Embodiment Construction

[0019] Below in conjunction with the preferred embodiment shown in accompanying drawing, be described in further detail:

[0020] Below by embodiment the present invention is described in further detail, but the present invention is not limited to embodiment:

[0021] See figure 1 , figure 2 , Invention Example 1 Three-channel gas-phase medium gasification nozzle, the gasification medium inlet pipe 1 with a flange is fixedly connected to the corresponding multi-channel nozzle 2, the nozzle 3 and the nozzle 2 are fixed or integrated, Nozzle 3 and nozzle 2 are fixedly connected with equal wall thickness, and the transition is smooth; the inner and outer walls of the nozzle are tapered, and the wall thickness is uniformly thinned by a straight line, which is trapezoidal; the wall thickness of the nozzle at the end of nozzle 3 is 1~ 4mm. Nozzle 3 is made of high temperature resistant alloy material INCONEL600. The water cooling coil 4 is made of HASTELLOY high temperature res...

Abstract

The gas phase medium gasifying nozzle includes gasified medium inlet pipe with flange and corresponding fixed multiple flow channel spray tube with integrated nozzle, and features the equal wall thickness connection between the spray tube and the nozzle with smooth transition, the nozzle with conic outer and inner walls, and nozzle end wall thickness of 1-4 mm. The reasonable arrangement of gasifying nozzles, arced gasifying furnace top and furnace mouth structure forms the optimal flow field and temperature field matching reaching best gasifying effect with effective gas component over 95.5 % and up to 96.3 %. The present invention has prolonged gasifying nozzle life.

Description

Technical field: [0001] The invention mainly relates to the structure and usage method of a gas phase medium gasification nozzle for a non-catalytic oxidation method gasification furnace. Background technique: [0002] Due to the soaring international oil price and the supply shortage caused by the development of deep processing technology for petroleum refined products as raw materials for synthetic ammonia, large-scale synthetic ammonia plants that use light oil, heavy oil, and residual oil as raw materials are facing shortage of raw material sources, rising raw material prices, and declining economic benefits of enterprises. Raw material composition increasingly deviates from the plight of the design composition, resulting in fluctuations in device operation, increased energy consumption, and increased operating costs, making the survival and development of enterprises face a severe situation; on the other hand, with the development of a large number of domestic natural ga...
