Abstract
The utility model discloses a structure is disturbed to low flow resistance for flue gas denitration concurrent heating system, this structure includes flue gas flue collector and a plurality of low resistance vortex spare promptly, a plurality of low resistance vortex spare in bank intervals are located in the flue gas flue collector. This structure has effectively improved flow field and the temperature homogeneity of flue gas in the flue in the flue gas concurrent heating system, satisfies the denitration technological requirement, has improved equipment life and flue gas denitration effect.
Description
Technical field
This utility model relates to the denitrating flue gas of sintering or coke oven, particularly relates to a kind of low flow resistance for denitrating flue gas concurrent heating system and disturbs structure.
Background technology
In recent years, constantly perfect along with the increasingly stringent of national environmental standard and Air Pollution prevention and control legislative measure, the standard limit of smog release of sintering or coke oven is more harsh. And the fume emission present situation according to domestic sintering or coke oven, NOx emission does not reach relevant criterion. Generally adopting SCR denitration technique that flue gas is carried out post processing at present, SCR denitration requires that technological temperature is 180��400 DEG C, higher than sintering or coke oven technique smog discharge temperature. It is thus desirable to arrange the concurrent heating system of flue gas, owing to the flue sectional area of sintering or coke oven is bigger so that concurrent heating flue gas accounting original system exhaust gas volumn is less, and SCR denitration technological requirement processes flue gas flow field uniformly, and section temperature difference is within 10 DEG C.
At present in flue gas concurrent heating system, high heating value gas is generally adopted and directly arranges fire disc type burner in flue; Middle low-heat value gas is generally adopted sets up afterburning furnace, adopts sudden expansion or cannula type that flue gas is sent into the purpose being reached for flue gas concurrent heating in flue. This two ways is all difficult meets the requirement that after concurrent heating, flue gas flow field is uniform, temperature homogeneity is good, thus shortening the denitration subsequent process equipment life-span, reducing the denitration effect of flue gas.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of low flow resistance for denitrating flue gas concurrent heating system and disturbs structure, flow field that this structure is effectively increased in flue gas concurrent heating system flue gas in flue and temperature homogeneity, meet denitrating technique requirement, improve service life of equipment and denitrating flue gas effect.
For solving above-mentioned technical problem, this utility model is disturbed structure for the low flow resistance of denitrating flue gas concurrent heating system and is included flue gas flue collector and some low-resistance flow-disturbing parts, and described some low-resistance flow-disturbing parts interval in a row is located in described flue gas flue collector.
Further, described some low-resistance flow-disturbing parts at least become two row intervals to be located in described flue gas flue collector, and the low-resistance flow-disturbing number of packages amount often arranged is more than the injection port of high-temperature flue gas in described flue gas flue collector, low-resistance flow-disturbing part interlaced arrangement between row and row.
Further, described some low-resistance flow-disturbing parts are in described flue gas flue collector above high-temperature flue gas injection port between 1��10 meter.
Further, described low-resistance flow-disturbing part is cylinder or the crossed body of inverted cone.
Disturbing structure due to this utility model for the low flow resistance of denitrating flue gas concurrent heating system and have employed technique scheme, namely this structure includes flue gas flue collector and some low-resistance flow-disturbing parts, and described some low-resistance flow-disturbing parts interval in a row is located in described flue gas flue collector. Flow field that this structure is effectively increased in flue gas concurrent heating system flue gas in flue and temperature homogeneity, meet denitrating technique requirement, improve service life of equipment and denitrating flue gas effect.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail:
Fig. 1 is this utility model disturbs structural representation for the low flow resistance of denitrating flue gas concurrent heating system.
Detailed description of the invention
Embodiment includes flue gas flue collector 1 and some low-resistance flow-disturbing parts 2 as it is shown in figure 1, this utility model disturbs structure for the low flow resistance of denitrating flue gas concurrent heating system, and described some low-resistance flow-disturbing part 2 intervals in a row are located in described flue gas flue collector 1.
Preferably, described some low-resistance flow-disturbing parts 2 at least become two row intervals to be located in described flue gas flue collector 1, and low-resistance flow-disturbing part 2 quantity often arranged is more than the injection port of high-temperature flue gas in described flue gas flue collector 1, low-resistance flow-disturbing part 2 interlaced arrangement between row and row.
Preferably, described some low-resistance flow-disturbing parts 2 are in described flue gas flue collector 1 above high-temperature flue gas injection port between 1��10 meter.
Preferably, described low-resistance flow-disturbing part 2 can adopt cylinder or the crossed body of inverted cone. Inverted cone is relative to its bottom surface of flat board with level at an angle so that the fluid resistance of flue gas is less, and the mixing of whole flue gas section fluid is more uniform, and the flue gas section temperature difference is less.
When the flue gas of sintering or coke oven enters after flue gas flue collector through the injection port of flue gas flue collector through concurrent heating system, some low-resistance flow-disturbing parts that high-temperature flue gas is set in a row by this structure realize low-resistance flow-disturbing, make in flue collector heavy in section flue gas rapidly, be sufficiently mixed, improve the flow field uniformity of flue gas in flue collector, reduce the temperature difference in flue gas cross section, it is effectively improved the denitration effect of flue gas, extends the service life of denitration subsequent process equipment; Meanwhile, flue gas rapid, be sufficiently mixed and can effectively shorten the length of smoke mixing section in flue collector, thus reducing the construction investment of denitration device, reduce production cost.
