Embodiment 1

[0047] like Figure 1-2 The shown coke oven carbon reduction and anti-coke system includes a coking and carbonizing chamber 2 and a combustion chamber 5 arranged in the coke oven 1. The top of the coking and carbonizing chamber 2 is provided with an air intake pipe 4, and the top of the coking and carbonizing chamber 2 is provided with The coal feeding manhole 2-1, the air inlet pipe 4 runs through the carbonization chamber 2 of the coke oven 1, and the air inlet pipe 4 is hoisted on the top of the carbonization chamber 2 through the bracket 3 (the bracket 3 can be preferentially installed at the top of the carbonization chamber 2 when the existing coke oven 1 is improved. Near the riser pipe, if the new equipment is installed, the location can be selected according to needs), the air intake pipe 4 is provided with a number of air holes, the bottom of the combustion chamber 5 is provided with a regenerator 6, the regenerator 6 is connected to the flue chimney 8, and the flue is...

Embodiment 2

[0049] like Figure 3-4 As shown, in this embodiment, on the basis of Embodiment 1, a catalyst mesh 10 is arranged on the top of the intake pipe 4, and the catalyst mesh 10 is installed on the top of the carbonization chamber 2 through a grid-structured catalyst support 3, and the catalyst accelerates and promotes the carbonization chamber. 2 Reversible reaction at the top, and the action of the catalyst makes the chemical reaction to the desired goal occur.

Embodiment 3

[0051] like Figure 5-6 As shown, in this embodiment, on the basis of Embodiment 1, the outer periphery of the intake pipe 4 is covered with a catalyst mesh 10, which can be installed in a sleeved manner. The principle is the same as that of Embodiment 2.

Abstract

The invention discloses a coke oven carbon reduction and coke prevention method and system in the technical field of coke ovens, and the method comprises the following steps: introducing coke oven flue gas into the top of a coking carbonization chamber, and controlling the temperature of the top of the coking carbonization chamber at 850-1450 DEG C; the system comprises an air inlet pipe extending into the top of the coke oven, an air inlet pipe section extending into the coke oven is installed in the coke oven through a support, and a plurality of air holes are formed in the air inlet pipe section extending into the coke oven; the method solves the problem that graphite in the existing coke oven top ascending pipe is difficult to remove.

Description

technical field [0001] The invention relates to the technical field of coke ovens, in particular to a method for preventing coke ovens. Background technique [0002] A certain amount of high-temperature waste gas is generated in the coke oven production process. The temperature of the coke oven top reaches about 950 °C. The waste gas generated in the coke oven coking process will crack some macromolecular hydrocarbons into methane under the action of high temperature, and the methane continues to Under the action of high temperature, free carbon and hydrogen are cracked. Free carbon is easily attached to the coke oven roof of the exhaust gas, and then forms a graphite layer that adheres very strongly to the bricks. If the graphite layer is not removed in time, the growth of graphite will be accelerated due to the smaller channel of the riser. Eventually, the high-temperature coke oven interrupted production, causing the company to suffer huge economic losses. According to...
