Abstract
The utility model discloses a diesel vehicle tail gas clean-up processing device which comprises at least one cylinder body. A plurality of ventilation holes are formed in the cylinder body and are connected to the air inlet end and the air outlet end. The air inlet end and the air outlet end are located at the two ends of the cylinder body. The air inlet end is in an intersected hole sealing mode. The cylinder body is a ceramic cylinder body. The mode that an air inlet end intersected sealing hole is connected with a plurality of cylinder bodies enables exhausting fluid to be smooth, and wide in contact face, so that the diesel vehicle tail gas clean-up processing device can ensure back pressure, capture particles in waste gas and regenerate at the same time, can better absorb solid and liquid particles in diesel vehicle tail gas, improves particle filtering efficiency, reduces particle emission, protects the environment, and saves cost compared with metal materials due to the adoption of a ceramic wall face. By the adoption of the diesel vehicle tail gas clean-up processing device, PM particle emission in tail gas can be reduced, and the tail gas is made to reach the Euro 4 emission standard.
Description
Technical field
The utility model relates to a kind of purification treatment device, particularly a kind of diesel car tail gas refining treatment device.
Background technique
Along with the exhaustion of fossil fuel and the rise of oil price, people's energy-conservation and environmental consciousness improves day by day, diesel engine obtains general development with its fuel economy in recent years, passenger car development is very fast, car and 90% commercial car in Europe 30% are all used diesel engine, the development of China's Diesel Engine After-treatment Technology and the raising of oil product are in rising trend, and within 2012, diesel engine for automobile reaches more than 300 ten thousand.In developed country's emission of diesel engine rules, reached Europe 5 standards, the corresponding Abgasgesetz of China is also more and more tighter, and due to problems such as oil products, Europe 4 standards are not also implemented.Existing light-duty diesel vehicle Europe 4 discharge Diesel Engine After-treatment Technologies are selected metal POC, and backpressure rising, affects filter efficiency and engine power, if select DPF, cost is high, easily sulfur poisoning, cannot adapt to existing oil product and post-processing technology, Economy and using effect are not good.
Model utility content
Goal of the invention: it is high that the purpose of this utility model is to solve existing device for purifying and treating tail gas cost, easy sulfur poisoning, the problem that filter efficiency is low.
Technological scheme: the utility model adopts following technological scheme: a kind of diesel car tail gas refining treatment device, comprise at least one cylindrical body, in cylindrical body, be provided with some vents, each vent includes inlet end and outlet side, perforate of inlet end of described adjacent two vents and another sealing, the equal perforate in described all outlet sides, the inlet end of perforate and the outlet side of perforate connect cylindrical body.
As optimization, described cylindrical body is ceramic cylinder body.
As optimization, described each row/row some vents in perforate of adjacent two inlet ends and another sealing.
Working method: tail gas enters diesel car tail gas refining treatment device by inlet end, mode due to inlet end employing intersection sealing of hole, be perforates of inlet end of adjacent two vents and another sealing, the vent pressure that the vent that two ends are communicated with and one end are communicated with is different, particulate matter in tail gas can be attracted on the sidewall of the vent that two ends are communicated with, clean gas is discharged, simultaneously along with particulate matter increases, the backpressure rising of automotive exhaust catalysis treatment device, when acquiring a certain degree, exhaust gas processing device meeting automatic oil spout, particulate matter in device for purifying and treating tail gas is burnt again, realize regeneration, can continue to recycle.
Beneficial effect: the utility model compared with prior art: the utility model inlet end intersects sealing of hole; can make exhaust fluid unobstructed; contact widely simultaneously, can when guaranteeing back pressure, catch particulate matter regeneration in waste gas, better adsorb solid and liquid particles in exhaust gas from diesel vehicle; improve particulate matter filter efficiency; reduce granular material dischargedly, protected environment, and adopted ceramic wall; than metallic material, saved cost.Use diesel car tail gas refining treatment device of the present utility model, can make tail gas meet Euro IV Emission Standards.

Tail gas enters automotive exhaust catalysis treatment device by inlet end 3, mode due to inlet end 3 employing intersection sealing of holes, the second vent 6 pressure that the first vent 5 that two ends are communicated with and one end are communicated with are different, particulate matter in tail gas can be attracted on the sidewall of the first vent 5 that two ends are communicated with, clean gas is discharged, along with particulate matter 7 increases, the backpressure rising of diesel car tail gas refining treatment device, when acquiring a certain degree, meeting automatic oil spout, particulate matter in device for purifying and treating tail gas is burnt again, realize the regeneration of purifying processing device, process circulation, reach the exhaust emission standard of particulate matter.
Obtain after tested adopting the filter efficiency of a cylindrical body can reach 38%.
As shown in Figure 1, Figure 2, shown in Fig. 4 and Fig. 5, use the cylindrical body providing as embodiment 1, adopt two cylindrical bodies to join end to end, tail gas is carried out to catalytic treatment, between described two end to end cylindrical bodies, leave the gap of 1-2cm.Cylindrical body used herein is ceramic cylinder body.
Tail gas enters automotive exhaust catalysis treatment device by the inlet end 3 of the first cylindrical body 8, mode due to inlet end 3 employing intersection sealing of holes, the second vent 6 pressure that the first vent 5 that two ends are communicated with and one end are communicated with are different, particulate matter in tail gas can be attracted on the sidewall of the vent that two ends are communicated with, clean exhaust emissions, simultaneously along with particulate matter 7 increases, the backpressure rising of diesel car tail gas refining treatment device, when acquiring a certain degree, exhaust gas processing device meeting automatic oil spout, particulate matter in device for purifying and treating tail gas is burnt again, tail gas enters the inlet end (not shown) of the second cylindrical body 9, again repeat above treatment step, filtering effect is improved.
Obtain after tested adopting the filter efficiency of two cylindrical bodies can reach 56%.
