Abstract
The invention discloses a terminal purifier for tail gas exhausted by vehicles. The terminal purifier is mounted behind a three-way catalytic converter. On a tail section of an exhaust tube, exhaust gas exhausted by an engine is converted by the three-way catalytic converter, so that the exhaust gas is greatly purified but certain pollution exists and part of CO, NO2, HC, carbon micro particles and the like are exhausted. At present, the number of the vehicles is huge and the vehicles seriously pollute low altitude; particularly when people have higher requirements on the quality of air, the problem in purifying the tail gas of the vehicles at high quality is required to be solved. The terminal purifier for the tail exhausted by the vehicles, which is provided by the invention, aims at solving the difficult problem. According to the terminal purifier, due to the adoption of advanced technologies such as physical adsorption, photocatalysis, and photodestruction, the exhaust gas is further subjected to oxidation reduction under the severe conditions of about 200DEG C, so that high-quality purification for tail gas is realized, and a novel situation for environment-friendly governance of the tail gas of the vehicles is opened.
Description
Technical field
The present invention relates to purifying vehicle exhaust.The technical field that purifies again of the waste gas after ternary catalyzing unit purifies particularly
Back of the body border technology.
The current vehicles enormous amount, greatly this advances in the pollution of exhaust after ternary catalyzing unit is handled, but still atmosphere is formed severe contamination.Especially people are increasingly high to the atmospheric mass requirement, and high-quality automotive exhaust gas is still a difficult problem, need idea go to solve.
Summary of the invention
The invention provides the terminal purifying device that a kind of Vehicular exhaust is handled again, can solve an above difficult problem.The present invention has comprehensively adopted waste gas absorption, photocatalysis, ultraviolet cracking.New and high technologies such as selectivity desorption, make HC in the tail gas, CO, NOx carbon particle etc. further redox become H
2O, N
2And CO
2, the tail gas HQ high quality is purified.
Terminal purifying device of the present invention is contained in after the ternary catalyzing unit, and the rear of outlet pipe is characterized in that: some thin layer adsorbent sheet are housed in metal shell, and these adsorbent sheet have been mixed with photocatalyzer; Their alternate successively strings are on quartz burner, and during energising, ultraviolet is impinged upon on each layer wall by the interlayer space; When tail gas gets into each layer; Accomplish absorption at each layer successively, photocatalysis, photodestruciton, last redox become nontoxic H
2O, N
2, CO
2,Discharge outside the car behind the desorption.
The terminal purifier, wherein: UV lamp is no cap lamp, which is mounted on one than it is long, single-head opening protective glass tube, inside a fiberglass cloth cover end sleeve anti-Huang, the outer end top of asbestos in the protection of glass tubes on a cork.
Said terminal purifying device is characterized in that: protect the seal head end of glass-tube, withstand on the interior location of taper hole asbestos packing of metal shell inwall, the perforate asbestos packing of opening end on another wall of shell passes, and combines closely air tight between their holes.
Described terminal purifying device; It is characterized in that: the ballast of ultraviolet lamp is contained in the protection box, and on this box-packed support outside the metal shell end face, it is heat insulation to add one deck asbestos packing during installation; Protect the bottom surface of box just in time to withstand on the asbestos bottle stopper this moment, to avoid the protecting glass-tube string moving.
The terminal purifying device of being told is characterized in that: in the asbestos bottle stopper 4 apertures are arranged on the protection glass-tube, the ballast in 4 leads of quartz burner pass aperture and protect box links to each other, and two power lines of ballast are connected with this car generator.
Said terminal purifying device is characterized in that: according to different couplings, adsorbent can be activated carbon, Y type alundum (Al, fluorite etc., and photochemical catalyst can be titanium dioxide TiO
2, palladium Pa, platinum Pt etc.
Described terminal purifying device is characterized in that: metal shell is to be processed by mirror finished stainless steel, the reflective photodissociation effect that strengthens of inner face.
Beneficial effect of the present invention is to have solved three-element catalytic can't solve vehicle fully, and the difficult problem of tail gas pollution has provided new direction of HQ high quality purifying vehicle tail gas.
Description of drawings
Below in conjunction with accompanying drawing and embodiment, further specify.
Accompanying drawing one is embodiment's a structural representation.
Accompanying drawing two is embodiment's middle-ultraviolet lamp light tube assembly figure.
Among Fig. 1, metal shell 1, outlet pipe 2, ballast protection box 3, asbestos bottle stopper 4; Ballast 5, heat insulation asbestos packing 6, support 7, preceding silk screen apical ring 8 is mixed with the adsorbent sheet 9 of photocatalyzer; Silk screen isolating ring 10, protection glass-tube 11, back silk screen apical ring 12, taper hole asbestos packing 13; Perforate asbestos packing 14, pressing plate 15, quartz burner 16, glass cloth cover 17.
Specific embodiments
Through Fig. 1, combination Fig. 2, before the metal shell encapsulation, the perforate asbestos packing 14 of packing in proper order, pressing plate 15; Before silk screen apical ring 8, be mixed with the adsorbent sheet 9 of catalyzer, silk screen isolating ring 10, back silk screen apical ring 12; Taper hole asbestos packing 13, package casing after assembling is accomplished, in Fig. 2, quartz burner 16 puts glass cloth cover and inserts protection glass-tube 11; After asbestos bottle stopper 4 imports 4 leads of quartz burner, fill in protection glass-tube 11 openings, the protection glass-tube is inserted in the metal shell by the hole of opening asbestos packing 14, and put in place; On support 7, adorn heat insulation asbestos packing 6 in regular turn, ballast protection box 3, ballast 5 connects the lead rear seal-cover.
After being contained in ternary catalyzing unit to the terminal purifying device that assembles, the outlet pipe rear, the outlet pipe polyphone with the terminal purifying device is connected the ballast power line again with this generator line.One works as vehicle launch, ultraviolet lamp work, and ultraviolet is by separated each the sorbent aspect that illuminates of each interlayer; The catalyzer that coupling is arranged in the sorbent under the irradiation of ultraviolet, has possessed photocatalysis; The photodestruciton ability, when engine exhaust passed through, the harmful matter CO in these waste gas, NO, HC, charcoal cigarette particulate etc. all adsorbed in each layer sorbent; The photocatalysis cracking, the photochemistry of redox desorption and physical reactions are because adsorbent layer is numerous; When waste gas passed through the terminal purifying device, through repeatedly combined reaction, the most above-mentioned harmful matter was converted into CO
2, N
2, and H
2O.
Because the inner face of metal shell is a mirror finished stainless steel, has strengthened uitraviolet intensity, and is energy-conservation again.
Since preceding silk screen apical ring 8, silk screen isolating ring 10, and silk screen apical ring 12 is processed by silk screen, does not increase gas-flow resistance.
Because exhaust temperature reaches as high as 300 degrees centigrade, so all liners constitute by resistant to elevated temperatures asbestos product.
