一种脱硝系统中热解炉的冲洗管路
摘要：
本发明提供了一种脱硝系统中热解炉的冲洗管路，属于机械技术领域。它解决了现有的脱硝系统尿素溶液冲洗效果差的问题。本脱硝系统中热解炉的冲洗管路包括冷水管、热水支管一以及用于冲洗尿素溶液的冲洗管，冷水管的出口及热水支管一的出口均与冲洗管相连通，该冲洗管路还包括由脱硝系统所在的锅炉机组引出的凝结水管，冷水管的入口与热水支管一的入口均与凝结水管相连通，热水支管一沿由脱硝系统所在锅炉机组上的烟道外侧布置，冲洗管上设有温度表，且该冲洗管路还包括能够对热水流量进行调节的热水调节阀以及能够对冷水流量进行调节的冷水调节阀。它具有冲洗效果好、减少锅炉机组热量损失等优点。
摘要（英）：

The invention provides a flushing pipeline of a pyrolyzing furnace in a denitrification system, and belongs to the technical field of machineries. The problem of poor flushing effect of a urea solution in an existing denitrification system is solved. The flushing pipeline of the pyrolyzing furnace in the denitrification system comprises a cold water pipe, a hot water branch pipe I, a flushing pipe, a condensate pipe, a hot water regulating valve and a cold water regulating valve. The flushing pipe is used for flushing a urea solution, and an outlet of the cold water pipe and an outlet of the hot water branch pipe I both communicate with the flushing pipe. The condensate pipe is drawn from a boiler unit where the denitrification system is located, an inlet of the cold water pipe and an inlet of the hot water branch pipe I both communicate with the condensate pipe, the hot water branch pipe I is arranged along the outer side of a flue on the boiler unit where the denitrification system is located, and a temperature meter is arranged on the flushing pipe. The hot water regulating valve can regulate hot water flow and the cold water regulating valve can regulate cold water flow. The flushing pipeline of the pyrolyzing furnace in the denitrification system has the advantages that the flushing effect is good and heat loss of the boiler unit is reduced.
