Description
Technical field
Soot blower for boiler hearth technical field is the utility model is related to, is a kind of hearth soot blower.
Background technology
At present, Opposite Firing Boiler because front-back wall water-cooling wall be mounted with secondary air box lead to not arrange burner hearth blow
Grey device, so as to cause near nozzles and front-back wall coking can not clear up, coking can cause furnace outlet gas temperature rise to cause
Overheating steam temperature is higher, overtemperature of tube wall；Water-cooling wall caloric receptivity in coking position is reduced simultaneously, causes circulation water velocity to decline, meeting when serious
Make circulatory stasis and cause Waterwall tube failure;Increase heat loss due to exhaust gas simultaneously, reduce boiler efficiency, needed when coking is serious at blowing out
Reason.
The content of the invention
The utility model provides a kind of hearth soot blower, overcomes the deficiency of above-mentioned prior art, and it can effectively be solved
Soot blower for boiler hearth certainly can not be installed because secondary air box is disposed with the front-back wall of Opposite Firing Boiler, cause fire
The problem of mouth and front-back wall coking can not clear up.
The technical solution of the utility model is realized by following measures：A kind of hearth soot blower, including it is front and rear
Wall face-fired boiler, secondary air box and soot blower for boiler hearth, Opposite Firing Boiler front wall outside from the inside to the outside
Secondary air box and soot blower for boiler hearth are respectively equipped with, is respectively equipped with from the inside to the outside in the outside of the rear wall of Opposite Firing Boiler
Secondary air box and soot blower for boiler hearth, perforate, soot blower for boiler hearth bag are respectively equipped with the water-cooling wall of front wall and the water-cooling wall of rear wall
Soot blower body, ash gun and nozzle are included, ash gun is installed in the inner of soot blower body, in the fixed peace in the inner of ash gun
Equipped with nozzle, sleeve pipe is mounted in each secondary air box, ash gun is located in sleeve pipe, and nozzle passes through sleeve pipe and perforate and position
In in water-cooling wall.
Here is the further optimization and/or improvements to above-mentioned technical proposal：
Above-mentioned sleeve pipe is using left wide right narrow trapezoidal sleeve pipe.
Above-mentioned also to include pilot sleeve, pilot sleeve is located on the outside of Opposite Firing Boiler and is sleeved on secondary air box
On the ash gun of inner side.
Above-mentioned pilot sleeve is fixedly mounted on the outside of Opposite Firing Boiler.
Above-mentioned pilot sleeve is by suspention on the outside of Opposite Firing Boiler.
Above-mentioned soot blower body upper end is installed with hanging apparatus.
The utility model reasonable and compact in structure, it is easy to use, by setting sleeve pipe in secondary air box, nozzle is passed through
Sleeve pipe and perforate are simultaneously in the water-cooling wall, so as to reach near cleaning nozzles and the purpose of front-back wall coking.
Brief description of the drawings
Accompanying drawing 1 is the main view broken section structural representation of the best embodiment of the utility model.
Coding in accompanying drawing is respectively：1 is Opposite Firing Boiler, and 2 be secondary air box, and 3 be water-cooling wall, and 4 be to blow
Grey device body, 5 be ash gun, and 6 be nozzle, and 7 be trapezoidal sleeve pipe, and 8 be pilot sleeve, and 9 be hanging apparatus, and 10 be front wall, and 11 are
Wall afterwards.
Embodiment
The utility model is not limited by following embodiments, can according to the technical solution of the utility model and actual conditions come
Determine specific embodiment.
In the utility model, for the ease of description, the description of the relative position relation of each part is according to specification
The Butut mode of accompanying drawing 1 is described, such as：The position relationship of upper and lower, left and right etc. is the Butut according to Figure of description
Direction determines.
The utility model is further described with reference to embodiment and accompanying drawing：
As shown in Figure 1, the hearth soot blower includes Opposite Firing Boiler 1, secondary air box 2 and burner hearth soot blowing
Device, secondary air box 2 and soot blower for boiler hearth are respectively equipped with from the inside to the outside in the outside of the front wall 10 of Opposite Firing Boiler 1,
Secondary air box 2 and soot blower for boiler hearth are respectively equipped with from the inside to the outside in the outside of the rear wall 11 of Opposite Firing Boiler 1, preceding
Perforate is respectively equipped with the water-cooling wall 3 of wall 10 and the water-cooling wall 3 of rear wall 11, soot blower for boiler hearth includes soot blower body 4, ash gun
5 and nozzle 6, ash gun 5 is installed in the inner of soot blower body 4, nozzle 6 is installed with the inner of ash gun 5, every
Sleeve pipe is mounted in individual secondary air box 2, ash gun 5 is located in sleeve pipe, and nozzle 6 is through sleeve pipe and perforate and is located at water-cooling wall 3
It is interior.So, by setting sleeve pipe in secondary air box 2, nozzle 6 is through sleeve pipe and perforate and in water-cooling wall 3, so as to reach
Clear up nozzles nearby and front-back wall coking purpose.Opposite Firing Boiler 1 and soot blower for boiler hearth are prior art, are blown
