Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 and figure 2 As shown, the dehydration device for the discharge chimney of the wet electrostatic precipitator of the present invention includes an upper casing 8 of the wet electrostatic precipitator, and a discharge chimney 1 is connected above the upper casing 8 . The exhaust chimney 1 is made of steel-lined resin flakes or fiberglass, which highly meets the requirements of the environmental assessment report. The inner wall of the discharge chimney 1 is evenly distributed with drip-catching and draining rods 2 along the circumferential direction, and the drip-catching and draining rods 2 are arranged along the longitudinal direction of the discharge chimney 1 . The drip-catching and drainage rod 2 is made of steel-lined resin scales or glass fiber reinforced plastics, and is uniformly welded on the inner wall of the discharge chi...

Abstract

The invention relates to a wet electric precipitator, in particular to a dehydration device for a wet electric precipitation outlet exhaust chimney. The device includes an upper shell of a wet electric precipitator, and an exhaust chimney is connected on the upper shell. The dehydration device is characterized in that: liquid catching drainage rods are uniformly distributed circumferentially on the inner wall of the exhaust chimney, and are arranged along the longitudinal direction of the exhaust chimney. A cyclone apparatus is disposed below the liquid catching drainage rods in the exhaust chimney. The dehydration device can effectively remove most moisture from the flue gas in the wet electric precipitation outlet exhaust chimney, also has the characteristics of simple structure and lowcost, does not generate running cost, and also has obvious effect on elimination of exhaust fume whiteness.

Description

technical field [0001] The invention relates to a wet electric dust collector, in particular to a dehydration device for a discharge chimney at the outlet of the wet electric dust collector. Background technique [0002] In recent years, due to the aggravation of smog weather, my country's SO for industries such as electric power, steel, chemical industry, non-ferrous smelting, and cement, etc. 2 The degree of emphasis and control on dust emissions has reached an unprecedented height. [0003] At present, the tail gas treatment of electric power, steel, chemical industry, non-ferrous smelting, cement and other industries has entered the stage of ultra-low emission. Among them, wet electrostatic precipitator is also widely used in the ultra-low emission treatment project of desulfurization tail. Due to the large investment of wet electrostatic precipitator, generally The design is based on the principle of economy and rationality. On the premise of ensuring that the emission...
