Abstract
The utility model discloses a mixer for a marine selective catalytic reduction emission reduction system, which comprises an evaporating section, wherein a mixing section is arranged behind the evaporating section; a fume inlet and a reducing agent injecting inlet are arranged before the evaporating section; and a turbulence device is arranged in the mixing section. The utility model has reasonable structure, the fume and the reducing agent can be mixed evenly, and the working performance of the marine selective catalytic reduction emission reduction system can be effectively improved.
Description
Technical field:
The utility model relates to a kind of ship selective catalytic reduction emission-reducing system mixer.
Background technique:
The pollution of atmosphere that is caused by boats and ships is to the stage that can not ignore, bringing day by day for boats and ships internal environment and external environment condition seriously influences, particularly at the harbour, straits and some course lines are intensive, the boats and ships flow is big sea area, the primary pollution source of boats and ships exhaust gas discharged or even this area.
The reduction of discharging of marine exhaust NOx, International Maritime Organization IMO has proposed the requirement of three phases to all flag countrys.Come into effect the NOx discharging from 2011 and be the regulation of Tier II limit value, to carry out the NOx discharging by 2016 and be the regulation of Tier III limit value, because the NOx limit value of Tier III regulation is that the technological improvement institute of motor itself is irrealizable, and all NOx reduction of discharging measures have only engine exhaust after-treatment device SCR can realize the limit value regulation of Tier III.
Existing ship selective catalytic reduction emission-reducing system, the mixing uniformity of flue gas and reducing agent is undesirable, influences service behaviour.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the ship selective catalytic reduction emission-reducing system mixer that flue gas and reducing agent are mixed.
Technical solution of the present utility model is:
A kind of ship selective catalytic reduction emission-reducing system mixer is characterized in that: comprise evaporator section, mixing section is set behind the evaporator section, before the evaporator section flue gas inlet is set and injection of reducing agent injects mouth, in the mixing section disturbing flow device is set.
Injection of reducing agent injects mouth and is connected with reducing agent injector.
The utility model is rational in infrastructure, and flue gas and reducing agent are mixed, and effectively improves the service behaviour of ship selective catalytic reduction emission-reducing system.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of ship selective catalytic reduction emission-reducing system mixer comprises evaporator section 1, and mixing section 2 is set behind the evaporator section, flue gas inlet 3 and injection of reducing agent is set before the evaporator section injects mouth, and disturbing flow device 5 is set in the mixing section.Injection of reducing agent injects mouth and is connected with reducing agent injector 4.
Claims (2)
1. ship selective catalytic reduction emission-reducing system mixer is characterized in that: comprise evaporator section, mixing section is set behind the evaporator section, before the evaporator section flue gas inlet is set and injection of reducing agent injects mouth, in the mixing section disturbing flow device is set.
2. ship selective catalytic reduction emission-reducing system mixer according to claim 1 is characterized in that: injection of reducing agent injects mouth and is connected with reducing agent injector.
