Description
Technical field
The utility model is related to automobile manufacturing field, specifically a kind of car tail-gas filter, is primarily adapted for use in automobile
Blast pipe.
Background technology
Existing car tail-gas filter, it is a kind of as disclosed in the patent of invention that application publication number is CN105927318A
" car tail-gas filter ", the device of pollutant in vehicle exhaust can be filtered by being one, and automobile is the master of earth atmosphere now
Pollution sources are wanted, this device inhales the pollutant in tail gas by vehicle exhaust being blown to the water surface of square plastic keg, water
Receipts are fallen, and the blowing force of tail gas makes water constantly circulate to be dissolved into water pollutant, and car tail-gas filter is on probation with any automobile
The pollutant in tail gas can be very filtered with internal combustion engine.But its structure is excessively complicated, manufacturing cost is high, it has not been convenient to use
With installation.
Utility model content
The purpose of this utility model is to provide a kind of car tail-gas filter, fundamentally solves above mentioned problem, and it has
There are low simple and compact for structure, convenient to use, maintenance cost, service life length, good filtration effect, applied widely etc. excellent
Point.
To achieve the above object, the utility model provides following technical scheme：The car tail-gas filter includes housing,
It is relative on housing to be provided with air inlet pipe and blast pipe, it is characterised in that：Baffle plate is provided with the housing, between baffle plate and housing bottom surface
Installation filter screen in gap, gap is left, provided with the pressure reductor being vertically fixed in housing bottom surface between air inlet pipe and baffle plate, decompression
The most upper edge of plate is higher than baffle plate most lower edge, provided with the spoiler that gap is left with housing bottom, spoiler between baffle plate and blast pipe
Most upper edge is less than the most upper edge of pressure reductor, and the housing sidewall between pressure reductor and blast pipe is provided with overflow pipe and water inlet pipe, overflow
The most upper edge of the water inlet end of pipe be less than the most upper edge of pressure reductor, or with pressure reductor most on along maintain an equal level.
The housing bottom of the blast pipe side is provided with drainpipe, and drainpipe is provided with magnetic valve.
The air inlet pipe or blast pipe include the shell with cavity, the spacing grid frame in shell cavity, grid
The waterproof layer that is made from inside to outside provided with inner tube shell, resin in uniform some stomatas, grid frame on framework, polyurethane into
Hydrophobic layer and outer tube shell.
The beneficial effects of the utility model：It is provided with when air-flow is discharged in the enterprising air chamber of baffle plate to produce in sound revolution inlet plenum
Silencing means, tail gas can be crushed air pocket by filter screen, and on the one hand pressure reductor reduces the resistance of vehicle exhaust, on the other hand may be used
Tank is surrounded in housing.The pollution that various motor vehicle exhaust emissions are produced is applicable to, so as to eliminate the tail gas in PM2.5.It is logical
The air inlet pipe or blast pipe for being provided with layer of polyurethane and resin bed are crossed, noise can be effectively reduced.
Brief description of the drawings

Fig. 2 is operation principle schematic diagram of the present utility model；
Fig. 3 is the utility model air inlet pipe or the cross section structure diagram of blast pipe.
Description of reference numerals：1 air inlet pipe, 2 blast pipes, 3 baffle plates, 4 filter screens, 5 pressure reductors, 6 spoilers, 7 overflow pipes, 8 are entered
Water pipe, 9 drainpipes, 10 stomatas, 11 grid frames, 12 hydrophobic layers, 13 waterproof layers.
Embodiment
Below in conjunction with Fig. 1 ~ 3, content of the present utility model is described in detail by specific embodiment.The car tail-gas filter
It is relative on housing to be provided with air inlet pipe 1 and blast pipe 2, housing provided with the baffle plate 3 being vertically arranged, baffle plate 3 and housing including housing
Gap is left between bottom surface, gap is closed by filter screen 4, be provided with and be vertically fixed in housing bottom surface between air inlet pipe 1 and baffle plate 3
Pressure reductor 5, the most upper edge of pressure reductor 5 is higher than the most lower edge of baffle plate 3, is provided between baffle plate 3 and blast pipe 2 between leaving with housing bottom
The spoiler 6 of gap, the most upper edge of spoiler, which is less than in the most upper edge of pressure reductor 5, the housing sidewall between pressure reductor 5 and blast pipe 2, to be set
There are overflow pipe 7 and water inlet pipe 8, the most upper edge of water inlet end of overflow pipe 7 is less than the most upper edge of pressure reductor 5, or is held with the most upper edge of pressure reductor 5
It is flat.The housing bottom of the side of blast pipe 2 is provided with drainpipe 9, and drainpipe 9 is provided with magnetic valve.Air inlet pipe or blast pipe include carrying
In the shell of cavity, the spacing grid frame 11 in shell cavity, grid frame in uniform some stomatas 10, grid frame by
The waterproof layer 13 that is made from inside to outside provided with inner tube shell, resin, polyurethane into hydrophobic layer 12 and outer tube shell.
In use, the water filling into housing by water inlet pipe, water is full of baffle plate both sides under connection effect, excessive water passes through
Overflow pipe is discharged.It is passed through when tail gas is entered by the air inlet pipe 1 connected with exhaust main in housing in water, passes through the filter of baffle bottom
Net 4 is broken into after tiny bubble, and bubbles strike spoiler 6 is produced after flow-disturbing, the purpose of noise reduction can be played, finally by blast pipe 2
Discharge, realizes the filtering of vehicle exhaust.
