Abstract
The utility model relates to an engine tail gas purification device which belongs to the technical field of exhaust gas purification. The utility model provides the technical schemes solving technical problems that the improved engine tail gas purification device comprises a purification box, wherein washing liquor is filled in the box; an air inlet pipe of the purification box is connected with an exhaust pipe of an engine; a thimble valve is arranged on the air inlet pipe; the thimble valve comprises a spring, a draw rod and a valve cap. When the engine is started, the draw rod is lifted upwards to make the valve opened, and thus the air inlet pipe is communicated with atmosphere. After the engine successfully ignites, the draw rod is put down; the valve closes; the engine tail gas is discharged out after absorbed and cleaned by the washing liquor in the purification box.
Description
Technical field
The utility model belongs to the waste-gas cleaning technical field, relates to a kind of engine tail gas purification device of improvement.
Background technique
Motor exhaust contains a large amount of harmful gas compositions, contaminated air, and particularly in the city, the tail gas that a large amount of motor vehicle engines is discharged causes serious pollution to urban environment, and the infringement people's is healthy.In order to reduce the pollution of motor exhaust to air, a lot of cities begin the development of limiting vehicle, and this has not only brought influence to the development of national economy, and have brought a lot of troubles for people's life.
So, the technology of handling at automobile engine tail gas also constantly develops, such as the patent No. is 96234001.4 " engine tail gas purification device " is exactly a kind of technology of typical engines tail gas disposal, it is to install a purifying box behind engine exhaust pipe additional, when motor is in running order, make motor exhaust by the purifying box of wash water is housed, thereby reach the purpose of air purification.But, this technology exists an obvious defects, under this structure, since engine exhaust pipe be fully immersed in the wash water of purifying box after the suction tude of purifying box links to each other, start working at that moment at engine ignition, owing to must overcome the pressure of liquid, cause motor to be difficult to start.
The model utility content
At the above-mentioned defective that exists in the prior art, the utility model provides a kind of engine tail gas purification device.
The technological scheme that solving the utility model technical problem is provided is that this engine tail gas purification device includes a purifying box, wash water is housed in the case, the suction tude of purifying box is connected with waste pipe, a thimble valve is arranged on suction tude, thimble valve comprises a spring, pull bar and valve gap, when ato unit, last lifting rod is with valve open, make suction tude communicate with atmosphere, after the engine ignition success, put down pull bar, valve closes, motor exhaust absorbs, cleans the back by the wash water of purifying box and discharges.
By implementing the beneficial effects of the utility model is that it has not only reached purpose to engine tail gas purification, has solved a key technical problem that exists in the prior art simultaneously, makes present technique have more realistic meaning.
Description of drawings
Below in conjunction with embodiment's accompanying drawing the utility model is described in further detail.
Fig. 1 is the utility model embodiment schematic perspective view;
Fig. 2 is the structural representation of the utility model thimble valve.
Among the figure, 1-suction tude, 2-purifying box, 3-liquid-feeding tube, 4-liquid discharging valve, 5-liquid mark pipe, 6-thimble valve, 7-spring, 8-pull bar, 9-valve port, 10-valve gap
Embodiment
As for embodiment of the present utility model, see also accompanying drawing, as can be seen from Figure 1 the utility model includes a purifying box 2, purifying box 2 includes suction tude 1, liquid-feeding tube 3, liquid discharging valve 4, liquid mark post 5, purified solution in the purifying box 2, can adopt water, perhaps add an amount of washing agent in water, washing agent is to the co in the tail gas, so
2, co
2Gas has absorption, and can wash away the grit that does not burn in the tail gas.Liquid mark pipe 5 is arranged on the side of purifying box 2, and it can be glass tube or transparent anti-rot plastic pipe, is convenient to observe the liquid level of wash water in the purifying box 2.Suction tude 1 is deep into the bottom of purifying box 2, the purpose of process to reach absorption and to wash of utilizing tail gas to rise from the bottom in wash water.Liquid-feeding tube 3 is that the wash water of purifying box 2 adds inlet, also is the exhaust port of cleaning of off-gas.
See also Fig. 2, the structural representation of Fig. 2 the utility model thimble valve 6, the major character that the utility model is different from prior art just is to have increased thimble valve 6 on suction tude 1, its structure as shown in the figure, it includes a spring 7, pull bar 8, valve gap 10, in the thimble valve 6, pull bar 8 is fixedlyed connected with valve gap 10, and spring 7 is enclosed within on the pull bar 8.In the time of concrete enforcement, suction tude 1 of the present utility model is connected with waste pipe, in engine ignition, during last lifting rod 8, valve gap 10 is opened, and this moment, suction tude 1 communicated the inner and outer air pressure unanimity with atmosphere, motor is retrofire easily, after engine start, constantly outwards discharge tail gas by outlet pipe, put down pull bar 8 this moment, under the elastic pressure of spring 7, valve gap 10 is closed, and this moment, suction tude did not communicate with ambient atmosphere, and tail gas enters purifying box 2 by suction tude 1, be absorbed, washing, thus reached the purpose that purifies air.
