Gas-assisted double-fluid electrostatic atomization device in desulfurization tower

Abstract

The invention discloses a gas-assisted two-fluid electrostatic atomization device in a desulfurization tower. The device comprises an atomization generation chamber, the atomization generation chambercomprises an insulating air duct, the upper end of the insulating air duct is connected with an outlet of a flow dividing and stabilizing pipeline, a one-way conduction plate is hinged to the bottomof a cylindrical section, the spray inlet pipeline and the nozzle are arranged in the insulating air duct along the central axis, flow deflectors are sleeved outside the outlet section of the spray inlet pipeline and are divided into an inner flow deflector and an outer flow deflector, the inner flow deflector and the outer flow deflector extend downwards from the outlet of the flow dividing and stabilizing pipeline, the inner walls and the outer walls of the inner flow deflector and the outer flow deflector are hydrophobic coatings, a grounded first copper ring is arranged on the edge of theinner wall of the bottom of the inner flow deflector, a second copper ring connected with a high-voltage electrostatic generator is arranged on the edge of the bottom inner wall of the outer flow deflector, a grounding copper ring is used as an adjusting electrode, the problem that the surface of the electrode is prone to entrainment of water mist in the charged spraying process of the induction charged nozzle is effectively solved, and meanwhile high-humidity gas can be prevented from flowing back into the nozzle to wet the electrode.

Description

technical field [0001] The invention belongs to the field of flue gas purification, and in particular relates to a gas-assisted two-fluid electrostatic atomization device applied in a desulfurization tower. Background technique [0002] With the rapid development of my country's industry, the problem of environmental pollution has become increasingly prominent. Faced with the increasingly stringent factory exhaust gas emission standards issued by the state, most of the existing coal-fired thermal power plants, coking plants, and building materials factories have implemented desulfurization and dust removal technology when discharging flue gas. [0003] Most of the current desulfurization towers use spray towers. Due to the large size of spray droplets and other factors, there are often problems such as insufficient contact with fog liquid and easy escape of flue gas, resulting in low desulfurization and dust removal efficiency. If traditional spraying technology is used, Du...

Problems solved by technology

[0004] In order to solve the deficiencies in the prior art, the present invention proposes a gas-assisted two-fluid electrostatic atomization device applied in the desulfurization tower. The present invention adopts the air curtain type gas-assisted design and installs a grounding As a way to adjust the electrode, the copper ring effectively solves the problem that the surface of the electrode is easy to absorb water mist during the charging spraying process of the induction charging nozzle. Breakdown makes the system unable to operate stably, which ensures the efficient removal of sulfur-containing flue gas in the desulfurization tower by charged water mist
