Abstract
The utility model relates to a low temperature plasma coordinate direct current electric field tail purifier for automobiles, which is provided with a shell body (2). The upper part of the shell body is provided with an air inlet (1), and the lower part of the shell body is provided with an air outlet (3). The utility model is characterized in that the upper part in the shell body (2) is provided with a low temperature plasma generator (4). The lower part in the shell body (2) is provided with a multipolar plate type direct current electric field generator (5). The utility model can not only remove CO, hydrocarbon gas and NOX in tail gas of automobiles, but also can remove harmful substances, such as sulfide gas, dust, etc. The removal rate is over 90%. The utility model is not limited by oxygen content in tail gas and can thoroughly eliminate the phenomenon of smoking at tail part of automobiles.
Description
The utility model relates to a kind of gas purifier, particularly relates to a kind of low-temperature plasma synergistic DC electric field automobile exhaust purifier.
A kind of high section board automobile exhaust purifier is arranged in the market, and this product has a housing, and it has suction port and air outlet, and catalyzer is housed in the housing, and the latter can make CO, hydrocarbon gas (HC) and the NO in the vehicle exhaust
xRedox becomes CO
2, H
2O and N
2, three's conversion ratio is respectively 70%, 70% and 30%.This product has certain purifying effect to vehicle exhaust, but it only is applicable to gasoline car, and the air fuel ratio that requires automobile engine system is in normal range (NR), as oxygen content deficiency in the vehicle exhaust, then influence the conversion ratio of CO and HC,, then influence NO as too high oxygen level
xConversion ratio, not only purification ratio is not high for this purifier in other words, and is restricted when using, thereby automobile tail still has the phenomenon of smoldering.
The purpose of this utility model provides a kind of low-temperature plasma synergistic DC electric field automobile exhaust purifier, and it can remedy the above-mentioned deficiency of existing purifier.
The utility model has a housing, and its top has suction port, bottom that the air outlet is arranged, and it is characterized in that at the housing internal upper part low-temperature plasma generator being housed, and multipole board-like DC electric field generator is arranged at the bottom in the housing.
The utility model can be removed CO in the vehicle exhaust, hydrocarbon gas and NO
x, also can remove harmful matters such as sulfide gas and dust, eliminating rate also is not subjected to the restriction of oxygen content in the tail gas more than 90%, and can thoroughly eliminate the phenomenon of smoldering of automobile tail.
Below by embodiment and description of drawings the utility model.
Accompanying drawing is a structural representation of the present utility model.
The utility model has a housing (2), and suction port (1) is arranged at its top, and air outlet (3) is arranged at the bottom, it is characterized in that at housing (2) internal upper part low-temperature plasma generator (4) being housed, and multipole board-like DC electric field generator (5) is equipped with in the interior bottom of housing (2).It has 6 electrode plate, and alternate positive and negative is arranged.
When using the utility model, suction port (1) is connected on the vehicle exhaust discharge tube, the tail gas that automobile is discharged is entered in the multipole board-like DC electric field generator (5) CO in the tail gas, hydrocarbon gas, NO through low-temperature plasma generator (4) by suction port (1)
x, sulphur all harmful materials such as chemical compound gas become nontoxic material after through low-temperature plasma generators (4) and multipole board-like DC electric field generator (5), smoke particle in the tail gas is also owing on the charged electrode plate that is attracted to DC electric field generator (5), becomes big particle detachment at last and leaves tail gas.The tail gas of automobile has just purified up hill and dale like this.
Low-temperature plasma generator of the present utility model (4) and DC electric field generator (5) and circuit thereof are known, so its circuit diagram that do not draw.
Claims (1)
1. low-temperature plasma synergistic DC electric field automobile exhaust purifier, one housing (2) is arranged, its top has suction port (1), bottom that air outlet (3) is arranged, it is characterized in that at housing (2) internal upper part low-temperature plasma generator (4) being housed, multipole board-like DC electric field generator (5) is arranged at the interior bottom of housing (2).
