Abstract
The utility model relates to a kind of novel biomass fiber PM filter cleaner with guide vane, and, with the PM filter cleaner of flow guide device and gear shape biomass fiber filter core before filter, it comprises filter chamber and filter; Filter chamber is made up of blade fair water cone, guide vane and filter chamber; Filter is made up of front and back sealing cover, front and rear cover, inner support thing, outer fixing net and the gear shape biomass fiber filter core that is made up of several pair of fold; Two fold moulding on this device filter core outer wall have not only ensured the stable of structure but also have increased effective filter table area; Before tail gas enters filter core, via flow guide device water conservancy diversion drag reduction, and then be uniformly distributed on the effective filtration area of filter core, improved filter element filtering efficiency; Clean gas after filter element filtering flows out from filter core inner cavity, enters atmosphere from relief opening; This device filter efficiency is high, and filter core utilization ratio is good, long service life, and cost is low, and environmental protection can effectively reduce the discharge of diesel-oil vehicle particulate matter.
Description
Technical field:
The utility model relates to diesel engine PM filtrating equipment technical field, specifically a kind of PM filter with flow guide device and gear shape biomass fiber filter core before filter.
Background technique:
Filter is the vitals in diesel-oil vehicle PM filtrating equipment, directly has influence on the problem such as development and environmental protection of diesel-oil vehicle in China in its filter efficiency and working life.At present, the filter cartridge construction that common diesel-oil vehicle PM filtrating equipment uses is solid cylinder, and material mostly is the materials that price is higher, manufacturing process is complicated such as steinheilite, ceramic honey comb and silicon carbide.The structural feature of this filter is: intensity is high, good heat resistance, structural stability; Shortcoming is: cost is little compared with high, effective filter table area, and filter element filtering burden is large, and filter element life is short and the replacement cycle is short.Based on this, we need to consider to improve material and the structure of filter, material should be selected to draw materials extensively and the material of environmental protection, mainly start with from two aspects and optimize improvement filtration, the one, improve the distributing homogeneity of particle in filter core inside, improve the effective filtration area of filter core; The 2nd, the exhaust back pressure of reduction filter, the filter efficiency of raising filter.For making up the deficiency of existing diesel-oil vehicle PM filtrating equipment, we are devoted to find that a kind of exhaust back pressure is little, filter efficiency is high, long service life, cost are low and the filter of environmental protection, can more effective soot particulate in exhaust gas from diesel vehicle be trapped, realize the value of its economy and environmental protection aspect.
Model utility content
The utility model is mainly for the deficiency of existing diesel PM filtrating equipment, design a kind of diesel-oil vehicle PM filter cleaner with guide vane and gear shape biomass fiber filter core, it comprises the gear shape biomass fiber filter core that filter chamber, blade fair water cone, guide vane, front and back sealing cover, front and rear cover, metal inner support thing, metal are fixed net outward and be made up of several pair of fold; This device material for core is a kind of biomass fiber, draws materials extensively convenient, and cost is low, good filtration effect, and the two fold moulding on its outer wall have not only ensured the stable of structure but also have increased effective filter table area, saved raw material simultaneously; When tail gas is entered after filtrating equipment by suction port, through the water conservancy diversion drag reduction of blade fair water cone, flow along its streamlined outer wall to surrounding, and move towards along guide vane, from impeller clearance by entering filter chamber, in this process, air-flow becomes effluent through guide vane effect from uprush, be that straight line motion becomes circular movement, make tail gas enter before filter core dispersed, and uniform ring, around distribution, avoids tail gas to stop up in advance or make filter element filtering Efficiency Decreasing by causing in a large number from a filter core part always on the effective filtration area of filter core; Tail gas after dispersed enters its internal cavities by the outer surface of gear shape filter core, and then obtains adsorption filtration, and discharges clean tail gas by air outlet.
This device filter efficiency is high, and filter core is fully utilized, long service life, and the replacement cycle is long, and cost is lower, environmental protection, technique is simple, can effectively reduce the discharge of diesel-oil vehicle particulate matter.
Brief description of the drawings
Fig. 1 is a kind of filter structure schematic diagram of the novel biomass fiber PM filter cleaner with guide vane, 1 front sealing cover, 2 rear sealing covers, 3 front-end faces, 4 ear end faces, 5 wire netting inner frames, the outer skeleton of 6 wire nettings, 7 filter cores
Fig. 2 is a kind of filter chamber's structural representation of the novel biomass fiber PM filter cleaner with guide vane, 8 blade fair water cones, 9 guide vanes, 10 filter chambers, 11 suction ports, 12 air outlets
Embodiment:
Wire netting is made to the outer skeleton of gear shape and the inner frame cylindraceous with two folds.The biological material such as timber, bamboo wood is cut to biomass fiber thick into about 0.05-1mm, that 0.5-5mm is wide, 20-50mm is long and it is heat-treated, then the biomass fiber preparing is mixed with glass fibre, and add resin agitating even, packed into inside and outside the tubular of wire netting in the middle of skeleton, it is dried to preparation.By cemented together with heat-resistant adhesive to the filter core preparing and front and back sealing cover and front/rear end, front sealing cover end puts guide vane, and guide vane upper-end surface installs taper blade fair water cone additional.
Filter is placed in to filtering cavity, blade water conservancy diversion hat brim edge is nested on filtering cavity inwall just.Ensureing under filter and the coaxial prerequisite of filtering cavity, making upper end, the air outlet sealing joint of sealing cover and filter after filter.The filtering cavity that filter has been installed is placed in to exhausting pipe of diesel oil vehicle rear, and tail gas, through the water conservancy diversion rectification of blade fair water cone and guide vane, flows into internal cavities by filter core gear shape outer surface, finally flows out from air outlet.In this process, tail gas is fully filtered by gear shape filter core, thereby gives off clean tail gas.
Claims (4)
1. with a novel biomass fiber PM filter cleaner for guide vane, it is characterized in that: filter chamber is made up of blade fair water cone, guide vane and filter chamber; Filter is made up of front and back sealing cover, front and rear cover, inner support thing, outer fixing net and the gear shape biomass fiber filter core that is made up of several pair of fold; Completed rectification before the filter of tail gas by blade fair water cone and guide vane, complete the adsorption filtration to tail gas particle by filter core.
