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 dirt outlet pipe that disappears is the ground connection erecting device, and the cathode bar 2 of planting in outlet pipe 1 is fixedly installed in cathode bar 2 supporting frame 6 of high temperature resistance, insulation to guarantee that cathode bar 2 does not contact with outlet pipe 1.Because motor-driven vehicle aerated particle dust mainly is made up of imperfect combustion carbon particle in the oil gas, have high temperature, high humidity, short grained characteristics, be suitable for ionization absorption, so in motor-vehicle tail-gas of the present invention disappears the high-voltage electrostatic field environment architecture of dirt outlet pipe, the tail gas particle dust that is discharged is charged by cathode bar 2, charged dust 13 is attracted in the zero potential exhaust pipe under the effect of electric field force, makes the tail gas 14 of motor vehicle emission become purified gas 15, reaches the disappear purpose of dirt of tail gas waste gas; Asymmetrical design is adopted at this tail gas cathode bar 2 rear portions that disappear in the dirt outlet pipe simultaneously, makes to be discharged the air-flow granule that swims in outlet pipe top and to obtain better chargedly, obtains better absorption dust effect; And the tail gas that this ground connection the arranges dirt outlet pipe that disappears also will be adsorbed the high temperature, the high humidity negative electricity grit that are discharged from a small quantity by the earth 16, effectively suppress tail gas and discharge dust granules and swim in the air wantonly; The disappear high-voltage electrostatic field of dirt outlet pipe of motor-vehicle tail-gas of the present invention can be adsorbed for a short time of 0.01 μ m particle, can effectively suppress PM2.5 grit exhaust gas discharging.
As shown in Figure 2, disappear dirt outlet pipe end bottom of this tail gas is provided with a storage dirt device 3, and storage dirt device is a spill supporting plate 4, be provided with in outlet pipe end bottom one with the installation window 5 of spill supporting plate 4 couplings, spill supporting plate 4 detachably is installed on installs window 5.Consider that dust adsorbed is under the gravity effect in the outlet pipe 1; when motor vehicle operation vibrations; outlet pipe 1 bottom section will be deposited on naturally; in the course of time form the dust dust heap; and the oil gas adsorption precipitation in the tail gas also can form clc layer on electric shock baton and in the outlet pipe 1; when reaching certain thickness, clc layer will influence electrostatic field absorption dust removal efficiency; this tail gas dirt outlet pipe that disappears is provided with a storage dirt device 3 in outlet pipe end bottom; make and when vehicle maintenance, be convenient to clean dust; greasy dirt, and set detachable installation window 5 hairbrush class instruments easy to use; detergent carries out maintenance operations such as dedusting scrubbing and replacing cathode bar.
As shown in Figure 3, this tail gas disappears and is provided with high-voltage output circuit 7 in the dirt outlet pipe vent systems, high-voltage output circuit 7 comprises that direct current delivers stream inverter circuit 8 and rectification circuit 9, the input port of inverter circuit is electrically connected with the 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; This tail gas disappears and also comprises CPU master control set 11 in the dirt outlet pipe vent systems, and an end of CPU master control set 11 is connected with vehicle CAN bus 12 signals, and the other end is electrically connected with energy of electric automobile output unit 10.Because Vehicular exhaust smog exhaust gas discharging mainly shows the accelerating process that motor vehicle speed changes, in the climbing process, so adopt the pick-up performance efficient under the constant electrostatic field condition lower, so the design utilizes CPU master control set 11 to be connected with vehicle CAN bus 12 signals, detect engine speed in real time, Vehicle Speed, the perception travel condition of vehicle, and the high-voltage output circuit 7 negative electrode intensity that adjustment in real time is electrically connected with automobile according to travel condition of vehicle, improve or reduce the electrostatic field value, when vehicle is at the uniform velocity state, the control field intensity is the low value point, and toxic emission is more when automobile is climbed or accelerate to advance, corresponding lifting electrostatic field value then, thus reach the purpose of high-effective dust-removing.
As shown in Figure 4, the variation of electrostatic field intensity E increment size in the unit time along with vehicle rotating speed and travelling speed and changing, during the vehicle uniform motion, the field intensity value is minimum.
The above only is the preferred embodiments of the present invention; be not so limit its claim; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; directly or indirectly be used in the automotive engineering field, all in like manner be included in the scope of patent protection of the present invention.
