Description

Technical Field

[0001] The utility model relates to the technical field of operation and maintenance tools for water coal slurry gasifiers, and is an internal diameter measuring tool for water coal slurry gasifiers. Background Technique

[0002] After a water coal slurry gasifier operates for a period of time, the internal diameter of the gasifier is measured to judge the ablation condition of the furnace bricks (ablation rate, ablation amount), so as to judge whether the furnace bricks can continue to be used. A box ruler is often used to measure the internal diameter of the water coal slurry gasifier. The accuracy of the measured data is of great significance for judging the ablation condition of the furnace bricks of the gasifier. At present, the measurement method has the following three main defects: (1) The inner surface of the furnace bricks is uneven due to ablation. When measuring, the contact area between the two ends of the box ruler and the furnace bricks is small, and the measurement of the box ruler is greatly affected by the measurement position, resulting in measurement value deviation; (2) Since the inner diameter of the gasifier is large, the measuring box ruler will deflect downward when stretched for measurement, which is likely to cause measurement deviation; (3) During the measurement process, it is easy to occur that the measurement points at both ends are not in the same plane, resulting in a larger measured data. Summary of the Invention

[0003] The utility model provides an internal diameter measuring tool for a water coal slurry gasifier, which overcomes the above-mentioned deficiencies of the prior art and can effectively solve the problem that the measurement accuracy needs to be improved when using a box ruler to measure the internal diameter of the gasifier.
