Description
Technical field
The present invention relates to a kind of large area uniformly to descend air draft workbench, and specifically a kind of harm of poison protection is unilateral
The large area of air draft uniformly descends air draft workbench, belongs to occupational disease protection technology field.
Background technology
Occupational hazard protection is increasingly subject to the attention of employing unit, in ceramic glazing, case and bag shoemaking brush coating, organic solvent
Allocation process can produce substantial amounts of toxic gas, diffuse to Work places, influence workers ' health, the ceramic glazing in part, case and bag system
Shoe brush glue, organic solvent allotment discharge poisonous substance caused by operation process using top-draught hood, although top-draught hood can discharge toxic gas,
But the breathing zone of people is between pollutant and top-draught hood, i.e. the downwind side of pollutant, although cause the poisonous substances of Work places by
Discharge, but the occupational exposure level of worker does not reduce, and adds worker and suffers from occupational disease and occupation occurs
The risk of sick hazardous accidents.There is worker to enter around workbench when ceramic glazing, case and bag shoemaking brush coating, organic solvent allotment operation
Row operation, and because organic solvent density ratio air is big, ceramic glazing, case and bag shoemaking brush coating, organic solvent allotment Work places
Air draft is suitably carried out using lower suction hood, excludes poisonous substance caused by production process, and can effectively avoid worker's breathing zone positioned at pollution
The technical barrier of thing downwind side.
Current ceramic glazing, case and bag shoemaking brush coating, the workbench of organic solvent allotment operation are typically only work support and put down
Platform, air draft toxicological operation protective system is not provided with, and area of work increases.Traditional lower air draft area of work is smaller, using intermediate row
Wind mode realizes the uniform air draft of whole work top, due to ceramic glazing, case and bag shoemaking brush coating, organic solvent allotment operation work
Make table top product greatly and height of table is limited, unilateral air draft can only be taken to realize the air draft gas defence of workbench, so as to lead to not
Air draft is carried out by the way of air draft under centre, and unilateral air draft is difficult to realize the uniformly lower air draft of whole large area workbench.
Using that can cause during unilateral air draft, air draft workbench under large area is bigger than normal in close exhaust outlet side wind speed, away from exhaust outlet side
Substantially there is no wind；If increasing exhaust amount, large area workbench can be caused excessive close to exhaust outlet side wind speed, away from exhaust outlet one
Crosswind speed is too low, it is difficult to realizes away from the wind speed needed for exhaust outlet side, and energy consumption is significantly increased.Due to being difficult to large area
Wind speed of the workbench needed for away from exhaust outlet side, so as to cause the poisonous substance of whole work top to be difficult to effectively control, so that it is dirty
Operating environment is contaminated, increase worker suffers from occupational disease and the risk of Accident occurs, and there is an urgent need to realize using unilateral
The uniformly lower air draft of large area workbench, solves large area workbench poisonous substance protection question during air draft.
