Description

Technical Field

[0001] This utility model belongs to the field of compressed air drying technology, and in particular relates to a compressed air dehumidification and drying tank. Background Technology

[0002] Compressed air is an important source of process gas and power energy, and is widely used in industries and departments such as petrochemicals, metallurgy, power, machinery, electronics, food, medicine, and defense. It is usually obtained by directly compressing air with an air compressor. This type of compressed air contains a large amount of moisture and needs to be dried before it can be used.

[0003] Existing compressed air drying and dehumidification methods include freeze drying and adsorption drying. Adsorption drying utilizes the pressure swing adsorption principle, using highly absorbent adsorbents such as alumina or molecular sieves filled inside an adsorption tower to dry compressed air. These devices are often dual-tower structures: one tower adsorbs compressed air at operating pressure, while the other tower undergoes a regeneration process after adsorption saturation. Adsorption drying and regeneration alternate between the two towers. Because of the use of two independent adsorption towers, the integration level is low, and the required floor space is large. Furthermore, the existing adsorption tower structure design is unreasonable, and changing the adsorbent is cumbersome. Utility Model Content

[0004] In view of this, in order to solve the above-mentioned technical problems, this utility model proposes a compressed air dehumidification and drying tank with a compact and centralized structure, small footprint, and easy maintenance and replacement of adsorbent.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A compressed air dehumidification and drying tank includes an upper tank, a transition tank, and a lower tank that are detachably connected from top to bottom;

[0007] The upper tank includes an upper tank body and a detachable tank lid located on the top of the upper tank body; the upper tank body is a cylindrical structure with open upper and lower ends, and its inner cavity is provided with a detachable adsorption component 1, the adsorption component 1 includes a cylinder body and an adsorbent filled in the cylinder body, and both the upper and lower ends of the cylinder body are filter screen structures; the tank lid is provided with an air outlet.

[0008] The transition tank is a cylindrical structure with open top and bottom ends. Its inner cavity is provided with a partition that divides the inner cavity into an upper region and a lower region that are not interconnected. The upper region is connected to the upper tank body. The side wall of the transition tank is provided with an air inlet and an air outlet corresponding to the upper region. The side wall of the transition tank is provided with an air outlet corresponding to the lower region.

[0009] The lower tank includes a lower tank body and a detachable tank vessel located at the bottom of the lower tank body; the lower tank body is connected to the lower region; the lower tank body is a cylindrical structure with open upper and lower ends, and its inner cavity is provided with a detachable adsorption component two with the same structure as the adsorption component one; the tank vessel is provided with an air inlet two and an air outlet two.

[0010] The upper tank, transition tank, and lower tank are stacked sequentially to reduce the floor space. Both the upper and lower tanks are adsorption tanks, and the transition tank connects the upper and lower tanks, serving as a link between them. All three are detachable. The adsorbent is concentrated in the cylinder and then placed in the upper (lower) tank for easy maintenance and replacement. The adsorption drying process is as follows: compressed air enters the upper or lower tank through inlet one / inlet two, is dehumidified and dried by the adsorbent, and is discharged through outlet one / outlet two. The regeneration process is as follows: when the adsorbent in the upper (or lower) tank is saturated, a portion of the dried gas discharged from the lower (or upper) tank is depressurized to atmospheric pressure and used as regeneration gas. It is sent into the upper (lower) tank through outlet one (outlet two) to purge and regenerate the adsorbent. The adsorbed moisture desorbs into the regeneration gas and is then discharged through vent one (vent two), completing the regeneration process. After cooling and purging, it can be used for drying and dehumidification again.

[0011] Furthermore, the can lid, the upper can body, the transition can, the lower can body, and the can vessel are all detachably connected by connecting ear plates with sealing gaskets and then locking them with bolts.

[0012] Furthermore, the cylinder includes an overlapping ring plate, a cylinder side wall plate arranged circumferentially along the inner edge of the overlapping ring plate, and filter screens disposed on the inner circle of the overlapping ring plate and the bottom of the cylinder side wall plate; the adsorbent is filled in the area enclosed by the cylinder side wall plate and the two filter screens; the overlapping ring plate overlaps the ear plate at the upper end of the upper tank, and then is connected to the ear plate of the tank cover and fixed by bolts.

[0013] The cylinder body is connected to the ear plate at the upper end of the upper tank body by overlapping ring plates, then connected to the tank cover, and finally fixed by bolts. The structure is simple and easy to disassemble and assemble. The adsorbent is concentrated in the cylinder body, which is convenient for later maintenance and replacement.

[0014] Furthermore, the inner cavity of the upper tank is provided with a first support ring plate, and the bottom end of the cylindrical side wall plate is supported on the first support ring plate; the inner cavity of the lower tank is provided with a second support ring plate, and the cylindrical structure inside the lower tank is the same as the cylindrical structure inside the upper tank, and is supported on the second support ring plate.

[0015] Furthermore, the air outlet ends of both the first air inlet and the second air inlet extend inward to the bottom of the cylinder and are provided with an air outlet plate; the upper end surface of the air outlet plate is an upwardly convex arc surface structure with multiple air outlet holes evenly distributed on it.

[0016] The air outlet plate design allows for more even air intake.

[0017] Furthermore, the filter screen at the bottom of the side wall of the cylinder is provided with an installation cavity recessed into the inner cavity of the cylinder; both the upper tank and the lower tank are provided with heat exchange components; the heat exchange components include a heat exchange coil one disposed in the installation cavity, a heat exchange coil two disposed around the outside of the side wall of the cylinder, a heat exchange inlet pipe connected to the inlet end of the heat exchange coil one and the heat exchange coil two, and a heat exchange outlet pipe connected to the outlet end of the heat exchange coil one and the heat exchange coil two; the side walls of the upper tank and the lower tank are provided with inlet pipe connection interfaces connected to their respective heat exchange inlet pipes and outlet pipe connection interfaces connected to their respective heat exchange outlet pipes.

[0018] Since the adsorbent releases a large amount of heat (heat of condensation) when adsorbing moisture in compressed air, the adsorbent temperature rise will reduce the adsorption efficiency; while the regeneration process requires the absorption of a large amount of heat (heat of vaporization), and the temperature drop will lead to an increase in the amount of regeneration gas required; therefore, a heat exchange component is set up to remove heat in time during adsorption and drying, and to replenish heat in time during regeneration.

[0019] Furthermore, it also includes an intake piping system and an exhaust piping system; the intake piping system includes an intake pipe with a valve connected to the inlet end of the intake port one, an intake pipe with a valve connected to the inlet end of the intake port two, and an intake manifold connected to the inlet ends of the intake pipe one and the intake pipe two; the exhaust piping system includes an exhaust pipe with a valve connected to the outlet end of the exhaust port one, an exhaust pipe with a valve connected to the outlet end of the exhaust port two, three parallel connecting pipes connected to the outlet ends of the exhaust pipe one and the exhaust pipe two, and an exhaust manifold connected to one of the connecting pipes; valves are provided on one side of the connecting pipes connected to the exhaust manifold on the side of the exhaust pipe one and the exhaust pipe two, and pressure regulating devices and valves are provided on the other two connecting pipes.

[0020] During adsorption drying, compressed air enters the upper tank (lower tank) through the main inlet pipe, inlet pipe 1 (inlet pipe 2), and inlet port 1 (inlet port 2). After passing through the adsorbent, it is discharged through outlet port 1 (outlet port 2), outlet pipe 1 (outlet pipe 2), a connecting pipe, and the main outlet pipe. During regeneration, a portion of the compressed air dried in the lower tank (upper tank) is depressurized through outlet pipe 2 (outlet pipe 1) and another connecting pipe (third connecting pipe) before entering outlet pipe 1 (outlet pipe 2) and outlet port 1 (outlet port 2) into the upper tank (lower tank). This purges and regenerates the saturated adsorbent. The adsorbed moisture desorbs into the regeneration gas and is then discharged through vent port 1 (vent port 2), completing the regeneration process.

[0021] Furthermore, it also includes a heat exchange inlet pipeline system and a heat exchange outlet pipeline system; the heat exchange inlet pipeline system includes a heat exchange inlet pipe 1 and a heat exchange inlet pipe 2, each connected to the inlet end of the two inlet pipe interfaces and equipped with valves, and a heat exchange inlet main pipe connected to the inlet ends of the heat exchange inlet pipe 1 and the heat exchange inlet pipe 2; the heat exchange outlet pipeline system includes a heat exchange outlet pipe 1 and a heat exchange outlet pipe 2, each connected to the outlet end of the two outlet pipe interfaces and equipped with valves, and a heat exchange outlet main pipe connected to the outlet ends of the heat exchange outlet pipe 1 and the heat exchange outlet pipe 2.

[0022] The heat exchange medium enters the heat exchange inlet pipe through the heat exchange inlet main pipe, heat exchange inlet pipe one (heat exchange inlet pipe two), and inlet pipe connection interface, and then enters heat exchange coil one and heat exchange coil two for heat exchange, and is discharged through the heat exchange outlet pipe, outlet pipe connection interface, heat exchange outlet pipe one (heat exchange outlet pipe two), and heat exchange outlet main pipe.

[0023] Compared with the prior art, the compressed air dehumidification and drying tank of this utility model has the following advantages:

[0024] (1) The compressed air dehumidification and drying tank of this utility model adopts the method of stacking the upper tank, the transition tank and the lower tank in sequence, integrating the two adsorption towers set in parallel and independently, with a compact and concentrated structure, reducing the floor space; the upper tank, the transition tank and the lower tank are detachable, and the adsorbent is concentratedly filled into the cylinder and then placed in the upper tank (lower tank) instead of being directly filled into the upper tank (lower tank), which facilitates later maintenance and replacement of the adsorbent;

[0025] (2) The compressed air dehumidification and drying tank of this utility model is equipped with a heat exchange component. The heat exchange component uses a method of surrounding the outside of the adsorbent and extending into the inside of the adsorbent to exchange heat. It can remove heat in time during the adsorption process and replenish heat in time during the regeneration process, thereby improving the adsorption and regeneration efficiency.
