Wet-type electric dust-remover

Abstract

The invention provides a wet-type electric dust-remover. An insulation box (7) is installed on the top end of the upper external of a cylinder body (1) of the wet-type electric dust-remover; a negative pole holder (3) is installed on the external middle position of the cylinder body (1) of the wet-type electric dust-remover; a top washing system (14), an upper hanging bracket (6), a wire electrode(5), a precipitation electrode (4), a hanging bracket pull rod (15), a lower hanging bracket (2) and a preprocessing system (13) are installed in the cylinder body (1) of the wet-type electric dust-remover from top to bottom; the precipitation electrode (4) is formed by a plurality of orthohexagonal honeycomb holes; the inscribed circle each honeycomb hole is 360mm; a wire electrode (5) is installed on the center of each honeycomb hole, and the deviation is not greater than 5mm; and, the upper hanging bracket (6) and the lower hanging bracket (2) are connected and tensioned by the hanging bracket pull rod (15). The dust-remover provided by the invention is long in service life and good in stability during the period of running; the precleaning system directly purifies the large particlesmixed in the gas and coagulates the small fog drips into large particles, so that the static system absorbs and drops down the impurities directly and effectively; and thus, the preprocessing is achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and relates to a wet electrostatic precipitator, which is widely used in various industries such as steel and coal chemical industry. Background technique [0002] Under increasingly stringent environmental protection policies, traditional high-energy-consuming and high-pollution industries such as iron and steel and coal chemical industry urgently need a high-efficiency dust collector to achieve ultra-low emissions. Traditional wet electrostatic precipitators are widely used in iron and steel, coal chemical industry and other fields, and can achieve a particle emission concentration of less than 50mg / Nm 3 , but can not achieve less than 10mg / Nm 3 Ultra-low emission requirements. [0003] Wet electrostatic precipitator adopts three structural forms: concentric circle type, tubular type and honeycomb type. Regardless of the structure, its working principle is to apply a high-vol...

AI Technical Summary

Problems solved by technology

[0005] The electrode wire of traditional wet electrostatic precipitator is usually Made of stainless steel light wire, the electrode wire is tightened by a heavy hammer, which reduces the working efficiency and stability of the equipment, and even spark discharge occurs; furthermore, common faults such as corona wire disconnection often occur in wet electrostatic precipitators

[0006] In recent years, as environmental protection requirements have become more and more stringent, achieving ultra-low emissions has become a future trend, and the requirements for purification efficiency of wet electrostatic precipitators have increased. Traditional wet electrostatic precipitators cannot meet the needs of related industrial upgrading.
