Abstract
The present invention discloses one kind of nozzle for efficient tubular reaction desulfurizing device in large coal-burning unit of thermal power plant. The nozzle has the structure comprising a flow stabilizing section, a spraying core, a mixing conic pipe and a speeding pipe. The present invention has the advantages of adaptation to wet limestone-gypsum desulfurizing process, high jamming resistance, simple inner member and small nozzle body resistance loss.
Description
Technical field
The present invention relates to a kind of nozzle that is used for the large-scale coal-firing units gas desulfurization device of thermal power plant, i.e. low resistance cyclonic liquid column type nozzle.
Background technology
China's large coal-fired boiler flue gas desulfurization technique grows out of nothing and has experienced a Tortuous Development Process, domesticly various in the world outstanding desulfur technologies have almost been compiled, but China also lacks design, manufacturing capacity that the commercialization desulfur technology, particularly China that are fit to China's national situation also not exclusively possess the flue gas desulfur device that matches with the coal-fired unit of large thermal power plant.
Summary of the invention
The objective of the invention is to make this smoke eliminator of efficient duct type reaction desulfuration device to promote the use of in thermal power plant large-scale coal-firing units gas desulfurization field with high efficient gas and liquid contacting efficiency for efficient duct type reaction desulfuration device provides a kind of nozzle that is suitable for the large-scale coal-fired unit flue gas characteristic of thermal power plant.
Technical scheme of the present invention is: a kind of efficient duct type reaction desulfuration device give nozzle for liquid, should comprise steady flow segment, spray core, mix Taper Pipe, accelerating tube to nozzle for liquid.Steady flow segment is in the bottom of nozzle, comprises the adpting flange that is positioned at the bottom and the spray core pedestal on top, plays liquid current stabilization, nozzle location and the fixing effect of spray core; The spray core is installed in the spray core pedestal on steady flow segment top, has limit chute and the centre bore with certain lateral angles on the spray core, and the spray core has determined liquid to play spinor and rotary speed; Steady flow segment top connects mixes Taper Pipe, mixes acceleration rotation and secondary mixing that Taper Pipe is finished liquid, mixes Taper Pipe top and connects accelerating tube, the spouting velocity of accelerating tube decision liquid.
The nozzle for liquid of giving of a kind of efficient duct type reaction desulfuration device of this invention has been finished the hydrodynamics Mathematical Modeling, can be used in and instructs industrialization design, makes the nozzle specification form tandem product.
Main technologic parameters of the present invention: nozzle entrance fluid pressure: 0.07MPa～0.1MPa; Nozzle body drag losses: 0.0007MPa～0.002MPa; Jet expansion flow velocity: 11.58～12.21m/s.
The invention has the advantages that: efficient duct type reaction desulfuration device is the gas-liquid contact principle according to the dynamic wave scrubbing technology, in conjunction with the domestic nonferrous metallurgy industry experience that obtained of working power ripple washing technology for many years, and a kind of desulfurizer that forms.The nozzle of this invention makes this desulfurizer successfully be generalized to thermal power plant large-scale coal-firing units gas desulfurization field from industries such as nonferrous metallurgy, building materials, chemical industry, and forms the large-scale coal-firing units gas desulfurization device of a kind of complete and effective thermal power plant.Nozzle based on this invention, formed a kind of efficient duct type reaction desulfuration device, this desulfurizer adapts to the large-scale coal-fired unit flue gas characteristic of thermal power plant, desulfuration efficiency is higher than 95%, can substitute the introduction desulfur technology fully and be applied to the large-scale coal-firing units gas desulfurization of thermal power plant, and the construction cost of this desulfurizer and operating cost are introduced technology and will be reduced approximately 1/3rd, have created necessary condition for the large-scale coal-firing units gas desulfurization technology of thermal power plant realizes production domesticization.

The specific embodiment
A kind of nozzle that is applied to the efficient duct type reaction desulfuration of the large-scale coal-fired unit flue gas of thermal power plant device, this nozzle comprise steady flow segment 1, spray core 2, mix Taper Pipe 3, accelerating tube 4.Steady flow segment 1 is provided with adpting flange 5, spray core pedestal 6, and spray core 2 is provided with centre bore 7 and limit discharge orifice 8.
Liquid by the centre bore 7 of spray core 2 and the throughput of limit chute 8 dispense liquid, makes partially liq obtain initial rotary speed at first through steady flow segment 1 current stabilization; Rotating liquid is further quickened and finishes rotating liquid and mix with straight the preliminary of jetting liquid in mixing Taper Pipe 3, is accelerated to the design current velocity jetting nozzle by accelerating tube 4 liquid and contacts with gas.
