Embodiment Construction

[0014] A clean heat recovery coke oven vault redirection quantitative adjustment air distribution sleeve, which includes a sleeve 1, a redirection device 2, a sealing device 3, an adjustment device 4, an indicating device 5 and a limit device 6, the sleeve 1 There is an upper device 2 installed on it, and an adjusting device 4 , an indicating device 5 , and a limit device 6 are arranged on the redirecting device 2 , and a sealing device 3 is arranged between the casing 1 and the redirecting device 2 . The size of the sleeve 1 is equivalent to the size of the originally designed air distribution port on the top of the furnace, and it is directly inserted from the top air distribution port. The air distribution adjustment is controlled by the adjustment device 4, the indicator device 5, and the limit device 6. The operation is simple and the instructions are clear. It is easy to replace; the air distribution redirection function is realized by the bushing 1 and the redirectio...

Abstract

The invention relates to a direction-changing quantitatively-adjustable air distribution sleeve at the vault of a clean heat recovery coke oven. The air distribution sleeve comprises a sleeve, a direction-changing device, a sealing device, an adjusting device, an indicating device and a stop device, wherein the sleeve is provided with the direction-changing device, the direction-changing device is provided with the adjusting device, the indicating device and the stop device, and the sealing device is arranged between the sleeve and the direction-changing device. According to the invention, through additional arrangement of the air distribution sleeve, one air distribution at the vault enters into a coking chamber after changing of direction, so a vertical fire pillar is prevented from being perpendicular to the surface of a coke cake and air distribution amount can be quantitatively adjusted; thus, burning loss of coke is effectively controlled, coal consumption is substantially reduced, economic benefits of the heat recovery coke oven are greatly improved, and competitiveness of the heat recovery coke oven is enhanced.

Description

[0001] technical field [0002] The invention belongs to a coke oven air distribution sleeve, in particular to a clean heat recovery coke oven vault redirection quantitative adjustment air distribution sleeve. Background technique [0003] The QRD-2000 clean heat recovery tamping coke oven independently developed by Shanxi Chemical Industry Design Institute is a negative pressure operation. The original design of the vault is equipped with 5 air distribution ports. Five air outlets enter the carbonization chamber and are perpendicular to the surface of the coke cake, forming five pillars of fire, causing serious coke formation on the surface of the coke cake at this position, and obvious coke pits appear. According to experience, the adjustability is poor, which not only brings economic losses to the enterprise, but also causes energy waste. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the above-mentioned de...
