Description
The technical field is as follows:
the utility model relates to a be applicable to steam soot blower rifle body advance and retreat auxiliary device of thermal power station.
Background art:
the steam soot blower of the thermal power plant utilizes steam flow with certain temperature and pressure to increase enthalpy drop, improve outlet flow rate, generate larger impact force and sweep soot on a heating surface through a convergent-divergent nozzle with continuously-changed section. The method is mainly used for removing the deposited ash and the slag on four tubes of a superheater, a water-cooled wall, an economizer and the like. It can also be used for removing the deposited ash and slag in the furnace top and the air preheater. The frequency of soot blower usage is determined by the boiler operating conditions and the quality of the coal being burned. The boiler has good operation condition, no pressure difference change, good combustion coal quality, no occupation of an attached pipe wall, and extremely low use frequency of the soot blower when no coking occurs, and on the contrary, the frequency is improved by the soot blower. Regardless of the use frequency of the soot blower, when the soot blower operates, due to the reasons of machinery, electrical appliances and the like, the soot blower is often clamped in a furnace, so that the mechanical clamping is caused, the soot blower cannot extend into the furnace and retreat from the furnace, the failure rate is high, the service life is short, the energy consumption is high, and the tube explosion accident is easily caused. In such a case, daily inspection of the soot blower reinforcement device and daily maintenance of the spare soot blower are required. However, in the process of maintenance of the steam soot blower, due to the particularity of the structure of the device, the normal overhaul and maintenance are greatly difficult. The maintenance efficiency of the soot blower is reduced directly, and the effective maintenance of the soot blower cannot be completed in a limited time. Greatly reducing the efficiency of soot blower maintenance. Hidden troubles are buried in the safe and stable operation of the boiler.
In the maintenance of the soot blower, due to the particularity of the structure of the device, when the soot blower cannot advance and retreat the gun body normally automatically, the soot blower needs to advance and retreat manually. When the manual advancing and retreating device is used, the manual advancing and retreating period of the IR type soot blower is about 15 minutes, and the manual period of the IK type soot blower is about 60 minutes. Especially when the unsmooth condition takes place in soot blower operation in-process, general manual rifle mode of withdrawing very easily causes the rifle body can't in time withdraw from, causes the soot blower rifle head to burn out, and the water-cooled wall or over heater, reheater pipeline blow loss, blows even and explodes the condition and takes place, buries down great hidden danger for boiler safety and stability operation.
The utility model has the following contents:
the utility model aims at providing a be applicable to steam soot blower rifle body advance and retreat auxiliary device in thermal power station.
