The specific embodiment
A kind of coal-burning boiler exhaust gas desulfurization cleaner, it contains: horizontal tower 1; Is furnished with atomizer 7 in the described horizontal tower 1; In the described horizontal tower 1, be furnished with catching sheet A2 near its smoke inlet place, exhanst gas outlet is furnished with catching sheet B3 near 13 places; Between described catching sheet A2 and catching sheet B3, is furnished with screen pack 4; On described catching sheet A2, catching sheet B3 and screen pack 4, be provided with water distributor 5.Described catching sheet A2 and catching sheet B3 are that bilayer stacks the formula arc plate structure; Described screen pack 4 is the scale net.The utility model also is furnished with vertical tower 6; Described vertical tower 6 middle parts are Venturi tube 9; In described vertical tower 6, be provided with atomizer 8; The smoke inlet sealing-in of the exhanst gas outlet of described vertical tower 6 and horizontal tower 1.In addition, the utility model also is furnished with dehydrating demisting device 10; Exhanst gas outlet 13 sealing-ins of the air intake of described dehydrating demisting device 10 and horizontal tower 1; In the described dehydrating demisting device 10, near its air intake, contain spinning disk 11, near its gas outlet, be furnished with scale net 12.
The desulfurization and dedusting tower is a main equipment of the present utility model, and its structure can adopt the upright combined type that crouches, and tower inner core part has atomizer, Venturi tube, double-deck arc, scale net, water distributor.
Operation principle: (180 ℃ ~ 200 ℃) flue gas that the coal-burning boiler outlet is discharged, enter tower top by vertical tower butt tube with V1=13m/s speed with the desulfurization and dedusting tower, atomizer is with Pg=3～6kg/cm
2Pressure sprays evenly alkalescence (pH value is more than 8) fine water droplets and makes the flue gas state that reaches capacity.
Saturated flue gas enters Venturi tube and speed-raising gradually with V2=18m/s speed, and by trunnion, speed increases pressure and descends with V3=26m/s speed, and owing to adiabatic expansion causes the condensing of water vapour, the flue gas particle adheres on the liquid film.Slow down gradually by the flue gas behind the trunnion, speed reduces pressure and rises, discharge with V4=18m/s speed when flue gas passes through Venturi tube end flared part, the water droplet that flue gas will swim collides coalescence mutually and becomes bigger water droplet and carry smoke particle, discharges from Venturi tube.Thick smoke particle is separated from flue gas around the atomizer of vertical tower bottom, drains with current.
Flue gas enters horizontal tower with V5=16m/s speed by vertical tower upper outlet.It is V6=9m/s that flue gas is gone into tower speed, and expansion and atomizing spray carry out synchronously, makes the particle encounter coalescence, reaches the purpose of particle humidification, increase, weightening finish, for double-deck arc interception provides condition.
Flue gas stacks formula arc core members (cross section ladder layout) with V6=9m/s speed bump bilayer, and the arc face is covered with moisture film.The main effect of preceding laminate is: evenly divide gas and speed-raising and particle to increase weightening finish; Laminate bump back laminate before flue gas passes with V7=18m/s speed.The main effect of back laminate is the above particle of interception PM10.The particle of the inertial collision coalescence of particle is bonded on the moisture film,, discharges outside the tower with current at the bottom of the tower downstream at the bottom of the landing tower along the arc face.
After flue gas passed arc, with whole current stabilization of V8=2.8m/s speed and atomizing spray, the following particle of interception PM10 provided condition in order to touch net.
Flue gas is touched net with V9=2.8m/s speed, the inertial collision coalescence, and the part particle is along at the bottom of the net landing tower, and the part particle is adsorbed on the steam bubble at scale downwardly facing opening place, along at the bottom of the net landing tower, discharges outside the tower with the current at the bottom of the tower.
Flue gas is worn net and mistake with V10=8.4m/s speed, touches squamous net (aperture opening ratio of net at the corresponding levels is lower than preceding road net) again, almost particles all in the flue gas is tackled.
Flue gas fully and moisture film and bubble affinity interaction, and is accepted spray in horizontal tower, alkaline water (more than the PH8) is almost the sulfur dioxide in the flue gas, nitrogen oxide, chloride like this, be reacted into diluted acid with tower at the bottom of outside the water discharge tower.
Dehydrating demisting device, outward appearance are cross garden post solid.Its core members is made up of eddy flow plate and zigzag squamous net.
Dehydrating demisting device operation principle: the band shredded tobacco for water pipes gas after the purification, through the terminal booklet plate 14 that is provided with of horizontal tower, after dividing gas (preventing the bias current of upper outlet flue gas) and retaining to fall bigger water droplet, produce rotation and centrifugal motion when entering the eddy flow plate by blade 11 with V11=28m/s speed by the bottom of dehydrating demisting device, drop (majority is 50 ~ 500 μ m) and mist collide revolving of separating in the coalescence Cheng Kecong flue gas mutually and drip, the gravitate afflux is to collecting tank, and discharges outside the tower at the bottom of flowing to tower by downspout again.
Do not purify the flue gas of water smoke as yet, wear net with V12=9m/s speed net-fault 12 and V13=18m/s speed respectively; Wear net with V14=18m/s speed net-fault 12 and V15=36m/s speed; Wear net 12 with V16=36m/s speed net-fault 12 and V17=72m/s speed.Along with increasing progressively of speed, the inertial collision active force is increasing, and the coalescence of drop and mist is more and more stronger, almost all reaches the purpose of dehydration and demist.
Buck from the desulfurization and dedusting tower is discharged enters compound belt press filtration sieve by the bucket type mouth, and the ash that is pressed into is also packed by sack filling machine; The water that squeezes out is input in the lime agitator tank and stirs milk of lime, and when the pH value of milk of lime＞8, milk of lime input horizontal screw centrifuge, isolated alkaline water uses for the desulfurization and dedusting tower; Solid particulate matter is packed by packing machine.
Under cold conditions, start the water pump of alkaline water, supply with and be arranged in some water pots of arranging on the desulfurization and dedusting tower, after water pot is full of, starts some the water pumps of supplying with water distributors, after atomizer, arc, the strong screen cloth water of squama are normal, the startup boiler operatiopn.As shown in Figure 1,15 is water pot.16 for detecting the hole.17 for manhole and.After detecting the normal operation of hole boiler, start compound belt press filtration sieve in succession, sack filling machine, horizontal screw centrifuge, the milk of lime agitator tank is opened the water tank valve, and alkaline water is input to the desulfurization and dedusting tower by feed pump and uses.
The core data of operation is the alkaline water that guarantees pH value＞8; The key data of monitoring is: flow in processing procedure of the every legal index of smoke inlet and outlet, flue gas, pressure, temperature etc.
Horizontal tower of the present utility model can dock with dry dust removal equipment, forms the semi-dry desulfurization high-efficiency desulfurization and removes the following pellet of PM10.
