Description

Technical Field

[0001] This utility model relates to the field of electrostatic precipitator technology, and in particular to a novel electrostatic precipitator cathode ceramic shaft high-voltage heating and insulation box. Background Technology

[0002] Electrostatic precipitators (ESPs) face numerous challenges under complex smelting flue gas conditions, including flue gas intrusion into the cathode box leading to acid condensation, low secondary voltage and current, and frequent electric field tripping. These issues result in reduced dust collection efficiency and even power failure. Typically, due to the complex composition of smelting flue gas, including SO2 and dust content, flue gas temperature fluctuations, and other factors, the cathode insulation box is prone to ash accumulation and acid condensation during operation. This can easily lead to electric field tripping, high-voltage electric shock damage, low voltage and current operation, or even frequent electric field tripping, severely impacting the power supply rate and dust collection efficiency. Therefore, in production practice, frequent power outages for cleaning and replacement of the 95mm ceramic shaft are necessary to ensure normal equipment operation, significantly affecting dust collection efficiency and production costs.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] like Figure 1 As shown, this utility model provides a novel high-voltage heating and insulation box for electrostatic precipitator cathode ceramic shafts, comprising: a box body 1, which is used to isolate dust from the ceramic shaft; a hot air blowing device 2, which is installed on the upper part of the box body 1 and is used to clean the cathode insulating ceramic shaft; an electric heating device 3, which is installed on the side of the box body 1; and a sealing door 4, which is installed on the top of the box body 1.

[0022] The bottom of the hot air purging device housing 1 is inclined, and several baffles with the same inclination direction as the bottom of housing 1 are installed on the upper part of the inclined structure. The baffles can isolate the cathode insulating ceramic shaft to a certain extent and prevent the accumulation of smoke and dust. By optimizing the structure of housing 1, the secondary voltage of the electric field can be improved from 15-20KV to over 35KV, and the power supply rate of the electric field can be improved by 1%-1.5% compared with the same period last year.

[0023] Both outer side walls of housing 1 have protrusions in the middle. The electric heating device 3 of the hot air purging device is fixedly installed on the protrusions and the upper part of the side walls of housing 1. The electric heating device 3 of the hot air purging device is a heating box, and an electric heating component is installed inside the heating box. The electric heating component is used to heat housing 1. The electric heating component of the hot air purging device is a heating wire or an electric heating tube. The hot air purging device 2 includes a purging pipe connected to housing 1. The input end of the purging pipe is connected to a hot air blower, and the output end of the purging pipe passes through housing 1 and corresponds to the cathode insulating ceramic shaft inside housing 1.

[0024] The use of electric heating device 3 and hot air purging device 2 has solved the problem of frequent cracking caused by dust accumulation and condensation on the ceramic shaft of the electrostatic precipitator under complex high-temperature flue gas conditions. This has greatly improved the service life of the cathode ceramic shaft, increasing it from 4 months to more than 24 months. It has also reduced the consumption of 48 cathode ceramic basins per year, saving spare parts costs of RMB 96,000 per year. At the same time, it has reduced power outage accidents and cathode system failure rates, and improved dust collection efficiency by 0.7%.
