Description
Technical field
This utility model relates to the tail gas disposal technique field of electromotor, particularly to air-flow uniform device and the purifier of engine tail gas purification.
Background technology
Engine tail gas purifier soot particle in use for some time results in blockage in being accumulated in depurator filtration channel, and therefore increases Diesel engine back pressure, reduces performance, so needing to regenerate polishing filter.
Traditional regeneration is mainly fuel heater and electric heater.
Chinese patent application CN 103502589 A, discloses the exhaust gas treatment device of a kind of electromotor, and this device can make the PM accumulating in DPF burning or can activate exhaust emission control catalyst after electromotor just starts or during light load operation.But still there is following deficiency: it is many to there is local gas in waste gas inflow intensification chamber, and other side gas is few；Local gas flow velocity is fast, and gas flowing is uneven, can affect the uniform diffusion of intensification intracavity pressure high temperature hot gas；Cause the particulate matter cleaning in PDF the most complete.
Utility model content
The purpose of this utility model is to provide the air-flow uniform device of engine tail gas purification, makes intensification intracavity pressure high temperature hot gas uniformly spread to the inner chamber of DPF along its wall, is cleaned out by the particulate matter in PDF.
Above-mentioned technical purpose of the present utility model has the technical scheme that the air-flow uniform device of engine tail gas purification, it is characterized in that, including with the breather in uniform chamber and be located at the uniform dish at the port of export in described uniform chamber；The gas outer wall by the shunting of described uniform dish and along uniform dish uniformly spreads to surrounding.
Using the technical program, waste gas mixed high-voltage high-temperature gas flows to uniform dish by the port of export in uniform chamber；Mixed gas flows slowly through uniform dish, shunts and spreads towards periphery along the appearance of uniform dish, makes the uniform inner chamber that must flow to DPF of mixed gas；Will be attached to the burning particulate matter on internal chamber wall clean.
Arranging further, the shape of cross section of described uniform dish is isosceles triangle；It is 137 degree of-142 degree that this isosceles triangle is made up of the number of degrees of angle two waist edge.
If the angle too small of angle, uniformly folding less than unhurried current, the effect of shunting, mixed gas is disperseed or uneven；If the angle of angle is excessive, exhaust back pressure can be increased, be unfavorable for that waste gas is discharged, also increase the loss of electromotor simultaneously.
In the range of the number of degrees of angle are spent at 137 degree-142, mixed gas is uniformly dispersed, and exhaust back pressure also will not be caused to increase simultaneously.
Arranging further, the number of degrees of the angle that this isosceles triangle is made up of two waist edge are 140 degree.
The number of degrees of angle, at 140 degree, are optimum angle angle value；Through test determination: actual reproduction rate can reach more than 98%.
Arrange further, also include that the sleeve pipe with hybrid chamber and its shape of cross section are isosceles trapezoid；Described sleeve pipe is connected with the entrance point of breather.
Being arranged such, hybrid chamber has bigbore air inlet and small-bore gas outlet；Waste gas and high temperature and high pressure gas successively in air inlet, gas outlet mixing, flow into uniform chamber through twice mix homogeneously again.
Arrange further, be outward extended with connecting rod from the port of export of breather；Described uniform dish is fixed on connecting rod.
Another object of the present utility model proposes a kind of Tailgas purifier of engine, it is characterized in that, including being provided with the installation cavity of said flow uniform device, the intensification chamber being arranged at installation cavity one end and the working chamber arranging with intensification cavity dumping and being connected；It is provided with in described working chamber and liquid diesel is changed into the fuel conversion equipment of steam state diesel oil and is used for lighter diesel oil ignited for steam state.
The effect of air-flow uniform device is to make the uniform inner chamber that must flow to DPF of mixed gas；Will be attached to the burning particulate matter on internal chamber wall clean, actual reproduction rate can reach more than 98%.
Arranging further, it is 45 degree that intensification chamber is connected the number of degrees of the angle combining formation with working chamber.
Being arranged such, the fuel mechanism in working chamber is positioned at the outside of motor exhaust exhaustor；Reduce the exhaust resistance of electromotor.
Arrange further, also include the pressure detecting exhaustor connected with installation cavity；Described pressure detecting exhaustor includes the spire making gas spiral flow and the straight-through flexible pipe being connected with spire.
Outside pressure detector is by the air pressure within pressure detecting aerofluxus tube detection device；If the air pressure of inside arrives setting value, then it can send the signal of the particulate matter on the internal chamber wall of cleaning DPF；But during existing detection, mixed gas contains particulate matter and passes through pressure detecting exhaustor, and after long-time use, particulate matter can be attached at the tube wall of pressure detecting exhaustor and the entrance point of pressure detector, even build-up of pressure detection exhaustor blocking；Affect the accurate mensuration of pressure detector；If pressure detector can not be accurately detected the actual air force value of inside, then regenerative system delays to open, thus causes the exhaust back pressure of engine interior to increase, and affects the performance of electromotor.
This pressure detecting exhaustor is provided with spire, spire that is one section serpentine pipe.Mixed gas is passed through and can rotate with serpentine pipe；Particulate matter in mixed gas can be deposited on the bottom of serpentine pipe because of self gravitation, and passes through the mixed gas of " filtration " by straight-through flexible pipe feed pressure detector.Therefore, this pressure detector can be accurately detected actual pressure value, and regenerative system can be opened in setting value, the particulate matter on the internal chamber wall of cleaning DPF.
Arranging further, be provided with burning protection sleeve pipe in described working chamber, described fuel conversion equipment at least oil spout end is positioned at burning protection inside pipe casing.
The heat that the effect of burning protection sleeve pipe produces when being to assemble high pressure steam state diesel combustion, improves combustion stability；Alternatively, it is also possible to avoid the interference to lighter ignition operation of tail gas that electromotor gets rid of.
Arrange further, also include the flow-stopping plate being located at burning protection cannula end.
The effect of flow-stopping plate is preferably to avoid the impact to working chamber of the front end motor exhaust, thus causes bad effect.
In sum, this utility model has the advantages that the stable performance of this purifier, and pressure high temperature hot gas is with waste gas good mixing effect, diffusion uniformly；Meanwhile, pressure detector detection is accurately, it is possible in correct time, stable being cleaned out by the particulate matter in particle trap.
