Series filter bag type ultrasonic water mist laminating welding fume purification equipment

Abstract

The invention relates to series filter bag type ultrasonic water mist laminating welding fume purification device, which comprises a shell, a plurality of dust removal and purification assemblies are arranged in the shell, an air inlet is formed in the lower portion of the shell, each dust removal and purification assembly comprises a plurality of cloth bags at the bottom, and an ultrasonic atomizer is arranged on the lower portion of the inner side of the shell; each dust removal and purification assembly comprises a pulse air generator capable of emitting pulse air, a suction fan used for sucking air and a control valve used for controlling the pulse air generator and the suction fan to be alternately connected with the cloth bag. The device effectively solves the problem that when existing negative pressure suction equipment collects and purifies welding fume, finer solid particles such as iron oxide, silicon oxide, copper oxide and manganese oxide smaller than 2.5 micrometers in the welding fume are difficult to collect and purify; and toxic and harmful aerosol particles such as hydrophilic ultrafine nitric oxide, carbon monoxide, sulfur dioxide and the like can be filtered and adsorbed.

Description

technical field [0001] The invention belongs to the field of purification equipment, and in particular relates to a series filter bag type ultrasonic water mist film-coated welding fume purification equipment. Background technique [0002] The electrode consists of a core and a coating. In addition to a large amount of iron, the welding core also contains carbon, manganese, silicon, chromium, nickel, sulfur and phosphorus; the inner material of the coating is mainly composed of marble, fluorite, rutile, pure salt, water glass, ferromanganese, etc. During welding, the arc discharge produces a high temperature of 4000°C-6000°C. While melting the welding rod and weldment, a large amount of smoke and dust are generated. The main components are iron oxide, manganese oxide, silicon dioxide, silicate, etc., and the smoke and dust particles are diffuse. In the working environment, it is easily inhaled into the lungs. Long-term inhalation can cause fibrous lesions in lung tissue, w...
