Description

Technical Field

[0001] The invention relates to the technical field of oil fume separation, in particular to an oil fume separation filter tower. Background Art

[0002] When the spheroidizing furnace performs heating annealing process on rods or wires, a common problem is that the oil attached to the surface of these materials will volatilize or incompletely burn during the high-temperature heating process, thereby generating a large amount of smoke. These fumes not only seriously deteriorate the air quality in the workshop and pose a threat to the health of workers, but also pollute the natural environment if they are directly discharged into the atmosphere without treatment.

[0003] In order to deal with this problem, a method commonly used in the industry is to use a water spray system to purify the flue gas. This system can effectively wash away the particulate matter in the flue gas and dissolve those substances that are soluble in water by spraying water mist into the flue gas. At the same time, the oil produced by incomplete combustion or volatilization in the flue gas will also cool and condense into particles after encountering water. However, if these condensates are not removed from the circulating water in time, not only will the water quality become turbid, but it will also significantly reduce the flushing effect of the water, thereby affecting the performance of the entire flue gas purification system.

[0004] Therefore, for systems that use water spraying to treat flue gas, it is crucial to regularly clean impurities and condensate in the circulating water. This can not only ensure the continued efficient operation of the system, but also protect the health of workers and the natural environment from pollution to the greatest extent possible.

[0005] According to a fume separation filter tower disclosed in Chinese patent announcement No. CN207270946U, the patent can purify the fume generated by heating a spheroidizing furnace, and separate the flushed and cooled oil from the circulating water, and the separated oil can be further utilized.

[0006] However, this patent only utilizes a simple spraying method to separate the oil fume, which cannot completely achieve the purpose of oil fume separation, resulting in oil stains still existing in the exhaust gas, causing environmental pollution.

[0007] Therefore, it is necessary to design a fume separation filter tower with strong practicality. Summary of the invention

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figure 1-6 The present invention provides a technical solution: an oil fume separation filter tower, characterized in that it includes: The tower body 1 is arranged longitudinally, the upper end and the lower end of the tower body 1 are arranged in a cone shape, and the middle part is arranged in a column shape; The outer wall of the upper end of the tower body 1 is connected to a smoke inlet pipe 2 for the oil smoke to enter. Here, the smoke inlet pipe 2 is arranged obliquely and directly opposite to the conical steel plate 78, so that the oil smoke can directly contact the conical steel plate 78 to form a liquid state. The outer wall of the lower end of the tower body 1 is connected to a second row of pipes 4, and the bottom of the tower body 1 is connected to a first row of pipes 3. A bracket 5 is fixedly installed on the outer wall of the lower end of the tower body 1. There are four brackets 5, which are evenly spaced and distributed on the outer wall of the tower body 1. The four brackets 5 installed outside the tower body 1 can provide a stable support for the tower body 1. The isolation cylinder 6 is fixedly mounted on the inner wall of the tower body 1, and the top surface of the isolation cylinder 6 is provided with multiple holes; A separation assembly 7 is arranged in the tower body 1; A spray assembly 8 is disposed in the tower body 1, and the spray assembly 8 is connected to the separation assembly 7; The scraping assembly 9 is installed between the inner wall of the tower body 1 and the separation assembly 7 .

[0027] The separation assembly 7 comprises: The motor 71 is arranged inside the tower body 1, and a connecting shaft 73 is fixedly installed at the output end of the motor 71; The connecting shaft 73 is fixedly connected to the auxiliary plate 75 through a T-shaped connecting pipe 82, and the auxiliary plate 75 is rotatably sleeved with a fixing plate 76, and the outer wall of the fixing plate 76 is fixedly installed with the inner wall of the tower body 1; The isolation cover 77 has an upper end fixedly mounted on the bottom surface of the auxiliary plate 75, and a lower end of the isolation cover 77 is rotatably connected to the upper end of the isolation cylinder 6; The outer wall of the isolation cover 77 has a porous arrangement; The conical steel plate 78 is arranged outside the isolation cover 77, and an elastic rubber ring 710 is arranged between the conical steel plate 78 and the isolation cover 77; Among them, the surface of the conical steel plate 78 has an outer groove 710, the edge of the outer groove 710 has a rounded corner, the interior of the conical steel plate 78 is hollow, and liquid nitrogen is injected to keep the conical steel plate 78 in a low-temperature state. Here, liquid will be produced when the oil smoke contacts the conical steel plate 78 in a low-temperature state. The internal principle of the range hood is adopted here.

[0028] In the specific implementation process, the connecting shaft 73 can be rotated by starting the motor 71, and the T-shaped connecting pipe 82 can be rotated when the connecting shaft 73 rotates, and then the auxiliary plate 75 and the isolation cover 77 are driven to rotate in turn. Since the conical steel plate 78 and the isolation cover 77 are connected by an elastic rubber ring 710, the conical steel plate 78 rotates with the isolation cover 77, so that the liquid generated when the oil smoke contacts the conical steel plate 78 in a low temperature state can be thrown out and quickly separated.

[0029] In this embodiment, a mounting plate 72 is fixedly installed at the bottom of the motor 71, the outer wall of the mounting plate 72 is fixedly installed to the inner wall of the isolation tube 6, and the top surface of the mounting plate 72 is provided with multiple holes. The mounting plate 72 can be used to stably install the motor 71, so that the motor 71 can work stably.

[0030] Furthermore, a spiral blade 74 is fixedly mounted on the outer wall of the connecting shaft 73. The spiral blade 74 can generate airflow when the connecting shaft 73 rotates, so as to introduce the oil smoke into the isolation cover 77 and the isolation cylinder 6, so as to facilitate the spraying treatment by the spray assembly 8.

[0031] Furthermore, the outer wall of the elastic rubber ring 710 is fixedly installed on the inner wall of the conical steel plate 78, and the inner wall of the elastic rubber ring 710 is fixedly installed on the outer wall of the isolation cover 77. The elastic rubber ring 710 can make the conical steel plate 78 vibrate slightly when it is under force, which can accelerate the rapid falling of the liquid formed by the contact between the oil smoke and the conical steel plate 78 in a low-temperature state.

[0032] Example 2: Based on the above embodiment, the spray assembly 8 includes: A straight connecting pipe 81, one end of which is connected to a water pump in a water tank (the water tank and the water pump are both chutes in the figure), and the other end of the straight connecting pipe 81 is rotatably arranged with the upper end of a T-shaped connecting pipe 82 through a bearing, and the outer wall of the T-shaped connecting pipe 82 is rotatably arranged with the tower body 1 through a bearing; The outer wall of the T-shaped connecting pipe 82 is fixedly mounted to the auxiliary plate 75, and the bottom of the middle part of the T-shaped connecting pipe 82 is fixedly mounted to the top of the connecting shaft 73; There are multiple nozzles 83 , which are evenly spaced and connected to the lower surface of the T-shaped connecting pipe 82 .

[0033] In the specific implementation process, the water in the water tank is pumped from the straight connecting pipe 81 into the T-shaped connecting pipe 82, and finally sprayed out from the nozzle 83 to spray the oil smoke treated by the separation component 7, thereby enhancing the separation purpose. When the connecting shaft 73 rotates, the T-shaped connecting pipe 82 can be rotated, and the nozzle 83 can be rotated 360 degrees, thereby increasing the spraying intensity.

[0034] Example 3: Based on the above embodiment, the scraping assembly 9 includes: The scraper rod 91 is disposed in the outer groove 79 but is not in contact with the inner wall of the outer groove 79; One end of the T-shaped column 92 is fixedly mounted on the surface of the scraper rod 91 , and the other end of the T-shaped column 92 is fixedly mounted with a spring 94 . One end of the spring 94 away from the T-shaped column 92 is fixedly mounted on the inner wall of the tower body 1 .

[0035] During the specific implementation process, since the scraper rod 91 is in the outer groove 79 and the T-shaped column 92 and the spring 94 are installed, the scraper rod 91 will be squeezed during the rotation of the conical steel plate 78, so that the scraper rod 91 is squeezed out and contacted with the surface of the conical steel plate 78, thereby realizing the scraping work. When the scraper rod 91 is located in the outer groove 79 again, the scraper rod 91 can vibrate under the action of the spring 94, and the oil stains on the surface can be shaken off for easy collection and treatment.

[0036] In this embodiment, a hollow column 93 is provided on the outer wall sliding sleeve of the T-shaped column 92, and one end of the hollow column 93 away from the scraper rod 91 is fixedly installed on the inner wall of the tower body 1. The hollow column 93 can limit the T-shaped column 92, so that the movement trajectory of the T-shaped column 92 is stable, and then the scraper rod 91 can work stably.

[0037] Working principle: First, the oil smoke will enter the tower body 1 from the smoke inlet pipe 2 and contact the conical steel plate 78 in a low-temperature state, forming liquid oil, and then achieving the purpose of oil smoke separation. The separated oil will fall through the porous position on the top surface of the isolation tube 6, and finally be discharged from the second row of pipes 4. Before this, start the motor 71 to rotate the connecting shaft 73. The spiral blade 74 can be rotated by rotating the connecting shaft 73, which can increase the suction force of the oil smoke. At the same time, the T-shaped connecting pipe 82 will also rotate to rotate the auxiliary plate 75. The isolation cover 77 can be rotated when the auxiliary plate 75 rotates. The rotation of the isolation cover 77 can make the elastic rubber ring 710 drive the conical steel plate 78 to rotate, forming centrifugal force, which can add oil and throw it out, thereby accelerating the discharge speed. During the rotation of the conical steel plate 78, it will be squeezed with the scraper rod 91, and the scraper rod 91 will be squeezed The scraper rod 91 is configured to be in contact with the surface of the conical steel plate 78 to achieve a scraping effect. At the same time, the scraper rod 91 and the outer groove 79 are configured, and the spring 94 is configured to achieve micro-vibration of the scraper rod 91, and the oil impurities attached to the surface of the scraper rod 91 are shaken off to avoid affecting the scraping effect. At the same time, the elastic rubber ring 710 can also achieve micro-vibration of the conical steel plate 78 to accelerate the falling speed of the liquid oil. When the oil smoke that has undergone a series of treatments enters the isolation cover 77 and the isolation cylinder 6 under the action of the spiral blade 74, the spray assembly 8 sprays it at this time, especially when the connecting shaft 73 rotates, the T-shaped connecting pipe 82 drives the nozzle 83 to rotate, thereby strengthening the spraying force and achieving a better separation effect. At this time, the water that has been sprayed is discharged through the first row of pipes 3, and finally the smoke of the treated oil smoke will also be discharged from the first row of pipes 3.
