Description
Technical field:
The utility model relates to the tapping equipment of processing back, a kind of Coal,steam plant with FGD system absorption tower flue gas, is specifically related to a kind of transformation desulfuration chimney tapping equipment.
Background technology:
Country controlled relatively strictlyer with regard to thermal power plant SO2 discharge index amount in recent years, and the power plant that does not originally establish desulfurizer all need append.And the limestone-gypsum wet desulfurizing process has become the first-selected technology of Power Plant in China flue gas desulfurization, and has adopted the wet fuel gas desulfurizing technology of no GGH mostly because of it has that the desulfurizing agent low in raw material cost is easy to get, desulfuration efficiency height, technology maturation, reliable.About 56 ℃ of absorption tower exit gas temperature, under this low temperature, the clean flue-gas temperature after the desulfurization is lower than flue gas acid dew point; Contain easy condensations such as saturated water vapour, SO2, SO3 in the flue gas and produce corrosive sulfuric acid and sulfurous acid solution; Flue behind the absorption tower and chimney are had very strong corrosivity, therefore must to original chimney of power plant promptly main chimney carry out anticorrosion transformation, during transforming; It is desulfuration chimney that one alternative fume extractor need be set, to guarantee the normal operation of unit.
The utility model content:
The purpose of the utility model provides a kind of transformation desulfuration chimney tapping equipment; It is simple in structure; Easy to maintenance; Basically do not increase power-equipment, realized energy-conserving and environment-protective, solved in limestone-gypsum wet desulphurization master chimney anticorrosion transformation or make regular check on and do not influence the continuously technical problem that need discharge of operation and desulfurization flue gas of host groups.
In order to solve the existing problem of background technology, the utility model is to adopt following technical scheme: it comprises absorption tower 1, steelframe 2, threeway 3, expansion joint 5, oblique zip 6, support ear seat 7, desulfuration chimney 8, guide lugs seat 9; Steelframe 2 is fixed on the absorption tower 1; Threeway 3 is arranged on the top on absorption tower 1, and steelframe 2 is provided with the sandwich construction beam, and is respectively arranged with support ear seat 7 and guide lugs seat 9 on the second layer structural beams therein; Gas baffle door 4 is housed in the threeway 3; Desulfuration chimney 8 is fixed on steelframe 2 through support ear seat 7 and guide lugs seat 9, and tiltedly zip 6 is arranged on the beam column construction of desulfuration chimney 8, and desulfuration chimney 8 links to each other through expansion joint 5 with gas baffle door 4.
Described desulfuration chimney 8 is a carbon steel matter desulfuration chimney.
Described threeway 3 is the threeway of carbon steel matter.
The inwall of described desulfuration chimney 8 is provided with anticorrosive coat 8-1.
The inwall of described threeway 3 is provided with anticorrosive coat 3-1.
The cross section of described desulfuration chimney 8 is circular.
Described threeway 3 forms for unit absorbs the transformation of tower top outlet smoke canal elbow.
The utlity model has following beneficial effect:
1, the utility model gas flowfield is smooth and easy, and resistance is less, and it is both economical and safe that operation is in a short time used.Though the height of desulfuration chimney aspect ratio master chimney is low; Atmosphere hoist height is not as former chimney; But clean SO2 concentration of flue gas and dust concentration after the desulfuration chimney discharging desulfurization are lower; The flue gas flow rate of outlet is also bigger, therefore can not produce bigger influence to the atmospheric environment of location, is comparatively ideal facility.
2, the utility model is built in because of desulfuration chimney and is absorbed on the cat head, and the condensate in the chimney will be back in the absorption tower with the mode of gravity flow, thereby needn't establish condensed-water recovering device and pipeline more in addition, and is simple and reasonable.
3, the utility model structure stress is reasonable.Adopt beam column construction and suspension cable structure in this programme, share effective and reasonablely and decomposed the load of desulfuration chimney and stressed, improved the force-bearing situation of desulfuration chimney and absorption tower tower body to greatest extent, make the stressed more safe and reliable of the two.
4, the setting of the utility model desulfuration chimney makes main chimney anticorrosion not receive the influence of construction period, can guarantee main chimney anticorrosion construction quality, has avoided shutting down the economic loss that is caused again.
5, the utility model is that effective convenience has been created in main chimney lining anticorrosive coat inspection.
