Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, and more specifically to a dust collector for thermal power generation. Background Art

[0002] A power plant, also known as a power station, is a factory that converts various primary energy sources stored in nature into electrical energy. A large amount of dust will be generated during the use of the coal-fired units in a thermal power plant. If it spreads into the air, it will cause serious dust pollution. Therefore, a good dust removal work in a thermal power plant is an important measure to achieve clean coal energy, and it is also an inevitable choice for the long-term development of the power system. At present, bag dust collectors are a kind of dust removal equipment that many large thermal power plants will choose. As we all know, bag dust collectors are a dry dust filtering device that is suitable for capturing fine, dry, non-fibrous dust. The bag is made of textile filter cloth or non-textile felt, and the dust-containing gas is filtered by the filtering effect of the fiber fabric. When the dust-containing gas enters the bag dust collector, the dust with large particles and high specific gravity settles down due to the action of gravity and falls into the ash hopper. When the gas containing finer dust passes through the bag, the dust is retained, so that the gas is purified.

[0003] It is found in the use of existing bag dust collectors that their bags need to be cleaned and replaced regularly. The removal of the bags is cumbersome, time-consuming and labor-intensive, which makes the subsequent maintenance workload large and reduces the service life of the device. Secondly, dust particles are not convenient for centralized collection and treatment. Therefore, we propose a dust collector for thermal power generation to solve the above problems.
