Abstract
Description
Technical Field
[0001] The invention relates to the technical field of dry quenching of coke in the coking industry, and in particular to a ramp maintenance support device and a use method thereof. Background Art
[0002] The so-called dry quenching, relative to wet quenching, refers to a method of quenching red coke by using inert gas to cool it down. During the dry quenching process, red coke is loaded from the top of the dry quenching furnace, and the low-temperature inert gas is blown into the red coke layer in the cooling section of the dry quenching furnace by the circulating fan to absorb the sensible heat of the red coke. The cooled coke is discharged from the bottom of the dry quenching furnace, and the high-temperature inert gas coming out of the annular flue of the dry quenching furnace flows through the dry quenching boiler for heat exchange. The boiler generates steam, and the cooled inert gas is blown back into the dry quenching furnace by the circulating fan. The inert gas is circulated in a closed system.
[0003] The dry quenching furnace is the main equipment of the dry quenching coke unit. Dry quenching coke operation units with different processing capacities select dry quenching furnaces of different specifications. The main functions of the dry quenching furnace include the following two aspects: First, as a storage device for red coke, it can pre-store some red coke. Second, as a device for quenching red coke, the coke temperature is reduced to below 200℃ through the blast device installed at the bottom of the dry quenching furnace.
[0004] The dry quenching furnace is mainly used for dry quenching coke pre-storage and cooling of coke. The dry quenching furnace consists of a pre-storage section, a chute area and a cooling section. The dry quenching furnace is a vertical trough with a circular cross-section. The outer shell is made of steel plates and steel sections, and the inner lining is heat-insulating and wear-resistant materials. An annular water seal groove is set on the top of the dry quenching furnace. The upper part of the dry quenching furnace is the pre-storage section, the middle is the chute area, and the lower part is the cooling section. The pre-storage section is used to receive intermittently loaded red coke, and has a buffering function to compensate for production fluctuations; the chute area is an important part of the dry quenching furnace. Its main function is to absorb the sensible heat of the red coke from the low-temperature circulating gas entering from the gas supply device at the bottom of the dry quenching furnace, and then discharge it through the chute and annular gas duct, and flow through the dry quenching boiler for heat exchange. The wall made of refractory materials in the middle of every two chute openings is usually called a "bull leg". The cooling section is located at the bottom of the dry quenching furnace. Its function is to make the red coke exchange heat with the low-temperature circulating gas, and discharge it after cooling, so as to achieve the purpose of cooling the coke;
[0005] Due to the special characteristics of the CDQ system with continuous production and operation, the red-hot CDQ coke is continuously loaded into the CDQ furnace from the top, and is discharged from the CDQ furnace through the pre-storage chamber, cooling chamber, and coke discharge device. Therefore, the CDQ furnace is in a high temperature state for a long time. The internal refractory materials of the CDQ furnace are corroded and worn by high-temperature coke, flue gas, and coke powder for a long time, resulting in different degrees of damage to the refractory materials of the CDQ furnace, which seriously affects the normal production of CDQ. Therefore, it is necessary to stop the CDQ every year, and repair the internal refractory materials after the CDQ furnace is cooled down. The most severely damaged part of the internal refractory materials of the CDQ furnace is the bull leg part of the ramp area, which will be rebuilt, repaired and inspected every year during the annual maintenance.
[0006] This patent is to manufacture a CDQ dry quenching furnace inclined channel corbel maintenance support device, which supports and protects the top of the inclined channel openings at both ends of the corbel, ensures the safety of operations such as removing and replacing the corbel, and avoids the potential safety hazard of partial collapse of the inclined channel corbel due to factors such as large vibration and large removal area during the process of masonry or removal and replacement of the corbel. After on-site maintenance, the effect is very good, which brings convenience to the inspection and maintenance of the CDQ dry quenching furnace inclined channel corbel. Summary of the invention
