Embodiment Construction
[0015] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:
[0016] refer to figure 1 and figure 2 As shown, the oxygen-enriched continuous gasification mixing device for a fixed-bed gas furnace in this embodiment includes a closed tank body 1 whose main body is cylindrical and whose bottom is in an inverted conical shape. 1. The steam input pipe 2 and the oxygen-enriched air input pipe 3 are distributed symmetrically in the direction of the tangent line of the inner wall. The steam input pipe 2 and the oxygen-enriched air input pipe 3 communicate with the airtight tank body 1, and the inverted conical bottom of the airtight tank body 1 An output pipe 4 communicating with the airtight tank body 1 is installed in the center. In addition, in order to enhance the safety and explosion-proof performance of the oxygen-enriched continuous gasification mixing device of the fixed-bed gas furnace, an explosion-proof ...

The invention discloses a rich oxygen continuous gasification mixing device and technology for a gas furnace of a fixed bed gas furnace, wherein the device comprises a closed tank, a steam input pipe installed on the closed tank and communicated with the same, an oxygen-enriched air input pipe and an oxygen-enriched air output pipe, an exit of the steam input pipe and an exit of the oxygen-enriched air input pipe are distributed along a tangential direction of an inner wall of the closed tank in an reversed symmetrical form. In this way, when the steam and the oxygen-enriched air respectively enter the closed tank along the tangential direction of the inner wall of the closed tank, the two kinds of gases will be buffered and spirally mixed, so that the gases can be mixed more completely and uniformly, and gasification efficiency of the steam and the oxygen-enriched air is improved.
Description
technical field [0001] The invention relates to an oxygen-enriched continuous gasification technology of a fixed-bed gas furnace, in particular to a mixing process of an oxygen-enriched continuous gasification mixing device for a fixed-bed gas furnace. Background technique [0002] At present, domestic gas furnaces are classified according to bed layers, and are generally divided into fixed bed gas furnaces, entrained bed gas furnaces and fluidized bed gas furnaces. Among them, when the fixed-bed gas furnace performs oxygen-enriched gasification, it generally needs to continuously gasify the steam and oxygen-enriched air input into the central tube at the bottom, so as to improve the combustion efficiency of the fixed-bed gas furnace and save energy. The current oxygen-enriched continuous gasification technology of the fixed-bed gas furnace is to pass the pipeline with steam and the pipeline with oxygen-enriched air respectively into the furnace bottom central tube of the fi...
