Specific embodiment
As shown in Fig. 1 ~ 3, super-pressure corner tube boiler structure of boiler barrel, including shell 1, tedge 2, feed pipe 3, saturated vapor
Pipe 4, second separator 5, chemical feed pipe 6, blow-off pipe 7 and down-comer 8, the saturated steam pipe 4 and the down-comer 8 are to being set on
It states the both sides of shell 1, be connected respectively with the shell 1, the second separator 5 is set to the saturated steam pipe 4 and institute
It states shell 1 to be connected in the shell 1 at place, the feed pipe 3, the chemical feed pipe 6 and the blow-off pipe 7 pass through stent respectively
It is fixedly installed in the shell 1, the nozzle of the feed pipe 3, the chemical feed pipe 6 and the blow-off pipe 7 is opened in institute respectively
State the side-walls of shell 1.The hot water that boiler generates（Vapour）Entered inside the shell 1 by the tedge 2, hot water quality
Gently, heat is swapped during uplink, part water is converted into gaseous state, and via the second separator 5 from the saturation
Steam pipe 4 exports；Cold water inside the shell 1 is supplemented to boiler under the effect of gravity, through the down-comer 8, and water is in siphon
In the carry out self-loopa of drum and boiler room under effect.Meanwhile the feed pipe 3 is according to pressure, level condition in the shell 1
Moisturizing is carried out, the chemical feed pipe 6 and the blow-off pipe 7 are also carried out dosing in the shell 1 by system regulation or will be described outer
High concentration pot water is discharged in shell 1.
The skimming baffle structure 9 along 1 axial restraint of shell is equipped in the shell 1, the skimming baffle structure 9 will
Workspace 100 and disturbance side 200 are divided into the shell 1.The workspace 100 and the disturbance side 200 pass through described point
It is connected from 9 both ends window 10 of baffle arrangement.The saturated steam pipe 4, the second separator 5, the blow-off pipe 7 and described
Down-comer 8 is set to the workspace 100.The tedge 2, the feed pipe 3 and the chemical feed pipe 6 are set to described disturb
In dynamic side 200, steam or moisturizing by being introduced outside drum, liquid is made to be disturbed in side 200 after current stabilization, then by described described
Window 10 enters in the workspace 100, to ensure the workspace 100 liquid during Load Regulation and feedwater, dosing
Position maintains to stablize.
The skimming baffle structure 9 includes pair setting support plate 91, curved support plate 92, baffle 93 and end plate 94.It is described right
If support plate 91 and the curved support plate 92 are both secured at the inner wall of the shell 1.It is described right that the baffle 93 is fixed on
If the axis of the shell 1 is parallel between support plate 91.After being entered in the shell 1 by the steam that the tedge 2 enters,
It is hit with the baffle 93, so as to realize current stabilization in the disturbance side 200.Hot water vapor passes through dead weight after shock
Centrifugation realizes that water, gas just detach, and realizes the function of original cyclone separator and steam cleaner, described outer to simplify
Bulking block in shell 1 is conducive to increase space for maintenance, and reduce pressure drop, and then reduces boiler operatiopn cost.
The feed pipe 3 is parallel with the baffle 93, and 3 upright projection of feed pipe is on the end plate 94.By described
The moisturizing that feed pipe 3 enters is isolated in the disturbance side 200 similarly under the action of the baffle 93 and carries out current stabilization.
The end plate 94 is fixed between the end wall of the baffle 93 and the curved support plate 92 and perpendicular to the side wall of the shell 1,
The upper and lower both sides of the end plate 94 are equipped with the window 10.Water after current stabilization is located at the window of 94 lower section of end plate certainly
Mouth 10 is flowed into the workspaces 100；And the gas just detached then flows into institute from the window 10 for being located at 94 top of end plate
State in workspace 100, then by the second separator 5 after, you can led by the saturated steam pipe 4 from the shell 1
Go out.
The baffle 93 is formed by welding by several monomer splits.Hull beam is less than drum access hole bore, single to incite somebody to action
