Abstract
The invention discloses a PPS (Polyphenylene Sulfide) multistage filter for automobile tail gas, which is used as a tail gas deeply purifying additional device behind a ternary filter for an automobile. An atomizing humidifying unit and a micro-powder filter unit are arranged on the filter; the atomizing humidifying unit is provided with an atomizing nozzle, a gas inlet and an exhaust port; the gas inlet is connected with the exhaust port of the ternary filter; the exhaust port is communicated with the entering gas of the following micro-powder filter unit; a PPS non-woven fabric filter system is arranged on the micro-powder filter unit; the filter system is provided with at least three filter layers; and activated carbon layers are arranged between the filter layers. After the tail gas passing by the ternary filter enters into the PPS multistage filter provided by the invention, the acid gas and the micro-powder are further filtered, so that the automobile tail gas is further purified and the damage to the urban air is relieved.
Description
Affiliated technical field
The present invention relates to vehicle exhaust and handle, plan reaches PM2.5 air index, and especially the tail-gas deep purification apparatus is made the field.
Background technique
In automobile exhaust gas processing apparatus, the three-way catalytic converter technology is to use maximum purification technicss at present.When engine operation, tail gas gets into catalyst converter through outlet pipe, and wherein reducing agents such as the carbon monoxide in nitrogen oxide and the tail gas, hydrogen resolve into nitrogen and oxygen under catalysis; And hydrocarbon and carbon monoxide respectively with waste gas in oxygen abundant oxidation under catalysis of generating of remaining oxygen and last reaction, generate carbon dioxide and water vapour.Because catalyzer is a cellular structure in the ternary catalyzing unit, the honeycomb surface scribbles catalysis material, and is long-pending very big with the contact surface of waste gas, so its purification efficiency is very high.Through test, when the air fuel ratio of motor, the ratio of air and fuel just is near near the chemically correct fuel time, and three-way catalyst can purge 90% the hydrocarbon and the nitrogen oxide of carbon monoxide and 70% simultaneously.Because can purify three kinds of pollutants simultaneously, therefore this catalyst converter is called as three-way catalytic converter.But raising gradually along with human environment consciousness; People are also increasingly high to the requirement of own living environment; Emission limit to automobile is constantly strict, and the micro mist in the tail gas also is the index that city PM2.5 standard need be controlled, and AUTHORITATIVE DATA shows; The automotive emission atmosphere pollution accounts for 22%, has been the main source of pollution of atmosphere. and the further elimination of acid ingredient and micro mist is the new demands of people to vent gas treatment and urban environmental protection in the discharge gas of existing three-way catalytic converter.
Summary of the invention:
In view of the above deficiency of existing technology, the objective of the invention is to study a kind of vehicle exhaust multistage filter that vehicle exhaust is carried out sour gas and micro mist filtering behind the conventional three-way catalytic converter that is attached to, make it to overcome the above shortcoming of existing technology.
The objective of the invention is to realize through following means:
Polyphenylene thioether PPS vehicle exhaust multistage filter is used for behind the ternary filter, purifying additional device as tail-gas deep, and filter is provided with spraying humidification unit and micro mist filter element; Said spraying humidification unit has fog head, suction port that is connected mutually with ternary filter relief opening and the relief opening that communicates with the air inlet of follow-up micro mist filter element; Said micro mist filter element is provided with the polyphenylene thioether PPS nonwovens and filters system, and said filtration is to have the three layer filtration layer at least, between filter layer, is provided with active carbon layer.
Adopt structure of the present invention; Vehicle exhaust sour gas and micro mist obtain further filtering; The polyphenylene thioether PPS nonwovens filters system with good filtration and the adsorption performance of its excellent high-temperature machinery intensity maintenance in the hot environment of vehicle exhaust; Vehicle exhaust is further purified, alleviate acid waste gas and 2.5 microparticles content in the urban air.PPS fiber good heat stability, it has outstanding heat-resisting quantity, and fusing point reaches 285 ℃, is higher than other melt spun fibres of present industrialized production, so dimensionally stable.Its LOI can reach 35% one 45%, under normal atmospheric conditions, can not burn.The heat resistance of polyphenylene sulfide fibre also shows: its strength retention in the time of 200 ℃ is about 40% when being 60%, 250 ℃.Below 250 ℃ the time, its breaking elongation remains unchanged basically.
