Abstract
The utility model provides a diversion smoke hood used for smoke waste heat recovery. The diversion smoke hood comprises a smoke collection hood, the top end of the smoke collection hood is connected with a smoke guide pipe, a diversion hood is arranged in the smoke collection hood and positioned right below the smoke guide pipe, an air inlet is arranged at the lower end of the diversion hood, an air outlet is arranged at the upper end of the diversion hood, cross section area of the air outlet is smaller than that of the air inlet, and two sides of the lower end of the diversion hood are connected with the inner side wall of the smoke collection hood. The diversion smoke hood has the advantages that collection blind areas do not exist, so that the smoke hood is prevented from partial suction, smoke recovery rate of a cooler is increased, and development of waste heat utilizing technology in metallurgy industry is promoted; the smoke hood is low in noise in the process of using, convenient to transport and mount and the like.
Description
Technical field
The utility model relates to a kind of petticoat pipe, specifically a kind of water conservancy diversion petticoat pipe for flue gas waste heat recovery.
Background technology
In metallurgy industry, generally adopt waste heat recovery apparatus to reclaim the waste heat of hot ore deposit cooler at present, but because cooler petticoat pipe volume is larger, petticoat pipe two compare Yuan positions, lateral extent flue gas collecting pipe road junction easily form collects blind area, produce inclined to one side suction phenomenon, make a large amount of flue gases cannot enter collection conduit, cause thermal loss, steel industry Nei Ge enterprise can only reach 40%-50% to the rate of recovery of cooler flue gas is the highest at present, seriously restricts the development of metallurgy industry UTILIZATION OF VESIDUAL HEAT IN technology.
Utility model content
The purpose of this utility model is to provide a kind of water conservancy diversion petticoat pipe for flue gas waste heat recovery, and it can solve the deficiency that existing cooler petticoat pipe exists.
The utility model for achieving the above object, be achieved through the following technical solutions: comprise exhaust fume collecting hood, exhaust fume collecting hood top is connected with smoke tube, kuppe is set in exhaust fume collecting hood, kuppe is positioned under smoke tube, and kuppe lower end arranges air inlet, and kuppe upper end sets out gas port, the cross-sectional area of gas outlet is less than the cross-sectional area of air inlet, and both sides, kuppe lower end are connected with the madial wall of exhaust fume collecting hood.Kuppe upper end is connected with exhaust fume collecting hood madial wall by brace summer.Described exhaust fume collecting hood is made up of the splicing of multiple petticoat pipe assemblies, welded seal plate outside the seam of each petticoat pipe assembly.Described exhaust fume collecting hood is made up of the splicing of 5 petticoat pipe assemblies, welded seal plate outside the seam of each petticoat pipe assembly.
The utility model has the advantage of: without collecting blind area, prevent that petticoat pipe from producing inclined to one side suction phenomenon, improve cooler off-gas recovery rate, be conducive to promote the development of metallurgy industry UTILIZATION OF VESIDUAL HEAT IN technology; In petticoat pipe use procedure, noise is low, petticoat pipe transportation, easy for installation etc.

The specific embodiment
A kind of water conservancy diversion petticoat pipe for flue gas waste heat recovery described in the utility model, comprise exhaust fume collecting hood 1, exhaust fume collecting hood 1 top is connected with smoke tube 2, the interior kuppe 3 that arranges of exhaust fume collecting hood 1, kuppe 3 is positioned under smoke tube 2, and kuppe 3 lower ends arrange air inlet 4, and kuppe 3 upper ends set out gas port 5, the cross-sectional area of gas outlet 5 is less than the cross-sectional area of air inlet 4, and kuppe 3 both sides, lower end are connected with the madial wall of exhaust fume collecting hood 1.Kuppe 3 can make the air flow resistance of smoke tube 2 belows rise, and balance kuppe 3 inside negative pressure pressure everywhere, makes also can enter smoothly smoke tube 2 apart from smoke tube 2 compared with the flue gas of distant positions, prevents that petticoat pipe from producing inclined to one side suction phenomenon.
The utility model, in order to strengthen the bonding strength of kuppe 3 and exhaust fume collecting hood 1, can adopt following structure: kuppe 3 upper ends are connected with exhaust fume collecting hood 1 madial wall by brace summer 6.This structure can prevent that kuppe 3 from producing dither under the impact of air-flow, the noise that while reducing equipment operation, cooler petticoat pipe produces.
The utility model in order to transport, easy for installation, described exhaust fume collecting hood 1 can be adopted to multiple petticoat pipe assemblies splicing compositions, welded seal plate 7 outside the seam of each petticoat pipe assembly.Sealing plate 7 is for by the joint seal between each petticoat pipe assembly.In addition, sealing plate 7 material that also optional use has certain toughness and ductility is made, and offsets the thermal expansion producing after petticoat pipe assembly is heated.
According to the specification of common cooler, exhaust fume collecting hood described in the utility model 1 preferably adopts 5 petticoat pipe assemblies splicing compositions, welded seal plate 7 outside the seam of each petticoat pipe assembly.If increase the quantity of petticoat pipe assembly, the intensity of exhaust fume collecting hood 1 self can influenced, causes exhaust fume collecting hood 1 undercapacity, and the while cost of equipment can rise; If reduce the quantity of petticoat pipe assembly, in installation process, exhaust fume collecting hood 1 can produce and interfere with the component locations such as cooler chassis, and installation difficulty is larger.
