Accompanying drawing explanation
Fig. 1 is the structural representation of vacuum water wash-out smoke exhaust described in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, described vacuum water wash-out smoke exhaust, comprise the casing 2 that stores water 1 and the radome fairing 4 in order to collect flue gas, exhaust outlet 3 is offered at the top of casing 2, in casing 2, be provided with jet pump 5 and submerged pump 6, the inlet of submerged pump 6 is immersed in water 1, and the liquid outlet of submerged pump 6 is connected by the inlet of connecting pipe 21 with jet pump 5, the air inlet of jet pump 5 is connected with radome fairing 4 by admission line 7, and the gas-liquid mixed outlet of jet pump 5 is immersed in water 1, in the present embodiment, casing 2 sidewall is provided with overfall 10, overfall 10 is positioned at the top of the liquid level of casing 2 water 1, like this when kitchen fume is passed into after in water 1, because the density of water 1 is greater than oil, oil can float on the water and form oil reservoir, and oil reservoir liquid level is higher than after overfall 10, and oil reservoir can flow out from overfall 10, in the present embodiment, below overfall 10, and the casing 2 being arranged in the gas-liquid mixed outlet top of jet pump 5 is provided with current stabilization net 16, due to submerged pump 6 and jet pump 5 in running order time, can constantly the water 1 in casing 2 be extracted out and return in casing 2, cause the solution fluctuation of water 1 in casing 2 large, not only bad for water 1 and oily stratification, and easily make water 1 enter standing oil trap 9 from overfall 10, thus reduce the content of oil in standing oil trap 9, and then the organic efficiency reduced oil, after current stabilization net 16 is set, by the obstruct cushioning effect of current stabilization net 16, effectively can reduce the undulate quantity of water 1, have and be not only conducive to water 1 and oily stratification, also reduce water 1 in casing and enter the probability of standing oil trap 9 from overfall 10, thus the organic efficiency that improve oil, in the present embodiment, standing oil trap 9 is had in the arranged outside of casing 2, casing 2 is connected by the top of overfall 10 with standing oil trap 9, the lower sides of standing oil trap 9 also offers the refluxing opening 11 be connected with casing 2, refluxing opening is provided with and only allows water 1 to enter the one-way check valve 12 of casing 2 from standing oil trap 9, because the density of oil is little compared with water, meeting stratification after oil and the mixed solution of water enter standing oil trap 9 from overfall 10, be divided into upper strata oil reservoir and lower aqueous layer, the water of lower aqueous layer can reenter in casing 2 through refluxing opening 11 and one-way check valve 12 and be recycled, in the present embodiment, oil-out is offered in the bottom of standing oil trap 9, oil-out is connected with pipeline 15 of draining the oil by fuel outlet valve 14, when the water major part of the lower aqueous layer after stratification in standing oil trap 9 is after refluxing opening 11 and one-way check valve 12 are back to and are recycled in casing 2, fuel outlet valve 14 can be opened, the oil in upper strata oil reservoir in standing oil trap 9 is collected recycling, in the present embodiment, radome fairing 4 is connected by gas collection air channel 8 with admission line 7, and the kitchen fume entered like this in radome fairing 4 can first concentrate in gas collection air channel 8, and then considerably increases the collection treatment effeciency of equipment to kitchen fume, in the present embodiment, offer inlet and liquid outlet respectively at the upper/lower terminal of casing 2 sidewall, inlet is connected with input duct 18 by liquid feed valve 17, and liquid outlet is connected with fluid pipeline 20 by bleeder valve 19, water in casing 2 can be regularly replaced like this, easy to operate, when actual installation, radome fairing is installed on the top of the kitchen range top, so that collect oil smoke, casing 2 is installed in the cabinet below the kitchen range top or outdoor, thus greatly reduces room noise,
Operation principle of the present utility model is as follows: the kitchen fume of the kitchen range top being cooked generation moves upward and enters radome fairing 4, and be concentrated in gas collection air channel 8, start submerged pump 6, submerged pump 6 by the water in casing 2 from its inlet suction, jet pump 5 is sprayed into through connecting pipe 21 from the inlet of jet pump 5 again from the liquid outlet of submerged pump 6, then from the gas-liquid mixed outlet ejection of jet pump 5, spray into from the inlet of jet pump 5, the water velocity of ejection is exported quickly again from gas-liquid mixed, air in jet pump 5 can be taken out of by current when the gas-liquid mixed outlet of jet pump 5 sprays simultaneously together, thus make to form negative pressure in jet pump 5, kitchen fume in such gas collection air channel 8 can enter jet pump 5 along admission line 7 under suction function, and the gas-liquid mixed outlet ejection together from jet pump 5 under the drive of the current passed through from jet pump 5 enters water, along with jet pump 5 constantly exports injection water to its gas-liquid mixed under submerged pump 6 coordinates, the kitchen fume entering gas collection air channel 8 from radome fairing 4 can constantly enter water, complete the aspiration procedure to kitchen fume, can be washed by water filtration after kitchen fume enters water, namely a large amount of particulates, soluble gas and oil in kitchen fume can be put to stay in water and form oil-water mixture, and in kitchen fume, remaining clean non-solubility gas can enter air from the exhaust outlet 3 of casing 2, because the density of oil is little compared with water, oil in oil-water mixture in casing 2 can float and form upper strata oil reservoir and lower aqueous layer, along with kitchen fume constantly continues to enter in casing water, in casing 2, the upper strata oil reservoir of oil-water mixture can thicken and go up, when the liquid level of upper strata oil reservoir goes up to overfall 10 position, upper strata oil reservoir in casing 2 can flow into from overfall 10 and leave standstill oil trap 9, because submerged pump 6 and jet pump 5 in use easily cause the fluctuation of oil-water mixture in casing 2, when undulate quantity is large, lower aqueous layer in casing 2 also can enter standing oil trap 9 from overfall 10, thus make also to be oil-water mixture in standing oil trap 9, just in this oil-water mixture, the content of oil is greater than the content of water, due to standing oil trap 9 for separate space can not be subject to the impact of submerged pump 6 and jet pump 5, the liquid level of the oil-water mixture thus left standstill in oil trap 9 does not have large fluctuation, make the oil-water mixture in standing oil trap 9 that good stratification can occur, namely be divided into upper strata oil reservoir and lower aqueous layer, and the lower aqueous layer left standstill in oil trap 9 can be back to casing 2 from refluxing opening 11 and one-way check valve 12 and recycles, after the water major part in lower aqueous layer in standing oil trap 9 is back to casing 2, fuel outlet valve 14 can be opened, the oil in standing oil trap 9 in the oil reservoir of upper strata be discharged through fuel outlet valve 14 and pipeline 15 of draining the oil and leaves standstill oil trap 9, and can recycling, when the water in casing 2 uses a period of time to need to change, submerged pump 6 can be made to quit work, open bleeder valve 19 again, water in casing 2 is discharged casing 2 by bleeder valve 19 from fluid pipeline 20, when the water in casing 2 drains only, close bleeder valve 19, and open liquid feed valve 17 simultaneously, water is entered casing 2 from input duct 18, thus complete change water operation.The utility model has the advantages that: (1) structure is simple, and manufacturing cost is low, installation and maintenance are convenient; (2) oil in kitchen fume can not only be recycled, and effectively can filter a large amount of particulates in kitchen fume, reduce the fraction of particle entered in air; (3) noise is little, reduces noise to the impact of surrounding environment; (4) owing to not installing any equipment in radome fairing, and then the easy to clean to radome fairing is made.
