Problems solved by technology
After testing and calculation, this part of side channeling air will affect the emission efficiency of the dust collector by about 0.03-0.05%.
[0004] With the promulgation of new air pollutant emission standards, the emission concentration of the dust collector must be controlled at 50mg / Nm 3 Below, or even lower, the existing technical equipment has been unable to meet this requirement

Embodiment Construction
[0014] The present invention will be described in further detail below with reference to the drawings and specific embodiments.
[0015] This specific embodiment includes a cathode wire frame 3, a cathode wire 4, a supporting steel plate 5, a grooved plate 8, a sprocket 10, a transmission shaft 11, a transmission chain 12, a connecting rod 13, a wire brush 14, and a reduction motor 15. The cathode wire frame 3 made of channel steel is welded to the upper and lower ends of the vertical beam 2 of the end electric field cathode system. At the position corresponding to the channel plate 8, the cathode wires 4 are connected one by one through the hooks provided with the cathode wires 4 4 Hang on the lifting ring welded to the upper and lower frame 3 on the cathode wire. Four supporting steel plates 5 are respectively welded in parallel and equidistant to the upper end seal 6 and lower end seal 9 of the outlet of the electrostatic precipitator. A drive shaft 11 passes through the two s...

The invention provides a brushing type groove-shaped plate dust repurifying device for an electric dust collector, which comprises a cathode line, a cathode line upper frame, a cathode line lower frame, a support steel plate, a chain wheel, a drive shaft, a drive chain, a connecting rod, a steel brush, a groove-shaped plate and a speed reducing motor, wherein the cathode line upper frame and the cathode line lower frame are welded at the upper end and the lower end of a vertical beam of a tail electric field cathode system, and the cathode line is hung on suspending rings welded on the cathode line upper frame and the cathode line lower frame. The fine dust is again electrically adsorbed on the groove-shaped plate to be collected by a high-pressure electric field formed between the cathode line and the groove-shaped plate. When the dust on the outlet groove-shaped plate is accumulated to a certain thickness, the speed reducing motor is started, the drive shaft connected with the speedreducing motor drives the chain wheel to rotate, and the drive chain and the connecting rod and the steel brush which are welded on the drive chain move along with the chain wheel to brush the dust on the groove-shaped plate. The invention has simple and reasonable structure without increasing the volume of the electric dust collector and can effectively improve the dust collecting efficiency of the electric dust collector.
Description
Technical field [0001] The invention relates to an electric precipitator, in particular to a brushable trough plate dust repurification device for the electric precipitator. Background technique [0002] At present, the first electric field of general electrostatic precipitators can capture 80% to 90% of the dust content of the gas, and they are all particles with a relatively coarse particle size. The dust captured by the subsequent electric field is getting finer and finer, and the last electric field captures The dust is fine dust. Some finely charged dust particles are carried out of the electric field into the atmosphere by the airflow before they reach the surface of the dust collecting plate, and the secondary dust particles generated when the final electric field is vibrated to clean dust also directly enter the atmosphere. [0003] In order to collect these escaping fine dust particles, some manufacturers of electrostatic precipitators generally design a trough-shaped pla...
