Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, in particular to an anti-corrosion structure at the top of a dust collector. Background Art

[0002] Equipment that separates dust from flue gas is called a dust collector or dust removal equipment. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. At the same time, the price, operation and maintenance costs, service life, and ease of operation and management of the dust collector are also important factors to consider its performance. Dust collectors are commonly used facilities in boilers and industrial production.

[0003] The equipment in the electric heating plant needs a lot of fuel to generate heat during operation. The fuel will produce a lot of smoke during the combustion process. Therefore, dust collectors are often installed around boilers and other devices that require fuel to remove particles in the smoke and protect the environment. However, during the combustion of coal and other fuels, the smoke will contain more sulfur-containing substances. Since the shell of the current dust collector is made of metal and its interior is not treated with anti-corrosion, sulfur substances will corrode it from the inside of the dust collector shell, affecting the sealing of the dust collector, causing unfiltered harmful gases to leak from the damaged part of the dust collector.
