Circulating cyclone electrocoagulation environmental-protection device and method for industrial dust removal

Abstract

The invention discloses a circulating cyclone electrocoagulation environmental-protection device and method for industrial dust removal. The device is composed of a power air supply system, a cyclonecharged device, a spider-web reinforcement charged device, a coagulation dust collection device, a dust collection device and a pure-gas outlet pipe network which are connected in sequence; dust blocking sheets are installed at a dust-containing gas inlet and the outlet pipe network and are mainly used for preventing foreign matters from entering a dust remover; and a dust blocking plate at the outlet of a collector prevents residual large-particle dust from polluting clean air, and every two layers of burr electrodes in a cyclone are staggered in a 45-degree manner. On the one hand, the confusion degree of a flow field is increased, and the probability of dust collision is increased; on the other hand, the anti-corona phenomenon is inhibited to a greater extent, and the situation that local overhigh field strength is caused due to too-close distance of electrode rods is prevented; a dust collecting chamber further coagulates the charged dust, and the dust becomes large particles whichare easy to clean; and in order to prevent the high-concentration dust from suppressing the corona phenomenon, clean air can be mixed through a check valve, and the dust removal efficiency is improved.

Description

technical field [0001] The patent of the invention relates to the field of industrial dust removal and environmental protection, in particular to a recyclable cyclone electrocoagulation and industrial dust removal environmental protection device and method, which are used in technical fields such as industrial fine dust removal and flue gas treatment. Background technique [0002] Electrostatic dust removal is a dust removal technology widely used in industrial production and environmental governance, but it is difficult to remove particles below 10 μm. In the 1990s, the emergence of a three-zone electrostatic precipitator that charges dust in an alternating electric field of the same polarity has attracted widespread attention in dust removal research. Electrocoagulation and dust removal can reduce the emission of particles smaller than 2.5 μm by 70%, and reduce the emission of particles between 0.1 and 1 μm by 15%. The collection rate of dust removal quality achieved by t...
