Description

Technical Field

[0001] The utility model relates to the technical field of electric dust removal equipment, in particular to electric dust removal equipment with anti-corrosion function. Background Art

[0002] The electrostatic precipitator is a flue gas purification equipment. Its working principle is: when the dust particles in the flue gas pass through the high-voltage electrostatic field, they collide with the positive and negative ions and electrons between the electrodes and become charged (or charged during the ion diffusion movement). The dust particles carrying electrons and ions move toward the opposite electrodes under the action of the electric field force and accumulate on the opposite electrodes. The dust on the electrodes is made to fall into the collecting ash hopper through vibration and other methods, so that the flue gas passing through the electrostatic precipitator is purified, achieving the purpose of protecting the atmosphere and the environment. The electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove the particulate dust in the flue gas emitted by stoves or oil-fired boilers, thereby greatly reducing the amount of dust discharged into the atmosphere. It is an important environmental protection equipment to improve environmental pollution and improve air quality.

[0003] The existing patent (publication number: CN203935908U) discloses a wet electrostatic precipitator. The utility model discloses a wet electrostatic precipitator, including a shell and an electrostatic precipitator assembly arranged in the shell. A smoke outlet is provided at the top of the shell, and a smoke inlet is provided at the bottom of the shell. The shell is columnar, and the shell is divided into a purification section, a connecting section and a dust removal section which are connected in sequence. The electrostatic precipitator assembly is installed in the dust removal section, and the flue gas purification assembly is installed in the purification section. The flue gas purification assembly includes a shell, an opening at the lower end of the shell to form an air inlet, and an opening at the upper end of the shell to form an air outlet. A plurality of partitions and ultraviolet lamps are arranged in the shell, and at least one ultraviolet lamp is provided on one side of each partition. Nano photocatalyst materials are arranged on each partition, and the flue gas entering from the air inlet flows through each partition and is discharged from the air outlet. In the process of realizing the utility model, the inventor found that the prior art has the following problems:

[0004] 1. Most of the flue gas discharged from combustion is at a high temperature. A large amount of high-temperature flue gas directly flows into the flue gas inlet and contacts the electrostatic precipitator components. The flue gas temperature is high, and the internal electrodes are directly in contact with the high-temperature flue gas. After long-term work, the circuit is prone to aging and damage;

[0005] 2. In order to prevent dust accumulation in the internal flue gas purification components, the air inlet chamber and the air outlet chamber will be cleaned through a flushing device. However, after flushing, water marks will remain on the inner wall and the internal dust removal components. The water marks cannot be cleaned up, which will cause corrosion to the internal dust removal components. Utility Model Content
