Abstract
The kitchen oily fume purifier consists of circular water spraying cooler, cyclonic separator, adsorption tower, blower and connecting pipeline. The circular water spraying cooler includes one circular water trough with oil draining valve and water draining valve on the side wall, one connected spraying and washing tower with oily fume pipe and blower, and pipeline with circular water pump and nozzle in between. The cyclonic separator is communicated with the water trough and the spraying and washing tower via pipeline, and is also connected to the adsorption tower. The adsorption tower is provided with exhaust pipeline in the lower part and the pipeline has blower in the outlet and water discharge valve. The present invention has simple structure, high oily fume purifying efficiency and less environmental pollution.
Description
Technical field
The present invention relates to a kind of purifier of oil-containing flue gas, particularly relate to a kind of purifier of oil-containing flue gas for kitchen use.
Background technology
As everyone knows, family, restaurant and food processing place in the food cooking process, can produce a large amount of oil-containing flue gases.General people directly are discharged into this oil-containing flue gas outdoor, this is contaminated air and building on every side not only, and the harmful substance that is contained in the oil smoke also can have influence on the healthy of people, eliminates or reduce the oil-containing flue gas pollution of environment is more and more obtained people's attention.
People are to use a kind of range hood that has filter screen to the method that reduces the oil-containing flue gas at present, this range hood is that wire netting or papery filter screen were set before the import blower fan of oil smoke hood, so that the oil-containing flue gas condensing of inspiration is become in the liquid back inflow feeder or with oil smoke directly to be adsorbed on the papery filter screen.Metal mesh filter oil-containing fume cleaning efficient is low, and only about 50% of purifying oil fume; The papery filter screen can very fast absorption oil smoke reaches full and closes, and for improving its purification efficiency, then will frequently change the papery filter screen, trouble and increase use cost.Recently occurred static again and removed the mist of oil clarifier, although it makes moderate progress to removing the oil smoke effect, static captures oil smoke needs the regular hour, be subjected to the restriction of device size, its clean-up effect is not very good yet, and electrode surface also adsorbs grease easily, still needs cleaning frequently.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of effective combination of passing through the purification techniques of recirculated water drip washing, cooling, cyclonic separation and absorption is provided, strengthen purifier oil-containing fume cleaning.
For achieving the above object, the present invention takes following design: the present invention is made up of recirculated water drip washing cooling device, cyclone separator, adsorption tower, water pump, blower fan and connecting pipe.Described cycling elution cooling device is provided with an eluting column that communicates with this tank at a recirculated water above with tank, article one, the end that the pipeline of water circulating pump is housed is connected the bottom of described tank, the other end feeds the top of eluting column hermetically, and at its mouth of pipe shower nozzle is housed.On the sidewall of described tank, be provided with fuel outlet valve and recirculated water discharging valve.Be equiped with the oil-containing flue in the bottom of described eluting column, and on this pipeline, the inlet blower fan be housed.Cyclone separator communicates with described tank, eluting column by pipeline, is connected with adsorption tower by pipeline simultaneously, and the bottom of described adsorption tower is equiped with discharge duct, is provided with outlet blower fan, water leg and discharging valve on this pipeline.
Operation principle of the present invention is, the oil-containing flue gas that is produced by the kitchen enters eluting column by pipeline under the promotion of inlet blower fan, in the inlet fan starting, water circulating pump starts, water in its tank pumps in the eluting column, enter oil-containing flue gas in the eluting column and in the process that rises, be subjected to the drip washing cooling of water, part falls in the tank, part enters cyclone separator by pipeline, this cyclone separator rotation is the oil that enters in it, the shredded tobacco for water pipes mist carries out vapour, liquid separates, play the isolation of purified effect again, the Purge gas of coming out from cyclone separator, enter into the adsorption tower that adsorbent is housed, strengthen catharsis, make the gas of the gas of discharge near cleaning to small mist of oil in the gas.Because cycling elution and cyclonic separation, the clearance rate of mist of oil can reach more than 96% in the gas, has alleviated the purification burden of adsorbent, has prolonged the replacing time of adsorbent, and described adsorbent can be an active carbon etc.The oil-containing flue gas that the kitchen produces, through behind the purifier of the present invention, the clearance rate of mist of oil can reach 99% in the gas.
The present invention reduces gas by resistance that adsorbent layer produced, make the purifier exhaust unobstructed, adopt two blower fans to discharge system, respectively be provided with a typhoon machine at the entrance and exit place of purifier, its scavenging action more produces effect than the simple power that strengthens the inlet blower fan.
This device also can be used for purifying equipment and the place that other produces the oil-containing flue gas.
The present invention is simple in structure, purifies oil-containing flue gas efficient height, and it is clean to purify the gas of discharging the back, and environmental pollution is little.

Fig. 1 represents structural representation of the present invention
The specific embodiment
As shown in Figure 1, the present invention is made up of recirculated water drip washing cooling device 1, cyclone separator 2, adsorption tower 3, blower fan 4,5, water circulating pump 6 and connecting pipe 7.Described cycling elution cooling device 1 is provided with an eluting column 12 that communicates with this tank at a recirculated water above with tank 11, article one, the end that the aqueduct 13 of water circulating pump 6 is housed is connected the bottom of described tank 11, the other end feeds the top of eluting column 12 hermetically, and at its mouth of pipe shower nozzle 8 is housed.On the sidewall of described tank 11, be provided with fuel outlet valve 111 and recirculated water discharging valve 112.Be equiped with oil-containing flue 7 in the bottom of described eluting column 12, and inlet blower fan 4 is arranged on this pipeline.Cyclone separator 2 communicates with described tank 11, eluting column 12 by pipeline 7, is connected with adsorption tower 3 by pipeline 7 simultaneously, and the bottom of described adsorption tower 3 is equiped with discharge duct 31, is provided with outlet blower fan 5, water leg 311 and discharging valve 312 on this pipeline.
Operation principle of the present invention is as follows: the oil-containing flue gas sucks recirculated water drip washing cooling devices 1 by oil-containing smoke inlet pipeline 7 by smoke inlet blower fan 4, at first by eluting column 12 drip washing of lowering the temperature.Drip washing recirculated water is delivered to cat head drip washing shower nozzle 8 ejections of eluting column 12 by water circulating pump 6 by circulating water chennel 11, be back to circulating water chennel 11 after the drip washing, gas after the drip washing enters into cyclone separator 2 by eluting column 12 and carries out centrifugation, the liquid of separating is by pipeline 7 reflux cycle tanks 11, and the gas after the separation enters adsorption tower 3 and carries out the adsorption cleaning processing.Purge gas after the adsorption treatment is delivered in the atmosphere through pipeline 31 by 5 exhausts of outlet blower fan.Steam condensation in the Purge gas is catchmented in water leg 311 and can be emitted by discharging valve 312.Fuel outlet valve 111 on the sidewall of described tank 11 and recirculated water discharging valve 112 can be emitted the oil of condensation in the tank 11 and the recirculated water that changes the outfit.
