Technical Field

[0002] Furfural production produces a large amount of furfural residue. After preliminary drying, the residue is then burned in a boiler to generate steam for production. Since the initially dried residue contains approximately 20% moisture, this moisture enters the dust collector and desulfurization system along with the flue gas during combustion. This high moisture content in the flue gas often causes condensation and compaction in the dust collector, impacting dust removal effectiveness. Consequently, the filter plates need to be cleaned frequently, increasing costs and requiring frequent boiler shutdowns for cleaning and maintenance, which wastes time. Summary of the Invention

[0016] The flushing mechanism 7 includes a water pump 9, a water supply pipe 10, and a water spray pipe 11. The water pump 9 is fixed to the back of the outer shell of the dust removal chamber 3. The water spray pipe 11 is fixed to the lower end of the air outlet 6 and the top of the electrostatic adsorption mechanism 8 and is located inside the dust removal chamber 3. The water supply pipe 10 connects the water pump 9 and the water spray pipe 11. The water spray pipe 11 has spray holes distributed around the circumference. The water pump 9 is controlled by an external drive to pump water into the water supply pipe 10, and then sprayed out through the water spray pipe 11. The water mist is evenly sprayed in all directions, covering every position of the electrostatic adsorption mechanism 8, facilitating the flushing of dust and removing it, thereby improving the dust removal effect.

[0017] The electrostatic adsorption mechanism 8 comprises multiple opposing sets of suction electrodes 12 and discharge electrodes 13, each secured to the dust removal chamber 3 via a partition. Multiple sets of suction electrodes 12 and discharge electrodes 13 are arranged side by side and vertically mounted on the partition. Multiple sets of suction electrodes 12 and discharge electrodes 13 form a set, each consisting of one suction electrode 12 and one discharge electrode 13.
