Description

Technical Field

[0001] The utility model relates to the technical field of sulfur melters, in particular to a steam pipeline structure of a sulfur melter. Background Art

[0002] In the coking industry, the sulfur melter used for coke oven gas desulfurization, also called the sulfur melting heater, is mainly used to heat the sulfur foam from the foam tank to generate sulfur for extraction, so as to achieve the final gas desulfurization effect.

[0003] A steam pipe is installed at the steam inlet pipe of an existing sulfur melter. However, during use of the existing steam pipe structure, due to the short pipe stroke, the steam just delivered will quickly enter the steam inlet pipe from the pipe. Then the steam temperature at this time is too high, which can easily cause cracks or even breakage at the steam inlet pipe of the sulfur melter, reducing the service life of the equipment.

[0012] Furthermore, the top outer wall of the threaded square sleeve is welded to the bottom outer wall of the arc-shaped lifting block.

[0013] The beneficial effects of the utility model are:

[0014] 1. The steam pipe assembly designed by the utility model, the steam just delivered from the steam main pipe will be dispersed by the steam dispersion pipe, then enter the two serpentine pipes, and finally flow from the two serpentine pipes into the steam convergence pipe to converge into the steam inlet pipe, which effectively prolongs the journey of the steam just delivered into the steam inlet pipe.
