Abstract
The utility model discloses a diesel engine tail gas processing apparatus has solved the problem that present diesel engine tail gas processing apparatus box is bulky, the area water yield is big, exhaust resistance is big. The technical scheme includes that the fire-retardant fire-protection box comprises a box body, wherein an air inlet and an air outlet are formed in the box body, and a fire-retardant fence is arranged in the box body; at least one lower guide plate is vertically arranged on the inner bottom surface of the box body, and a gap is reserved between the upper end of the lower guide plate and the top surface of the box body; the upper guide plate and the lower guide plate are arranged at intervals. The utility model discloses simple structure, box are small, effectively reduce the exhaust resistance of diesel engine, tail gas treatment is effectual.
Description
Technical field
The utility model relates to a kind of automobile component, a kind of specifically diesel engine vent gas treatment device.
Background technique
At present; Known diesel engine vent gas treatment device is that an exhaust manifold is connected with the suction port of casing; By at the bottom of the gas leading-in box of an air pipe with the diesel engine discharge, be in charge of by several again then and draw again, gas is cleaned in water one time; And then by water treatment plant aqueous vapor is separated, make outside the air scavenge case.This structure has following shortcoming: 1; Diesel exhaust gas pressure is big, if the stroke of gas in water is too small, then can make by the water amount of casing discharge gas bigger; Therefore design the casing volume comparatively huge usually; In casing, cross the water stroke to prolong gas, and excessive casing can influence the chassis and arranges, increases the deadweight of car amount; 2, the back-fire relief fence in the casing is arranged on the position near suction port usually, and the exhaust resistance of diesel engine will increase greatly like this, also just reduce the effective output of diesel engine.
Summary of the invention
The purpose of the utility model is in order to solve the problems of the technologies described above, provide a kind of simple in structure, the casing volume is little, effectively reduce the effective diesel engine vent gas treatment device of exhaust resistance, vent gas treatment of diesel engine.
Technological scheme comprises casing, establishes suction port and relief opening on the said casing, and the back-fire relief fence is housed in the said casing, and said box top is provided with at least one baffle upper plate vertically downward, and the gap is left with tank floor in said baffle upper plate upper end; Said casing inner bottom surface is provided with at least one chin spoiler vertically upward, and the gap is left with box top in said chin spoiler upper end; Said baffle upper plate and chin spoiler are provided with at interval.
Said back-fire relief fence is installed near exhaust ports.
Have the filter pore on the said baffle upper plate of liquid level below and/or the chin spoiler in the casing.
Through establishing upper and lower guide plate is set at interval at casing; Make casing be separated into a gallery that is interconnected, flow in the gallery that gas (being diesel engine vent gas) is formed between guide plate and gap by suction port to relief opening direction, prolonged the stroke that gas is crossed water; When having solved the gas entraining water problem that diesel exhaust gas pressure brings greatly; Also dwindled the volume of casing, said upper and lower guide plate is with the effect of water conservancy diversion and drainage, and the quantity of its setting is set according to the exhaust pressure of water tank size and diesel engine; The filter pore that has can increase gas throughput as crossing the gas bypass when diesel exhaust gas pressure is excessive; Further, back-fire relief fence repacking near exhaust ports, under the situation that does not influence original function, has been solved and has been installed near the influence to the effective output of diesel engine of the back-fire relief fence at suction port place.
Beneficial effect: the utility model is simple in structure, the casing volume is little, and it is convenient to make, and the useful horsepower that can improve diesel engine is more than 10%, vent gas treatment effective (carbon monoxide and oxynitrides reduce by 20% than standard-required).
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1-casing, 2-suction port, 3-relief opening, 4-baffle upper plate, 5-baffle upper plate, 6-chin spoiler, 7-back-fire relief fence, 8-level controling mechanism, 9-filter pore.
Embodiment
Below in conjunction with accompanying drawing the utility model is further explained:
With reference to Fig. 1, establish suction port 2 and relief opening 3 and level controling mechanism 8 on the casing 1, said casing 1 end face is provided with two baffle upper plates 4,5 vertically downward, and the gap is left in said baffle upper plate 4,5 upper ends and casing 1 bottom surface; Said casing 2 inner bottom surfaces are provided with a chin spoiler 6 vertically upward, and said chin spoiler 6 upper ends and casing 1 end face leave the gap; Said chin spoiler 6 is installed in two baffle upper plates 4 at interval, between 5, the position that said baffle upper plate 4,5 is positioned at casing liquid level below also has filter pore 9; Back-fire relief fence 7 is arranged near said relief opening 3 places.
Working principle: diesel engine vent gas is got in the casing by suction tude, and current downflow on the gallery that a plurality of guide plates in gas edge constitute in casing 1 is finally discharged by relief opening 1 through back-fire relief fence 7.
Claims (3)
1. a diesel engine vent gas treatment device comprises casing, establishes suction port and relief opening on the said casing; The back-fire relief fence is housed in the said casing; It is characterized in that said box top is provided with at least one baffle upper plate vertically downward, the gap is left with tank floor in said baffle upper plate upper end; Said casing inner bottom surface is provided with at least one chin spoiler vertically upward, and the gap is left with box top in said chin spoiler upper end; Said baffle upper plate and chin spoiler are provided with at interval.
2. diesel engine vent gas treatment device as claimed in claim 1 is characterized in that, said back-fire relief fence is installed near exhaust ports.
