Description

Technical Field

[0002] A diesel generator is a type of power generation equipment, which refers to a power machine that uses diesel as fuel and a diesel engine as the prime mover to drive the generator to generate electricity. The whole unit is generally composed of a diesel engine, a generator, a control box, a fuel tank, a storage battery for starting and control, a protective device, an emergency cabinet and other components. A small amount of exhaust gas is discharged during the use of the diesel generator. If this exhaust gas is directly discharged, it will cause certain pollution to the surrounding environment. The main components of the exhaust gas are dust and nitrogen oxides. The current common purification device usually filters the dust in the exhaust gas, and then centrally neutralizes the exhaust gas, and the purification efficiency is low.

[0003] CN202120872303.8 introduces an energy-saving exhaust gas purification device for a diesel generator set, which passes the gas discharged from the generator set into a filter box, undergoes preliminary filtration with water to precipitate particulate matter, and then passes through an activated carbon filter, and further adsorbs and filters the remaining particulate matter in the gas. The gas then enters a drum and is adsorbed and filtered through a zeolite molecular sieve, and clean gas is discharged to reduce pollution to the environment. However, in the process of purifying the exhaust gas, the exhaust gas purification device has a high temperature when the exhaust gas is discharged, and the impurities inside it are easy to move quickly at high temperature, which is not conducive to the aggregation of impurities, and the purification efficiency is low.
