A kind of vehicle exhaust trapping purification plant
Technical field
The utility model relates to a kind of gas filtration segregating unit, especially relates to a kind of vehicle exhaust trapping purification plant.
Background technique
The pollutant that vehicle exhaust contains generally has carbon monoxide, hydrocarbon, oxynitrides, particulate matter and sulphide.Most of with gaseous form, exist, particulate matter contains plumbous compound, sulphate, low-molecular material, and the porosity carbon granules of diameter 0.1-10UM of take is dominant shape formula.Tail gas is met after air after discharging, and the hydrogenesis of part and air, becomes water.General such tail gas of processing can adopt gas filtration segregating unit.As Chinese patent notice of authorization number: CN1919427, in the patent document of on 02 28th, 2007 notice of authorization day, a kind of automobile exhaust gas processing apparatus is disclosed, it comprises filtrating equipment, filtrating equipment can use charcoal plate, for filtering the solid particle of vehicle exhaust, vehicle exhaust is processed material can use TiOx nano coating, with light source, irradiate TiOx nano coating, enable fully to absorb and process nitrogen oxide, it can be contained in after the outlet pipe of automobile, for the treatment of vehicle exhaust, reduces atmospheric pollution.
Existing auto vendor is when carrying out automobile factory testing, processing for vehicle exhaust just arranges the suction port of a rectangular band grid in automobile exhaust pipe rear end, the Zai Yu center of circle, rear end ventilator is delivered to air bells exhauster, utilizes the pressure of air bells exhauster, through vertical air channel, is expelled to outdoor.This processing mode is deposited shortcoming in the following areas: tail gas and intake grill are at a distance of a segment distance, and the condensation vapor in tail gas becomes water-water reactor long-pending on the ground, causes ground humidity dirty; Intake grill size is large, and far away again with outlet pipe distance, tail gas cannot all be collected, and part spreads to workshop, atmospheric pollution weight.
Model utility content
The utility model is tail gas collecting to be purified when overcoming automobile factory testing improperly, causes the deficiency of indoor pollution, provides a kind of tail gas collecting effective, the vehicle exhaust trapping purification plant that indoor pollution is few.
To achieve these goals, the utility model is by the following technical solutions:
A kind of vehicle exhaust trapping purification plant of the present utility model, comprises tapered sleeve, bend pipe, U-shaped pipe, adsorbent equipment, described U-shaped pipe one end bridge piece, and the bend pipe the other end connects trumpet-shaped tapered sleeve, and the U-shaped pipe the other end connects adsorbent equipment; U-shaped pipe bend place is provided with a ponding chamber, and bottom, ponding chamber connects waste pipe.Trumpet-shaped tapered sleeve horizontal positioned, big opening end is aimed at automobile exhaust pipe, and tail gas is directly entered in tapered sleeve.U-shaped pipe bend place horizontal positioned, straight up, reflux and enter ponding chamber after the steam natural condensation in tail gas in both sides, and the discontinuity draining of ponding chamber, introduces the water-collecting machine in factory by sewage.Adsorbent equipment is mainly to filter tail gas, and adsorbent equipment is communicated with factory's exhaust system, outside the tail gas discharge chamber after filtration.
As preferably, the mouth of pipe place that described waste pipe is connected with ponding chamber is provided with drain valve.After being installed, drain valve the water discontinuity in ponding chamber can be discharged automatically, and without manual control, more convenient.
As preferably, described bend pipe is a bellows.Dissimilar automobile chassis height is slightly different, and bellows has certain stretchability, can regulate height and the angle of tapered sleeve, makes tapered sleeve can accurately aim at automobile exhaust pipe.
As preferably, described adsorbent equipment is the pipe that active carbon is housed.Active carbon adsorption is good, is convenient for changing, and cost is not high.
The utlity model has following beneficial effect: tapered sleeve can directly be aimed at automobile exhaust pipe, and tail gas collecting is effective, on-the-spot pollution is low.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure: tapered sleeve 1, bend pipe 2, U-shaped pipe 3, adsorbent equipment 4, ponding chamber 5, waste pipe 6, drain valve 7.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
In embodiment as shown in Figure 1, a kind of vehicle exhaust trapping purification plant, comprises tapered sleeve 1, bend pipe 2, U-shaped pipe 3, adsorbent equipment 4.Bend pipe 2 is bellowss, has stretchability.U-shaped pipe 3 elbows are provided with a ponding chamber 5, and U-shaped pipe 3 and ponding chamber 5 levels are fixed on ground, and U-shaped pipe 3 both sides vertically erect, U-shaped pipe 3 one end bridge pieces 2, bend pipe 2 the other ends connect tapered sleeve 1, and tapered sleeve 1 is horn-like, and tapered sleeve 1 osculum end face is connected with bend pipe 2.U-shaped pipe 3 the other ends connect adsorbent equipment 4, and adsorbent equipment 4 is for being equipped with the pipe of active carbon.5 bottoms, ponding chamber connect waste pipe 6, and the mouth of pipe place that waste pipe 6 is connected with ponding chamber 5 is provided with drain valve 7.Waste pipe 6 is communicated with the water-collecting machine of factory, and adsorbent equipment is communicated with factory's exhaust system.Outside tail gas discharge chamber after filtration
Automobile enters test position along the track of setting in workshop, makes 1 mouthful of the corresponding tapered sleeve of outlet pipe of automobile, and workman is according to the height of carriage underframe and shape, and fine setting ripple bend pipe 2, makes the big opening end of tapered sleeve 1 in the face of prospective vehicle outlet pipe.After steam natural condensation in tail gas, reflux and enter ponding chamber 5, by waste pipe 6, enter factory's water-collecting machine.In tail gas, other waste gas, after active carbon adsorption, enter outside exhaust system discharge chamber.
