Description

Technical Field

[0001] The utility model relates to the technical field of coke dry quenching production, in particular to a superheater for reducing coke powder wear in coke dry quenching production. Background Technique

[0002] A coke dry quenching furnace, also known as a coke dry quenching oven or a coke dry quenching device, is a device used to process the coke produced during the coking process. The coke dry quenching furnace is mainly used in coking plants in the iron and steel industry. Its main function is to recover heat from the red-hot coke and cool the coke to room temperature or close to room temperature for further processing and storage. Compared with traditional wet coke quenching (using water to cool the coke), the coke dry quenching furnace has higher energy efficiency and lower environmental pollution, and a superheater is required to increase the temperature inside the coke dry quenching furnace during the production process.

[0003] When the existing superheater transfers steam for a long time, since steam is converted through water flow, the transmission pipes inside the superheater are gradually filled with impurities such as water scale, which causes the impurities to gradually corrode the inside of the coke dry quenching furnace. In severe cases, blockage occurs during the transmission process, which further causes the temperature of the coke dry quenching furnace to decrease, resulting in the need to stop production of the coke dry quenching furnace to solve the blockage problem, reducing the working efficiency of the coke dry quenching furnace production and being inconvenient to use. Therefore, we have proposed a superheater for reducing coke powder wear in coke dry quenching production, which has the function of being convenient to use and is urgently needed to be developed.

A plurality of transmission pipes 334 are communicated with the outer surface of the exhaust duct 331, and one end of the transmission pipe 334 is communicated with the trapezoidal air duct 333;

[0032] Specifically, when it is necessary to clean the filter screen plate 312, the motor 314 and the fan 36 are started. The fan 36 transmits the air flow into the exhaust duct 331, and the exhaust duct 331 then transmits the air flow to the transmission duct 334. The transmission duct 334 passes the air flow through the trapezoidal duct 333, and the trapezoidal duct 333 then blows the air flow against the filter screen plate 312, so as to facilitate the falling of the impurities attached to the surface of the filter screen plate 312.

At this time, the rotating rod 316 drives the second pulley 322, the guide rod 320 and the two bevel gear parts 321 to rotate. The bevel gear part 321 drives the guide rod 320, the third pulley 324, the operating rod 323 and the cam 325 to rotate. While the cam 325 rotates, it pushes the two moving disks 326 to move away from each other. While the two moving disks 326 move, they squeeze the return spring 328, and then the moving disk 326 drives the moving rod 327 to move synchronously. The moving rod 327 drives the long plate 332 to move synchronously, so that the two long plates 332 drive the trapezoidal duct 333 to move reciprocally, so as to uniformly blow the filter screen plate 312, so as to clean the filter screen plate 312 and use it for a long time, which is convenient for improving the purity of the steam transmitted by the superheater body 2 and is convenient for use.

[0033] In summary, the working principle of a superheater for reducing coke powder wear in dry coke quenching production according to an embodiment of the present invention is as follows: when transmitting steam to the dry quenching furnace body 1, the superheater body 2 can be started to transmit it into the filtering assembly 3, and then the filtering assembly 3 intercepts impurities such as scale, so as to improve the purity of the steam during transmission. When the filtering assembly 3 is used for a long time, the filter screen plate 312 can be cleaned through the filtering assembly 3, so as to extend the use efficiency of the interception and be convenient for use.
