EXHAUST GAS AFTERTREATMENT UNIT AND CONSTRUCTION VEHICLE EQUIPPED WITH SAME
선택 촉매 환원 장치(22), 분사 장치(24), 냉각수 공급 배관(25), 및 냉각수 복귀 배관(26)을 구비한다. 분사 장치(24)는, 선택 촉매 환원 장치(22)에 공급되는 배기 가스 중에 환원제를 분사한다. 냉각수 공급 배관(25)은, 냉각수를 분사 장치(24)에 공급한다. 냉각수 복귀 배관(26)은, 분사 장치(24)로부터 냉각수를 배출한다. 냉각수 공급 배관(25) 및 냉각수 복귀 배관(26)은, 분사 장치(24)와 접속 하여 분사 장치(24)로부터 위쪽으로 연장되는 대류부(25c, 26c)를 포함한다.
An exhaust treatment unit for a work vehicle includes a selective catalytic reduction apparatus, a connection pipe, an ejection apparatus attached to the connection pipe, a first pipe section that guides coolant to the ejection apparatus, a second pipe section that discharges coolant from the ejection apparatus, first and second retaining sections, and a coolant pump. The ejection apparatus ejects reducing agent into exhaust supplied to the selective catalytic reduction apparatus. The first and second retaining sections retain coolant and are connected to the first and second pipe sections above the ejection apparatus, respectively. The coolant pump is driven by an engine driving force and supplies the coolant to the ejection apparatus via the first pipe section. The first and second pipe sections extend upward from first and second connecting sections of the first and second pipe sections and the ejection apparatus toward the first and second retaining sections, respectively.
