The air inlet preheating unit 100 can spray and heat the incoming gas and remove impurities from the gas. Then, the impurity removal unit 200 removes impurities from the spray water, facilitating the recycling of the spray water. Finally, the drying unit 300 dries the sprayed and heated gas.

[0033] Specifically, the air intake preheating unit 100 includes an air intake heater housing 101, an air intake port 102 disposed on the air intake heater housing 101, a water inlet 103 disposed on the air intake heater housing 101, and a spray assembly 104 disposed inside the air intake heater housing 101. The air intake heater housing 101 is also provided with a wire mesh demister 106 for demisting the gas after spray heating. The air intake heater housing 101 is cylindrical in shape. The air intake port 102 is disposed on one side of the air intake heater housing 101 near the bottom. The water inlet 103 is disposed at the upper end of the air intake heater housing 101. The top of the spray assembly 104 is connected to the water inlet 103. The spray assembly 104 can be an atomizing nozzle 104d.

[0034] Furthermore, the impurity removal unit 200 includes a filter screen 201 disposed inside the intake heater housing 101, a cleaning component 202 disposed on the filter screen 201, an impurity collection component 203 disposed below the filter screen 201, and a rapping component 204 disposed below the filter screen 201. The diameter of the filter screen 201 is the same as the inner diameter of the intake heater housing 101. The cleaning component 202 is used to clean the surface of the filter screen 201. It can be an electric push rod that drives the brush 202b to move and clean the surface of the filter screen 201. The impurity collection component 203 can be a collection box to collect impurities on the filter screen 201. The rapping component 204 is used to rappel the filter screen 201 and the impurity collection component 203, which is conducive to cleaning and collecting impurities.

The traction assembly 303 can traction the actuating assembly 302. The traction assembly 303 can be a cylinder. The sealing sleeve 304 can prevent gas leakage into the drying exhaust assembly 301.

[0036] Operation process: External gas can enter the air intake heater housing 101 through the air inlet 102. At the same time, heated intermediate water enters the air intake heater housing 101 and is sprayed by the spray assembly 104 to heat the gas. During spray heating, impurities carried in the gas can be removed and fall onto the filter screen 201. Simultaneously, the brush 202b driven by the electric push rod can be used to clean the surface of the filter screen 201. The impurities cleaned on the filter screen 201 can be collected by the collection box and discharged through the drain port at the bottom of the air intake heater housing 101. The sprayed and heated gas is demisted by the wire mesh demister 106 and discharged through the pipeline. It comes into full contact with the desiccant inside the pipeline. The cylinder drives the stirring rod to reciprocate, stirring the desiccant to make it evenly mixed and improve its utilization rate.

[0037] Example 2

[0038] Reference Figure 2 and Figure 3 As shown, this embodiment differs from the first embodiment in that: the spray assembly 104 includes a water inlet chamber 104a disposed inside the air inlet heater housing 101, a shaft 104b disposed at the lower end of the water inlet chamber 104a and communicating with the interior of the water inlet chamber 104a, a spray pipe 104c disposed on the shaft 104b, and a nozzle 104d disposed on the lower surface of the spray pipe 104c; wherein, the water inlet 103 communicates with the interior of the water inlet chamber 104a, the shaft 104b is rotatably mounted at the bottom end of the water inlet chamber 104a, and the shaft 104b has a cavity inside, through which water enters the inlet chamber. Several spray pipes 104c are provided in the cavity inside the shaft 104b. The spray pipes 104c are evenly arranged circumferentially on the shaft 104b and communicate with the inside of the shaft 104b. The spray pipes 104c are arranged in two staggered groups on the shaft 104b. The intermediate water that enters the water inlet chamber 104a enters the shaft 104b and is then distributed into the multiple spray pipes 104c. It is then evenly sprayed through the nozzles 104d, which allows the gas entering the air inlet heater housing 101 to fully contact the sprayed hot water and effectively heat the gas.

[0039] Specifically, the cleaning assembly 202 includes a cleaning rod 202a mounted on the shaft 104b, and a cleaning brush 202b mounted at the bottom of the cleaning rod 202a and in contact with the upper surface of the filter screen 201. One end of the cleaning rod 202a is fixedly connected to the shaft 104b, the filter screen 201 is disc-shaped, the length of the cleaning rod 202a is the same as the radius of the filter screen 201, and the cleaning brush 202b is fixedly mounted at the bottom of the cleaning rod 202a. The cleaning rod 202a can rotate with the shaft 104b and drive the cleaning brush 202b to clean the surface of the filter screen 201.

[0040] Furthermore, the impurity collection assembly 203 includes an opening 203a disposed on the filter screen plate 201, an impurity collection box 203b disposed below the opening 203a, an impurity discharge port 203c disposed on one side of the impurity collection box 203b, and a sealing cover 203d disposed at the impurity discharge port 203c. The opening 203a extends through the filter screen plate 201, and the impurity collection box 203b is disposed at the bottom of the filter screen plate 201. The bottom of the impurity collection box 203b is mesh-like, which facilitates... Water entering the collection box 203b is drained, and the bottom of the collection box 203b is inclined. The inclined slope of the collection box 203b can be used to collect impurities to one end of the collection box 203b. The discharge port 203c is opened on one side of the air inlet heater housing 101 and communicates with the inside of the collection box 203b. Impurities accumulated inside the collection box 203b can be discharged through the discharge port 203c. The sealing cover 203d can seal the discharge port 203c to prevent gas leakage.

[0041] Furthermore, the rapping assembly 204 includes a rapping rod 204a mounted on the shaft 104b, and a rubber block 204b mounted on the collection box 203b and intermittently in contact with the rapping rod 204a. One end of the rapping rod 204a is fixedly mounted on the shaft 104b. The shaft 104b can be rotated to drive the rapping rod 204a to rotate and intermittently contact the rubber block 204b, thereby rapping the rubber block 204b. This causes the collection box 203b to vibrate, and the vibration is transmitted to the filter screen 201. This allows impurities in the collection box 203b to slide down the slope under the action of vibration, while preventing impurities from clogging the filter screen 201.

[0042] The rest of the structure is the same as in Example 1.

[0043] Operation process: The heated intermediate water enters the inlet chamber 104a through the inlet 103 and then enters the cavity inside the shaft 104b. It is then distributed to several spray pipes 104c and sprayed evenly through the nozzles 104d. This ensures that the gas entering the air heater housing 101 comes into full contact with the sprayed hot water, effectively heating the gas. Impurities generated during spraying fall onto the filter screen 201. At this time, the shaft 104b rotates, driving the cleaning rod 202a to rotate. The cleaning brush 202b is fixedly installed at the bottom of the cleaning rod 202a. The cleaning rod 202a rotates with the shaft 104b, driving the cleaning brush 202b to clean the surface of the filter screen 201. Impurities are swept into the collection box 203b through the opening 203a. The shaft 104b can be rotated to drive the vibrating rod 204a to rotate and intermittently contact the rubber block 204b, thus vibrating the collection box 203b. The vibration is transmitted to the filter screen 201, causing the impurities in the collection box 203b to slide down the slope under the action of vibration. At the same time, it can prevent impurities from clogging the filter screen 201. The discharge port 203c is opened on one side of the air inlet heater housing 101 and communicates with the inside of the collection box 203b. Impurities accumulated inside the collection box 203b can be discharged through the discharge port 203c. The sealing cover 203d can seal the discharge port 203c to prevent gas leakage.

The drive gear 105c is fixedly installed on the rotating shaft 104b. The irregular rotating rod 105d is rotatably connected to the air inlet heater housing 101. The irregular rotating rod 105d is provided with a "U"-shaped frame. The "U"-shaped frame is integrated with the irregular rotating rod 105d. The diameter of the driven gear 105e is larger than the diameter of the drive gear 105c.

Plate 301d is slidably connected, and a spiral groove 302c-3 is provided on the sliding rod 302c. A guide rod 302c-4 is provided on the partition plate 301b. One end of the guide rod 302c-4 extends into the spiral groove 302c-3 through a ball bearing. When the sliding rod 302c moves, the spiral groove 302c-3 moves along the guide, thereby allowing the sliding rod 302c to rotate. A deflector blade 302c-2 is installed on the part of the sliding rod 302c located between the two fixed mesh plates 301d. The deflector blade 302c-2 can be used to agitate the desiccant particles inside the drying chamber 301c, thereby improving the utilization rate of the desiccant particles.

[0049] Furthermore, the partition plate 301b is provided with a sliding groove 301b-1, and one end of the sliding rod 302c is connected to a connecting rod 302c-1.

[0050] Furthermore, the traction assembly 303 includes a traction rod 303a disposed at one end of the sliding shaft 302b and connected to the irregular rotating rod 105d, a rotating disk 303b disposed at the bottom end of the irregular rotating rod 105d, a piston cylinder 303d disposed inside the intake heater housing 101, and a piston rod 303c disposed on the piston cylinder 303d and connected to the rotating disk 303b; one end of the traction rod 303a is hinged to the "U"-shaped frame on the irregular rotating rod 105d, and the other end of the traction rod 303a is hinged to the sliding shaft 302b extending into the intake heater housing 101; the piston cylinder 303d is fixedly installed inside the intake heater housing 101; the intake pipe of the piston cylinder 303d extends to the outside of the intake heater housing 101; the exhaust pipe of the piston cylinder 303d communicates with the interior of another drying chamber 301c; both the intake pipe and the exhaust pipe of the piston cylinder 303d are provided with one-way valves, and the flow directions of the two one-way valves are arranged in opposite directions.

[0051] The rest of the structure is the same as in Example 2.

[0052] Operation process: The intermediate water entering the water inlet chamber 104a will impact the worm gear 105a to rotate. At the same time, the rotating rod 105b is fixedly connected to the worm gear 105a. The rotating rod 105b is rotatably installed inside the water inlet chamber 104a. The other end of the rotating rod 105b extends into the shaft 104b and is fixedly connected to the shaft 104b. When the worm gear 105a rotates and drives the rotating rod 105b to rotate, the rotating rod 105b will synchronously drive the shaft 104b to rotate. The rotation of the shaft 104b can make the nozzle 104d rotate while spraying, which can make the spraying range wide.

[0053] After being sprayed and heated, the gas rises and passes through the wire mesh demister 106. Then, it enters one of the drying chambers 301c inside the tube 301a through the exhaust port and comes into full contact with the desiccant particles inside the drying chamber 301c. Finally, it is discharged into the gas turbine through the arc-shaped opening 203a on the connector.

[0054] While the shaft 104b rotates, it can drive the drive gear 105c to rotate. While the drive gear 105c rotates, it can mesh with the driven gear 105e to rotate synchronously, thereby causing the irregular rotating rod 105d to rotate. The rotation of the irregular rotating rod 105d can drive the traction rod 303a to reciprocate. The reciprocating motion of the traction rod 303a can drive the sliding shaft 302b to reciprocate. The reciprocating motion of the sliding shaft 302b can drive the sliding rod 302c to reciprocate through the connecting rod 302c-1. At the same time, the sliding rod 302c rotates under the action of the guide rod 302c-4, and drives the agitator 302c-2 to agitate the desiccant particles inside the drying chamber 301c. This can promote the mixing of desiccant particles and avoid excessive humidity difference between the two ends of the desiccant particles inside the drying chamber 301c during long-term drying, thus making the utilization rate of desiccant high.

[0055] While the irregular rotating rod 105b rotates, it can drive the rotating disk 303b to rotate. While the rotating disk 303b rotates, it can drive the piston rod 303c to reciprocate. While the piston rod 303c reciprocates, it can drive the piston plate to reciprocate. While the piston plate reciprocates, it can draw external gas into the piston cylinder 303d through the air inlet pipe. The piston plate moves to send the gas through the exhaust pipe into the drying chamber 301c, which is not connected to the inside of the air inlet heater housing 101. This blows the desiccant particles inside the drying chamber 301c, promotes its drying, and discharges the generated moisture through the vent 304c.

[0056] After a period of use, the tube body 301a can be rotated 180 degrees to change the position of the two drying chambers 301c. The piston cylinder 303d is used to reciprocate to deliver air to dry the desiccant particles inside one drying chamber 301c, and the desiccant particles inside the other drying chamber 301c are used to dry the heated gas. Continuous drying can be performed, which is convenient to use.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
