Wrong arranged, realization are completely covered, but do not influence the flowing of flue gas.
5. a kind of full-automatic three-level desulfation dust-extraction device according to claim 4, it is characterised in that: lower two layers flue dust is received
Collect and set in each fFlue gas collector of structure there are two Water membrane nozzle (8), which is installed on the cigarette of fFlue gas collector
The top of gas trapezoidal plate (6), and it is provided on the inside of flue gas trapezoidal plate (6) narrow slit (18) of 0.1mm；Each Water membrane nozzle (8)
There are the narrow slit of 0.1mm (18) between flue gas trapezoidal plate, and the medicament that Water membrane nozzle (8) sprays can be from the narrow slit (18) of 0.1mm
Outflow, and water membrane is formed on the surface of flue gas trapezoidal plate (6), it further adsorbs flue dust in flue gas while and preventing flue gas from receiving
Dust stratification on storage.
6. a kind of full-automatic three-level desulfation dust-extraction device according to claim 1, it is characterised in that: the fFlue gas collector
Each flue gas trapezoidal plate (6) and half-open U-shaped ash removal pipe (7) between have a fan-shaped gap (17), be easier flue gas
It is collected, while reducing the flow resistance of flue gas；And it is main except grey-way (9) are the tubular structures of upper end sealing, from flue gas
Import is led in the pond of lower end, and lower end pond is connect with dedusting sewage draining exit (10).
