Embodiment
Describe technological scheme of the present invention in detail below with reference to drawings and the specific embodiments, so as clearer, understand invention essence of the present invention intuitively.
As shown in Figure 1, this motor-vehicle tail-gas dust elimination outlet pipe is ground connection erecting device, a cathode bar 2 of planting in outlet pipe 1, cathode bar 2 is fixedly installed in high temperature resistance, insulation supporting frame 6 to ensure that cathode bar 2 does not contact with outlet pipe 1.Because motor-driven vehicle aerated particle dust is primarily of carbon particle composition imperfect combustion in oil gas, there is high temperature, high humidity, short grained feature, comparatively be suitable for ionization absorption, so in the high-voltage electrostatic field environment architecture of motor-vehicle tail-gas dust elimination outlet pipe of the present invention, the exhaust particulate dust be discharged is charged by cathode bar 2, under the effect of electric field force, charged dust 13 is attracted in zero potential exhaust pipe, makes the tail gas 14 of motor vehicle emission become purified gas 15, reaches the object of tail gas exhaust dust elimination; In this tail gas dust elimination outlet pipe, cathode bar 2 rear portion adopts asymmetrical design simultaneously, makes to be discharged the air-flow granule swimming in outlet pipe upper part and obtains better charged, obtain better absorption dust effect; And the tail gas dust elimination outlet pipe that this ground connection is arranged, the high temperature making to be discharged on a small quantity, high humidity negative electricity grit also will by the earth 16 absorption, effectively suppress tail gas to discharge dust granules wantonly in atmosphere floating; The high-voltage electrostatic field of motor-vehicle tail-gas dust elimination outlet pipe of the present invention can be adsorbed little of 0.01 μm of particle, effectively can suppress the discharge of PM2.5 grit waste gas.
As shown in Figure 2, be provided with a storage dirt device 3 bottom this tail gas dust elimination outlet pipe end, storage dirt device is a spill supporting plate 4, is provided with an installation window 5 mated with spill supporting plate 4 bottom outlet pipe end, and spill supporting plate 4 is detachably installed on installs window 5.Consider the dust of absorption in outlet pipe 1 under gravity, when motor vehicle run vibrations, by natural sediment at outlet pipe 1 bottom section, in the course of time dust dust heap is formed, and the oil gas adsorption precipitation in tail gas also can form clc layer on electric shock baton and in outlet pipe 1, electrostatic field absorption dust removal efficiency will be affected when clc layer reaches certain thickness, this tail gas dust elimination outlet pipe is provided with a storage dirt device 3 bottom outlet pipe end, make to be convenient to when vehicle maintenance clean dust, greasy dirt, and set detachable installation window 5 hairbrush class easy to use instrument, detergent carries out dedusting scrubbing and changes the maintenance operations such as cathode bar.
As shown in Figure 3, high-voltage output circuit 7 is provided with in this tail gas dust elimination outlet pipe vent systems, high-voltage output circuit 7 comprises direct current and delivers stream inverter circuit 8 and rectification circuit 9, the input port of inverter circuit is electrically connected with energy of electric automobile output unit, the output port of inverter circuit is electrically connected with the input port of rectification circuit, and the output port of rectification circuit is electrically connected with cathode bar; The one end also comprising CPU master control set 11, CPU master control set 11 in this tail gas dust elimination outlet pipe vent systems is connected with vehicle CAN bus 12 signal, and the other end is electrically connected with energy of electric automobile output unit 10.Discharge because of Vehicular exhaust smog waste gas is mainly manifested in the accelerating process of motor vehicle speed change, in climbing process, so adopt the pick-up performance efficiency comparison under constant electrostatic field condition low, so the design utilizes CPU master control set 11 to be connected with vehicle CAN bus 12 signal, real-time detection engine speed, Vehicle Speed, perception travel condition of vehicle, and the high-voltage output circuit 7 negative electrode intensity be connected with automobile electric is adjusted in real time according to travel condition of vehicle, improve or reduce electrostatic field value, when vehicle be at the uniform velocity state time, controlling field intensity is low value point, and toxic emission is more when automobile climbing or acceleration are advanced, then corresponding lifting electrostatic field value, thus reach the object of high-effective dust-removing.
As shown in Figure 4, electrostatic field intensity E along with vehicle rotating speed and in the travelling speed unit time increment size change and change, during vehicle uniform motion, field intensity value is minimum.
The foregoing is only the preferred embodiments of the present invention; not thereby its scope of the claims is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; directly or indirectly be used in automotive field, be all in like manner included in scope of patent protection of the present invention.
