Problems solved by technology

[0003] The current technology is to re-weld the steel plate box at the leaking part, and fill the interior with refractory mud for temporary repair. After the repair is completed, there will be no more smoke leakage in a short time, and there will be secondary leakage after long-term operation. Due to the gap between the refractory brick at the real leakage point If it is not blocked, the formed condensed acid and dilute acid will dissolve the refractory material and form acid mud, and the leak point will produce acid mud accumulation and expansion, causing the steel plate to crack

Embodiment Construction

[0018] The principles and features of the present invention are described below, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0019] The described method for repairing leakage of a furnace, the method for repairing a leakage of a furnace, is characterized in that it includes the following steps:

[0020] (1) Clean up and repair the leaks and damages on the surface of the steel shell of the equipment; the cleaning process includes acid mud manual cleaning or mechanical cleaning. After cleaning, neutralize and clean if necessary. Clear water;

[0021] (2) Enter the interior of the equipment, repair and fill the gaps or falling parts of the refractory bricks with a composite repair plugging agent to ensure that there is no leakage in the gaps of the internal refractory bricks when the external glue is injected; if the gaps between the refractory bricks are not greater than 5mm, the leaka...

Abstract

The invention relates to the technical field of repair for breakage and leakage of sulfuric acid system boiling furnaces, roasters and sulfur burning furnaces in the industries of smelting and the like, in particular to a repair method for the furnace kiln leakage. Materials are injected into an equipment interlayer through a glue injection pump, the materials flow between flame retardant layers under certain pressure, the gaps between the flame retardant layers are filled, after the gaps are filled to a certain degree, refractory brick gaps in equipment are repaired, the source of furnace gas leakage is really repaired, and therefore the long-term operation of the equipment is ensured. According to the repair method, materials are saved, operation is convenient, cost is low, and the service life of the equipment is prolonged.

Description

technical field [0001] The invention relates to the technical field of repairing damage and leakage of fluidized fluidized furnaces, roasting furnaces, and sulfur incineration furnaces of sulfuric acid systems in smelting and other industries, and in particular relates to a method for repairing leakage of furnaces and kilns. Background technique [0002] In industrial production, fluidized fluidized furnaces (roasting furnaces), sulfur incinerators, and other equipment with more than two layers of anti-corrosion and insulation layers have leakage problems during the production process, which seriously pollute the equipment and the surrounding environment, and there are also problems in safe production. Due to the sulfur content of the internal flue gas, when the weather and temperature change greatly, sublimated sulfur or sulfuric acid will be formed inside the steel plate of the furnace body, causing corrosion and leakage of the steel body of the equipment. The structure of...
