Description
Technical field
The utility model relates to a kind of steelwork converter emission-control equipment, particularly a kind of spray cooling wet-esp tower.
Background technology
Steelwork converter waste gas is mainly derived from smelting process, particularly produces a large amount of waste gas in the oxygen blast smelting phase.Dust content height in this waste gas, the concentration that contains poisonous gaseous state things such as carbon monoxide is also very high.The improvement of oxygen converter flue gas comprises thick dedusting and two stages of accurate dedusting, the thick dedusting stage mainly adopts two Wen's methods or a tower one Wen's method to remove most flue gas and coal gas, and the accurate dedusting stage generally is a wet electrical dust precipitator of arranging an electric field behind gas chamber.This method energy consumption height, maintenance of equipment amounts such as water loss is big, wastewater treatment is difficult, blower fan are big, working efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of spray cooling wet-esp tower, and the steel-making converter emission-control equipment energy consumption height, maintenance of equipment amounts such as water loss is big, wastewater treatment is difficult, blower fan that can effectively solve prior art be big, problem such as contaminate environment easily.The utility model relates to a kind of spray cooling wet-esp tower, comprise tower body, it is characterized in that: the bottom of tower body sidewall is provided with inlet mouth and leakage fluid dram, the top of tower body sidewall is provided with rupture disk, the top of tower body is provided with the air outlet and negative electrode is hung the chamber, the intravital top of tower is provided with the positive plate cathode rays parallel with some, negative electrode is hung chamber interior and is provided with negative electrode, every cathode rays is connected with negative electrode, hang between chamber and the rupture disk at negative electrode and to be provided with jet nozzle, the intravital bottom of tower is provided with several jet nozzles, and jet nozzle is fixed on the tower body sidewall, sidewall is provided with several manholes, and each jet nozzle top is provided with a manhole.Each jet nozzle is provided with two or more spray cooling shower nozzles.Described positive plate can be honeycomb fashion positive plate or planar anode plate.The number that described negative electrode is hung the chamber is two or more.The number of described rupture disk is two or more.The base plane of tower body and the angle of horizontal plane are spent more than or equal to 10, and are less than or equal to 30 degree.Advantage of the present utility model is: the utility model can effectively reduce toxic gas quantity discharged, saves energy and water, minimizing maintenance of equipment work amount and reduce cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The number that described negative electrode is hung the chamber is two or more.The number of described rupture disk is two or more.The base plane of tower body and the angle of horizontal plane are spent more than or equal to 10, and are less than or equal to 30 degree.The present invention is the integrated apparatus that spray cooling tower and wet electrical dust precipitator are united two into one.
Converter waste gas comprises flue gas and coal gas, is pressurized being drawn in the spray cooling wet-esp Tata body of blower fan, and the fog system of being made up of three, four layers of jet nozzle cools to the flue gas state of suitable wet electrical dust precipitator work.Many cathode rays are formed the cathode rays hangar system, the common electrostatic dust collection equipment of forming of cathode rays hangar system and anode, the cathode rays that is connected with high voltage electric is carried out charged processing to dust, and the dust that has electric charge overcomes pedesis trend anode under the effect of electrical forces.The granule dust that is adsorbed on the cathode and anode carries out the deashing processing by cleaning nozzle system.Water smoke in the flue gas condenses prior to dust under the driving of electric field electrostatic force and is deposited on the positive plate, is taken to the bottom of tower body by flowing water, and the base plane and the horizontal plane of tower body have certain included angle, and waste water flows to the circulatory pool of outside from leakage fluid dram.The dry converter gas of handling is discharged to the gas chamber of back from the air outlet of tower body.The exhanst gas outlet dust concentration can reach 10mg/Nm
3, can satisfy discharge index existing and environmental requirement in the future.The tower body sidewall is provided with rupture disk, for a plurality of rupture disk devices that guarantee the safety performance of the utility model in manipulating, be provided with to match; Tower body is provided with a plurality of manholes, is convenient to the long-term equipment repair and maintenance of staff.
