Description

Technical Field

[0001] This utility model relates to the technical field of drying test chambers, and in particular to a ceramic blank drying test chamber with measurable shrinkage and weight loss. Background Technology

[0002] Denitrification is required in power plant operations. This process uses chemical substances and catalysts to remove nitrogen oxides from flue gas. Commonly used denitrification catalyst units are made of titanium dioxide and are cubic in shape, with square holes neatly arranged along their length. Wet-form catalysts, also known as ceramic wet-forms, require careful drying. Achieving proper drying while controlling shrinkage defects necessitates knowing the shrinkage and weight loss data of wet-form catalysts under different drying temperature and humidity curves. This data supports the optimization of the drying curve, thus requiring a ceramic green body drying test chamber with measurable shrinkage and weight loss. Summary of the Invention

It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] See Figures 1 to 4This invention provides a ceramic preform drying test chamber with measurable shrinkage and weight loss, comprising a temperature and humidity test chamber 1 with an observation window 3, an electronic scale 5 for weight detection inside the temperature and humidity test chamber 1, a bracket 6 on the electronic scale 5, the bracket 6 being composed of two symmetrical steel frames connected together, the steel frame structure being stable and reliable, and air being able to enter the cover plate through a perforated plate and sponge, the bracket ensuring unobstructed airflow to the wet preform catalyst inside the cover plate and bearing the weight, requiring continuous airflow into the chamber during the test to maintain continuous air disturbance inside the chamber, the cover plate preventing the wet preform catalyst inside from being affected by the wind, a cover plate 9 on the bracket 6 for covering the wet preform catalyst, a laser rangefinder 11 on the cover plate 9 for monitoring dimensions, and a display and control device electrically connected to the temperature and humidity test chamber 1, the electronic scale 5, and the laser rangefinder 11 on the temperature and humidity test chamber 1. 2. The display and control device programmatically controls the temperature and humidity parameters inside the experimental chamber, and can monitor and record the temperature and humidity change curves in real time. The weight change monitored by the electronic scale and the size change monitored by the laser rangefinder are fed back to the display and control device. The display and control device is capable of acquiring, retrieving, and analyzing the temperature, humidity, weight, and size change curves over time. The wet catalyst is a cuboid with a fixed shape. During the drying process, the weight and size of the catalyst, as well as the temperature and humidity changes of the drying environment, need to be monitored and recorded in real time. The catalyst sample is placed on the tray and covered with a cover plate. Then the experimental chamber door is closed for the drying test. Two catalyst samples are placed in each test and carried out simultaneously. The weight and size changes are monitored and recorded separately. The shrinkage and weight loss data of the ceramic body under different drying temperature and humidity curves can be obtained, which provides support for optimizing the drying curve.

The laser rangefinder 11 and the electronic scale 5 are provided with wires that pass through the lead wire hole 4 and are electrically connected to the display and control device 2. The lead wire hole allows the wires of the laser rangefinder and the electronic scale to pass through the test chamber and connect to the external display and control device. A heat insulation plug is provided at the lead wire hole to isolate the external temperature and humidity from interference with the temperature and humidity inside the chamber.

[0020] A protective cover 10 is provided at the top of the cover plate 9, and a laser rangefinder 11 is disposed on the protective cover 10. A perforation is provided at the top of the cover plate 9 to allow the laser rangefinder 11 to pass through.
