Abstract
The utility model discloses a low-resistant rotary flow liquid column type sprayer for pipe type reaction desulphurization device, wherein, the sprayer comprises a flow stabilization section, a spraying core, a mixing taper pipe and an accelerating tube. The flow stabilization section is arranged at the low part of the sprayer, and comprises a connecting flange arranged at the bottom and a spraying core base arranged on the upper part and plays a role of liquid flow stabilization, location of the sprayer and fixation of the spraying core; the spraying core is arranged in a spraying core base on the upper part of the flow stabilization section, is provided with an edge flow groove with certain side angle and a central hole and determines the rotation-starting volume of the liquid and the rotary speed; the upper part of the flow stabilization section is connected with the mixing taper pipe, the mixing taper pipe is used to finish the accelerated rotation and secondary mixing of the liquid, the upper part of the mixing taper pipe is connected with the accelerating tube which determines the spraying speed of the liquid. The utility model has the advantages that the sprayer is suitable for the characteristic of the wet type limestone-gypsum desulphurization process, has good anti-blocking performance, no complex internal members and small resistance loss of the sprayer.
Description
Technical field
The utility model 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.
The utility model content
The purpose of this utility model is to make this smoke eliminator with high efficient gas and liquid contacting efficiency of efficient duct type reaction desulfuration device to promote the use of in thermal power plant large-scale coal-firing units gas desulfurization field 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.
The technical solution of the utility model 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 utility model 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 utility model: 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.
Advantage of the present utility model is: 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 utility model 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 utility model, 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.

Fig. 2 is the spray core vertical view of the utility model low resistance cyclonic liquid column type nozzle.
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.
