Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cyclone separators, in particular to a cyclone separator for petrochemical production. Background Art
[0002] When the cyclone separator is in use, when the impurity-containing gas enters the cyclone separator at a high speed, it generates a strong rotation, and the airflow spirals downward along the cylinder into the cyclone cylinder, which is called an external vortex. The dense liquid droplets or dust particles are thrown toward the wall of the device under the action of centrifugal force, and fall along the cylinder wall under the action of gravity and flow out of the lower port of the cyclone cylinder. The rotating airflow contracts in the cylinder and flows toward the center, forming a secondary vortex upward and flowing out through the outlet pipe. This airflow is called an internal vortex. However, when the existing cyclone separator is performing gas separation, the side wall is subjected to a large impact force, resulting in severe wear and tear. It needs to be replaced after a period of use, but there is no early warning method for the wear and tear on the outer wall of the cyclone separator, which increases the material loss and has poor practicality.
[0003] In this solution, a cyclone separator for petrochemical production is therefore needed to improve the above problems. Utility Model Content

[0022] For examples, see Figure 1-3 , the utility model provides a technical solution:
[0023] A cyclone separator for petrochemical production comprises a cyclone cylinder 1, an air inlet pipe 2 is installed on the outer wall of the cyclone cylinder 1, a spiral blade 3 is installed on the inner wall of the cyclone cylinder 1, an air outlet pipe 4 is installed on the outer wall of the cyclone cylinder 1, a lower cylinder 5 is installed at the bottom of the cyclone cylinder 1, an outer shell 6 is installed on the outer wall of the lower cylinder 5, a connecting pipe 7 is installed on the outer wall of the outer shell 6, a fixing rod 8 is installed on the inner wall of the connecting pipe 7, a fan blade 9 is rotatably connected to the outer wall of the fixing rod 8, a collector 10 is installed at the port of the lower cylinder 5, and an ash hopper 11 is installed at the bottom end of the collector 10.
[0024] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The connection between the cyclone cylinder 1 and the air inlet pipe 2 is a connecting structure, the spiral blade 3 is located on one side of the air inlet pipe 2, the spiral blade 3 is located on one side of the air outlet pipe 4, the lower cylinder 5 is a conical structure, the connecting pipe 7 is located on one side of the lower cylinder 5, the connection between the connecting pipe 7 and the outer shell 6 is a connecting structure, the fixing rod 8 is located in the inner cavity of the connecting pipe 7, and the ash collecting hopper 11 is located directly below the cyclone cylinder 1 to facilitate dust collection.
[0025] The working process of the utility model is as follows: when the cyclone separator for petrochemical production designed by the present invention is working, an air inlet pipe 2 is installed on the outer wall of the cyclone cylinder 1, and a spiral blade 3 is installed on the inner wall of the cyclone cylinder 1. When the dust-laden airflow enters the cyclone cylinder 1 from the air inlet pipe 2, the airflow will change from linear motion to circular motion under the action of the spiral blade 3. Dust particles with a density greater than that of the gas will lose their inertia force when they contact the wall of the lower cylinder 5 and fall along the wall surface and enter the collector 10. When the rotating and descending external cyclone airflow reaches the bottom end of the conical structure lower cylinder 5, it moves toward the center of the cyclone cylinder 1 due to the contraction of the cone. When the airflow reaches a certain position at the lower end of the lower cylinder 5, it continues to flow in a spiral shape from the middle of the cyclone cylinder 1 from bottom to top in the same rotation direction. Finally, the purified gas is discharged from the device through the air outlet pipe 4. An outer shell 6 is installed on the outer wall of the lower cylinder 5, and a connecting pipe 7 is installed on the outer wall of the outer shell 6. , a fixing rod 8 is installed on the inner wall of the connecting pipe 7, and under the action of the fan blades 9 that are rotatably connected on the outer wall of the fixing rod 8, when the inner wall of the lower cylinder 5 is damaged by long-term impact, the inner wall of the lower cylinder 5 is broken, so that the airflow enters the inner wall of the outer shell 6 and the lower cylinder 5 to fill the cavity, and the connection between the connecting pipe 7 and the outer shell 6 is a connecting structure. The fixing rod 8 is located in the inner cavity of the connecting pipe 7, so that the airflow stays in the inner cavity of the connecting pipe 7, so that the airflow drives the fan blades 9 to rotate, so that the staff can observe the rotating fan blades 9 in time, which is convenient for timely maintenance and replacement, thereby helping to solve the problem that when the existing cyclone separator is performing gas separation, the side wall is subjected to a large impact force, resulting in serious wear and tear, and it needs to be replaced after a period of use, but there is no early warning method for the wear and tear on the outer wall of the cyclone separator, which increases the loss of materials and has poor practicality.
