Turntables 11 are fixedly arranged at both ends of the screw rod 7, and fixing bolts 12 are rotatably arranged on the turntable 11 through threaded connection. An array of rubber balls 13 are fixedly arranged on the clamping surface of the arc-shaped fixed plate 10; fixing holes are provided at the four corners of the fixing plate 3, and the top of the I-shaped support base 2 is provided with mounting holes that match the fixing holes provided on the fixing plate 3. Fixing screws 15 are penetrated through the above-mentioned fixing holes and the mounting holes, and fixing nuts 16 are rotatably arranged on the fixing screws 15. During operation, in order to enable the installation and fixing device to fix and install spray pipes 101 of different sizes and improve the practicability of the equipment, the staff first connects the fixing plate 3 with the fixing screws 15 through four groups of fixing screws 15. The nut 16 is fixed on the I-shaped support base 2, and then the staff rotates the turntable 11, and the turntable 11 drives the screw 7 to rotate. The rotation of the screw 7 drives the two groups of moving blocks 8 to move relative to each other, and the moving blocks 8 drive the fixing rod 9 and the arc-shaped fixing plate 10 to move.

After the arc-shaped fixing plate 10 fixes the spray pipe 101, the staff rotates the turntable 11 to fix it more firmly, and then rotates the fixing bolt 12 to limit the position of the turntable 11. Through the cooperation between the above structures, the practicality and applicability of the desulfurization spray pipe installation and fixing device are improved; when the spray pipe 101 is working, there is high temperature inside the spray tower, and the spray pipe 101 will produce smaller movement under the action of thermal expansion and contraction. When the spray pipe 101 generates stress, the spring 14 can provide deformation buffer for the spray pipe 101 to prevent the internal stress of the spray pipe 101 from causing its body to crack and be damaged, affecting its service life.
