Abstract
A kind of boiler H type fin economizer erecting by overhang, it relates to a kind of erecting by overhang.It is very large that the utility model solves taking up room of existing hanging form of tubes existence, and the dismounting that can not meet requirement and the pipe clamp type form existence arranging denitrification apparatus requisite space is inconvenient, and during dismounting, pipe clamp is fragile, the problem that cost is high.The top of each boatswain chair is all processed with first installing hole, the top of each first steel plate is all processed with second installing hole, the uniform processing of lower horizontal three the 4th installing holes of each first steel plate, each second steel plate is all processed with the 3rd installing hole, two the first steel plates overlap and arrange, the top of each boatswain chair is arranged between two the first steel plates by a bearing pin, be provided with second steel plate between each boatswain chair and the first steel plate, the two side of each described boatswain chair is all welded with square steel.Boiler H type fin economizer erecting by overhang of the present utility model is used for the hanging of boiler economizer.
Description
Technical field
The utility model relates to a kind of boiler economizer erecting by overhang.
Background technology
Along with the raising day by day of living standard, developing rapidly of modern science and technology, people are for the enhancing of environmental protection consciousness, and the environment of supportive protection energetically of country in addition, the environmental requirement of the aspect of boiler operatiopn is more and more higher, and present stage desulphurization denitration transformation becomes more consummate day by day.Wherein denitration transformation is that requirement boiler tail headspace is very large, so just greatly improves the requirement of boiler improvement.Modally in boiler improvement exactly light pipe economizer is transformed into H type fin economizer to save space, reduces denitration improvement cost.
Existing fin economizer hanging adopts hanging form of tubes or pipe clamp form, adopts hanging form of tubes to take up room very large, can not meet the requirement arranging denitrification apparatus requisite space.
The fixed form of another kind of pipe clamp form is that band steel is made pipe clamp, band steel is directly welded on ventilation beam again, and the hanging dismounting of this mode is inconvenient, has damaged pipe clamp during dismounting, again can not weld, the requirement of the cost of investment reducing boiler improvement in denitration transformation can not be met.
Utility model content
The utility model is that taking up room of solution existing hanging form of tubes existence is very large, the dismounting that can not meet requirement and the pipe clamp type form existence arranging denitrification apparatus requisite space is inconvenient, during dismounting, pipe clamp is fragile, the problem that cost is high, and then provide a kind of boiler H type fin economizer erecting by overhang.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of boiler H type fin economizer erecting by overhang, comprise three boatswain chairs, three bearing pins, two the first steel plates, six the second steel plates and six square steel, it is characterized in that: the thickness range of each boatswain chair is 6 ~ 10mm, the top of each boatswain chair is all processed with first installing hole, the top of each first steel plate is all processed with second installing hole, the uniform processing of lower horizontal three the 4th installing holes of each first steel plate, each second steel plate is all processed with the 3rd installing hole, two the first steel plates overlap and arrange, the top of each boatswain chair is arranged between two the first steel plates by a bearing pin, second steel plate is provided with between each boatswain chair and the first steel plate, the two side of each described boatswain chair is all welded with square steel.
The beneficial effects of the utility model are:
One, the thickness range of boatswain chair is 6 ~ 10mm, just can install between fin, space occupied by former pipe clamp arranges H type economizer fin now, add heating surface area, compared with hanging with existing H type economizer, length direction is saved space and is about about 1 meter, more easily meet the space needed for denitrification apparatus, in also making denitration transform, the improvement cost of boiler part reduces simultaneously;
Two, all use pinned connection by the connection of the first steel plate between boatswain chair and header or shaped steel, overhauling or occurring dismantling when damaging more convenient compared with existing erecting by overhang, erecting by overhang and pipe clamp can not be damaged, reduce cost of investment.

Fig. 1 is the front view of erecting by overhang of the present utility model, Fig. 2 is the left view of Fig. 1, and Fig. 3 is the front view of boatswain chair 1 of the present utility model, and Fig. 4 is the left view of Fig. 3, Fig. 5 is the front view of the first steel plate 3 in the utility model, and Fig. 6 is the front view of the second steel plate 4 of the present utility model.
Detailed description of the invention
Detailed description of the invention one: as shown in figs. 1 to 6, the boiler H type fin economizer erecting by overhang of present embodiment, comprise three boatswain chairs 1, three bearing pins 2, two the first steel plates 3, six the second steel plates 4 and six square steel 5, it is characterized in that: the thickness range of each boatswain chair 1 is 6 ~ 10mm, the top of each boatswain chair 1 is all processed with first installing hole 6, the top of each first steel plate 3 is all processed with second installing hole 7, the uniform processing of lower horizontal three the 4th installing holes 9 of each first steel plate 3, each second steel plate 4 is all processed with the 3rd installing hole 8, two the first steel plates 3 overlap and arrange, the top of each boatswain chair 1 is arranged between two the first steel plates 3 by a bearing pin 2, second steel plate 4 is provided with between each boatswain chair 1 and the first steel plate 3, the two side of each described boatswain chair 1 is all welded with square steel 5.Finned tube is lifted on together by boatswain chair 1, with square steel 5 by finned tube shutoff in the tube seat of boatswain chair 1, make finned tube can not depart from boatswain chair 1 due to vibration, ensure that H type fin economizer is operationally more stable, the upper end of the first steel plate 3 and the otic placode of header or shaped steel are rotationally connected by bearing pin.
Detailed description of the invention two: composition graphs 3 illustrates present embodiment, boatswain chair 1 described in present embodiment is bilateral symmetry, the both sides of boatswain chair 1 are uniform is along its length processed with two line pipe grooves, the profile of each tube seat comprises rectilinear segments and circular arc shaped portion, and described rectilinear segments is with respect to the horizontal plane inclined upwardly 24-30 degree.Other step is identical with detailed description of the invention one.
