Description

The energy-efficient solidifying formula electric-bag complex dust collector of vortex flow spray

Technical field

It the utility model is related to deduster technical field, and in particular to a kind of energy-efficient vortex flow for high pollution industry The solidifying formula electric-bag complex dust collector of spray.

Background technology

Deduster or cleaner, it is the equipment that dust is separated from flue gas.Its performance is with accessible Gas flow, gas are expressed by drag losses during deduster and efficiency of dust collection.Meanwhile price, operation and the dimension of deduster The difficulty or ease of shield expense, service life length and operational administrative are also an important factor for considering its performance.Deduster is boiler and work The facility commonly used in industry production.In particular for handling the deduster of the Industrial Boiler of high pollution or industrial furnace, removed from ventilation From the point of view of dirt, dust is also referred to as solid granule, particularly harmful dust, when their long-time floating states are present When in air, dispersion, also referred to as aerosol is presented, wherein air is decentralized medium, and solid particle is dispersed phase.Dedusting Device is exactly the equipment that this solid granule is separated from aerosol.According to the principle of effect, deduster can be divided into dry Formula mechanical dust collector, wet scrubber, gravel bed filter, sack cleaner and electric cleaner etc..
