A pressure sensor and a referential pressure pipe are arranged on the air inlet pipe. A combustion-supporting gas pipe for conveying combustion-supporting gas is arranged between the sub-air-inlet pipes and situated behind the dish valve of the sub-purifiers. The purifier is advantageous in that a determination of regeneration points is conducted based on reference, which eliminates error due to different working conditions, models, wearing degrees of different diesel engines and ensure accurate determination of regeneration points; on-site debugging is convenient; combustion-supporting gas for burning particles during regeneration is tail gas of the diesel engine, which neither lowers the pressure of vehicle compressed air nor affects driving safety.
Description
Technical field
A kind of diesel engine vent gas particulate burning purifying device
,Through ceramic for filtration the particle in the diesel engine automobile tail gas is filtered, with electric heater the particle in the pottery is heated during regeneration, utilize diesel engine vent gas combustion-supporting.
Background technique
Existing technology generally adopts wall-flow ceramic filter to catch to the particle of exhaust emissions of diesel engine; When the particle in the porcelain filter runs up to when a certain amount of; When promptly arriving regenerating point, porcelain filter is regenerated, through heating, burning clearance of particles so that filter once more.Existing technology to the judgement of regenerating point through the back pressure of diesel engine speed, diesel exhaust gas pipe end and the measurement of delivery temperature are calculated then; Because the abrasion condition of the operating mode and diesel engine self of diesel engine is different; Different diesel engines there is error according to the regenerating point that same formula calculates with actual regenerating point; After need testing repeatedly diesel engine runnability, modified computing formulae is debugged very inconvenient again; Air required when in addition the particle in the porcelain filter being burnt is provided by vehicle-mounted air compressor, because required air quantity is big, causes vehicle-mounted compressed-air actuated pressure to descend easily, influences traffic safety.
Summary of the invention
Propose a kind of diesel engine vent gas particulate burning purifying device to existing technology deficiency the utility model, the technical problem that the utility model will solve is: get rid of the regenerating point error of calculations that factors such as operating mode because of diesel engine, wearing and tearing are brought, convenient debugging; When the particle in the porcelain filter is burnt, avoid the use of vehicle-mounted pressurized air in addition, prevent compressed air pressure decline and influence traffic safety.
Described diesel engine vent gas particulate burning purifying device comprises the suction tude 01 that connects the exhaust emissions of diesel engine pipe; Be connected the cover of two on the suction tude 01 and divide purifier 101,102; Divide purifier 101 to comprise housing 81,82, be provided with branched inlet pipe 31,32, be provided with outlet pipe 91,92 at the other end of housing at an end of housing 81,82; On the described branched inlet pipe 31,32 dish valve 41,42 is housed; Porcelain filter 71,72 is housed in the housing, electric heater 61,62 is housed in the front of porcelain filter, be provided with the temperature transducer 51,52 of measuring heating-up temperature in the front of electric heater; It is characterized in that: on suction tude 01, also be provided with pressure transducer 02 and pressure reference pipe 03, on pressure reference pipe, solenoid valve 04 be housed; At branched inlet pipe 31, be provided with the combustion-supporting tracheae 05 of carrying combustion-supporting gas between 32, solenoid valve 06 is housed on the combustion-supporting tracheae, combustion-supporting tracheae is positioned at the back of dish valve 41,42.
The pressure that the pressure that under stable diesel engine condition, forms on the described pressure reference pipe forms when falling and reaching regenerating point with ceramic for filtration falls and equates or become a proportionate relationship.
Combustion-supporting gas is a diesel engine vent gas in the described combustion-supporting tracheae.
The power supply that described electric heater uses is vehicle power.
The method for controlling reproduction of described diesel engine vent gas particulate burning purifying device is:
A, under the stable situation of diesel engine condition; Diesel engine vent gas is only discharged through a ceramic for filtration; Measure the pressure on this ceramic for filtration, make diesel engine vent gas only discharge the pressure on the measuring pressure reference pipe then through pressure reference pipe; If the pressure of this ceramic for filtration is less than the pressure on the pressure reference pipe, then at a distance from time of 3 to 5 minutes both pressure of duplicate measurements again; If the pressure of ceramic for filtration more than or equal to the pressure on the pressure reference pipe, shows that then ceramic for filtration reaches regenerating point;
B, when this ceramic for filtration reaches regenerating point, make diesel engine vent gas through this pottery, to this ceramic for filtration heating; Diesel engine vent gas is discharged through another ceramic for filtration; In being heated to ceramic for filtration, during the initiation temperature of particle, stop heating, it is combustion-supporting to open combustion-supporting tracheae; The combustion-supporting time is 10 to 15 minutes, closes combustion-supporting tracheae then.
The beneficial effect that the technological scheme of this aspect compared with prior art has is: 1, the judgement of regenerating point is carried out through the method for reference; Pressure falls and equates when one pressure reference pipe promptly being set its pressure that under identical diesel engine condition, forms being fallen reach regenerating point with ceramic for filtration; Through replacing the pressure of measurement and comparative pressure reference pipe and ceramic for filtration; Can offset the error that diesel engine condition difference, model are different, the equal factor of the degree of wear is brought; The regenerating point accuracy of judgement, field adjustable is convenient.The required combustion-supporting gas of particle burning comes the tail gas to diesel emission when 2, regenerating, and does not use vehicle-mounted pressurized air, can not cause compressed-air actuated pressure decline and influence traffic safety.
