Technical field
The utility model relates to a kind of filtrating equipment, is specially a kind of filtrating equipment that is installed on the PM2.5 of automobile-use in filtering its tail gas.
Background technique
At present, the direct harm that causes of motor vehicle exhaust emission is the primary factor of present atmospheric pollution harm.Therefore annual and dead number is 10 times of traffic accident.Yet existing purifying vehicle exhaust mode mainly adopts the three-effect catalysis technology, but this technical disadvantages is to satisfy existing environmental protection requirement harmful gas; Can not eliminate the PM2.5 in the tail gas; The material rareness is expensive.
The model utility content
To be solved in the utility modelly be: utilize liquid to have the characteristic that absorbs the impurity in the gas, the tail gas that automobile is discharged carried out water filtration, and PM2.5 is wherein sponged by liquid fully.
A kind of device for the PM2.5 that filters motor-vehicle tail-gas that the utility model proposes comprises: tank body is positioned at the suction port of tank body one side, first one-way cock that is connected with suction port, the inner catheter that is connected with first one-way cock;
Be positioned at tank body one air outlet of side in addition, second valve that is connected with the air outlet;
Be positioned at the porous ceramics of tank base;
Be connected in the water filling hole of tank body, water outlet.
Further, inner catheter is connected with the porous ceramics that is positioned at tank base.
Further, in the ccontaining weakly alkaline solution of tank base.
Further, produce too much bubble in the container for preventing.The bubble filter layer is set in tank body, and the bubble filter layer adopts the filter medium of non-circular bore aperture, and medium surface itself is the thorn-like structure.
Further, for understanding the solution residual capacity in the tank body, in tank body water yield indicator is set.
Further, as a kind of possibility of the present utility model: the porous ceramic layer that is connected with described second valve is set.
Tail gas by first one-way cock and inner catheter, is delivered to the porous ceramics that tank base places weak base water by suction port.After tail gas enters this medium of porous ceramics, because porous ceramics has a large amount of holes, be a kind of filtering material, tail gas filters by porous ceramics, has the effect of a large amount of holes in the porous ceramics to be broken into the little foam of gas simultaneously.
The acid-base neutralization reaction is finished in the mixing of the tail gas after above-mentioned processing and weak base water.
Finish the MLV filter layer of tail gas by arranging in tank interior of acid-base neutralization reaction.The bubble filter layer adopts the filter medium of non-circular bore aperture, and medium surface itself is the thorn-like structure, can prevent from producing in the tank body too much bubble except defoaming.
At last, tail gas rises to second one-way valve and discharge the air outlet, then can install a porous ceramic layer additional at the second one-way valve place if further strengthen the tail gas clean-up effect.
In said process, in inlet and outlet port one-way cock is installed respectively, to prevent evaporation and the volatilization of liquid in the space, the flow direction of control gas; At tank body water filling hole and drain opening are set, are used for adding liquid and the reaction solution later of container; At tank body water yield indicator is set, is used for checking the solution residual capacity of separating container.
This technology not only can in and in the tail gas harmful matter of gas also can filter the effect that solid granule plays complete cleaning of off-gas, the utility model proposes a kind ofly directly is connected with the automobile exhaust hole for the flexible pipe of the PM2.5 device that filters motor-vehicle tail-gas by suction port, purified gas also can be discharged by the flexible pipe of air outlet, can be fixed in different ways on the diverse location of various vehicles, have wider applicability.
Compared with the prior art the utility model has apparent advantage: simple in structure, volume is little; Described assembly is all the ripe components and parts under the prior art, and then cheap for manufacturing cost, can produce in a large number, is convenient to change and safeguard.Because, and be applicable to that the production of new car also is suitable for the transformation of used car, be particularly useful for the tractor of some exhaust emissionss high-power high pollution not up to standard or the transformation of heavy-duty car.
Description of drawings
A kind of embodiment's for the PM2.5 device that filters motor-vehicle tail-gas that Fig. 1 proposes for the utility model plane structure schematic representation.
1. suction port 2. tank bodies 3. first one-way valves 4. bubble filter layers 5. inner catheters 6. porous ceramics 7. drain opening 8. water filling holes 9. second one-way valves 10. air outlets.
Embodiment
The utility model is described in further detail below in conjunction with embodiment of the present utility model.
The utility model proposes a kind of device for the PM2.5 that filters motor-vehicle tail-gas, comprising: tank body 2, be positioned at the suction port 1 of tank body 2 one sides, and 33 on first one-way valve that is connected with suction port 1 is with 33 inner catheters that are connected 5 of first one-way valve;
Be positioned at tank body 2 one air outlet 10 of side in addition, second valve that is connected with air outlet 10; Be positioned at the porous ceramics 6 that tank body 2 bottoms are connected with inner catheter 5; Be connected in the water filling hole 8 of tank body 2, drain opening 7.
Water filling hole 8 and drain opening 7 are used for injecting the solution that is used for Purge gas and discharging reacted discard solution toward tank body 2.In this embodiment of the present utility model, in and harmful gas CO in the tail gas, HC and NC etc. make it to meet fully the safety and environmental protection standard, solution adopts the low density urea water.
Tail gas by first one-way valve 3 and inner catheter 5, is delivered to the porous ceramics 6 that tank body 2 bottoms place weak base water by suction port 1.After tail gas enters porous ceramics 6 these media, because porous ceramics 6 has a large amount of holes, be a kind of filtering material, tail gas filters by porous ceramics 6, has the effect of a large amount of holes in the porous ceramics 6 to be broken into the little foam of gas simultaneously.
