Abstract

An exhaust gas filter for motor-driven vehicles is composed of gas inlet, gas outlet, casing, exhaust blower and water contained in casing for filtering harmful gas. It can be directly mounted to end of exhaust tube or before the silencer, or combined with three-element catalyzer for elongating service life of catalyzer, improving catalysis effect and increasing quality of exhaust gas.

Description

Exhaust gas filter for motor-driven vehicle

The present invention relates to a kind of motor-vehicle tail-gas filtrating equipment relevant with environmental protection.

Tail gas pollution of motor-driven vehicle day is easily serious, directly jeopardizes the space that the mankind depend on for existence, and the particle that swims in the tail gas contains harmful matters such as soot, leadization thing, is sucked lung by the people and can cause chronic disease, pulmonary emphysema, and carcinogenesis is arranged.Therefore national governments have all formulated relevant policies and are controlled and transform.

The purpose of this invention is to provide a kind of device, the particulate leaching of swimming in the motor-vehicle tail-gas is fallen, alleviate the pollution of tail gas atmosphere.This device and ternary Cuiization device are used in combination the life-span that can prolong ternary Cuiization device, improve Cuiization effect, reduce the excessive phenomenon of resistance that Cuiization device supply and exhaust causes.

For achieving the above object, technological scheme of the present invention is: a kind of exhaust gas filter for motor-driven vehicle has housing, suction tude, steam outlet pipe and induced draft fan and forms.Fill water in the shell.

For harmful gas is fully contacted with water, prolong the water-soluble time of harmful gas.Be equipped with a plurality of apertures in the bottom of suction tude, in housing, be added with filter plate simultaneously.

For the generation that reduces incrustation scale in the housing with help combining of water molecule and harmful matter.Permanent magnet is housed in the housing, makes the water in the shell become magnetized water.

For harmful gas is fully contacted with water, stirrer is equipped with in the bottom of housing.

Further specify the present invention below in conjunction with accompanying drawing and by embodiment:

Fig. 1 is embodiment 1 a structural representation

Fig. 2 is embodiment 2 a structural representation

Fig. 3 is embodiment 3 a structural representation

Embodiment 1: connecting head 1 is used for suction tude 2 and is connected with motor vehicle exhaust.The 3rd, mouth of a river plug is used for the water intake sealing, and the 4th, outlet pipe links to each other with housing 9, and aspirator 5 is housed on the outlet pipe.The 6th, the anti-sealing of manger board is shallow to be gone out, and the 7th, the water level viewing window, the 8th, filter plate is equipped with a plurality of apertures on the filter plate.The 9th, housing, the bottom of suction tude 2 is equipped with a plurality of apertures 10,11st, permanent magnet, the 12nd, bottom.

The working principle of present embodiment is: with the aspirator power supply opening, aspirator is taken out at the district A in the housing and is negative pressure in the time of motor vehicle starting, is connected because the bottom of suction tude 2 has in a plurality of apertures 10 and the housing.When the air pressure in B district was greater than the resistance of water in the suction tude, the gas in B district entered by aperture 10 downwards and upwards enters the A district by filter plate B then in the housing and discharged from outlet pipe by aspirator.Particle in the harmful gas, leadization thing, soot etc. are dissolved in the water, reach to eliminate the purpose that soot reduces the motor-vehicle tail-gas oxious component.When the gas in B district enters in the water in the suction tude 2 is the gross blowhole state, enter by aperture 10 and to become small bubble in the housing, be divided into small bubble again after bubble reconfigures during upwards by filter plate, increased the chance that harmful matter contacts with water in the gas like this, improved filter quality.Owing to air-flow is arranged at underwater exercise, the water in the housing is wavy, and permanent magnet 11 makes water become magnetized water, has reduced the generation of incrustation scale, and the magnetic line of force has been broken the moisture subchain simultaneously, the easier and water affinity of the harmful matter in the gas.When dirt increases in the housing, can open bottom 12 and clear up, open mouth of a river plug 3 after the cleaning and refill clear water.Can react with harmful gas as in water, adding reagent, be converted into innocuous gas, or increase the water solubilization of harmful matter, can make the gas of discharge cleaner.

Embodiment 2: as shown in Figure 2, its structure is substantially the same manner as Example 1.Just add stirrer in the bottom of housing 9, stirrer is made up of agitating plate 20 and permanent magnet 21, motor 23 is arranged below housing, lifting magnet 22 is housed on the motor, several permanent magnets are housed on the lifting magnet, when motor 23 drives lifting magnet 22 rotations, magnet 21 in the shell and agitating plate 20 and then rotate, and make the water in the shell form rotary water current, when gas passes through, harmful matter in the gas is easier to be combined with water, makes the filter better effects if.

Embodiment 3: as shown in Figure 3, connecting head 1 is used for being connected of suction tude 2 and motor vehicle exhaust, and the 3rd, mouth of a river plug seals water intake, the 4th, outlet pipe communicates with A district in the housing, and the 5th, be contained in the aspirator on the outlet pipe, the 9th, housing, the 11st, permanent magnet, the 12nd, bottom can be opened during cleaning.The 13rd, radiator is to be provided with for the gas temperature that prevents to enter housing is too high, the 14th, and filtering screen, 15 and 19 is that their bottom of filter plate has aperture, the 16th, secondary ion generator, the 18th, isolating plate.

The working principle of present embodiment is: the power supply of aspirator 5 is opened simultaneously when motor vehicle starting, the A district is taken out and is negative pressure in the shell, the gas in C district enters in the water downwards, pass from the aperture of filter plate 19 bottoms and upwards to enter the A district again, discharge by outlet pipe, the air pressure in C district reduces, the gas in B district enters in the water downwards, upwards enter the C district again by the aperture under the filter plate 15, owing to be added with isolating plate 18 in the middle of the C district, make harmful gas enter the C district, enter once more and arrive the A district in the water, increased the travel distance of harmful gas in water from the B district, in the present embodiment, have little suction port on the suction tude 2, filtering screen 14 is housed on the little suction port, gas enters from little suction port during very few or not exhaust when engine exhaust, because the B district is a negative pressuren zone always, so do not influence the normal discharging of Motor Vehicle, too fast for the too high water evaporates of temperature that prevents to enter housing, radiator 13 is housed on suction tude 2.For the gas behind the purification filtering, be equipped with at the afterbody of outlet pipe 4 and pay an ion generator, the high-pressure electrostatic that is produced has dustproof effect, pays oxonium ion and ozone purifies air and disinfective action.

This filter can directly be contained in the afterbody of motor vehicle exhaust, also can be contained in the front of silencing apparatus.If be used in combination with ternary Cuiization device, can prolong the working life of ternary Cuiization device, improve Cuiization effect.

This invention can reduce the pollution of vehicle exhaust to atmosphere, helps people's health, and cost is low not fragile, is suitable for popularization, is of great value environment-friendly products, is bound to bring bigger social benefit and economic benefit.
