Description

Technical Field

[0001] The utility model relates to the field of gas production, in particular to a continuous air storage tank without air loss during sewage discharge. Background Art

[0002] During the use of an air storage tank, it is usually connected to an air compressor. During the air compression process, the water vapor in the air is compressed as a whole. Since the exhaust temperature is relatively high, while the inner wall temperature of the air storage tank is at room temperature. Therefore, during the use of the air storage tank, a large amount of condensed water will accumulate in the air tank. If the water is not drained in time, the condensed water will continue to accumulate in the air storage tank. When the moisture accumulates to a certain extent, the condensed water will flow into the rear outlet pipeline through the compressed air outlet, posing a great potential safety hazard to the safe operation of the equipment.

[0003] The traditional treatment method is to install an electric sewage discharge valve at the lower end of the air storage tank. The condensed water in the air storage tank is discharged through the form of regular automatic drainage. However, this mode has the following two drawbacks. 1. The automatic drainer needs to be provided with a power cord and wiring is required. 2. During the drainage process, the compressed gas is also discharged accordingly. Therefore, there is a relatively large air loss, and the air loss accounts for about 10-15% of the compressed air. When selecting the air compressor, the margin design of the compressed air volume of the air compressor needs to be considered. The selection of the air compressor needs to be increased, and the corresponding economic cost is increased.

[0004] In view of the above problems in the prior art, there is currently no effective solution. Content of the Utility Model

[0005] To solve the above problems, the utility model provides a continuous air storage tank without air loss during sewage discharge. By setting up a gas-water separator without air loss, while discharging the sewage, the compressed air is transported back into the tank body, thus solving the cumbersome problem of wiring required for the electric sewage discharge valve in the prior art and the problem of relatively large air loss.

[0006] To achieve the above object, the utility model provides a continuous air storage tank without air loss during sewage discharge, including: a tank body, the tank body is connected with an air inlet pipeline, an air outlet pipeline and a drainage pipeline; a first gate valve, the first gate valve is arranged on the drainage pipeline; a gas-water separation device, the gas-water separation device is connected with the drainage pipeline; a sewage discharge pipeline, the sewage discharge pipeline is connected with the gas-water separation device and is used for discharging the sewage separated by the gas-water separation device; a return pipeline, the air inlet end of the return pipeline is connected with the gas-water separation device, and the air outlet end is connected with the tank body and is used for transporting the compressed air separated by the gas-water separation device back to the tank body.

[0007] Further optionally, the tank body is connected with a pressure gauge.

[0008] Further optionally, a safety valve is connected to the tank body.

[0009] Further optionally, the intake pipeline and the exhaust pipeline are respectively located on both sides of the tank body; connecting flanges are provided on both the intake pipeline and the exhaust pipeline.

[0010] Further optionally, reinforcing ribs are provided on the inner wall of the tank body; the reinforcing ribs are arranged at equal intervals along the axial direction of the tank body.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0019] Please refer to Figure 1 , Figure 1 which is the continuous air storage tank without air loss for sewage discharge provided by the embodiments of the present utility model. The embodiments of the present utility model provide a continuous air storage tank without air loss for sewage discharge, including: a tank body 1, the tank body 1 is connected with an air inlet pipeline 2, an air outlet pipeline 3 and a drainage pipeline 4; a first gate valve 5, the first gate valve 5 is arranged on the drainage pipeline 4; a gas-water separation device 6, the gas-water separation device 6 is connected with the drainage pipeline 4; a sewage discharge pipeline 7, the sewage discharge pipeline 7 is connected with the gas-water separation device 6 and is used for discharging the sewage separated by the gas-water separation device 6; a return pipeline 8, the air inlet end of the return pipeline 8 is connected with the gas-water separation device 6, and the air outlet end is connected with the tank body 1, and is used for conveying the compressed air separated by the gas-water separation device 6 back to the tank body 1.

[0020] The tank body 1 is arranged behind the air compressor, that is, the air inlet end of the air inlet pipeline 2 is connected with the air compressor, and the compressed air obtained after being processed by the air compressor enters the inside of the tank body 1 through the air inlet pipeline 2 and flows out through the air outlet pipeline 3. The connection end of the air outlet pipeline 3 can be connected with different devices according to different implementation requirements. For example, if oxygen is to be produced, a gas separation tank can be connected.

[0021] The drainage pipeline 4 is located at the bottom of the tank body 1 and is controlled by the first gate valve 5. The first gate valve 5 is a manual gate valve and can be opened according to requirements to achieve subsequent sewage discharge performance.

[0022] The gas-water separation device 6 is a gas-water separator without pressure loss. Compressed air enters the gas-water separation device 6, and after passing through the gas-water separation device 6, the condensed water gradually accumulates. Then the float ball carrying the condensed water in the device opens after exceeding a certain liquid level. When the condensed water is lower than the sewage discharge liquid level, the drainage of the device is closed. The condensed water flows out through the sewage discharge pipeline 7, and at the same time, the compressed gas returns to the tank body 1 through the return pipeline 8.

[0023] As an optional implementation manner, the tank body 1 is connected with a pressure gauge 9.

[0024] During the use of the tank body 1, the pressure gauge 9 can monitor the gas pressure inside the tank body 1 in real time.

[0025] As an optional implementation manner, the tank body 1 is connected with a safety valve 10.

[0026] When the pressure inside the tank body 1 reaches a certain value, the safety valve 10 can be controlled to relieve pressure to achieve overpressure protection for the entire tank body 1.

[0027] As an optional implementation manner, the air inlet pipeline 2 and the air outlet pipeline 3 are respectively located on both sides of the tank body 1; connection flanges are provided on both the air inlet pipeline 2 and the air outlet pipeline 3.

[0028] The intake pipe 2 and the outlet pipe 3 are arranged opposite to each other and are respectively disposed on both sides of the tank body 1, which helps to form a more reasonable air flow path. Compressed air enters the tank body 1 from one side, flows inside the tank body 1 and fully utilizes the volume of the storage tank, and finally discharges from the other side. This can ensure the uniform distribution of air in the tank body 1, avoid the retention of air in some areas or the phenomenon of uneven local pressure. At the same time, it makes the air flow through a longer path inside the tank body 1. As the air flows through a larger area inside the tank body 1, the temperature gradually decreases, and the condensed water is more likely to precipitate from the air and deposit at the bottom of the tank body 1. This design helps to improve the efficiency of condensed water separation.

[0029] In addition, connecting flanges are provided on both the intake pipe 2 and the outlet pipe 3 for tightly connecting with external equipment.

[0030] As an optional implementation manner, reinforcing ribs are provided on the inner wall of the tank body 1; the reinforcing ribs are arranged at equal intervals along the axial direction of the tank body 1.

[0031] Reinforcing ribs are provided on the inner wall of the tank body 1 to increase the structural strength of the tank body 1.

[0032] The reinforcing ribs are arranged at equal intervals along the axial direction of the tank body 1, and the thickness of each reinforcing rib gradually decreases along the radial direction to reduce the air flow resistance in the inner cavity of the tank body 1.

[0033] A filter screen is provided in the sewage discharge pipe 7.

[0034] A filter screen is provided in the sewage discharge pipe 7 to prevent external impurities from entering the inside of the tank body 1. The filter screen can be realized by a wire mesh.

[0035] As an optional implementation manner, a waterproof coating is provided inside the tank body 1.

[0036] A waterproof coating is provided inside the tank body 1, such as a polytetrafluoroethylene (PTFE) coating, an epoxy resin coating, etc.

[0037] It can prevent the retention of condensed water inside the tank body 1 and promote the water droplets to slide to the drain outlet.

[0038] As an optional implementation manner, a lifting lug is provided at the top of the tank body 1.

[0039] A lifting lug is provided at the top of the tank body 1. The lifting lug is a metal member welded to the outer wall of the storage tank body and is used to provide support during handling or installation. The thickness of the lifting lug is 5 mm to 15 mm, and the position of the lifting lug is at the center of the top end of the tank body 1.

[0040] The above technical solution has the following beneficial effects: By using this air storage tank, there is no need to lay power lines, which reduces the complexity of the setup and the maintenance time caused by line failures; When selecting an air compressor, there is no need to consider the compressed air consumed by the automatic drainage of the air storage tank, thereby effectively reducing the economic cost and response energy consumption of the air compressor; Recycling the discharged compressed air improves the utilization rate of the compressed air.

[0041] The specific implementation manners of the above utility model further elaborate on the purpose, technical solution and beneficial effects of the utility model. It should be understood that the above content is only the specific implementation manners of the utility model and is not used to limit the protection scope of the utility model.
