(5) specific embodiment
Embodiment is referring to Fig. 1, and 1 is the airduct that is communicated with kitchen range top top exhaust fume collecting hood and reclaiming clean case among the figure.The 2nd, oil smoke reclaiming clean case.The 3rd, be fixed on the ring flange on the cabinet exterior interface, in order to be connected with airduct 1.The 4th, be fixed on the ring flange on the cabinet wall interface, in order to be connected with impact tube 5 in the case.The 6th, the shower nozzle that is connected with impact tube.The 7th, decontaminating liquid.8 are mounted in the outer transparent communicating pipe that is communicated with decontaminating liquid in the case of case, in order to liquid level in the indication case.The 9th, filling opening when in the case during scavenging solution insufficient height, can add scavenging solution by this mouthful.The 10th, overflow launder when liquid level is higher than overflow launder in the case, can makes the fluid of unnecessary recovery overflow automatically by this groove and flow in the oil storage tank 11.The 12nd, fuel outlet valve by this valve, can reclaim the waste oil of collecting.The 13rd, antinose-dive leg.The 14th, liquid barrier.The 15th, filter adsorption layer.
Whole workflow is as follows: blower fan connects the exhaust fume collecting hood of kitchen range top top by airduct, the negative pressure suction that the high velocity air that contains oil smoke and peculiar smell that the kitchen range top is sent here is produced by blower fan, by airduct 1, enter the impact tube 5 in the oil smoke reclaiming clean case, enter in the scavenging solution 7 or directly impact liquid above liquid level through shower nozzle 6, the air-flow that contains oil smoke and peculiar smell evokes a large amount of liquid mists and foam in reclaiming clean casing 2.Oil smoke particulate in the air-flow is cleaned liquid and fully absorbs in case.Be trapped after being with the scavenging solution mist by retaining liquid companion in the ascending air, flow back in the scavenging solution again.Be trapped down the liquid fog body of being with, by filtering adsorption layer 15, further purified again, be discharged in the atmosphere at last.
Referring to Fig. 2,61 is the connectors that are connected with impact tube among the figure, the 62nd, and the outer round platform shell of shower nozzle, the 63rd, the interior round platform shell of shower nozzle.The focused airflow of coming from impact tube is clipped in annular flow between the inside and outside two round platform shells by interior round platform shell branch.Such design makes focused airflow enter scavenging solution in the mode of comparatively disperseing, and helps the raising of purification efficiency.
Referring to Fig. 3,141-liquid barrier frame, the 142-secured in parallel bending lath on frame among the figure.When the air communication that rises from the below is crossed slit between these bending laths, because inertia, the liquid fog particles in the air-flow will strike on the plate, and then assemble and grow up, and fall back in the scavenging solution down at last.The negligible gas molecule of inertia then can pass through smoothly.
In order to guarantee purification efficiency, must control airflow direction and the speed that enters in the decontaminating liquid.Consider that from clean-up effect air-flow should enter liquid with the angle that is basically perpendicular to liquid level, the angular range of airflow direction and liquid level should be 20 ° to 160 °.Air velocity is too low, and clean-up effect is poor.But speed is too high, and windage is too big, and clean-up effect descends on the contrary, and discharges air-flow and can attach too many liquid mist, is difficult for holding back.Best air-flow admission velocity scope is 3 meter per second to 50 meter per seconds.
In order to guarantee purification efficiency, also must export in subsurface distance by the control shower nozzle.Distance is too short, and clean-up effect is poor.Distance is oversize, and promptly air-flow enters under the liquid too deeply, and purifying rate can obviously not improve, and windage but greatly increases.Best distance range should be 10 millimeters to 200 millimeters.For guaranteeing a constant optimum distance, along with the increase of holding back fluid in the case, perhaps allow unnecessary fluid discharge at any time outside the case, shower nozzle perhaps constantly raises.This just needs the special mechanism of design to reach the purpose of automatic control.High especially for air velocity, as situation, shower nozzle can be placed on the liquid level more than or equal to 40 meter per seconds, from liquid level distance with 0 to 100 millimeter for well.
In order effectively to reclaim the waste oil resource, avoid secondary pollution, improve purification efficiency, decontaminating liquid can be selected pure water, contains the water of emulsifying agent or directly adopt the waste oil that reclaims from oil smoke.Because the nonwetting property of oil and water adopts pure water to make scavenging solution, clean-up effect is relatively poor.But waste oil of holding back in the case and water have obvious layering, carry out waste oil easily and reclaim.Employing contains the water of emulsifying agent as scavenging solution, and then purification efficiency is higher, but the waste oil recovery difficult is big.Best choice is directly to adopt waste oil as scavenging solution.Mist of oil particle in fluid and the oil smoke has good associativity on the one hand, and the larger oil droplet that pours in the fluid mixes with oil immediately, and less mist of oil particle is then adhered to by the oily foam of boiling easily.Thereby clean-up effect will be better than emulsified water liquid.On the other hand, the difficulty that does not have waste oil recovery and secondary pollution again.
In order to guarantee clean-up effect preferably, must guard box in scavenging solution foam and ascending air abundant blending space and interaction time are arranged.This just need consider in design that liquid level is to the enough height between the liquid barrier in enough volumes of reclaiming clean case and the case.The former is relevant with compressor flow, and culinary art kitchen range eye is many more, and required flow is big more, and the volume of reclaiming clean case also should be big more.No matter capacity how, the scavenging solution horizontal plane is not less than 500 millimeters to the height between the liquid barrier in the reclaiming clean case.
For guaranteeing clean-up effect preferably, the air-flow of going out from shower nozzle in the form of a ring or other dispersed enter scavenging solution or directly impact and purify liquid level.Disperse to enter than concentrate enter good.This just requires the design of shower nozzle that the focused airflow of impact tube was scatter before entering scavenging solution as far as possible.
For making the air-flow of discharging not contain the scavenging solution mist substantially from the reclaiming clean case, top at oil smoke reclaiming clean case is provided with liquid barrier, this liquid barrier is made of many bending plates that are arranged in parallel, behind the slit of ascending air in the reclaiming clean case by these bending plates formations, the liquid fog particles of being with will be trapped.The designing requirement of liquid barrier can effectively catching liquid mist, can not cause excessive windage again.A kind of design is to adopt many bent plates that are arranged in parallel to hold back, and utilizes the inertia of liquid fog particles, because of the bump bent plate is built up the whereabouts, thereby separates with the minimum gas molecule of inertia.
Purify cost for guaranteeing clean-up effect, reducing, used filtering adsorbing material is activated carbon, silicone jelly, activated alumina or molecular sieve.
For guaranteeing the constant shower nozzle outlet and the optimum distance of liquid level, along with the increase of holding back fluid in the case, perhaps allow unnecessary fluid discharge at any time outside the case, shower nozzle perhaps constantly raises.At oil smoke reclaiming clean lower box part overflow launder and oil storage tank are set, make the height of overflow launder consistent with the scavenging solution level altitude in the required reclaiming clean case, along with the increase of holding back fluid in the case, allow unnecessary fluid overflow at any time and flow in the oil storage tank by overflow launder, wait to be recycled.
