Concrete technical scheme

By the following examples feature of the present invention and other correlated characteristic are described in further detail, so that technical staff's of the same trade understanding:

Shown in Fig. 1-8, label 1-24 represents respectively: body 1, clarifier 2, top cover 3, blower fan 4, separator 5, activated carbon filter layer 6, photocatalyst purifying layer 7, air compartment 8, anion generator 9, ventilating opening 10, ventilating opening 11, ventilating opening 12, case 13, baffle plate 14, base 15, oil suction felt pan 16, purification cassette 17, dividing plate 18, NACF felt 19, photocatalyst web plate 20, uviol lamp 21, packing ring 22, screw 23, slit 24.

The clarifier 2 of present embodiment is loaded on the inlet of body 1, and clarifier 2 is made up of separator 5, activated carbon filter layer 6 and photocatalyst purifying layer 7, and the three from inside to outside, is set gradually by the inlet beginning.Separator is divided into eight unit, each unit is made up of case 13, baffle plate 14, base 15 and oil suction felt pan 16, oil suction felt pan 16 places baffle plate 14 tops, case 13 is trapezoidal with the cross section of base 15, constitute slit 24 between the two, case 13 is located by connecting with packing ring 22 and screw 23 each other with base 15, can regulate the width of slit 24 by the height that changes packing ring 22.Activated carbon filter layer is made up of NACF felt 19 and dividing plate 18, and the two be arranged in parallel, and its median septum 18 is a corrugated board.The photocatalyst purifying layer is by nano-TiO ₂Photocatalyst web plate 20 and uviol lamp 21 are formed.Clarifier 2 is box-like and places in the air compartment 8, and anion generator 9 is housed after the clarifier 2.

Separator uses " inertial separation " or is referred to as " impact demist " principle work, during work, the slit 24 that flue gas forms between the case 13 of separator 5 and base 15 quickens to enter the space that enlarges several times downwards, speed slows down and is subjected to the restriction of the base plate of case 13 and baffle plate 14 and turns around upwards, because the rapid change of speed and direction, oil droplet can increase and the base plate and baffle plate 14 surfaces that rush at case 13 because of inertia and gravity effect are collected in the flue gas, long-pendingly promptly can downward landing enter in the lubricating cup along the inclined-plane to a certain amount of.Remove than the flue gas of larger oil droplet along baffle plate 14 when up, be subjected to the stopping and break-in of oil suction felt pan 16 on baffle plate 14 tops again, oil suction felt pan 16 is made by the high oil-absorbing material, flue gas less oil droplet in knockout process also is adsorbed down, substantially, there is not oil so leave the flue gas of separator 5, enter activated carbon filter layer 6 again, flue gas is when contact NACF felt 19, remaining a small amount of mist of oil and various toxic and harmful and peculiar smell is adsorbed and removes, enter purifying layer 7 then, at the nano-TiO that is equipped with uviol lamp 21 ₂The toxic and harmful and the peculiar smell of trace in the flue gas further removed in photocatalyst web plate 20 effect down, and kill bacteria, virus.So far, through the gas of deep purifying carry negative aeroion by blower fan 4 suction pressurization backs from body 1 top perforate 10, left and right side perforate 11, left and right 12 discharges of perforate down form three-dimensional powerful air curtain, can effectively stop flue gas to leak.The air curtain that top perforate 10 constitutes also plays the effect that operator and flue gas are isolated, and is much cleaner.Purify back gas and be inhaled into again, circulation in forming in company with driveing flue gas.
