Description
Technical field
The invention belongs to automation control area, be specifically related to a kind of workshop automatic smoke exhausting system.
Background technology
Along with the socioeconomic develop rapidly of science and technology, the application of solder technology is increasingly extensive, as automobile factory, shipyard etc.Because welding is
The work post that labour intensity is larger, and a large amount of toxic metals smog, Welding fume, pernicious gas, spoke can be produced in welding procedure
Penetrate heat, light pollution, have a strong impact on staff and periphery personnel are healthy, therefore must carry out ventilation to welding shop, to get rid of and rare
Release nuisance, set up good welding surroundings.Welding shop due to factory building generally has the features such as space is tall and big, weldment size is indefinite, welding place is unfixing, welding manner is more, and make Room air distribution design chaotic, pollutant is more difficult.Therefore, how economical and effective carries out dust removal by ventilation to welding shop is a difficult problem always.
Domestic and international welding shop smoke treatment method mainly contains:
1, general ventilation cleaning system, general ventilation also claims dilution ventilation, one side clean air, the adverse concentration in dilution room air thing, simultaneously constantly outside contaminated air discharge chamber, the maximum permissible concentration making concentration of harmful substance in room air be no more than sanitary standard to specify.
General ventilation comprises gravity-flow ventilation and force ventilation two kinds of modes.
When determining the ventilation scheme of welding shop, must locate flexibly as the case may be
Reason, several conventional general ventilation scheme is as follows:
(1) gravity-flow ventilation, gravity-flow ventilation does not need consumption of power, is a kind of draft type of economy, generally adopts natural ventilation system for outdoor weld job or the welding of unlimited space.As the application that some For The Factory Roof natural ventilators, femerell are exactly gravity-flow ventilation.But because gravity-flow ventilation is vulnerable to the impact of outdoor weather condition, particularly very unstable in wind-force effect, so then not quite applicable for the factory building of the pollutant such as dust, pernicious gas generation.
(2) side wall is arranged axial flow blower and add natural ventilator (skylight) air draft, the short Single Span Workshop With less to floor space, arranges axial flow blower and can play the effect that good exhaust effect roof natural ventilation (skylight) plays reinforcement ventilation on each welding post top of outer wall.
(3) Induced fan, natural ventilator (skylight or roof ventilator) air draft are set, by installing Induced fan with the draft type of certain jet angle, in injecting chamber, welding flue gas flow direction flows, finally by outside natural ventilator (skylight or roof ventilator) discharge chamber.
(4) roof ventilator supply and exhaust mode, arranges blowing and discharging fan on the roof of welding shop, welds outside cigarette discharge chamber in workshop, reaches the object that workshop dust concentration is reduced.
(5) blowing and drawing ventilation mode, blowing and drawing ventilation is the draft be composited by sub-thread blowout air-flow and sub-thread suction air-flow, because of but a kind of can effectively Control pollution source spread draft type, this draft type arranges blowing mouth on two span centre posts or single span one lateral column (wall), send the fresh air of outdoor introducing, the side wall on air-supply opposite installs the outside air draft of axial flow blower.Be divided into blowing and drawing ventilation system and on a large scale blowing and drawing ventilation system two class among a small circle.
In addition, the exhaust air rate of the full chamber ventilated of welding shop is general all very large, heating districts being used at workshop Inner eycle welding cigarette in workshop by arranging air cleaning unit after purification utensil, both can reach and workshop dust concentration is reduced, and having solved again the object of workshop self-energy loss simultaneously.
2, local ventilation cleaning system
General ventilation air quantity is large, consumption electric energy is many, running cost is high, winter operation is because of needs heating, power consumption is larger, and the dust concentration that can not improve completely when workman breathes in air, adopt local ventilation mode so a large amount of both at home and abroad, namely enclosure is set near weld job point, flue dust diffusion is not waited just it to be drained, exhaust air rate required is like this about 1/3 ~ 1/4 of general ventilation exhaust air rate, and smoke discharging effect is good, fundamentally solves the smoking problem of welder.
Local exhaust system is primarily of exhaust hood, airduct, purifier and blower fan composition, and its design key will according to the form of technological requirement and place situation determination exhaust hood, understands the distribution of smooth near cover mouth, concentration field and formulates corresponding controlled wind speed.The exhaust hood being applicable to collect weld fumes mainly contains three types: capturing hood (comprising side-draught hood and bottom air-suction cover), top air-suction cover, welding booth (a kind of large-scale suction draft cabinet)
Application number is 200820204955.9, and the applying date is that the utility model on December 10th, 2008 relates to a kind of smoke evacuation system being applicable to bonding wire station, comprises a main smoke pipe, a smoke exhaust pipe and a plurality of smoking ozzle be installed on each bonding wire station; This smoking ozzle is communicated with main smoke pipe respectively, this smoke exhaust pipe is communicated with main smoke pipe, and the exhaust opening of this smoke exhaust pipe is provided with efficient discharge fan, so after this efficient discharge starting fan, all suction condition is there is in smoke exhaust pipe, main smoke pipe and smoking ozzle, therefore operator is when smoking ozzle place carries out bonding wire operation, the flue gas produced can carry out in main smoke pipe along with smoking ozzle, then flue gas is discharged via smoke exhaust pipe, thus can ensure that workshop condition is not contaminated, ensure that operating personnel's is healthy.Therefore, this utility model adopts main smoke pipe to carry out each smoking pipeline of branch design, can effectively save tubing and operating cost, and it is little to take up room, meets the needs of enterprise's production now.
Production line automatic fume exhauster of the prior art, mostly simpler and easy, smoke discharging effect is poor, effectively can not reach the effect of cleaning shop.
