Description
Technical Field
The utility model relates to an inside imaging technology field of high temperature furnace kiln specifically is a coke dry quenching furnace prestorage room image device.
Background
The dry quenching furnace is the main equipment of dry quenching technology, and consists of an upper furnace top cone, a pre-storage chamber (annular air passage), a chute and a cooling chamber. During the coke dry quenching process, red coke at about 1000 ℃ is loaded into a pre-storage chamber of the coke dry quenching furnace from the top of the furnace, and after the red coke is pre-stored in the pre-storage chamber for a period of time, the red coke descends to a cooling chamber along with the coke discharge, the red coke exchanges heat with inert circulating gas during the descending process in the cooling chamber, and the coke is discharged out of the coke dry quenching furnace after being cooled to about 200 ℃.
The red coke is loaded into the pre-storage chamber from the top of the dry quenching furnace, the red coke can be continuously and stably supplied to the cooling chamber, and the height, the shape and the distribution of a red coke material layer in the pre-storage chamber have important influence on the dry quenching process. When the bed of material height reaches the take the altitude, should stop to load burnt, can cause prestoring room pressure fluctuation when the bed of material height is low excessively, sometimes the material level height drops to chute, causes prestoring room pressure negative value very big to lead to a large amount of air to get into prestoring room and coke and take place violent burning when the coke is loaded, prestoring room pressure is very high again after the bell lid is gone up, has destroyed the dynamic balance of cycle gas system, keeps reasonable material level height to have an important role to balanced production simultaneously. It is therefore important to monitor the coke level in the pre-chamber at all times.
The red coke is loaded into the prestoring room, can produce different cloth shapes and particle distribution, and then lead to different cloth aliquations, and especially when the red coke charge level is lower, the red coke fall height is great, and the aliquation of cloth can increase, and the aliquation of cloth can lead to cooling air flow's segregation, causes the coke cooling degree inhomogeneous, leads to red coke heat energy can not effectively be retrieved to lead to the dry quenching cooling efficiency to reduce. Therefore, it is necessary to master the shape of the charge level and the particle distribution in the pre-storage chamber at any time after coke feeding.
In the dry quenching process, blown-in circulating gas is led out through a chute port at the lower part of the pre-storage chamber, part of the circulating gas enters the pre-storage chamber, the flow direction and the flow rate of the circulating gas at the charge level of the pre-storage chamber have important influence on the pressure of the pre-storage chamber, dust overflows to pollute the environment in the coke charging process when the pressure of the pre-storage chamber is too high, and a large amount of external air is sucked in to cause coke combustion in the coke charging process when the pressure of the pre-storage chamber is. Therefore, the flow direction and the flow rate of the circulating gas penetrating through the charge level of the pre-storage chamber have important influence on the regulation of the pressure of the pre-storage chamber, and an operator can master the gas flow condition at any time to be used as an important basis for regulating the furnace condition.
The lower part of the pre-storage chamber is provided with an annular air duct for leading out circulating gas, the annular air duct consists of an inner wall and an outer wall, and the inner wall of the annular air duct is a furnace wall of the pre-storage chamber. The annular flue is large in inner wall area, the two sides of the annular flue are a pre-storage chamber and the annular flue, wherein one side of the pre-storage chamber bears huge pressure generated when coke is static and descends, so that huge pressure difference is generated on two sides of a furnace wall, the furnace wall of the pre-storage chamber deforms and bulges or collapses, important influence is caused on production, and additionally, the pre-storage chamber furnace wall masonry material and masonry process also have important influence on furnace wall deformation. It is therefore necessary to monitor the pre-chamber oven wall shape.
At present, the internal monitoring of the pre-storage chamber of the dry quenching furnace in China only comprises material level height measurement, internal pressure measurement and internal temperature measurement. The level height measurement, in which the internal height measurement is a fixed point, does not fully reflect the level height, level shape and particle size distribution. The pressure measurement value is the real-time pressure in the pre-storage chamber, is only a pressure measurement result, and cannot reflect the reason for generating the pressure. The shape of the charge level and the furnace wall condition of the pre-storage chamber have no effective monitoring method, and the charge level and the furnace wall can only be observed manually through the furnace opening. If the production is stable and smooth, the height and the shape of the charge level in the pre-storage chamber, the shape of the furnace wall of the pre-storage chamber and the size and the distribution of the air flow in the pre-storage chamber are monitored in real time.
