Embodiment 1

[0049] see Figure 1-Figure 3 , a kind of automobile exhaust emission filter device with automatic cleaning function, comprises treatment box 1, and the right side of treatment box 1 is fixedly installed with the connection pipe 2 that is used for being connected with automobile exhaust pipe, is used for leading into automobile exhaust, and treatment box 1 A stopper 3 is arranged inside the stopper 3, and a heat conduction block 4 is arranged on the side of the stopper 3 facing the connecting pipe 2. The left end of the heat conduction block 4 is fixedly installed with a heat conduction rod 5, and the end of the heat conduction rod 5 is fixedly connected with a resistance wire 6. The processing box 1 The left side of the inner wall is fixed with an arc-shaped plate 7, and a combustion chamber is formed between the arc-shaped plate 7 and the stopper 3, and the resistance wire 6 traverses the interior of the combustion chamber;

[0050] The high-temperature automobile exhaust ga...

Embodiment 2

[0055] see Figure 4-Figure 6 , on the basis of Embodiment 1, an air pump 9 is fixedly installed on the top and bottom of the right end of the processing box 1, the output ends of the two air pumps 9 are fixedly installed with an air supply pipe 10, and the ends of the two air supply pipes 10 are connected through Distribution pipe 11, two distribution pipes 11 are respectively arranged between the top of the right end of the block 3 and the inner side wall of the treatment box 1 and between the bottom of the right end of the block 3 and the inner side wall of the treatment box 1, the oxygen contained in the automobile exhaust The amount is low, and it is difficult to realize the full combustion of hydrocarbons and hydrocarbons. At this time, new air can be added through the air pump 9;

[0056] The air pump 9 runs through the air supply pipe 10, the distribution pipe 11 and the nozzle 12 to discharge air, and the discharged air is mixed with the automobile exhaust gas to incr...

Embodiment 3

[0061] see Figure 7-Figure 9 , on the basis of Embodiment 1 and Embodiment 2, the end of the air outlet pipe 8 is fixedly installed on the left side of the filter cartridge 14, and the filter cartridge 14 is fixedly installed on the bottom of the processing box 1 and communicated with the combustion chamber. The right side is fixedly equipped with an exhaust pipe 15, and the air outlet pipe 8 and the exhaust pipe 15 are all connected with the filter cartridge 14;

[0062] The interior of the filter cartridge 14 is provided with a plunger 16, and the interior of the plunger 16 is horizontally penetrated with a communication groove 17. The communication position of the outlet pipe 8 and the exhaust pipe 15 on the filter cartridge 14 corresponds to the opening position of the communication groove 17. , the interior of the communication groove 17 is relatively provided with two clamping nets 22, and a filter core 23 is filled between the two clamping nets 22. In this embodiment, ...

Abstract

The invention relates to the technical field of automobile tail gas treatment, and discloses an automobile tail gas discharging and filtering device with an automatic cleaning function. A treatment box is included, a connecting pipe used for being connected with an automobile tail gas pipe is fixedly mounted on the right side of the treatment box, and a stop block is arranged in the treatment box. A heat conduction block is arranged on the side, facing the connecting pipe, of the stop block, a heat conduction rod is fixedly installed at the left end of the heat conduction block, and a resistance wire is fixedly connected to the tail end of the heat conduction rod. High-temperature automobile tail gas exhausted by an automobile enters a combustion chamber through the connecting pipe, heat transfer occurs between the automobile tail gas and the resistance wire through the heat conduction block and the heat conduction rod, the temperature of the resistance wire is gradually increased, and when the temperature of the resistance wire reaches the ignition point of the automobile tail gas, the automobile tail gas in the combustion chamber can be ignited; and the automobile tail gas is subjected to secondary combustion, harmful substances in the automobile tail gas are effectively eliminated, and an excellent purification treatment effect is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust gas treatment, in particular to an automobile exhaust emission filter device with automatic cleaning function. Background technique [0002] With the development of science and technology and the gradual improvement of people's living standards, there are more and more cars, which have gradually become a necessary travel tool for every family; however, with the increase in the use of cars, the pollution caused by car exhaust is also increasing. It is getting more and more serious; the tail gas emitted by automobiles contains nitrogen, carbon monoxide, carbon dioxide, unburned hydrocarbons, carbon nitrogen compounds, nitrogen oxides and sulfur dioxide and other gases harmful to the environment and human body, which will not only cause serious pollution to the environment , there is also a lot of damage to human health, so how to effectively reduce the pollution of automobile exhaust is a...
