Abstract

An assembly type thermal treatment heating furnace is provided. The heating furnace is characterized by comprising a polygon-structure furnace body (1), a furnace bottom (2), a cone-frustum-shaped furnace top assembled by sector top plate modules (3) and a circular cover plate (4), three-grid slab type furnace wall modules (5), two-grid slab type furnace wall modules (6) and single-grid slab furnace wall modules (7). Beneficial effects of the heating furnace are that: a preformed equipment module is subjected to integrated thermal treatment in the assembly type thermal treatment heating furnace, and compared with thermal treatment methods of winding local parts with electrically heating sheets, inner fuel oil integrated thermal treatment methods and integrated thermal treatment methods by inputting outer fuel oil flue gas which are frequently-used in engineering at present, the heating furnace has advantages of convenient construction, good stress removing effects, high reutilization rate of thermally insulating materials, less consumed labor and working time, low energy consumption, low cost, high working efficiency, and the like.

Description

Technical field [0001] The invention belongs to the technical field of chemical construction, and relates to an integral heat treatment device of segmented modules in the field assembly welding process of large chemical equipment, in particular to an assembled heat treatment heating furnace and a construction method thereof. Background technique [0002] The scale of chemical equipment continues to develop in the direction of large-scale, ultra-high, ultra-large, and ultra-heavy equipment often requires assembly welding at the construction site. The application of the assembled heat treatment furnace can efficiently complete the post-weld overall heat treatment process of the equipment segmented modules with heat treatment requirements in the field assembly welding, and its application prospects are very broad. [0003] There are many types and specifications of equipment in chemical plants. Due to production process requirements, many equipment require heat treatment to eliminate ...
