In diesel engine vent gas, contain the particulate matters such as a large amount of cigarette carbon, these particulate matters are commonly called as PM.These particulate matters are directly discharged in air can cause serious pollution.
The pollution producing for reducing these particulate matters adopts particle trapper to trap it at present in vehicle exhaust is processed.The wall of this particle trapper is to be made by porous ceramics; an outlet of two passages that porous ceramics is adjacent is blocked; the entrance of another passage is blocked; exhaust enters from the entrance of a passage; enter adjacent access portal through ceramic wall, therefore particle is trapped within on ceramic wall, but along with the smokeshade on ceramic wall constantly assemble and can not get removing; can have influence on the normal ventilation volume of diesel engine, increase the energy consumption of diesel engine.The particulate matter of removing on ceramic wall at present mainly contains two kinds of methods: the one, and the method for initiative regeneration, be reach regeneration point particle trapper work a period of time after, make cigarette carbon burning by modes such as electric heating, microwave heating or burner heating, thereby eliminate particulate; The 2nd, the method for passive regeneration,, by the point of ignition of Catalysts for Reducing cigarette carbon microsphere, utilizes the waste heat of tail gas to make cigarette carbon burning.For these two kinds of particle trapper regeneration method part that comes with some shortcomings: the problem such as the method for initiative regeneration exists that supplementary equipment is many, system complex, bulky and reliability are poor, need to fill spray fuel combustion supporting simultaneously, increase the consumption of fuel; And the method for passive regeneration is high to the quality requirements of fuel, the elements such as the sulphur, phosphorus and the heavy metal that exist in diesel oil easily make catalyst poisoning, cause catalyst failure.
Summary of the invention:
The purpose of this utility model is to solve prior art deficiency, provides a kind of simple in structure, the Fractions of Diesel Engine Exhaust Particulates purification plant of energy-saving safe, good purification.
Fractions of Diesel Engine Exhaust Particulates purification plant of the present utility model, comprise cylindrical shell, outlet pipe, diesel engine, power supply unit and detection device, in described cylindrical shell, be provided with wall-flow ceramic filter, described wall-flow ceramic filter two ends are provided with resistance heater, described resistance heater is connected by switch with described power supply unit, described cylindrical shell one end is provided with suction port, the described cylindrical shell the other end is provided with air outlet, between described suction port and described resistance heater, be provided with temperature transducer, described suction port is connected with described diesel engine, described air outlet is connected with described outlet pipe, described suction port and described air outlet place are separately installed with pressure transducer, described detection device is connected with described pressure transducer, the open and close of switch described in described detection device control.
From such scheme, detect the pressure of suction port and air outlet by pressure transducer, the pressure of suction port and air outlet is reached to detection device, by the analysis comparison of detection device, if detect that the pressure difference of suction port and air outlet is more than or equal to default pressure difference, control switch closure so, at this moment power supply unit and resistance heater are connected, resistance heater can heat the particulate sticking in wall-flow ceramic filter, make particulate reach point of ignition, in wall-flow ceramic filter particle burning to a certain extent after, the pressure difference of suction port and air outlet will reduce, when being reduced to while being less than default pressure difference, detection device is by switch opens.Fractions of Diesel Engine Exhaust Particulates purification plant can constantly recycle, and has extended its working life.
A preferred version is that described power supply unit comprises solar module and electric accumulator, and described solar module is electrically connected with described electric accumulator.
From such scheme, because power supply unit comprises solar module, can utilize the electricity generate function of solar module, Fractions of Diesel Engine Exhaust Particulates purification plant is powered, simultaneously by unnecessary power storage in electric accumulator, energy-conserving and environment-protective.
A preferred version is that described solar module is double-side silicon-glass solar cell.
Comprehensive such scheme is known, and Fractions of Diesel Engine Exhaust Particulates purification plant of the present utility model has long service life, the advantage of energy-conserving and environment-protective.
Brief description of the drawings:
Fig. 1 is schematic diagram of the present utility model.
Identifier declaration in figure: suction port 1, pressure transducer 2, detection device 3, cylindrical shell 4, temperature transducer 5, resistance heater 6, wall-flow ceramic filter 7, power supply unit 8, electric accumulator 81, solar module 82, diesel engine 11, outlet pipe 12, switch 13.
Embodiment:
For setting forth thought of the present utility model and object, below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, Fractions of Diesel Engine Exhaust Particulates purification plant of the present utility model, comprise cylindrical shell 4, outlet pipe 12, diesel engine 11, power supply unit 8 and detection device 3, in cylindrical shell 4, be provided with wall-flow ceramic filter 7, wall-flow ceramic filter 7 two ends are provided with resistance heater 6, resistance heater 6 is connected by switch 13 with power supply unit 8, cylindrical shell 4 one end are provided with suction port 1 and air outlet 10, between suction port 10 and resistance heater 6, be provided with temperature transducer 5, temperature transducer 5 is for measuring the temperature between suction port 10 and resistance heater 6, suction port 1 is connected with diesel engine 11, air outlet 10 is connected with outlet pipe 12, suction port 1 is separately installed with pressure transducer 2 with 10 places, air outlet, detection device 3 is connected with pressure transducer 2, the open and close of detection device 3 control switchs 13.Power supply unit 8 comprises solar module 82 and electric accumulator 81, and solar module 82 is electrically connected with electric accumulator 81.Solar module 82 comprises double-side silicon-glass solar cell.Can utilize the electricity generate function of solar module 82, Fractions of Diesel Engine Exhaust Particulates purification plant is powered, simultaneously by unnecessary power storage in electric accumulator 81.
