Technical field
The utility model is to be used for the smart dust removal installation that blast furnace gas purification is used, and is applicable to that also other are inflammable, the dedusting of explosion hazard gases, as the flame cleaning of converter, town gas dedusting, continuous casting and steel rolling and dedusting etc.
Background technology
At present, the dust removal installation of blast furnace gas generally all adopts import equipment, and dust removing effects is relatively good, but import equipment costs an arm and a leg, and conditions such as maintenance of the equipment also are subjected to certain limitation.
The utility model content
The purpose of this utility model provides a kind of reasonable price, well behaved blast furnace gas purification electric precipitator.This electric precipitator satisfies users' such as heater for rolling steel, boiler needs by the udst separation to blast furnace gas to guarantee the blast furnace gas dustiness.
The electric precipitator principle of work is a dusty gas by the electric precipitator loudspeaker that enter the mouth, after the airflow-distribution board current-sharing, enter electric field equably, the nozzle that is configured in import loudspeaker and electric field top sprays in the coal gas of the electric field of flowing through after making water fogging, make and be cleaned temperature of gas, pressure, humidity and reach the purification requirement, after containing the suspension liquid particle and entering electric field, by charged and under the effect of electrical forces, captured by dust collecting electrode, and flow in the ash bucket along dust collecting electrode, enter settling tank by ash bucket then, and the coal gas after purifying is discharged from the electric precipitator outlet by electric field.
Constitutional features of the present utility model is described below:
The blast furnace gas purification electric precipitator is characterized in that: blast furnace gas purification is made up of body, water supply line, inflated with nitrogen gas exhaust duct, pulse vibrator, explosion venting device with electric precipitator; The fly-ash separator body is a body structure, be provided with dust collecting electrode and discharge electrode in body interior, be provided with the water spouting nozzle of cleaning dust collecting electrode and discharge electrode at the electric precipitator top, the fly-ash separator lower end is provided with ash bucket, be provided with nitrogen purging device on the fly-ash separator body, the nitrogen discharge device is located at dust remover roof.For making the electric precipitator safe and stable operation, on electric precipitator, be provided with a plurality of explosion venting valves.
The beneficial effects of the utility model are: rational in infrastructure, and good dedusting effect, price is low than import equipment.Charged spray Cleaning for High Capacity technology sprays into atomized water and clears up dust collecting electrode and discharge electrode, does not need the cut off high power supply during spraying, and spraying intensity and spray controlling cycle system make the electric field cleaning performance keep splendid state, reduce working cost.The high-efficiency dust collecting device adopts proprietary bimodal plate template structure, make on the dust collecting electrode surface liquid film that forms continuous flow and increase gather dust electrode surface-area and reduce air-flow velocity near the collecting plate place.The dust collecting electrode surface scribbles the electric precipitation conductive anti-corrosion coating, has higher corrosion-resistant and wear resistance.Explosion venting device control for making the electric precipitator safe and stable operation, is provided with a plurality of explosion venting valves on electric precipitator.This explosion venting valve has releasing pressure automatically, automatically replies function, is safety device in the inflammable gas dedusting.The electromagnetic hammer rapping apparatus at deposit phenomenon on collecting plate and discharge electrode of plaster, has adopted top electromagnetic hammer pulse vibrator.The size and the shaking cycle of its rapping power are adjustable.At cold district, fly-ash separator body and all pipelines are provided with lagging facility.
