Abstract

The invention relates to a pre-charging electrocoagulation bag type dust remover. A dual- pole charging device is arranged in an air inlet flue (11) and comprises a group of earth poles (7) arranged at intervals and positive and negative discharging poles (8), so that dual-pole charging regions (13) with positive and negative alternate electric fields are formed. A mixed coagulation region (22) is arranged in the tail space of the air inlet flue (11) and the buffering space of a filtering cabin, so that the coagulation efficacy of PM2.5 subparticles is observably improved. Coagulated large particles rapidly enter a filter bag filtering cabin (12) along with air currents, so that dust-air separation is performed by the filter bag. The dust remover disclosed by the invention utilizes a dual-pole charging electrocoagulation mechanism, and oversized PM2.5 subparticles are regularly arrayed on the surface of the filter bag and loosely stacked, so that the oversized PM2.5 subparticles are very liable to trap and remove. The dust remover has the significant characteristics of good coagulation effect on the subparticles, high trapping efficiency on the PM2.5 and the like, and is particularly suitable for reforming and improving a bag type dust remover adopting a traditional structure. The dust remover is economical, practical, convenient and high-efficiency.

Description

technical field [0001] The invention relates to a composite bag-type dust collector, in particular to a pre-charged electrocoagulation combined bag-type dust collector specially designed for efficient collection of PM2.5 fine particles in the field of ventilation and dust removal. technical background [0002] The dust removal efficiency of the electrostatic precipitator can reach more than 99.9%, but its efficiency is usually affected by the specific resistance, concentration, particle size distribution, temperature, humidity, dust removal effect and corrosion of the dust during actual operation, and the dust removal efficiency will drop significantly . The actual operating efficiency is mostly between 98% and 99.8%. Experimental studies have shown that the efficiency of conventional dry electrostatic precipitators in service for PM2.5 fine particles is low. [0003] Compared with the electrostatic precipitator, the bag filter has advantages in capturing ultra-fine dust. ...
