to the dryer 102 through the second branch pipe 202, ensuring the continuous operation of the system.

[0035] In addition, under certain operating conditions, the flow distribution of the first branch pipe 201 and the second branch pipe 202 can be adjusted to optimize the gas flow state, reduce pipe resistance, and improve the overall efficiency of the system.

[0036] like Figure 1 As shown, through the parallel design of the first branch pipe 201 and the second branch pipe 202, the working gas can flow from the air compressor 101 to the dryer 102 through the first branch pipe 201 and / or the second branch pipe 202. This flexible flow path provides more possibilities for the optimized operation of the system.

[0037] The main pipe 300 is sequentially connected to the air supply unit 100, so that the air compressor 101 in the air supply unit 100 is connected to the dryer 102 in another air supply unit 100.

[0038] The main pipe 300 connects each air supply unit 100 in sequence, integrating the individual air supply units 100 into a whole. Through the main pipe 300, the air compressor 101 in one air supply unit 100 can not only supply gas to the dryer 102 in that air supply unit 100, but also transport the gas to the dryers 102 in other air supply units 100 through the main pipe 300.

[0039] This ensures the system has reliable backup capabilities. When the air compressor 101 or dryer 102 in one of the air supply units 100 fails, the equipment in other air supply units 100 can continue to supply gas to the system through the main pipe 300, ensuring that the gas supply capacity of the entire system is not affected by the failure of a single device.

[0040] The presence of the main pipe 300 allows gas to flow between different gas supply units 100, and the gas distribution can be dynamically adjusted according to the actual operating status and needs of each unit. This effectively avoids long-term overload operation of some equipment, improving the overall operating efficiency of the system and the output quality of compressed air.

[0041] With the main pipe 300 connection and branch pipe parallel design, the system has a strong mutual backup function, which reduces downtime caused by equipment failure or maintenance and significantly improves the reliability of the system.

[0042] By optimizing gas distribution and coordinating equipment operation, the overload operation of some equipment is reduced, ensuring the deep drying effect of compressed air and meeting the production requirements for high-quality gas.

[0043] The gas supply system in this application includes a main pipe 300 and at least two sets of gas supply units 100. Each gas supply unit 100 includes an air compressor 101 and a dryer 102. The air compressor 101 is used to drive the working gas to flow in a directional manner, and the dryer 102 is used to dry the working gas. A first branch pipe 201 is provided between the air compressor 101 and the dryer 102, and a second branch pipe 202 is connected in parallel with the first branch pipe 201, so that the working gas flows from the air compressor 101 to the dryer 102 through the first branch pipe 201 and / or the second branch pipe 202. The main pipe 300 is sequentially connected to the gas supply units 100, so that the air compressor 101 in the gas supply unit 100 is connected to the dryer 102 in another gas supply unit 100.

[0044] The working gas originates from the air compressor 101 and flows to the dryer 102 via the first branch pipe 201 and / or the second branch pipe 202. The parallel connection of the first branch pipe 201 and the second branch pipe 202 provides two flow paths, increasing the system's flexibility. The various gas supply units 100 are connected via the main pipe 300, allowing gas to flow between different gas supply units 100. The air compressor 101 in one gas supply unit 100 can supply gas to the dryer 102 in other gas supply units 100.

[0045] like Figure 1 As shown, since the main pipe 300 connects to each air supply unit 100, when a certain air compressor 101 or dryer 102 fails, the equipment of other air supply units 100 can continue to work. If the air compressor 101 of a certain air supply unit 100 fails, the air compressor 101 of other air supply units 100 can continue to supply air to the dryer 102 of that air supply unit 100 through the main pipe 300, avoiding the shutdown of the entire system due to the failure of a single device, reducing downtime caused by equipment maintenance or failure, and improving the overall operating efficiency of the system.

[0046] like Figure 1 As shown, the parallel connection of the first branch pipe 201 and the second branch pipe 202 provides multiple gas flow paths, allowing for flexible adjustment of gas flow distribution according to actual needs. When the pressure of the air compressor 101 in a certain air supply unit 100 is high, some gas can be diverted through the second branch pipe 202, reducing the pressure on the first branch pipe and thus optimizing the gas distribution of the entire system. Connecting each air supply unit 100 through the main pipe 300 allows gas to flow between different units, avoiding the situation of some equipment operating under overload for a long time in the traditional one-to-one single-pipe mode, and improving the output quality of compressed air.

[0047] Furthermore, the air supply system is easy to expand flexibly. By adding a new air supply unit 100 and connecting it to the main pipe 300, the system's air supply capacity can be further improved. By optimizing the gas flow path and flow distribution, the performance degradation caused by equipment overload operation is reduced, thereby ensuring the deep drying effect of compressed air and meeting the high requirements of modern steel plants for instrument compressed air.

[0048] The system's backup function and flexible gas distribution mechanism enable the system to operate more stably and avoid gas quality fluctuations caused by equipment failure or maintenance.

[0049] like Figure 1 As shown, in an optional embodiment, the first branch pipe 201 is provided with a first control valve 401 for controlling the flow rate of the working gas in the first branch pipe 201.

[0050] A first control valve 401 is installed on the first branch pipe 201, which controls the flow rate of the working gas in the first branch pipe 201. By adjusting the opening of the first control valve 401, the flow rate of gas from the air compressor 101 to the dryer 102 can be precisely controlled, ensuring that the gas treatment effect in the dryer 102 reaches the optimal state. The first control valve 401 enables the system to dynamically adjust the gas flow rate according to actual needs, improving the system's flexibility and adaptability.

[0051] like Figure 1 As shown, in an optional embodiment, the first control valve 401 is a straight-through valve. The first control valve 401 is a straight-through valve. Straight-through valves are characterized by simple structure, convenient operation, and good sealing performance, enabling rapid response to flow regulation needs and ensuring the stability and controllability of gas flow. The design of the straight-through valve allows the system to efficiently control gas flow during operation, reducing gas leakage or flow fluctuations caused by valve malfunction or improper operation.

[0052] like Figure 1 As shown, in an optional embodiment, the main pipe 300 is connected to the second branch pipe 202 in each of the gas supply units 100.

[0053] like Figure 1 As shown, in an optional embodiment, the main pipe 300 is connected to a second branch pipe 202 in each air supply unit 100. This connects the second branch pipe 202 not only to the air compressor 101 and dryer 102, but also to the main pipe 300, further enhancing the system's flexibility and redundancy. Through the connection of the main pipe 300, gas can flow between different air supply units 100, optimizing the gas distribution of the entire system.

[0054] like Figure 1As shown, in an optional embodiment, the second branch pipe 202 includes a first pipe section 203 and a second pipe section 204, wherein the first pipe section 203 connects the air compressor 101 and the main pipe 300, and the second pipe section 204 connects the dryer 102 and the main pipe 300.

[0055] The second branch pipe 202 includes a first pipe section 203 and a second pipe section 204, enabling the second branch pipe 202 to simultaneously undertake the functions of gas input and output, further enhancing the system's flexibility and backup capability.

[0056] In an optional embodiment, the connection point between the first pipe segment 203 and the second pipe segment 204 is simultaneously connected to the main pipe 300.

[0057] like Figure 1 As shown, in an optional embodiment, the connection point between the first pipe section 203 and the second pipe section 204 is also connected to the main pipe 300. This allows gas to flow freely between the first pipe section 203 and the second pipe section 204, and also enables gas exchange with other gas supply units 100 through the main pipe 300. This not only optimizes the gas flow path but also improves the overall operating efficiency of the system.

[0058] like Figure 1 As shown, in an optional embodiment, a second control valve 402 is provided on the first pipe section 203 to control the flow rate of the working gas in the first pipe section 203.

[0059] A second control valve 402 is installed on the first pipe section 203, which controls the flow rate of the working gas within the first pipe section 203. By adjusting the opening of the second control valve 402, the flow rate of gas from the air compressor 101 through the first pipe section 203 to the main pipe 300 can be precisely controlled. This allows the system to dynamically adjust the gas flow rate according to actual needs, ensuring that the gas distribution in the main pipe 300 reaches the optimal state.

[0060] like Figure 1 As shown, in an optional embodiment, a third control valve 403 is provided on the second pipe section 204 to control the flow rate of the working gas in the second branch pipe 202.

[0061] A third control valve 403 is installed on the second pipe section 204, which controls the flow rate of the working gas within the second pipe section 204. By adjusting the opening of the third control valve 403, the flow rate of gas from the dryer 102 through the second pipe section 204 to the main pipe 300 can be precisely controlled. This allows the system to dynamically adjust the gas flow rate according to actual needs, ensuring that the gas distribution in the main pipe 300 reaches the optimal state.

[0062] In an optional embodiment, the second control valve 402 and the third control valve 403 are mutually redundant valves. When one control valve fails or requires maintenance, the other control valve can continue to operate as a backup valve, ensuring the normal operation of the system. This significantly improves the reliability and operational stability of the system and reduces system downtime caused by a single valve failure.

[0063] In an optional embodiment, the two ends of the main pipe 300 are sealed. This ensures that the gas inside the main pipe 300 does not leak into the external environment, and also prevents external air or other impurities from entering the main pipe 300. The sealing not only improves system safety but also ensures the purity of the gas and the stability of system operation.
