[0002] In the field of industrial production, such as machinery manufacturing, chemical industry, electronics, etc., compressed air is generally needed. The air is compressed by an air compressor, and then the compressed air is transported to the terminal gas-using equipment for production and processing. During the air compression process, the water vapor in the air is also compressed. During the transportation process, the compressed air will cool down, and the water vapor in it will condense into water due to supersaturation, and enter the terminal gas-using equipment together with the compressed air transported at high speed, thereby causing different degrees of rust and other destructive effects on the equipment. Therefore, after being compressed by the air compressor, the air needs to be dried by a dryer and finally stored in a gas tank. The dryer requires high-power electric energy to drive, and it is easy to fail, causing production stagnation. It requires regular maintenance by professionals, resulting in high costs.

[0029] Figure 1 It is a schematic diagram of the structure of an embodiment of the utility model, referring to Figure 1 One embodiment of the utility model provides a compressed air dehydration device for dehydrating and drying the compressed gas for subsequent production and manufacturing.

[0030] Furthermore, the compressed air dehydration device of the utility model includes an air compressor 100. The air compressor 100 is responsible for pressurizing the gas, and during the heating process, the temperature of the gas will rise accordingly.

[0031] Furthermore, the air compressor output side of the air compressor 100 is connected to a compression tank group module, and the compression tank group module includes a plurality of compression tanks 200 connected in series, and the compression tank output side of the previous compression tank 200 is connected to the compression tank input side of the next compression tank 200 through a pipeline, so that the gas compressed by the air compressor 100 is sequentially injected into each compression tank 200 for storage and cooling. The compression tank output side of the compression tank 200 is located on the upper side of the compression tank input side of the compression tank 200, so that the condensed water formed after the gas in the compression tank 200 is cooled will not be brought to the next compression tank 200, ensuring that the condensed water in each compression tank 200 can be processed separately, ensuring the dehydration efficiency.

[0032] Furthermore, a water outlet 210 is provided at the bottom of each compression tank body 200 , and a steam trap 300 is provided on the water outlet 210 , and condensed water in the compression tank body 200 is discharged through the steam trap 300 .

[0033] In the above process, a dryer is no longer needed for dehydration work, but it is equivalent to using the power of the compressed air itself to discharge the condensed water through the steam trap 300 to achieve the dehydration effect. The gas is processed by the multi-layer compression tank 200, which is sufficient to ensure that the gas dehydration effect meets the requirements without increasing energy consumption, saving energy and being environmentally friendly. This dehydration method has high efficiency and stable gas output. The utility model has a low failure rate, simple maintenance, and lower cost.

[0034] Some embodiments, see Figure 2 A lower air distribution plate 220 is provided on the lower inner wall of the compression tank body 200 , and air distribution holes are provided on the lower air distribution plate 220 , so that the gas injected from the input side can flow into the compression tank body 200 more evenly through the lower air distribution plate 220 .

[0035] In some embodiments, the lower air distribution plate 220 forms an annular plate structure around the lower inner wall of the compression tank 200, and the annular plate structure has a middle hole 223 around the water outlet, and an annular air distribution space is formed between the lower air distribution plate 220 and the inner wall of the compression tank 200, and the compressed air is guided into an annular airflow through the lower air distribution plate 220 and then distributed upward to the cavity of the compression tank 200. The middle hole 223 is equivalent to the outflow position of the water outlet 210, so that the condensed water will not be blocked by the lower air distribution plate 220.

[0036] In some embodiments, the lower air distribution plate 220 includes a first plate body 221 and a second plate body 222 of the lower air distribution plate. The first plate body 221 of the lower air distribution plate is connected to the side wall of the compression tank body 200, and the second plate body 222 of the lower air distribution plate is connected to the bottom wall of the compression tank body 200, so that the gas can flow into the compression tank body 200 more evenly.

[0037] In some embodiments, an upper buffer plate 230 is provided on the upper inner wall of the compression tank body 200, and a buffer hole is provided on the upper buffer plate 230. A buffer space is formed between the upper buffer plate 230 and the upper inner wall of the compression tank body 200, so that the gas in the compression tank body 200 is buffered by the buffer space of the upper buffer plate 230 before being output.

[0038] In some embodiments, a multi-layer water collecting plate 240 is disposed in the compression tank body 200 , and the water collecting plate 240 is connected to the side wall of the compression tank body 200 , so that the condensed water formed after the gas is cooled can form droplets on the water collecting plate 240 more quickly.

[0039] In some embodiments, the water collecting plate 240 is inclined toward the middle and lower side of the compression tank 200, so that the liquid condensed water is collected along the water collecting plate 240 under the action of gravity and drips at the middle water outlet 210 for discharge.

[0040] In some embodiments, each compression tank 200 is provided with a safety valve 250 to ensure that the internal pressure of each compression tank 200 will not be overloaded.

[0041] Some embodiments, see Figure 3The steam trap 300 has a steam trap air inlet 301, an inner cavity, and a steam trap air outlet 302. A main valve 310 is arranged in the inner cavity of the steam trap 300. The main valve 310 includes a valve body 311 and a piston body 312. The piston body 312 guides the valve body 311 to control the switch action of the steam trap 300 by piston movement. A pilot valve 320 and a return spring 330 are respectively arranged on both sides of the main valve 310. A damping channel is arranged between the pilot valve 320 and the main valve 310. The pilot valve 320, as a control mechanism for controlling the main valve 310, realizes the opening and closing action by being sensitive to the temperature of the water and gas medium at the outlet 210. When a part of the medium flowing through the main valve 310 reaches the pilot valve 320 along the damping channel, the pilot valve 320 is in an open state, the main valve 310 is opened, and the condensed water is discharged. With the continuous discharge of condensed water, the system temperature gradually increases. When the temperature rises to a predetermined value, the pilot valve 320 is closed, the main valve 310 is closed by the action of the return spring 330, and the steam trap 300 is also closed and stops discharging condensed water.

[0042] In this embodiment, the pilot valve 320 is optionally a bellows valve, that is, the steam trap 300 adopts the principle of a bellows steam trap. When the device of the utility model is started, cooling condensed water is injected into the steam trap 300, and the liquid in the bellows of the pilot valve 320 is in a condensed state. The valve core of the pilot valve 320 is in an open position under the elastic force of the spring built into the pilot valve 320. When the temperature of the condensed water gradually rises, the liquid in the bellows begins to evaporate and expand, the internal pressure increases, and the bellows deforms and elongates, driving the valve core of the pilot valve 320 to move in the closing direction. Before the condensed water reaches the saturation temperature, the steam trap begins to close and drives the steam trap 300 to close.
