Description

Technical Field

[0001] The utility model belongs to the technical field of electrostatic tar precipitators, and particularly relates to a self-cleaning device for an electrostatic tar precipitator. Background Technique

[0002] An electrostatic tar precipitator refers to a device that uses the action of a high-voltage direct-current electric field to separate tar droplets and gas primary cooling equipment, and is a key device for gas purification and tar removal in a coking plant. When the electrostatic tar precipitator is working, all the ionized positive and negative ions fill the electric field between the corona electrode and the precipitation electrode. When impurity-containing gases such as tar droplets pass through this electric field, the impurities adsorbed with negative ions and electrons move to the precipitation electrode under the action of the Coulomb force of the electric field, release the charges carried, and are adsorbed on the precipitation electrode. When the amount of impurities adsorbed on the precipitation electrode increases until its weight is greater than its adhesion force, it will flow downward and finally be discharged from the bottom of the electrostatic tar precipitator, while the clean gas leaves from the upper part of the electrostatic tar precipitator, thereby achieving the purpose of purifying the gas.

[0003] According to a publicly disclosed electrostatic tar precipitator with a self-cleaning device (publication number: CN 218282136 U), which includes an electrostatic tar precipitator body and a filter box. A first motor is fixedly installed at the bottom of the electrostatic tar precipitator body. The output end of the first motor is fixedly connected to a second rotating shaft. A first support rod is fixedly installed on the outer side of the second rotating shaft. One side of the first support rod is rotatably connected to a first rotating shaft. A scraper is fixedly installed on the outer side of the first rotating shaft. A gear is fixedly installed at the upper end of the first rotating shaft. An internal gear ring is fixedly installed inside the electrostatic tar precipitator body and near the upper position. In the above application, by setting the first motor to control the rotation of the second rotating shaft, it is realized that the first rotating shaft moves along the inner wall of the electrostatic tar precipitator body while rotating, so as to use the scraper to scrape the impurities attached to the inner wall of the electrostatic tar precipitator body, improving the functionality of the device and achieving a self-cleaning effect. However, there are easily dead corners during cleaning in the above application, and the cleaning method is single, with poor practicability. Content of the Utility Model

[0008] Further, the number of the support legs is three. The motor is fixedly connected to the bottom of the electrocoking tar precipitator main body, and the support legs can effectively support the electrocoking tar precipitator main body.

[0009] Further, the cleaning plates are arranged inside the electrocoking tar precipitator main body, and the two cleaning plates are arranged symmetrically. The cleaning plates can effectively clean the inner wall of the electrocoking tar precipitator main body.

[0010] Further, the shape of the connecting rod is L-shaped, and the connecting rod is fixedly connected to both upper ends of the electric rotating rod. The connecting rod can effectively fix the elastic telescopic rod.

[0011] Further, the drag reduction device includes a drag reduction groove. A torsion spring rod is rotatably connected to the side of the drag reduction groove. A sealing plate is fixedly connected to the side of the torsion spring rod. The drag reduction device can effectively reduce the operating resistance of the motor.

[0012] Further, the drag reduction groove is opened on the cleaning plate. The number of the drag reduction grooves is set to two groups, and the number of each group of drag reduction grooves is set to three. The drag reduction grooves can effectively reduce the operating resistance of the motor.

[0013] Further, the torsion spring rod is rotatably connected to the cleaning plate, and the size of the sealing plate is adapted to the size of the drag reduction groove. The torsion spring rod can drive the sealing plate to return to its original position.

[0014] The utility model has the following beneficial effects:

The electric rotating rod will drive the connecting rod, the elastic telescopic rod and the knocking head to rotate. After the knocking head rotates to a fixed position, it will knock against the raised block to generate vibration, enhancing the cleaning effect, and the practicability is relatively strong.

[0016] By means of the drag reduction device, when the cleaning plate rotates for cleaning and the rotating resistance is too large, the torsion spring rod will drive the sealing plate to rotate and open under the action of the resistance, opening the drag reduction groove, which can effectively reduce the resistance of the electric rotating rod, prevent the motor from being damaged due to overload, and further enhance the practicability of the whole device.

[0030] The cleaning plates 43 are arranged inside the electrocatalytic tar precipitator main body 1. The two cleaning plates 43 are arranged symmetrically, and the cleaning plates 43 can effectively clean the inner wall of the electrocatalytic tar precipitator main body 1.
