Description

Flow guider for preventing coke oven brick gas channel from leaking

Technical Field

The utility model belongs to the technical field of coke oven heating, and particularly relates to a fluid director for preventing a coke oven brick gas channel from leaking.

Background

The utility model is specially designed for the blowby of the brick gas channel of the coke oven, and can solve the problem that the blowby condition often appears in the brick gas channel of the coke oven and seriously affects the sealing performance of the oven body because the oven temperature frequently fluctuates and the regenerative chamber part of the coke oven generates uneven expansion because of frequent change of the turnover time of the coke oven in the normal heating of the coke oven.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a flow guider for preventing a coke oven brick gas channel from leaking so as to solve the problems.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the flow guider for preventing the leakage of the coke oven brick gas channel comprises a vertical pipe, wherein a lower flow guide pipe penetrates through the vertical pipe, a reducing pipe is sleeved at the upper end of the lower flow guide pipe, the outer diameter of the large end of the reducing pipe is matched with the inner diameter of the vertical pipe, an upper flow guide pipe is arranged at the top end of the lower flow guide pipe, and a gas inlet is formed in the outer wall of the bottom of the lower flow guide pipe.

In order to further realize the utility model, the lower guide pipe and the upper guide pipe are in threaded connection.

In order to further realize the utility model, the reducing pipe is a concentric reducing pipe, the upper end is a big end, and the lower end is a small end.

In order to further realize the utility model, the length of the upper flow guide pipe is 1500mm, 2500mm or 3000 mm.

In order to further realize the utility model, the diameters of the upper guide pipe and the lower guide pipe are both 32 mm.

In order to further realize the utility model, the diameter of the large end of the reducing pipe is 38mm, and the diameter of the small end of the reducing pipe is 34 mm.

To further realize the utility model, the diameter of the stand pipe is 45mm, and the length is 600 mm.

In order to further realize the utility model, the coal gas inlet is arched, and the bottom opening is flush with the lower end opening of the lower flow guide pipe.

Compared with the prior art, the utility model has the beneficial effects that:

the utility model is arranged on the brick gas channel, the flow guide pipe is connected with the threads in the vertical pipe of the basement to form interference fit, and the flow guide device is prevented from sinking. The upper guide pipe with different lengths is manufactured according to different coal gas leakage points, and the lower guide pipe is in threaded connection with the upper guide pipe and then conducts drainage, so that the purpose of solving the coal gas leakage can be achieved.
