Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of electrostatic precipitators, specifically a cleaning device for the precipitation electrode of an electrostatic precipitator. Background Technology
[0002] An electrostatic precipitator (ESP) is a primary cooling device for coke oven gas that uses a high-voltage direct current electric field to separate tar droplets from the gas. ESPs can be installed before or after the coke oven gas blower. Compared to mechanical tar removers, ESPs offer advantages such as higher tar removal efficiency, lower resistance loss, and larger gas throughput. They not only ensure the gas quality requirements of subsequent processes and improve product recovery rates but also significantly improve the operating environment.
[0003] According to electric field theory, positive ions are adsorbed onto the negatively charged corona electrode, and negative ions are adsorbed onto the positively charged precipitation electrode; all ionized positive and negative ions fill the entire space between the corona electrode and the precipitation electrode. When coal gas containing impurities such as tar droplets passes through this electric field, the impurities, which have adsorbed negative ions and electrons, move to the precipitation electrode under the influence of the Coulomb force of the electric field, release their charge, and are then adsorbed onto the precipitation electrode, thus achieving the purpose of purifying the gas, commonly referred to as the charging phenomenon. When the amount of impurities adsorbed on the precipitation electrode increases to exceed its adhesion force, it will automatically flow downwards and be discharged from the bottom of the electrostatic precipitator, while the clean gas leaves from the top of the electrostatic precipitator and enters the next process.
[0004] Of course, some impurities adsorbed on the inner wall of the precipitator will have a gravity less than their adhesion force and will not be able to flow down automatically. In order to ensure the normal operation of the electrostatic precipitator, the inner wall of the precipitator needs to be cleaned regularly. Since the pipes of the precipitator are long, it is extremely inconvenient for staff to clean it manually. Utility Model Content
[0005] To address the problems mentioned above, this utility model provides a cleaning device for the precipitation electrode of an electrostatic precipitator. When cleaning the precipitation electrode, the main frame is placed on top of the precipitation electrode, and the cleaning head is aligned with the pipe opening of the precipitation electrode. Then, a multi-stage telescopic rod drives the cleaning head downward into the pipe of the precipitation electrode, and the cleaning head cleans the impurities on the inner wall of the precipitation electrode. The operation is quick and convenient.
[0006] This utility model provides a cleaning device for the precipitation electrode of an electrostatic precipitator, including a main frame set on the top of the precipitation electrode, a multi-stage telescopic rod fixedly connected to the top of the main frame, the multi-stage telescopic rod extending downward, a through hole for the multi-stage telescopic rod to extend out at the bottom of the main frame, and a cleaning head provided at the bottom end of the multi-stage telescopic rod.
[0007] By adopting the above technical solution, when cleaning the precipitation electrode, the main frame is placed on top of the precipitation electrode, and the cleaning head is aligned with the pipe opening of the precipitation electrode. Then, the multi-stage telescopic rod drives the cleaning head downward into the pipe of the precipitation electrode, and the cleaning head cleans the impurities on the inner wall of the precipitation electrode. The operation is quick and convenient.
[0008] Furthermore, the bottom end of the cleaning head is angled inward to form a pointed tip.
[0009] By adopting the above technical solution, the bottom end of the cleaning head is made into a sharper and more pointed tip, which facilitates the cleaning of impurities on the inner wall of the precipitation electrode.
[0010] Furthermore, the cleaning head can be detachably mounted on the bottom of the multi-stage telescopic pole via an installation assembly.
[0011] By adopting the above technical solution, the cleaning head will wear out after long-term use. The detachable installation makes it easy to replace the cleaning head. Moreover, the structure of the precipitation electrode is available in various forms such as tubular and honeycomb, so a variety of cleaning heads can be prepared to suit the cleaning of different types of precipitation electrodes. The detachable installation also facilitates the replacement of different types of cleaning heads.
[0012] Furthermore, the installation assembly includes an installation cylinder, which is fixedly connected to the top of the cleaning head. The bottom end of the multi-stage telescopic rod is inserted into the installation cylinder, and an installation bolt passes between the installation cylinder and the multi-stage telescopic rod. An installation nut is threaded onto the installation bolt.
[0013] By adopting the above technical solution, when replacing the cleaning head, simply loosen the mounting nut and remove the mounting bolt to remove the mounting cylinder and cleaning head from the bottom of the multi-stage telescopic rod, replace the new cleaning head, and fix it with the mounting bolt and mounting nut. The operation is convenient.
[0014] Furthermore, a storage box is fixedly connected to the top of the main frame, and a lid is hinged to the storage box. A locking component for locking the lid is provided on the outer wall of the storage box.
[0015] By adopting the above technical solution, the storage box is used to hold different types of cleaning heads to prevent them from being lost. The storage box also has a lid, which is locked with a locking component to further prevent the cleaning heads from being lost.
[0016] Furthermore, the locking assembly includes two fixed plates, with a locking rod slidably passing between the two fixed plates. One end of the locking rod is fixedly connected to a pull ring, and a locking plate is fixedly connected to the cover. The locking plate is located at the end of the locking rod away from the pull ring, and a locking hole is opened in the locking plate. The locking rod is inserted into the locking hole, and a support ring is fixedly connected to the locking rod. The support ring is located between the two fixed plates, and a spring elastically supports the fixed plate near the pull ring and the support ring.
[0017] By adopting the above technical solution, when it is necessary to open the box cover, pull the pull ring. The pull ring will drive the locking rod to move away from the locking plate. When the locking rod disengages from the locking hole, the box cover can be opened to replace the cleaning head. After removing the cleaning head, close the box cover and release the pull ring. Under the elastic action of the spring, the locking rod will move towards the locking plate and insert into the locking hole to lock the box cover.
[0018] Furthermore, the storage box has multiple magnetic blocks inside for securing the cleaning head.
[0019] By adopting the above technical solution, the cleaning head can be magnetically attached to the storage box, improving the stability of the cleaning head and preventing it from being damaged by collisions inside the storage box.
[0020] Furthermore, both sides of the main frame are fixedly connected with lifting lugs.
[0021] By adopting the above technical solution, the electrostatic precipitator is usually quite high, requiring the cleaning device to be hoisted to the top of the precipitation electrode. The lifting lugs facilitate the hoisting of the cleaning device.
[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0023] (1) When cleaning the precipitation electrode, place the main frame on top of the precipitation electrode and align the cleaning head with the pipe opening of the precipitation electrode. Then, the multi-stage telescopic rod drives the cleaning head downward into the pipe of the precipitation electrode.

[0024] (2) The cleaning head will wear out after long-term use. The detachable installation makes it easy to replace the cleaning head. Moreover, the structure of the precipitation electrode is available in various forms such as tubular and honeycomb, so a variety of cleaning heads can be prepared to suit the cleaning of different types of precipitation electrodes. The detachable installation also makes it easy to replace different types of cleaning heads.
[0025] (3) Electrostatic precipitators are usually quite tall, so the cleaning device needs to be hoisted to the top of the precipitation electrode. The lifting lugs facilitate the hoisting of the cleaning device. Attached Figure Description

The operation is quick and convenient.
[0035] The bottom end of the cleaning head 4 is angled inward to form a sharp point. This sharp point at the bottom of the cleaning head 4 makes it easier to remove impurities from the inner wall of the sedimentation electrode.
[0036] The cleaning head 4 is detachably mounted on the bottom end of the multi-stage telescopic rod 2 via the mounting component 5.
