Accompanying drawing explanation
Fig. 1 is the structural representation of vacuum water eluting smoke exhaust of the present invention.
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, described vacuum water eluting smoke exhaust, including storing the casing 2 of water 1 and in order to collect the trousers 4 of flue gas, air vent 3 is offered at the top of casing 2, being provided with ejector pump 5 and submerged pump 6 in casing 2, the inlet of submerged pump 6 is immersed in water 1, and the liquid outlet of submerged pump 6 is connected with the inlet of ejector pump 5 by connecting pipeline 21, the air inlet of ejector pump 5 is connected with trousers 4 by admission line 7, and the gas-liquid mixed outlet of ejector 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, so after kitchen fume is passed in water 1, owing to the density of water 1 is more 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；nullIn the present embodiment，Below overfall 10、And be positioned at ejector pump 5 gas-liquid mixed outlet above casing 2 in be provided with current stabilization net 16，Due to submerged pump 6 and ejector pump 5 in running order time，Constantly the water 1 in casing 2 can be extracted out and returned in casing 2，The solution fluctuation causing water 1 in casing 2 is big，Stratification not only bad for water 1 with oil，And easily make water 1 enter from overfall 10 and stand oil trap 9，Thus reduce and stand the content of oil in oil trap 9，And then reduce oil recovery efficiency，After current stabilization net 16 is set，By the obstruct cushioning effect of current stabilization net 16，The undulate quantity of water 1 can be effectively reduced，There is the stratification not only contributing to water 1 with oil，In also reducing casing, water 1 enters the probability standing oil trap 9 from overfall 10，Thus improve oil recovery efficiency；In the present embodiment, standing oil trap 9 it is provided with in the outside of casing 2, casing 2 is connected with the top standing oil trap 9 by overfall 10, the lower sides standing oil trap 9 is further opened with the refluxing opening 11 being 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, owing to the density of oil is little compared with water, the mixed solution of oil and water enters from overfall 10 and stands meeting stratification after oil trap 9, it is divided into upper strata oil reservoir and lower aqueous layer, the water of lower aqueous layer can reenter in casing 2 with one-way check valve 12 through refluxing opening 11 and be recycled；In the present embodiment, oil-out is offered in the bottom 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 be 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, trousers 4 is connected by gas collection air channel 8 with admission line 7, and the kitchen fume so entered in trousers 4 can first concentrate in gas collection air channel 8, and then considerably increases the equipment collection treatment effeciency to kitchen fume；In the present embodiment, upper/lower terminal at casing 2 sidewall offers inlet and liquid outlet respectively, and inlet is connected with input duct 18 by liquid feed valve 17, and liquid outlet is connected with drain pipe road 20 by bleeder valve 19, so the water in casing 2 can be regularly replaced, easy to operate；When actual installation, trousers is installed on the top of the kitchen range top, in order to collect oil smoke, casing 2 is installed in the cabinet below the kitchen range top or outdoor, thus greatly reduces room noise；
nullThe operation principle of the present invention is as follows: cooks the kitchen fume of generation on the kitchen range top and moves upward entrance trousers 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，Ejector pump 5 is sprayed into through connecting pipeline 21 from the inlet of ejector pump 5 again from the liquid outlet of submerged pump 6，Then ejection is exported from the gas-liquid mixed of ejector pump 5，Spray into from the inlet of ejector pump 5、Water velocity from gas-liquid mixed outlet ejection is the fastest again，Air in ejector pump 5 can be taken out of when the gas-liquid mixed of ejector pump 5 exports ejection by current simultaneously together，So that ejector pump 5 is formed negative pressure，So kitchen fume in gas collection air channel 8 can enter ejector pump 5 along admission line 7 under suction function，And export ejection entrance water from the gas-liquid mixed of ejector pump 5 together under the drive of the current passed through from ejector pump 5，Along with ejector pump 5 constantly sprays water to the outlet of its gas-liquid mixed under submerged pump 6 coordinates，The kitchen fume entering gas collection air channel 8 from trousers 4 can constantly enter water，Complete the aspiration procedure to kitchen fume；Can be washed by water filtration after kitchen fume enters water, i.e. a large amount of microgranules, soluble gas and oil in kitchen fume can be put and stay formation oil-water mixture in water, and in kitchen fume, remaining clean non-solubility gas can enter air from the air vent 3 of casing 2；Owing to the density of oil is little compared with water, the 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 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 stand oil trap 9, owing to submerged pump 6 and ejector pump 5 in use easily cause the fluctuation of oil-water mixture in casing 2, when undulate quantity is big, lower aqueous layer in casing 2 also can enter from overfall 10 and stand oil trap 9, so that standing in oil trap 9 is also oil-water mixture, simply in this oil-water mixture, the content of oil is more than the content of water；Will not be affected by submerged pump 6 and ejector pump 5 for separate space owing to standing oil trap 9, thus the liquid level standing the oil-water mixture in oil trap 9 does not have big fluctuation, make the oil-water mixture stood in oil trap 9 that good stratification can occur, i.e. it is divided into upper strata oil reservoir and lower aqueous layer, and stands the lower aqueous layer in oil trap 9 and can be back to casing 2 recycle from refluxing opening 11 and one-way check valve 12；After the water major part stood in oil trap 9 in lower aqueous layer is back to casing 2, can open fuel outlet valve 14, the oil made in standing oil trap 9 in the oil reservoir of upper strata is discharged through fuel outlet valve 14 and pipeline 15 of draining the oil and is stood oil trap 9, and can be with 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 drain pipe road 20, after the water in casing 2 drains only, close bleeder valve 19, and open liquid feed valve 17 simultaneously, make water enter casing 2 from input duct 18, thus complete to change water operation.The invention have the advantage that (1) simple in construction, manufacturing cost is low, convenient to install and maintain；(2) recovery of oil in kitchen fume can not only be utilized, and can effectively filter a large amount of microgranules in kitchen fume, reduce and enter the fraction of particle in air；(3) noise is little, reduces the noise impact on surrounding；(4) owing to not installing any equipment in trousers, so make trousers easy to clean.
