Description

Technical Field

[0001] The invention relates to the technical field of gas-liquid mixing, and in particular to a gas-liquid mixing air pump. Background Art

[0002] The fan is a device used for gas transportation. In the gas purification process, the fan is used to generate airflow so that the gas to be treated passes through the purification components in sequence for purification. Gas purification methods usually include gas-liquid mixing, that is, using liquid to mix with the gas to be treated to capture harmful substances in the gas to be treated or humidify the gas for subsequent purification. Traditional gas-liquid mixing usually uses a nozzle to atomize and spray the liquid, and the gas passes through the atomization spray area to achieve gas-liquid mixing. The liquid atomization methods include high-pressure injection, compressed air and liquid mixed injection, but these methods consume a lot of power. The dispersed particle size or atomization degree of the liquid directly affects the effect of gas-liquid mixing, and is also affected by the coverage range of the liquid atomization spray. The range of the atomization spray cannot fully cover the entire area where the gas passes, and there are dead corners where the gas and liquid cannot meet, resulting in poor gas-liquid mixing in the traditional method and limited gas purification effect. Summary of the invention

[0003] The technical problem to be solved and the technical task proposed by the present invention are to improve the existing technology and provide a gas-liquid mixing air pump to solve the problem that the gas-liquid mixing method in the current technology has poor mixing sufficiency and limited purification effect.

[0004] In order to solve the above technical problems, the technical solution of the present invention is:

[0005] A gas-liquid mixing air pump comprises a main body, blades and a liquid flow channel, wherein the blades are arranged at intervals on the main body along the rotation circumference and are used to discharge air radially, and the liquid flow channel is arranged at intervals on the main body along the rotation circumference, and the outlet of the liquid flow channel faces the radial outer side of the main body, and the inlet of the liquid flow channel is close to the radial inner side of the main body and is used to receive the liquid provided by the liquid supply pipe, and the liquid is centrifugally thrown out radially along the liquid flow channel. The gas-liquid mixing air pump of the present invention centrifugally throws gas and liquid out radially at the same time, and the liquid and gas collide and mix at the circumferential periphery of the main body. After the liquid and gas are mixed, they can play a role in cooling the gas. At the same time, the liquid is mixed with pollutants in the gas to be treated, which can effectively capture pollutants or humidify the gas for subsequent purification treatment. The liquid flows along the liquid flow channel and then centrifugally thrown out from the outlet of the liquid flow channel. Due to the high-speed rotation of the gas-liquid mixing air pump, the atomization degree of the liquid can be improved, and the liquid can be distributed more evenly in the circumferential direction, thereby improving the mixing uniformity and sufficiency of the gas and liquid, thereby improving the purification effect.

[0006] Furthermore, the aperture width of the liquid flow channel gradually decreases radially outward. According to the relationship between flow rate and flow velocity, when the flow rate is constant, the smaller the cross-sectional area, the faster the flow velocity. The inlet of the liquid flow channel on the radial inner side is wider, so it is convenient to fully receive the liquid. The outlet of the liquid flow channel on the radial outer side is smaller, which increases the speed at which the liquid is centrifuged out, and can enhance the collision and sputtering of the liquid in the liquid flow channel, improve the degree of atomization, so that the liquid thrown out from the outlet of the liquid flow channel can more evenly and fully collide and mix with the gas to be treated, thereby improving the adequacy of gas-liquid mixing.

[0007] Furthermore, the outlet of the liquid flow channel is in a slit shape, which can increase the speed at which the liquid is centrifugally thrown out, so that the liquid can be better impacted and mixed with the gas to be treated, thereby improving the completeness of gas-liquid mixing.

[0008] Furthermore, the edge of the slit-shaped outlet is also provided with a plurality of tooth-shaped protrusions, which have a dividing effect on the liquid ejected from the slit-shaped outlet, making the liquid more dispersed. The liquid ejected from the outlet collides with the tooth-shaped protrusions, thereby improving the atomization effect and thus improving the mixing adequacy of the liquid and the gas.

[0009] Furthermore, the main body is provided with a partition perpendicular to its rotation axis, and the liquid flow channel and the blades are respectively located on both sides of the partition. The partition is used to relatively separate the functional part of the centrifugal liquid and the functional part of the centrifugal gas, which can prevent the liquid from directly passing through the axial direction of the gas-liquid mixing air pump, and prevent the liquid from colliding with the gas to be treated in the central area of ​​the gas-liquid mixing air pump, so that the liquid cannot contact the gas-liquid mixing air pump and cannot be effectively centrifugally thrown out. The partition allows the liquid and the gas to be fully centrifugally thrown out respectively, and then collide and mix in the radial periphery of the gas-liquid mixing air pump, thereby improving the adequacy of gas-liquid mixing.

[0010] Furthermore, the main body is provided with a top plate layer parallel to the partition layer, and a plurality of flow channel blade plates connected between the top plate layer and the partition layer are provided, and the flow channel blade plates are distributed along the rotation circumference of the main body, and the liquid flow channel is formed by the area between two adjacent flow channel blade plates. The structure is simple, compact, easy to form, and can well ensure the effect of liquid centrifugal atomization.

[0011] Furthermore, the flow channel blade plate is separated from one of the flow channel blade plates on both sides thereof to form a liquid flow channel, and is spliced ​​together with the other flow channel blade plate at one end close to the radial inner side of the main body to form a sharp corner portion, so that the inlet width of the liquid flow channel is relatively large, and can fully receive the liquid provided by the liquid supply pipe, and play an effective role in collecting and guiding the liquid, thereby preventing part of the liquid from remaining in the radial center area of ​​the main body and failing to be effectively centrifugally thrown out.

[0012] Furthermore, the main body is provided with an inner guide hood located at the rotation center of the main body and an outer guide hood surrounding the inner guide hood. An air duct that turns from the axial direction to the radial outside is formed between the inner guide hood and the outer guide hood. Blades distributed along the rotation circumference are arranged between the inner guide hood and the outer guide hood, which can better enable the gas to be treated to enter the interior of the electrostatic unit of the cylindrical structure from the axial direction, and then pass through the electrostatic unit to the radial outside, thereby effectively improving the stability of the airflow.

[0013] Furthermore, it also includes an annular cover surrounding the circumference of the main body and spaced from the circumference of the main body, and a flow guide is formed between the annular cover and the main body. The gas and liquid centrifugally thrown out by the gas-liquid mixing air pump collide with the annular cover and are sputtered and dispersed, which can promote better uniform mixing of the gas and liquid, and form a gas-liquid mixing area similar to a water film in the flow guide, which can make the gas to be treated passing through the gas-liquid mixing area more fully mixed with the liquid to form a gas-liquid mixture, thereby improving the subsequent purification treatment effect.

[0014] Furthermore, a plurality of air guide vanes are arranged at circumferential intervals along the main body in the guide channel, and the air guide vanes are inclined to the rotation axis of the main body. The radially outward airflow generated by the rotation of the gas-liquid mixing air pump has a certain degree of rotation. When passing through the purification unit arranged on the radial periphery of the gas-liquid mixing air pump, there will be a large energy loss and a large air flow pressure drop, which reduces the purification efficiency and requires a large air supply power to ensure the normal operation of the equipment. The present invention utilizes air guide vanes to direct the airflow so that the airflow can pass through the purification unit vertically well, thereby reducing the loss of wind pressure and reducing the power required to ensure the normal operation of the gas purification device.

[0015] Compared with the prior art, the present invention has the advantages of:

[0016] The gas-liquid mixing air pump described in the present invention centrifugally throws the gas and liquid radially outward, and the liquid and gas collide and mix at the circumferential periphery of the main body. The liquid will fully collide and sputter into particles in the liquid flow channel, and then be sprayed out from the outlet of the liquid flow channel, which can improve the atomization degree of the liquid, and can make the liquid more evenly distributed in the circumferential direction, thereby improving the uniformity and sufficiency of mixing of gas and liquid, and effectively improving the purification effect.

[0027] Specifically, the main body is provided with a partition 2 perpendicular to its rotation axis, a liquid flow channel 1 is provided on the top side of the partition 2, and blades 3 for radial air outlet are provided on the lower side of the partition 2. The partition is used to relatively separate the functional part of the centrifugal liquid and the functional part of the centrifugal gas, so as to avoid the collision of the liquid and the gas to be treated in the central area of ​​the gas-liquid mixing air pump, thereby causing the liquid to be unable to contact the gas-liquid mixing air pump and thus unable to be effectively centrifugally thrown out. The partition allows the liquid and the gas to be treated to be fully centrifugally thrown out respectively, and then collide and mix in the radial periphery of the gas-liquid mixing air pump, thereby improving the adequacy of gas-liquid mixing.

[0028] Furthermore, the main body is provided with a top plate layer 4 located above the partition layer 2 and parallel to the partition layer 2, and a plurality of flow channel blade plates 5 connected therebetween are provided between the top plate layer 4 and the partition layer 2, and the flow channel blade plates 5 are distributed along the rotation circumference of the main body, and the liquid flow channel 1 is composed of the area between two adjacent flow channel blade plates 5; and the aperture width of the liquid flow channel 1 gradually decreases toward the radial outside, specifically, the flow channel blade plate 5 is a straight plate, the flow channel blade plate 5 is inclined to the radial direction, and the flow channel blade plate 5 is separated from one of the flow channel blade plates 5 on both sides thereof to form the liquid flow channel 1, and is spliced ​​with the other flow channel blade plate 5 at one end close to the radial inside of the main body to form The pointed corner prevents the liquid provided by the liquid supply pipe 12 from remaining in the central area of ​​the gas-liquid mixing air pump. The liquid flow channel 1 is a triangular area with a narrow width on the radial outer side and a wider width on the radial inner side, which can ensure the speed at which the liquid is centrifuged out; the outlet of the liquid flow channel 1 is in a slit shape, which can increase the speed at which the liquid is centrifugally thrown out, so that the liquid can better collide and mix with the gas to be treated, thereby improving the adequacy of gas-liquid mixing, and one of the flow channel blade plates 5 is also provided with a plurality of tooth-like protrusions 6 on the edge of the slit-shaped outlet.

The air guide plates 11 are inclined to the rotation axis of the main body. The airflow is guided by the air guide plates so that the airflow can pass through the purification unit vertically, thereby reducing the loss of wind pressure and the air supply power required for the normal operation of the equipment.
