Description

TECHNICAL FIELD

[0001] The utility model relates to the design technical field of soot blower, especially to a soot blower for cement plant. BACKGROUND

[0002] At present, the flue gas of cement plant production needs to be treated by denitration system to reach the standard before being discharged. In order to ensure the effective atomization of ammonia water spray gun nozzle and the non-caking dust accumulation around the nozzle, most projects set soot blower for its dust removal. Because the flue gas through the ammonia water spray gun has the conditions of high dust concentration, large viscosity and complex composition, the soot blower should have good adaptability to this working condition. However, although the soot blower can effectively remove the dust of ammonia water spray gun nozzle, improve the atomization effect and prolong the service life, the working condition has many factors affecting the soot blower, such as high dust concentration which easily leads to poor dust removal effect of the soot blower; improper selection of the form and size of the nozzle on the soot blowing rake pipe will lead to the phenomenon of blowing damage of the spray gun pipeline and nozzle, and even affect the standard discharge of flue gas, and because the existing soot blower cannot approach the edge of the spray gun nozzle during work, the edge area has the problem of poor dust removal effect, in addition, after the work is completed, the outer wall position of the soot blowing target pipe is also covered with a large amount of dust, and long-term accumulation will also cause the problem of short service life of the soot blowing target pipe.

[0003] The dust blowing device for a cement plant disclosed in the authorized announcement No. CN218721585U can make the dust blowing target pipe closer to the edge of the lance nozzle through the connection of the elbow pipe on the upper end of the dust blowing target pipe, so as to realize the dust blowing effect on the edge of the lance nozzle. The dust blowing device for a cement plant has the advantage that the dust blowing target pipe is closer to the edge of the lance nozzle, avoids the problem that the edge cannot be close to the lance nozzle, and improves the practicability of the device. Although the device has the advantage that the dust blowing target pipe is closer to the edge of the lance nozzle, avoids the problem that the edge cannot be close to the lance nozzle, and improves the practicability of the device, only the edge close to the lance nozzle is considered, and the position of the outer wall of the dust blowing target pipe after long-time work is also covered with a large amount of dust. The device is provided with a control box. The third gear drives the fixed rod to rotate clockwise, the fixed rod drives the fourth gear to rotate clockwise, the fourth gear and the gear belt are engaged, the gear is driven to advance, the air cylinder enters the denitration system, and the device is carefully blown away from the denitration system. Thus, the T-shaped fixed block collides with the reverse button during the advancing process, the motor rotates counterclockwise, the device driven by the motor rotates counterclockwise, the air cylinder is discharged from the denitration system, the problem that the air cylinder is damaged due to long-time accumulation of dust is prevented, and the service life of the air cylinder is prolonged. During the retreating process, the T-shaped fixed block collides with the reverse button, the motor resumes clockwise rotation, and the device is carefully blown away. Thus, the flexibility of the device is improved, and the service life of the device is also increased. Practical new type content
