Coke oven flue suction adjusting device and its application method

Abstract

The invention relates to the field of coke ovens for dry distillation production of coal gas, coke, tar, or analogues, in particular to a coke oven flue suction adjustment device and a use method thereof. The coke oven flue suction adjustment device comprises a damper plate (1), the device is characterized in that: it also includes side fixed mounts (21), a middle fixed mount (22), a support (23), fixed pins (3) and a lifting apparatus (4), both sides of the damper plate (1) are respectively attached to a side fixed mount (21), the middle part of the damper plate (1) is attached to the middle fixed mount (22), the damper plate (1) and the side fixed mounts (21), and the damper plate (1) and the middle fixed mount (22) are all fixed by the fixed pins (3). The use method of the coke oven flue suction adjustment device is characterized by being carried out according to the step of: adjusting the height of the damper plate (1) to realize adjustment of flue suction. The coke oven flue suction adjustment device is convenient to adjust, can avoid influence production, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of coke ovens used for dry distillation to produce gas, coke, tar or the like, in particular to a coke oven flue suction adjusting device and a method for using the same. Background technique [0002] With the development of coking production, the requirements for the adjustment quality of coke oven process parameters are higher. The stability of the suction of the coke oven flue plays an important role in maintaining the uniform heating of the coke oven, effectively controlling the tightness of the coke oven masonry, improving the quality of coke and prolonging the life of the coke oven. The coke oven flue regulating device is a device to adjust and control the flue suction in the coke oven heating system. The magnitude of the flue suction will directly affect the rate of rising and falling airflow in the heating system, and it is the main force of gas flow in the coke oven heating system. . In order to meet the ai...

Problems solved by technology

However, in actual work, because the flaps are in a high-temperature and high-corrosion environment all the year round, the flue flaps are seriously hung, and the adjustment of the flue flaps often occurs. In severe cases, the shafts of the flaps are broken, and the flaps fail and die. It cannot be adjusted; when replacing the flap of the flue, it not only requires a lot of manpower and material resources, but also stops heating the heating system, stops the coke output of the coke oven, and removes the lining bricks inside the flue, which is extremely unfavorable for the service life of the coke oven and safety production
