Description

Technical Field

[0001] This utility model relates to the field of decomposition furnace technology, specifically a large-capacity decomposition furnace. Background Technology

[0002] Under the national strategy of dual control of energy consumption, the government and industry departments will continue to strengthen the management of high-energy-consuming enterprises and limit total energy consumption, further increasing the pressure on cement companies. Therefore, promoting and implementing innovative energy-saving and emission-reduction technologies has become one of the main ways to reduce carbon emissions and energy consumption. As the calcination system plays a crucial role in cement production, the company has continuously upgraded its calcination system in recent years to improve production and reduce energy consumption. Although production capacity has increased to some extent, improving cement quality is particularly important under the current market conditions.

[0003] A relevant reference is Chinese utility model patent CN116972639A, which discloses a decomposition furnace. This furnace includes a furnace body and connecting pipes for air, coal, feed, and rotary kilns. The coal, feed, and rotary kiln pipes have identical structures. The coal supply pipe includes a first, second, and third connecting pipe connected to the furnace body. The ends of the first and second connecting pipes that are close to each other are inclined, forming a conical notch between them that is identical to the structure of the third connecting pipe. The coal supply pipe also includes a first locking mechanism for locking the third connecting pipe to the first connecting pipe and a second locking mechanism for locking the third connecting pipe to the second connecting pipe. This invention aims to reduce the precision requirements for the reserved dimensions of the pipelines.

[0004] Based on the aforementioned patent searches and the findings of existing equipment, cement production plays a crucial role in the calcination system. While continuous upgrades to the calcination system to increase production and reduce costs have led to some capacity improvements, the current market conditions make cement quality improvement paramount. The existing three-line kiln system, dedicated to producing 52.5 cement, faces limitations in quality improvement under current market competition, failing to meet the production requirements of the new era. These limitations in cement quality improvement have impacted the operation of the equipment. Utility Model Content
