Abstract
The utility model belongs to a kind of outer circulation chimney for wet flue gas desulfurization, be characterized in: at the bottom of chimney, side is provided with outlet pipe, circulating water pool is provided with outside chimney, circulating water pool is connected with outlet pipe, inside at the bottom of flue, be laterally provided with boss, intrinsic 2 row's showers on boss, often row has 2-4 root, every root shower is evenly equipped with 4-6 individual event spiral nozzle.This chimney has the advantage of former chimney for wet flue gas desulfurization, not only can desulfurization but also can discharge fume, desulfuration efficiency can reach more than 90%, utilizes existing flue, quantities is little, small investment, does not change former chimney raft load, chimney foundation safety, construction environment is good, operating efficiency is high, is convenient to maintenance and deslagging, is suitable for sintering machine, thermal power plant and the newly-built chimney of large-scale kiln or transforms old chimney using.
Description
Technical field
The utility model relates to kiln chimney, is the outer circulation chimney for wet flue gas desulfurization that a kind of sintering machine, thermal power plant and large-scale kiln use.
Background technology
At present, the chimney that sintering machine and large-sized industrial kiln use, it is all single smoke discharging function, enterprise is in order to give flue gas desulfurization, in former smoke evacuation system, desulphurization system that is a set of and the equal air quantity of chimney need be increased again, desulfurizing tower diameter is substantially identical with section diameter at the bottom of chimney, newly-built desulfurizing tower, investment is many, floor space is large, two cover systems are also deposited, not only affect site environment but also cause waste, in 2010, Chinese patent publication, disclose one " chimney for wet flue gas desulfurization ", this chimney not only can desulfurization but also can discharge fume, desulfuration efficiency can reach more than 90%, but, this chimney structure has shortcoming: one is that former flue entrance need be raised, again flue to be transformed, perforate wanted by chimney, reinforce, the workloads such as Strength Calculation are large, long construction period, two is that circulating water pool is located in chimney, and former chimney raft load can increase, and relevant device installation environment is bad, and workload is large, inefficiency, if there is water to leak the safety that also can have influence on chimney foundation.
Summary of the invention
The purpose of this utility model is to provide a kind of outer circulation chimney for wet flue gas desulfurization, need raise to solve existing chimney for wet flue gas desulfurization flue entrance, again to transform flue, chimney be wanted the workloads such as perforate, reinforcing, Strength Calculation large, long construction period; Two be circulating water pool in chimney, former chimney raft load can increase, and relevant device installation environment is bad, and workload is large, inefficiency, if there is water to leak the problem that also can have influence on the safety of chimney foundation.
The purpose of this utility model is achieved in that this chimney is made up of flue, individual event spiral nozzle, shower, chimney, lining, atomising device, dehydration demister, Bidirectional spray head, cleaning hose, operating platform, manhole, cat ladder, circulating water pipe, clear water pipe, inspection door, at the bottom of chimney, side is provided with outlet pipe, circulating water pool is provided with outside chimney, circulating water pool is connected with outlet pipe, inside at the bottom of flue, laterally be provided with boss, intrinsic shower on boss.
Boss is trapezoidal, and height is 800-1300mm.
Shower has two rows, and often row has 2-4 root, every root shower is evenly equipped with 4-6 individual event spiral nozzle.
This utility model compared with prior art has the following advantages: 1) utilize existing flue, quantities is little, saves flue duct retrofit, chimney perforate, reinforcing, calculating, engineering time and fund; 2) circulating water pool is outside chimney, does not change former chimney raft load, chimney foundation safety, and construction environment is bad, and operating efficiency is high, is convenient to maintenance and deslagging; 3) this chimney has the advantage of existing chimney for wet flue gas desulfurization.
Accompanying drawing explanation
Fig. 1 outer circulation chimney for wet flue gas desulfurization structural representation.
Detailed description of the invention
In figure: flue 1, shower 3, individual event spiral nozzle 4, chimney 5, lining 6, atomising device 7, dehydration demister 8, Bidirectional spray head 9, cleaning hose 10, manhole 11, operating platform 12, cat ladder 13, circulating water pipe 15, clear water pipe 14, inspection door 16 is all same as the prior art, difference is: be provided with outlet pipe 17 in side, chimney 5 end, circulating water pool 19 is provided with outside chimney, circulating water pool is connected with outlet pipe 17, inside at the bottom of flue, laterally be provided with boss 2, boss is trapezoidal, height is 800-1300mm, intrinsic 2 row's showers 3 above, often row has 2-4 root, every root shower is evenly equipped with 4-6 individual event spiral nozzle 4, the recirculated water of ejection is identical with flue gas flow direction, not only can cooled flue gas but also can desulfurization, shower 3 and atomising device 7 all adopt recirculated water 18, recirculated water adopts limewash or soda water, supplied through circulating water pipe 15 by buck pump, cleaning hose 10 adopts clear water, supplied through clear water pipe 14 by water pump.
