To achieve these goals, the technical solution used in the present invention is：Superheater safeguard structure, is arranged in flue
Superheater is connected with the drum of waste heat boiler, and the flue is vertically arranged, and the pipe level of the superheater is arranged, described mistake
The heat exchanger tube of hot device is provided with protective plate towards flue gas to side.
Flue gas superheater conveying in direction under flue, the protective plate is located at the lower section of superheater heat exchanger tube.
The protective plate is made up of the C-shaped pipes set being welded on superheater heat exchanger tube.
The lower surface of the C-shaped pipes set is evenly distributed with recess structure.
The C-shaped pipes set is flexible steel bar.
The flue includes the first flue of top and combustion chamber, the second flue that lower section connects with the first flue,
The superheater is arranged in the second flue.
The protective plate and superheater are equipped with two groups, and two groups of superheaters are each attached to the bottom of the second flue, two groups of institutes
State protective plate and be respectively the first protective plate and the second protective plate, and be made up of C-shaped pipes set,
By vibrations connector connection between the C-shaped pipes set of first protective plate and the second protective plate, described first prevents
The rapping apparatus for beaing protective plate edge is provided with by backplate and the second protective plate.
The bottom at the lower section connection position of first flue and the second flue is provided with mechanism of gathering dust.
It is an advantage of the current invention that by coordinating with flue structure, the velocity of flue gas in flue can be effectively reduced, from
And reduce it and carry amount of dust, it is to avoid adsorb excessive dust on superheater pipeline, so as to improve its service life and heat exchange effect
Really.
Description of the drawings
The mark in the content and figure of every width accompanying drawing expression in description of the invention is briefly described below：
Fig. 1 is superheater safeguard structure schematic diagram；
Fig. 2 is protection plate structure schematic diagram；
Mark in above-mentioned figure is：1st, the first flue；2nd, the second flue；3rd, superheater；4th, the first protective plate；5th, second
Protective plate；6th, heat exchanger tube；7th, C-shaped pipes set.
Arrow in Fig. 1 is combustion product gases flowing direction.
Specific embodiment
Superheater 3 is used to that the steam in drum to heat up again, and superheater 3 is arranged in flue, in order to reduce combustion
The carrying amount of dust in flue gas is burnt, flue is vertically arranged, the pipe level of superheater 3 is arranged.Safeguard structure is in the cigarette of superheater 3
Gas come to side be provided with level fixation protective plate.Protective plate can reduce flue gas flow rate speed, reduce its dust carrying amount, and
And certain dust can be adsorbed by protective plate.
In order to coordinate protective plate to improve dust-laying effect, flue includes the first flue 1 of top and combustion chamber, lower section with
First flue 1 connection the second flue 2, superheater 3 be arranged on the second flue 2 in, combustion product gases flowing direction as shown in figure 1,
The bottom that first flue 1 connects position with the lower section of the second flue 2 is provided with mechanism of gathering dust, by the first flue 1 and the second flue 2
The elbow structure of lower section, can automatically remove substantial amounts of dust, and collect removal automatically by mechanism of gathering dust.
For the protection effect for further improving protective plate, protective plate is provided with two, and respectively the first protective plate 4 and second is anti-
Backplate 5.
First protective plate 4 and the second protective plate 5 are horizontally fixed in the second flue 2, and superheater 3 is provided with two groups, is divided to two
The bottom of the second flue of layer branch 2, the first protective plate 4 is fixed on the first superheater, and the second protective plate 5 is fixed on the second superheater
On, the first superheater is located at the lower section of the second superheater.
First protective plate 4 and the second protective plate 5 are constituted by the C-shaped pipes set 7 being arranged side by side, and C-shaped pipes set 7 is fixed on side by side
In framework, there is the gap passed through for flue gas between C-shaped pipes set 7, C-shaped pipes set 7 comes to protective plate is by flue gas convex surface facing flue gas
Rapidly slow down in bottom, protective plate itself can also adsorb dust, allow it substantial amounts of can fall into dust arrester installation, reduce passing through second
Amount of dust in flue 2,
As shown in Fig. 2 the C-shaped pipes set 7 is located at the bottom of heat exchanger tube 6, i.e. flue gas comes to direction, for protecting heat exchanger tube 6,
Also the dust intercepted in flue gas can be further reduced, double protection effect is reached.
The C-shaped pipes set 7 of the first protective plate 4 and the second protective plate 5 can arrange multilayer, i.e., pacify on Multi-layer exchanging heat pipe 6
Dress C-shaped pipes set 7, it is also possible to arrange one layer, installs C-shaped pipes set 7 only on the heat exchanger tube 6 of the bottom, is slowed down according to flue gas and anti-
Shield demand is determined.
Because protective plate is made up of the C-shaped pipes set 7 being set up in parallel, the hole passed through for flue gas is provided between C-shaped pipes set 7,
Such structure contributes to slowing down flue gas, can also protect heat exchanger tube 6.Each C-shaped pipes set 7 comes uniform to direction towards flue gas
Recess structure (in numb spot distribution) is distributed with, i.e., the outer surface in C-shaped pipes set 7 is provided with recess structure, and C-shaped pipes set 7 is excellent
Choosing is made using flexible steel bar, by sunk structure, can be increased the effect of C-shaped pipes set absorption dust and be improved C-shaped pipes set drop
The effect of low flue gas flow rate, and coordinate the flexible characteristic that C-shaped pipes cover, each C-shaped pipes are enclosed within the presence of flue gas blows, C-shaped
Pipe box can occur from vibrations, and dust cake that can be automatically by absorption on C-shaped pipes set is shaken off in the dust arrester installation of lower section,
With certain self purification, the rapping for beaing protective plate edge is provided with by the first protective plate 4 and the second protective plate 5 in addition
Device, can weld vibrations transmission bar between the C-shaped pipes set 7 of the second protective plate 5, be capable of the dust put to C-shaped pipes of active
Structure is cleaned.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented and do not receive aforesaid way
Restriction, as long as employing the improvement of various unsubstantialities that method of the present invention design and technical scheme are carried out, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
