Abstract
The utility model belongs to the technical field of heating equipment, and particularly relates to a drawer-type built-in economizer structure applied to a fuel (gas) boiler. The economizer structure comprises a flue. A supporting beam is arranged in the flue. An economizer is installed in the flue and placed on the supporting beam. The outer side of the flue is provided with a square installation hole matched with the shape of the economizer. A flue flange is welded to the edge of the installation hole. A sealing pad is arranged between the flue flange and the economizer. The economizer is formed by an economizer tube bundle, a framework and a panel in an integrated mode. The economizer tube bundle is welded in the framework, the outer end of the framework is welded to the panel, the sealing pad is arranged between the panel and the flue flange, and the panel is connected with the flue flange through bolts. The economizer structure can achieve the purposes of easy installation, convenient maintenance, the compact structure and close welding line, and improves heating efficiency of the whole boiler.
Description
Technical field
The utility model belongs to the heating equipment technical field, is specifically related to a kind of built-in economizer structure of drawer type that is applied on fuel oil (gas) boiler.
Background technology
In order to recycle the waste heat in the boiler exhaust gas, improve boiler overall thermal efficient, often need export the position at boiler tail flue gas and set up an economizer.On fuel oil (gas) boiler, in order to reach the effect of economizer and boiler body integrated design, compact conformation, saving floor space, often need the built-in economizer of configuration.
The utility model content
In order to reach simple, maintenance convenience, compact conformation, purpose that seam is tight are installed, the utility model provides a kind of drawer type built-in economizer.
The built-in economizer structure of a kind of drawer type, comprise flue, brace summer is installed in the described flue, economizer is installed in the described flue, described economizer is placed on the brace summer, an installing hole that is complementary with the economizer profile is offered in the described flue outside, and the edge of described installing hole is welded with flue flange, between described flue flange and the economizer sealing gasket is set.
Preferably, described economizer is dressed up one by economizer tube bank, framework, panel sets, gets one's things ready and be welded in the framework in described economizer tube, and the outer end dress of described framework is welded in panel, between described panel and the described flue flange sealing gasket is set, bolt is connected between described panel and the described flue flange.
Preferably, described flue is offered square installing hole.
The utility model has taked above-mentioned corrective measure to carry out, and its beneficial effect is:
1, waste heat distributes and lacks, and compares with the other types economizer, is reaching under the situation of same thermal power, and economizer volume and steel consumption amount only are the 30-50 % of other economizers; Saved the floor space that economizer is installed simultaneously.
2, install simply, economizer carries out integrated design, manufacturing as the part of boiler, and does not need to install separately in addition.Because whole consideration boiler flue inner space layout is carried out global design after the factors such as flue gas resistance, heat exchange area, both can improve boiler overall thermal efficient simultaneously, can guarantee boiler safe operation under good, stable operating mode again.
3, maintenance is convenient, and the economizer tube bank can disassemble whole economizer when needing maintenance from flue, economizer is installed on the flue after the maintenance again.
4, seam is tight, as long as served as a contrast encapsulant between panel and flue flange, tightens sieve bolt when economizer is installed, and can guarantee sealing property, anti-leak-stopping cigarette; And can dismantle repeatedly.
Description of drawings
Fig. 1 is the decomposing schematic representation of the utility model embodiment 1;
1 is flue among the figure, the 2nd, and flue flange, the 3rd, brace summer, the 4th, framework, the 5th, panel, the 6th, economizer tube bank.
The specific embodiment
The contrast accompanying drawing is further described the utility model in conjunction with the embodiments below:
With reference to the built-in economizer structure of a kind of drawer type shown in Figure 1, formed by flue 1, flue flange 2, brace summer 3, framework 4, panel 5, economizer tube bank 6, wherein economizer is formed one by framework 4, panel 5, economizer tube bank 6.Flue 1 is installed in boiler tail, and brace summer 3 dresses are welded in flue 1 inboard, have a square installing hole that matches with the economizer profile in the outside of flue 1, and the edge of square installing hole is welded with flue flange 2.Economizer tube bank 6 dresses are welded in the framework 4, and the outer end of framework 4 dress is welded on the panel 5, and panel 5 is connected with flue flange 2 usefulness bolts, and sealing gasket is set between the two.
During assembling, economizer inserts from flue 1 outboard square-like installing hole, whole economizer just is placed on the brace summer 3 of flue 1 inwall, filling up sealing gasket between panel 5 and the flue flange 2 then, tighten the bolt between flue flange 2 and the panel 5, economizer just is installed on the flue 1 easily, dismantles also very conveniently, and drawer type is pumped economizer seemingly.
What more than enumerate only is specific embodiment of the utility model, and obviously, the utility model is not limited to above embodiment.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should belong to protection domain of the present utility model.
