Technical field
The present invention relates to a kind of rotary row's steam method for dust removal and device that is used for hot disintegrating device, belong to environmental protection dust removal installation field.
Background technology
In the vexed production process of bessemer furnace slag heat in the past, can produce a large amount of steam and dust, if these steam and dust can not in time be got rid of, can accumulate in the top of workshop factory building, both influenced the sight line of overhead traveling crane operation, bring potential safety hazard, also can increase the weight of the corrosion of equipment in factory building self steel construction and the factory building.The dust removal installation of bleeding in the past can not well address these problems, and can not satisfy modern production to requirement on environmental protection.
Summary of the invention
The purpose of this invention is to provide a kind of rotary row's steam dust removing device that is used for hot disintegrating device, comprise swivel arrangement, smoke gas collecting apparatus, spray equipment and gas exhaust duct.Swivel arrangement is positioned at the side of hot disintegrating device near gas exhaust duct; Smoke gas collecting apparatus is positioned at spray equipment top, and the two connects by the welding between the steel plate; Spray equipment is tiled on the hot disintegrating device, and being welded to connect by H shaped steel between the swivel arrangement; Gas exhaust duct connects smoke gas collecting apparatus and total pipeline; Spray equipment connects feedwater piping outward.
Described swivel arrangement comprises drive unit, changed course pulley gear and bracing or strutting arrangement.Drive unit involves by wireline with the changed course pulley gear, and bracing or strutting arrangement is as the support platform of changed course pulley gear.
Described smoke gas collecting apparatus comprises gas skirt and output channel, and the two is steel structural form, and gas skirt and output channel are welded to connect, and output channel uses flange to be connected with gas exhaust duct.
Described spray equipment comprises water pipe and atomizing nozzle.Atomizing nozzle is in the arranged beneath of gas skirt, 4 atomizing nozzles of each gas skirt arranged beneath.
Described gas exhaust duct comprises metallic hose and main exhaust pipeline.Be connected by flange between metallic hose and the main exhaust pipeline.
Described a kind of rotary row's steam method for dust removal that is used for hot disintegrating device comprises the steps, rotary row's steam dust removing device is mounted to the appointment station, and spray equipment is covered on original hot disintegrating device; Connect gas exhaust duct and total pipeline and spray equipment and feedwater piping respectively; Starting spray equipment fetches water to high temperature bessemer furnace slag in the vexed pond of heat; Fetch water after the end, rotary row's steam dust removing device is opened, conveniently slag tap by swivel arrangement; Slag tap after the end, rotary row's steam dust removing device is covered wait use next time on the hot disintegrating device.The swivel arrangement of rotary row's steam dust removing device is installed in original hot disintegrating device one side, and rotary row's steam dust removing device relies on self gravitation to be buckled on the water sealed tank of hot disintegrating device.The angle of rotary row's steam dust removing device being opened by swivel arrangement is controlled between 80~89 degree, and optimal angle is 87.3 degree.
In sum, compact construction of the present invention integrates spray and the dedusting of row's steam, and execute-in-place is simple and reliable, and row's steam dedusting explosion-proof effect is good.

Embodiment
Be the structural representation of the rotary row's steam dust removing device of the present invention as Fig. 1,2, comprise swivel arrangement 1, smoke gas collecting apparatus 2, spray equipment 3 and gas exhaust duct 4.
Described swivel arrangement 1 comprises drive unit 1-1, changed course pulley gear 1-2, bracing or strutting arrangement 1-3.Drive unit 1-1 and changed course pulley gear 1-2 involve by wireline, and bracing or strutting arrangement 1-3 is as the support platform of changed course pulley gear 1-2.Drive unit 1-1 is as power resources, and the break-in effect by changed course pulley gear 1-2 is passed to whole rotary row's steam dust removing device with power, and then finishes rotatablely moving of whole device.
Described smoke gas collecting apparatus 2 comprises gas skirt 2-1 and transport pipe 2-2.The two is steel structural form, is welded by some steel plates, angle steel and Welded Steel Pipe, is used for supporting smoke gas collecting apparatus 2.Carry the masterpiece of coming to be used for smoke gas collecting apparatus 2 by swivel arrangement 1, thereby drive rotatablely moving of smoke gas collecting apparatus 2.
Described spray equipment 3 comprises water pipe 3-1 and atomizing nozzle 3-2.Atomizing nozzle is in the arranged beneath of gas skirt, 4 atomizing nozzles of each gas skirt arranged beneath.Water pipe 3-1 is connected on the feedwater piping 6 by flange.
Described gas exhaust duct 4 comprises metallic hose 4-1 and main exhaust pipeline 4-2, is connected by flange between metallic hose 4-1 and the main exhaust pipeline 4-2.The other end of metallic hose 4-1 is connected on the main pipe line 5 by flange.
With reference to Fig. 1, its row's steam method for dust removal comprises the steps: to start the drive unit 1-1 of swivel arrangement 1, and swivel arrangement 1 driven rotary formula row steam dust removal installation is buckled in the hot disintegrating device top that the high temperature bessemer furnace slag is housed; Gas exhaust duct 4 is connected with total pipeline 5; Water pipe 3-1 is connected with feedwater piping 6; The high temperature bessemer furnace slag that starts 3 pairs of hot disintegrating device inside of spray equipment is fetched water, and steam that produces in this process and flue dust enter total pipeline 5 through smoke gas collecting apparatus 2 and gas exhaust duct 4; After treating that flue gas is collected the discharging end, start the drive unit 1-1 of swivel arrangement 1, the angle that rotary row's steam dust removing device is opened is controlled between 80~89 degree, and optimal angle is 87.3 degree, makes things convenient for hot disintegrating device to slag tap; Wait to slag tap after the end, from the drive unit 1-1 of new startup swivel arrangement 1, swivel arrangement 1 driven rotary formula row steam dust removal installation is buckled in the hot disintegrating device top of slagging tap and finishing, and waits for next the use.
Embodiment: the present invention has well solved a large amount of steam that produce in the vexed process of fetching water of converter slag heat and the emission problem of dust.For the vexed technology of converter slag heat is a kind of effective means.In treating processes in the past, when cool water shower is surperficial to the converter slag of molten state, can produce a large amount of water vapour and dust; And these water vapour and dust often are to be suspended in the air.The employee often is in work under a kind of like this rugged environment in the workshop, and its health problem is caused very big hidden danger; Simultaneously, a large amount of water vapour produce steel-structure factory building and corrode, and dust is deposited in the factory building top and has the danger of pressing the factory building that collapses; The present invention has solved the safety dumping problem of steam in this process and dust well.
