Abstract
The invention discloses a cylindrical vertical wet-type explosion-proof and voltage-resistant electric precipitator. The cylindrical vertical wet-type explosion-proof and voltage-resistant electric precipitator comprises a shell of a cylindrical vertical tower structure. An air inlet is formed in the top of the shell, and an air outlet is formed in the side wall of the lower portion of the shell. The middle of the air inlet is connected with an airflow uniform distribution device. Plate-shaped dust collection electrodes are connected in the shell and grounded together with the shell. The plate-shaped dust collection electrodes and frame-shaped discharge electrodes are vertically arranged in parallel at intervals. Four hanging heat preservation boxes are arranged on the upper portion of the air inlet. The frame-shaped discharge electrodes are connected with a high-voltage power supply through the hanging heat preservation boxes. A high-voltage electrostatic field is formed between the plate-shaped dust collection electrodes and the frame-shaped discharge electrodes. Nitrogen displacement system inlets are formed in the hanging heat preservation boxes and the bottom of the shell. Spraying nozzles are arranged above the plate-shaped dust collection electrodes and the frame-shaped discharge electrodes. A dust removal wastewater outlet formed in the bottom of the shell is communicated with a settling pond. The explosion-proof and voltage-resistant cylindrical vertical structure is adopted for the shell, and an explosion-proof electrode matching structural form is adopted for the plate-shaped dust collection electrodes and the frame-shaped discharge electrodes. The cylindrical vertical wet-type explosion-proof and voltage-resistant electric precipitator integrates the dust-removing, explosion-proofing and voltage-resisting effects.
