A kind of oil mist eliminator
Technical field
The present invention relates to a kind of clarifier, relate in particular to a kind of oil mist eliminator.
Background technology
At present, bore at turnning and milling in the process of metal working such as mill, due to the use of metalworking fluid, make to form in air a large amount of oil mist particles, in workshop, in air, the maximum distribution of mist of oil particle diameter is 1 μ m, research shows, the pellet of particle diameter below 10 μ m can go directly and be deposited on lung and cause bad reaction, particulate is less, contained polycyclic aromatic hydrocarbon and heterocyclic compound are more, endanger also larger, even can cause the illness such as lung cancer, therefore, the oil mist concentration of controlling metal job shop is to be worth plant manager, the common problem of paying close attention to of occupational safety and health management organization.
Oil mist eliminator is installed in workshop, and the airborne mist of oil of elimination, in order to improve workshop condition, is the method that workshop adopts mostly now thereby reduce oil mist particles on the impact of workers ' health, but, traditional cleaning equipment purification efficiency is low, and energy consumption is high, easily produces secondary pollution.
Meanwhile, existing oil mist eliminator, because assembling is at filter plant rear, causes equipment outlet noise larger, and some oil mist eliminator outlet noise is even up to 90 decibels, and high-decibel noise is particularly serious to hearing impairment, has a strong impact on people's health.
Summary of the invention
For addressing the above problem, the invention provides a kind of by assembling the oil mist eliminator in air-intake device, make blower fan be placed in filter front with reduction equipment outlet noise, reduce the noise pollution in workshop, meanwhile, filter is three grades of filtrations of going forward one by one, to improve purification efficiency.
For achieving the above object, the technical solution used in the present invention is: a kind of oil mist eliminator, comprises air-intake device, filter and exhaust apparatus;

Further, exhaust apparatus outer wall arranges power on switch.
Beneficial effect of the present invention is:
Assembling of the present invention is in air-intake device, the noise at air intake place is owing to being directly connected by pipeline with lathe, noise enters sealing lathe inside, small to external environment influence, meanwhile, assembling is in filter front, noise is subdued step by step in oil mist eliminator, particularly fore filter, fillter section and post-filter stop noise, and noise of equipment can be reduced more than 15 decibels, have greatly reduced the noise pollution in workshop condition.
Blower fan in the present invention is preposition, and under the centrifugal action of draught fan impeller, larger oil mist particles is separated, then filters step by step through fore filter, intermediate filter and post-filter, has improved the filter efficiency of oil mist eliminator.
