Integral modular structure of industrial furnace and construction method

Abstract

The invention discloses an integral modular structure of an industrial furnace and a construction method. The integral modular structure comprises a main body part and accessory equipment and accessories. The main body part of the integral modular structure of the industrial furnace comprises a radiation section modular structure, a convection segment, a radiation furnace pipe, a crossing pipe for connecting a convection furnace pipe with the radiation furnace pipe and a supporting hanging system for the radiation furnace pipe and the crossing pipe. The accessory equipment and accessories comprise a chimney, a waste heat boiler, a steam pocket, a draught fan, an ash ejector, parts of platform and ladder, an instrument and a cable of the instrument. The method comprises the steps that the main body part of an integral module of the industrial furnace and the accessory equipment and accessories of the integral module of the industrial furnace are manufactured and assembled in a workshop, integrally transported and integrally mounted to be in place. Integral modular design, workshop modular manufacturing, integral assembly, integral transportation and field integral mounting to be in place are adopted in the industrial furnace; the construction difficulty is reduced, the manufacturing precision and the construction schedule are ensured, the labor cost of site operation is low, the construction period is short, and construction is safe.

Description

technical field [0001] The invention relates to the field of industrial furnaces for petrochemical equipment, and more specifically, relates to an integral modular structure and a construction method of an industrial furnace. Background technique [0002] Industrial furnaces (including various heating furnaces, reforming furnaces and ethylene cracking furnaces, the same below) are one of the most important equipment in petrochemical plants. Their structures are relatively large and complex, and their temperatures are relatively high during operation. The construction period of the industrial furnace can directly affect the construction and construction period of the entire device, and the manufacturing and construction quality of the industrial furnace also directly affect the operational performance indicators of the entire furnace or device. [0003] At present, the construction methods of existing industrial furnaces are roughly as follows: the steel structure of the radi...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, because the radiation section cannot be modularized, the construction of the industrial furnace can only be completed on site. The current construction method of the industrial furnace has the following disadvantages: 1. A large number of personnel need to be stationed at the construction site of the industrial furnace for a long time, and the labor cost is high

2. Limited by the conditions of the industrial furnace construction site, it is difficult to carry out a large number of cross operations, and the construction period of the industrial furnace is long

3. A lot of work on the industrial furnace construction site requires high-altitude operations, which is dangerous and costly for safety measures

4. The large number of large-scale machinery and tools on the industrial furnace site is huge, the cost is high, and it is difficult to manage

5. Limited by the construction conditions of the industrial furnace site, it is difficult to guarantee the construction quality of the industrial furnace, the installation accuracy is relatively low, and subsequent maintenance requires a lot of manpower and material resources

6. The on-site construction of industrial furnaces is affected by weather, climate and seasons, and it is difficult to ensure the continuity of construction
