Description

Diesel particulate matter trap burning purifier

Technical Field

The utility model relates to the technical field of waste gas treatment, in particular to a combustion purification device of a diesel particulate matter catcher.

Background

Pollution of diesel engines comes primarily from three areas-particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur. Wherein the particulate emissions (soot) consist mostly of carbon or carbide micro-particles (size less than 4-20 μm); since exhaust gas contains a large amount of particulate emissions, hydrocarbons (HCx), nitrogen oxides (NOx), and sulfur, which cause pollution, it is necessary to purify the exhaust gas during the exhaust process.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the defects in the prior art and provides a combustion purification device of a diesel particulate filter.

In order to achieve the purpose, the utility model adopts the following technical scheme:

a combustion purification device of a diesel particulate filter comprises a shell and a combustion chamber arranged in the shell, wherein two ends of the shell are respectively connected with a flue and a discharge flue, two opposite inner walls of the combustion chamber are respectively provided with a combustion head, and the combustion heads positioned on different sides are arranged in a staggered manner;

the inner wall of the combustion chamber is connected with a plurality of clapboards which are arranged in parallel with the upper wall and the lower wall of the shell.

Preferably, the top and the bottom of the shell are respectively connected with an upper lattice and a lower lattice in one-to-one correspondence.

Preferably, the flue and the flue far away from one side of the shell are respectively connected with a flue flange and a connecting flange in a one-to-one correspondence manner.

Preferably, a waterproof cover is covered above the combustion head and connected with the shell.

Preferably, the side wall of the discharge flue is connected with a cross fixing frame.

Compared with the prior art, the utility model has the beneficial effects that: the waste gas burner has a simple structure, waste gas enters the combustion chamber through the flue, the flame is sprayed out from the combustion head to combust the waste gas, and the staggered combustion heads can combust the waste gas for multiple times, improve the exhaust temperature, facilitate later catalytic reaction, gasify and burn part of the leaked engine oil, and simultaneously burn part of carbon particles and part of insufficiently combusted diesel oil to ensure that the diesel oil is fully combusted.

In the figure: the device comprises a shell 1, a flue 2, a flue flange 3, a cross fixing frame 4, a connecting flange 5, a lower grid 6, an upper grid 7, a waterproof cover 8, a discharge flue 9, a combustion head 10 and a combustion chamber 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-5, a combustion purification device of a diesel particulate filter comprises a shell 1 and a combustion chamber 11 arranged inside the shell, wherein two ends of the shell 1 are respectively connected with a flue 2 and a discharge flue 9, two opposite inner walls of the combustion chamber 11 are respectively provided with a combustion head 10, the combustion heads 10 positioned on different sides are arranged in a staggered manner, and through the staggered combustion heads 10, multiple combustion can be performed on waste gas, so that the exhaust temperature is raised, part of engine oil which is blown out is gasified and burnt, and part of carbon particles and part of diesel oil which is not fully combusted are burnt simultaneously, so that the diesel oil is fully combusted;

the inner wall of the combustion chamber 11 is connected with a plurality of clapboards which are arranged in parallel with the upper wall and the lower wall of the shell 1, the waste gas is separated in a layered mode and then is combusted in a layered mode, and the phenomenon that series flow occurs to cause insufficient combustion is avoided.

In this embodiment, the top and the bottom of the housing 1 are respectively connected with the upper lattice 7 and the lower lattice 6 in one-to-one correspondence, and the strength of the housing 1 is enhanced by the upper lattice 7 and the lower lattice 6.

In the embodiment, the flue 2 and the flue 9 are respectively connected with the flue flange 3 and the connecting flange 5 in one-to-one correspondence on the sides far away from the shell 1, and are respectively used for connecting with the flue and the catalytic chamber.

In this embodiment, the top cover of burner 10 is equipped with waterproof cover 8, and waterproof cover 8 is connected with casing 1, improves burner 10 waterproof ability, and the lateral wall of discharge flue 9 is connected with cross mount 4, promotes the intensity of discharge flue 9.

In the present case, waste gas passes through flue 2 and gets into combustion chamber 11, and burning head 10 blowout flame burns it, through the burning head 10 that staggers the setting, can carry out a lot of burning through waste gas, promotes exhaust temperature, makes things convenient for the later stage to carry out catalytic reaction, and the engine oil that the part was scurried out is burnt simultaneously with burning off the diesel oil of partial carbon granule and partial insufficient combustion, makes its abundant burning.
