Problems solved by technology

[0003] With the expansion of demand for catalyst production capacity, an effective measure is to increase the throughput of the roaster, correspondingly, it is necessary to increase the diameter or size of the roaster, and the larger the diameter or size of the roaster, the lower the temperature in the roaster. The more difficult it is to ensure the stability, which will affect the roasting effect and the qualification rate of the catalyst

Abstract

The invention provides a roasting furnace which comprises a barrel, a feeding unit, a discharging unit and combustors, the feeding unit and the discharging unit are communicated with the barrel, the barrel is provided with a plurality of cavities, and the combustors are arranged in the cavities. According to the roasting furnace, the multiple cavities are adopted, the characteristic of large treatment capacity can be achieved at the same time, the requirement for controlling the roasting temperature can be met under the condition that the treatment capacity is large, and the requirement for the roasting technology is met.

Description

technical field [0001] The invention relates to a roasting furnace, in particular to a large-scale multi-burner roasting furnace used for catalyst roasting process. Background technique [0002] The roasting process is almost the last link in the preparation of all solid catalysts and catalyst carriers. The roasting process is often carried out in a roaster. Nowadays, the energy consumption of roasters accounts for more than 50% of the total energy consumption of the catalyst industry. During the calcination process, the calcination temperature and calcination time have an important influence on the structural properties, phase, grain size, surface acidity, strength, specific surface area and pore distribution of the catalyst, and ultimately affect the overall performance of the catalyst, and the calcination effect will directly affect The final product pass rate of the catalyst. Therefore, there are strict requirements on the calcination temperature and calcination time in...
