Abstract
The utility model provides a dust-laden sulphureous flue gas washing purifier which is characterized by comprising a venture tube, wherein at least one first lime water spray nozzle is arranged at the top of the venture tube; the bottom of the venture tube is communicated with a cyclone washing cylinder body through an elbow and a connecting pipe; a cylinder wall girdle is formed in the middle of the cyclone washing cylinder body; and at least two second lime water spray nozzles are arranged in the middle area of the cylinder wall girdle. The dust-laden sulphureous flue gas washing purifier has the advantages as follows: the structure is simple, the flue gas treatment capacity is large, the resistance force is low; 2, a multi-separation effect is achieved, and the process of dust removal and desulfuration with two spurts of lime water is controllable and has a good effect; 3, the dust-laden sulphureous flue gas washing purifier can be widely used in medium and small sized coal burning boilers, lime kilns, brick kilns and other coal burning equipment as a flue gas treatment measure; and 4, a plurality of such dust-laden sulphureous flue gas washing purifiers can be mounted side by side, so as to adapt to equipment with different flue gas volumes.
Description
Technical field
The utility model relates to a kind of dust-laden sulfur-containing smoke gas washing, purifying device.
Background technology
Sulfur dioxide that discharges in the combustion of fossil fuel process and nitrogen oxide form acid rain and have had a strong impact on human life with other secondary pollutions.Therefore, for the washing of flue gas with purify extremely urgent.
For the sulfur dioxide in removing smoke, carried out fume desulphurization method at present in the world, this method is the effective method the most of control acid rain and sulfur dioxide pollution.Its mainstream technology is a wet type lime stone gypsum washing method, and its technological comparative maturity, removal efficiency are high, reliability of technology is good, and still, shortcoming is equipment investment height, system complex, be easy to problem such as obstruction.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure and flue washing device that desulfuration efficiency is high.
In order to achieve the above object; The technical scheme of the utility model has provided a kind of dust-laden sulfur-containing smoke gas washing, purifying device; It is characterized in that: comprise Venturi tube, be provided with at least one first limewash nozzle in the throat of Venturi tube, the bottom of Venturi tube is connected with whirlwind washing cylindrical shell through elbow and adapter; It is with a tight waist that middle part in whirlwind washing cylindrical shell is formed with barrel, and the central region with a tight waist at barrel is furnished with at least two second limewash nozzles.
Further, said at least two second limewash nozzles are tangential distribution around barrel.
On the inwall of said whirlwind washing cylindrical shell, be lined with refractory brick.
The utility model has the advantages that: 1, simple in structure, the smoke treatment amount is big, resistance is low; 2, multiple centrifugation, two strands of limewash spraying and dedustings, sweetening process are controlled, effective; 3, can be widely used in medium and small coal-burning boiler, the limekiln is in the coal combustion equipments such as brickkiln, as the smoke gas treatment means; 4, washer can a plurality of installations arranged side by side, to adapt to the equipment of different exhaust gas volumns.

The specific embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1; A kind of dust-laden sulfur-containing smoke gas washing, purifying device that provides for the utility model; Comprise Venturi tube 1, be provided with at least one first limewash nozzle 6 in the throat of Venturi tube 1, the bottom of Venturi tube 1 is through elbow 3 and take over 4 and be connected with whirlwind washing cylindrical shell 2; On the inwall of whirlwind washing cylindrical shell 2, be lined with refractory brick; It is with a tight waist 7 that middle part in whirlwind washing cylindrical shell 2 is formed with barrel, is furnished with two or four second limewash nozzles in the central region 5 of barrel with a tight waist 7, and the second limewash nozzle is tangential distribution all around at barrel.
The course of work of the utility model is: coarse granule is concentrated; Dust-contained airflow separates when getting into whirlwind washing cylindrical shell 2 once more; Accomplish final separation at the shutter place of separator outlet at last; Clean flue gas gets into back-end ductwork heating surface, the wearing and tearing that alleviate heating surface greatly.
The clarifier of the utility model has two strands of limewash insufflation showerheads; A throat that is located at Venturi tube 1; Another is arranged on the position with a tight waist of whirlwind washing cylindrical shell 2; Can be according to the sulfur content of the content of sulfur dioxide of raw flue gas and equipment outlet flue gas, spray into limewash at different parts respectively and flue gas is washed and make sulfur dioxide form calcium sulfate, play the effect of flue gas desulfurization purified treatment.
