The utility model has the advantages that the design is novel; the structure is simple and reasonable; the occupation of land is small; the installation is convenient; harmless clean gas is extracted and can meet the requirement of the environmental protection; the applicability is strong; the efficiency is high; the utility model is suitable for various hotels, restaurants, dining rooms, food processing industries, industrial shops and mines for the filtration and the purification of harmful dust and gas.

Description

A kind of environmental protection type oil fume filtering and purifying

The utility model relates to a kind of environmental protection type oil fume filtering and purifying, belongs to the ventilation unit class, is specially adapted to the discharging of harmful soot gas in the kitchen of each large, medium and small type hotel, restaurant, restaurant and enterprise and institution and the food-processing industry.

Each office building, large halls and guest houses, shop and general catering trade department and food processing industry all are the straight-lines that adopt ventilation fan, range hood etc. to the discharging of harmful soot gas at present, though can get rid of the soot gas of processing site, but can't absorb, decompose, purify the harmful soot gas that is produced in the process of manufacture, to the environment of atmosphere periphery and comprise that human body, animal and plant etc. all produce and directly pollute and harm, the discharging of unit ventilation fan simultaneously, be subjected to the certain influence of external condition, shortcomings such as effect is low, and service life is short.

The purpose of this utility model is to provide that a kind of adaptability is strong, rational in infrastructure, simple, efficient is high, can absorption, decomposition, purifying oil fume gas, reach indoor no oil smoke, outdoor free of contamination environmental protection type oil fume gas discharging apparatus.

The technical solution of the utility model comprises soot gas capturing device, conveying device, oil filter, clarifier and induced-draft fan, capturing device is made of multistage induced-draft fan and smoke evacuation arm, be pooled to the smoke exhaust pipe of conveying device, through oil filter oil, aqueous vapor are filtered, clarifier is handled the absorption of the harmful substance in the soot gas, decomposing, purifying through multistage scavenging solution, and pure harmless clean gas is discharged through induced-draft fan and smoke exhaust pipe.

Further describe the utility model and provide embodiment below in conjunction with accompanying drawing.

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model capturing device schematic diagram.

Among the figure: 1-induced-draft fan, the 2-arm of discharging fume, 3,4,8,10,15, the 16-smoke exhaust pipe, 5-coagulates oily sheet, 6-screen pack, 7-fuel reserve tank, 9-induced-draft fan, 11-purifying box, 12-partition panel, 13-scavenging solution, 14-dividing plate.

Present embodiment is the purifier for filtering oil smoke that a soot gas capturing device is made up of the level Four capturing device, every grade of capturing device is made up of induced-draft fan 1 and smoke evacuation arm 2, every grade of smoke evacuation arm is pooled to the smoke exhaust pipe of conveying device, what of oil smoke capturing device progression can be provided with arbitrarily according to the situation of production site, from two-stage to six grade or manyly all can.

Conveying device is a smoke exhaust pipe, can be according to situation on the spot with the different of equipment configuration and flexible arrangement, and smoke exhaust pipe is provided with oil filter, clarifier and induced-draft fan, the smoke evacuation pipeline of an integral sealing of formation.

Oil filter comprises condensate oil cooler 4, fuel reserve tank 7, described condensate oil cooler is a T shape threeway member, being provided with up and down in the interface that intersects, the two-layer venetian blind type that intermeshes coagulates oily sheet 5, the two ends of level are connected with smoke exhaust pipe 3,16 respectively, end opening links to each other with fuel reserve tank 7, is provided with screen pack 6 and oil exit pipe and valve in the fuel reserve tank 7.

Clarifier comprises purifying box 11 and scavenging solution 13, described purifying box 11 is made up of 2～5 not connected lattice, every lattice are conical bottom, delivery pipe and valve are established in the awl end, be convenient to wash residue, middle dividing plate 14 is lower than case lid, be convenient to flue gas and pass through, remove first especially, every lattice center has a partition panel 12 contour and go deep in the scavenging solution with casing, form the passage that flue gas enters another scavenging solution, every lattice are provided with the device that injects scavenging solution on the casing, and casing is provided with the cover plate of sealing, and every lattice inject different scavenging solutions 13 in the case, case lid is provided with two holes, wherein a hole is an air admission hole, is located at first lattice, on the hole, all connect smoke exhaust pipe 16 down, 15, smoke exhaust pipe 15 should be deep in the interior scavenging solution 13 of case in the case, another hole is a venthole, be located at the partition panel of last lattice after, be connected with induced-draft fan 9 with smoke exhaust pipe 10.

The soot gas that produces, suck smoke evacuation arm 2 through induced-draft fan 1 and be pooled to smoke exhaust pipe 3, through oil filter with the oil in the flue gas, the cohesion of impurity such as aqueous vapor, be deposited on the screen pack, deposit fuel reserve tank in, flue gas after the oil removing enters in the scavenging solution of clarifier, by chemical method,, absorb respectively through 2～5 grades, decompose and filter, purify different hazardous compounds, present embodiment is 2 grades, purify what of progression, the difference decision according to institute's smoke discharging composition removes and deoils, water and smell, hazardous compound and dust, impurity, pure harmless clean gas is discharged by smoke exhaust pipe 8 through induced-draft fan 9.

In sum, the utility model modern design, simple and reasonable, easy for installation, but wall hanging takes up an area of few, can be provided with arbitrarily according to field condition and customer requirements, can remove oil, water in the flue gas, smell and harmful compound, discharge be harmless clean gas, the demand that adapts to environmental protection fully, adaptability is strong, and the efficient height also is applicable to simultaneously filtration, the purification of harmful dust gas between worker outside the soot gas, mine car.
