Description
Technical field
The present invention relates to a kind of guide plate three-element catalytic exhaust purifier.
Background technique
Along with the fast development of modern industry, the discharge etc. of sharply increase and the waste of vehicle, atmosphere polluting problem is more and more serious, and the environment also making the mankind depend on for existence obtains severe contamination, and the PM2.5 fine particle particularly in air is just in the involuntary health jeopardizing mankind itself.PM2.5 fine particle is mainly derived from motor vehicle exhaust emission and industrial waste gas, and PM2.5 fine particle can reach alveolar etc. deeply through respiratory tract to be organized and deposits, and then enters blood circulation, finally causes the various diseases such as lung cancer.And traditional automobile exhaust gas processing apparatus has good filtration for the particulate that particle is larger, and poor to the filtration of PM2.5 fine particle, therefore can not meet the process needs of people.
In order to improve the purifying effect of air, technician uses active carbon to purify vehicle exhaust.Such as publication number is that the patent document of CN204677266U discloses a kind of automobile exhaust purifier, its technological scheme is: comprise the purifier body that one end is connected with automobile exhaust pipe, described purifier body outer wall is circumferentially provided with first vent of giving vent to anger for vehicle exhaust, the outside that purifier body is positioned at the first vent is provided with tail gas clean-up room, be provided with the cavity volume for depositing active carbon bag between tail gas clean-up chamber interior walls and purifier body outer wall, tail gas clean-up chamber outer wall is circumferentially provided with the tail gas after for purification and discharges the second extraneous vent; Tail gas clean-up room is provided with for opening tail gas clean-up room and changing the construction of switch of active carbon bag, described construction of switch comprises side, tail gas clean-up room outer wall and extends the slide plate being provided with chute and coordinating clamping with chute along its length, and described chute is positioned at tail gas clean-up room and is provided with opening away from one end of automobile exhaust pipe.
In the technological scheme of above-mentioned patent document, by filtering vehicle exhaust at tail gas clean-up indoor storage active carbon bag, but because tail gas clean-up indoor do not arrange flow guide structure, vehicle exhaust directly causes vehicle exhaust filtration time short by tail gas clean-up room, and filtering effect is limited.
Summary of the invention
The invention is intended to provide a kind of guide plate three-element catalytic exhaust purifier, by arranging flow guide structure in tail gas clean-up indoor, extending the stroke of vehicle exhaust by tail gas clean-up room, increasing filtration time and improving filtering effect.
Guide plate three-element catalytic exhaust purifier in this programme, base case is: comprise tail gas clean-up room, two ends, tail gas clean-up room are communicated with outlet pipe with suction tude respectively, tail gas clean-up chamber interior is provided with vertical filter layer near one end of suction tude, tail gas clean-up chamber interior is provided with guide plate from filter layer to exhaust pipe end, guide plate comprises closed portion and three-element catalytic part, and the area of three-element catalytic part is less than the area of closed portion, three-element catalytic part on guide plate for be crisscross arranged up and down.
Working principle and beneficial effect: during work, vehicle exhaust enters tail gas clean-up room by suction tude, after the filtration treatment of tail gas clean-up room, is discharged by outlet pipe.Unlike the prior art, first, owing to being provided with filter layer, tail gas can first filter through filtering layer.In addition, owing to being provided with guide plate in tail gas clean-up indoor, guide plate is made up of closed portion and three-element catalytic part, and three-element catalytic part is less than closed portion, and blowing of ternary part on guide plate for be crisscross arranged up and down.After making tail gas enter tail gas clean-up room, linearly cannot pass through tail gas clean-up room, and can only along the three-element catalytic part turnover circulation on guide plate.Reduce the speed of tail gas, increase the time of tail gas in the process of three-element catalytic partial oxidation.Improve the effect of tail gas clean-up.
Scheme 2, as the improvement to base case, leaves gap between described filter layer and guide plate.Advantage is, makes tail gas enter gap between filter layer and guide plate after filtering layer filters, and makes tail gas even at gap internal air pressure, and then flows through three-element catalytic part.Avoid the tail gas backflow that air pressure inequality causes.
Scheme 3, as the improvement to base case, the filtering material that described filter layer inside is filled is active carbon.Advantage is, active carbon is better to the harmful gas assimilation effect in particulate matter and tail gas, improves the effect of filtering.
Scheme 4, as the improvement to base case, described three-element catalytic part is that ceramic honeycomb carrier adheres to aluminium oxide catalyst.Advantage is, is conveniently easy to get, cheap.
Scheme 5, as the improvement to base case, the sidewall of described tail gas clean-up room is provided with end cap.Advantage is, conveniently changes filter layer and guide plate.
Accompanying drawing explanation
Fig. 1 is the structural representation of guide plate three-element catalytic exhaust purifier embodiment of the present invention.
Embodiment
Below by embodiment, the present invention is further detailed explanation:
Reference character in Figure of description comprises: suction tude 10, tail gas clean-up room 20, end cap 21, filter layer 22, guide plate 23, three-element catalytic part 24, outlet pipe 30.
Embodiment
As shown in Figure 1, guide plate three-element catalytic exhaust purifier, scheme is: comprise tail gas clean-up room 20, two ends, tail gas clean-up room 20 are communicated with outlet pipe 30 with suction tude 10 respectively, inner one end near suction tude 10, tail gas clean-up room 20 is provided with vertical filter layer 22, inside, tail gas clean-up room 20 is provided with guide plate 23 from filter layer 22 to outlet pipe 30 end, guide plate 23 comprises closed portion and three-element catalytic part 24, the area of three-element catalytic part 24 is less than the area of closed portion, three-element catalytic part 24 on guide plate 23 for be crisscross arranged up and down.
In addition, in the present embodiment, gap is left between filter layer 22 and guide plate 23.Advantage is, makes tail gas enter gap between filter layer 22 and guide plate 23 after filtering layer 22 filters, and makes tail gas even at gap internal air pressure, and then flows through three-element catalytic part 24.Avoid the tail gas backflow that air pressure inequality causes.The filtering material that filter layer 22 inside is filled is active carbon.Advantage is, active carbon is better to the harmful gas assimilation effect in particulate matter and tail gas, improves the effect of filtering.Three-element catalytic part 24 adheres to aluminium oxide catalyst on ceramic honeycomb carrier.Advantage is, is conveniently easy to get, cheap.The sidewall of tail gas clean-up room 20 is provided with end cap 21.Advantage is, conveniently changes filter layer and guide plate.
