Fig. 2 is the plan structure schematic diagram of trellis component.
Fig. 3 is the A-A sectional view of Fig. 2.
In figure, 1 trellis component, 1-1 riser, the oblique plate of 1-2,2 support beam, and 3 arcs connect liquid bath, 4 discharging tubes, 5 wet electrical dust precipitators, 6 electrode assemblies, 7 ash buckets.
Detailed description of the invention
Structure and the operation principle of the airflow uniform distribution device of wet electrical dust precipitator anti-droplet entrainment are further illustrated below.
As shown in Figure 1, wet electrical dust precipitator 5 is provided with gas approach, outlet and electrode assemblie 6, the airflow uniform distribution device being connected with anti-droplet entrainment of electrode assemblie 6, it is located in supporting the trellis component 1 on beam 2, supports beam 2 and is fixed on the inwall of wet electrical dust precipitator 5. The bottom of wet electrical dust precipitator 5 is provided with ash bucket 7, and wet electrical dust precipitator bottom surface tilts to ash bucket 7 direction.
The planar structure of trellis component 1 such as Fig. 2: multiple riser 1-1 of parallel longitudinal arrangement are connected staggered with the multiple oblique plate 1-2 of horizontally-parallel arrangement formed trellis component, wherein, each parallel oblique plate 1-2 tilts (Fig. 3) with the angular same direction of same inclination, and each oblique plate 1-2 is equipped with upper and lower two arcs and connects liquid bath 3, each arc connects liquid bath 3 and extends through from each parallel riser 1-1, and end notch leads to the bottom surface of wet electrical dust precipitator 5 by discharging tube 4.
Fig. 3 is the A-A sectional view of Fig. 2, and Fig. 2 is visible in conjunction with Fig. 3, and each riser 1-1 is perpendicular to horizontal plane, and each oblique plate 1-2 is perpendicular to riser 1-1, but horizontal by an inclination angle, the trellis component 1 being consequently formed.
In conjunction with Fig. 1, Fig. 2, Fig. 3 it can be seen that enter the flue gas (dust-laden is containing mist) of wet electrical dust precipitator 5 when electrode assemblie 6, the dirt contained in flue gas and fog are by electrostatic adsorption and be gathered into dust-laden drop. Being stripped of the flue gas uniform effect by trellis component 1 of cloud, steady air current ground continues flowing, finally discharges from exhanst gas outlet. Simultaneously, above-mentioned by static focus dust-laden drop because of on action of gravity drops to oblique plate 1-2 then landing enter arc and connect liquid bath 3, the drop assembled in groove flow to the notch direction of low level, is flowed out by discharging tube 4, after in the bottom surface of wet electrical dust precipitator 5 inflow ash bucket 7, be collected separation. Supporting the trellis component 1 placed on beam 2 to be made up of multistage, such as Fig. 1, support and be placed with four sections of oblique plate 1-2 from left to right on beam 2, the incline direction of the oblique plate 1-2 in adjacent each section is reverse mutually. The airflow uniform distribution device of this anti-droplet entrainment adopts corrosion resistant FRPP material (composite material of polypropylene and glass wool cloth) to make.
To sum up, this device efficiently solves wet electrical dust precipitator dust-laden drop and is easily carried secretly by exiting flue gas and the problem that causes fume emission to exceed standard, it is ensured that purifying smoke qualified discharge.
