Embodiment Construction

[0042] See Figure 4. The diesel engine exhaust infrared purification device of the present invention is made of a honeycomb heating purifier 3, and this honeycomb heating purifier comprises an intake pipe end cover 31, an exhaust pipe end cover 32 and is connected to the intake pipe end cover, The shell formed by the annular cylinder 33 between the end caps of the exhaust pipe, the two sides of the cylinder are respectively provided with a filter screen 34 and a porous plate 35 sequentially from the outside to the inside, and a cavity is formed in the middle, and in the cavity (between the two porous plates ) is densely filled with infrared spheres 36; a buffer net 37 behind the perforated plate at the intake end side, and two layers of catching filter screens 38 arranged at intervals in the cylinder. The structure traps particles in the direction of axial flow.

[0043] See Figure 5. The buffer net 37 of the present invention has a diameter smaller than that of the perforat...

Abstract

It relates to a diesel engine exhaust infrared purification device and method, with the device composed of the barrel shell, filtering net and multi porous outside to the inside from both sides of the barrel, middle of the multi porous plates stuffed with infrared ball, buffer net at the rear of the multi porous plate at the air inlet end, and at least a layer of filtering net inside the barrel. It features in the air outlet of the engine connected to the input of the cellular heating purifier whose output connects to the exhaust manifold of the engine. In application, using the exhaust heat of the compression internal combustion, it heats the vertical cellular structure quickly to 650deg.C-800deg.C ignition temperature with infrared material tightly stuffed, allowing particles attached to the spherical surface of and filtered net surface to achieve the goal of quick oxidation and purification to the particles. It can effectively purify the poisonous emitted pollutants in the exhaust gas.

Description

technical field [0001] The invention relates to a device for automatic circulation and regeneration of diesel engine exhaust gas, in particular to a diesel engine exhaust infrared purification device and a purification method thereof. Background technique [0002] So far, the most widely used diesel engine exhaust post-treatment technology in the world is the particulate filter using cordierite as the main raw material. This particulate filter has a high filtration efficiency for soot. However, the particle filter can only filter the particles from the exhaust of the diesel engine and deposit them in the wall of the hole. Cause exhaust back pressure to increase, affect the gas exchange charge of the diesel engine, the power drops sharply, the fuel consumption increases, the combustion deteriorates, and the emission pollution is more serious. [0003] Therefore, it is necessary to remove the particles in the particle filter in time so that it can continue to work. Removing ...
