Wherein, it comprises a particle collector, a filter pin and a regeneration controller; the front of the collector frame has a support cover dividing the frame into front and back chambers; said filter pin and the heating resistance wire are arranged at the back chamber; the lower part of suppor6t cover has one hole opposite to the inlet tube, while a hole at upper part is connected to the bypass tube; the axle of two ends of baffle plate is rotationally supported inside the axial base hole of support cover that between the upper and lower holes, while the axle that extruding outside the frame is fixed with a gear wheel meshed with the tooth bar of valve rod of gas valve mounted outside the frame; the gas tube is through to the back chamber, while it has a valve; the inlet tube is mounted with a pressure switch electrically connected to the regeneration controller. The invention can treat the tail gas of diesel engine.
Description
Technical field
The present invention relates to a kind of stripping technique, particularly a kind of particulates in exhaust gas from diesel vehicle catcher.
Background technique
Diesel engine limits the factor that it is further used because its good dynamic economics and durability are used widely but diesel particulates causes the pollution of environment to become.For head it off has occurred particle trapper (filter) abroad as far back as the eighties mid-term, particle trapper is very ripe now.Yet when the particulate loading of catcher mouth collection reaches a certain amount of, exhaust resistance is increased, influence the proper functioning of diesel engine, therefore need removing in time, be called the regeneration of particle trapper, this regeneration techniques is still the technical problem that current needs are solved.Application number is that 200310121764.8 patent of invention discloses a kind of diesel engine truck exhaust microparticles collection device, its filter layer is that composition metal base net plate, oxidation catalyzer and regeneration electric heater are formed, and the regeneration catalyzing device is to be coated on the composition metal base net plate by regenerated catalyst to constitute.Be restricted the working life of this catalyst layer.In addition, the patent No. is 00227987.8 utility model patent, and its technological scheme is, is provided with firing unit, pressure transducer and electric controller in the filter regeneration device, and its firing unit is made up of valve, nozzle, electronics electricity firearm and fuel transfer pump and air pump.This reclaimer must be provided with a cover oil supply system in addition, and structure is too numerous and diverse.
Summary of the invention
The technical issues that need to address of the present invention are a kind of particle catcher for diesel engine of design, and it is simple in structure, and cost is low, favorable regeneration effect, and the life-span is long.Technological scheme of the present invention is, a kind of particle catcher for diesel engine, it comprises particle trapper, filter core and regenerating control device, it is characterized in that: the front portion in the catcher housing is provided with one lid housing is divided into two chambeies, front and back, above-mentioned filter core and resistive heater are located in the back cavity, it is relative with suction tude that a hole is opened in the bottom of lid, top is opened a hole and is communicated with by-pass pipe, the axle rotational support at baffle plate two ends is last, in the axle bed hole that covers between the following hole, the tooth bar of wherein stretching on the valve rod of the pneumatic valve outside fixing a gear and being located at housing on the axle outside housing is meshed, blowdown pipe is communicated with above-mentioned back cavity, which is provided with valve, suction tude is provided with pressure and spreads to close and be electrically connected with regenerating control device.The present invention has been owing to adopted ceramic fiber to twine filter core and slat belt Bypass Control mechanism, thus the present invention have compared with the prior art simple in structure, cost is low, the remarkable advantage of favorable regeneration effect, long service life.
Description of drawings
Fig. 1 is a plan view of the present invention, Fig. 2 be the A of Fig. 1 to view, Fig. 3 be the B of Fig. 1 to partial view, Fig. 4 is the C-C sectional view of Fig. 2.
Embodiment
The invention will be further described in conjunction with above-mentioned accompanying drawing, it is that propping up of 120 degree covers 13 that front portion in housing 1 is provided with an angle, be fixed with the filter core 11 of the ceramic fiber yarn winding of three 120 ° of distributions each other at the rear portion of this lid, between filter core, be evenly equipped with three resistive heaters 12, it is relative with suction tude 5 to have a hole on the vertical plate of lid, the hole of propping up on the swash plate that covers is communicated with housing by-pass pipe 9 outward, and the other end of this by-pass pipe is communicated with the steam outlet pipe 10 of housing 1 rear end.Be provided with pressure switch 6 on suction tude 5, blowdown pipe 8 is connected with the regeneration chamber that a lid and housing rear portion surround.Slat belt Bypass Control mechanism is, baffle plate 14 two ends are fixed with axle and are rotatably assorted in a supported hole that covers, the tooth bar of stretching on pneumatic valve 2 valve rods outside fixing a gear 4 and be located at housing on the axle outside housing 3 is meshed, blowdown pipe 8 is provided with solenoid valve, in suction tude 5, be provided with pressure switch, when filter core stops up when serious, when making the pipeline back pressure be increased to setting value (20kpa), pressure switch 6 engage lights, remind the action of driver control pneumatic valve, rotate by gear driven baffle plate 14 and to close the filter core pipeline and open and be close to road pipe 9, press button simultaneously and make resistive heater 12 energisings, solenoid valve on the blowdown pipe 8 is opened to regeneration chamber tonifying Qi, and when being heated to temperature, the particle burning of filter core becomes carbon granules and breaks away from filter core, general heating need were promptly finished regeneration in about one minute, press above-mentioned button and make the resistance wire outage, closed electromagnetic valve, baffle plate resets, and tail gas is by the filter core proper functioning.This regenerative process also can be controlled automatically.Its signal realizes opening automatically bypass conduit (and closing the filter core pipeline simultaneously) through electronic control unit 7, and resistive heater 12 is lighted and tonifying Qi, finishes the function of regeneration.
