Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings of the specification. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0022] Such as figure 1 As shown, the cylinder section annular seam heating mechanism (heating of the inner wall of the cylinder section annular seam) of the pressure vessel of the present invention includes a natural gas delivery pipe 1, a carbon steel heating arc tube 2 and a burner 3.

[0023] The two ends of the carbon steel heating arc tube 2 are provided with blocking plates 4, and the central part of the carbon steel heating arc tube 2 is in communication with one end of the natural gas delivery pipe 1. One end is connected to the natural gas source;

[0024] The carbon steel heating arc tube 2 suspends and surrounds the inner wall heated by the circumferenti...

Abstract

The invention discloses a heating mechanism for the ring seam of the cylinder joint of a pressure vessel. The two ends of the carbon steel heating arc tube are provided with blocking plates, and the central part of the carbon steel heating arc tube is connected to one end of the natural gas delivery pipe. Unicom, the other end of the natural gas delivery pipe is connected to the natural gas source; the carbon steel heating arc tube is suspended and surrounds the inner wall or outer wall heated by the ring seam of the pressure vessel, and the outer wall of the carbon steel heating arc tube is provided with etc. Ventilation holes distributed at intervals, burners are installed on each vent hole, and the fire direction of each burner is perpendicular to the heating surface of the corresponding ring seam of the cylinder joint; the bottom of the burner is provided with an arc-shaped gap, and the two ends of the arc-shaped gap The part is welded on the carbon steel heating arc tube on both sides of the corresponding vent hole. The invention ensures that the heating effect of the ring seam of the cylinder joint is uniform, improves the heating quality, has a simple structure, is easy to realize, and has good application prospects.

Description

Technical field [0001] The invention relates to a cylinder section annular seam heating mechanism of a pressure vessel, belonging to the technical field of heating equipment. Background technique [0002] At present, many chemical plants and power plants need to install many large pressure vessels. In the production process of pressure vessels, heating is required for the butt joint of the cylinder section, the surfacing of the inner wall of the cylinder section, and the welding of the pipe flange. Especially for the circumferential seam heating of the inner wall of the adjacent cylinder section of the pressure vessel, it is heated by the combustion of natural gas in the pipeline. The natural gas heating equipment on the market, due to the small natural gas burner nozzle, cannot fully contact the air, and the combustion is insufficient , And insufficient combustion does not produce a large amount of harmful gases, such as carbon monoxide, which also affects the heating effect, a...
