Title:
REDUCING AGENT SUPPLY DEVICE AND EXHAUST PURIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/196346
Kind Code:
A1
Abstract:
Provided are a reducing agent supply device and an exhaust purification system with which it is possible to avoid problems such as breakdowns and malfunctions caused by thermal damage in a reducing agent injection valve, even when a cooling medium boils and vaporizes. An embodiment of a reducing agent supply device and an exhaust purification system according to the present invention is equipped with a cooling medium circulation device for cooling the reducing agent injection valve, and the inflow-side connecting part and the outflow-side connecting part of a cooling medium circulation passage of the cooling medium circulation device are arranged on the upper side in the vertical direction of the reducing agent injection valve, when this injection valve is arranged and fixed in place for use.
