Description

Technical Field

[0001] The utility model belongs to the technical field of gas drying equipment, and particularly relates to an energy-saving and environment-friendly zero-gas-consumption gas drying machine drainage structure. Background Art

[0002] Since there is a lot of moisture in the ambient air, this part of water will produce condensed water due to changes in temperature and pressure after entering the compressor for compression, which will affect the operation of the compressor unit and the performance and life of other gas-using equipment. Therefore, removing moisture from the air is very important to ensure the normal operation of the pneumatic system.

[0003] At present, a Chinese utility model with publication number: CN216282379U discloses a drainage structure for a centrifugal dryer, including a centrifugal dryer body and a water-cooled motor arranged on one side of the centrifugal dryer body, and a drainage port opened on one side of the water-cooled motor, one side of the drainage port is fixedly connected with a drainage pipe 1, and the interior of the drainage pipe 1 is movably connected with a sealing column, one side of the drainage pipe 1 is fixedly connected with a threaded pipe, the interior of the threaded pipe is screwed and connected with a threaded knob, a rotating shaft is arranged between the threaded knob and the sealing column and the rotating shaft is located inside the threaded pipe, a buffer pressure relief member is arranged at the bottom end of the drainage pipe 1, and a drainage pipe 2 is arranged at the bottom end of the buffer pressure relief member, the coolant discharged from the water-cooled motor passes through the drainage pipe 1 buffer pressure relief member and the drainage pipe 2 in turn, and the coolant discharged from the outside is buffered and reduced in pressure by the buffer pressure relief member, so that the coolant is not easy to spray out during the discharge process, and the operation is safer and more convenient.

[0004] Traditional dryers, such as blast heat regeneration dryers, consume a lot of compressed air during the regeneration process. In particular, when removing moisture from the compressed air, they consume additional compressed air and generate high energy consumption, thereby reducing energy utilization efficiency. This not only increases production costs, but also violates the principles of energy conservation and environmental protection. At the same time, in the process of removing moisture from the compressed air, it is impossible to separate clean and turbid water from the water, making it difficult to separate impurities from the water and reducing the smoothness of pipeline drainage. Utility Model Content

[0005] The purpose of the utility model is to provide an energy-saving and environmentally friendly zero-gas consumption gas dryer drainage structure, which has the advantages of not only being able to efficiently remove moisture from compressed air without consuming additional compressed air, but also being able to separate and discharge the moisture removed from the compressed air, making it easier to handle impurities in the moisture.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions: an energy-saving and environmentally friendly zero-gas consumption gas dryer drainage structure, including a gas-liquid separator, a drainage liquid storage tank is arranged at the bottom of the gas-liquid separator, the bottom of the gas-liquid separator is fixedly connected with a first connecting pipe fixedly connected to the bottom of the inner cavity of the drainage liquid storage tank, a liquid level transmitter and a magnetic flap liquid level gauge are fixedly installed on both sides of the bottom of the gas-liquid separator, the bottom of the drainage liquid storage tank is fixedly connected with a second connecting pipe, and the two sides of the second connecting pipe are fixedly connected with third connecting pipes, and the ends of the two third connecting pipes away from the second connecting pipe are fixedly installed with a first programmable valve and a second programmable valve, respectively, and the ends of the first programmable valve and the second programmable valve away from the third connecting pipe are fixedly connected to a main drainage pipe through pipelines.

[0007] By adopting the above technical solution, the drainage process is automatically started according to the preset drainage cycle or real-time water level information. When condensed water is generated inside the gas dryer, the automatic drainage device will discharge the condensed water. This avoids the energy waste caused by gas leakage in the traditional drainage method, achieves zero gas consumption drainage, improves the drainage speed and efficiency, makes the production process smoother, and improves production efficiency; by discharging the water removed from the compressed air into the bottom of the inner cavity of the drainage liquid storage tank through the first connecting pipe. And use the filter net to filter the water into upper and lower layers inside the first connecting pipe, so that the fourth connecting pipe and the second connecting pipe can respectively discharge the clean water and turbid water in the upper and lower layers of the drainage liquid storage tank through two different pipes. This makes it easy to handle impurities in the water and ensures the smoothness of pipeline drainage.

[0008] The utility model is further configured as follows: a fourth connecting pipe is fixedly connected through the interior of the second connecting pipe and is fixedly connected to the top of the inner cavity of the drainage liquid storage tank; a filter is fixedly connected to the middle layer inside the drainage liquid storage tank; an end of the fourth connecting pipe away from the drainage liquid storage tank is fixedly connected to a third program-controlled valve; an end of the third program-controlled valve away from the fourth connecting pipe is fixedly connected through a pipeline to a side drainage pipe that is fixedly connected to one side of the interior of the main drainage pipe.

[0009] By adopting the above technical solution, the fourth connecting pipe and the second connecting pipe can respectively discharge the clean water and turbid water in the upper and lower layers of the drainage liquid storage tank through two different pipes, thereby facilitating the treatment of impurities in the water and ensuring the smoothness of pipeline drainage.

[0010] The utility model is further configured as follows: a first control circuit and a second control circuit are electrically connected between the liquid level transmitter and the first program-controlled valve, and between the magnetic flap liquid level gauge and the second program-controlled valve, respectively.

[0011] The above technical solution is used to convert the liquid level signal measured by the liquid level transmitter and the magnetic flap liquid level gauge into a standard signal output, and control the first program-controlled valve and the second program-controlled valve to open or close.

[0012] The utility model is further configured as follows: both ends of the first program-controlled valve, the second program-controlled valve and the third program-controlled valve are respectively fixedly mounted with a first manual ball valve and a second manual ball valve.

[0013] By adopting the above technical solution, when the first program-controlled valve, the second program-controlled valve and the third program-controlled valve need to be repaired, replaced or cleaned, the first manual ball valve and the second manual ball valve upstream can be closed to isolate the program-controlled valve and cut off the flow of the fluid. Closing the upstream ball valve can prevent the fluid from flowing into the program-controlled valve, and closing the downstream ball valve can prevent the fluid from flowing out of the program-controlled valve. This isolation function can ensure that no accidental fluid leakage or contamination occurs during the maintenance process, while protecting the safety of the staff.

[0014] In summary, the utility model has the following beneficial effects:

[0015] 1. The drainage process is automatically started according to the preset drainage cycle or real-time water level information. When condensed water is generated inside the gas dryer, the automatic drainage device will drain the condensed water. This avoids the energy waste caused by gas leakage in the traditional drainage method, achieves zero gas consumption drainage, improves drainage speed and efficiency, makes the production process smoother, and improves production efficiency;

[0016] 2. The water removed from the compressed air is discharged to the bottom of the inner cavity of the drainage liquid storage tank through the first connecting pipe. The water is filtered by the filter net and divided into upper and lower layers inside the first connecting pipe, so that the fourth connecting pipe and the second connecting pipe can discharge the clean water and turbid water in the upper and lower layers of the drainage liquid storage tank through two different pipes respectively. This makes it easier to handle the impurities in the water and ensures the smoothness of the pipeline drainage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] Embodiment 1:

[0022] refer to Figure 1 , Figure 2 , an energy-saving and environmentally friendly zero-gas consumption gas dryer drainage structure, including a gas-liquid separator 1, a drainage liquid storage tank 2 is arranged at the bottom of the gas-liquid separator 1, a first connecting pipe 3 fixedly connected to the bottom of the inner cavity of the drainage liquid storage tank 2 is fixedly connected to the bottom of the gas-liquid separator 1, a liquid level transmitter 4 and a magnetic flap liquid level gauge 5 are fixedly installed on both sides of the bottom of the gas-liquid separator 1, a second connecting pipe 6 is fixedly connected to the bottom of the drainage liquid storage tank 2, and a third connecting pipe 7 is fixedly connected to both sides of the second connecting pipe 6, and a first program-controlled valve 8 and a second program-controlled valve 9 are fixedly installed at one end of the two third connecting pipes 7 away from the second connecting pipe 6, and the first program-controlled valve 8 and the second program-controlled valve 9 are fixedly connected to the main drainage pipe 12 through a pipeline; the drainage process is automatically started according to a preset drainage cycle or real-time water level information. When condensed water is generated inside the gas dryer, the automatic drainage device will discharge the condensed water. This avoids the energy waste caused by gas leakage in traditional drainage methods, achieves zero gas consumption drainage, improves drainage speed and efficiency, makes the production process smoother, and improves production efficiency.

[0023] refer to Figure 1 , Figure 2 A first control circuit 10 and a second control circuit 11 are electrically connected between the liquid level transmitter 4 and the first program-controlled valve 8, and between the magnetic flap liquid level gauge 5 and the second program-controlled valve 9, respectively; they are used to convert the liquid level signals measured by the liquid level transmitter 4 and the magnetic flap liquid level gauge 5 into standard signal outputs, and control the first program-controlled valve 8 and the second program-controlled valve 9 to open or close.

[0024] Brief description of the usage process: The liquid level is continuously monitored through the drainage liquid storage tank 2, and the liquid level signal is converted into a standard signal output. It converts the measured liquid level signal, which is usually an analog signal, such as 4-20mA current or 0-10V voltage, into a standard signal output. This standard signal can be read by the control system and used for further processing or control. The first programmable valve 8 acts according to the signal output by the drainage liquid storage tank 2, such as opening or closing when the liquid level reaches or exceeds a preset value. This standard signal is transmitted to the control system through the first control line 10. The control system decides how to operate the first programmable valve 8 based on the received signal and the preset logic or algorithm. If the liquid level exceeds the upper limit, the control system will send a signal to open the first programmable valve 8 to discharge the liquid; on the contrary, if the liquid level is lower than the lower limit, the control system will close the first programmable valve 8 to prevent gas overflow;

[0025] At the same time, the magnetic flap level gauge 5 is used to provide direct visual indication and output electrical signals corresponding to the liquid level change, such as 4-20mA current signals or digital signals. The second control circuit 11 connects the magnetic flap level gauge 5 with the second program-controlled valve 9, and transmits the electrical signals output by the magnetic flap level gauge 5, which reflect the changes in the liquid level. The second program-controlled valve 9 automatically adjusts its opening according to the liquid level signal provided by the magnetic flap level gauge 5, thereby controlling the inflow or outflow of the liquid to keep the liquid level in the container within a set range. When the magnetic flap level gauge 5 detects a change in the liquid level in the container, it outputs an electrical signal corresponding to the change in the liquid level. This electrical signal is transmitted to the control unit of the second program-controlled valve 9 through the second control circuit 11. After receiving this signal, the control unit will calculate and adjust the opening of the program-controlled valve according to the preset control logic such as PID control. By adjusting the opening of the program-controlled valve, the inflow or outflow of the liquid can be controlled, thereby keeping the liquid level in the container within the desired range. Then, zero discharge is achieved, only water is discharged but not exhaust.
