Description

Technical Field

[0001] This utility model belongs to the field of air storage tank technology, specifically relating to an air storage tank device for an air compression system. Background Technology

[0002] An air receiver is a device used to store gas and also plays a role in stabilizing system pressure. When used in an air compression system, the air receiver is generally connected to the air compressor, and will be connected to equipment such as an oil separator, air filter, and air dryer to obtain clean compressed air. During operation, the high-temperature compressed air (70-100℃) generated by the air compressor enters the air receiver. The metal tank dissipates heat through natural convection, and the temperature drops to near the ambient temperature, causing water vapor to condense into liquid water and deposit at the bottom of the tank. However, the air receiver relies on natural cooling, which is not very effective in separating moisture from the compressed air. In addition, some air receivers cannot provide enough air residence time. The rapid passage of compressed air leads to insufficient cooling, and water vapor is carried away before it is completely condensed, which increases the load on the air filter and air dryer in the air compression system. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an air storage tank device for an air compression system to improve the air-water separation effect of compressed air.

[0004] Technical solution: To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An air storage tank device for an air compression system includes a first tank, a second tank connected to the first tank, and an axial flow fan connected to the second tank. The first tank is provided with a first inlet pipe and a first outlet pipe, and the second tank is provided with a second inlet pipe and a second outlet pipe. The second outlet pipe is connected to the first inlet pipe. The second inlet pipe is connected to the second tank along the tangential direction of the second tank. The second outlet pipe includes an inner extension pipe located inside the second tank and an outer extension pipe located outside the second tank. The inlet end of the axial flow fan faces the second tank.

[0006] Furthermore, the outer wall of the second tank is provided with heat dissipation fins, and the airflow at the inlet end of the axial flow fan passes through the heat dissipation fins.

[0007] Furthermore, the heat dissipation fins are arranged in a ring array on the outer wall of the second tank.

[0008] Furthermore, the outlet end of the axial flow fan faces the first tank.

[0009] Furthermore, the second tank is cylindrical and placed horizontally, the second exhaust pipe is connected to one end of the second tank, the length of the second tank is A, the length of the inner extension pipe is B, B≥0.25A, and the second intake pipe is connected to the end of the second tank near the second exhaust pipe.

[0010] Furthermore, the bottom of the first tank is connected to a first drain pipe, and a first drainer is connected to the first drain pipe; the bottom of the second tank is connected to a second drain pipe, and a second drainer is connected to the second drain pipe.

[0011] Furthermore, the bottom wall of the second tank is inclined, and the second drain pipe is connected to the lowest point of the bottom wall of the second tank.

[0012] Furthermore, the first tank body is provided with a first baffle corresponding to the first air inlet pipe.

[0013] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0014] 1. By connecting the second tank to the first tank, the residence time of the compressed air is extended. The second tank is used to generate a swirling flow in the air. Due to the density difference, the droplets are thrown against the inner wall of the second tank by centrifugal force and sink along the wall, thus achieving the separation of gas and droplets.

[0015] 2. An axial flow fan connected to the second tank is installed to increase the airflow velocity around the second tank. Heat dissipation fins are installed on the second tank, which has a good cooling effect, increases the cooling speed of the airflow, accelerates the condensation speed of water vapor in the airflow, and further improves the gas-water separation effect.

[0016] 3. The outlet end of the axial flow fan is oriented towards the first tank to accelerate the airflow around the first tank, increase the cooling speed of the first tank, accelerate the condensation of water vapor in the first tank, and reduce the load on the subsequent air filter and air dryer of the treatment tank.

[0017] 4. A first baffle is installed inside the first tank to reduce the disturbance of the laminar flow state inside the tank by the straight airflow. Attached Figure Description

[0022] The present invention will be further illustrated below with reference to specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0023] like Figure 1 As shown, an air storage tank device for an air compression system includes a first tank 1, a second tank 2, and an axial flow fan 3. The first tank 1 serves as the air storage tank. The middle part of the first tank 1 is cylindrical, with an upper end cap connected to the upper part and a lower end cap connected to the lower part. The first tank 1 is vertically arranged by multiple first support legs 19. The first tank 1 is provided with a first air inlet pipe 11 and a first air outlet pipe 12. The first air inlet pipe 11 is located on the outer circumferential side wall of the first tank 1 near the lower end, and the first air outlet pipe 12 is located on the outer circumferential side wall of the first tank 1 near the upper end. The first air inlet pipe 11 and the first air outlet pipe 12 are not on the same side. The bottom of the first tank 1 is connected to a first drain pipe 13, and the top of the first tank 1 is connected to a pressure relief pipe 14 and a pressure gauge 15. The pressure relief pipe 14 is provided with a safety valve. When the pressure inside the first tank 1 exceeds a set value, the safety valve automatically opens to release pressure. The pressure gauge 15 is used to display the pressure inside the first tank 1. The first tank 1 is equipped with a first baffle 16 corresponding to the first air inlet pipe 11. Since the straight airflow entering through the first air inlet pipe 11 will directly impact the tank wall of the first tank 1, it will disrupt the laminar flow state inside the first tank 1 and reduce the condensate collection efficiency. The first baffle 16 can guide the airflow downward and reduce the disruption of the laminar flow state inside the tank by the straight airflow.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, the second tank 2 is connected to the first tank 1. The second tank 2 is cylindrical and placed horizontally. The second tank 2 is horizontally positioned by multiple second support legs 29. The second tank 2 is equipped with a second air inlet pipe 21 and a second air outlet pipe 22. The second air inlet pipe 21 is vertically positioned and connected to the second tank 2 along the tangent direction of the second tank 2, so that the airflow entering the second tank 2 through the second air inlet pipe 21 forms a swirling flow inside the second tank 2. The second air outlet pipe 22 is connected to the middle of the right end of the second tank 2. The second air outlet pipe 22 includes an inner extension pipe 221 and an outer extension pipe 222. The inner extension pipe 221 is located inside the second tank 2 and is a straight pipe. The outer extension pipe 222 is located outside the second tank 2. The height of the second tank 2 is lower than the height of the first air inlet pipe 11. The outer extension pipe 222 extends upward and connects to the first air inlet pipe 11. The length from the inner wall of one end of the second tank 2 to the inner wall of the other end is A. The length of the section pipe 221 is B, where B ≥ 0.25A. In this embodiment, B = 0.5A. The second air inlet pipe 21 is connected to the end of the second tank 2 near the second air outlet pipe 22. In use, the second air inlet pipe 21 is connected to the air compressor. The airflow generated by the air compressor enters the second tank 2 through the second air inlet pipe 21 and forms a swirling flow inside the second tank 2. Since the airflow carries droplets, the droplets are thrown towards the inner wall of the second tank 2 due to the density difference and centrifugal force, and sink along the wall surface, achieving preliminary separation. After separation, the gas enters from the inlet of the inner extension section pipe 221 and finally enters the first tank 1 through the outer extension section pipe 222 and the first air inlet pipe 11. The bottom wall of the second tank 2 is inclined, and the height gradually decreases from the end where the second air outlet pipe 22 is located to the other end. The bottom of the second tank 2 is connected to the second drain pipe 24, which is connected to the lowest point of the bottom wall of the second tank 2. The separated liquid is discharged from the second drain pipe 24 into the second tank 2.

[0025] like Figure 1 , Figure 2 and Figure 4As shown, the axial flow fan 3 is connected to the second tank 2. The axial flow fan 3 is an existing duct-type axial flow fan, with its inlet facing the second tank 2. The inlet of the axial flow fan 3 is connected to one end of the second tank 2 via a connecting cylinder 31. When the axial flow fan 3 is working, the airflow at its inlet passes over the surface of the second tank 2, thereby cooling the second tank 2. The high-temperature airflow entering through the second air inlet pipe 21 accelerates water vapor condensation under the cooling effect of the second tank 2, improving the separation effect of moisture in the airflow. To improve the cooling rate of the second tank 2, heat dissipation fins 23 are provided on the outer wall of the second tank 2. The heat dissipation fins 23 are arranged in a ring array on the outer wall of the second tank 2. The airflow at the inlet of the axial flow fan 3 passes through the heat dissipation fins 23, which increases the heat exchange area of ​​the second tank 2 and accelerates the cooling rate of the airflow entering through the second air inlet pipe 21. The outlet end of the axial flow fan 3 faces the lower part of the first tank 1, thereby increasing the air flow rate around the first tank 1, improving the heat dissipation effect of the first tank 1, accelerating the condensation of water vapor in the gas in the first tank 1, and reducing the moisture in the gas inside the first tank 1. In order to improve the heat dissipation effect of the first tank 1, fins can also be installed on the outside of the first tank 1 to increase the heat dissipation area.

[0026] like Figure 1 As shown, a first drainer 4 is connected to the first drain pipe 13. The first drainer 4 is an existing automatic drainer, such as the YA-S6 automatic drainer produced by Chongqing Ri'an Valve Co., Ltd. It automatically drains accumulated water through an internal float ball and is equipped with a manual drain valve for easy manual drainage. A second drainer 5 is connected to the second drain pipe 24. The second drainer 5 is an existing float-type automatic drainer, such as the JAD20 float-type automatic drainer produced by Nanjing Qiaoke Air Compressor Equipment Co., Ltd. When the buoyancy of the drain is less than the weight of the drain float ball and the pressure applied by the compressed air, the drain outlet is closed; when the buoyancy is greater than the weight of the float ball and the pressure applied by the compressed air, the drain float ball rises and the drain outlet opens; when the condensate decreases, the drain outlet closes again, and the cycle continues.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
