Problems solved by technology

However, the existing heating regeneration has more or less disadvantages, for example: the fuel injection heating regeneration cleaning method requires additional fuel and high cost; the ordinary electric heating regeneration cleaning method will cause uneven heating, which will lead to DPF The cleaning effect is poor, and causes local overheating and damage of the DPF; the microwave heating regenerative cleaning method needs to overcome the technical difficulty of how to excite as many modes as possible in the resonant cavity to achieve heating; the infrared heating device involved in the infrared heating regenerative cleaning method costs high
[0005] To sum up, the existing heating regeneration cleaning method is easy to damage the DPF, the cost of related equipment is high, and the related technology is immature, so it is impossible to clean the DPF efficiently and non-destructively at low cost, and the cleaning effect is poor

Abstract

The invention provides automatic cleaning equipment for a particle filter. The automatic cleaning equipment is used for heating and cleaning the particle filter. The automatic cleaning equipment is characterized by comprising a particle filter cleaning device and a control device, wherein the particle filter cleaning device is used for cleaning the particle filter; the control device is used for controlling the operation of the particle filter cleaning device; the particle filter cleaning device at least comprises a treatment temperature sensor which is used for sensing the temperature of air flow entering a cleaning chamber as a treatment temperature; and the control device controls an air inlet valve, a heating unit and an air flow driving unit based on the treatment temperature and a preset heating treatment curve, so that the treatment temperature accords with the preset heating treatment curve. The automatic cleaning equipment for the particle filter can quickly finish cleaning, has a good cleaning effect and does not damage the particle filter.

Description

technical field [0001] The invention belongs to the technical field of particle filter cleaning, and in particular relates to automatic cleaning equipment for particle filters. Background technique [0002] The exhaust system of a diesel vehicle includes an exhaust pipe and a particulate filter (Diesel Particulate Filter, DPF for short) installed in the exhaust pipe. When the exhaust gas in the exhaust pipe passes through the DPF, the particulate matter and oil in the exhaust gas are absorbed by the filter element of the DPF. filter. However, as the working time of the exhaust system of diesel vehicles increases, the particulate matter and oil pollution inside the DPF filter element also accumulates, resulting in an increase in the exhaust back pressure of the vehicle, an increase in the fuel consumption of the vehicle and a decrease in power. In addition, when the DPF filter element is severely clogged, the exhaust gas cannot be discharged. [0003] The conventional solut...
