Description
Technical field
The invention belongs to mechanical preparation field, be specifically related to a kind of Industrial Boiler water conservancy diversion template fiberglass desulfurization cigarette tower.
Background technology
" nicotinic acids " technology is defined as cancelling conventional boiler chimney in engineering practice in the past, by the mode that chimney and cooling tower unite two into one, cooling tower is made both to have kept original cooling heat dissipation function, replace the boiler smoke of smoke stack emission after desulfurization again, this technology is only applicable to the newly-built big-and-middle-sized thermal power plant arranging cooling tower equipment.
For the enterprise having mediumand smallscale industrial boilers, because not establishing cooling tower equipment, cannot realize chimney-cooling tower and uniting two into one, the object of cost efficiency is difficult to realize.In newly constructed boiler unit Synchronization Design flue gas desulphurization system or original boiler controller system FGD process, by the version adopting desulfuration absorbing tower and boiler exhaust gas chimney to unite two into one, impart the definition that " nicotinic acids " technology is brand-new.The type cigarette tower adopts fiberglass reinforced plastics, be commonly called as fiberglass (FRP or GRP), it is the composite by glass fibre and resin compounded, intensity and rigidity is provided by glass fibre, resin provides chemical resistance and toughness, possess the quite sour antiseptic property with titanium steel plate, can heat-insulation layer be cancelled, be particularly suitable for the Wet chimney service condition that Desulphurization for Coal-fired Power Plant does not add GGH.
The unite two into one operation principle of device of desulfuration absorbing tower and chimney is, first fire coal boiler fume enters the absorption tower of bottom through air-introduced machine, the slurries at spraying layer place spray and lower mixing with flue gas from bottom to top realize desulfurization after nozzle atomization, the flue gas after desulfurization through top chimney lifting by being discharged into air after the condensate water recovery device of chimney top.
The relatively traditional desulfur technology form of " nicotinic acids " technology, has following characteristics.
(1) project occupation of land area is saved.When carrying out entire system layout, without the need to the clean flue gas after desulphurization reaction is introduced original old chimney, namely without the need to considering the place trend of clean flue gas flue after desulfurization, closely can arrange the layout of equipment, system footprint area can save 20 more than %.
(2) reasonably optimizing system configuration, reduces engineering investment cost.Because clean flue gas directly discharges through absorption tower, compare with traditional desulfur technology, eliminate equipment or the materials such as supporting gas baffle door, the main material of flue, flue material, saved initial investment cost, and simplified the operation control logic of equipment start-stop in system to a certain extent.
(3) existing facility transformation time cost and risk cost is reduced.At present, domestic flue gas desulfurization project does not generally arrange flue gas heat-exchange unit (GGH).Therefore, newly constructed boiler unit need possess the chimney of corrosion proof function, and old unit then will carry out anticorrosion transformation to original old chimney.
(4) effective reduction system day-to-day operation energy consumption.Because of without the need to arranging clean flue gas flue after desulfurization, the desulphurization system pressure loss effectively can reduce by 500 ~ 700Pa, and system saving power consumption per hour is more than 100
.
(5) middle-size and small-size newly-built, transformation project is widely used in." nicotinic acids " technology, by the combination with the wet desulphurization main reaction technique such as limestone-gypsum method, magnesium processes, sodium method, seawater method, can be widely used in middle-size and small-size newly-built, transformation project, reach reduce to take up an area, the object of investment reduction.
Although " nicotinic acids " technology shows a lot of advantage when being used for middle and small burn coal boiler flue gas desulfurization, but existing based on " nicotinic acids " technology if do not carried out wet flue gas drying, condensed water precipitation will be faced and affect the series of problems such as surrounding enviroment, if adopt lime stone as desulphurization reaction absorbent, then may there is " gypsum rain " phenomenon at plant area's periphery.For head it off, the people such as Wei Yu propose to install one-piece type chimney condensation water recovery system additional, and condensing hot air furnace process was divided into for 3 stages carried out.
1st stage saturated flue gas forms active force through swirl-flow devices in the normal direction of flow of flue gas, makes most of condensed water make a concerted effort to affect by chimney lifting and normal force and flow to inner wall of stack; In 2nd stage, by the hole of the condensed water after the 1st stage through inner wall of stack, be back to inside, absorption tower by diversion pipeline; In 3rd stage, less the adding along the condensed water that inner wall of stack goes upward to chimney top by lifting effect of a small amount of particle diameter contacts with external environment condition and the condensed water of separating out, and after collected overhead device, is back to inside, absorption tower recycles by diversion pipeline.In addition, the discharge standard that meet increasingly stringent also needs improves desulfuration efficiency further.Trace it to its cause, this technology desulfurizing tower many employings wet sprinkling tower, in tower, the Flow Field Distribution of flue gas and slurries directly decides mass transfer in tower, heat transfer and reaction and carries out, and particularly the flow behavior of flue gas directly has influence on the determination of cigarette tower physical dimension and the arrangement etc. of tower inner nozzle quantity, burner design and nozzle.
Actual motion shows, the key factor affecting wet process of FGD efficiency is flow field complicated in tower.For spray column, be only difficult to disclose the mobility status in tower by test, and numerical simulation plays important effect at understanding spray column Regularity of Smoke Movement and design aspect.North China Electric Power University Wang Xu, by carrying out rational modelling and simplification to large desulfurization tower, adopts business software Fluent to carry out Two-dimensional numerical simulation to wet desulphurization vertical spray tower void tower, and result of calculation display void tower flow field Velocity Profiles is uneven.Zhejiang University woods Yongming is by commercial Fluent software, numerical simulation has been carried out for flue gas flow field in 300MW unit wet method fume desulfurizing system spray column, detailed examination geometric structure diamete and operational factor are on the impact of flue gas flow field in spray column, numerical simulation result shows, in spray column, flue gas flow field general trend is consistent substantially, and geometric structure diamete and operational factor have considerable influence to flue gas flow field in tower.Tsing-Hua University Zhao Zhe with 300MW unit wet process of FGD spray column for research object, Fluid Mechanics Computation common software is utilized to simulate its inside Two-Phase Flow Field, when not spraying, observe after high velocity smoke enters tower body and directly impact the tower wall relative with inlet flue duct, be forced to after being obstructed change direction upwards deviation, successively through 4 spraying layers, arrive outlet, within whole tower body, form an obvious high gas velocity band, its width accounts for 1/3 of tower diameter.In addition, due to the pressure confines of outlet, cause part to arrive the flue gas of outlet along the backflow of right side tower wall, converge with import high velocity smoke through after 4 spraying layers successively downwards, like this, a clockwise large whirlpool is formed in the first half of whole tower.
Rotating stream tray is a kind of jetting type tower plate, have simultaneously dust-removal and desulfurizing, load is high, pressure drop is low, not easily stifled, the feature such as operating flexibility is wide, is widely used in the aspects such as oil, chemical industry, light industry and environmental protection.Air-flow enters below blade, absorbing liquid is evenly distributed to each blade by middle blind plate above column plate, form thin liquid layer, absorbing liquid is sprayed into fine drop by the air-flow rotated upwards, get rid of Xiang Tabi under the influence of centrifugal force and form pendular ring, flow to collecting tank under gravity, and flow to by downspout on the blind plate of lower one deck column plate.
What think of journey of Changzhou University etc. are to the speed of gas phase flow field in rotating stream tray scrubber and the numerical simulation of pressure drop, point out that in tower, flue gas axis and radial velocity are to the material impact of Heat and mass transfer, and water conservancy diversion template fiberglass desulfurization cigarette tower have axis similar in same rotating stream tray scrubber and radial velocity of flue gas.
Spraying layer part, high-order spraying layer liquid supply pressure deficiency causes the problems such as alkali lye fully can not react with sulfur-containing smoke gas, drop atomizing effect difference, current head it off is all install solution feed pump additional, adopts meshy arrangement piping mode, higher concerning cost mini-plant; And line clogging, not easily changes pipeline.The shortcoming main manifestations of prior art is following several aspect:
1) current " nicotinic acids " type desulfuration chimney, flue gas directly impacts the tower wall relative with inlet flue duct after entering tower body, be forced to after being obstructed change direction upwards deviation, within whole tower body, flue gas deflects, form an obvious high gas velocity band, the high speed band of gas reduces the uniformity of flue gas flow field, thus reduce time of contact and the contact area of flue gas and spray liquid, the present invention passes through the deflector of appropriate design some and version, improve flue gas flow field uniformity in tower, avoid high gas velocity zoning, extend the time of contact of flue gas and drop simultaneously, add the contact area of flue gas and spray liquid,
2) for " nicotinic acids " type desulfuration chimney, the condensation water recovery system that the people such as Wei Yu propose, need at tower wall processing hole, technique is loaded down with trivial details, reduce chimney intensity, if hole fouling, blocking, chimney height is large, difficulty is brought to cleaning work, need in addition to install swirl-flow devices additional, complex structure, for this type of shortcoming, adopt deflector drainage alternative swirl-flow devices on the one hand, the high efficiency demister of technical maturity can be directly adopted to replace condensate water recovery device at steady flow segment on the other hand, simultaneously due to wet flue gas spiral, the drop that the centrifugal force that radial velocity produces makes quality large is rebuffed and is dropped down onto waste liquid pool, reduce the water content of wet flue gas,
3) desulphurization system fouling is many at parts surfaces such as inner wall of tower, nozzle, jet pipes, and discontinuous deflector adopts and is interrupted, and height is arranged, reduces hydrops fouling.Absorption tower radial temperature is that center is higher, the distribution mode that side surface side is on the low side, and like this, the solid particulate matter carried in flue gas easily collides the wall investing absorption tower, and scale formation occurs.The deflector that the present invention proposes makes the movement effects on flue gas generation screw, flue gas radial velocity contributes to the high-temperature flue gas of center and the low-temperature flue gas contact heat transfer of surrounding, make flue-gas temperature in tower even, effectively reduce by the too low scale problems caused of temperature.In addition, because the flue gas of radial motion has the effect of washing away to tower wall, jet pipe etc., this contributes to the dirty layer on cleaning member surface;
4) spray column generally adopted at present, flue gas is rebuffed after break-in and is moved upward, spiral effect is weak, and the water conservancy diversion template desulfurization cigarette tower that the present invention proposes, flue gas spiral effect is strong, there is the effect of dust-removal and desulfurizing simultaneously, realize the object of two-stage dust removal, can reduce even without the need to investment and the operating cost of dust arrester; In addition, what think of journey of Changzhou University etc. are to the speed of gas phase flow field in rotating stream tray scrubber and the numerical simulation of pressure drop, point out the speed that flue gas tangential velocity in tower reflects fluid and rotates in rotating stream tray scrubber, embody the size of centrifugal force, be also that can gas-liquid mass transfer absorb the key factor fully carried out simultaneously.Tang of Southeast China University to always cherish the memory of etc. and points out after carrying out Three-dimensional simulation to the flow field of spray column void tower, rotates the flue gas risen, and turbulent extent is very large, and being conducive to gas-liquid well mixes, and can improve desulfuration efficiency.Water conservancy diversion template fiberglass desulfurization cigarette tower also has spiralling air-flow similar in same rotating stream tray scrubber, therefore shows above-mentioned various advantages.
5) Zhejiang University woods Yongming is by finding the numerical simulation of wet sprinkling tower, flow field between flue gas demister and most top layer spraying layer is existed to become from absence of vortices has 2 vortexs to occur, and flue gas is adherent more serious, blocking and the fouling of demister may be caused herein, the spiral flue gas that the present invention produces because of deflector, not only have rectified action to flue gas, go back uniform crosssection direction flue gas pressures, this contributes to demister dewatering work;
6) in Multi-layer sprinkling desulfurizer, spray liquid is by needing during jet expansion to keep certain spray pressure, because spraying layer sectional area is comparatively large, need to ensure that its pressure is more than certain numerical value, normally realize supervisor's each several part force value by the method changing caliber impartial.And the employing of caliber junction is existing reduced pipe on market, also known as concentric reducer, reducing coupling.This is one of chemical industry pipe fitting, for two kinds of different tube diameters pipeline between connection.For small-sized desulfurizer, adopt meshy arrangement, cost compare is high, needs configuration solution feed pump quantity also many.
Existing traitorous device, generally only have 3 logical or 4 to lead to, the number of tubes namely same aspect connected is limited, in small-sized desulphurization system, need to keep isobaric evenly spray more difficult, also need more main pipeline to support, layout is comparatively complicated, install and change single pipe all inconvenient.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, propose a kind of Industrial Boiler water conservancy diversion template fiberglass desulfurization cigarette tower, the multitube of described desulfurization cigarette tower device of switching political loyalty is put at small-sized desulfurizer lining in conjunction with deflector, can evenly spray desulfurization alkali lye, spray liquid is fully combined with flue gas, and there is larger coverage rate, the use of solution feed pump can be saved simultaneously, simplify pipeline arrangement.
