Abstract
The invention discloses a kind of H type ribbed pipe type economizers of new structure.Including pipe, fin, wearing bush etc.；All pipes use parallel arrangement, and their same one end submission links together for shape so that the inner chamber of all pipes is interconnected；Fin is longitudinally uniform along pipe, and fin surface is perpendicular to pipe axial direction；It is characterized in that fin uniform on the pipe includes two pieces of identical rectangle thin plates, it is evenly equipped with the length direction of two pieces of identical rectangle thin plates consistent with pipe shape of cross section, and the circular groove of equal amount, one side that two pieces of identical rectangle thin plates have circular groove is symmetrically welded on all pipes, being combined into new H type ribbed pipe type coal economizer structures.
Description
Technical field
The present invention relates to a kind of energy saver.Specifically related to a kind of boiler energy recovery technology field, particularly as being a kind of
H type ribbed pipe type economizers in coal-burning boiler burner hearth.
Background technology
The many discharge smoke temperature of power station boiler of current China are higher than design requirement, and reduction exhaust gas temperature is for saving fuel, drop
Low stain has very important practical significance.Therefore in boiler manfacturing industry, raising energy utilization rate coal-fired to save is most of
Ribbed pipe type economizer is both provided with the burner hearth of large medium-size boiler.This ribbed pipe type economizer saves coal with H types ribbed pipe type
Device is most widely used.Traditional H type ribbed pipe types economizer is including being in alternately shape company between parallel arrangement, their same one end
The multiple pipes being connected together so that the intracavity inter-connection of all pipes.Being welded with insertion on the lateral surface of the pipe, its is total
Long helical form fin.Because the fin on pipe is to leave spacing between helical form, the fin on two neighboring pipe so that
The heat exchange area of whole Finned-tube Ecomonizer is smaller, so as to cause heat exchange efficiency relatively low.
The content of the invention
The problem to be solved in the present invention is to provide a kind of H type ribbed pipe type economizers of new structure.This economizer, is changed
Hot area is big, and heat exchange efficiency is high.
The invention solves the problems that above mentioned problem realized by following technical scheme：
A kind of H type ribbed pipe type economizers of new structure of the present invention, it is characterised in that including pipe, fin, wearing bush etc.；Institute
There is pipe to use parallel arrangement, and their same one end submission links together for shape so that the inner chamber phase of all pipes
It is intercommunicated；Fin is longitudinally uniform along pipe, and fin surface is perpendicular to pipe axial direction；It is characterized in that rib uniform on the pipe
Piece includes being evenly equipped with and pipe cross section on two pieces of identical rectangle thin plates, the length direction of two pieces of identical rectangle thin plates
Shape is consistent, and the circular groove of equal amount, and two pieces of identical rectangle thin plates have one side balanced welding of circular groove
It is connected on all pipes, is combined into new H type ribbed pipe type coal economizer structures.
Meeting on the pipe has semicircle wearing bush on cigarette face, longitudinal both sides of semicircle wearing bush have and fin number
Measure the gap structure for being used to install fin being adapted.
The present invention compared with the existing technology, with advantages below：
As can be seen from the above scheme, because all pipes use parallel arrangement, and their same one end submission is replaced
Shape links together so that the inner chamber of all pipes is interconnected；Fin is longitudinally uniform along pipe, and fin surface is perpendicular to pipe
Axially；It is characterized in that fin uniform on the pipe includes two pieces of identical rectangle thin plates, two pieces of identical rectangles
, and the circular groove of equal amount, two piece identicals consistent with pipe shape of cross section are evenly equipped with the length direction of thin plate
One side that rectangle thin plate has circular groove is symmetrically welded and saves coal on all pipes, being combined into new H types ribbed pipe type
Device structure.Because the fin on all pipes on same plane forms as one, the spacing of the fin between adjacent pipe is eliminated,
So as to increase the heat exchange area of whole Finned-tube Ecomonizer, Finned-tube Ecomonizer is improved.
Again semicircle wearing bush is provided with due to meeting on the pipe on cigarette face, it is to avoid the granular substance in flue gas
Abrasion of the body to pipe, so as to extend its service life.
Brief description of the drawings
Fig. 1 is a kind of H type ribbed pipe type economizer partial structural diagrams of new structure of the invention；
Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is new structure H types ribbed pipe type economizer partial structurtes axonometric drawing of the present invention.
Embodiment
To more fully understand the present invention, the present invention is further illustrated with embodiment below in conjunction with the accompanying drawings, but this
The embodiment not limited to this of invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of H type ribbed pipe types economizer of new structure of the invention is included in parallel arrangement
Multiple pipes 2, adjacent pipe 2 links together with one end by bend pipe in alternately shape so that the inner chamber phase of all pipes 2
Connection.The longitudinally outboard of the pipe 2 is evenly equipped with fin 1, and the surface of the fin 1 is longitudinally perpendicular with pipe 2.The fin
1 includes two pieces of identical rectangle thin plates, the longitudinal direction of two panels thin plate have and quantity consistent with all shape of cross sections of pipe 2 and
The equal circular groove of the quantity of pipe 2, the one side of the two panels thin plate with circular groove is symmetrically welded in all pipes 2
On so that the thin plate on same plane on all pipes 2, which forms as one, constitutes H type fins.Due to same on all pipes 2
Thin plate Symmetric Composite in one plane is integrated, and eliminates the fin spacing between adjacent pipe 2, is increased whole gilled tube and is saved coal
The heat exchange area of device, improves the energy-saving efficiency of Finned-tube Ecomonizer.
To avoid abrasion of the granular substance in flue gas to pipe 2, extend the service life of Finned-tube Ecomonizer, in institute
It is semicircle wearing bush 3 to state meeting on pipe 2 and cross section is mounted on cigarette face, and longitudinal both sides of semicircle wearing bush 3 are uniform
There is the breach consistent with the quantity of fin 1, the one side of the thin plate of fin 1 with circular groove is welded by the breach as described in Figure
It is connected on the pipe 2.
