Problems solved by technology

There are countless tiny holes in the DPF of this structure. With the use of the DPF, these tiny holes will be blocked by PM, and part of the PM will be oxidized and burned when the vehicle is running. With the increase of the working time of the DPF, such a method It is becoming more and more difficult to regenerate, and the DPF is seriously blocked and the exhaust gas cannot be discharged. At this time, a device that can clean the DPF is needed to dredge the tiny pores in the DPF

Abstract

Provided is an ultrasonic wave generator. The ultrasonic wave generator includes a vibrator head mounting box and an ultrasonic wave vibrator head fixed in the vibrator head mounting box. The ultrasonic wave vibrator head is contained in the vibrator head mounting box and fixed to a mounting box baseplate of the vibrator head mounting box, and the vibrator head mounting box is filled with an incompressible fluid. The vibrator head mounting box is provided with an adjusting port sealed by an elastic pressure balancing plate.

Description

technical field [0001] The invention relates to the field of ultrasonic waves, in particular to an ultrasonic generator. Background technique [0002] DPF, Diesel Particulate Filter refers to a device installed in the exhaust system of a diesel vehicle to reduce particulate matter (PM) in the exhaust by filtering, referred to as DPF. DPF can effectively purify 70% - 90% of the particles in the exhaust gas, and is one of the most effective and direct methods to purify diesel engine particulate matter. It has been commercialized internationally. The DPF is installed on the exhaust pipe of the diesel engine. When the exhaust gas passes through, the PM is adsorbed and filtered by the filter element. However, as the working time increases, the PM inside the filter element increases, resulting in an increase in the exhaust back pressure, which will affect the power and economy of the diesel engine. Removing PM from the filter element is called DPF regeneration. The biggest cha...
