Description

Coke oven brick gas duct mud jacking sealing tube

Technical Field

The utility model relates to a mud jacking sealing tube for coke oven brick gas duct.

Background

The coke oven is a large industrial kiln built by refractory bricks, and is a reheating coke oven with multiple duplex flame paths, waste gas circulation, coke oven gas downward injection and blast furnace gas side injection. In the production process of the coke oven, the coke oven is influenced by various factors such as coking time change, system maintenance, equipment failure and the like, along with the increase of the oven age of the coke oven, the oven masonry is naturally aged and damaged, and the hot repair maintenance is a problem to be faced by each coke oven. The coke oven brick gas channel is used as a channel for coke oven gas to enter the combustion chamber, the blowby of the brick gas channel not only enables the entering gas to be combusted in the heat accumulation chamber or the small flue, wastes gas resources, reduces the gas quantity entering the oven, causes abnormal oven temperature, but also causes detonation in the exchange process, damages pipe bricks, reduces the sealing performance of the oven body along with the increase of the oven age, and a large amount of blowby of the brick gas channel can seriously affect the heating of the coke oven, particularly the blowby of the oven end brick gas channel can affect the normal regulation of the thermal engineering of the coke oven, the quality of coke and the service life of the oven body.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a coke oven brick gas duct mud jacking sealing tube aiming at the problems in the prior art.

The utility model discloses a concrete technical scheme as follows:

the mud jacking sealing pipe for the coke oven brick gas pipeline comprises a spray pipe and a conveying pipe connected with the spray pipe, wherein the end of the spray pipe is closed, and spray nozzles are uniformly distributed on the pipe wall of the spray pipe;

furthermore, the nozzles are uniformly distributed around the pipe wall of the spray pipe in four rows, and the number of the nozzles in each row is not less than three;

further, the conveying pipe is connected with the spray pipe through a threaded pipe hoop;

further, the conveying pipe is connected by a plurality of pipe sections, and adjacent pipe sections are connected by a threaded pipe hoop.

The utility model discloses following beneficial effect has:

this use novel can block up the blowby position at brick gas channel fast to can adjust according to the position at blowby position the utility model discloses a length, operation process are swift convenient, and the shutoff is effectual.

Detailed Description

The mud jacking sealing pipe for the coke oven brick gas channel shown in figure 1 comprises a spray pipe 1 and a conveying pipe 2 connected with the spray pipe 1, wherein the end of the spray pipe 1 is closed, and spray nozzles 3 are uniformly distributed on the pipe wall of the spray pipe 1; the nozzles 3 are uniformly distributed around the pipe wall of the spray pipe 1 in four rows, and the number of the nozzles 3 in each row is not less than three; the conveying pipe 2 is connected with the spray pipe 1 through a screw thread pipe hoop 4; the delivery tube 2 is connected by a plurality of tube sections, adjacent tube sections being connected by a threaded ferrule 4.

The utility model discloses a concrete working process as follows:

determining the blowby position of the brick gas channel, and setting the length of the conveying pipe 2 according to the position of the blowby position: connecting the multiple sections of pipe sections through screw thread pipe hoops 4 until the spray pipe 1 can reach the blowby position of the brick gas channel; the spray pipe 1 is stretched into the blowby position of the brick gas channel, the plugging slurry is conveyed to the spray pipe 1 through the conveying pipe 2 and is sprayed out through the nozzle 3, and the blowby position of the brick gas channel is rapidly plugged.
