Description

Flue gas dust removal device for ladle hot repair

Technical Field

The utility model belongs to the technical field of steelmaking ladle inspection and clearance restoration operation, concretely relates to ladle hot repair flue gas dust collector.

Background

The traditional steel-making ladle hot repair operation is flue gas dust removal equipment arranged at a fixed position in a steel-making factory building, and flue gas and dust generated by the ladle hot repair operation cannot be timely extracted into a flue gas dust removal pipeline for removing dust in consideration of the limitations of molten steel lifting and sites. A large amount of high-temperature heavy metal dust generated by ladle hot repair is dissipated into the air, so that the problem that operators who work on site wear the mask cannot fundamentally solve the problem of inhaling fine heavy metal dust, and the dust absorbed under the condition of large amount of dust after long-term work is accumulated in the lung of a human body can cause pneumoconiosis and can also cause diseases such as rhinitis, pharyngitis, bronchitis and the like. In addition, the skin mucosa can be damaged, and the patient can have rash and dermatitis.

And under the high-temperature condition of the hot repair operation of the steel-making ladle, diseases directly caused by high temperature comprise sunstroke and psychogenic neurological disorder. In a high-temperature environment, because a human body is in a heat stress state, sympathetic nerves are excited, a large amount of sweat is produced, the blood viscosity is increased, a cardiovascular system is in a high-load running state, and the function of a digestive system is weakened, so that the original disease aggravation is caused, for example, the blood pressure is violently changed in the early and late heating stages, heart diseases can be induced, high blood and coronary heart diseases appear, and the like. High temperature as a meteorological factor can directly act on human body, resulting in heatstroke.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a to solve a large amount of high temperature flue gases that have the dust that the ladle hot repair in-process produced, ladle hot repair place environment is abominable, receives the great problem of the degree of difficulty with the influence of handling of environment and equipment to the collection of smoke and dust.

In order to achieve the above object, the utility model discloses a technical scheme be:

the utility model provides a ladle hot repair flue gas dust collector, repair the car including the heat, including the clean room, the clean room includes that roof and symmetry set up in the side of roof both sides and keep off the cigarette wall, keep off the cigarette wall and keep off the cigarette wall after with before the roof both ends set up respectively, the top that keeps off the cigarette wall and keep off the cigarette wall after with before, the bottom is the free end, set up dustproof curtain on the free end, still wear to be equipped with the dust removal pipeline on the roof, dust removal pipeline and electrostatic precipitator intercommunication, the one end of clean room sets up operation platform, the last fender fire dolly that sets up of operation platform, the one side that keeps off the fire dolly is close to the clean room sets up the fender fire board, the top of fender fire board is close to but contactless with the free end of preceding fender cigarette wall, set up the hot car in the clean room, the one end that the operation platform was kept away from to the hot car sets up on-board, the top of on-board is close to but contactless with the free end of back fender cigarette wall.

In order to further realize the utility model discloses, the dust removal pipeline includes two at least, evenly sets up on the axis of roof, and the air inlet of dust removal pipeline sets up conical dust removal screen panel. The conical dust removal net cover can form a circular negative pressure area at the air inlet, so that high-temperature smoke dust at the top of the dust removal chamber in a larger range around the dust removal net cover can be conveniently sucked, and a larger suction pressure is formed; when the steel ladle is accidentally splashed, the mesh enclosure can also effectively prevent the splashed granular steel slag or flaky steel slag from entering the dedusting pipeline, so that the pipeline is prevented from being blocked.

In order to further realize the utility model discloses, the bottom of dust curtain is less than the top surface of fire damper and on-vehicle fire damper.

In order to further realize the utility model discloses, operation platform is last to set up the track, and the track sets up with hot repair car moving direction is perpendicular, and the removal wheel card of keeping off the fire dolly is located in the track.

In order to further realize the utility model discloses, the width of keeping off the fire board is not less than the side of clean room and keeps off the distance between the smoke wall, and the width of on-vehicle keeping off the fire board is not more than the distance between the side fender smoke wall.

In order to further realize the utility model discloses, keep off fire plate, on-vehicle fire plate, preceding keep off the cigarette wall and keep off the cigarette wall after and be parallel to each other, all keep off the cigarette wall with the side perpendicular.

The utility model discloses compare in prior art's beneficial effect do:

the utility model discloses a set up a large amount of high temperature flue gas and the dust that the fire board of two activities produced the ladle hot repair operation in-process and carry out effectual blockking, and aspirate the clean room through dust removal pipeline and electrostatic precipitator, make its inside suitable negative pressure that produces, take away the high temperature smoke and dust that the hot repair operation produced, flow through the air and reach the quick collection processing to the high temperature smoke and dust, the smoke and dust particulate matter and the site temperature that keep the operation place environment are in the standard range, the change of equipment layout mode, scientific lifting means safety, environmental protection dust removal effect is improved.

The utility model discloses a preceding keep off the cigarette wall and keep off the cigarette wall after and can effectively reduce the clearance between fender fire board and the clean room roof, the rethread dustproof curtain from top to bottom covers in the front keep off the cigarette wall and keep off the seam crossing of cigarette wall and fender fire board and on-vehicle fender fire board with the back, further reduce the clearance, improve the clean room seal, reduce the pollution of dust to the external world, promote the flue gas and collect the ability, the lower extreme of dustproof curtain is laminated respectively in the outside of keeping off fire board and on-vehicle fender fire board under the negative pressure effect, further reduce the gap.

Because the negative pressure is produced by the clean room top, consequently the air flow direction in the clean room is circulating from bottom to top, consequently the utility model discloses well fender fire dolly and hot repair vehicle bottom wheel department can get into fresh air, not through the temperature that can suitably reduce in the clean room, can also suitably reduce the temperature of device and ladle in the whole environment.

The utility model discloses can reach the effectual purpose of removing dust in shorter time, reduce poisonous harmful high temperature flue gas and the dust that produces in the site environment, improve operating personnel's operation environment, reduce the worker and receive occupational degree of harm, improve the rational utilization of dust collecting equipment in finite space.
