Description
Technical field
The utility model relates to a kind of cavern space tail gas purification device of combustion engine, be applicable to need cleaning internal combustion engines to produce the operation process of tail gas, belong to cavern con struction field, when producing under being applicable to the obstructed environment of air such as mine down-hole operation, tunneling, tunnel operation, use combustion engine powered engineering.
Background technique
In cavern excavation blast working, a large amount of rubble will be produced, the slag-tapping devices such as loader need be used to carry out slagging tap operation, slagging tap in operation process, automotive diesel oil burning can produce a large amount of Tail Gas, cause harmful gas in tunnel to be piled up, not only affect the healthy of workmen, and affect traffic safety.Therefore, invent a kind of cavern space tail gas purification device of combustion engine and be applied to, in engineering practice, be very important, there is important economic implications and social effect.
At present, the domestic tunnel air purifier that generally uses purifies on the spot to tunnel air, but tunnel air purifier has its narrow limitation, only can be used in the tunnel excavated, for the tunnel air purification problem do not excavated, domesticly there is no effective solution at present, therefore how effectively to purify the exhaust gases of internal combustion engines in tunnel, is need the research topic of carrying out in current tunnel construction badly.
For the air purification of cavern, also can use special diesel exhaust purifier, but its cost of use is high, and high to the engine calls of slag-tapping device, do not allow to burn the catastrophe failure such as cylinder, burn oil, can not poor ignition quality fuel be used; During the serious burn oil of motor, (blue smoke is emitted in exhaust) can make purifier poison deactivation; During each engine overhaul, need to change purifier.Mounting point requires more near better with motor, and the exhaust pipe length of distance enmgine exhaust is no more than one meter.Suggestion is directly installed after outlet pipe or after turbine increase device.Mounting point must before silencing apparatus, namely between motor and silencing apparatus.
Summary of the invention
Problem to be solved in the utility model be to provide a kind of can be used for the obstructed environment of air under use combustion engine powered engineering of carrying out operation when producing, object is the Tail Gas that cleaning internal combustion engines burning produces, compared with traditional exhaust gas cleaner, this purification plant should have that expenditure of construction is low, mounting or dismounting are convenient, simple operation and other advantages.Meanwhile, for ensureing air purification effect, this purification plant should have good air purification effect.
For solving the problems of the technologies described above, the technical solution of the utility model is, a kind of cavern space tail gas purification device of combustion engine comprises suction chamber, exhaust chamber, is connected between suction chamber with exhaust chamber by outlet pipe;
Described suction chamber is connected by pipeline with internal combustion engine exhaust silencer, and described exhaust chamber built with purified solution, and arranges multiple dividing plate exhaust chamber is separated into multiple region, and outlet pipe one end is stretched in exhaust chamber;
Be provided with telescopic cover in the middle of described outlet pipe, telescopic cover comprises at least two retainer rings, is connected between retainer ring by rubber tape, and retainer ring is fixed on exhaust tube wall, and the exhaust tube wall between two retainer rings is provided with filtering hole.
Further, establish exhaust post in filtering hole, described exhaust post is the cylinder of one end open, inner hollow, and non-opening end sidewall is provided with air dispelling hole.
Further, exhaust chamber is provided with waste liquid exhaust port.
The utility model has the advantages that, reasonable in design is reliable, effectively improves the ability of continuous purification exhaust gases of internal combustion engines; Purification plant mounting or dismounting are convenient, can clean at any time; Be welded on exhaust gases of internal combustion engines pipe, do not need to carry etc. separately.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is telescopic cover preferred structure schematic diagram.
As in figure, suction chamber 1, exhaust chamber 2, outlet pipe 3, dividing plate 4, telescopic cover 5, retainer ring 6, rubber tape 7, filtering hole 8, exhaust post 9, air dispelling hole 10.
Embodiment
As in Fig. 1, a kind of cavern space tail gas purification device of combustion engine comprises suction chamber 1, exhaust chamber 2, is connected between suction chamber 1 with exhaust chamber 2 by outlet pipe 3;
Suction chamber 1 is connected by pipeline with internal combustion engine exhaust silencer, exhaust chamber 2 is built with purified solution, and multiple dividing plate 4 is set exhaust chamber 2 is separated into multiple region, preferred multiple region is in vertical arrangement, multiplely interregionally to be interconnected, the bottommost region in exhaust chamber 2 is stretched in outlet pipe 3 one end, during work, the tail gas that internal-combustion engine produces is entered the bottommost of exhaust chamber 2 by outlet pipe 3, rise to the discharge of exhaust chamber 2 top from bottommost again and successively through different regions, thus the purified treatment to tail gas can be realized therebetween.
Telescopic cover 5 is provided with in the middle of outlet pipe 3, telescopic cover 5 comprises at least two retainer rings 6, connected by rubber tape 7 between retainer ring 6, retainer ring 6 is fixed on outlet pipe 3 outer wall, outlet pipe 3 outer wall between two retainer rings 6 is provided with filtering hole 8, preferably, exhaust chamber 2 is provided with waste liquid exhaust port 9, during work, when tail gas enters exhaust chamber 2, because be separated by multiple region therebetween, extend dodds purification route, but the air pressure simultaneously too increased during exhaust, particularly a certain period tail gas increases, when the exhaust velocity value added of exhaust chamber 2 is less than tail gas value added, backpressure will be produced, make exhaust gas flow direction internal-combustion engine direction, affect the work of internal-combustion engine, by arranging telescopic cover 5, utilize the deformable feature of rubber tape 7, thus (fluctuating range is little to make the air pressure in outlet pipe 3 keep certain constant, can slightly disregard),
Establish exhaust post 9 in filtering hole 8, as Fig. 2, exhaust post 9 is the cylinder of one end open, inner hollow, and non-opening end sidewall is provided with air dispelling hole 10.Exhaust post 9 opening end wherein in a filtering hole 8 is towards outlet pipe 3, another part crosses exhaust post 9 opening end in filtering hole 8 towards rubber tape 7, during work, when the air pressure in outlet pipe 3 increases, when exceeding limit value, exhaust post 9 opening end is ejected filtering hole 3 (the non-opening end of exhaust post 9 is ejected filtering hole 3) towards outlet pipe 3 by gas in outlet pipe 3, and the gas in outlet pipe 3 will be entered in telescopic cover 5 by air dispelling hole 10, rubber tape 7 is out of shape, when outlet pipe 3 internal air pressure diminishes, when air pressure in telescopic cover 5 is higher than outlet pipe 3, exhaust post 9 opening end is ejected filtering hole 3 (the non-opening end of exhaust post 9 is ejected filtering hole 3) towards rubber tape 7 by gas in telescopic cover 5, and by by air dispelling hole 10, the gas in telescopic cover 5 is entered in outlet pipe 3.
