This apparatus structure simplicity of design, investment cost is low, and result of use is obvious, stable.Therefore, the normal operation of steam generator system should be met, again consider investment little, operating cost is low (with numerous employing electrostatic precipitator technique phase specific investment and running cost negligible), also will solve SO2, NOX, micronic dust, ammonia and aerocolloidal qualified discharge becomes this field technical issues that need to address.
Accompanying drawing explanation
It is structural representation of the present utility model shown in Fig. 1;
Figure 2 shows that the structural representation of the utility model moisture film storehouse base plate.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As Fig. 1, 2 are depicted as a specific embodiment of the present utility model, a kind of escape ammonia and aerocolloidal blocking apparatus, be arranged on the top of flue gas desulfurization and dedusting spray tower, include moisture film storehouse, moisture film storehouse is made up of 2205 corrosion resistant plates or glass epoxy, moisture film storehouse base plate 1 is provided with bottom described moisture film storehouse, the top of described moisture film storehouse base plate 1 is provided with recirculated water pipe network 2, described recirculated water pipe network 2 connects circulating pump, described blocking apparatus also includes clean water overflow pipe 3, described clean water overflow pipe 3 bottom connects slurry pool, top is through moisture film storehouse base plate 1, described blocking apparatus also includes dirt mud and unloads stream pipe 4, described dirt mud unloads stream pipe 4 bottom and connects slurry pool, top is through moisture film storehouse base plate 1, base plate 1 top, described moisture film storehouse is provided with liquid level gauge, PH counts, described dirt mud unloads stream pipe 4 bottom and is provided with electrically operated valve, described liquid level gauge, PH counts, electrically operated valve, the switch of recirculated water pipe network 2 connects master control system,
Described moisture film storehouse base plate 1 is provided with and wears pore 5, pore 5 diameter of wearing on described moisture film storehouse base plate 1 is 4mm-8mm, wearing pore 5 spacing is 100mm-140mm, wearing 5 one-tenth, pore equilateral triangle is evenly distributed on moisture film storehouse base plate 1, percent opening is 20%-25% of moisture film storehouse base plate 1, base plate 1 bottom, described moisture film storehouse is provided with rising flue gas dispersion pipe 6, and flue gas dispersion pipe 6 is set to caliber from bottom to top and increases gradually, and flue gas dispersion pipe 6 bottom in described outer circumference is provided with control valve 7.
Moisture film storehouse is arranged on uptake flue outlet top, and flue gas passes through the dispersion pipe of bottom, moisture film storehouse, to guarantee at the uniform velocity through moisture film storehouse base plate.When pretreated neat stress by setting flow velocity by moisture film storehouse base plate wear pore time, bubble is formed at eyelet place, unconnected bubble is by after supernatant layer one by one, the bubble layer of one deck 300mm left and right thickness can be formed at moisture film storehouse substrate, bubbling area, mainly liquid below bubble layer; The middle Bubble Region for motion, being linked together by moving bubble one by one forms; Top is Bao Mo district, and liquid becomes foam at this due to explosion, and large drop falls, and after droplet is brought to demister by air-flow, the overwhelming majority is separated, the neat stress after separation by smoke stack emission in air.Because bubble can provide huge gas-liquid contact surface, and these surfaces merge at bubble, increase, break, constantly update in the violent process that formed again, adhere to greatest extent on liquid film and bubble surface for making the dust particale carried secretly in flue gas and provide sufficient condition, thus reach the effect of dust particale in washing, filtration, separating flue.
According to flue gas resistance size and SO2, the thickness of NOX, flue dust ammonia and aerocolloidal removal efficiency setting water film, the water level value in moisture film storehouse is measured by liquid level gauge, and transmit it to master control system, display is to master-control room interface, and implement adjustment by master control system, when liquid level is lower than initial set value, start the switch of recirculated water pipe network 2, carry out moisturizing, when the numerical value that liquid level gauge is measured reaches moisturizing to setting value, close the switch of recirculated water pipe network 2, unnecessary water can flow into slurry pool by clean water overflow pipe 3; When the solution pH value in moisture film storehouse exceeds setting range value, master-control room interface is fed back to by PH meter (the automatic measurer of PH), and adjusted by master control system, master control system opens electrically operated valve, water in moisture film storehouse unloads stream pipe 4 from dirt mud and flows into slurry pool, then electrically operated valve is closed, start the switch of recirculated water pipe network 2 simultaneously, recirculated water pipe network 2 injects new clear water in moisture film storehouse, to prevent the alluvial of water film storehouse base plate dirt mud, escape ammonia and aerocolloidal absorptivity can be improved with stylish clear water.
This blocking apparatus is as last one SO2 in a kind of process of desulfurization for boiler flue gas denitration dust collecting (removing PM2.5) Trinity process system, NOX, flue dust, ammonia and aerocolloidal intercept process device, final realization is discharged into the SO2 concentration in air :≤30mg/m3, NOX concentration :≤100 mg/m3, dust content is within 20mg/m3, and ammonia and aerocolloidal discharge capacity: 75Kg/h meet the discharge standard required by national environmental protection department completely.
