The utility model discloses evenly desulfurization flue gas flow field, temperature field, speed field and pressure field can and be overhauld for the installation of desulfurization in future electricity defogging, change again and provided operation platform, and be one may well say that at one stroke multi -purpose.
Description
Technical field
The utility model relates to smoke discharging device applied technical field, especially a kind of flue gas even distribution device.
Background technology
The energy consumption per unit that China " 12 " planning outline proposes declines 16%, and CO2 emission reduces by 17%, and total emissions of major pollutants reduces 8-10%.
" 12 " are the critical periods of China's socio-economic development transition, realize low carbon development, Green Development is the theme that " 12 " are developed.But due to the particularity of China's energy resource structure, within considerable time, can not there is essence change in the primary energy supply pattern based on coal.Generally speaking, " 12 " period, energy demand also can keep the situation grown at top speed, according to State Grid's project study center about " the medium-term and long-term generating capacity of China and electricity needs development prediction ", by the end of the year 2013, China's coal electricity installed capacity will be 8.47 hundred million kilowatts.Prediction the year two thousand thirty coal Denso machine 12.5-14 hundred million kilowatts; The year two thousand fifty coal Denso machine 14-15 hundred million kilowatts.Large-scale coal fired power generation can bring than now more serious environmental problem.
The coal-burning boiler of current all parts of the country all maybe will add desulfurizer, wherein more than 90% is wet desulphurization device, the object of desulfurization own removes pollutants in air SO2, improve air quality, but the wet flue gas fog that desulfurization Wet chimney is discharged is very large, misunderstanding is caused to neighbouring resident, think that this is dense smoke, moreover the flue gas hangover had is very long, the living environment of significantly affecting local resident.In addition, its desulfurization " gypsum rain " phenomenon is a national difficult problem now, the gypsum rain (mainly being carried secretly by droplet) that desulfurizing tower is discharged descends slowly and lightly to the vegetable plot of peasant, the windowsill balcony etc. of resident, brings the inconvenience of life, also often suffer the complaint of local resident to local resident.
Wet type electric demister can remove the droplet in flue gas effectively, eliminates " gypsum rain " phenomenon, can also reduce PM2.5 dust, SO3 and the pollutant such as mercury and oxide thereof, having a extensive future of coal-burning power plant of China simultaneously.
Prior art is difficult to the needs of people, in order to solve above-mentioned Problems existing, the utility model proposes a kind of flue gas even distribution device.
For realizing this technical purpose, the technical solution adopted in the utility model is: a kind of flue gas even distribution device, comprises flue gas rectification grid, support ring, brace summer and fixture; Described flue gas rectification grid is fixed on brace summer upper end by fixture; Described support ring is arranged on flue gas rectification grid bottom, and described support ring is fixed on inside former flue gas smoke exhaust pipe.
Further, described flue gas rectification grid is at brace summer interval 20-40mm.
Further, described brace summer adopts finished product rectangle box beam.
Further, flue gas flow straightening grid material is the straight plate of PP.
Further, support ring is annulus, is welded in wet electric tower wall, ring flat-plate thickness 8-10mm, width 200mm.
Further, brace summer material is ordinary carbon steel, outside brushing glass flake or line with rubber.
Compared with prior art, the utility model has following beneficial effect: this flue gas even distribution device, can evenly desulfurization fume flow field, temperature field, velocity field and pressure field, can install for the demist of desulfurization in future electricity again, to change and maintenance provide operating platform, be multiplex at one stroke.Global design is novel, practical, is easy to promote the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Figure of description 1-4, in the utility model embodiment, a kind of flue gas even distribution device, comprises flue gas rectification grid 2, support ring 3, brace summer 4 and fixture 5; Described flue gas rectification grid 2 is fixed on brace summer 4 upper end by fixture 5; Described support ring 3 is arranged on flue gas rectification grid 2 bottom, and described support ring 3 is fixed on inside former flue gas smoke exhaust pipe; Described flue gas rectification grid 2 is at brace summer 4 interval 20-40mm.
Embodiment: the flue gas through desulfurizing tower process is saturated wet flue gas, the about 75mg/Nm3 of droplet content of its flue gas, flue-gas temperature ~ 50 DEG C, under this operating mode, saturated wet flue gas is from bottom to top by flue gas cool-down atomizing layer, flue gas even distribution plate, anode (honeycomb) tube module, and the flue gas droplet content≤25mg/Nm3 after finally processing discharges from electric demist top.Flue gas flow straightening grid material is the straight plate of PP, heatproof 80 DEG C, resistance to flue gas corrosion, is applicable to wet desulfurization flue gas medium.PP straight plate width 150-200mm, wall thickness 2-3mm, length is cutting as required.Spacing 20-40mm between plate and plate.PP plate utilizes horizontal bar to connect, the polylith rectangle block-wise module of composition width about 1 meter, is convenient to from wet electric installing hole turnover.Brace summer, for supporting flow straightening grid module, adopts finished product rectangle box beam, according to wet electric diameter and amount of deflection, sectional dimension and wall thickness require that calculating is determined.Brace summer material is ordinary carbon steel, outside brushing glass flake or line with rubber, heatproof 100 DEG C.Support ring is for supporting flow straightening grid module, and support ring is annulus, and be welded in wet electric tower wall, ring flat-plate thickness 8-10mm, width is about 200mm, contour with brace summer, outside brushing glass flake, heatproof 100 DEG C.Ring flat-plate material is ordinary carbon steel.Fixture, for flow straightening grid module is fixed on brace summer, prevents flow straightening grid module from sliding and falls.Fixture equal leg angle makes, and material is ordinary carbon steel, and angle steel top has bolt hole (for stuck-module), and angle steel itself is welded on brace summer, outside brushing glass flake, heatproof 100 DEG C.
The above; be only preferred embodiment of the present utility model; not in order to limit the utility model, every above embodiment is done according to technical spirit of the present utility model any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solutions of the utility model.
