Abstract
The utility model discloses an atomizing nozzle with a double-layered structure for an adjustable Venturi tube, which comprises an internal conical slurry nozzle and a Venturi tube gas nozzle. A slurry inlet tube is arranged on the outer wall of the slurry nozzle, and a threaded surface is arranged on the surface of the inner periphery of the slurry nozzle. The Venturi tube gas nozzle and the slurry nozzle are axially adjustable relatively. Pressure gas after being pressed enters the gas nozzle with an internal conical end, is further compressed, and is gathered with slurry in a conical spraying cavity of the slurry nozzle to form 'liquid-wrapped gas' after being sprayed out from the gas nozzle, the 'liquid-wrapped gas' is broken under the effect of high speed and differential pressure, liquid drops are separated and crushed and is finally sprayed out from the slurry nozzle, so that the slurry is high-efficiently atomized, and the best flue gas desulfurization effect is achieved. The slurry inlet tube is obliquely tangentially communicated with the gas nozzle, the mounting angle of the slurry inlet tube is identical to the spiral angle of a threaded structure, the slurry is further promoted to form natural spiral rotational flow when entering a slurry cavity, and the 'liquid-wrapped gas' is promoted to be formed.
Description
Technical field
The utility model is the atomizer that is applied in the smoke-gas wet desulfurization spraying system, specifically is meant a kind of adjustable type Venturi tube double-decker atomizer.
Background technology
Along with the fast development in thermal power plant, sulfur dioxide (SO2) emissions also are on the increase.And the discharging of sulfur dioxide is to cause air environmental pollution and the increasing one of the main reasons of acid rain.How the coal-burning power plant implements desulfurization project, improves sulfur removal technology, improves desulfuration efficiency, is the effective means of effectively containing sulfur dioxide (SO2) emissions.Practice shows that wet type limestone-gypsum wet process of FGD technology is a kind of high-efficiency desulfurization technology, is adopted by many large coal-fired power plants.
The major advantage of limestone/gypsum method is: the coal scope that is suitable for is wide, desulfuration efficiency is high (during the device Ca/S=1 that has, desulfuration efficiency is greater than 90%), absorbent utilization rate high (can greater than 90%), operation rate high (can reach more than 90%), the reliability high (the most ripe at present flue gas desulfurization technique) of work, desulfurizing agent-lime stone source are abundant and cheap.But the shortcoming of limestone/gypsum method also is apparent in view: the initial investment expense is too high, operating cost is high, floor space is big, system management operation is complicated, the erosion corrosion phenomenon is comparatively serious, accessory substance-gypsum intractable (because the market problem can only be stacked), waste water are more hard to manage.Thereby, improve wet desulphurization efficient, reduce the wet desulphurization energy consumption, reduce the desulfurization operation cost, the great economy meaning is arranged.
In wet desulfurization system, spraying system is its crucial system, and nozzle is the core component of spraying system.Atomizing can provide huge alternate contact area, is a kind of important unit operations.The atomization quality that improves nozzle is to improving desulfuration efficiency, and it is very important to reduce the desulfurization energy consumption.In order to reach the purpose of high-efficiency desulfurization, must build bulky desulfuration spray tower, inner many atomizers of multilayer of installing, and need repeatedly circulation to extract spray column bottom slurries spray to improve the utilization rate of slurries, cost of investment is high.The atomizer that is adopted in the wet desulfuration tower at present is mainly the simple relatively pressure type atomizing nozzle of structure, mainly is divided into solid-cone, hollow cone and fan-shaped conical nozzle.The atomizing effect of this type nozzle is not good, and energy consumption is high, easy blocking.In order further to improve atomizing effect, reduce cost of investment, Operation and Maintenance cost and energy resource consumption, it is very necessary to develop a kind of atomizer of desulfurization efficiently.
Summary of the invention
For overcoming the shortcoming and defect of prior art; The utility model provides a kind of adjustable type Venturi tube double-decker atomizer, can adapt to the different working conditions needs, and its nebulization efficiency is high; Simple in structure, when practicing thrift investment and Operation and Maintenance cost, reduced energy resource consumption.
The utility model is realized through following technical proposals:
A kind of adjusting venturi-type double-decker atomizer; Comprise that the end is that slurries nozzle, the end of inner conical is the gas nozzle of Venturi tube; Said gas nozzle places the inside of slurries nozzle; Have the gap between the inwall of the outer wall of said gas nozzle and slurries nozzle, this gap constitutes the slurries cavity, and the outer wall of said slurries nozzle is provided with slurries and gets into pipe; The diameter of said gas nozzle outlet is slidingly connected through the dual-seal assembly between the tail end of said slurries nozzle and the afterbody of gas nozzle less than the diameter of slurries jet expansion.The related slurries of this patent are lime stone slurry, and related screw fluid is the spiral lime stone slurry.

Gas (like flue gas, steam or air etc.) is inserted in the gas nozzle 2 by air inlet after the air compressor (not shown) improves pressure, regulates the external gas pressure and reach the required parameter value of technology (gas pressure is regulated) between 0.1～0.7MPa.Slurries get into pipe 4 through external high pressure pump (not shown) through slurries and cut sth. askew to entering with the θ angle; Form the nature screw fluid; Send into the slurries cavity interior (slurries pressure can be regulated according to production technology through control valve is set, and pressure can be regulated) of slurries nozzle 1 between 0.2～0.6MPa.
Gas after the pressurization fully quickens ejection in the Venturi tube of gas nozzle 2.Slurries after the pressurization are cut sth. askew to entering with the θ angle through the slurry inlet passage; Form nature screw fluid (spiral slurries); Get in the slurries cavity of slurries nozzle 1; The inner circumferential surface of slurries nozzle 1 is helicitic texture 3-1 (can certainly increase helicitic texture at the external peripheral surface of gas nozzle 2), and screw fluid has further obtained reinforcement under the effect of this above-mentioned helicitic texture.As stated, the gas that improves pressure quickens the ejection back through the Venturi tube of gas nozzle 1 to be mixed with the mode of " gas-in-liquid " with slurries in the slurries cavity, and " gas-in-liquid " breaks under high speed and differential pressure action, thus the littler droplet of generation.
Just can realize this patent preferably as stated.
The foregoing description is the utility model preferred implementation; But the embodiment of the utility model is not restricted to the described embodiments; Other any do not deviate from change, the modification done under spirit and the principle of the utility model, substitutes, combination, simplify; All should be the substitute mode of equivalence, be included within the protection domain of the utility model.
