Abstract
This invention discloses channel radial trunk diesel vehicle tail gas particle filter device of environmental devices composed of rough filter screen and fine filter screen mounted on the case package plate. When the gas is exhausted from the engine enters from the inlet and goes out through outlet, the tail gas particles are captured by the filter screen to be purified to prevent it from pollution to environment.
Description
Technical field:
The invention belongs to the environmental protection equipment scope, particularly the single channel circular radial cartridge type particulates in exhaust gas from diesel vehicle filtrating equipment used of diesel car tail gas refining.
Background technique
Though the appearance of diesel engine is later than petrol engine, rely on its good power character, Economy and durability to be widely used in various power plant, but the pollution that the diesel engine vent gas particle emission causes has become the bottleneck that the restriction diesel engine is further used.At present, diesel particulate filter (diesel particulate filter, hereinafter to be referred as DPF) be to generally acknowledge effective post-processing technology, it is conceived to established particulate is handled, by means such as interception, deposition with particles agglomerate in the diesel exhaust gas in filter.After particulate accumulation arrives to a certain degree, be removed with means such as burnings again so that filter can continue to use just so-called regeneration.
Application at present and research filter structural type the most widely are the wall-flow type structures.It is cellular that filter integral body is multichannel, then these parallel channels carried out alternate plug-hole.The standard product of external existing this structural type.But the wall-flow type structure does not have flexible flexible space originally as a rigid construction when being subjected to external impacts.In addition, diesel exhaust gas will experience a diffusion and the process passed through in porous medium, and particle deposition is constantly arranged in this process, makes the wall-flow type structure cause bigger back pressure loss, and promptly the impact force that is subjected to of conduit wall is bigger.So, this structure of wall-flow type structure filter except causing bigger back pressure loss, to the requirement of mechanical strength of dielectric material also than higher.
Also have a kind of filter structure of axial filtering type, diesel exhaust gas is entered by inlet, passes through filter medium along the direction of central shaft, discharges via outlet.Axially the filter inside of filtering type is porous structure, and many apertures are arranged, and hole diameter is generally 0.2mm-2mm, and each aperture links to each other with other apertures by opening, constitutes the passage of many complications.The filter of this form, more many greatly than the micropore of the used porous medium of wall-flow type structure filter.The long distance because filter internal channel winding complex, particulate are difficult to advance is so major sedimentary is at the front end of filter.This has just caused the entry end of soot particle bulk deposition in filter, results in blockage.It is too fast that the direct result of bringing thus is exactly the exhaust back pressure rising, has to regenerate, and this makes that the effective volume of whole filter reduces on the one hand, has in fact only utilized a part of front end of filter; Frequent on the other hand regenerative process will shorten the working life of filter and increase energy consumption.
Summary of the invention
The purpose of this invention is to provide and the particulate matter in the exhaust emissions of diesel engine is captured filtration, a kind of single channel circular radial cartridge type particulates in exhaust gas from diesel vehicle filtrating equipment that the minimizing particle emission pollutes environment.This device is made up of circular cone tube, shell and compound web plate filter layer, it is characterized in that: this device is connected the shell two ends by air inlet circular cone tube and exhaust circular cone tube and the filter layer that is contained in the shell is formed; Engine exhaust enters from filter inlet, and through compound web plate, the particulate matter in the exhaust is trapped capture, and the exhaust after the filtration is discharged by middle passage again.
Described filter layer is that the coarse filtration web plate is encapsulated on the plectane with thin screen pack, and its position can be exchanged, and the also corresponding thereupon exchange with the exhaust passage of gas-entered passageway.
The used material of described compound web plate comprises the complex metal wire-mesh filtering material, metal fiber felt filtering material, the composite felt filtering material of ceramic fiber blanket filtering material and steel fiber and alumina fibre shuffling.
The invention has the beneficial effects as follows by the filtration of thick, the thin two-layer compound web plate in cylinder cover exhaust gas from diesel vehicle, engine exhaust gas particulate is captured on the filter, stop it to enter the endoatmosphere, purified the particulate matter in the exhaust gas from diesel vehicle well, reduce environmental pollution, help health of people.
Description of drawings
Fig. 1 is a single channel circular radial cartridge type particulates in exhaust gas from diesel vehicle filter apparatus configuration schematic representation.
Embodiment
Figure 1 shows that single channel circular radial cartridge type particulates in exhaust gas from diesel vehicle filter apparatus configuration schematic representation.This device is connected shell 4 two ends by air inlet circular cone tube 1 and exhaust circular cone tube 8 and the filter layer that is contained in the shell is formed, coarse filtration web plate 5 outside, fine filtering web plate 3 is fixed on the back encapsulation disk 7 with one heart interior, the other end is by the fixing two layers of mesh Board position of preceding encapsulation disk 9, and seal the centre gangway mouth of suction port end, the cylindrical 5 of back encapsulation disk and the exhaust port side of shell 4 link together.Engine exhaust enters external chennel 2 from circular cone tube 1, and enter fine filtering web plate 3 from coarse filtration web plate 5, the filtration of the composite filter material of process metal composite web plate or other types, composite filter material comprises the complex metal wire-mesh filtering material, the metal fiber felt filtering material, the composite felt filtering material of ceramic fiber blanket filtering material and steel fiber and alumina fibre shuffling.Particulate matter in the exhaust is trapped on coarse filtration, the compound web plate of fine filtering, discharges by middle passage 6 through the engine exhaust that filters again.
Coarse filtration web plate 5 among Fig. 1 can be exchanged with the position of thin screen pack 3 on encapsulation plectane 7,9, and gas-entered passageway 1 also corresponding thereupon exchange with exhaust passage 8.
