The invention discloses a flue gas desulphurization waste liquid spray drying treatment apparatus and a treatment method thereof. The apparatus comprises a spray drying tower, the gas inlet of the spray drying tower is connected with a gas inlet flue, the inlet of the gas inlet flue communicates with the upstream or the midstream of the main flue of a boiler to shunt hot flue gas in the main flue of the boiler, the gas outlet of the spray drying tower is connected with a gas outlet flue, the outlet of the gas outlet flue communicates with the downstream of the main flue of the boiler to send the hot flue gas to the main flue of the boiler, a desulphurization waste liquid atomizer is arranged in the top of the spray drying tower, and the inlet of the desulphurization waste liquid atomizer is connected with a desulphurization waste liquid inlet tube. The apparatus and the method have the following advantages: the shunted hot flue gas of the boiler is adopted as a heat source, and exchanges heat with fine mist formed through atomizing a desulphurization waste liquid by the desulphurization waste liquid atomizer in the spray drying tower to make the fine mist of the desulphurization waste liquid be rapidly dried in order to form fine powder, so the desulphurization waste liquid is thoroughly eliminated without fouling or corrosion of the main flue of the boiler or a deduster.

An exhaust gas purification apparatus for diesel engine that is enhanced in NOx purification performance and PM purification performance. There is provided an exhaust gas purification apparatus comprising upstream catalyst (3) of straight flow structure carrying a first NOx occluding material capable of effectively occluding NOx in a low temperature region and carrying a noble metal; midstream catalyst (4) of straight flow structure carrying a second NOx occluding material capable of effectively occluding NOx in an intermediate temperature region and carrying a noble metal; and downstream catalyst (5) of wall flow structure carrying a third NOx occluding material capable of effectively occluding NOx in a high temperature region and carrying a noble metal.
