Description

TECHNICAL FIELD

[0001] The utility model relates to a slag pipe equipment technical field, concretely relates to a slag pipe inclined pipe automatic ramming device. BACKGROUND

[0002] The development and application of circulating fluidized bed boiler technology have been widely applied. The technology is one of the advanced technologies for clean coal combustion and realizing sustainable development strategy. It integrates the advantages of energy saving, clean combustion, safety and reliability, and pollution emission reduction. However, in the actual operation of the boiler, some local structural problems will also affect the efficiency of the boiler, such as the frequent blockage problem of the boiler slag pipe, which seriously affects the safe and economic operation of the boiler.

[0003] Among them, at the position where the pipe of the slag pipe is connected to the circulating fluidized bed boiler, there is a segment of inclined pipe, which converts the slag pipe from a horizontal pipe to a vertical pipe. Due to the turning position at this location, it is in a high blockage area. If it cannot be handled well, once the slag pipe is blocked, it can only be dredged after the boiler is stopped. On the other hand, frequent blockage may also cause the bed pressure of the boiler furnace to rise, causing potential damage to the boiler and downstream equipment of the slag pipe, and increasing the cost and frequency of equipment maintenance.

[0004] At present, the dredging method of the circulating fluidized bed boiler slag pipe is to install a ramming pipe on the top of the slag pipe to facilitate manual dredging when the slag is blocked. Once the slag pipe is blocked, the conventional dredging method is to organize personnel to insert a ramming rod into the boiler slag pipe for manual ramming. The labor intensity of the on-site operator is high. Because the circulating fluidized bed boiler furnace is under slight positive pressure, there is a risk of high-temperature ash leakage during ramming, which is easy to cause burns and has a major safety hazard.

The surface of the slag poking rod 2 is blown at high speed in the blowing gap 29. On the one hand, the surface of the slag poking rod 2 can be cooled by blowing. On the other hand, the floating dust remaining on the surface of the slag poking rod 2 can be removed, and the smoothness of the slag poking rod 2 in the reciprocating movement of the dredging pipe opening 36 can be improved. The air and floating dust after blowing are discharged through the movable hole 31. After the slag poking rod 2 moves upward, the movable plate 24 is attached to the dredging pipe opening 36, and then the elastic tube 25 is compressed. When the slag poking rod 2 moves downward, the elastic tube 25 is restored. By means of the elastic tube 25, a blowing cavity can be formed on the surface of the slag poking rod 2, the surface of the slag poking rod 2 can be blown at high speed, and the air after blowing can only be discharged along the movable hole 31, so that a high-speed airflow can be formed on the surface of the slag poking rod 2.
