Description

Technical Field

[0001] This application relates to the field of air purification technology, and more specifically, to a cyclone separator. Background Technology

[0002] In gas purification systems, cyclone separators are key equipment. Their working principle is based on the rotational motion caused by the tangential introduction of airflow, which causes solid particles with large inertial centrifugal force to be thrown towards the outer wall and separated, thus capturing dust particles with a diameter of 5 to 10 μm or larger in the gas.

[0003] However, existing cyclone separators typically have a low dust capture rate (<70%), which allows uncaptured particles to be discharged with the airflow, potentially polluting the environment or affecting subsequent processes. If a cyclone separator is used as a pretreatment device, the low capture rate can increase the burden on downstream equipment (such as filters) and may shorten their service life. Utility Model Content

[0034] Example 1

[0035] refer to Figures 1 to 3This application provides a cyclone separator, including: a cylinder 110, an inlet pipe 140, and an outlet pipe 150. The cylinder 110 has a top cover 120 and a bottom cover 130, and an inlet 111 is provided on the side of the cylinder 110. The inlet pipe 140 is connected to the inlet 111, and the radial direction of the inlet pipe 140 is perpendicular to the radial direction of the cylinder 110, for introducing airflow into the cylinder 110 so that the gas can rotate within the cylinder 110. The first port of the outlet pipe 150 is located inside the cylinder 110, and the second port of the outlet pipe 150 extends out of the cylinder 110 from the bottom cover 130. The second port is used to connect to a vacuum pump, and there is a gap between the first port and the top cover 120. After the airflow is introduced into the cylinder 110, it rotates within the cylinder 110. During this rotation, solid particles with significant inertial centrifugal force lose kinetic energy upon impacting the inner wall of the cylinder 110, thus being separated and falling to the bottom of the cylinder 110, achieving gas-solid separation. The separated airflow can then move upward along the outlet pipe 150, enter the outlet pipe 150 through its upper opening, and finally exit through its lower opening.

[0036] Optionally, both the top cover 120 and the bottom cover 130 are detachably connected to the cylinder 110, allowing the operator to observe and clean the separated particles by removing the top cover 120 and the bottom cover 130. Specifically, during use, the operator can remove the top cover 120 to observe the particle accumulation on the bottom cover 130 from the top opening of the cylinder 110. If too much particle accumulates, the operator can insert a vacuum cleaner into the cylinder 110 for suction, or the operator can disconnect the connection between the cylinder 110 and the bottom cover 130, then lift the cylinder 110 and use a vacuum cleaner to suction the particles accumulated on the bottom cover 130.

[0037] Optionally, the top and bottom ends of the cylinder 110 are respectively provided with claws 112, and the top cover 120 and bottom cover 130 are respectively installed at the top and bottom ends of the cylinder 110 via the claws 112. In specific settings, the claws 112 have open and closed states, and the operator can control the state of the claws 112 to install and remove the top cover 120 and the bottom cover 130.

[0038] Optionally, a handle 113 is provided on the side of the cylinder 110 so that the operator can lift the cylinder 110 by pulling the handle 113, which improves the convenience of operation. In a specific design, the handle 113 and the cylinder 110 can be an integral structure.

[0039] Optionally, a pressure relief valve 114 is provided on the side of the cylinder 110 so that the operator can first depressurize the cylinder 110 when cleaning particulate matter, thereby preventing the accumulated particulate matter from being dispersed into the air due to pressure changes.

[0040] Optionally, the air outlet 150 and the bottom cover 130 can be an integral structure.

[0041] Optionally, the cyclone separator also includes a gas enhancement component disposed within the cylinder 110. This component enhances the rotational momentum of the gas as it moves from the inlet 111 to the first pipe opening. By enhancing the rotational momentum, the centrifugal force is amplified, making it easier for particles to be thrown against the cylinder wall and deposited at the bottom of the cylinder 110, thus improving the particle capture rate. Simultaneously, when used as a pretreatment device, this cyclone separator can reduce the load on subsequent equipment and extend its service life. It should be understood that in specific implementations, a gap exists between the gas enhancement component and the outlet pipe 150 to allow for upward gas movement.

[0042] Optionally, the gas enhancement component includes a first guide plate 160 and a second guide plate 170. Both the first guide plate 160 and the second guide plate 170 are circumferentially disposed on the inner wall of the cylinder 110. The first guide plate 160 is located on the side of the air inlet 111 near the top cover 120, and the second guide plate 170 is located on the side of the air inlet 111 near the bottom cover 130. Specifically, both the first guide plate 160 and the second guide plate 170 are arc-shaped structures that fit against the inner wall of the cylinder 110, and a guide channel can be formed between them. In practical use, this guide channel can more accurately guide the incoming airflow into a tangential flow, ensuring that the airflow enters the separator at the optimal angle, thereby increasing the rotational momentum of the airflow. In addition, the gas enhancement component can also play a restrictive role, preventing the airflow entering the cylinder 110 from directly entering the outlet pipe 150, thus affecting the separation effect.

[0043] Optionally, the first guide plate 160 and the second guide plate 170 can be an integral structure with the cylinder 110.

[0044] Optionally, both the first guide plate 160 and the second guide plate 170 are flat plates. Specifically, flat guide plates have a simple structure, are easy to process and install, and help reduce manufacturing costs and complexity. Of course, in other embodiments, the first guide plate 160 and the second guide plate 170 can also be other types of plates, such as curved plates, spiral plates, etc.

[0045] Optionally, the lengths of the first guide plate 160 and / or the second guide plate 170 are less than the circumference of the cylinder 110. This arrangement facilitates the downward rotational movement of the gas. In this embodiment, the length of the first guide plate 160 is equal to half the circumference of the cylinder 110, and the length of the second guide plate 170 is less than half the circumference of the cylinder 110.

[0046] Optionally, a gap is provided between the second guide plate 170 and the air outlet pipe 150, which gradually increases in the direction away from the air inlet 111. This arrangement facilitates the downward fall of particles to the bottom of the cylinder 110 and prevents particles from accumulating on the second guide plate 170.

[0047] In some embodiments, the cyclone separator further includes a dust cover 180, which is fitted onto the outer wall of the outlet pipe 150. The dust cover 180 is used to cause particles in the rising airflow to collide and settle due to gravity. Specifically, the dust cover 180 is an annular structure fitted onto the outlet pipe 150. The dust cover 180 is located in the rising airflow path, causing the rising airflow to change direction during its ascent to bypass the dust cover 180 and continue moving. Particles in the airflow, due to inertia, cannot follow the airflow's change of direction in time and thus collide with the dust cover 180. After the collision, the particles lose kinetic energy and are separated, falling to the bottom of the cylinder 110. Therefore, by setting the dust cover 180, inertial separation of particles in the rising airflow can be achieved, thereby realizing secondary capture of particles and improving the particle capture rate.

[0048] Optionally, the dust cover 180 is fixedly connected to the inner wall of the cylinder 110. For example, the dust cover 180 can be fixedly connected to a sheet metal part on the inner wall of the cylinder 110, which can improve the stability of the dust cover 180 and prevent the dust cover 180 from moving up and down along the exhaust pipe 150 under the action of gas pressure. Of course, in other embodiments, the dust cover 180 can also be fixedly connected to other locations, such as the dust cover 180 can be fixedly connected to the lower surface of the top cover 120.

[0049] Optionally, the dust cover 180 is located between the top cover 120 and the gas strengthening assembly. For example, the dust cover 180 can be located at the upper opening of the outlet pipe 150. This arrangement prevents the airflow from interfering with the downward rotating airflow as it passes around the dust cover 180, thereby ensuring the stability of the rotational motion and avoiding unnecessary pressure drops. Simultaneously, it also prevents the rising airflow from carrying particles falling along the cylinder wall into the outlet pipe 150, thus reducing secondary entrainment.

[0050] Optionally, the width of the dust cover 180 (i.e., the difference between its outer and inner diameters) is greater than the gap between the gas enhancement assembly and the outlet pipe 150. This arrangement prevents airflow from passing directly through the outside of the dust cover, thereby allowing more particles to collide with the dust cover 180 and contributing to improved inertial separation.

[0051] Optionally, the cross-section of the dust cover 180 gradually decreases from the side near the bottom cover 130 to the side near the top cover 120. For example... Figure 2As shown, the dust cover 180 is funnel-shaped. This design allows the airflow to travel at a lower speed on the lower surface of the dust cover 180, making it easier for particulate matter to settle.

[0052] Example 2

[0053] refer to Figures 4 to 5 This application provides a cyclone separator. In this embodiment and Embodiment 1, there are components with the same name but different reference numerals. These components are essentially the same, and the different reference numerals are used to distinguish the different embodiments.

[0054] Specifically, the cyclone separator includes: a cylinder 110', an inlet pipe 140', an outlet pipe 150', and a gas enhancement assembly. The cylinder 110' has a top cover 120' and a bottom cover 130', and an inlet 111' is provided on the side of the cylinder 110'. The inlet pipe 140' is connected to the inlet 111', and the radial direction of the inlet pipe 140' is perpendicular to the radial direction of the cylinder 110', for introducing airflow into the cylinder 110', so that the gas can rotate within the cylinder 110'. The first port of the outlet pipe 150' is located inside the cylinder 110', and the second port of the outlet pipe 150' extends out of the cylinder 110' from the bottom cover 130'. The second port is used to connect to a vacuum pump, and there is a gap between the first port and the top cover 120'. The gas enhancement component is disposed inside the cylinder 110'. The gas enhancement component is used to enhance the rotational momentum of the gas as it moves from the inlet 111' to the first port.

[0055] Unlike Embodiment 1, the gas enhancement component in this embodiment uses a sleeve 160', which is fitted over the outlet pipe 150' and radially connected to the cylinder body 110'. One end of the sleeve 160' is located between the inlet 111' and the top cover 120', and the other end is located between the inlet 111' and the bottom cover 130'. This arrangement forms an annular cavity between the sleeve 160' and the cylinder body 110', which increases the flow velocity of the gas entering it, thereby enhancing the rotational momentum and centrifugal force of the gas. This makes it easier for particulate matter to be thrown against the cylinder wall and deposited at the bottom of the cylinder body 110', thus improving the particulate matter capture rate. At the same time, the gas enhancement component also has a restrictive function, preventing the airflow entering the cylinder body 110' from directly entering the outlet pipe 150', which would affect the separation effect.

[0056] One or more embodiments in this specification are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this specification should be included within the protection scope of this application.

[0057] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
