Description
Technical Field
The utility model relates to the field of tamping coke oven equipment, in particular to a graphite cleaning device for the root of an ascending pipe.
Background
The traditional tamping coke oven generally adopts a side coal charging mode, the fineness is often required to be controlled to be about 82-86% in order to ensure the success rate of charging coal cakes, meanwhile, as the volatile content of the matched coal is high and the coke side sometimes collapses during charging coal, the coal shortage can not be charged to cause the local oven temperature to be higher, the secondary cracking of crude gas is accelerated, the graphite rises excessively, the root part of an ascending pipe is blocked, the crude gas is not smoothly led out of a system, the coal charging smoke is generated, and the workload and the operation safety risk of cleaning the graphite at posts are increased. In addition, the large air pipe oxygen enrichment is needed to be used for erecting and sweeping the graphite at the root part for a long time, the straight lining brick is easily blown off under the high-temperature and high-pressure oxygen enrichment state, once the lining brick falls off, the external cast iron base is directly burnt to damage, the base is frequently burnt through, smoke and fire are generated, and the base needs to be frequently replaced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects that the root of the existing ascending pipe is easy to block, and the like, the utility model aims to solve the technical problems that: provides a graphite cleaning device capable of reducing the blockage of the root of an ascending pipe.
The technical scheme adopted by the utility model for solving the technical problems is as follows:
a graphite cleaning device for tedge root, including setting up annular tube and the many pipes that sweep in the tedge base on the tedge base outer lane, be equipped with an intake pipe and many outlet ducts on the annular tube, the outlet duct is linked together with the pipe that sweeps after passing the through-hole of the lateral wall of tedge base.
Furthermore, the annular pipe is fixed on the ascending pipe base after being welded with the through hole on the side wall of the ascending pipe base through the air outlet pipe.
Furthermore, the upper end of the purging pipe is fixed on the top surface of the ascending pipe base, and the side surface of the purging pipe is communicated with the air outlet pipe.
Furthermore, the purging pipes comprise four purging pipes which are arranged in a rotating array around the central axis of the ascending pipe base.
Further, the axis of the purging pipe is inclined to the periphery of the base of the ascending pipe by 0-20 degrees.
The utility model has the beneficial effects that: through increase the purge tube on current tedge base, sweep nitrogen gas through purge tube inside to the tedge root downwards, sweep away buggy and graphite that the tedge root bonded through nitrogen gas, utilize nitrogen gas cooling to reduce the root temperature simultaneously, reduce because of the secondary schizolysis of the high temperature cause crude gas, delay graphite growth speed to slow down the jam of tedge.

Marked in the figure as 1-ascending pipe base, 2-annular pipe, 3-purging pipe, 4-air inlet pipe and 5-air outlet pipe.
Detailed Description
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1 and 2, the graphite cleaning device for the root of the ascending pipe comprises an annular pipe 2 arranged on the outer ring of a base 1 of the ascending pipe and a plurality of purging pipes 3 arranged in the base 1 of the ascending pipe, wherein the annular pipe 2 is provided with an air inlet pipe 4 and a plurality of air outlet pipes 5, and the air outlet pipes 5 are communicated with the purging pipes 3 after penetrating through holes on the side wall of the base 1 of the ascending pipe. Because the environment temperature that this cleaning device is located is higher, consequently the annular tube 2, intake pipe 4, outlet duct 5 and sweep the pipe 3 and all adopt high temperature resistant tubular metal resonator to make.
The operation process of the utility model is that firstly the equipment is installed in place, then the air inlet pipe 4 is connected with an external high-pressure nitrogen tank, after the tamping coke oven works for a period of time, nitrogen is blown downwards into the root of the ascending pipe through the blowing pipe 3, the coal dust and graphite adhered to the root of the ascending pipe are blown away through the nitrogen, meanwhile, the temperature of the root is reduced by utilizing the nitrogen cooling, the secondary cracking of the crude gas caused by the higher temperature is reduced, the growth speed of the graphite is delayed, and the blockage of the ascending pipe is slowed down.
For the annular pipe 2, in order to facilitate installation, the annular pipe 2 is welded with a through hole in the side wall of the ascending pipe base 1 through the air outlet pipe 5 and then fixed on the ascending pipe base 1.
As the purge pipe 3 is subjected to a large reaction force of the purge gas, in order to improve the installation stability of the purge pipe, the upper end of the purge pipe 3 is fixed on the top surface of the ascending pipe base 1, and the side surface of the purge pipe is communicated with the gas outlet pipe 5.
The purging pipes 3 comprise four pipes and are arranged in a rotating array around the central axis of the ascending pipe base 1. According to the size of the ascending pipe, the blowing requirement can be met by only arranging four ascending pipes.
Further, the axis of the purging pipe 3 inclines for 0-20 degrees to the periphery of the riser base 1. Through the inclined purging pipe 3, the nitrogen can be effectively purged to the coal dust and the graphite on the inner wall of the ascending pipe, so that the growth speed of the graphite on the pipe wall is delayed.
According to the utility model, the purging pipe is additionally arranged on the base of the existing ascending pipe, nitrogen is purged downwards into the root of the ascending pipe through the purging pipe, coal dust and graphite adhered to the root of the ascending pipe are purged through the nitrogen, meanwhile, the temperature of the root is reduced by using nitrogen cooling, secondary cracking of raw coke oven gas caused by high temperature is reduced, and the growth speed of the graphite is delayed, so that the blockage of the ascending pipe is reduced, and the ascending pipe has good practicability and application prospect.
