Abstract
The utility model discloses a simple structure, efficient exhaust-heat boiler of heat absorption is with movable petticoat pipe, including the collection case of intaking and the collection case of play water, be provided with the heat absorbing device between the collection case of intaking and the collection case of play water, the heat absorbing device is formed by the stack of a plurality of annular heat-absorbing pipe, and the heat absorbing device is whole to be the round platform shape, and the heat-absorbing pipe among the heat absorbing device links to each other with the collection case of play water through the branch pipe respectively with the collection case of intaking, and the upper end of heat absorbing device is provided with a plurality of jet-propelled pipes that link to each other with external air supply, and the spout of jet-propelled pipe is. The utility model has the advantages that the heat absorption area of the movable smoke hood is increased, and the sealing performance of the movable smoke hood is improved.
Description
Technical field
The utility model relates to a kind of waste heat boiler and uses movable gas hood.
Background technology
The operating condition of converter waste heat boiler is periodicity, variation sharp with the smelting process of converter.When bessemerizing, the great amount of high-temperature flue gas flows through waste heat boiler, and the thermic load of waste heat boiler sharply increases; When blowing stopped, the thermic load of waste heat boiler sharply reduced.This thermic load about 30min period of waves (being equivalent to the converter smelting cycle), abominable service condition must exert an influence to the service life of waste heat boiler.At present, the service life of converter waste heat boiler is very short, and the average life span of epimere cooling stack is about 6 years, and the life-span of hypomere cooling stack is 2～3 years, and the service condition of fire door movable gas hood is more abominable, and the life-span had only about 1 year.Accident rate is also very high in the lifetime, must often overhaul, and has both influenced output of steel, influences security of operation again.Therefore, the converter waste heat boiler particularly design of fire door movable gas hood is most important, and it directly influences the ordinary production of converter.As shown in Figure 1, movable gas hood commonly used comprises: water inlet collection case 1, be positioned at the water outlet collection case 2 of water collection case 1 top into and be connected some heat exchanger tubes 3 of water inlet collection case 1 and water outlet collection case 2, the top of water outlet collection case 2 is provided with annular water tank 4, tank 4 interior filled with water.When movable gas hood uses in reality; The top also has an epimere cooling stack 5 cylindraceous; Reduce the utilization rate of flue gas in order to prevent to spill the gap of partial fume between tank 4 and epimere cooling stack 5; In tank 4, be provided with the sealing plate 6 that the cross section is the shape of falling L, an end of sealing plate 6 is positioned at tank 4, and the outer wall of the other end and epimere cooling stack 5 offsets.Above-mentioned movable gas hood complex structure, heating surface area are little, and long-time the use in the tank 4 of back be easy to generate a large amount of lime-ash, finally influence the up-down of movable gas hood.
The utility model content
The utility model technical problem to be solved is: provide a kind of simple in structure, the waste heat boiler that heat absorption efficiency is high is used movable gas hood.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of waste heat boiler is used movable gas hood; Comprise into water collection case and water outlet collection case, be provided with heat sink between water inlet collection case and the water outlet collection case, heat sink is formed by stacking several annular endothermic tubes; And heat sink integral body is truncated cone-shaped; Endothermic tube in the heat sink links to each other with water outlet collection case with water inlet collection case through arm respectively, and the upper end of heat sink is provided with the some air jet pipes that link to each other with extraneous source of the gas, and the spout of air jet pipe is positioned at the inboard, upper end of heat sink.
Weld together through annular round steel between the said adjacent endothermic tube.
The beneficial effect of the utility model is: increased the endotherm area of movable gas hood, and improved the sealing property of movable gas hood.

Fig. 2 is the structure chart of the utility model waste heat boiler with movable gas hood;
Fig. 3 is the partial enlarged drawing between A place endothermic tube and the round steel among Fig. 2.
Among Fig. 1: 1, water inlet collection case, 2, water outlet collection case, 3, heat exchanger tube, 4, tank, 5, the epimere cooling stack, 6, sealing plate.
Among Fig. 2 to Fig. 3: 1, water inlet collection case, 2, water outlet collection case, 5, the epimere cooling stack, 7, endothermic tube, 8, arm, 9, air jet pipe, 10, round steel.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the utility model in detail.
As shown in Figure 2; A kind of waste heat boiler comprises into water collection case 1 and water outlet collection case 2 with movable gas hood, is provided with heat sink between water inlet collection case 1 and the water outlet collection case 2, and heat sink is formed by stacking several annular endothermic tubes 7; And heat sink integral body is truncated cone-shaped; Endothermic tube 7 in the heat sink links to each other with water outlet collection case 2 with water inlet collection case 1 through arm 8 respectively, and the upper end of heat sink is provided with the some air jet pipes 9 that link to each other with extraneous source of the gas, and the spout of air jet pipe 9 is positioned at the inboard, upper end of heat sink.In order to improve the sealing property of heat sink, weld together through annular round steel 10 between the adjacent endothermic tube 7---Fig. 3.
The utility model has the advantages that: above-mentioned movable gas hood is simple in structure; Endotherm area is big; After the upper end of heat sink is provided with air jet pipe 9; Utilize 9 pairs of heat sink inside of air jet pipe to pressurize, make flue gas can from the gap between heat sink and the epimere cooling stack 5, not overflow, guaranteed the utilization rate of flue gas to greatest extent.
