Description
Technical field
The utility model relates to the device of diesel engine exhaust automatic cycle regeneration, relates in particular to infrared purification apparatus of diesel engine exhaust gas.
Background technique
Up to now, using maximum diesel exhaust aftertreatment technology in the world at present is that the employing steinheilite is the micro particle catching filter of main raw material, the wall that this particulate is arranged in a row filter is a porous ceramics, in two adjacent passages, the outlet side of the passage position that is blocked, and the suction side of another passage is plugged.This just force exhaust by inlet open passage enter, passes the porous ceramics wall and enter adjacent outlet open walk, and particulate just is filtered on the conduit wall mouth.This micro particle catching filter is higher to the filter efficiency of soot.But the micro particle catching filter can only filter out particulate and be deposited in the cell walls from the exhaust of diesel engine, it self can not remove particulate, along with the particulate of duct inner accumulated constantly increases, as untimely removing, just cause exhaust back pressure to increase inevitably, influence the ventilation charge of diesel engine, power sharply descends down, fuel consume increases, burn deterioration, and exhaust emission is even more serious.
Therefore, must in time remove the particulate in the particle trapper, work on enabling, remove the particulate that accumulates in the particle trapper and be called regeneration.The existing micro particle catching regeneration method that adopts in countries in the world mainly contains following two kinds:
1, be called disclosed method and the device that utilizes the exhaust gas heat purifying exhaust air of exhaust gas purifier for internal combustion engine as Japan Patent JP special permission 9-280035 invention disclosed name, its structure as shown in Figure 1.The quartz ball 12 of the hollow that comprises housing 11 and be provided with in housing and the quartz fibre that is provided with at inlet end, buffering thermal accumulator constitute.Though this patented technology has certain purifying effect, but because it adopts diameter less than in the 3mm, wall thickness is the hollow quartz ball technological scheme of 0.3mm only, cause the infrared rays emitted energy low because of thin-walled, a little less than, heating-up temperature is subjected to the variation of delivery temperature and fluctuates very big in the thermal capacity dingus tube, owing to be hollow shape and thin-walled again, when bubble is expanded by elevated temperature heat and the impact of the strong pulsating wave of exhaust and broken wall is cracked, be directed at by the integral honeycomb shape structure of the intensive filling of hollow quartz spheroid of intensity fragility and destroyed the essence defective that can't overcome hollow ball monomer weak structure.
2, adopt the method for interrupted thermal regeneration, promptly particle trapper adopts electric heating, microwave heating or burner heating after every work a period of time, eliminates the method for particulate.Be the way that adopts electric heating regeneration as shown in Figure 2, its structure is, constitutes by ceramic honeycomb filter core 21 and at the electric heating wire 22 of the end setting of the honeycomb hole of this ceramic honeycomb filter core.As everyone knows, the key element of particulate oxide is high temperature, oxygen enrichment and oxidization time.Be more than 5% for example at oxygen concentration, in the time of more than delivery temperature＞650 ℃, the oxidation of particulate also need be experienced 2min/ minute, and the delivery temperature characteristic of diesel engine is generally less than 500 ℃, and diesel engine for automobile is normally moving its row's temperature mostly generally only below 400 ℃ under the medium and small loading condiction, the exhaust flow velocity is also very high, thereby does not take technological innovation to be difficult to burn particulate under current conditions, often can cause fuel economy and exhaust emission further to worsen again as improving engine exhaust temperature.
And when reality is used the thermal regeneration mode, need a whole set of complicated control system, and also need to consume extra energy simultaneously, as electric energy or pluralities of fuel, make the complicated operation cost very high.For solving above problem, the applicant once was 200520045446.2 at application number, proposed a new technological scheme in the patent application of denomination of invention for " diesel engine exhaust regeneration filtration, purification silencer ", the major character of this technological scheme comprises cellular heat purifying instrument 31, ceramic wall streaming filter 32 and the mixed oxidization silencing apparatus 33 of adding that order is communicated with as shown in Figure 3.Wherein: the described cellular heat purifying instrument 31 that adds comprises shell 311 and the cellular quartz ball of formation that is provided with in the enclosure or the assemblying body 312 of quartz pushrod or quartz ball and quartz pushrod, and described quartz ball is a solid ball.This utility model patent utilizes infrared materials quartzy itself and cellular structure, absorbs waste-gas heat and produces the high-energy infrared rays to the exhaust flow heat temperature raising, makes particulate fire burns and oxidation, in time removes the particulate that deposits in the catcher/filter automatically.Though effectively harmful the discharging pollutants in the purifying exhaust air, the effect of this purifying exhaust air can also further improve and improve.
