Embodiment
Further specify particular content of the present invention below in conjunction with the accompanying drawing illustrated embodiment.
Figure 1 shows that square classified filtering, detachably, monomer structure schematic representation from car periodic regeneration diesel particulate filter, the tail gas of diesel engine enters particle trapper from inlet, filter core 6 filters and captures the particulate in the tail gas, filler 5 are used to prevent the leakage of tail gas, can start simultaneously the effect of damping, in the installation process housing middle part pressing plate 4 is taked the locking measure of pretension, can avoid between pressing plate and filler because of the bad leakage phenomenon that exists of fitting, prevent that by locating face 3 tail gas that the play because of filter core 6 causes from revealing on the housing, pressure transducer 1 is gathered catcher and is gone into, the pressure in outlet port points out the driver that filter core 6 is carried out regular regeneration and replacing on display unit 9 by control unit 8.
The dismounting of square detachable particle trapper and install very convenient, housing middle part pressing plate 4 increases pretightening force with bolt 7 in installation process, additional simultaneously locking measure, avoid the accidental of housing middle part pressing plate 4 in car running process, make also simultaneously that installation, the dismounting of pressing plate are simpler, after housing middle part pressing plate 4 unloaded, the filter core 6 of particle trapper can take out easily.
What Fig. 3 showed is the hierarchy of square detachable particle trapper, the square particle trapper of its method of operation and single step arrangement is roughly the same, in the structure of multistage square removable particle trapper, the mounting type of pressure transducer is divided into two kinds: a kind of is only at the entrance and exit of the particle trapper of multilevel hierarchy two pressure transducers to be installed, this mode technology is simple, cost is low, but can only monitor the overall operation situation of multistage particle trapper, can not detect working condition the particle trapper of each grade; Another kind is that pressure transducer is all installed in the inlet and the outlet of each grade particle trapper in multilevel hierarchy additional, though it is higher to do cost like this, can detect the working condition of each grade particle trapper effectively, in time feeds back corresponding information.
What Fig. 2 showed is circular detachable particle trapper, and the shape of circular detachable particle trapper is identical with traditional particle trapper, and its method of operation is identical with the square particle trapper that Fig. 1 shows.The tail gas of diesel engine enters particle trapper from the ingress, the pressure transducer 1 of particle trapper changes into electrical signal with the pressure of tail gas in the ingress and is transferred to control unit 8, the filter core 6 of particle trapper plays a part to filter particulate in the motor exhaust, for preventing that tail gas from leaking, filler 5 in the particle trapper have played the effect of good sealing, because particle trapper has increased pretension and has loosened measure in installation process, fit between the middle piece housing of meagre profit catcher and the filler 5 and well do not have the leakage possibility, leave locating face 3 in the housing of particle trapper and prevent that the tail gas that causes because of filter core 6 plaies from revealing, the pressure transducer 1 in outlet port changes into electrical signal with the pressure of tail gas in the outlet port and imports control unit 8 into, control unit 8 calculates the pressure loss at filter core two ends in conjunction with the database of self storing according to the electrical signal of two pressure transducer inputs, the pressure loss according to the particle trapper two ends draws the deposition that is deposited on particulate on the filter core simultaneously, determine the particulate clogged conditions of filter core according to different depositions, estimate the regeneration period in conjunction with the database that has existed in the control unit simultaneously, and the conclusion that draws is transferred to display equipment 9, the main effect of display unit 9 is that the signal of indicative control unit 8 outputs provides particle trapper definite working state for the driver, the driver can be well understood to the regeneration period of the particle trapper of the clogged conditions of filter core 6 in the particle trapper and expectation by display unit, reminds the driver in time filter core to be maintained and safeguards.
Because the relation of shape, the housing of circular removable particle trapper can be divided into: three parts in stage casing and two ends, the dismounting of particle trapper need loose ends and stage casing to the bolt of connection and the locking gear that adds.The location of filter core can apply pretightening force by two ends and filter core is compressed prevent its axial float, and the radial-play of filter core, buffering and sealing realize by filler 5.
What Fig. 4 showed is the multilevel hierarchy of circular removable particle trapper, and its working method and square removable particle trapper are basic identical, and the installation of its pressure transducer also exists dual mode.Its dismounting and mounting type are identical with the single step arrangement of circular removable particle trapper.
The removable particle trapper of burst that Fig. 5 shows, each sheet filter core pore size difference, the aperture that begins the particle trapper filter core from the gas inlet end is descending, realizes the multipolarization of particle trapper in the housing of a particle trapper.In the process that particle trapper purifies tail gas, this structure decrease the pressure loss of tail gas in catcher, reduced the exhaust back pressure of motor, the power of motor is improved; In regenerative process, because the filter core axial dimension of split blade type particle trapper is little, its regeneration effect is obvious, and regeneration thoroughly.
The running of the removable particle trapper of burst is, the tail gas of diesel engine enters particle trapper from the ingress, the pressure transducer 1 of particle trapper changes into electrical signal with the pressure of tail gas in the ingress and is transferred to control unit, the filter core 6 of particle trapper plays a part to filter particulate in the motor exhaust, because the aperture difference of filter core, the diameter of the particulate of every grade of filter core capture also is not quite similar, aperture maximum at the entry end filter core of tail gas can be missed the less particulate of diameter, this filter core is to capture the bigger particulate of diameter specially, the aperture of second filter core is smaller than first, capture a little bit smaller slightly particulate of diameter, successively decrease step by step in later filter core aperture, the diameter of the particulate that captures also makes more and more littler, can reduce diesel particulate emission effectively like this, also avoided simultaneously piling up the short problem of particle trapper life cycle that causes mutually because of the particulate of various diameters, for preventing that tail gas from leaking, pad 5 in the particle trapper has played the effect of good sealing, because the location pit of particle trapper is cast directly on the housing 2 of particle trapper, filter core 6 is played sealing, the filler 3 of buffering and fixation are directly inserted in the pit of location, filler compressed filter core 6 when housing was installed, filter core has been played the effect of location, axial and the activity surplus radially of restriction filter core, prevent effectively that simultaneously the tail gas that causes because of filter core 6 plaies from revealing, the pressure transducer 1 in outlet port changes into electrical signal with the pressure of tail gas in the outlet port and imports control unit into, control unit calculates the pressure loss at filter core two ends in conjunction with the database of self storing according to the electrical signal of two pressure transducer inputs, the pressure loss according to the particle trapper two ends draws the deposition that is deposited on particulate on the filter core simultaneously, determine the particulate clogged conditions of filter core according to different depositions, estimate the regeneration period in conjunction with the database that has existed in the control unit simultaneously, and the conclusion that draws is transferred to display equipment, the main effect of display unit is that the signal of indicative control unit output provides particle trapper definite working state for the driver, the driver can be well understood to the regeneration period of the particle trapper of the clogged conditions of filter core in the particle trapper and expectation by display unit, reminds the driver in time filter core to be maintained and safeguards.
The installation and removal side of being different from of the removable particle trapper of burst/circular removable particle trapper, the housing of the removable particle trapper of burst is divided into upper and lower two parts, two housing sections links together by bolt and the loosening mechanism that has more, bolt increases pretightening force in installation process, whole particle trapper has been played the effect of sealing.In the unloading process of particle trapper, the side of being different from/circular removable particle trapper need to disconnect and to be connected to such an extent that flange bolt just can unload particle trapper and maintains and safeguard under particle trapper and the engine exhaust pipe.
