Description
Technical field:
This utility model belongs to purifying vehicle exhaust aspect technical field, particularly relates to a kind of automobile exhaust purifier.
Background technology:
Diesel engine is rapid at automobile industry development because of advantages such as its power are sufficient, fuel efficiency is high, it is little to take up room, durability is strong, but the NOx that diesel engine is discharged is about petrolic 2-20 times, the PM discharged is about petrolic 10-100 times, and environment is caused severe contamination.The strictest along with exhaust gas from diesel vehicle Abgasgesetz, while engine technology is optimized, exhaust gas from diesel vehicle post-processing technology obtains society's extensive concern, becomes the focus in post-processing technology and difficulties especially about purification vehicle exhaust under cryogenic conditions in recent years.It is applied on diesel vehicle according to up-to-date purification standard, SCR (SCR) system and particulates in exhaust gas from diesel vehicle catcher (DPF).But SCR system exists use, and temperature range is little, ammonia easily leaks, catalyst is easily poisoned, take up room big and high in cost of production problem；There is difficulty low, renewable to nanoscale PM arresting efficiency in DPF, back pressure is high and oil product is required the problems such as high.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of purifier for tail gas of diesel truck, and the technical scheme of employing is as follows:
Automobile exhaust purifier, including gas inlet, offgas outlet and rustless steel cylinder, gas inlet is connected with rustless steel cylinder, rustless steel cylinder is connected with offgas outlet, rustless steel cylinder is provided with wood fiber filter element, it is in close contact between wood fiber filter element and rustless steel cylinder, it is provided with small sircle hole in the middle of wood fiber filter element, the outer wall of rustless steel cylinder is provided with insulating plug, insulating plug is provided with electrode wires, one end of electrode wires is connected with external power source positive pole by insulating plug, electrode wires be shaped as " L " type, the other end of electrode wires is located in the small sircle hole in the middle of wood fiber filter element.The wood fiber has natural loose structure and to PM filter efficiency advantages of higher.Lower temperature plasma technology is widely regarded as the most promising post-processing technology, being combined with catalyst and can improve the efficiency of purifying contaminated thing and purify reaction selectivity, many researchs are all attempted increasing lower temperature plasma technology in post-processing technology to improve purification efficiency.
Preferably: in order to preferably improve the stability of product, the right of rustless steel cylinder is provided with supporting and mounting bracket one, the left end of rustless steel cylinder is provided with supporting and mounting bracket two, supporting and mounting bracket two is connected with left end and the right-hand member of wood fiber filter element respectively with supporting and mounting bracket one, and electrode wires is connected with bracing frame.
Beneficial effects of the present invention: good purification, low cost, oil product is required low, back pressure is little and security and stability high, is widely used, and is suitable to popularize in an all-round way and application.
Accompanying drawing explanation
Fig. 1 this utility model automobile exhaust purifier structural representation.
Detailed description of the invention
In order to make those skilled in the art be more fully understood that the technical solution of the utility model, it is described in further detail below in conjunction with the accompanying drawings and in conjunction with the embodiments to the technical solution of the utility model.
Embodiment 1
nullAutomobile exhaust purifier，Including gas inlet 1、Offgas outlet 7 and rustless steel cylinder 2，Gas inlet 1 is connected with rustless steel cylinder 2，Rustless steel cylinder 2 is connected with offgas outlet 7，Rustless steel cylinder 2 is provided with wood fiber filter element 6，Space is not left between wood fiber filter element 6 and rustless steel cylinder 2，It is provided with small sircle hole in the middle of wood fiber filter element 6，The outer wall of rustless steel cylinder 2 is provided with insulating plug 5，Insulating plug 5 is provided with electrode wires 4，One end of electrode wires 4 is connected with external power source positive pole by insulating plug 5，Electrode wires 4 be shaped as " L " type，The other end of electrode wires 4 is located in the small sircle hole in the middle of wood fiber filter element 6，The right of rustless steel cylinder 2 is provided with supporting and mounting bracket 1，The left end of rustless steel cylinder 2 is provided with supporting and mounting bracket 23，Supporting and mounting bracket 23 is connected with left end and the right-hand member of wood fiber filter element 6 respectively with supporting and mounting bracket 1，Electrode wires 4 is connected with bracing frame 9.The when of use, it is connected in high voltage power supply by electrode wires 4, gas molecule can be ionized to as the most active free radical of chemical property and the form of ion isoreactivity particle, such as free radicals such as OH, O and N0, PM can be trapped by wood fiber filter element 6 simultaneously, under the catalytic action of catalyst cerium oxide, a part of PM can be oxidized to CO or CO by the active particle with oxidisability2, a part of NOx can be reduced to N by being reduced property particle2, the oxidation of PM and the reduction of NOx are mutually promoted.After certain clarification time, relatively clean tail gas enters air from outlet 7.Wood fiber filter element 6, as discharge medium, provides carrier for catalyst simultaneously, improves the heat stability of catalyst, it is ensured that surface availability of catalyst amasss.
The above, preferred embodiment the most of the present utility model, not this utility model is made any pro forma restriction；The those of ordinary skill of all industry all can shown in by specification accompanying drawing and the above and implement this utility model swimmingly；But; all those skilled in the art are in the range of without departing from technical solution of the present invention; the a little change that may utilize disclosed above technology contents and make, the equivalent variations modified and develop, within all still falling within the protection domain of the technical solution of the utility model.
