Abstract
The utility model discloses a folding-type flue, which comprises a suction fan, an inlet connecting box, a perpendicular flue, a suction fan outlet flue, an absorption tower, a chimney, an absorption tower outlet flue and a bracket. The suction fan is longitudinally arranged; the absorption tower is placed at one side of the suction fan; the inlet connecting box is longitudinally arranged above the suction fan; the inlet connecting box is communicated with the suction fan through the perpendicular flue; the suction fan outlet flue is communicated with the absorption tower; the absorption tower outlet flue is placed above the inlet connecting box and is communicated with the chimney; and the inlet connecting box and the absorption tower outlet flue are respectively fixed on the bracket. The folding type flue has the advantages that: the problems that the floor area is large, the initial cost is high and the like in a conventional arrangement scheme are solved, the land allocation of the overall main machine hall region is reduced, the flue is arranged in a high-low space and shares a set of brackets to support so that the floor area is small, a pipeline connected between the brackets is short, the work amount of the bracket is little, therefore, the construction period is shorter and the initial cost is lower.
Description
Technical field:
The utility model relates to a kind of flue, relates in particular to a kind of folded formula flue.
Background technology:
Lateral arrangement: the arrangement of a kind of equipment in the thermal power plant, vertical with the main building longitudinal axis with the equipment center line usually is lateral arrangement.
Vertically arrange: the arrangement of a kind of equipment in the thermal power plant, parallel with the main building longitudinal axis with the equipment center line usually serves as vertically to arrange.
Can main building be the main heavy construction in thermal power plant, and whether main building is arranged reasonable, not only is directly connected to the height of engineering construction cost, safety after also can building up power plant, economical operation affects.For making power plant in intense market competition, stand on the invincible position, in project engineering stage, the main building arrangement to be optimized fully, the reasonable consideration device layout is very necessary to reducing the engineering construction cost.
In the flue arrangement of routine, the induced-draught fan lateral arrangement is between deduster and chimney.When adopting single-row induced-draught fan, the deduster exhaust pass enters induced-draught fan after converging by header, and the flue of induced-draught fan outlet directly enters the absorption tower.The absorption tower exhaust pass directly enters the main chimney flue (when the bypass flue is arranged) of chimney or chimney both sides.
When adopting the biserial induced-draught fan, after converging by header, the deduster exhaust pass enters two induced-draught fans more respectively, after merging into a flue, the flue of two induced-draught fan outlets inserts the absorption tower again.The absorption tower exhaust pass directly enters the main chimney flue (when the bypass flue is arranged) of chimney or chimney both sides.
Above-mentioned arrangement is bigger from the distance that deduster is exported between the chimney, and the floor space that flue is arranged is bigger, and it is more to make the used steel material of flue, and the insulation material consumption is more, and construction period is corresponding longer.The induced-draught fan inlet flue duct is arranged in the top of air draught unit room, can not adopt public flue stent support with induced-draught fan exhaust pass and absorption tower exhaust pass, and the construction volume of flue support is bigger, and the material usage of flue support is more, and initial cost is higher relatively.
The utility model content:
First purpose of the present utility model is to provide a kind of saving floor space, saves the folded formula flue of investment.
Second purpose of the present utility model is to provide a kind of optimization pipe arrangement, saves the folded formula flue of floor space.
First purpose of the present utility model is implemented by the following technical programs: a kind of folded formula flue, include induced-draught fan, inlet connects case, vertical gas pass, the induced-draught fan exhaust pass, the absorption tower, chimney, absorption tower exhaust pass and support, described induced-draught fan is vertically arranged, described absorption tower places described induced-draught fan one side, described inlet connect case vertically be arranged in described induced-draught fan directly over, described inlet connects case and is communicated with described induced-draught fan by described vertical gas pass, described induced-draught fan exhaust pass is communicated with described absorption tower, described absorption tower exhaust pass place described inlet connect case directly over and be communicated with described chimney, described inlet connects case and described absorption tower exhaust pass is separately fixed on the described support.
Second purpose of the present utility model implemented by the following technical programs: a kind of folded formula flue, include two induced-draught fans, inlet connects case, vertical gas pass, the induced-draught fan exhaust pass, the absorption tower, chimney, absorption tower exhaust pass and support, two described induced-draught fans are vertically arranged, described absorption tower places described induced-draught fan one side, described inlet connect case vertically be arranged in described induced-draught fan directly over, described inlet connects case and is communicated with described induced-draught fan by described vertical gas pass, two described induced-draught fan exhaust pass merge the back and are communicated with described absorption tower, described absorption tower exhaust pass place described inlet connect case directly over and be communicated with described chimney, described inlet connects case and described absorption tower exhaust pass is separately fixed on the described support.
Advantage: the utility model has solved in the conventional arrangement problems such as floor space is big, initial cost height, has reduced the occupation of land index in whole main building zone, particularly for the nervous relatively case of place situation, has more outstanding advantage.Optimize pipe arrangement, flue adopts the height bit space to arrange that a public pack support supports as far as possible, and floor space is little, and the pipeline that connects between mutually is short, and the support quantities is few, so construction period is shorter, initial cost is lower.In addition, support is more concentrated, can be easy to form framework between each structure, more helps the stability of total.
