Embodiment Construction

[0014] 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.

[0015] A method for repairing leakage at the top of a kiln is characterized in that it comprises the following steps:

[0016] (1) Carry out all cutting and dismantling of the furnace roof steel shell;

[0017] (2) Remove the furnace top insulation brick or diatomite layer;

[0018] (3) Purging and cleaning the surface of the refractory brick of the furnace body, including manual cleaning or mechanical cleaning, air flow purging or other gas purging and cleaning, and the surface is required to be free of ash and other foreign matter;

[0019] (4) Fill the gaps of refractory bricks with composite repair and plugging agent, and pour a layer of thickness 20-400mm on the furnace roof as a whole. After curing, lay a layer of light-weight thermal insulation material...

Abstract

The invention relates to the technical field of damage and leakage restoration on the tops of a sulphuric acid system boiling furnace, a roasting furnace and a sulfur burning furnace in industries of smelting and the like, in particular to a furnace kiln top leakage restoration method. The overall restoration is carried out through composite restoration leakage blocking agents for furnace top fire-resistant brick layers, then, a layer of substitute heat insulation layer is cast on an integral furnace top by light-weight heat insulation materials, a furnace air leakage source is really restored for ensuring the long-period operation of equipment, under the conditions that the materials are saved, the maintenance time is reduced, the operation is convenient, and the cost is reduced, the real leakage points of the equipment can be effectively restored, the anti-corrosion performance of the equipment is improved, the service life of the equipment is prolonged, and the long-time normal operation of the equipment is ensured.

Description

technical field [0001] The invention relates to the technical field of repairing damage and leakage at the top of sulfuric acid systems in smelting and other industries, and in particular relates to a method for repairing leakage at the top of a kiln. 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 fluidized fluidized furnace (roasting furnace) and sulfur burning furnace ...
