Title:
REACTION DEVICE OF SCR SYSTEM FOR SHIPS
Document Type and Number:
WIPO Patent Application WO/2021/147859
Kind Code:
A1
Abstract:
A reaction device of an SCR system for ships. The reaction device comprises a conveying unit (110), a reaction chamber (120), at least one catalyst module (130), and an air equalizing chamber (140). The conveying unit (110) comprises an input pipeline (111) and an output pipeline (112), and the output pipeline (112) is fitted over the input pipeline (111); one end of the reaction chamber (120) is connected to the conveying unit (110), the reaction chamber (120) comprises an inner cylinder (121) and an outer cylinder (122), the outer cylinder (122) is fitted over the inner cylinder (121), the inner cylinder (121) is communicated with the input pipeline (111), and the outer cylinder (122) is communicated with the output pipeline (112); the catalyst module (130) is provided between the inner cylinder (121) and the outer cylinder (122); the air equalizing chamber (140) is connected to the other end of the reaction chamber (120) and is communicated with the inner cylinder (121) and the outer cylinder (122). According to the reaction device of the SCR system for the ships, the outer cylinder is fitted over the inner cylinder, and smoke flows from the inner cylinder back into the outer cylinder after being turned by the air equalizing chamber, so that the size of the reaction device can be greatly reduced so as to improve the integration of the SCR system, and the smoke turns in the air equalizing chamber and then flows back, so that the smoke and a reducing agent can be fully mixed in the air equalizing chamber, so as to improve the catalytic reaction efficiency.
