Description

Technical Field

[0001] This utility model relates to the field of cyclone separators, specifically a high-efficiency cyclone separator for fluidized bed reactors. Background Technology

[0002] A high-efficiency cyclone separator is a device that uses centrifugal force to achieve efficient gas-solid or liquid-solid separation. Dust-laden gas or a gas-liquid mixture enters the cyclone separator through a tangential inlet pipe, where it forms a high-speed rotating airflow within the cylinder. Due to centrifugal force, larger solid particles or droplets are thrown against the separator wall, forming a high-concentration layer of particles or droplets near the wall. Under the combined action of gravity and the downward movement of the airflow, these particles or droplets slide down the separator wall into the ash hopper, achieving separation from the gas phase. The separated gas phase forms an internal vortex in the central region and exits the separator upwards through the exhaust pipe.

[0003] Currently, existing technologies still have the following shortcomings:

[0004] Firstly, it has low separation efficiency for fine particles, which can easily lead to the loss of catalyst or product particles with the airflow.

[0005] Secondly, the separated particles accumulate at the bottom of the separator, requiring manual cleaning, which is cumbersome and prone to causing secondary pollution.

[0006] Third, it lacks an automatic cleaning function, and particles easily adhere to the inner wall after long-term use, affecting the separation effect.

[0007] Therefore, a high-efficiency cyclone separator for fluidized bed reactors is proposed to address the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] Please see Figures 1-5 As shown, a high-efficiency cyclone separator for a fluidized bed reactor includes a main body 1. An adsorption collection device 2 is provided at the bottom of the main body 1. The adsorption collection device 2 includes an adsorption cleaning component 3 and a pushing collection component 4. The adsorption cleaning component 3 includes an adsorption chamber 31 installed at the bottom of the main body 1. An anode coil 33 is fixedly installed in the inner cavity of the adsorption chamber 31. A cathode rod 34 is fixedly installed in the inner cavity of the adsorption chamber 31. A falling channel 38 is fixedly installed at the bottom of the adsorption chamber 31. The outer surfaces of the anode coil 33 and the cathode rod 34 are covered with an insulating sealing layer to prevent leakage and protect the electrodes.

[0029] During operation, the particulate-containing airflow enters the connecting chamber 11 through the air inlet 12 and is guided by the spiral guide vanes 15 in the separation chamber 14 to form a rotating airflow. Larger particles are thrown against the inner wall of the separation chamber and fall under the action of centrifugal force, while fine particles enter the adsorption chamber 31 with the airflow. In the adsorption chamber 31, the electric field formed by the cathode rod 34 and the anode coil 33 causes the fine particles to become charged and adsorbed on the surface of the anode coil 33.

[0030] Furthermore, the adsorption cleaning component 3 also includes a humidity monitor 36, which is fixedly installed on the outer surface of the adsorption chamber 31. Four support legs 32 are fixedly installed on the outer surface of the adsorption chamber 31.

[0031] During operation, the humidity monitor 36 monitors the humidity inside the adsorption chamber 31 in real time. When the humidity exceeds the threshold due to particle accumulation, the system automatically starts the cleaning program, and the support leg 32 ensures that the adsorption chamber 31 is stably installed.

[0032] Furthermore, a water supply pipe 37 is fixedly installed on one side of the adsorption chamber 31, and one end of the water supply pipe 37 is connected to the cleaning nozzle 35, which is fixedly installed on the outer surface of the adsorption chamber 31.

[0033] During operation, the water supply pipe 37 is connected to the cleaning solution, and the cleaning nozzle 35 sprays high-pressure cleaning solution onto the surface of the anode coil 33 to flush the adsorbed particles into the falling channel 38, thus preventing particle accumulation from affecting the separation efficiency.

[0034] Furthermore, the push collection component 4 includes a base 41, a conveying channel 42 is fixedly installed on the top of the base 41, the conveying channel 42 has a groove, and a sealing flange 45 is fixedly installed through the groove;

[0035] During operation, the particles in the falling channel 38 fall into the conveying channel 42. The sealing flange 45 is tightly connected to the conveying channel through the groove to ensure that there is no dust leakage during the particle conveying process and to avoid secondary pollution.

[0036] Furthermore, the push collection component 4 includes a stepper motor 43, which is fixedly installed on the top of the base 41. The output end of the stepper motor 43 is fixedly installed with a spiral auger blade 44, which is rotatably installed in the inner cavity of the conveying channel 42.

[0037] During operation, the stepper motor 43 drives the spiral auger blades 44 to rotate at a constant speed. The spiral pushes the particles in the conveying channel 42 to the collection device, eliminating the need for manual cleaning and reducing operational intensity.

[0038] Furthermore, the top of the sealing flange 45 is fixedly installed at the bottom of the falling channel 38;

[0039] During operation, the sealing flange 45 is sealed to the falling channel 38 by bolts, forming a detachable structure, which facilitates disassembly and cleaning of the inside of the conveying channel 42 during maintenance, while ensuring the sealing of the conveying process.

[0040] Furthermore, the main body 1 includes a connecting compartment 11, an air inlet 12 is fixedly installed on the top of the connecting compartment 11, and an air outlet 13 is fixedly installed on one side of the top of the connecting compartment 11.

[0041] During operation, the air inlet 12 receives the particulate-containing gas flow discharged from the fluidized bed reactor. The gas flow enters the separation chamber 14 through the connecting chamber 11. The purified gas is discharged from the outlet 13. The spiral guide vanes 15 in the separation chamber 14 initially separate larger particles, reducing the load on the adsorption chamber 31.

[0042] Furthermore, a separation chamber 14 is fixedly installed at the bottom of the connecting chamber 11, and a spiral guide vane 15 is fixedly installed in the inner cavity of the separation chamber 14.

[0043] During operation, the spiral guide vanes 15 are spirally distributed along the inner wall of the separation chamber 14, guiding the airflow to make circular motion. Under the action of centrifugal force, the particles move towards the chamber wall and fall down the wall to the adsorption chamber 31, realizing the initial separation of large particles and gas and improving the overall separation efficiency.

[0044] Working principle: The particulate-containing airflow enters the separator through the air inlet 12. First, it forms a swirling flow through the spiral guide vanes 15 in the separation chamber 14, using centrifugal force to separate large particles; fine particles enter the adsorption chamber 31 with the airflow, where they are further separated by electrostatic adsorption. When the humidity rises due to particle accumulation in the adsorption chamber, the humidity monitor 36 triggers the cleaning nozzle 35 to spray water for cleaning. The washed particles enter the conveying channel 42 through the falling channel 38 and are pushed to the collection device by the spiral auger blades 44.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
