Description
Technical field
The utility model is related to the exhausting-dusting field in factory building or workshop, more particularly to a kind of ventilation of welding shop
System.
Background technology
In welding process, the heat that electric arc is produced is acted on the molten drop of electrode tip, is at superheat state, temperature
Up to 4,000 to 5,000 degree, metal and its compound are drastically evaporated after high-temperature steam blows out by arc region, rapid to be oxidized and condense
For tiny solid particles, weld fumes is formd, the particle diameter of weld fumes is smaller, average grain diameter is 1 μm or so, so thin
Particle can be directly entered alveolar, the weld fumes of long-term suction high concentration, and it can be made in pulmonary deposition, cause electric welder pneumoconiosis.
Welding shop is often accompanied by a large amount of weld fumes and produced, if welding shop is only with opening up skylight and side window etc., by workshop
The inorganization ventilation circulated naturally of air, dust removing effects are poor, and weld fumes will diffuse whole workshop, environment in production process
More severe, serious harm workman is healthy, accordingly, it would be desirable to special ventilating system be set to welding shop, to ensure work
Industry environment.
For the improvement of dust in industrial dedusting, typically by Partial controll dirt source and overall two kinds of sides of general ventilation
Formula is realized.Partial controll dirt source is to set exhaust hood directly to exclude nuisance at flue dust generation, can effectively prevent nothing
Tissue air-flow drives pollutant to spread in space, still, due to the work of welding shop (the particularly welding shop of large span)
Skill is limited, and weldment size is indefinite, welding place is not fixed and welding manner is more, is not appropriate for using Partial controll dirt source
Draft type.And for overall general ventilation, traditional approach is that level blows air in workshop, forms a laminar flow and above push away
Flue dust is drained, that is, workshop bottom send into clean air, workshop top set exhaust outlet using air hot pressing and
Air-supply jacking excludes flue dust plus the swabbing action of top exhaust outlet, is watered down with clean air, dilutes nuisance, displacement is logical
Wind, weld fumes and the volume to weight ratio atmospheric density of the mixed mixed gas of air are big, therefore weld fumes has nature decline to become
Gesture, and welding shop is not belonging to hot-working workshop substantially, therefore workshop hot pressing is smaller, is excluded flue dust using nature hot pressing several
Impossible, this draft type is very undesirable for the higher welding shop of height (generally height is in more than 10m) effect, nothing
Method reaches requirement.
