Description
Technical field
The utility model relates to a kind of economizer bent pipe anti-wear device.
Background technology
Economizer is exactly the heating surface of saturation water boiler feedwater be heated in boiler back end ductwork under drum pressure, due to the heat of the low-temperature flue gas that it absorbs, reduce the exhaust gas temperature of flue gas, save the energy, improve efficiency, so be referred to as economizer, economizer is made up of horizontally disposed parallel pipeline, the kink of pipeline is bend pipe, and multiple pipeline is bent to form pipe row.Along with the popularization and application of fluidized-bed combustion boiler, the wear problem of economizer displays increasingly, develop to fin economizer gradually from light pipe economizer, comprise the extensive use on economizer such as spiral fin coil, H type finned tube, this to some extent solves wear problem, and improve heat exchange efficiency, but, finned tube economizer pipe row two ends bend pipe due to the reasons such as processing technology be still light pipe form, this just causes finned tube and is not afraid of wearing and tearing, but light pipe bend pipe is still difficult to solve wearing and tearing, and this problem is very general.Have in prior art and wear strip is arranged on bent portion to reach the technical scheme of abrasionproof effect, the shoe of this structure can not stop flue gas washing away bent portion, can only increase the intensity of bent portion, and abrasionproof effect is bad.In addition, do not support between finned tube, the long-time finned tube that uses may deform, and reduces the service life of economizer.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned defect, provides a kind of flue gas that stops to the economizer bent pipe anti-wear device washing away, avoid pipe bent position wearing and tearing, pipe row firm supporting of pipe bent position.
In order to solve the problems of the technologies described above, the utility model comprises the economizer be arranged between flue inner wall, its design feature is: the both sides of described economizer hand, the opposite nose of bend pipe are separately installed with the side guard plate that can prevent sweep of gases bend pipe, and the top of described economizer is provided with the upper guard board affixed with side guard plate.
Described side guard plate be provided with multiple for pipe row through through hole.
Described every tubulation row is all provided with side guard plate, and each side guard plate is welded as a whole.
One end of described upper guard board is fixed in flue inner wall, and the other end and the side guard plate of upper guard board are affixed.
Flue gas guide plate is installed between described flue inner wall and upper guard board.
Described flue gas guide plate is obliquely installed.
Compared with prior art the utility model has the following advantages: the both sides of economizer hand, the opposite nose of bend pipe are separately installed with side guard plate, side guard plate is provided with through hole, pipe row is arranged in through hole, pipe bent position can be sealed, prevent flue gas washing away pipe bent position, avoid the wearing and tearing of pipe bent position, meanwhile, side guard plate queues the effect supported to pipe, pipe is arranged more firm, not easily deform, extend the service life of economizer; The top of economizer is provided with the upper guard board affixed with side guard plate, upper guard board has the effect of support to side guard plate, can increase the installation strength of side guard plate, and then increases the intensity of the anti-sweep of gases of side guard plate, the abrasionproof effect of further raising pipe bent position, can also extend the service life of side guard plate; Flue gas guide plate is installed between flue inner wall and upper guard board, flue gas guide plate is obliquely installed, and flue gas guide plate has the effect of guiding to flue gas, flue gas is directed to the region between two side guard plates, avoid flue gas washing away pipe bent position further, prevent the wearing and tearing of pipe bent position.
In sum, the utility model structure is simple, effective to the abrasionproof of pipe bent position.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of side guard plate;
Fig. 3 is the annexation figure of economizer and side guard plate;
Fig. 4 be in Fig. 3 A-A to sectional view.
Detailed description of the invention
With reference to accompanying drawing, this economizer bent pipe anti-wear device comprises the economizer 1 be arranged between flue inner wall, in prior art, economizer 1 is made up of horizontally disposed parallel pipeline, the kink of pipeline is bend pipe, multiple pipeline is bent to form pipe row, the arrangement of economizer 1 pipe row has multiple, and the bent portion of pipe row can laterally bend, and also can vertically bend.The both sides of economizer 1 pipe row, the opposite nose of bend pipe are separately installed with the side guard plate 2 that can prevent sweep of gases bend pipe, side guard plate 2 be provided with multiple for pipe row through through hole 21, in the present embodiment, side guard plate 2 is vertically arranged, therefore through hole 21 is vertically distributed on side guard plate 2, and each through hole 21 is corresponding with each pipeline, pipe row is installed in through hole 21, pipe bent position can be made to be in sealing state, thus stop flue gas washing away bent portion, side guard plate 2 can also make pipe row support more firm, not easily deform, extend the service life of economizer.The top of economizer 1 is provided with the upper guard board 4 affixed with side guard plate 2, in the present embodiment, an end of upper guard board 4 is fixed in flue inner wall, the other end of upper guard board 4 and the upper end of side guard plate 2 affixed, upper guard board 4 can increase the installation strength of side guard plate 2, and then increase the intensity of the anti-sweep of gases of side guard plate 2, the abrasionproof effect of further raising pipe bent position, can also extend the service life of side guard plate 2.In the present embodiment, lower backplate also can be installed in the bottom of economizer 1, and lower backplate one end is fixed in flue inner wall, and the bottom of the other end and side guard plate 2 is affixed, increases the installation strength of side guard plate 2 further.
In the present embodiment, every tubulation row is all provided with side guard plate 2, each side guard plate 2 is welded as a whole, and forms the side guard plate 2 that a pipe bent position that is complete, that whole pipe can be arranged seals, thus makes the pipe bent position of whole economizer reach good abrasionproof effect.
With reference to accompanying drawing 1, flue gas guide plate 3 is installed between flue inner wall and upper guard board 4.One end of flue gas guide plate 3 is fixed in flue inner wall, the other end of flue gas guide plate 3 is welded on upper guard board 4, in the present embodiment, the other end of flue gas guide plate 3 is welded on one end that upper guard board 4 is connected with side guard plate 2, flue gas guide plate 3 so just can be made to be in heeling condition, thus flue gas is played to the effect of guiding, flue gas is directed to the region between two side guard plates 2, avoids flue gas washing away pipe bent position further, prevent the wearing and tearing of pipe bent position.
The utility model is not limited to above-mentioned detailed description of the invention, those skilled in the art, under the prerequisite not departing from spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
