Abstract

The invention relates to a filtering device, in particular to an automobile exhaust filtering device. The automobile exhaust filtering device comprises a pipe body. One end of the pipe body is provided with an air inlet, and the other end of the pipe body is provided with an air outlet. At least one level of filtering element is installed in the pipe body, wherein the filtering element is in a cylinder shape and is provided with a plurality of axially-arranged channels. By means of the automobile exhaust filtering device, due to the fact that the pipe body connected with an exhaust pipe of an automobile engine is arranged, at least one level of filtering element is installed in the pipe body, and each filtering element is provided with the multiple axially-distributed channels, automobile exhaust can be filtered to a certain degree before being exhausted into the atmospheric environment, and pollutants contained in the automobile exhaust are effectively reduced.

Description

Automobile tail gas filtering device
Technical field
The present invention relates to a kind of filtration unit, particularly relate to a kind of automobile tail gas filtering device.
Background technology
The tail gas of automobile is present stage one of source of pollution of worsening of urban air, is also one of factor aggravating atmospheric warming effect in recent years, and therefore, the discharge reducing pollutent in vehicle exhaust is the content can not ignore in Environment control process. Automobile tail gas filtering device can obviously reduce the pollutant load in vehicle exhaust, but existing filtration unit production cost and use cost are all very high, and car manufactures and consumers in general are not easy to accept.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide and a kind of can effectively reduce pollutant load in vehicle exhaust and the low automobile tail gas filtering device of cost.
For solving the problems of the technologies described above, the automobile tail gas filtering device of the present invention, it comprises a pipe body, one end of described pipe body is inlet mouth, the other end is air outlet, is provided with at least one-level filtration core in described pipe body, and described filtration core is column and is distributed with multiple passage arranged vertically.
It is nested with a protective sleeve in the outside of described pipe body.
A screw thread inner sleeve it is threaded connection respectively at the inlet mouth of described pipe body and the inner side of air outlet.
Described filtration core adopt active carbon powder, natural zeolite powder, active oxidation aluminium powder form, limestone powder, sodium hydroxide powder, silicon sol in proportion 0.2:1:1:1:1:0.5 mix after through compacting, High Temperature Furnaces Heating Apparatus fired.
At described Guan Tizhong, three grades of described filtration core are set.
The present invention is owing to adopting above technical scheme, therefore following technique effect can be obtained: 1, the present invention is owing to being provided with a pipe body being connected with automobile engine exhaust pipe, at least single filter core is installed in pipe body, each filtration core is provided with multiple passage distributed vertically, therefore, vehicle exhaust is before being disposed to atmospheric environment, it is possible to through filtration to a certain degree, effectively reduces pollutent contained in vehicle exhaust. 2, the present invention is owing to having protective sleeve in the outer setting of pipe body, therefore, it is possible to pipe body is formed protection, extends work-ing life. 3, present configuration is simple, cost is low, is easy to promote.
Accompanying drawing explanation
Fig. 1 is the front view of the present invention;
Fig. 2 is the side-view of the present invention;
Fig. 3 is the sectional view of the present invention;
Fig. 4 is the schematic diagram of present tube body.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figures 1 to 3, the automobile tail gas filtering device of the present invention, comprises a pipe body 1, and one end of pipe body 1 is inlet mouth, and for connecting automobile engine vapor pipe, the other end of pipe body 1 is air outlet, for connecting automotive muffler. Being provided with at least one-level filtration core 2 in pipe body 1, filtration core 2 is in column and is distributed with multiple passage 21 arranged vertically.
Further, a protective sleeve 3 it is nested with in the outside of pipe body 1.
Further, as shown in Figure 4, being threaded connection a screw thread inner sleeve 4 respectively at the inlet mouth of pipe body 1 and the inner side of air outlet, the effect of screw thread inner sleeve 4 prevents filtration core 2 from skidding off pipe body 1, screw thread inner sleeve 4 is convenient to installation and removal simultaneously, thus is convenient to change filtration core 2.
Further, filtration core 2 adopt active carbon powder, natural zeolite powder, active oxidation aluminium powder form, limestone powder, sodium hydroxide powder, silicon sol in proportion 0.2:1:1:1:1:0.5 mix after through compacting, High Temperature Furnaces Heating Apparatus fired, firing temperature is 700 DEG C.
Further, pipe body 1 arranges three-stage filtration core 2, an every one-level filtration core 2 i.e. filtration core 2.
Obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments. Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
