[0024] See also Figure 1-Figure 5, a deep dehumidification air handling unit in an embodiment of the present invention comprises a shell assembly 1, the shell assembly 1 comprises a boost cylinder 101, a piston 102 and a drive rod 103, the boost cylinder 101 is slidably equipped with a piston 102, one end of the piston 102 is fixedly connected to the drive rod 103, and the drive rod 103 is slidably inserted on the boost cylinder 101; an air guide assembly 2, the air guide assembly 2 comprises an air guide cylinder 201, a first guide rod 202, a first blocking piece 203, a first push rod 204 and a first branch pipe 205, the two groups of air guide cylinders 201 are respectively arranged on both sides of the boost cylinder 101, and the air guide cylinder 201 is connected to the inner cavity of the boost cylinder 101, the first guide rod 202 is elastically limited and slidably arranged in the air guide cylinder 201, one end of the first guide rod 202 is fixedly provided with a first blocking piece 203, the first blocking piece 20 3 is used for slidingly blocking the inner cavity of the air guide cylinder 201, the other end of the first guide rod 202 is fixedly connected to the first push rod 204, and one side of the air guide cylinder 201 is also connected to the first branch pipe 205; a liquid guiding component 3, the liquid guiding component 3 includes a liquid guiding cylinder 301, a second guide rod 302, a second blocking piece 303, a second push rod 304 and a second branch pipe 305, the two groups of liquid guiding cylinders 301 are respectively arranged on both sides of the boosting cylinder 101, and the liquid guiding cylinder 301 is connected to the inner cavity of the boosting cylinder 101, the second guide rod 302 is elastically limited and slidably arranged in the liquid guiding cylinder 301, one end of the second guide rod 302 is fixedly provided with a second blocking piece 303, the second blocking piece 303 is used for slidingly blocking the inner cavity of the liquid guiding cylinder 301, the other end of the second guide rod 302 is fixedly connected to the second push rod 304, and one side of the liquid guiding cylinder 301 is also connected to the second branch pipe 305.

[0025] In actual application of this embodiment, when the treatment unit is used for air dehumidification, the air inlet pipe 104 on one side of the boost cylinder 101 is used to introduce the air to be treated into the inner cavity of the boost cylinder 101, and the drive rod 103 reciprocates under the drive of the external drive source, thereby driving the piston 102 to reciprocate. Since the piston 102 is slidably assembled on the inner wall side of the boost cylinder 101, the cavities at both ends of the piston 102 are in a state of alternating positive and negative pressure. The air guide cylinder 201 and the liquid guide cylinder 301 are respectively arranged at the cavities on both sides, and the air guide cylinder 201 is arranged on the top side of the boost cylinder 101. The liquid guide cylinder 301 is arranged at the bottom side of the boost cylinder 101. When any group of cavities is in a negative pressure state, the air to be processed is continuously sucked into the side cavity through the air inlet pipe 104, and the gas is filled in the cavity. When the side cavity is in a positive pressure state, the air guide cylinder 201 and the liquid guide cylinder 301 are respectively blocked by the first blocking piece 203 and the second blocking piece 303, so that the side cavity is in a state of continuous compression, and the pressure in the cavity is continuously increased. Continuous pressurization under isothermal conditions will reduce the moisture content in the air, that is, the water vapor in the air is liquefied, and when it contacts the inner cavity wall of the boost cylinder 101, it forms a The liquid droplets are formed into small droplets, which are then gathered to form large droplets, and continuously flow to one side of the liquid guide cylinder 301 under the action of gravity. Since there is a height difference between the bottom of the liquid guide cylinder 301 and the bottom of the booster cylinder 101, the droplets can flow into the liquid guide cylinder 301, and as the piston 102 continues to push, the droplets remaining on the inner wall of the cavity on this side can be scraped off by the piston 102, and finally converge to one side of the liquid guide cylinder 301. When the piston 102 is pressed against the first push rod 204 and the second push rod 304, the first push rod 204 and the second push rod 304 synchronously drive the first guide rod 204 to push the first guide rod 204 to push the second guide rod 3 ... 02 and the second guide rod 302 move, and when the first guide rod 202 and the second guide rod 302 slide after overcoming the elastic force, the first blocking piece 203 and the second blocking piece 303 thereon can be pushed toward the first branch pipe 205 and the second branch pipe 305 respectively, and when the first blocking piece 203 and the second blocking piece 303 slide through the first branch pipe 205 and the second branch pipe 305, the compressed air in the inner cavity of the booster cylinder 101 can be discharged through the first branch pipe 205, and the droplets formed in the inner cavity of the booster cylinder 101 can be discharged through the second branch pipe 305, so that the moisture in the humid air is separated and discharged.

[0026] See also Figure 2 In a preferred embodiment of the present invention, the shell assembly 1 also includes an intake pipe 104, a bypass pipe 105 and a one-way valve core 106. The intake pipe 104 is arranged outside the boost cylinder 101, and two groups of bypass pipes 105 are connected to the intake pipe 104. The bypass pipes 105 are respectively connected to both sides of the boost cylinder 101, and a one-way valve core 106 is also arranged on the bypass pipe 105.

[0027] In actual application of this embodiment, the air intake pipe 104 is used to introduce the air to be dehumidified into the boost cylinder 101, and the two groups of diverter pipes 105 are respectively arranged at both ends of the boost cylinder 101, and a one-way valve core 106 is arranged on the diverter pipe 105. The one-way valve core 106 is used to limit the air to enter the boost cylinder 101 along the air intake pipe 104 in one direction, so that when the cavity on one side of the boost cylinder 101 is in a positive pressure state, the diverter pipe 105 on this side is in a closed state, so as to limit the air in the cavity from flowing back to the air intake pipe 104 along the diverter pipe 105.

[0028] In one case of the present embodiment, when located at the same side, the distance between the first push rod 204 and the piston 102 is smaller than the distance between the second push rod 304 and the piston 102, so that the piston 102 preferentially contacts the first push rod 204, and therefore the first guide rod 202 preferentially pulls the first blocking piece 203 to slide to one end of the first branch pipe 205, at which time the compressed air in the cavity on this side will be quickly ejected through the first branch pipe 205, and when the pressure in the cavity returns to normal atmospheric pressure, the piston 102 pushes the second blocking piece 303 to move to the side of the second branch pipe 305, so that the droplets accumulated in the liquid guiding tube 301 flow naturally and are discharged along the second branch pipe 305, and when the piston 102 slides in the opposite direction, the first guide rod 202 and the second guide rod 302 both slide in the opposite direction under the elastic force, and seal the air guiding tube 201 and the liquid guiding tube 301 again.

[0029] See also Figure 5 In a preferred embodiment of the present invention, the deep dehumidification air handling unit also includes an air intake component 4, the air intake component 4 includes a cyclone separation cylinder 401 and an air bleed pipe 402, one end of the cyclone separation cylinder 401 is connected to the first branch pipe 205, and the other end of the cyclone separation cylinder 401 is connected to the air bleed pipe 402.

[0030] In actual application of this embodiment, the cyclone separation cylinder 401 is arranged on one side of the first branch pipe 205. When the compressed air in the inner cavity of the booster cylinder 101 is ejected along the first branch pipe 205, the air is ejected into the inner cavity of the cyclone separation cylinder 401 along the tangential direction of the cylinder body of the cyclone separation cylinder 401, and the remaining droplets are separated from the gas under the action of centrifugal force. The gas is discharged through the top of the cyclone separation cylinder 401, and the droplets gather to the bottom of the cyclone separation cylinder 401 under the action of gravity. A movable door plate can be set at the bottom of the cyclone separation cylinder 401 to discharge the liquid accumulated in the cyclone separation cylinder 401 at a regular time.

[0031] See also Figure 2In a preferred embodiment of the present embodiment, the deep dehumidification air handling unit also includes an adsorption component 5, the adsorption component 5 includes an adsorption shell 501, an adsorption chamber 502, a regeneration chamber 503 and a moisture absorption wheel 504, the adsorption shell 501 is arranged outside the booster cylinder 101, and the adsorption chamber 502 and the regeneration chamber 503 are independently arranged inside the adsorption shell 501, the air duct 402 is connected to one side of the adsorption chamber 502, and the moisture absorption wheel 504 is rotatably assembled between the adsorption chamber 502 and the regeneration chamber 503.

[0032] In actual application of this embodiment, the desiccant wheel 504 installed in the adsorption shell 501 is rotatably arranged between the adsorption chamber 502 and the regeneration chamber 503, and the air ejected from the cyclone separation cylinder 401 flows into the adsorption chamber 502 through the air duct 402, and is discharged to the outside of the adsorption shell 501 along the porous structure on the desiccant wheel 504, and the porous structure can absorb the residual moisture in the air again to keep the finally discharged air dry.

[0033] See also Figure 5 In a preferred embodiment of the present invention, the deep dehumidification air handling unit also includes a heat drying component 6, which includes a diverter 601, an air intake pipe 603, a heat drying machine 604 and an annular air guide groove 605. The diverter 601 is arranged on one side of the booster cylinder 101, and the air intake pipe 603 is connected to one side of the diverter 601. One end of the heat drying machine 604 is connected to the air intake pipe 603, and the other end of the heat drying machine 604 is arranged in the regeneration chamber 503. The two groups of annular air guide grooves 605 are respectively assembled at both ends of the booster cylinder 101, and the annular air guide grooves 605 are arranged in contact with the outer wall of the booster cylinder 101. Vents are arranged at both ends of the annular air guide grooves 605, and one group of vents is connected to the diverter 601.

[0034] In actual application of this embodiment, the hot dryer 604 continuously draws external air through the air intake pipe 603 on one side for heating, and sprays the high-temperature air into the regeneration chamber 503, so that the gas dries the moisture on it when passing through the moisture absorption wheel 504 and discharges it to the outside of the adsorption shell 501. Since the air intake pipe 603 needs to continuously draw air from the outside air, and the air will take away the heat on the surface of the object during the high-speed flow process, the annular air guide groove 605 arranged on the outer wall of the boost cylinder 101 is connected with the air intake pipe 603 through the diverter 601, so that the outside air can continuously absorb the heat on the shell of the boost cylinder 101 when flowing in the annular air guide groove 605. Since the temperature in the cavity will continue to rise under the boosted state, the annular air guide groove 605 can, on the one hand, reduce the temperature in the cavity of the boost cylinder 101 through the shell of the boost cylinder 101, so that the saturated absolute humidity of the humid air decreases with the decrease in temperature, and on the other hand, it can enable the water vapor to quickly condense into droplets when it encounters cold, thereby increasing the speed of gas-liquid separation.

[0035] In one case of the present embodiment, the hot drying component 6 also includes a sensing switch 602 and a trigger rod 606. The sensing switch 602 is arranged on the diverter 601, and is used to control the gas flow between the diverter 601 and the two groups of annular air guide grooves 605, and the two groups of annular air guide grooves 605 are in an alternating air guiding state. One end of the trigger rod 606 is assembled and connected with the driving rod 103, and the other end of the trigger rod 606 is slidably inserted in the sensing switch 602, and is used to control the opening and closing of the sensing switch 602, so that when the cavity on one side of the boosting cylinder 101 is in a boosting state, the annular air guide groove 605 on the outer wall side of the boosting cylinder 101 on this side is in a conducting state, so that the cold air can continuously cool down the shell of the boosting cylinder 101 on this side. Conversely, the humid air in the pressurized state can quickly separate the liquefied water droplets.

[0036] The above-mentioned embodiment of the present invention provides a deep dehumidification air handling unit, which is capable of quickly separating the liquid component in the humid air in the boosting state and quickly drying the air by cooperating with multiple dehumidification processes by arranging a reciprocating sliding piston 102 inside the boosting cylinder 101 and independently arranging an air guide component 2 and a liquid guide component 3 for exhausting gas and liquid on both sides of the boosting cylinder 101.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
