Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] Such as figure 1 , figure 2 , image 3 with Figure 4 As shown, the stainless steel polishing dust enters the dust adsorption box 7 through the air inlet 5, and the dust adsorption box 7 is equipped with a high-speed powerful exhaust fan 1, so that the box body is in a deep negative pressure state; The output line of the generator 6 leads to the five-layer dense barbed wire 2 arranged vertically in the adsorption box. The barbed wire 2 blocks the dust entering the dust adsorption box with the dual functions of dense grid blocking and electrostatic adsorption; A water pipe 3 is provided in front of the barbed wire 2 to form a water curtain, which can block the dust and wash down the accumulated dust on the barbed wire 2, and finally form a slurry and flow into the funnel 4 below the dust adsorption box 7 and then inject it into the collection bag; The dust i...

Abstract

The invention discloses a method for treating stainless steel polishing dust. In the method, process flows such as adsorption, collection, filtration, fractionation and recovery of heavy metals from dust are performed on polishing dust produced during the production of stainless steel wares by using equipment such as a dust adsorption box, a filter tank and a fractionating tower, so that the aims of preventing environmental pollution caused by the stainless steel polishing dust and recycling the heavy metals in the dust can be fulfilled.

Description

technical field [0001] The invention relates to a treatment method for stainless steel polishing dust, in particular to a method for collecting stainless steel polishing dust and recovering heavy metals in the dust. Background technique [0002] Polishing is an indispensable process in the production of stainless steel utensils. During polishing, a large amount of dust containing polishing abrasives and stainless steel dander will inevitably be generated. Polishing abrasives are rich in chromium oxide particles, and stainless steel shavings are rich in heavy metals such as nickel, molybdenum, and titanium. These polishing dusts enter the air, water, and soil, causing serious pollution to the surrounding environment, and enter the human body through various channels, seriously damaging human health. At present, although some domestic manufacturers have adopted methods such as equipping operators with dust masks, installing powerful exhaust systems, collecting dust with cloth...
