Abstract
A wet-type ventilator for lampblack purification relates to a ventilator suitable for lampblack purification of cookers, which comprises an upper cylinder, a lower cylinder, an electromotor, a ventilation impeller, an axle-ended centrifugal pump, an air inlet, an air outlet, a water tank and an axle-ended flume. When the electromotor drives the ventilation impeller and the axle-ended centrifugal pump to rotate in high speed, the cleaning water absorbed by the axle-ended flume and the lampblack dust absorbed from the air inlet are mixed in a channel of the ventilation impeller. Oil and water, by the impinging atomization of the ventilation impeller, forms liquid drops and tangentially enter the upper cylinder together with soot at high speed. Gas-liquid separation and gas-solid separation is realized under the function of a plurality of mechanisms, such as centrifugal force field, upper and lower turning, inner and outer turning, etc. The separated liquid and solid substances flow into the water tank. The oil liquid floating on the water exhausts through a spill box and a spill pipe. The purified lampblack exhausts from the air outlet so that the lampblack can be purified through dewatering, removing the oil and the solid.
Description
Technical field
The utility model relates to a kind of purification ventilation unit of kitchen flue gas, particularly a kind of wet type fume purifying ventilation unit.
Background technology
Press, present known kitchen fume purifier of fume mainly can be divided into dry type and wet type two big classes.The dry type fume purifier of fume has forms such as high-pressure electrostatic formula and charcoal absorption, and the wet type fume purifier of fume then mainly contains filler and adds spray, screen cloth and add forms such as spray and washing.The big and obstruction easily of the general resistance of wet type fume purifier of fume of the prior art, its purification efficiency obviously reduces behind the long-play, therefore needs periodically changed or cleaned filler, and needs other gas-distributing fan.
The utility model content
The purpose of this utility model promptly is to provide a kind of wet type fume purifier of fume of exempting to clean and lack maintenance, to improve its purification efficiency and to make it possess draught capacity.
For achieving the above object, the utility model utilizes upper and lower cylindrical shell, motor, ventilation impeller, spindle nose centrifugal pump, air inlet, air outlet, water tank and spindle nose tank to constitute a kind of wet type fume purifying ventilation unit, upper shell and lower shell are cylindrical shape and interconnect, and the inside top periphery of lower shell is provided with the receipts tank that communicates with water tank; Motor is fixed on the top of upper shell, and its force-output shaft down and stretch in the upper shell; The ventilation impeller is installed in exert oneself axle head and rotated by motor-driven of motor in the upper shell, and its periphery is provided with static impeller cover, certain interval is arranged and form the ventilation impeller channel between impeller and the static impeller cover; The spindle nose centrifugal pump is fixed on the wheel disc end face of ventilation impeller and can rotates synchronously with the ventilation impeller, and its lower end suction inlet stretches in the spindle nose tank, and its top outlet feeds the root of ventilating vane impeller blade inlet; Air inlet is located at the central authorities of lower shell, and it is suitable for reading to communicate with the ventilation impeller channel, and air outlet then is located at a side of lower shell; Water tank is located at the offside of air outlet in the lower shell, and its two bottom sides is provided with water inlet pipe and blow-off pipe relatively, and its outside also is provided with oil spilling case and oil spill pipe; The utilization of spindle nose tank is supported water pipe sleeve and is located at spindle nose centrifugal pump peripheral of air inlet central authorities and is communicated with water tank, and its top is provided with drip ring.
When above-mentioned wet type fume purifying ventilation unit was worked, the spindle nose centrifugal pump was pumped to the rinse water in the spindle nose tank in the impeller and under the bump of the impeller that rotates at a high speed with certain speed and is atomized; Rinse water after the atomizing is mixed with the oil-containing flue gas that is sucked by air inlet and is made flue gas cool-down, oil in the flue gas combines with the rinse water droplet and further is atomized into the profit droplet by bump, and the profit droplet is accelerated in impeller and enters in the upper shell with very high tangential velocity with flue gas; The oil-containing water flue gas that acceleration enters upper shell in centrifugal force field, up and down turn to and inside and outside turn under the acting in conjunction of number of mechanisms and realize gas-liquid separation and gas solid separation.Profit that is separated and solids descend along upper shell inwall eddy flow, and in the receipts tank inflow water tank of lower shell apical margin, the oil that swims on the water surface is discharged through oil spilling case and oil spill pipe, and flue gas after being purified is then discharged through the air outlet of lower shell one side.This shows, and the utility model can make the de-oiling of kitchen flue gas, dewaters and take off the solid purification that realizes.
Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model wet type fume purifying ventilation unit.
