Description
Technical field
The utility model relates to a kind of purifying processing device of flue gas, relates to a kind of cooking fume spray purifying column for carrying out purified treatment to heat-treatment oil smoke specifically.
Background technology
Oil smoke is important atmosphere pollution, and composition is more complicated, containing a large amount of harmful materials, before oil smoke discharge, needs to carry out purified treatment.Wherein wet sprinkling purifying column is generally primarily of cyclic water tank, packing layer, demist layer, the compositions such as air exhauster.Air exhauster, generally at spray column rear portion, provides power for cooking fume moves.Water circulating pump draws water from cyclic water tank, and water is sprayed on packing layer by nozzle, and flue gas enters from below, contacts with shower water at packing layer, is adsorbed with water, and completes the purification of oil smoke.After purification, flue gas moves upward, and by demist layer, after removing water smoke, is discharged by blower fan.Because filler space is less, the viscosity of oil smoke strengthens, and use for a long time, filler space can be blocked by mist of oil, makes equipment lose effect.In addition, owing to not having flue gas even distribution structure or distribution equalizing structure to design unreasonable, make the smoke distribution through packing layer uneven, cause clean-up effect poor.
Summary of the invention
The purpose of this utility model provides for weak point existing in above-mentioned prior art the cooking fume spray purifying column that a kind of structure is more reasonable, clean-up effect is better just.
The purpose of this utility model realizes by following technique measures:
Cooking fume spray purifying column of the present utility model comprises the cyclic water tank, the first packing layer, the second packing layer that set gradually from the bottom to top and is positioned at the demist layer at top; Between cyclic water tank and the first packing layer, be provided with flue gas even distribution mechanism, described cyclic water tank by cleaning water tank, the first circulating box, the second circulating box, water separation tank four part form; Wherein said cleaning water tank is the independent water tank with heating function arranged, and is connected respectively with corresponding connecting line by scavenging pump with the spray equipment being arranged on first and second packing layer top; Described first circulating box is communicated with the second circulating box bottom, and the second circulating box is communicated with water-oil separating upper box part, and directly over the second circulating box with the intracavity inter-connection of flue gas even distribution mechanism; The first described circulating box is connected with the spray equipment being arranged on first and second packing layer top with corresponding connecting line respectively by spray pump; Oil-water separator is provided with in described water separation tank; Oil pump and corresponding connecting line is caught up with for being pumped into by the water in water separation tank in second circulating box to being provided with between water separation tank at the second circulating box.
The mechanism of flue gas even distribution described in the utility model comprises shell body, inner housing, the equal flow be arranged on equal mode for cloth in the circular air inlet chamber that is jointly made up of inner housing outer wall and shell body inwall; Described equal flow employing is bent backward by air inlet and the mode that length increases gradually is arranged; The upper end in described circular air inlet chamber is enclosed construction, and lower end is connected with the second circulating box; Described air inlet is arranged on the tangential direction in described circular air inlet chamber.
The mechanism of flue gas even distribution described in the utility model inner housing is identical with the intracavity diameter of described first packing layer, and is combined in the mode of close fit by connector.
The inner housing of the mechanism of flue gas even distribution described in the utility model also can adopt following structure to realize: namely the inner housing of flue gas even distribution mechanism is made up of the downward-extension section of the first packing layer chamber wall.
Operation principle of the present utility model is as follows:
Oil smoke entering with the air inlet of tangential direction setting from flue gas even distribution mechanism, rotates along the equal flow increased gradually around length uniform in circular air inlet chamber and advances, cooking fume is distributed on around each orientation in circular air inlet chamber.Move downward after cooking fume is uniform, the bottom walking around the inner housing of uniform mechanism enters in the inner chamber of uniform mechanism, moves up into spray column then.Described flue gas even distribution mechanism can make flue gas be uniformly distributed in spray column cross section on the one hand, and flue gas is when equal flow rotates advance on the other hand, and due to centrifugal action, part of smoke can be adsorbed onto on uniform system shell, plays clean-up effect.
When filler needs cleaning, the heater work in cleaning water tank, rinse water heats up, and scavenging pump work, hot water sprays on packing layer by pipeline, completes the cleaning of filler.First circulating box is communicated with the second circulating box bottom, top baffle for separating, play the object that the mist of oil stopping the second circulating box surface enters the first circulating box, the first circulating box is equipped with spray pump, by pipeline Water spray on packing layer, flow back to the second circulating box after adsorbed oil flue gas.Second circulating box is communicated with water-oil separating upper box part, bottom is separated by dividing plate, after equipment runs a period of time, catch up with oil pump to open, the water in water separation tank is pumped in the second circulating box, after the second circulating box water surface is higher than dividing plate, oil slick in second circulating box and water can flow in water separation tank, water separation tank, built with oil-water separator, can be separated the oil in separator box, oil is pulled out outside case with water.
The beneficial effects of the utility model are as follows:
One, owing to cleaning the setting of water tank, efficiently solve because the packing layer that the adhesion of greasy dirt causes blocks, ensure the long-time steady operation of equipment.
Two, flue gas even distribution mechanism can carry out preliminary purification to flue gas on the one hand, makes the smoke distribution entering packing layer more even on the other hand, ensures clean-up effect.
