Description

Technical Field

[0001] The utility model relates to the technical field of cyclone separators, in particular to a cyclone rectifier. Background Art

[0002] The cyclone, also known as the cyclone separator, is used for gas-solid separation. The airflow enters tangentially, causing a rotational motion, so that the solid particles with greater inertia force are thrown off the wall, thereby achieving the effect of gas-solid separation.

[0003] Since the gas is constantly rotating, the resistance generated is also relatively large. The current method of reducing resistance is mostly to reduce the inlet wind speed. However, since the inlet wind speed is reduced, the rotation speed is also reduced, which will eventually lead to a decrease in the efficiency of gas-solid separation. Utility Model Content

[0008] Wherein, an air outlet is arranged above the inner cylinder, a material outlet is arranged below the straight cylinder, and a two-phase flow inlet is arranged on the side of the two-phase flow inlet pipe.

[0009] Wherein, the shape of the rectifying plate is a positive spiral shape and a reverse spiral shape.

[0016] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0017] The first embodiment of the present application is:

[0018] See also Figures 1 to 3 ,in, Figure 1 is a structural schematic diagram of a rectifier assembly in accordance with a first embodiment of the present invention. Figure 21 is a top view of the cyclone rectifier of the first embodiment of the utility model. Figure 3 It is a cross-sectional view of a cyclone rectifier of the first embodiment of the utility model. The utility model provides a cyclone rectifier, including an inner cylinder 101, a volute 106, a two-phase flow inlet pipe 107, a straight cylinder 108 and a rectifier assembly, wherein the rectifier assembly includes a mounting frame 102, a rotating seat 103, a rotating shaft 104 and a rectifier plate 105. The above-mentioned solution solves the problem that when the cyclone is used, the inlet wind speed is reduced, the rotation speed is also reduced, and the efficiency of gas-solid separation is finally reduced.

[0019] According to the present specific embodiment, the mounting frame 102 is fixedly connected to the inner cylinder 101 and is located at the top of the inner cylinder 101. The rotating seat 103 is fixedly connected to the mounting frame 102 and is located inside the inner cylinder 101. The rotating shaft 104 is rotatably connected to the rotating seat 103 and is located inside the inner cylinder 101. The number of the rectifying plates 105 is four. The four rectifying plates 105 are respectively fixedly connected to the rotating shaft 104 and are respectively located on the outside of the rotating shaft 104. The inner cylinder 101 is used to separate the two-phase flow of the material and the airflow. A damper is arranged inside the rotating seat 103 to prevent the rotating shaft 104 from rotating rapidly. The mounting frame 102 is the rotating seat. 103 and the rotating shaft 104 provide support, the rotating seat 103 and the rotating shaft 104 provide rotation support for the rectifying plate 105. When the two-phase flow of material and airflow is centrifugally separated, the two-phase flow of material and airflow enters from the two-phase flow inlet 111, and then rotates along the volute 106 part on the upper part of the cyclone. Due to the high density and large mass of the material, the material is thrown onto the side wall under the action of centrifugal force, and finally falls down along the side wall to the material outlet 110. The airflow passes through the block of the rectifying plate 105, so that the rotating wind moves in the vertical direction under the action of the rectifying plate 105, thereby reducing the resistance loss caused by the rotating wind in the subsequent pipeline.

[0020] Among them, the volute 106 is fixedly connected to the inner cylinder 101 and is located on the outside of the inner cylinder 101, the two-phase flow inlet pipe 107 is fixedly connected to the volute 106 and is located on the outside of the volute 106, the volute 106 is used to centrifugally separate the material and airflow of the two-phase flow, and the two-phase flow inlet pipe 107 is used to introduce the two-phase flow into the volute 106.

[0021] Secondly, the straight cylinder 108 is fixedly connected to the volute 106 and is located at the bottom of the volute 106. The straight cylinder 108 provides a guide for the falling materials, so that the falling materials slide along the inner wall of the straight cylinder 108 to the material outlet 110 and slide out of the cyclone.

[0022] Again, an air outlet 109 is provided above the inner cylinder 101, a material outlet 110 is provided below the straight cylinder 108, and a two-phase flow inlet 111 is provided on the side of the two-phase flow inlet pipe 107. The airflow flows out from the air outlet 109 after being blocked by the rectifying plate 105, and the material slides out from the material outlet 110 through the guide of the straight cylinder 108 after being separated in the volute 106, and the two-phase flow of the material and the airflow flows into the volute 106 from the two-phase flow inlet 111.

[0023] A cyclone rectifier of the present embodiment is used, wherein the inner cylinder 101 is used to separate the two-phase flow of material and airflow, a damper is arranged inside the rotating seat 103 to prevent the rotating shaft 104 from rotating rapidly, the mounting frame 102 provides support for the rotating seat 103 and the rotating shaft 104, and the rotating seat 103 and the rotating shaft 104 provide rotation support for the rectifier plate 105. When the two-phase flow of material and airflow is centrifugally separated, the two-phase flow of material and airflow enters from the two-phase flow inlet 111, and then moves along the cyclone. The volute 106 at the top of the cylinder rotates. Due to the high density and large mass of the material, the material is thrown onto the side wall under the action of centrifugal force, and finally falls down along the side wall to the material outlet 110. The airflow passes through the block of the rectifying plate 105, so that the rotating wind moves in the vertical direction under the action of the rectifying plate 105. In this way, the resistance loss caused by the rotating wind in the subsequent pipeline is reduced, which solves the problem that when the cyclone is used, the inlet wind speed is reduced and the rotation speed is also reduced, which eventually leads to a decrease in the efficiency of gas-solid separation.

[0024] The second embodiment of the present application is:

[0025] Based on the first embodiment.

[0026] According to this specific embodiment, the shape of the rectifying plate 105 is a positive spiral shape and a reverse spiral shape. The rectifying plates 105 of different shapes can respectively cope with various modes of two-phase flow separation, thereby improving the practicality of the cyclone rectifier.

[0027] By using a cyclone rectifier of the present embodiment, the rectifier plates 105 of different shapes can respectively cope with various modes of two-phase flow separation, thereby improving the practicality of the cyclone rectifier.
