Description

Technical Field

[0001] The utility model relates to the technical field of riser pipes, in particular to dust removal equipment for riser pipes on a coking plant furnace top. Background Art

[0002] The riser is installed at the riser port on the top of the coke oven. It is an auxiliary equipment of the coke oven used to discharge the raw gas in the carbonization chamber. The main function of the riser is to discharge the raw gas. The tar vapor in the raw gas is cooled or condensed when it encounters a cold heat exchange interface. The lower the raw gas cooling temperature, the greater the amount of tar precipitation.

[0003] However, some riser pipes now do not have a cleaning function, and tar is easily attached to the inner wall of the riser. If it is not cleaned for a long time, dust will also adhere to the tar, which will affect the use of the riser in the long run. For this reason, we propose a coking plant furnace top riser dust removal equipment to solve the above problem. Utility Model Content

[0004] The purpose of the utility model is to provide a coking plant furnace top riser dust removal device to solve the problems raised in the above background technology.

[0006] Further preferably, an electric push rod is fixedly connected to the inner wall of the riser tube body, and the movable end of the electric push rod is fixedly connected to a rectangular box.

[0007] Further preferably, a high-pressure nozzle is connected to the bottom of the rectangular box.

[0008] Further preferably, the left side of the riser pipe body is fixedly connected to a water tank, and the top of the water tank is fixedly connected to a water pump.

[0009] Further preferably, the water inlet of the water pump extends into the water tank, and the water outlet of the water pump is connected to a water outlet pipe.

[0010] Further preferably, a connector is embedded on the left side wall of the riser pipe body, the water outlet pipe is connected to a hose through the connector, and the other end of the hose is connected to the rectangular box.

[0011] Further preferably, a water filling port is provided on the top of the water tank.

[0012] The tar then flows through the concave portion at the bottom of the filter screen and onto the inner wall of the riser tube body, and then flows downward, and finally converges at the annular notch portion under the action of gravity. The right side of the annular notch portion is higher than the left side, so that the tar flows to the left and is discharged through the discharge pipe. When the filter screen needs to be cleaned, the electric push rod is started, and the movable end of the electric push rod drives the rectangular box to move to the right to the top center of the filter screen, and the water pump is started. The water pump draws out the cleaning liquid in the water tank and transports it to the rectangular box through the outlet pipe and the hose, and finally flushes and cleans the filter screen through the high-pressure nozzle. Similarly, the water flow can also be discharged through the discharge pipe, thereby preventing the tar from adhering to the filter screen and the inner wall of the riser tube body, and can automatically clean the tar and dust, saving time and effort.
