Abstract
The utility model discloses a convenient-to-transport water cooling type high-temperature furnace smoke pipeline, which is formed by continuously welding small-diameter steel pipes through rib fins, wherein the cross section formed by continuously welding the small-diameter steel pipes through the rib fins is in a rhombus shape or a square shape or a polygon shape with more than four edges. The convenient-to-transport water cooling type high-temperature furnace smoke pipeline has the advantage that the transportation is convenient.
Description
Technical field
The utility model belongs to boiler cigarette air channel technical field, is specifically related to a kind of stove smoke pipe road that is applied in the boiler using brown coal.
Background technology
In the blower mill unit pulverized-coal system in boiler using brown coal power plant, smoke mouth to the high temperature boiler flue gas tube road that blower mill enters the mouth from boiler using brown coal, its pumped (conveying) medium temperature is up to 1100 ℃, and the design in high temperature boiler flue gas tube road at present, manufacturing have two kinds of forms.
First kind is interior insulation form, and promptly the high temperature boiler flue gas tube road adopts ordinary carbon steel sheet material to be welded, and the inner refractory brick that adopts is built by laying bricks or stones or inner lining as thermal insulation material and wearing-proof refractory material.In the starting and stopping process of boiler and coal pulverizer, high temperature furnace cigarette temperature sharply changes between 20-1100 ℃.Because the insulation construction form thermal compensation ability of pipeline itself is relatively poor, refractory brick or insulation material and wearing-proof refractory material will become flexible after operation a period of time, produce obscission, and then the carbon steel tube wall is directly contacted with high-temperature flue gas, cause pipeline owing to hold and can't stand high temperature and burnt out, seriously leak out, cause drying capacity of pulverizer deficiency, radiation loss to increase, reduce the economy of operation.In addition because the insulation and fixedly bitch fall into coal pulverizer, also cause coal pulverizer impeller and beater plate impaired, thereby cause blowing out, shutdown, increased maintenance load, maintenance cost and degree of danger.
Second kind is outer insulation form, and promptly the high temperature boiler flue gas tube road adopts high-temperature alloy steel pipe, outsourcing heat-resistant insulation material.In the starting and stopping process of boiler and coal pulverizer, conduit upper mixing chamber position is owing to be subjected to the influence of temperature acute variation, and the tube wall crack performance often appears in the reason of aspect such as processing and manufacturing in addition.In actual moving process, the pipeline that has occurs than long crack, and suspension and support pipe portion snaps, and local fracture appears in pipeline when serious, even the pipeline sinking, causes blowing out, shutdown.
Two kinds of forms to sum up, at present high temperature boiler flue gas tube road difficult design, investment is big, service condition is abominable, maintenance workload is big.
Afterwards, a kind of water-cooled high temperature boiler flue gas tube road occurred, pipeline is a circular cross-section, and pipeline employing carbon steel path seamless steel pipe around forming, passes through the fin continuous welding along circumferential ring between the carbon steel path seamless steel pipe.This water-cooled high temperature boiler flue gas tube road unit length heat transfer area is big, long service life, can regulate flue-gas temperature, bearing capacity height, stable, can reduce heat loss again simultaneously, increase economic efficiency.
But this water-cooled high temperature boiler flue gas tube road is owing to be designed to circle, and the bore of pipeline is bigger usually.Therefore pipeline occupation space after making is also bigger, and this just causes the inconvenience of transportation, and a car only can transport the pipeline of minute quantity.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of water-cooled high temperature boiler flue gas tube road of convenient transportation, to overcome the defective that prior art exists.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of water-cooled high temperature boiler flue gas tube road of convenient transportation, it adopts the path steel pipe to form by the fin continuous welding, it is characterized in that: the cross section that described path steel pipe is connected into by the fin sequential welding is prismatic or square or the polygon more than four limits.
The above polygon in described four limits is regular hexagon or regular pentagon.
Adopt technique scheme, the path steel pipe is welded into square or the polygon more than four limits.When pipeline is made, only need the path steel pipe is welded into required pipeline on one side like this, then monolateral the stacking up of these pipelines transported, wait to arrive the boiler job site again with the monolateral pipeline that is welded into of these pipelines.Because pipeline is monolateral only to be in line path steel pipe, it is little therefore to take up room, and it is monolateral to transport a large amount of pipelines at every turn, therefore is beneficial to transportation more, thereby reduces cost.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is a foursquare water-cooled high temperature boiler flue gas tube of the present utility model road section of structure;
Fig. 2 is an orthohexagonal water-cooled high temperature boiler flue gas tube of the present utility model road section of structure;
Fig. 3 is the monolateral stacked system schematic diagram of pipeline.
Among the figure:
The 100-pipeline, the 200-steel pipe, the 300-fin, the 400-pipeline is monolateral.
The specific embodiment
As shown in Figure 1, the water-cooled high temperature boiler flue gas tube road of convenient transportation of the present utility model, its cross section is positive square, pipeline 100 is by adopting carbon steel path seamless steel pipe 200 to form by fin 300 continuous weldings.
Because pipeline section adopts square, so during fabrication only welded pipe line on one side, then can the pipeline monolateral 400 that welding is good stack up (as shown in Figure 3) is transported to the boiler job site and carries out the assembly unit welding, forms complete pipeline.Since pipeline is monolateral take up room little, can ranked and stacked pile, thus it is monolateral once to transport many pipelines.Therefore, the utlity model has the advantage of convenient transportation.
Certainly, in actual implementation process, the cross section of pipeline can not only be confined to square, can also be prismatic, can also be designed to regular pentagon or regular hexagon (as shown in Figure 2) as required, can realize the purpose of the convenient transportation of the utility model equally.
But; those skilled in the art will recognize that; the above-mentioned specific embodiment is exemplary; be in order better to make those skilled in the art can understand this patent; can not be interpreted as it is restriction to this patent protection domain; so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope of this patent protection.
Claims (2)
1. one kind makes things convenient for the water-cooled high temperature boiler flue gas tube road that transports, and it adopts the path steel pipe to form by the fin continuous welding, it is characterized in that: the cross section that described path steel pipe is connected into by the fin sequential welding is prismatic or square or the polygon more than four limits.
2. the water-cooled high temperature boiler flue gas tube road of convenient transportation according to claim 1 is characterized in that: the above polygon in described four limits is regular hexagon or regular pentagon.
