Description

Diesel generator set Technical Field The invention relates to the technical field of diesel generators, in particular to a diesel generator set. Background The cylinder sleeve cooling liquid is high-temperature cooling liquid for taking heat of the cylinder wall when the diesel generating set operates, the outlet temperature is kept at 80-95 ℃ throughout the year, the flow is large, the heat capacity is stable, and the cylinder sleeve cooling liquid is a low-temperature waste heat source with highest grade and easy recovery. The recovery process of the cylinder liner cooling liquid is very mature, and the cylinder liner cooling liquid can be utilized in four stages of heat exchange, refrigeration, power generation and heat storage, wherein equipment which is frequently adopted in heat exchange is a tubular heat exchanger or a plate heat exchanger, and necessary filtering work is needed in heat exchange so as to eliminate impurities in the cylinder liner cooling liquid and prevent the heat exchange efficiency of the heat exchanger from being reduced due to scaling phenomenon of the impurities in the heat exchange process. In the filtering process, impurities adhere to one side of the filter screen plate along with the filtering, so that the permeability and the filterability of the filter screen plate are reduced. The traditional practice is to set up the round brush at the filtration side of filter screen board, clear away impurity through the round brush. The impurity on the filter screen plate can be removed through the mode, but the impurity can be transferred to the rolling brush, and the impurity on the rolling brush is brought to the filter screen plate again when the cylinder sleeve cooling liquid flows again, so that the permeability and the filterability of the filter screen plate can be rapidly reduced in a short time, and the operation of equipment is affected.
