Embodiment Construction

[0035] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.

[0036] like figure 1 As shown, the device includes a discharge electrode 1, a fixed anode 2, a first water spray cleaning device 3, and a second water spray cleaning device 4; the first water spray cleaning device 3 is installed on the discharge electrode 1 top, and the second water spray cleaning device 4 is installed on both sides of the fixed anode 2, and the fixed anode 2 is a cylinder or a plate.

[0037] like figure 1 As shown, in the continuously working self-cleaning wet electrostatic precipitator, multiple discharge electrodes 1 and fixed anodes 2 are arranged side by side at specified intervals; when in use, the device is installed on the upper part of the desulfurization tower or between the desulfurization tower and the chimney. It is used for further dust removal and acid removal of flue gas after desulfurization. The desul...

Abstract

The invention discloses a self-cleaning wet type electrostatic precipitation demister capable of working continuously. The electrostatic precipitation demister comprises discharge electrodes, fixed anodes, an atomizing device, a first water spraying washing device and a second water spraying washing device, wherein the first water spraying washing device is installed at the upper parts of the discharge electrodes, the second water spraying washing device is installed at two sides of the fixed anodes, the atomizing device is installed at a smoke inlet and is used for guaranteeing the humidity of smoke, and the water spraying washing devices enable a washing area to be powered off temporarily and a non-washing area to be powered normally for work according to the control sequence of an automatic program. The electrostatic precipitation demister can remove extra over 90% of dust (containing fine particulate matters), gypsum rain and acidic materials in the smoke without improving an existing deduster and desulfurizer, and can remove part of heavy metals in the smoke, the processed smoke satisfies the newest national environment protection standards, the requirement of a chimney on anticorrosion is lowered, a GGH(gas-gas heater) is omitted, and water, electricity and capitals are saved.

Description

technical field [0001] The invention relates to a flue gas treatment device, in particular to a continuous-working self-cleaning wet-type electrostatic precipitator and mist eliminator. Background technique [0002] my country is a big country in the production and use of industrial boilers. According to statistics, in 2008, there were more than 500,000 industrial boilers in use in my country, with a large number and wide distribution, of which more than 80% are coal-fired boilers; The flue gas contains a large amount of nitrogen oxides, sulfides and dust, which seriously pollutes the environment. The current national standard stipulates that the dust in the discharged coal-fired flue gas is ≤30㎎ / m 3 , nitrogen oxide content ≤ 80㎎ / m 3 , sulfide content ≤ 100㎎ / m 3 ;Because it is difficult to remove fine particles and dust with the current technology, there is no discharge requirement for the time being. The existing dry dust removal equipment, denitrification and desulfuriz...
