Description
Technical Field
The utility model relates to a dust remover, concretely relates to use an electricity bag dust remover between treatment facility and intake stack.
Background
With the national economic development and the acceleration of the urbanization process, the energy structure mainly based on coal leads the emission of coal-fired flue gas in China to be continuously increased, and the pollution of fine particles is increasingly serious. Traditional dust removal technology is difficult to meet the emission requirement which is stricter day by day, and an electric dust remover, especially a wet-type electric dust remover, has the function of trapping fine particulate matters and fog drops in flue gas as a terminal fine treatment device of flue gas pollutants, and is gradually popularized and applied in the thermal power industry. The dust removal of the wet electric dust remover comprises three steps of charging, dust collection and dust removal, and the working principle is as follows: under the action of DC high voltage, the metal discharge electrode ionizes around it, so that the generated corona current flows to the dust collecting electrode, and if it contacts with dust particles or fog drops in the flue gas, it combines with them to form charged particles, which move to the dust collecting electrode under the action of Coulomb force in the electric field and flow out with continuous water film when moving to the surface of the dust collecting electrode.
SUMMERY OF THE UTILITY MODEL
Utility model purpose: in order to solve the defects of the prior art, the utility model provides an electric bag dust remover, its electric bag mixing region can improve filter bag life, strengthens the dust removal ability.
The utility model aims at realizing through such technical scheme, an electricity bag dust remover, including the casing, this casing left and right sides is equipped with air intake and air outlet respectively, and the bottom is equipped with the dust collecting opening, be equipped with electrode dust removal subassembly and cross the filter bag in the casing, electrode dust removal subassembly includes parallel arrangement's anode plate, the anode plate is arranged along the flue gas flow direction, and forms the wind channel each other, cross the filter bag and set up in the wind channel between the anode plate, also arrange along the flue gas flow direction.
Preferably, an air flow distribution plate is arranged in the air inlet.
Preferably, the upper end of the filter bag is fixed on a pattern plate of the dust remover through a connecting pipe.
Preferably, the filter bag is suspended directly from the faceplate of the dust collector.
Preferably, the filter bag is a metal filter bag.
Preferably, a pulse ash removal device is arranged on the filter bag.
Preferably, the pulse ash removal device comprises a compressed air bag and a plurality of blowing pipes, each blowing pipe corresponds to one air channel, the compressed air bag is communicated with each blowing pipe, a plurality of nozzles are arranged on the blowing pipes, each nozzle corresponds to one filter bag, and the nozzles are arranged at the opening positions of the filter bags.
Due to the adoption of the technical scheme, the electric bag dust collector disclosed by the utility model has the advantages of simple structure, ingenious design and good dust collection effect, charged dust passes through the parallel anode plates at a low speed, so that direct impact of high-speed dust-containing smoke on the filter bag is prevented, and the service life of the filter bag is prolonged; meanwhile, the flue gas introduced into the filter bag dust removal area is uniformly divided, so that the effective dust removal area of a cloth bag in the cloth bag dust removal area is increased, and the dust removal efficiency is improved.
