Abstract

The invention discloses a tail gas purification device for an automobile and relates to improvement of tail gas purification of the automobile. The device is characterized in that a heat radiator is installed between an air inlet pipe and an air exhaust pipe and is a grid-plate type heat radiation structure body, a temperature lowering fan is arranged outside the heat radiator, a temperature sensor is installed on the surface of the heat radiator, the air exhaust pipe is deep into a clean water area in a purification body, screening holes are formed in the air exhaust pipe in the clean water area, active carbon is placed on the upper portion of the clean water area through a partition plate, a filtering net is arranged on the upper portion of the active carbon, and an air exhaust opening is formed in the upper portion of the purification body. The device has the advantages that tail gas of the automobile is filtered through the device and has chemical reaction with water in the device so that tail gas sulfide can turn into acidic water, and the acidic water can be recycled to be reused. PM2.5 solid particulate matter in the tail gas is processed again through the water in the device, the active carbon and the filtering net, harmful substances will be substantially reduced, and gas exhausted out of the exhaust opening is harmless gas basically.

Description

Vehicle tail gas purification device

Technical field

The invention belongs to environmental technology field, relate to a kind of improvement of purifying vehicle exhaust.

Background technique

At present, the gas that fuel-engined vehicle is discharged, although taked the control techniques of many vent gas treatment, but still has hundreds of different compounds, and wherein pollutant has PM2.5 Solid Suspension particulate, carbon monoxide, hydrocarbon, oxynitrides and sulphide.These tail gas are very serious to the Health cost of human body.Sulfur dioxide in tail gas has strong impulse smell.While reaching finite concentration, easily cause acid rain, cause the acidification at soil and water source.In the composition of haze, vehicle exhaust occupies sizable ratio, and therefore, the atmospheric pollution that vehicle exhaust causes is a very important reason.

Summary of the invention

The object of the invention is: a kind of vehicle tail gas purification device is provided, and it can purify vehicle exhaust comparatively up hill and dale.

Technological scheme of the present invention is: in suction tude and outlet pipe interval, radiator is installed, radiator is screen type heat-radiating structure, radiator outside is provided with cooling fan, spreader surface is provided with temperature transducer, outlet pipe is deep into the clean water area in purification body, and the outlet pipe in clean water area has sieve aperture, and top, clean water area is placed with active carbon by dividing plate, be provided with filter screen on active carbon top, be provided with air outlet on purification body top.

On compact car, fan blade is installed in suction tude, be separately installed with fan A and fan B in radiator outside, fan blade coordinates with fan A transmission by belt.

The invention has the beneficial effects as follows: vehicle exhaust is by this device, filter and with device in water chemical reaction.Make tail gas sulphide become acid water, acid water can reclaim and recycle again.PM2.5 Solid Suspension particulate in tail gas, by the water in device, active carbon and filter screen are processed again, will significantly reduce harmful matter, and the gas of discharging from air outlet is innocuous gas substantially.

Brief description of the drawings

Fig. 1 is that large car uses structural drawing of the present invention;

Fig. 2 is that compact car uses structural drawing of the present invention.

Embodiment

Below in conjunction with accompanying drawing, the present invention is described further:

Embodiment 1

As shown in Figure 1, the 1st, suction tude, the 7th, fan B, the 8th, temperature transducer, the 9th, radiator, the 10th, solenoid valve, the 11st, conduit pipe, the 12nd, water tank, the 13rd, level sensor, the 14th, dividing plate, the 15th, filter screen, the 16th, active carbon, the 17th, purifies waste water, the 18th, drain valve, the 19th, outlet pipe, the 21st, purification body, the 22nd, housing, the 23rd, sieve aperture.

The tail gas of full-sized car is introduced into radiator 9 from suction tude 1, because of exhaust temperature higher, directly enter 17 heating evaporations of purifying waste water that can make in purification body 21, cannot purify, therefore need before entering purification body 21, lower the temperature by radiator 9, on radiator 9 surfaces, temperature transducer 8 is installed, in the time that temperature transducer 8 exceedes 85 ° of C, lower the temperature by force by electric control starting fan B additional cooler 9, after flowing into outlet pipe 19, the tail gas of cooling disperses to discharge by the sieve aperture 23 on outlet pipe 19, 17 fully contact with purifying waste water, by harmful matter and some larger particles such as the sulfur dioxide in tail gas, retain and purify waste water in 17, the tail gas of emerging from water passes through 16 layers of active carbons and fibrous filter net 15 again, just filtering PM2.5 Solid Suspension particulate substantially, the gas of discharging from the air outlet 20 of purification body 21 is like this innocuous gas substantially, evaporate when purifying waste water or be lost to while necessarily rolling off the production line, start the solenoid valve 10 of water tank 12 by level sensor 13, to purification body 21 moisturizings, when purifying waste water, 17 use a period of times can discharge by drain valve 18.

Embodiment 2

As shown in Figure 2, the 1st, suction tude, the 2nd, fan blade, the 3rd, belt pulley A, the 4th, belt, the 5th, belt pulley B, the 6th, fan A, the 7th, fan B, the 8th, temperature transducer, the 9th, radiator, the 10th, solenoid valve, the 11st, conduit pipe, the 12nd, water tank, the 13rd, level sensor, the 14th, dividing plate, the 15th, filter screen, the 16th, active carbon, the 17th, purifies waste water, the 18th, drain valve, the 19th, outlet pipe, the 21st, purification body, the 22nd, housing, the 23rd, sieve aperture.

Before the tail gas of compact car enters radiator 9 from suction tude 1, drive fan blade 2 to rotate by tail gas, fan blade 2 drives belt pulley A, belt 4 and belt pulley B to rotate by rotating shaft, belt pulley B drives fan A to rotate, realize radiator 9 is lowered the temperature, if but radiator 9 temperature further raise, temperature transducer 8 is lowered the temperature by force by electric control starting fan B additional cooler 9 again, and other is identical with embodiment 1.
