Embodiment Construction
[0019] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0020] see Figure 1 ~ Figure 3 , the temperature of the roof space 5 of the 7.63-meter coke oven is relatively high, because the 7.63-meter coke oven has both the upper spanning hole 3 and the lower spanning hole 4, and the roof space 5 of the 7.63-meter coke oven is caused by the upper spanning hole 3 The temperature is on the high side.
[0021] A method for transforming a 7.63-meter coke oven of the present invention is to put the gunning material into the hopper of the gunning machine 1; the spray gun 2 of the gunning machine 1 enters the 7.63-meter coke oven through the fire viewing hole 6 of the 7.63-meter coke oven Spray the gunning material layer by layer until the upper spanning hole 3 of the 7.63-meter coke oven is closed, and ensure that the fire viewing hole of the 7.63-meter coke oven is unblocked. Only the lower spanni...

Abstract
The invention relates to a reconstruction of a 7.63 meter coke oven. The invention discloses a method for reconstructing the 7.63 meter coke oven, which comprises the following steps: 1) a gunning material is filled into a hopper of a gunning machine; 2) a spray gun of the gunning machine is penetrated into a cross-over hole on an upper part of the 7.63 meter coke oven through a peephole of the 7.63 meter coke oven; 3) the gunning material is sprayed to the cross-over hole on the upper part layer by layer through a spray machine, until the cross-over hole on the upper part of the 7.63 meter coke oven is sealed, and the peephole of the 7.63 meter coke oven is guaranteed unblocking. According to the invention, the furnace roof space temperature of the 7.63 meter coke oven is reduced, and the reconstruction method is capable of solving the problem of abnormal production of the 7.63 meter coke oven and chemical product workshop, improving the production operation state of the 7.63 meter coke oven, raising the economic benefit of the coke plants and prolonging the service life of the 7.63 meter coke oven.
Description
technical field [0001] The invention relates to a transformation of a 7.63-meter coke oven, in particular to a transformation method of a 7.63-meter coke oven. Background technique [0002] At present, the temperature of the top space of the German 7.63m coke oven introduced in China is relatively high. The main reasons for this problem are two aspects. The rice coke oven adopts the technology of "differential heating". Due to these two reasons or the combination of the two reasons, the temperature of the roof space of the 7.63m coke oven is relatively high. The consequences caused by the high temperature in the top space are as follows: 1. The graphite accumulation in the top space is serious, which makes it difficult to level coal and push coke; 2. The interior of the coke oven riser has a lot of graphite, and sometimes even blocks the riser, which seriously affects the coke oven. Normal production caused serious leakage of raw gas at the top of the coke oven during oper...
