An exhaust gas treatment device, comprises a housing having an exhaust gas inlet 1 and a plurality of stages of energy-exchanging units 2 arranged in a row within the housing. Each energy-exchanging unit 2 comprises a jet flow nozzle 21, an associated diffusion bore 22 and an energy-exchanging chamber 23 coupled therebetween. The energy-exchanging chamber 23 of the first stage of the energy-exchanging units 2 is provided with an opening 24 leading to ambient atmosphere surrounding the housing. A gas-mixing chamber 3 is provided between two adjacent stages of the energy-exchanging units 2, respectively. A recirculating tube 4 is connected between the gas-mixing chamber 3 of the second through last stages of the energy-exchanging units 2 and the gas inlet of the first stage of the energy-exchanging units (2), respectively. |
