Description
Technical field
A kind of desulfuration chimney is the utility model is related to, especially a kind of novel desulphurization denitration chimney.
Background technology
Under the policy situation that environmental requirement steps up, some old power plant, which are faced with, carries out asking for desulphurization denitration transformation
Topic, new power plant construction will also design desulphurization denitration simultaneously, and conventional desulfurization technique is wet desulphurization, be entered by air-introduced machine exhaust pass de-
Sulphur tower, the flue gas after desulfurization enter chimney through fiber glass reinforced plastic smoke flue again by desulfurizing tower.Although this arrangement is than more conventional, operation
It is stable, but for the limited old factory site in transformation place or the nervous newly-built factory site in place is built, it is difficult according to conventional arrangement
Realize, desulphurization denitration tower and chimney integral structure can solve this problem very well.
Utility model content
Technical assignment of the present utility model is to be directed to above the deficiencies in the prior art, and provides a kind of novel desulphurization denitration cigarette
Chimney.
Technical scheme is used by the utility model solves its technical problem：A kind of novel desulphurization denitration chimney, wherein
Including desulfurizing tower and chimney, the desulfurizing tower is located at the lower section of chimney, expansion joint is provided between the desulfurizing tower and chimney, in institute
State desulfurizing tower and be externally provided with steel structure support with chimney, the expansion joint is respectively by fluorubber, alkali-free glass fiber cloth, polytetrafluoroethyl-ne
Alkene film and stainless steel cloth composition.
Further improve：A diameter of 7.2m of the desulfurizing tower, high 45m, wall thickness 35m, a diameter of 3.8m of chimney are high
For 55m, 28m.
Further improve：The desulfurizing tower is made with chimney of glass-reinforced plastic material.
Further improve：The expansion joint is followed successively by the thick alkali-free glass of the thick fluorubber of 2.5mm, 1.7mm from inside to outside
Fiber cloth, the polytetrafluoroethylene film of 0.3mm thickness, the alkali-free glass fiber cloth of 1.7mm thickness, 0.3mm thick polytetrafluoroethylene (PTFE) is thin
Film, the fluorubber of 2.5mm thickness, 0.25mm thick stainless steel cloth.
The advantages of the utility model：Sulphur denitrating tower and chimney integral structure have function concentration, flexible arrangement, save
Land used, save fund the advantages that, and according to different situations may be selected high-low position arrangement.For the newly-built of place and financial strain
Power plant and the transformation of old power plant desulfurization provide more preferable selection.Desulphurization denitration tower and chimney integral structure simplify technique, carry
High utilization of area rate and construction speed, there is positive meaning for power plant design from now on and construction.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the top view of the utility model expansion joint.
Fig. 3 is the sectional view in A-A directions in the utility model Fig. 2.
Embodiment
The utility model is described below with reference to Figure of description.
As illustrated, a kind of novel desulphurization denitration chimney, including desulfurizing tower 2 and chimney 4, the desulfurizing tower 2 is located at
The lower section of chimney 4, expansion joint 3 is provided between the desulfurizing tower 2 and chimney 4, steel knot is externally provided with the desulfurizing tower 2 and chimney 4
Structure support 1, the expansion joint 3 is respectively by fluorubber 31, alkali-free glass fiber cloth 32, polytetrafluoroethylene film 33 and stainless steel wire
Net 34 forms；A diameter of 7.2m of the desulfurizing tower 2, high 45m, wall thickness 35m, a diameter of 3.8m of chimney 4, a height of 55m,
28m；The desulfurizing tower 2 is made with chimney 4 of glass-reinforced plastic material；The expansion joint 3 is followed successively by 2.5mm thickness from inside to outside
Fluorubber 31, the alkali-free glass fiber cloth 32 of 1.7mm thickness, the polytetrafluoroethylene film 33 of 0.3mm thickness, 1.7mm thick alkali-free glass
Glass fiber cloth 32, the polytetrafluoroethylene film 33 of 0.3mm thickness, the fluorubber 31 of 2.5mm thickness, 0.25mm thick stainless steel cloth
34。
Its operation principle：Desulfurizing tower 2 is connected with chimney 4 using fluorubber expansion joint, and expansion joint 3 can adjust desulfurizing tower 2
With chimney 4 due to vertical displacement caused by temperature change, and reduce influence of the vibrations to top chimney 4 when desulfurizing tower 2 is run.Place
Consider in waterproof, 2 whole altitude range of desulfurizing tower does not set expansion joint 3.Each setting two in altitude range of desulfurizing tower 2 and chimney 4
It is individual only to shake platform, prevent that the horizontal displacement in wind action lower shell is excessive；Outside desulfurizing tower 2 and the integral structure of chimney 4
Support uses steel structure support 1, and structural system is bracing members-frame system, and steel structure support 1 uses cylindrical steel tube, fiberglass
Chimney wall thickness 28mm, using suspended structure, load-bearing position absolute altitude 105m, load about 35t.The wall thickness 35mm of desulfurizing tower 2, to support oneself
Formula, steel structure support 1 meet bearing capacity and shockproof requirements, and steelframe anti-corrosion uses the preferably overall zincincation of antiseptic effect, examined
Consider work high above the ground factor, be connected between rod member and be connected by screw bolts；Because fiberglass has price relatively low and performance
The advantage such as stable, compares through Practical Project, and desulfurizing tower 2 and the integral structure of chimney 4 and the sleeve-type chimney of same height are in work
It is more or less the same in journey investment, construction investment is significantly less than the scheme of conventional desulfurizing tower, denitration building plus sleeve-type chimney.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
