Description

A kind of automobile exhaust filter

Technical field

The utility model belongs to vehicle maintenance service technical field, is specifically related to a kind of automobile exhaust filter.

Background technique

Along with the raising of people's living standard, automobile, diesel-oil vehicle rapidly increase.Create a large amount of harmful gases, in carbon black in gas and the floating air of finely ground particles, because floating debris particle is less than 10 microns, can several hours even several years all in atmosphere floating, make stuffy, not bright and clean, stale, particularly it can adhere to lung with the breathing of people, this air not only befouling environment, returns that people are healthy brings serious harm.

Existing vehicle maintenance service, mainly by being filtered by tail gas filter by vehicle exhaust.But the most complex structure of existing tail gas filter, cost is higher, is difficult to promote and not easy care.As a kind of automobile exhaust filter, it is made up of adsorption filtration layer, and it also has by water tank, circulating box, the exhaust box with suction tude, is connected each other with upper and lower pipe fitting, and the structure that water filling is wherein formed, adsorption filtration layer is arranged on the top of circulating box.Although the program can play tail gas filtering effect, its parts are more, complex structure, and cost is higher, add light weight simultaneously, add energy consumption, and this is current to energy-intensive, and its application is subject to a definite limitation.

Simultaneously, current automobile exhaust gas processing apparatus only has treatment device, there is no detection device and return reflux, tail gas after process does not meet air quality standard and is just discharged in air, thus befouling environment, in order to process vehicle exhaust well, can either filter vehicle exhaust in the urgent need to one, the device that can detect again vehicle exhaust solves existing problem.

Model utility content

The purpose of this utility model is to provide a kind of automobile exhaust filter, to solve the problem proposed in above-mentioned background technology.

For achieving the above object, the utility model provides following technological scheme: a kind of automobile exhaust filter, comprise admission line, tail gas filtering system, outlet pipe, tail-gas quality detection device, reflux line, exhaust port, described admission line is fixedly connected with tail gas filtering system by bolt, described tail gas filtering system is by filter screen, redox device, filter element combining device and silicon carbide filter device composition, described filter screen is fixedly connected with redox device with admission line respectively by pipeline, described redox device is connected with filter element combining device by pipeline, described filter element combining device is connected with silicon carbide filter device by pipeline, described silicon carbide filter device is connected with outlet pipe by pipeline, described tail-gas quality detection device is arranged on outlet pipe, described reflux line one end is fixedly connected with admission line, the other end is fixedly connected with outlet pipe, described exhaust port is arranged in the air outlet of outlet pipe.

Preferably, at least ten group parallel channels are provided with in described silicon carbide filter device.

Preferably, described tail-gas quality detection device is provided with solenoid valve.

Preferably, oxidation coating and reduction device is provided with in described redox device.

Technique effect of the present utility model and advantage: this automobile exhaust filter, silicon carbide filter device is provided with in tail gas filtering system, the duct end being entered silicon carbide filter device by the vehicle exhaust after filter element combining device filters enters duct, because the duct the other end is closed, gas molecule in vehicle exhaust enters adjoining cell channels by the hole wall of vent ability, the pollutant of vehicle exhaust cannot be filtered at ceramic hole wall surface by the micropore of hole wall because particle diameter is larger, thus reaches the effect of the pollutant eliminating vehicle exhaust; Outlet pipe arranges tail-gas quality detection device, when vehicle exhaust is after tail gas filtering system is filtered, can directly discharge after meeting gas discharging standard, if defective, solenoid valve will control tail-gas quality detection device and cut out outlet pipe, gas enters admission line from new through tail gas filtering system by reflux line, and this structure can make gas the best reach the requirement of gas discharging, and treatment effeciency is efficient; The utility model is through multiple filtration, solve the pollution problem of vehicle exhaust to greatest extent, in the hole exhaust of original automobile, become the exhaust of numerous aperture, change discharge directions, stop the dust on road surface is blown afloat and causes the pollution again of environment, and this automobile exhaust filter has environmental protection, simple and reliable for structure, to absorb sound, cheap, the feature such as easy to maintenance, greatly improves the quality of air.
