Description

TECHNICAL FIELD

[0001] The utility model belongs to wastewater treatment technical field, concretely relates to a multistage cyclone reactor. BACKGROUND

[0002] The cyclone grit chamber is a device for sewage treatment, mainly used for removing inorganic particles with relatively large density and particle size, such as sand, gravel, etc. The cyclone grit chamber usually uses the principle of gravity sedimentation or centrifugal force separation to realize sand removal. Through the rotational movement of water flow in the device, sand particles are settled to the bottom of the device under the action of centrifugal force and gravity, and lighter organic matter is discharged with water flow.

[0003] The traditional single cyclone grit chamber has low sand removal efficiency, and the separation effect of fine particles (such as sand particles with particle size less than 0.2 mm) is poor, resulting in insufficient sand removal efficiency, and part of the sand particles are discharged with water flow. The single cyclone needs a higher water inlet pressure (usually 0.25-0.35 MPa) to maintain the cyclone effect, resulting in high energy consumption. The high-speed rotating water flow and sand particles cause serious wear to the inner wall of the cyclone, especially the inlet pipe and the cone part, increasing the equipment maintenance cost. In addition, the single cyclone is sensitive to the fluctuation of water flow and pressure, which easily leads to unstable sand removal effect. The single cyclone has limited treatment capacity, and multiple units are needed in large-scale application, which occupies a large area.

[0004] In order to improve the separation efficiency of fine sand and gravel, reduce energy consumption and operating cost, reduce equipment wear and tear, and prolong the service life, the present application provides a multistage cyclone reactor, which optimizes the structural design, reduces the occupied area, and improves the operation stability to adapt to the fluctuation of flow and pressure.

[0005] The information disclosed in this background section is intended only to increase an understanding of the general background of the present utility model and should not be construed as an acknowledgment or any form of suggestion that this information constitutes prior art with respect to the present utility model. CONTENT OF THE UTILITY MODEL

[0006] The utility model aims at providing a multistage cyclone reactor to solve the above technical problems.

[0017] Compared with the prior art, the multi-level rotational flow reactor has the following beneficial effects:

[0018] (1) The multi-level rotational flow reactor can gradually treat wastewater through a plurality of rotational flow units in series, and can enhance mixing and mass transfer through rotational flow to improve reaction efficiency, so that the solid particle separation effect in the wastewater is gradually enhanced.

[0024] The technical scheme of the utility model will be described clearly and completely below, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the skilled in the art without creative labor belong to the scope of protection of the utility model.

[0025] In the description of the utility model, it needs to be explained that, if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, it is only for the convenience of describing the utility model and simplifying the description, and it does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the utility model.

[0026] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, if the terms "mounting", "connecting", "connection" appear, they should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or the connection between two elements inside. For the skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0027] Referring to the drawings Figs. 1-2 A multi-stage cyclone reactor is formed by a plurality of cyclone units in series, adopts an automatic control system, monitors the water inlet pressure, flow and sand setting effect in real time, realizes intelligent operation, so as to ensure stable operation of the equipment and improve the sand setting efficiency. The multi-stage cyclone reactor specifically comprises:

[0028] The primary cyclone unit 1 is provided with a first water inlet at the top and a first water outlet at the bottom; one water pipe one 6 is connected at the first water inlet;

[0029] The secondary cyclone unit 2 is provided with a second water inlet at the bottom and a second water outlet at the middle; the first water outlet is communicated with the second water inlet through the water pipe two 7;

[0030] The tertiary cyclone unit 3 is provided with a third water inlet at the top and a third water outlet at the bottom; the second water outlet is communicated with the third water inlet through the water pipe three 8;

[0031] The fourth-stage vortex unit 4 has a fourth water inlet at the bottom and a fourth water outlet at the top; the fourth water inlet is connected to the third water outlet through a water pipe 9.

[0032] The pressure-stabilizing effluent device 5 is installed on top of the four-stage cyclone unit 4 and is used to regulate the effluent discharge. As a component within the multi-stage cyclone reactor, the pressure-stabilizing effluent device 5 can avoid excessive disturbance in the effluent discharge and prevent it from affecting the grit settling effect.

[0033] In this embodiment, the heights of the primary cyclone unit 1 and the secondary cyclone unit 2 are the same; the heights of the tertiary cyclone unit 3 and the quaternary cyclone unit 4 are also the same, and both are lower than the heights of the primary cyclone unit 1 and the secondary cyclone unit 2. Each of the primary cyclone unit 1, secondary cyclone unit 2, tertiary cyclone unit 3, and quaternary cyclone unit 4 has a mud discharge port at its bottom to collect and discharge the separated sand particles. The mud discharge port has good sealing to prevent sand backflow, and a conical sand collecting hopper and a sand discharge valve are used above it to ensure smooth discharge of sand particles.

[0034] Water pipe 6 is tangential to the outer wall of the first-stage cyclone unit 1; water pipe 7 is tangential to the outer walls of both the first-stage and second-stage cyclone units 1 and 2; water pipe 8 is tangential to the outer walls of both the second-stage and third-stage cyclone units 2 and 3; and water pipe 9 is tangential to the outer walls of both the third-stage and fourth-stage cyclone units 3 and 4. During wastewater treatment, the wastewater fluid enters each cyclone unit through a tangential inlet, forming a high-speed rotating flow field. In this rotating flow field, denser particles, such as solids or heavy liquids, are thrown towards the outer wall; less dense particles, such as gases or light liquids, accumulate towards the center. The multi-stage cyclone design separates sand particles from wastewater through swirling action, not only improving the separation efficiency of fine sand particles but also optimizing the inner wall material and structure of the hydrocyclone, reducing wear.

[0035] The inlet employs a low-pressure inlet design to evenly introduce wastewater into the cyclone separation unit. A flow equalization device ensures uniform water distribution, improving grit settling efficiency and reducing energy consumption. By adjusting the inlet's flow rate and pressure, the cyclone intensity and separation effect can be optimized, maintaining a stable flow field to ensure effective separation or reaction. Furthermore, the outlet discharges the separated clean water; a flow stabilization device reduces flow disturbance, improving effluent quality.

[0036] It should be noted that each stage of the multi-stage cyclone reactor further separates or reacts, and through step-by-step treatment, the separation or reaction effect gradually increases as the wastewater fluid passes through each stage. Multiphase separation and reaction are achieved by utilizing density differences and are suitable for liquid-liquid, gas-liquid, and solid-liquid separation. The enhanced mixing and mass transfer through cyclone flow helps to improve reaction efficiency.

[0037] This utility model's multi-stage cyclone reactor is an improved version of a traditional single-stage grit chamber, utilizing the cyclone effect for multiphase reaction or separation. Through multi-stage cyclone separation, low-pressure water inlet, and optimized structural design, it significantly improves grit removal efficiency, reduces energy consumption and equipment wear, and enhances operational stability. Achieving multiphase separation and reaction through the cyclone effect and centrifugal force, it is highly efficient, compact, and flexible, suitable for space-constrained applications. The number of stages and operating parameters can be adjusted according to requirements. Modular design and automated control system further enhance the equipment's applicability and economy, making it suitable for various wastewater treatment scenarios and widely applicable in chemical, environmental protection, and energy fields. It is highly practical and has broad application prospects.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
