Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a detachable oil mist removal device. Background Art

[0002] In waste gas treatment, waste gas pretreatment is crucial to the waste gas treatment effect, for example:

[0003] When using plasma or UV catalytic waste gas treatment processes, it is necessary to remove as much water mist, oil mist, and dust from the gas as possible. Water mist directly affects the treatment efficiency of these processes, while oil mist and dust will coat the surfaces of the UV lamp, catalyst, and ion tube, further affecting treatment efficiency.

[0004] When biological treatment processes are used to treat waste gas, the oil mist in the gas will cover and block the biological filler layer, affecting the formation of microorganisms and thus affecting the treatment efficiency of the system.

[0005] The conventional method to deal with the above problem is to add a demister, that is, to intercept the water mist and oil mist through a wire mesh demister. However, the demister will cause the water content and oil scale in the wire mesh to increase during long-term use, resulting in a decrease in the efficiency of intercepting water mist. Generally, the wire mesh demister is installed on the top of the tower or the top of the equipment, which is difficult to disassemble and cannot be cleaned or replaced all year round. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that the existing demister is large in size and difficult to replace and clean, and to propose a detachable oil mist removal device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A detachable oil mist removal device includes a demister cylinder, a universal cylinder and a connecting pipe. The left side of the demister cylinder is provided with a universal cylinder, a connecting pipe distributed horizontally is connected between the universal cylinder and the demister cylinder, the middle part of the right end of the demister cylinder is connected with a horizontally distributed disassembly port, the right end of the disassembly port is screwed and connected with a sealing screw cover, an annular demister is detachably installed between the disassembly port and the connecting pipe, the interior of the connecting pipe is fixedly connected with a limiting ring that fits with the annular demister, and the limiting ring has equal angles There are multiple groups of horizontally distributed soft iron cores fixedly connected, the left end of the soft iron core is wound with an energized coil, the left end of the limiting ring is equipped with a magnetic ring matching the soft iron core, the right end of the demister is located below the disassembly port and is equipped with a horizontally distributed servo motor, the left end of the servo motor is located inside the demister and is transmission-connected to a worm, the inside of the demister is located above the worm and is rotatably connected to a gear plate meshing with the worm, and the outside of the annular demister is provided with tooth grooves meshing with the gear plate.

[0011] As a further description of the above technical solution:

[0012] A manhole is installed at the bottom of the front end of the demister cylinder.

[0013] As a further description of the above technical solution:

[0014] The interior of the communicating pipe is located on the right side of the limiting ring and is rotatably connected to multiple sets of guide rollers in an annular array, and the outer walls of the multiple sets of guide rollers are in contact with the outer wall of the annular demister.

[0015] As a further description of the above technical solution:

[0016] Two sets of lifting handles are symmetrically fixedly connected to the left end of the annular demister.

[0017] As a further description of the above technical solution:

[0018] The cross section of the magnetic ring is an I-shaped structure, and the outer wall of the left end of the magnetic ring is in contact with the outer wall of the right end of the soft iron core.

[0019] As a further description of the above technical solution:

[0020] An air outlet for gas discharge is provided at the top of the front end of the universal cylinder.

[0021] As a further description of the above technical solution:

[0022] An electric control switch is installed at the bottom of the front end of the universal cylinder, and the output end of the electric control switch is electrically connected to the input end of the servo motor and the energized coil respectively.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0024] 1. In the present invention, an automatic insertion and removal structure is adopted. A servo motor, a worm and a gear plate are provided on the demister cylinder, and a tooth groove is provided on the annular demister. When the servo motor is energized, it can drive the worm to rotate continuously. Under the transmission action between the worm and the gear plate, the gear plate can rotate counterclockwise or clockwise. Under the transmission action between the gear plate and the tooth groove, the annular demister can move horizontally to the left or right in the demister cylinder. This structure can realize the automatic insertion and removal operation of the annular demister, reduce the workload of disassembly and processing of the annular demister, and improve the convenience of disassembly of the annular demister, thereby facilitating the daily installation, disassembly, maintenance, cleaning and use of the annular demister.

[0025] 2. In the present invention, a magnetic installation structure is adopted, and a limiting ring, a soft iron core and an energized coil are provided on the connecting pipe. At the same time, a magnetic ring is provided on the annular demister. When the annular demister slides horizontally between the connecting pipe, the demister cylinder and the disassembly port, the energized coil can be controlled to be energized, and the soft iron core will generate electromagnetic force. Under the action of the magnetic force, the magnetic ring on the annular demister will be magnetically attached to the soft iron core. At the same time, the annular demister will be stably attached to the limiting ring. This structure can stably limit the annular demister between the connecting pipe, the demister cylinder and the disassembly port, which not only improves the stability of the installation of the annular demister, but also improves the sealing effect between the annular demister and the demister cylinder.

[0026] 3. In the present invention, an external demisting structure is adopted. The whole device is composed of a universal cylinder, a connecting pipe and a demisting cylinder. At the same time, the overall structure is an H-shaped structure. The annular demister is horizontally located between the connecting pipe, the demisting cylinder and the disassembly port. During actual operation, the annular demister can be put in and removed through the disassembly port, which reduces the workload of the demisting device and thus improves the convenience and efficiency of the disassembly of the demisting device.

[0036] Specifically, such as Figure 1-3 As shown, the top of the demister 2 is connected to an air inlet 201 for gas to enter, and a manhole 5 is installed at the bottom of the front end of the demister 2. The setting of the air inlet 201 facilitates the exhaust gas that needs to be treated to enter the demister 2, and the setting of the manhole 5 facilitates the operator to enter and exit the demister 2 and the installation and maintenance of the internal components of the demister 2.

[0037] Specifically, such as Figure 2 and Figure 4As shown, the interior of the connecting pipe 3 is located on the right side of the limiting ring 301 and is rotatably connected to multiple sets of guide rollers 302 in an annular array, and the outer walls of the multiple sets of guide rollers 302 are in contact with the outer walls of the annular demister 8. The left end of the annular demister 8 is symmetrically fixed with two sets of lifting handles 802. The cross-section of the magnetic ring 801 is an "I"-shaped structure, and the outer wall of the left end of the magnetic ring 801 is in contact with the outer wall of the right end of the soft iron core 9. This structural setting improves the stability of the soft iron core 9 and the magnetic ring 801 after magnetic attraction, thereby reducing the shaking and offset of the annular demister 8 inside the demister cylinder 2. The setting of multiple sets of guide rollers 302 improves the stability of the sliding adjustment and installation of the annular demister 8 inside the connecting pipe 3.

The electric control switch 7 can be pressed to control the servo motor 6 to work. When the servo motor 6 is powered on, it can drive the worm 601 to rotate continuously. Under the transmission action between the worm 601 and the gear plate 11, the gear plate 11 will rotate counterclockwise. Under the transmission action between the gear plate 11 and the tooth groove 803 on the annular demister 8, the annular demister 8 will slide horizontally to the left into the demister cylinder 2. When the annular demister 8 completely slides between the connecting pipe 3, the demister cylinder 2 and the disassembly port 202, when the left end of the annular demister 8 contacts the limit ring 301, the electric control switch 7 can be pressed. The control coil 10 is energized. When the coil 10 is energized, the soft iron core 9 will generate electromagnetic force. Under the action of the magnetic force, the magnetic ring 801 on the annular demister 8 will be magnetically attached to the soft iron core 9. At this time, the annular demister 8 will be magnetically attached to the limit ring 301, and the sealing screw cover 4 can be screwed into the disassembly port 202, thus completing the installation and fixing of the annular demister 8. When the exhaust gas enters the demister cylinder 2 through the air inlet 201, the exhaust gas entering the demister cylinder 2 will move toward the middle of the annular demister 8 under the action of air flow. The annular demister 8 can process the exhaust gas. The treated exhaust gas will enter the universal cylinder 1 through the connecting pipe 3 under the action of the airflow, and be discharged through the air outlet 101 on the universal cylinder 1, thus completing the pretreatment of the exhaust gas.
