Description
Technical field
The utility model is specifically related to a kind of DPF carrier regeneration regenerated offline device of DPF carrier regeneration regenerated offline technology, particularly diesel engine particle catcher regenerated offline.
Background technique
Along with the development speed of automotive industry is more and more faster, the pollution of motor exhaust to air is also more and more serious, to the requirement increasingly stringent of automobile exhaust emission standard in national environmental protection regulation, independent dependence emission controls by improving combustion technology has been difficult to satisfy regulatory requirement, and this just needs the emission aftertreatment technology constantly improving vehicle exhaust.
The pollution of atmosphere of current China is serious, and haze weather appears in large size, and air quality is poor, and one of the main reasons is wherein the tail gas pollution of diesel-oil vehicle.DPF is widely used as the product removing black smoke in diesel engine vent gas, and belongs to the starting stage in China.DPF product is because the physics interception black smoke adopted, and long-time use will cause and the blocking of DPF carrier, and the method for regeneration has multiple, and wherein a kind of method is efficiently regenerated offline technology.This regenerated offline technology needs to consider the influence factors such as fuel injection quantity, regeneration temperature, recovery time, ventilation.
Summary of the invention
For the problems referred to above, the technical problems to be solved in the utility model be to provide one can make the highly efficient regeneration of DPF carrier off-line, recovery time short, regenerate DPF carrier regeneration regenerated offline device thoroughly.
DPF carrier regeneration regenerated offline device of the present utility model, comprises regenerated offline Setup Controller and firing chamber; Described firing chamber is connected with carrier and outlet pipe in turn; Described regenerated offline Setup Controller is connected with performance element; Described performance element is connected with firing chamber with ignition mechanism respectively by injection system, blower fan; Described carrier two ends are provided with temperature transducer and differential pressure pickup; Described temperature transducer and differential pressure pickup are all connected with regenerated offline Setup Controller; Described temperature transducer and differential pressure pickup are also connected with monitoring record unit; Described firing chamber is also connected with cooling fan.
The utility model beneficial effect: one of the present utility model can make the highly efficient regeneration of DPF carrier off-line, recovery time short, regenerate DPF carrier regeneration regenerated offline device thoroughly and have the following advantages:
1, can accurate measurement fuel injection amount: carrier pressure difference signal is passed to regenerated offline Setup Controller by the differential pressure pickup on this device, bed temperature signal is passed to regenerated offline Setup Controller by temperature transducer, regenerated offline Setup Controller, according to pressure difference signal and temperature signal, realizes the fuel injection amount under different operating mode by change dutyfactor value.
2, the recovery time is short, and regeneration efficiency is high: according to pressure reduction and the temperature of carrier, accurately controls the fuel injection quantity of injection system, ensures combustion temperature, is fallen by the carbon-smoke combustion of interception the most fast, reduces the recovery time, improves regeneration efficiency.
Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is system block diagram of the present utility model.
Embodiment
DPF carrier regeneration regenerated offline device as shown in Figure 1, comprises regenerated offline Setup Controller 1 and firing chamber 2; Described firing chamber 2 is connected with carrier 3 and outlet pipe 4 in turn; Described regenerated offline Setup Controller 1 is connected with performance element 5; Described performance element 5 is connected with firing chamber 2 with ignition mechanism 8 respectively by injection system 6, blower fan 7; Described carrier 3 two ends are provided with temperature transducer 9 and differential pressure pickup 10; Described temperature transducer 9 is all connected with regenerated offline Setup Controller 1 with differential pressure pickup 10; Described temperature transducer 9 and differential pressure pickup 10 are also connected with monitoring record unit 11; Described firing chamber 2 is also connected with cooling fan 12.
The utility model provides high temperature to be burnt by the carbon black be attached on DPF carrier by firing chamber.In order to ensure the thoroughly efficient of regeneration, the utility model has added differential pressure pickup and temperature transducer at carrier two ends.Differential pressure pickup is for measuring the pressure reduction at carrier two ends, judge that whether the regeneration of carrier is thorough, temperature transducer is for judging when regeneration starts when to terminate and regenerate to be in what state, and pressure difference signal and temperature signal are passed to regenerated offline Setup Controller, after regenerated offline Setup Controller carries out decision-making, by signal transmission to performance element, performance element controls injection system, blower fan and ignition mechanism and carries out work, again pressure difference signal and temperature signal are fed back to regenerated offline Setup Controller, form a complete closed loop control system.Monitoring record unit is used for record regenerating data, and display regeneration event and temperature, pressure reduction etc., monitor in real time to regenerative process.Cooling fan cools control system, the good operation of Guarantee control system.
Embodiment recited above is described preferred implementation of the present utility model, not limits design of the present utility model and scope.Under the prerequisite not departing from the utility model design concept; the various modification that related domain ordinary person makes the technical solution of the utility model and improvement; protection domain of the present utility model all should be dropped into; the technology contents of the utility model request protection, all records in detail in the claims.
