Abstract
Description
Technical Field
[0001] This utility model relates to the field of air compressor hydrophobic technology, and in particular to an intelligent zero-air-consumption hydrophobic device. Background Technology
[0002] Air contains moisture. After being compressed by an air compressor, the air is heated and pressurized. The water in the air exists in the form of water vapor. When cooled by a cooler, a large amount of condensate is produced. If the condensate is not drained in time, it will accumulate in the air circulation channels, reducing the air circulation area. In severe cases, it can cause the air compressor to surge and stop or even damage the equipment. In addition, the accumulation of condensate in pipes and containers can more easily trigger corrosion and rust problems, reducing the service life of pipes and equipment. Therefore, during equipment operation, it is necessary to drain the condensate from the intercooler and the air reservoir in a timely manner. The device that blocks air and drains water is the steam trap.
[0003] Whether mechanical or electric, steam traps often experience blockages and direct exhaust during malfunctions, resulting in high maintenance and replacement costs and potentially affecting the safe operation of the air compressor. As a result, most users have eliminated steam traps and adopted manual valves to control direct exhaust, which leads to gas-liquid entrainment and compressed air leakage during the drainage process.

This results in high maintenance and replacement costs and may affect the safe operation of the air compressor. As a result, most users have eliminated condensate drains and adopted manual valves to control direct exhaust, which leads to gas-liquid entrainment and compressed air leakage during the condensation process.

[0018] like Figure 1As shown, the technical solution in this application embodiment effectively solves the problem of frequent blockages and direct exhaust during malfunctions in both mechanical and electric steam traps, resulting in high maintenance and replacement costs and potentially affecting the safe operation of the air compressor. Therefore, most users have eliminated steam traps and adopted manual valves to control direct exhaust, leading to gas-liquid entrainment and compressed air leakage during the drainage process. The overall concept is as follows: an intelligent zero-air-consumption steam trap includes a slag-water separator 10, an overflow pipe 20, a gas-water separator 30, a level gauge 40, and a control system 50. The slag-water separator 10 and the gas-water separator 30 are connected through the overflow pipe 20. The level gauge 40 is designed to... Inside the gas-water separator 30, an inlet pipe 11 is provided at the upper part of the slag-water separator 10, a baffle plate 12 is provided in the middle of the slag-water separator 10, a conical slag settling zone 13 is provided at the lower part of the slag-water separator 10, and a drain solenoid valve 14 is provided at the bottom of the slag-water separator 10. An air balance pipe 31 is provided on the gas-water separator 30 and is connected to the slag-water separator 10. A drain pipe 32 is provided inside the gas-water separator 30, and a drain solenoid valve 33 is connected to the side of the drain pipe 32 away from the gas-water separator 30. The level gauge 40 includes an electric contact level gauge 41 and a plastic tube level gauge 42. The control system 50 is electrically connected to the electric contact level gauge 41, the drain solenoid valve 33, and the drain solenoid valve 14.
[0019] To address the problems existing in the prior art, this utility model provides an intelligent zero-air-consumption condensate drain device that can maintain the maximum flow area of the compressor drain pipe, ensure that no exhaust is emitted during condensation, and features such as avoiding condensate blockage, automatic slag removal, reduced energy consumption, and remote monitoring.
[0020] Working principle:
[0021] In the first step, when the equipment drains water from the air compressor, the drained water enters the slag-water separator 10 through the inlet pipe 11. Under the action of the baffle plate 12, the air and water settle into the conical slag area 13. After the slag settles, it is periodically discharged through the drain solenoid valve 14. The air-water mixture is introduced into the air-water separator 30 through the overflow pipe 20. In the air-water separator 30, the air returns to the slag-water separator 10 through the air balance pipe 31, and the water accumulates and rises in the air-water separator 30. When it reaches the high level of the electric contact level gauge 41, it sends a signal to the control system 50 to control the drain solenoid valve 33 to open, and the water in the air-water separator 30 is discharged. When the water level drops to the low level of the electric contact level gauge 41, it sends a signal to the control system 50 to control the drain solenoid valve 33 to close. At this time, the draining process during normal operation is completed.
[0022] The second step is that if the water level in the gas-water separator 30 reaches the high level of the electric contact level gauge 41, a signal is sent to the control system 50 to control the drain solenoid valve 33 to open. If the opening time exceeds 15 seconds (which can be set by the user) and the low level is not received from the electric contact level gauge 41, the drain solenoid valve 14 will open and an alarm will be sent to the DCS.
[0023] If the water level in the gas-water separator 30 reaches the low level of the electric contact level gauge 41, a signal is sent to the control system 50 to control the drain solenoid valve 33 to close. If the low level of the electric contact level gauge 41 has not disappeared after the closing time exceeds 15 seconds (which can be set by the user), an alarm is sent to the DCS.
[0024] If the device loses power, the drain solenoid valve 14 will open; this enables the remote monitoring and alarm function of the intelligent zero-gas-consumption condensate drain device.
[0025] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
