一种用于SCR脱硝系统前的高温预除尘装置
摘要：
本实用新型提供的一种用于SCR脱硝系统前的高温预除尘装置，包括壳体(1)、设于壳体(1)底部的集灰斗(2)和固定于壳体(1)上的可翻转预除尘单元(3)，所述可翻转预除尘单元(3)底部设于集灰斗(2)的顶部边缘。该除尘装置结构简单、使用方便，可将SCR入口对催化剂造成巨大磨损的大颗粒除去，从而降低催化剂的磨损，延长催化剂在燃用高灰份煤机组上的使用寿命；通过控制金属烧结滤片的孔隙尺寸，控制预除尘颗粒的范围，具有预除尘效果好、阻力小、结构简单、适用面广等优点。
摘要（英）：

The utility model provides a high temperature pre-dedusting device before an SCR (selective catalytic reduction) denitration system. The high temperature pre-dedusting device includes a casing (1), a dust collecting bucket (2) arranged at the bottom of the casing (1), and an overturning pre-dedusting unit (3) fixed on the casing (1), wherein the bottom of the overturning pre-dedusting unit (3) is arranged on the top edge of the dust collecting bucket (2). The dedusting device is simple in structure and convenient to use, can remove large particles seriously abrading a catalyst at an SCR inlet, thereby reducing abrasion of the catalyst and prolonging the service life of the catalyst on a coal fired high ash content coal unit; a hole size of a metal sintering filter disc is controlled, so as to control the size range of pre-dedusting particles, and the high temperature pre-dedusting device has the advantages of good pre-dedusting effect, small resistance, simple structure, wide application range, and the like.
