Description

Technical Field

[0001] The utility model relates to the technical field of diesel engine DPF circulation cleaning and regeneration, and more specifically, to diesel engine DPF circulation cleaning and regeneration equipment. Background Art

[0002] Under current technical conditions, the DPF (diesel particulate filter) cycle cleaning and regeneration equipment of diesel engines is an important auxiliary tool to ensure that diesel engine emissions meet standards. During operation, this type of equipment needs to finely filter the diesel to remove impurities and particulate matter that may damage the DPF. However, the existing DPF cleaning and regeneration equipment faces the problem of inconvenient filter replacement after long-term continuous use. This is because the filter will accumulate a large amount of impurities during long-term use, resulting in a decrease in filtration efficiency, and eventually needs to be replaced to maintain the normal operation of the equipment.

[0003] In response to this problem, the existing equipment design does not fully consider the convenient replacement of the filter. After the equipment has been used for a period of time, the replacement process becomes complicated and time-consuming due to the close connection between the filter and other parts of the equipment. This not only increases maintenance costs, but may also affect production efficiency and continuous operation of the equipment due to downtime during the replacement process. In addition, the complex replacement process may also pose a potential threat to the safety of operators. Therefore, how to improve the filter replacement method of existing equipment to make it more convenient and safe has become an important part of improving the performance of DPF circulation cleaning and regeneration equipment.
