Description of drawings
The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of first embodiment of engine exhaust cleaning device of the present invention;
Fig. 2 is the schematic diagram of second embodiment of engine exhaust cleaning device of the present invention.
The specific embodiment
As shown in Figure 1, the first embodiment of the present invention is applicable to dilly, and wherein engine exhaust cleaning device 100 comprises cleaning waste gas drum 1, is connected cooling water tank 2 that cleans waste gas drum 1 top and the storage tank 3 that is connected by filter 5 and cleaning waste gas drum 1 below.The inlet that cleans waste gas drum 1 is connected with the outlet of the exhaust pipe of vehicle, and the waste gas that engine is produced enters; Its outlet is used for discharging waste gas.Storage tank 3 is connected with cooling water tank 2 by the electric pump 4 that draws water, and the operating voltage of the electric pump 4 that draws water is 12V-24V, is used for the water in the storage tank 3 is drawn into cooling water tank 2, enters after the heat radiation cooling and cleans waste gas drum 1.Clean waste gas drum 1 and link to each other, move the water to flow into filter 5 and filter with filter 5.Filter 5 is connected with storage tank 3, water after the filtration is flowed in the storage tank 3 recycle.The capacity of storage tank 3 is about 30 liters, and it is provided with filler 14, can pass through filler Jia Shui in case of necessity.Also be provided with discharge outlet 15 on storage tank 3, the dilutional hyponatremia in storage tank 3 can overflow by discharge outlet 15.
In order fully to clean waste gas, to remove flue dust and pernicious gas in the waste gas, as, CO
2, SO
2Deng, between the inlet that cleans waste gas drum 1 and outlet, being disposed with buffering area 12, buffering trickle district 6 and the district 13 that blocks water, the width of buffering area 12 is about 1.5 times greater than the width that enters the mouth, the speed of the exhaust-gas flow that is used to slow down.Buffering trickle district 6 links to each other with cooling water tank 2, and width is about 1.5-2 times of buffering area 12, and the flow velocity of waste gas is further slowed down.The water of cooling water tank 2 can drench down from buffering trickle district 6, thereby the waste gas that enters is cleaned.In buffering trickle district 6, be provided with the baffle plate 10 that polylith is crisscross arranged at above-below direction, waste gas wriggles between each baffle plate 10 and flows, and flow velocity slows down, and can fully be cleaned by water.Baffle plate 10 setting that preferably slopes inwardly, after drenching water down and dropping on the baffle plate 10, can be along baffle plate 10 change directions, thus once more the waste gas of below is cleaned, can reach the purpose of abundant cleaning like this.In cleaning waste gas drum 1, by import and export, be provided with the district 13 that blocks water, this district 13 that blocks water comprises many exclusions water fine-structure mesh 8 and louvre blade 9, is used for filtering and discharges the entrained moisture of gas, is convenient to the recycling of water.
Preferably, the shell that cleans waste gas drum 1 is made of metal, and comprises the inner bag of being made by hot porcelain fiber, has good heat-insulating property, make the heat conduction feedwater of waste gas, and water temperature can not be subjected to the influence that exhaust emission pipe is heated, conducts heat.Afterwards, water is circulated to cooling water tank 2 and dispels the heat.In the vehicle driving process, can utilize wind speed to come cooling heat dissipation water tank 2, also can in cooling water tank 2, heat abstractor be set and dispel the heat, water temperature is remained on about the 25-28 degree, in recycling process, constantly take away the heat of waste gas.Cooling water tank 2 can be connected with cold air water discharge spout on the vehicle by cold air water collection pipe road 11, the cold air water in the vehicle is gathered cooling water tank carry out recycling.By the setting district 13 and cold air water collection pipe road 11 that blocks water, can prevent the evaporation and the loss of moisture, do not need frequent artificial recharge, the cold air water that mainly utilizes vehicle to produce every day carries out waste gas and cleans.
Below buffering trickle district 6, be provided with built-in reservoir chamber 7, be used to collect the water that buffering trickle district 6 flows down.Behind the water spray waste gas, wherein can leave suspended particles and dirt.Built-in reservoir chamber 7 is connected with filter 5, but collected water inflow filter 5 filters.In filter 5, be provided with active carbon and ion exchange resin, the former be used for adsorbed water impurity, purify waste water, the latter is used for exchanging mineral matter and toxin, and the water of inflow filter 5 is purified, so that flow into storage tank 3, carries out recycling.Also can use the filter of other type in the prior art.
As shown in Figure 2, the second embodiment of the present invention is applicable to oversize vehicle, and this mainly is to consider that the oversize vehicle exhaust gas discharged is more, and wherein identical with first embodiment part is not repeated.Waste gas among this embodiment cleans drum 1 and is separated into buffering area 12, buffering trickle district 6 and the district 13 that blocks water successively by a plurality of longitudinal divisions, the inlet that waste gas cleans drum 1 is connected with the outlet of the exhaust pipe of vehicle, and the waste gas that engine is produced enters buffering area 12.The width of buffering area 12 is about 1.5 times of inlet, the speed of the exhaust-gas flow that is used to slow down.The end of buffering area 12 links to each other with buffering trickle district 6.The width in buffering trickle district 6 is about 1.5 times of buffering area 12, can further slow down flowing velocity after waste gas enters, and helps abundant cleaning.In buffering trickle district 6, be provided with the baffle plate 10 that polylith is crisscross arranged on left and right directions, waste gas wriggles between each baffle plate 10 and flows, and flow velocity slows down, and can fully be cleaned by water.The preferably downward-sloping setting of baffle plate 10, after drenching water down and dropping on the baffle plate 10, can be along baffle plate 10 change directions, thus once more the waste gas of below is cleaned, can reach the purpose of abundant cleaning like this.
The end in buffering trickle district 6 links to each other with the district 13 that blocks water, and in the district 13 that blocks water, is provided with a plurality of fine-structure meshes 8 that block water, and is used for filtering and discharges the entrained moisture of gas, is convenient to the recycling of water.Waste gas cleans the outlet of drum 1 and discharges through fully cleaning from waste gas.
Utilize above waste gas cleaning device, can implement engine exhaust cleaning method of the present invention, specific as follows:
The waste gas of discharging from the exhaust pipe of vehicle is entered;
E. clean in the drum at waste gas, reduce the flowing velocity of waste gas;
F. make waste gas by cushioning the trickle district, waste gas is carried out spray Cleaning for High Capacity, impurities in waste gas enters in the water, and water is recycled simultaneously;
G. make waste gas after being cleaned by the district that blocks water, the moisture content that filtering is wherein carried.
In step C, the process that water is recycled comprises:
C1. collect the water under the district's pouring of buffering trickle;
C2. water is filtered;
C3. the water after will filtering is introduced storage tank;
C4. utilize electric pump that the water in the storage tank is drawn into cooling water tank;
C5. cooling water tank cleans to rouse with waste gas and links to each other, and water wherein sprays waste gas.
