Embodiment Construction
[0014] Such as figure 1 with figure 2 As shown, the present invention provides a gas-solid two-phase shunt device for partly gas-suppressing dust at the tail of an electrostatic precipitator, including several component gas-suppressing devices installed side by side in the housing 6 between the tail of the final electric field and the horn-shaped outlet. The dust-gas-solid two-phase diversion device 1 is characterized in that: each group of the gas-distribution and dust-suppression gas-solid two-phase diversion device 1 is composed of purification units 2 and gas-distribution units 3 alternately arranged and coordinated, and each adjacent two groups The purification unit 2 and the gas distribution unit 3 on the gas-distributing and dust-suppressing trough-shaped pole plate 1 are respectively dislocated and arranged correspondingly, and each purification unit 2 is an independent flue gas purification chamber, and each purification unit 2 includes A groove-shaped dust suppress...

The invention relates to a gas-solid two-phase flow dividing device for gas separation and dust suppression of the tail portion of an electric dust remover. The gas-solid two-phase flow dividing device comprises multiple gas separation and dust suppression gas-solid two-phase flow dividing device bodies (1) installed between the tail portion of a last electric field and a horn-shaped outlet in a matched manner side by side. The gas-solid two-phase flow dividing device is characterized in that each gas separation and dust suppression gas-solid two-phase flow dividing device body (1) is formed by alternately arraying and matching a purification unit (2) and a gas separation unit (3); and the purification units (2) and the gas separation units (3) on every two adjacent gas separation and dust suppression groove-shaped pole plates (1) are correspondingly arranged in a staggered and matched manner. The gas-solid two-phase flow dividing device has the beneficial effects that the gas-solid two-phase flow dividing device is simple in structure; through the electric dust remover terminal dust suppression device for efficiently separating gas and dust, the efficiency of the electric dust remover is substantially improved, and a solution is provided for ultra-low emission of the electric dust remover; dust reentrainment is suppressed while the dust collection area is enlarged; the device consumes no electricity itself; separation of dust and gas is achieved according to the hydrodynamics theory; the space of the tail portion of the electric dust remover and the space inside the horn-shaped part of the outlet are sufficiently utilized; and the cost-performance ratio is high.
Description
technical field [0001] The invention relates to a dust collection device of an electric precipitator, in particular to a gas-solid two-phase flow splitting device for partly aerating and suppressing dust at the tail of the electric precipitator. Background technique [0002] With the improvement of environmental protection standards for dust emissions, high-efficiency electrostatic precipitators have to consider the impact of secondary dust caused by rapping on the emission concentration. The end of traditional electrostatic precipitators (the front of the outlet horn) generally adopts a double-layer misplaced groove-shaped electrode. The plate has low dust removal efficiency and large resistance, which cannot meet the needs of ultra-low emission of electrostatic precipitators, and needs to be improved. Contents of the invention [0003] The purpose of the present invention is to solve the defects of low dust removal efficiency and large resistance of the secondary dust re...
