Diesel engine exhaust purifier with rotary regeneration device

Abstract

The invention discloses a diesel engine tail gas purifier with a rotary regeneration device. The diesel engine tail gas purifier comprises a diesel engine tail gas purifier body, a regeneration nozzle and a regenerative catalytic device, wherein the regeneration nozzle is long, thin and linear and just faces to the rear end plane of the filter workpiece of the diesel engine tail gas purifier body, the nozzle is connected with a rotation mechanism and is driven by the rotation mechanism to slowly rotate; and the pressurized diesel engine tail gas passes through the regeneration nozzle to perform back flushing to each filtering channel of the filter workpiece and blows the soot particles deposited in the filter workpiece to an oxidation catalysis device, and the soot particles flow to a later-stage purifier after processing. The device has a simple structure, is reliable in operation, can realize complete regeneration and can also realize energy conservation and consumption reduction; and the filtration efficiency and regeneration efficiency are increased, the cost of the product is reduced, the purification performance of the tail gas purifier is increased, and the service life of the tail gas purifier is prolonged. By adopting the diesel engine tail gas purifier with a rotary regeneration device, the capture efficiency of the filter workpiece is increased to more than twice, which is increased by 100% compared with the traditional purifier; and the regeneration efficiency is up to 98%.

Description

technical field [0001] The invention relates to a technology and product for efficiently purifying or filtering (including regeneration) exhaust particulate matter of a diesel engine, in particular to a diesel engine tail gas purifier with a rotary regeneration device. Background technique [0002] After the diesel engine exhaust purifier is used for a period of time, soot particles will accumulate in the filter channel of the purifier and cause blockage, which will increase the back pressure of the diesel engine and reduce performance, so the purification filter needs to be regenerated. The traditional regeneration methods are mainly fuel oil heaters and electric heaters. These two devices have complex structures and require additional energy consumption, and the device cost is high, the use cost is high, and the regeneration efficiency is low; and when the device is regenerated, it cannot work in reverse at the same time. The purification efficiency is low. [0003] Chine...
