Problems solved by technology

"However, this technical solution cannot control the pressure of the injected brick gas channel. When the pressure is high, the mud may still be sprayed into the combustion chamber. When the pressure is low, some cracks cannot be sealed; in addition, the mud is always in the In the flowing state, there is not enough penetration time for transverse cracks, so it is only suitable for repairing the surface of brick gas channels, and it is easy to fall off after drying

Embodiment Construction

[0021] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0022] like figure 1 Shown, a kind of method for grouting and sealing of brick gas channel of the present invention comprises the following steps:

[0023] 1) Confirmation of the sealing range and calculation of the sealing parameters; firstly, confirm the part that needs to be sealed in the coke oven brick gas channel 1, and then determine the required height of the mud 2 in the brick gas channel 1, and calculate the required height when reaching the height. The volume of the mud 2 that needs to be pressed in; the mud 2 is pressed in quantitatively by the gear pump, and the working time of the gear pump is calculated according to the volume of the mud 2 required and the output flow of the gear pump;

[0024] 2) Preparation before sealing operation; prepare the mud 2 used for sealing the brick gas channel, the specific gravity of the mud 2 is 1.6...

Abstract

The invention relates to a brick gas passage mud jacking and sealing method, comprising: 1) determining a sealing range and calculating sealing parameters; 2) carrying out pre-preparation of sealing operation; 3) carrying out mud jacking and sealing operation; 4) dredging after sealing. According to the method provided by the invention, a gear pump is used for quantitatively feeding mud with pressure, wherein the pressure is stable and controllable, the height of the mud pressed into a brick gas passage can be accurately controlled, and the pressure is kept for a period of time after reaching the height, so that the mud is enabled to sufficiently permeate into a brick joint and a crack for repairing; the situation that the mud is sprayed into a combustor is completely eradicated while effective sealing is performed on the brick gas passage.

Description

technical field [0001] The invention relates to the technical field of thermal repair of coke oven brick gas channels, in particular to a grouting and sealing method for brick gas channels. Background technique [0002] After the coke oven is baked, due to the uneven expansion, the fire mud will fall off, and cracks will appear in the brick gas duct bricks; during the production process, the reversing explosion will cause vibration, which will also cause the fire mud to fall off or cracks in the brick coal gas duct ; If it is not treated, the coke oven gas will leak into the regenerator for combustion, resulting in low temperature of the flue, high temperature of the regenerator, incomplete combustion of the gas and black smoke from the chimney, and serious brick gas. The bricks of the pipes melted. [0003] The traditional hot repair method of brick gas channel is to use compressed air to spray mud into the brick gas channel. The disadvantages of this method are obvious. B...
