Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of Converter Residual Heat Boiler movable gas hood of the present invention.
Fig. 2 is the enlarged diagram at the position H shown in Fig. 1.
Fig. 3 is the top view of lantern ring cavity shown in Fig. 1.
Specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of Converter Residual Heat Boiler movable gas hood, comprising: it is flat to be set to petticoat pipe
Water inlet header 2, movable gas hood ontology 3 and the water outlet header 4 of the lower section of platform 1, and be set to 1 top of petticoat pipe platform by motor 5
The reel 6 for driving rotation, is wound with elevating chain 7, the chain telescopic mouth of elevating chain 7 from petticoat pipe platform 1 is downward on reel 6
It stretches out petticoat pipe platform 1 and is connected with movable gas hood ontology 3, movable gas hood ontology 3 is exchanged heat by several horizontal positioned annulars
Pipe is longitudinally formed by stacking, and is respectively arranged with water inlet and water outlet on every annular heat exchange tube, every annular heat exchange tube into
The mouth of a river passes through the first branch pipe 8 connection water inlet header 2 respectively, and the water outlet of every annular heat exchange tube passes through the second branch pipe 9 company respectively
Pick out water header, be connected separately with a lifting pipe 10 in water inlet header 2 and water outlet header 4, every lifting pipe 10 respectively from
The pipeline extension mouth of petticoat pipe platform 1 stretches out petticoat pipe platform 1 upwards；In each pipeline extension mouth and each chain telescopic mouth respectively
It is equipped with one and is located on corresponding lifting pipe 10 and 7 outside of elevating chain and the interior lantern ring cavity 12 for setting toroidal cavity 11, own
The toroidal cavity 11 of lantern ring cavity 12 is connected to high voltage protective gas gas source 15 by the tracheae 14 with valve 13 respectively, in each lantern ring
The inner wall of cavity 12 is disposed with several circle spray heads 16 from up to down, when the high voltage protective gas warp in high voltage protective gas gas source 15
When each tracheae 14 is sprayed from the spray head 16 of each lantern ring cavity 12, high voltage protective gas can be in each lifting pipe 10 and corresponding lantern ring cavity 12
Between between gap and each elevating chain 7 and corresponding lantern ring cavity 12 gap formed sealing gland, to effectively prevent converter mouth
Flue gas is between each lifting pipe 10 and corresponding lantern ring cavity 12 between gap and each elevating chain 7 and corresponding lantern ring cavity 12
The downward loss in gap goes out to pollute environment, effectively improves site environment, improves safety in utilization；In the present embodiment, each
The inner wall of lantern ring cavity 12 is disposed with 5 circle spray heads 16 from up to down, and every circle spray head 16 is by 16 sprinkler compositions, each lantern ring
For the spout of each spray head 16 on cavity 12 towards unanimously, such sealing gland effect is good；
Working principle of the present invention is as follows:
All valves 13 are opened, the high voltage protective gas in high voltage protective gas gas source 15 can enter each lantern ring cavity 12 through each tracheae 14
Toroidal cavity 11, then sprayed through each corresponding spray head 16, thus between each lifting pipe 10 and corresponding lantern ring cavity 12 gap, with
And gap forms sealing gland between each elevating chain 7 and corresponding lantern ring cavity 12；
When blowing, make motor 5 that the rotation of reel 6 be driven to loosen elevating chain 7, the decline of movable gas hood ontology 3 is driven to cover in Converter
On mouth；When grate, so that motor 5 is driven the rotation winding elevating chain 7 of reel 6, drive movable gas hood ontology 3 to rise and open Converter
Mouthful；
