Abstract
The utility model discloses a vehicle exhaust sound absorbing filter which comprises an exhaust discharge pipe and a silencer. Compared with prior art, the vehicle exhaust sound absorbing filter is characterized in that the silencer is divided into a first spray processing chamber, a second spray processing chamber and a filtering chamber which are independent relatively and are sequentially connected with a sealing ring. Each spray processing chamber is equally provided with a nozzle, a sound absorbing pipe and a gas chamber. A permanent magnet is provided outside the silencer corresponding with the spray processing chamber. Filtering material is filled in the filtering chamber. The vehicle body outside the silencer is provided with a liquid box, a pressure pump and a controller of pump. The pressure pump is communicated with the liquid box and the nozzles installed in the first spray processing chamber and the second spray processing chamber through pipe. The first spray processing chamber, the second spray processing chamber and the filtering chamber are communicated through sound absorbing pipe. The filter element of filtering material is sponge. The solution in the liquid box is saturated Ca(OH)2 solution. The vehicle exhaust sound absorbing filter of the utility model can effectively reduce the discharge of harmful material in the exhaust to the atmosphere. Furthermore the vehicle exhaust sound absorbing filter of the utility model has the advantages of easy manufacture of device, low fabricating cost, easy filter element cleaning and replacing, and available processing liquid.
Description
Technical field
The utility model relates to automobile exhaust gas purifying installation, especially automobile tail gas noise elimination collecting filter.
Background technique
The exhaust emission of automobile, the nitrogen in the deacration, oxygen, water vapour are that all the other are harmful components outside the harmless composition.A part of toxicant in the motor car engine discharge tail gas causes because fuel combustion is incomplete or fuel gas temperature is low, and is especially at order starting, oil sprayer atomization badness, particularly serious during the overwork operation.Simultaneously, fuel oil can not fully burn with oxygen well, generates a large amount of carbon monoxide (CO), hydrocarbon (HC) and soot particulate, and another part Toxic is because the nitrogen oxide type gas NO of the high temperature in the firing chamber, high pressure formation
X(NO, NO
2And NO
XGeneral name).
CO in the tail gas of motor vehicle emission, HC compound, NO
XAll be harmful material, in addition, carbon dioxide (CO
2) can cause " greenhouse effect ", also having lead compound, sulfur compounds etc. also is harmful components.
Along with the development of society and the raising of people's living standard, automobile enters ordinary family just at a terrific speed, and rolling up of automobile quantity makes the emission of automobile wastes thing, has brought serious pollution for human life and living environment.
Present vent gas treatment technology adopts the catalytic purification scheme, and effect is better, but noble metal catalyst and production, user cost are higher, filter core is changed inconvenience; Employing is installed water box on the automobile exhaust tube, by its water tail gas implement is filtered, but because the punching press that vehicle exhaust is followed when discharging is very high, its water directly can be gone out, and can't well carry out tail gas filtering, and effect is relatively poor.
The model utility content
The purpose of this utility model is at the deficiencies in the prior art, provides that a kind of cost is low, that filter core is changed is convenient, filtering effect automobile tail gas noise elimination collecting filter preferably.
The utility model is achieved through the following technical solutions:
A kind of automobile tail gas noise elimination collecting filter, comprise exhaust pipe and silencing apparatus, unlike the prior art be: silencing apparatus be divided into relatively independent with seal ring be linked in sequence first the spraying process chamber, second spraying process chamber and the filter chamber, each spraying process chamber is equipped with nozzle, hush tube and air chamber, the silencing apparatus outside of spraying process chamber correspondence is provided with permanent magnet, fill filtering material in the filter chamber, the outer car body of silencing apparatus is provided with the liquid case, the control gear of pressure pump and pump, pressure pump is with pipeline and liquid case and be arranged on first, the nozzle of the second spraying process chamber is communicated with first, the second spraying process chamber and filter chamber are communicated with by hush tube.
Described filtering material filter core is a sponge.
Be respectively arranged with friction resistant material between the air chamber of described first, second spraying process chamber and the inwall of silencing apparatus.
Solution in the described liquid case is saturated Ca (OH)
2Solution.
Working principle of the present utility model is: 1, pressure pump and nozzle combination, with the atomizing of the treatment fluid in the liquid case, make it fully to mix with tail gas, and tail gas is played cleaning function; 2, form under the strong magnetic field action at permanent magnet, part harmful matter in the tail gas and the reaction of the treatment fluid in the liquid case have attenuation to tail gas, for example: CO
2+ Ca (OH)
2=CaCO
3↓+H
2O makes CO
2Be converted into harmless calcium carbonate; 3, the filter chamber is set, filtering material has absorption, filtration to harmful matter in the tail gas, reduces the discharging of soot.
Good effect of the present utility model is: can effectively reduce hazardous emission in the tail gas to atmosphere, and the device preparation easily, cost is low, cleans and more renew cartridge is easy, and treatment fluid is easy to get.
