Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with specific embodiments.

[0027] In the present invention, 4 kinds of construction tools are used: sandblasting machine, electric sprayer, long-arm extrusion type smearing device, long-handled vibration flattener; two materials are used: interface treatment agent and explosion-proof, wear-resistant and refractory smear ; A quick boiler lining repair method is provided, which replaces the traditional boiler lining repair method. The specific implementation steps are as follows:

[0028] (1) Preparation of construction equipment: sandblasting machine, electric sprayer, long-arm extrusion type coating device, long-handle vibrating flattener, Party B usually does maintenance work, and has a special warehouse for storage, and can be put into use immediately if needed;

[0029] (2) Preparation of interface treatment agent and wear-resistant and refractory smear: the prepared finished interface...

Abstract

The invention belongs to the field of unshaped refractory application and particularly relates to a quick repair method for a boiler lining material. After cleaning and roughening processing are conducted on a damaged part through a sanding device, an interface processing agent is sprayed at the damaged position through an electric sprayer, later the damaged position is coated with wearproof plastic refractory in an extruded mode through an extruded type long arm coating device, the wearproof plastic refractory is compacted and flattened through a long handle vibration flattener, and fast boiler heating and slow boiler heating are conducted in two stages afterwards. According to the quick repair method for the boiler lining material, a traditional repairing method for a traditional boiler lining is replaced, and the boiler lining can be efficiently repaired with high quality.

Description

technical field [0001] The invention belongs to the application field of monolithic refractory materials, and in particular relates to a quick repair method for boiler lining. Background technique [0002] The boiler lining rapid repair method involved in the present invention is mainly applied to the repair of damaged boiler partial lining materials. [0003] Taking the circulating fluidized bed boiler in the thermal power industry as an example, during the use of the boiler, due to wear, thermal shock and other reasons, the wear-resistant and refractory lining material will be partially damaged. The components are worn or oxidized, further causing problems such as air leakage in the steam pipeline. [0004] After the boiler lining material is partially damaged, the maintenance process needs to shut down the furnace, which will cause great economic losses. For example, if a 15MW (gas production capacity is about 45t / h) boiler is shut down for 24 hours, the power generation...
