Description

A car exhaust pipe with a filter element

technical field

The utility model relates to automobile components, in particular to an automobile exhaust pipe, in particular to an exhaust pipe for reducing the discharge of harmful substances in tail gas.

Background technique

At present, automobile exhaust is directly discharged from the rear muffler pipe, and the insufficiently treated exhaust gas also contains a large amount of harmful substances, which seriously pollutes the air.

This problem has become the primary problem of China's air pollution, so reducing vehicle exhaust emissions is an urgent problem to be solved.

Although the technologies of many Chinese patent applications relate to reducing the emission of harmful substances in automobile exhaust, none of them have solved the problem ideally.

Contents of the invention

The purpose of the utility model is to provide an automobile exhaust pipe with a filter element in view of the deficiencies in the prior art. The automobile exhaust pipe with a filter element is easy to replace and clean.

In order to achieve the above design purpose, the utility model is realized through the following technical solutions.

Design and manufacture a car exhaust pipe with a filter element, including: an air intake pipe, and a filter element cavity connected between an air outlet pipe;

A filter element is arranged in the filter element chamber; a fan is arranged in the air intake duct, a fan motor is installed outside the air intake duct, and the fan and the fan motor are meshed through bevel gears.

The filter element cavity is provided with a filter element bin door.

The diameter of the filter element is smaller than the inner diameter of the filter element cavity.

The filter element is placed in multiple sections in the filter element cavity, and many pores are distributed in each section of the filter element, and the diameter of each hole is less than 500nm.

The structure of the filter element includes: an activated carbon filter element and a filter cotton filter element.

Many pores are distributed in the filter core, and the pores are arranged horizontally.

Compared with the prior art, the filter core of the utility model is easy to replace and clean. In order to make the tail gas discharge smoothly, the utility model is equipped with a fan to increase the pressure of the exhaust gas to be discharged outward. The filter element warehouse of the utility model has a filter element door design, which can conveniently replace the filter element and clean the filter element, so that the filter element can be used repeatedly and reduce costs. , the utility model has a good emission reduction effect.

Description of drawings

The utility model is further described below using the drawings, but the embodiments in the drawings do not constitute any limitation to the utility model.

Fig. 1 is the schematic diagram of the automobile exhaust pipe that the utility model adds filter element.

Detailed ways

The utility model will be described below in conjunction with specific embodiments.

As shown in Figure 1, a kind of automobile exhaust pipe that adds filter element comprises: an air intake pipe 6, connects filter element chamber 1 between an air outlet pipe 7; A filter element 2 is arranged among the filter element chamber 1; A fan 5 It is arranged inside the air intake pipe 6 , and a fan motor 3 is installed outside the air intake pipe 6 , and the fan 5 and the fan motor 3 are meshed through the bevel gear 4 .

The filter element cavity 1 is provided with a filter element compartment door 12 .

The diameter of the filter element 2 is smaller than the inner diameter of the filter element chamber 1 .

The filter element 2 is placed in multiple sections in the filter element cavity 1, and each section of the filter element 2 is distributed with many fine pores, and the diameter of each hole is less than 500nm.

The structure of the filter element 2 includes: an activated carbon filter element and a filter cotton filter element.

Many pores are distributed in the filter element 2, and the pores are arranged horizontally.

In the figure, the setting of the bevel gear 4 is to prevent the fan motor 3 from being quickly damaged by the high temperature of the exhaust gas, so that the fan motor 3 is moved out of the intake pipe 6 .

Since the first filter element 2 in the filter element compartment 1 is blocked first, the filter element compartment door 12 can be opened to take out the filter element 2. After cleaning, move the second filter element 2 to the left, and put the cleaned filter element 2 at the bottom. last.

The utility model not only can adopt the filter core 2 of multiple structures, as active carbon filter core, filter cotton filter core or the like. The replacement of the filter element 2 of the utility model is very convenient, and the polluted substances after cleaning are processed with the cleaning water, and will not enter the atmosphere again.

The utility model has long service life and low cost, and the utility model has good emission reduction effect.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
