Description

Technical Field

[0001] This utility model belongs to the field of compressed air systems, and specifically relates to a condensate drainage system. Background Technology

[0002] Compressed air, as a commonly used power source and working medium, occupies an indispensable position in modern industry and many other fields. In the industrial sector, it is the key power source for driving various pneumatic tools and realizing pneumatic control and automated production processes. From the precise operation of machine tools in machinery manufacturing to the efficient assembly of automobile manufacturing production lines, from the smooth operation of looms in the textile industry to the cleaning and material conveying of equipment in the food processing industry, compressed air plays a vital role. In the energy sector, compressed air energy storage technology, as a highly promising new energy storage method, can convert electrical energy into the internal energy of compressed air and store it during off-peak grid loads. During peak electricity demand, this energy is released to drive generators, effectively achieving peak shaving and valley filling, improving energy utilization efficiency, contributing to the optimization and sustainable development of the energy structure, and providing strong support for the grid connection of renewable energy, alleviating the problems caused by the intermittency and volatility of its power generation. The task of a compressed air system is to supply the required air volume to the equipment in a timely manner, while meeting the equipment's requirements for compressed air pressure, cleanliness, and dryness. A compressed air system includes an air tank and air pipes, both of which contain compressed air.

[0003] In practice, it has been found that condensation frequently occurs inside the cylinders and pipes of compressed air systems, accumulating there. To address this issue, current technologies typically incorporate drain pipes on the cylinders and pipes to remove the condensation. However, this process requires manual operation, increasing the workload for staff and contradicting the trend towards intelligent and automated systems. Utility Model Content

[0004] This invention provides a condensate drainage system, the purpose of which is to solve the problem that existing technologies require manual condensate drainage.

[0005] To achieve the above objectives, this utility model provides a condensate drainage system, including a discharge pipe for connecting to a gas tank or gas transmission pipeline to discharge condensate from the gas tank or gas transmission pipeline, and a first valve configured on the discharge pipe; a level gauge for detecting the condensate level in the gas tank or gas transmission pipeline; and a controller for signal connection to the level gauge and the first valve.

[0006] This solution uses a level gauge to detect the condensate level. When the level reaches a threshold, the level gauge sends the data back to the controller, which then opens the first valve, allowing the condensate to be discharged to the outside through the drain pipe. This prevents condensate from accumulating in the gas tank or gas pipeline. By coordinating the level gauge and the first valve, this solution ensures that condensate is automatically discharged after reaching a certain level, overcoming the shortcomings of existing technologies that require manual discharge.

[0007] Preferably, to further ensure timely drainage of condensate, this solution also includes a timer, which is signal-connected to the controller. This solution uses the timer to measure the closing time of the first valve. When the closing time of the first valve reaches a threshold, regardless of the level gauge reading, the controller will open the first valve to drain the condensate and prevent its prolonged accumulation.

[0008] Preferably, the level gauge is installed on the discharge pipe.

[0009] Preferably, in order to facilitate both manual and automatic drainage, the first valve in this solution is a manual-automatic integrated valve.

[0010] Preferably, because the compressed air pressure inside the gas tank and gas pipeline is relatively high, the first valve is prone to damage due to prolonged pressure impact. To prevent compressed air leakage caused by damage to the first valve, this solution also includes a detector and an alarm, both of which are signal-connected to the controller; the detector is installed on the discharge pipe, with the first valve located at the inlet of the discharge pipe and the detector located at the outlet of the discharge pipe.

[0011] In this scheme, after the first valve is closed, the detector checks the internal state of the discharge pipe. When an abnormality occurs in the discharge pipe, the detector feeds back the result to the controller, which then activates the alarm to remind the operator to handle the situation promptly.

[0012] Preferably, the detector is an ultrasonic detector.

[0013] Preferably, the system further includes a sampling component installed on the discharge pipe and connected to the controller via a signal connection. The sampling component allows for the sampling of the discharged condensate, which can then be analyzed to obtain information about the internal state of the gas tank and gas pipeline.

[0014] Preferably, in order to achieve condensate sampling, the sampling assembly includes a sampling tube and a sampling container, wherein the inlet of the sampling tube is connected to the inside of the discharge pipe, and the outlet of the sampling tube is connected to the sampling container.

[0015] This method connects a sampling pipe to a discharge pipe, allowing condensate from the discharge pipe to enter the sampling pipe. The condensate then flows through the sampling pipe into a sampling container, where it is stored.

[0016] Preferably, to prevent condensate and compressed air from leaking from the sampling tube, the connection between the sampling tube and the discharge tube in this embodiment is located at the rear end of the first valve.

[0017] Preferably, in order to control the total amount of condensate sampled, a second valve is provided at the inlet of the sampling tube in this solution, and the second valve is signal-connected to the controller.

[0018] The beneficial effects of this invention are as follows: This solution detects the condensate level using a level gauge. When the level reaches a threshold, the level gauge feeds the data back to the controller, which then opens the first valve, allowing the condensate to be discharged to the outside through the drain pipe, thus preventing condensate from accumulating in the gas tank or gas pipeline. This solution, through the coordination of the level gauge and the first valve, ensures that the condensate is automatically discharged after reaching a certain level, overcoming the shortcomings of existing technologies that require manual discharge.

[0024] To make the objectives, technical solutions, and advantages of the embodiments clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0025] The basic implementation examples are as follows: Figure 1 and attached Figure 2 As shown, a condensate drainage system includes a drain pipe 3, a level gauge 4, a timer, and a controller 6.

[0026] In this embodiment, the discharge pipe 3 is used to connect to the gas tank 1 or the gas transmission pipeline 2, so that the condensate inside the gas tank 1 or the gas transmission pipeline 2 can be discharged outward through the discharge pipe 3, preventing the condensate from accumulating inside the gas tank 1 or the gas transmission pipeline 2. The discharge pipe 3 can be welded to the gas tank 1, and the connection point between the discharge pipe 3 and the gas tank 1 is located at the bottom of the gas tank 1; the discharge pipe 3 can be connected to the gas transmission pipeline 2 through a connector, and the connection point between the discharge pipe 3 and the transmission pipeline can be located at the lowest point of the gas transmission pipeline 2 to ensure normal discharge of condensate.

[0027] In this embodiment, a first valve 5 is provided on the discharge pipe 3, which can open and close the discharge pipe 3. When the discharge pipe 3 is closed, condensate cannot be discharged, preventing compressed air leakage. When the discharge pipe 3 is open, condensate can be discharged normally to the outside, solving the problem of condensate accumulation. The first valve 5 is preferably a manual-automatic integrated valve. The manual-automatic integrated valve can be operated manually or electrically. Manual operation meets the needs of manual drainage, while electric operation meets the needs of remote control of drainage. Of course, in some embodiments, if manual drainage is not required, the first valve 5 can also be set as a conventional electric valve.

[0028] In this embodiment, the level gauge 4 is installed on the discharge pipe 3. Since the discharge pipe 3 is connected to the gas tank 1 or the gas transmission pipeline 2, the liquid in the gas tank 1 or the gas transmission pipeline 2 can enter the discharge pipe 3 and be detected by the level gauge 4 installed on the discharge pipe 3. When the condensate in the discharge pipe 3 accumulates to a certain level, the condensate can be discharged. The level gauge 4 can be a conventional level gauge 4. When the level gauge 4 is installed on the discharge pipe 3 connected to the gas tank 1, the level gauge 4 can detect the condensate level in the gas tank 1; when the level gauge 4 is installed on the discharge pipe 3 connected to the gas transmission pipeline 2, the level gauge 4 can detect the condensate level in the liquid transmission pipeline network.

[0029] It should be noted that in some embodiments, a level gauge 4 may also be configured on the gas tank 1 or the gas pipeline network 2 to detect the liquid level. The level gauge 4 can be installed at the bottom of the gas tank 1 to detect the liquid level. The level gauge 4 can be installed at the lowest end of the gas pipeline network 2 to detect the liquid level within the gas pipeline network 2.

[0030] The timer in this embodiment is a conventional timer. The timer can be installed inside the control room, or it can be installed on the discharge pipe 3. The timer is used to record the closing time and opening time of the first valve 5, so that the operator can operate according to the recorded time.

[0031] In this embodiment, the level gauge 4, the first valve 5, and the timer are all connected to the controller 6 via signal connections. The controller 6 can be a PLC control module, a microcontroller control module, or an industrial computer control module, as is available in the prior art. The controller 6 can be installed inside the control room and then connected to each component via cables.

[0032] The following detailed description illustrates the implementation method: When condensate accumulates inside the gas tank 1 or the gas pipeline 2, the condensate level rises. The level gauge 4 feeds back the level information to the controller 6. When the level exceeds a first threshold, the controller 6 controls the first valve 5 to open, allowing the condensate to be discharged outwards along the drain pipe 3. When the level is below a second threshold, the controller 6 controls the first valve 5 to close, preventing liquid leakage.

[0033] Simultaneously, the timer records the closing time of the first valve 5. If the closing time of the first valve 5 exceeds a threshold, the timer sends a signal to the controller 6, which then controls the first valve 5 to open, allowing the condensate to be discharged along the drain pipe 3. The timer ensures that the condensate is discharged at least periodically.

[0034] Example 2

[0035] This embodiment is an improvement on embodiment 1, such as... Figure 3 As shown, in this embodiment, to prevent compressed gas leakage due to damage to the first valve 5, a detector 7 is installed on the discharge pipe. The detector 7 is preferably an ultrasonic detector 7, which is used to detect whether there is a leak inside the discharge pipe. The detector 7 is in a signal connection state with the controller 6.

[0036] The working process is described below: After the controller 6 closes the first valve 5 for a fixed time (e.g., after 5 minutes), the controller 6 controls the detector 7 to operate, and the detector 7 detects the internal state of the discharge pipe. If the detector 7 detects that there is liquid inside the discharge pipe and that it is in a flowing state, it indicates that the first valve 5 is damaged and needs to be maintained in time to avoid a large leakage of compressed gas.

[0037] Example 3

[0038] This embodiment is an improvement on embodiment 1 or embodiment 2, such as... Figure 4 As shown in the figure. In order to determine whether there is any damage inside the gas tank 1 or the gas pipeline, a sampling component is installed on the discharge pipe. By periodically sampling the discharged condensate, and then analyzing whether there are a large number of impurities and special foreign objects in the condensate, it can be determined whether there is any damage inside the gas tank 1 or the gas pipeline.

[0039] The sampling assembly in this embodiment includes a sampling tube 8 and a sampling container 9. The sampling tube 8 is connected to the discharge pipe via a tee connector. When condensate is discharged along the discharge pipe, some of the condensate enters the interior of the sampling tube 8 and flows along it. A sampling container 9, which can be a sampling bottle, is provided at the outlet of the sampling tube 8. The condensate flowing along the sampling tube 8 can enter the interior of the sampling bottle.

[0040] To prevent gas leakage, the connection between the sampling tube 8 and the discharge tube is located at the rear end of the first valve 5. That is, condensate can only enter the sampling tube 8 when the first valve 5 is open, ensuring normal condensate sampling.

[0041] To prevent excessive condensate from being collected during sampling, a second valve 10 is installed at the inlet of the sampling tube 8. The second valve 10 can be a conventional point valve or a manual / automatic valve. The second valve 10 closes the inlet of the sampling tube 8, preventing excess condensate from entering. Of course, to ensure normal sampling during condensate drainage, the second valve 10 is connected to the controller 6. When the controller 6 opens the first valve 5 to drain the condensate, the controller 6 then opens the second valve 10, allowing condensate to enter the sampling tube 8 through the second valve 10.

[0042] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
