Technical Field

The utility model belongs to the technical field of the flue gas dust removal, concretely relates to receive dirt device in advance for dust remover import position.

Background

The electric dust collector builds an electric field through the cathode wires and the anode plates which are arranged in a staggered way, so that fine dust is electrified and is adsorbed on the anode plates for dust removal, the air flow inlet of the common electric dust collector is directly exhausted by the draught fan, and the cathode wires and the anode plates build the electric field and are difficult to uniformly remove dust on the flow cross section of the whole air flow, so that the air flow still contains a lot of dust, which causes that the whole dust removal efficiency is difficult to improve, aiming at the phenomenon, the patent application number is CN201520813559.6, the patent name is a novel high-concentration electrostatic dust collector pre-dust collecting device utility model, which comprises a diversion trench, a large particle dust channel and a medium particle dust channel, wherein the diversion trench is arranged below the feed inlet of the high-concentration electrostatic dust collector, the large particle dust channel and the medium particle dust channel are sequentially arranged in front of the folding plate of the high-concentration electrostatic dust collector to form a pre-dust collecting channel, the rear of the folding plate is provided with an air equalizing plate, the bottom of the pre-dust collection channel is communicated with a dust collection hopper, the diversion trench is communicated with the large particle dust channel, and materials enter the large particle dust channel and the medium particle dust channel from the feed inlet in sequence through the diversion trench to be purified for two layers and then enter the high-pressure part of the high-concentration electrostatic dust collector through the folding plate and the air equalizing plate. The high-concentration dust is collected when not entering the electric field, so that the concentration of the dust entering the dust collecting electric field is reduced to the maximum extent, the dust removal efficiency of the electrostatic dust collector is effectively improved, and the service life of the electrostatic dust collector is effectively prolonged.

However, a right-angle bend exists between the dust inlet channel and the feeding channel of the electrostatic dust collector in the scheme, when air with dust particles enters the electrostatic dust collector, the right-angle bend can generate a resistance effect on the air with the dust particles, the air flow entering the electrostatic dust collector can be obviously reduced, and the electrostatic dust collection amount in unit time is reduced. The uneven distribution of the air can be influenced, the air is gathered at the lower part of the electrostatic dust collector more before entering the electrostatic dust collector, the dust collection work of the electrostatic dust collector is uneven, and the dust collection efficiency is reduced.
