An online automatic blockage removal device and a wet electrostatic precipitator

Abstract

The invention relates to an on-line automatic unclogging device. The on-line automatic unclogging device comprises a sprayer; a nozzle is arranged on the sprayer; the on-line automatic unclogging device further comprises a leakage storage unit and a reset component which enables the leakage storage unit to move relative to the sprayer; the leakage storage unit comprises water storage cavities and an ejection pin matched with the nozzle; the water storage cavities collect water from the sprayer and are internally provided with water outlets enabling water to flow out; when the nozzle of the sprayer is clogged, the water inflow in the water storage cavities is smaller than the water outflow from the water outlets, so that the leakage storage unit approaches to the sprayer under the action of the reset component; and dirt in the nozzle is removed by the ejection pin. The invention further discloses a wet electric dust collector. By adopting the scheme disclosed by the invention, dirt on the nozzle can be automatically removed; unclogging is realized; the labor cost is reduced; and the production efficiency is improved.

Description

technical field [0001] The invention relates to a dust collector, in particular to an online automatic block removal device and a wet electric dust collector. Background technique [0002] Dust removal equipment is relatively common both in our life and in industrial production. For example, a vacuum cleaner is a common electrical appliance in our life; in industrial production, the commonly used wet electrostatic precipitator uses liquid to flush the surface of the dust collector to clean the dust, which can effectively collect fine particles (PM2.5 dust, SO 3 acid mist, aerosol), heavy metals (Hg, As, Se, Pb, Cr), organic pollutants (polycyclic aromatic hydrocarbons, dioxins), etc. After using the wet electrostatic precipitator, the dust emission in the wet flue gas can reach 10mg / m 3 Even 5mg / m 3 Below, the dust collection performance has nothing to do with the dust characteristics, and is suitable for the treatment of wet flue gas, especially for the treatment of dust...

AI Technical Summary

Problems solved by technology

[0004] Since the gas to be dedusted is full of dust, sulfide or heavy metals, the spray nozzle is easily blocked by the above dirt, so that it cannot be sprayed well, and the dust removal effect is poor; in a large wet electrostatic precipitator system, The operator needs to shut down the boiler and manually clear the blockage, which is troublesome and affects production
