Abstract

The utility model discloses a compound oil-fume purifying machine which is composed of a tank body, an atomizing spray nozzle 1, a charcoal cage 3, a surfactant liquid tank 2, an oil dirt recovery tank 8, honeycomb frame-shaped filter tanks 12, 13, a circulating pump 6 and a draught fan 16, wherein the inner part of the tank body is divided into an upper part and a lower part by a water receiving disk 5 from top to bottom; the tank body above the water receiving disk is divided into a left part and a right part by a baffle plate, and the bottom parts of the left part and the right part are communicated with each other. The atomizing spray nozzle is fixed at an air inlet on the top end of the tank body, and the charcoal cage is fixed on the lower end of the atomizing spray nozzle; charcoal or coke is arranged in the charcoal cage; a decentralized net 2 is fixed between the atomizing spray nozzle and the charcoal cage; a V-shaped air and liquid damping net 4 is arranged between the charcoal cage and the water receiving disk; the filter tanks are arranged on the right side of the tank body and on the water receiving disk; an air outlet on the filter tanks is provided with the draught fan; the surfactant liquid tank and the oil dirt recovery tank are arranged below the water receiving disk. The oil-fume purifying machine not only can purify the harmful fume of oil in the oil fume, but also can convert other poisonous gas ingredients into harmless ingredients.

Description

The composite smoke purifying machine

One, technical field

The utility model relates to a kind of fume purifier of fume.

Two, technical background

At present both at home and abroad the cooking fume control equipment produced of enterprise adopt more electrostatic, this equipment in use owing to can deposit greasy dirt in the flue gas around the electrode, make the clean-up effect instability, need frequent cleaning electrode, particularly the Chinese cooking custom is high oily, and this problem is appeared suddenly more.The cleaning equipment of this form can not reclaim waste oil in addition, fails pernicious gas is handled.Also have a kind of activating agent fountain design, washing has certain effect to oil gas, but to wherein not effect of poisonous and harmful composition.Also have in addition and adopt the design that adds catalyst burning oil smoke, its cost height, and easily cause secondary pollution.

Three, summary of the invention

The purpose of this utility model provides a kind of composite smoke purifying machine, and it has overcome above various type existing problems, and each type advantage has been carried out good comprehensive.

For realizing this purpose, the technical scheme that the utility model is taked is, adopt efficient surfactant, after atomizing, contact with flue gas, in a special charcoal or coke cage, coke falls into the greasy dirt collection box after with oil droplet in the oil smoke and the absorption of other organic matter, so the flue gas after being purified cellular frame Rose Box of parallel airflow through being made up of the activated carbon fiber that is loaded with low temperature catalyst again, BaP in the flue gas and dibenzanthracene are adsorbed to fall, simultaneously with CO, N _xBe converted into CO ₂And N ₂Deng gas, thereby reach the purpose that oil smoke is purified.

Characteristics of the present utility model are except the oils harmful smoke in the oil smoke is purified, also other toxic gas composition in the flue gas to be converted into outside the harmless composition discharge machine simultaneously.

Five, the specific embodiment

Fig. 1, composite smoke purifying machine shown in Figure 2 is by casing, atomizer 1, charcoal cage 3, surfactant liquid case 2, greasy dirt collection box 8, cellular frame Rose Box 12 and 13, circulating pump 6 and air-introduced machine 16 are formed, offer the door that freely to close and to open before the casing, in the casing and in the door noise reduction encapsulant 14 is housed, be divided into two parts by a drip tray 5 up and down in the casing, casing above the drip tray has been divided into left and right sides two parts that the bottom is communicated with by plate washer, two-part top, the casing left and right sides has flue, and exhaust outlet flange 17 is housed respectively, air inlet flange 18 is convenient to connect with the intake and exhaust pipeline, so just formed from the air inlet on the top in casing left side, downward through the casing left space, connected entrance on water-accepting board to the right again, right space through casing makes progress again, to the gas outlet formation gas flue on case top; Atomizer is fixed on the air inlet place on casing top, and its lower end is fixed with the charcoal cage, and charcoal or coke are housed in the charcoal cage; Be fixed with decentralized network 2 between atomizer and charcoal cage, play the even effect of loosing of atomized liquid; Place a V-type gas-liquid damping screen 4 under the charcoal cage and between drip tray, prevent that liquid from splashing everywhere; Be placed with the cellular frame Rose Box of parallel airflow that the activated carbon fiber by being loaded with low temperature catalyst of two-layer drawer type is formed on casing right side, the drip tray; Air-introduced machine is equipped with at place, gas outlet on the Rose Box, guarantees to form windstream, and flue gas after being purified is discharged; Be placed with surfactant liquid case and greasy dirt collection box under the drip tray, drip tray above the surfactant liquid case has recovery holes, make the liquid that falls within drip tray flow back to the surfactant liquid case, the surfactant liquid case is communicated with by cross over pipe 22 with the top of greasy dirt collection box, and the greasy dirt that the surfactant liquid case is reclaimed in the liquid flows in the greasy dirt collection box; Surfactant liquid case and greasy dirt collection box are respectively equipped with liquid level meter 20,21, are convenient in good time supplementary table surface-active agent and cleaning greasy dirt; Circulating pump is promoted to atomizer with the liquid in the surfactant liquid case, forms fluid circulation system.

During work, open air-introduced machine and circulating pump, oil smoke enters smoke purifier through air inlet, the efficient surfactant of atomizer ejection, contact with flue gas and to react, and further contact in special charcoal or coke cage, coke falls into the greasy dirt collection box after with the absorption of the oil droplet in the oil smoke and other organic matter, flue gas after being purified like this is the cellular frame Rose Box of parallel airflow through being made up of the activated carbon fiber that is loaded with low temperature catalyst again, with the benzo in the flue gas] pyrene and dibenzanthracene adsorb to fall, simultaneously with CO, N _xBe converted into CO ₂And N ₂Deng gas, through air-introduced machine it is discharged, reach the purpose that oil smoke is purified.
