增加多路吹堵风的脱硫装置及脱硫方法
摘要：
一种增加多路吹堵风的脱硫装置及脱硫方法。石灰石装置布置不合理，输粉管路较长（由炉前布置的石灰石粉仓到炉后回料阀给料斜腿处），管道沿程阻力大，容易发生石灰石粉堵塞。一种增加多路吹堵风的脱硫装置，其组成包括：炉膛（1），所述的炉膛与石灰石粉仓A（2）、石灰石粉仓B（3）、床料仓（4）连接，所述的炉膛具有炉膛前墙和炉膛后墙，所述的石灰石粉仓A与电动插门板二（5）连接，所述的电动插门板二与旋转给料阀二（6）连接，所述的石灰石粉仓B与电动插门板一（7）连接，所述的电动插门板一与旋转给料阀一（8）连接，所述的床料仓与电动插门板三（9）连接，所述的电动插门板三与旋转给料阀三（10）连接。本发明应用锅炉脱硫。
摘要（英）：

The invention relates to a desulfurizer added with multiple paths of blowing and blocking air and a desulfurization method. A limestone device is unreasonable in arrangement, a powder delivery pipeline is too long (from a limestone flour cabin arranged in front of a furnace to a feeding inclined leg of a feedback valve behind the furnace), pipeline on-way resistance is great, and limestone powderblockage is easy to occur. The desulfurizer added with multiple paths of blowing and blocking air comprises a furnace hearth (1), wherein the furnace hearth is connected with a limestone powder cabinA (2), a limestone powder cabin B (3) and a bed stock bin (4); the furnace hearth has a furnace hearth front wall and a furnace hearth rear wall, the limestone powder cabin A is connected with an electric door locking sheet II (5), the electric door locking sheet II is connected with a rotary feeding valve II (6), the limestone powder cabin B is connected with an electric door locking sheet I (7),the electric door locking sheet I is connected with a rotary feeding valve I (8), the bed stock bin is connected with an electric door locking sheet III (9), and the electric door locking sheet III is connected with a rotary feeding valve III (10). The desulfurizer is used for desulfurization for a boiler.
