The specific embodiment
The of the present invention structure expressed as Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention is a kind of environmental protective oil fume extraction apparatus, its prior art feature comprises smoke collecting device 13, fume extractor 14, is used for the place that family, restaurant or other industrial production have flue dust and mist of oil to produce.Its smoke collecting device 13 is the ends that air inlet 24 are located at blast pipe 6, and by flue dust and the mist of oil inspiration blast pipe 6 of blower fan with the operating position generation, and the exhaust duct 8 that passes through in the fume extractor 14 is discharged flue dust.Also need to be provided with blower fan on the exhaust duct 8.
Technical problem to be solved by this invention is to reduce the discharging of flue dust and mist of oil, and the recycling of waste oil, so taked following technical scheme: establish sump oil filter 15 between described smoke collecting device 13 and the fume extractor 14 in the above, this device is established the Rose Box 5 of sealing, memory box has filtered fluid 7, its liquid level and box top have a space, stretch into the bottom surface that filtered fluid 7 approaches casing with blast pipe 6 mouths of pipe of smoke collecting device 13 UNICOMs, on the mouth of pipe, be provided with blast pipe filter mantle 1, be very fine and closely woven guard on this blast pipe filter mantle 1, the end face of casing is provided with the exhaust duct 8 with fume extractor 14 UNICOMs.Above-mentioned filtered fluid 7 can adopt clear water generally speaking, plays the effect of absorption sump oil.Under the acting in conjunction of air intake blower fan and air draft blower fan, the gas that contains flue dust and mist of oil that the operating space produces enters Rose Box 5 by blast pipe filter mantle 1, and is drawn out of and enters exhaust duct 8.Gas becomes a lot of tiny bubbles when the blast pipe filter mantle 1, and gas fully mixes with liquid and contacts, and makes liquid better to the adsorption effect of flue dust and mist of oil.Because what filtered fluid 7 adopted is clear water, and the density of oil is less than water, so sump oil 12 always floats over the top of liquid.
In order to realize the recovery of sump oil 12, sump oil filter 15 also is provided with blowdown oil device 16, this device communicates with the top, side of Rose Box 5 by blowdown oil pipe 17, check valve 9 is established in position near Rose Box 5 on blowdown oil pipe 17, its through-flow direction is for being to flow to blowdown oil device 16 from Rose Box 5, and the sump oil 12 that flows out from blowdown oil pipe 17 enters sump oil case 11.The liquid level of sump oil 12 reach a certain height, just can be by this device with its discharge.The effect of check valve 9 is that Rose Box 5, the perhaps suction of air are got back in sump oil 12 refluences when preventing fan operation.
Because in use, liquid is that clear water volatilizees to some extent, might discharge certain filtered fluid 7 at 12 o'clock at blowdown oil in addition, so need to replenish filtered fluid 7.If do not replenish, the viscosity of sump oil is too big, and the fluid thickness causes the big increase of resistance of filtering, and filter effect descends.Sump oil filter 15 is provided with liquid supply device 19, and inserts Rose Box 5 by liquid supplementation pipe 20, and another termination of liquid supplementation pipe 20 has the fluid pipeline of pressure, and disconnected by the 21 control liquid circulations of fluid infusion motor switch.Actual liquid supplementation pipe 20 is as long as insert the just passable of running water system, and its pressure can meet the demands.
Owing to be provided with check valve 9 in the blowdown oil pipe 1, certain resistance is arranged, so sump oil 12 self is can not flow to sump oil case 11, this just need be provided with oil drain pump 10 in blowdown oil pipe 17, the operation of the motor of oil drain pump 10 is subjected to the control of level control circuit 18.
When absorption sump oil 12 more, when liquid level is increased to high liquid level (HLL) inductor 4 positions in the Rose Box 5, liquid level inductor 4 sends signal and gives liquid level control circuit 18, level control circuit 18 makes the motor of oil drain pump 10 connect running, and oil drain pump 10 enters sump oil case 11 with too much sump oil 12 by check valve and blowdown oil pipe 17;
Said process makes liquid level decline in the Rose Box 5, and when reducing to normal level of liquid inductor 3 positions, liquid level inductor 3 sends signal and gives liquid level control circuit 18, and level control circuit 18 makes the motor of oil drain pump 10 disconnect stall, stops oil extraction;
Because liquid is the clear water loss of volatilizing to some extent, liquid level descends in the Rose Box 5, when liquid level is reduced to low liquid level inductor 2 positions, low liquid level inductor 2 signals to level control circuit 18, level control circuit 18 makes fluid infusion motor switch 21 connect liquid supplementation pipe 20, mends running water into cleaning from running water system;
Above-mentioned fluid infusion process makes in the Rose Box 5 liquid level be increased to normal level of liquid inductor 3 positions from low, and at this moment, normal level of liquid inductor 3 signals to level control circuit 18, and level control circuit 18 makes fluid infusion motor switch 21 disconnect liquid supplementation pipe 20, stops to replenish running water.
Aforesaid operations also can pass through Artificial Control fully, does not promptly adopt level control circuit 18, but according to liquid level variation, opens different switch or motor.At this moment each circuit is independent control, and is unrelated.This just need make Rose Box 5 parts transparent, perhaps the position that can observe of the outside of Rose Box 5 establish with case in be communicated with and be transparent level scale display tube, with the convenient variation of observing liquid level.The level scale display tube is vertical the setting.But such method has increased personnel's workload, and control accuracy is not high.
In filtered fluid 7, the flue gas of rising is from tiny bubble, and progressively merging becomes air pocket mutually.In order to make bubble become minute bubbles again, be provided with one or more layers filter 22 in the Rose Box 5, filter 22 is parallel to liquid level, and filter 22 is provided with densely covered a plurality of little through hole.Air pocket becomes minute bubbles again after passing aperture.The number of plies of filter 22 is set according to the needs of filter effect.Can also play the effect that prevents that liquid from seething with excitement in case.
The cross section of a direction of filter 22 is a plurality of waveforms of " W " shape continuously.Take the purpose of this technical measures to be to increase the path of bubble in filtered fluid, bubble is more fully contacted with filtration, filter effect is better.
In the smoke collecting device 13, the air inlet 24 of blast pipe 6 is one or more.Air inlet 24 all is located at the oil smoke nidus, i.e. cooking stove position, general portion placed on it; Air inlet 24 quantity can be one; When big the or cooking stove area of exhaust gas volumn is big sometimes, also adopt two or more air inlets 24.
When the big and stove top of needs exhaust smoke level is subjected to the structural limitations distance far away, air inlet 24 can be located at the side of operating space, blast pipe 6 is the level of state in this position.Can press close to the oil smoke occurrence positions more like this, improve lampblack-pumped effect.
In flue gas, also have the dust of some and sink to the bottom of Rose Box, so the bottom of Rose Box 5 is provided with bleeder plug 23.Through after certain service time, can screw off bleeder plug 23, the dirt of bottom is discharged, screw on bleeder plug 23 then, and mend an amount of clear water.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
