Abstract
The present invention is a kind of long wood-fibred filter core diesel vehicle PM filter, and it includes filtering bodies and filter chamber.Tubular element that filtering bodies is made up of long wood-fibred and glass fibre, wire netting inner frame, wire netting purchasing ore, front and back end cover, kuppe etc. form.Filtering bodies is placed in filter chamber, on the premise of ensureing that filtering bodies is coaxial with filter chamber, seals lid after making filtering bodies and seal with filter chamber's discharge coupling.Whole filter is placed in the relatively low blast pipe rear of temperature.Exhaust gas from diesel vehicle, through kuppe water conservancy diversion, is flowed into internal cavities by filter core cylindrical outer surface, flows out gas outlet.When tail gas flows through tubular element, PM can be by long wood-fibred and glass fiber filter.Particulate matter with filtering increases, and filter core hydraulic performance decline, after reaching operating limit, can more renew filter core, and the filter core after replacing can recycle.Filter core low cost, environmental protection, it is not necessary to change existing vehicle structure, effectively reduces diesel vehicle granular material discharged.
Description
Technical field
The invention belongs to a kind of diesel vehicle exhaust carbon-smoke particle (PM) purifier, be installed to bavin
Oil car engine blast pipe rear, can be with the carbon soot particles in filtered fuel tail gas.
Background technology
With increasing sharply of automobile pollution, air pollution is on the rise, and reduces discharge and becomes
The key subjects being faced by the whole mankind.Compared with gasoline car, exhaust gas from diesel vehicle temperature is relatively low and primary discharge
Thing is PM and NOx.Particulate Trap Technology is that finally to realize that diesel particulate emission controls maximally efficient
With one of simple method.Particulates in exhaust gas from diesel vehicle trap filtering material conventional both at home and abroad at present has violet blue or green
Stone ceramic honey comb and carborundum etc., its manufacturing process is complicated, price is higher, and to diesel oil during use
Sulfur content has higher requirements, and is difficult to promote in China at present.Timber is green material, utilizes timber to develop bavin
Oil tail gas PM purifier, will be greatly lowered the cost of filtering material, form price advantage, meanwhile,
Oil product is required low by this kind of device, is suitable for promoting the use of in China, has important at economical and environmentally friendly aspect
Realistic meaning.
Content of the invention
Long wood-fibred filter core diesel vehicle PM filter, including filtering bodies and filter chamber.Filtering bodies
The tubular element that is made up of long wood-fibred and glass fibre, wire netting inner frame, wire netting purchasing ore, front
Rear end cover, kuppe etc. form.Filtering bodies is placed in filter chamber, is ensureing filtering bodies and filter chamber
On the premise of coaxial, seal lid after making filtering bodies and seal with filter chamber's discharge coupling.Whole filter is put
In the relatively low blast pipe rear of temperature.Exhaust gas from diesel vehicle, through kuppe water conservancy diversion, is flowed into by filter core cylindrical outer surface
Internal cavities, flows to gas outlet.When tail gas flows through tubular element, PM can be by long wood-fibred and glass fibre
Filter.Particulate matter with filtering increases, and filter core hydraulic performance decline, after reaching operating limit, can be changed
New filter core, the filter core after replacing can recycle.
This device is without changing automobile original structure, easy for installation, and filter efficiency is high, exhaust back pressure
Little, low cost, environmental protection, belong to ecological product, can effectively reduce diesel vehicle granular material discharged.
Brief description
Fig. 1 is the filter structure schematic diagram of long wood-fibred filter core diesel vehicle PM filter, 1
Kuppe, seal lid before 2, seal lid, 4 wire netting inner frames, 5 wire netting purchasing ore, 6 long wooden after 3
Fabric filter element, 7 front end faces, 8 rear end faces；
Fig. 2 is filter chamber's structural representation of long wood-fibred filter core diesel vehicle PM filter, 9
Air inlet, 10 gas outlets, 11 discharge couplings.
Detailed description of the invention
Wire netting is made purchasing ore in tubular.By thickness be 0.05-1mm, width be 1-10mm
Long wood-fibred mix with glass fibre, add resin agitating uniform, load purchasing ore in the tubular of wire netting
Centre, drying makes long wood-fibred filter core.Before front and back sealing lid and tubular skeleton respectively with heat-resistant adhesive
End face and rear end face are cemented together, and the front lid that seals places kuppe.Different according to engine displacement, make
The size of filter core is also different.
Filtering bodies is placed in filter chamber, on the premise of ensureing that filtering bodies is coaxial with filter chamber,
Seal lid after making filtering bodies to seal with filter chamber's discharge coupling.The filter chamber being mounted with filtering bodies is placed in exhaust
Pipe rear, tail gas, through kuppe water conservancy diversion, is flowed into internal cavities by filter core cylindrical outer surface, finally flows out
Gas port.When tail gas flows through cylindrical filter body, meeting is by long wood-fibred filter element filtering, thus the purification of diesel tailstock
Aerated particle thing.
