The coal-fired boiler inertia dust-removal water cooling pipe bundle arranges a water cooling pipe bundle in a coal-fired boiler body and is characterized in that the inertia dust-removal water cooling pipe bundle is arranged at the exit of a combustion chamber inside the boiler body; the upper end of the water cooling pipe bundle is connected with a boiler drum, while the lower end is connected with a collecting box; ash-blocking and dust-removal slices are arranged on the water cooling pipe bundle. The water cooling pipe bundle of the utility model has the advantages of reducing the boiler smoke emission content, eliminating the smoke, removing the dust, preventing abrasion of convection pipe bundles and extending the service life of the pipe bundles.
Description
Technical field
The utility model belongs to the boiler technology field, particularly relates to a kind of coal-burning boiler inertial dust collection water-cooled tube bank.
Background technology
At present, in field of boilers, water-cooled tube bank is made up of many rows light pipe, and it is arranged in the middle part and the afterbody of boiler as boiler heating surface, and purpose is in order to carry out exchange heat with hot flue gas, boiler heat supplying to be loaded reach specified heating parameter.But often because heating surface arranges that the unreasonable heating surface that causes is stain and stops up by fuel ash, have a strong impact on the availability and the boiler thermal output of boiler heating surface, in addition, when using solid fuel, contain a large amount of fly ash granules in the flue gas, these soot particles under the effect of high speed flue gas stream, the flush water cooler tube bundle, make the tube bank surface be subjected to sharp wear, serious meeting causes blowing out.
Summary of the invention
The utility model provides a kind of simple coal-burning boiler inertial dust collection water-cooled tube bank for solving the problem that prior art exists.
The purpose of this utility model provides a kind of heat that absorbs hot flue gas, effectively reduces the flying dust of carrying secretly in the flue gas, finishes the exchange process of heat, reduces boiler soot emission content, reaches smoke abatement and dust control and prevents the effect that convection bank is worn and torn.
Following technical scheme is adopted in the tube bank of the utility model coal-burning boiler inertial dust collection water-cooled:
The water-cooled tube bank is equipped with in the tube bank of coal-burning boiler inertial dust collection water-cooled in the coal-burning boiler body of heater, be characterized in: exit, body of heater inner combustion chamber is furnished with the tube bank of inertial dust collection water-cooled, connects drum in the water-cooled tube bank, and following Lian Jixiang is equipped with the grey dedusting sheet of resistance in the water-cooled tube bank.
The tube bank of the utility model coal-burning boiler inertial dust collection water-cooled can also be adopted following technical measures:
Described coal-burning boiler inertial dust collection water-cooled tube bank is characterized in: the preceding 1-2 comb of inertial dust collection water-cooled tube bank is a light pipe.
Described coal-burning boiler inertial dust collection water-cooled tube bank is characterized in: the back 1-2 comb of inertial dust collection water-cooled tube bank is equipped with the grey dedusting sheet of resistance.
Described coal-burning boiler inertial dust collection water-cooled tube bank, be characterized in: hindering grey dedusting sheet is dovetail shaped dedusting sheet.
Described coal-burning boiler inertial dust collection water-cooled tube bank is characterized in: dovetail shaped dedusting sheet is the steel disc that is fixedly welded on the pipe outer wall.
Described coal-burning boiler inertial dust collection water-cooled tube bank, be characterized in: the dovetail of dovetail shaped dedusting sheet points to the rightabout of flue gas stream.
Preceding two array of pipes of water-cooled tube bank are light pipe as the crust block pipe of boiler, on the outer wall of the every array of pipes of two array of pipes after the tube bank, be welded with the grey sheet of resistance, this hinders grey sheet and is dovetail shaped, dovetail points to flue gas stream rightabout, when sweep of gases is restrained, hinder grey sheet inwall at each dovetail shaped and form eddy-currents one by one, the high speed flue gas is under action of inertia, make phase mutual interference between the eddy-currents, collide, washing away the dust that hinders grey sheet and tube outer wall contamination, make the soot particle carried secretly in the flue gas collide repeatedly and the effect of gravity under sedimentation, because pipe is at the back side of the grey sheet of resistance, and hinder grey sheet coattail end towards the flue gas flow path direction, and protected the problem that tube wear brought well, realized the utility model dedusting, the purpose of abrasionproof.
Advantage that the utlity model has and good effect:
The utility model adopts the brand-new technology scheme, and a kind of coal-burning boiler inertial dust collection water-cooled tube bank is provided, and compared with prior art, its characteristics are as follows:
1. hinder the effect of grey sheet: mainly be to make flue gas generation strong disturbance, the soot particle of carrying secretly in the flue gas is settled down.
2. the effect of pipe: mainly be the exchange heat of finishing with flue gas, obtain institute's calorific requirement.
The utility model mainly is the heat that absorbs hot flue gas, reduces the flying dust of carrying secretly in the flue gas, finishes the exchange process of heat, reduces boiler soot emission content, has played smoke abatement and dust control and has prevented the effect that convection bank is worn and torn, and has prolonged the service life of tube bank.
Description of drawings
Fig. 1 is a coal-burning boiler inertial dust collection water-cooled tube bank structural representation;
Fig. 2 is that the A-A of Fig. 1 is to the sectional structure schematic diagram.
Among the figure, the 1-pipe, the 2-dovetail shaped hinders grey sheet, 3-drum, 4-collection case.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, enumerate following example now and be described in detail as follows:
With reference to accompanying drawing 1 and Fig. 2.
The water-cooled tube bank is equipped with in the tube bank of coal-burning boiler inertial dust collection water-cooled in the coal-burning boiler body of heater, its exit, body of heater inner combustion chamber is furnished with the tube bank of inertial dust collection water-cooled.The drum 3 that connects coal-burning boiler in the tube bank of inertial dust collection water-cooled, under connect the collection case 4, the light pipe 1 that preceding 2 combs of water-cooled tube bank are crust block, back 2 combs are equipped with dovetail shaped and hinder grey dedusting sheet 2, dovetail shaped dedusting sheet 2 is for being fixedly welded on the steel disc on the pipe outer wall, and the dovetail of dovetail shaped dedusting sheet 2 points to the rightabout of flue gas stream.
During present embodiment work, the high speed flue gas the utility model of flowing through, flue gas generation strong disturbance under effect of inertia, wash away towards the resistance of fume side ash plate inner surface, the soot particle of carrying secretly in the flue gas collided mutually, make soot particle collide repeatedly and the effect of gravity under settle down, be mingled with the hot flue gas of soot particle owing to be subjected to dovetail shaped to hinder stopping of grey sheet, reduced the wearing and tearing of soot particle, therefore, prolonged the service life of convection bank tube wall.
