Description
Technical field
The utility model relates to a kind of tube-type air preheater boiler, has especially installed the tube-type air preheater boiler of SCR reactor additional.
Background technology
For meeting the requirement that thermal power plant's air pollution emission standard (GB 1323-2011) controls pollutant emissions such as flue dust, sulfur dioxide, nitrogen oxide and mercury and mercuric compounds, no matter be newly-built coal unit or existing coal unit, all denitrating flue gas will be carried out, to meet environmental requirement.For thermal power plant unit, generally select selective-catalytic-reduction denitrified mode.For newly-built coal-burning power plant, the position of denitration can be considered when boiler design, relatively easily.And for built power plant De-NO_x, it arranges because be subject to the restriction of place and boiler, often more difficult.Especially for the boiler adopting tube-type air preheater, upper economizer, higher level's air preheater, lower economizer, subordinate's air preheater are arranged on same vertical direction, and due to characteristics of compact layout, De-NO_x is more difficult.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of tube-type air preheater boiler installing SCR reactor additional, can install SCR reactor additional on the tube-type air preheater boiler built up.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of tube-type air preheater boiler installing SCR reactor additional, the upper economizer, higher level's air preheater, lower economizer, the subordinate's air preheater that comprise burner hearth and be connected successively with burner hearth; Described upper economizer, higher level's air preheater, lower economizer are arranged on same vertical direction; SCR reactor is arranged on another perpendicular row; Described subordinate air preheater is divided into three strokes, and wherein stroke II, stroke III are arranged on immediately below SCR reactor; The inlet flue duct of SCR reactor is connected with lower economizer; Exhaust pass extends to below lower economizer, and its end is connected with the stroke I of subordinate's air preheater.
Usefulness of the present utility model is: the tube-type air preheater boiler with said structure, is only shifted out by subordinate's air preheater, be arranged in immediately below reactor when installing SCR reactor additional, effectively reduces the layout height of reactor, decreases layout operation.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Mark in figure: economizer, 2 higher level's air preheaters, 3 times economizers, 4SCR reactor, 5 subordinate's air preheaters, 6 stroke I, 7 stroke II, 8 stroke III, 9 exhaust pass, 10 inlet flue ducts, 15 blast pipe II, 16 blast pipe I on 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, the utility model upper economizer 1, higher level's air preheater 2, lower economizer 3, subordinate's air preheater 5 of comprising burner hearth and being connected successively with burner hearth; Described upper economizer 1, higher level's air preheater 2, lower economizer 3 are arranged on same vertical direction; SCR reactor 4 is arranged on another perpendicular row; Described subordinate air preheater 5 is divided into three strokes, and wherein stroke II7, stroke III8 are arranged on immediately below SCR reactor 4; The inlet flue duct 10 of SCR reactor 4 is connected with lower economizer 3; Exhaust pass 9 extends to below lower economizer 3, and its end is connected with the stroke I6 of subordinate air preheater 5.
When work, flue gas is successively by upper economizer 1, higher level's air preheater 2, lower economizer 3, inlet flue duct 10, SCR reactor 4, stroke III8, stroke II7, exhaust pass 9, stroke I6.And cold wind is divided into both sides, gets back to burner hearth after carrying out heat exchange and burn through stroke I6, lower economizer 3, higher level's air preheater 2 by blast pipe I16 successively; Another side by blast pipe II15 come to come stroke III8 after stroke II7 carries out heat exchange again enter exhaust passage 14, burner hearth of finally returning.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
