Abstract
The invention relates to a low-resistance high-efficiency bidirectional nozzle for a coal burning boiler smoke wet type electric precipitation device. A direct-through type water inlet hole is formed in the middle of a nozzle body, and two symmetrically-arranged direct-through type water outlet holes are formed in side wall positions below the nozzle body respectively, and the water outlet holes are communicated with the water inlet hole. The low-resistance high-efficiency bidirectional nozzle is low in operation resistance, water mist sprayed by the nozzle in two directions directly covers dust collecting poles at the two sides of the nozzle, the water spraying efficiency is high, and uniformity of a formed water film is good. The operation resistance is low, and the low-resistance high-efficiency bidirectional nozzle is suitable for the coal burning boiler smoke wet type electric precipitation device.
Description
Technical field
The present invention relates to a kind of nozzle for Wet type electric dust-removing device, relate in particular to a kind of high-efficiency low-resistance Bidirectional nozzle for fire coal boiler fume Wet type electric dust-removing device.
Background technology
The typical feature of Wet type electric dust-removing device is that the mode of spraying water by nozzle forms uniform moisture film in dust collecting electrode, and the dust in flue gas, sour gas and other pollutant are absorbed by moisture film, and then discharges Wet type electric dust-removing device.In current Wet type electric dust-removing device, water inlet pipe and nozzle are located immediately at the top of dust collecting electrode, burner design is in the majority with full cone, this arrangement and burner design increase the usage quantity of nozzle, water consumption is large, the formation poor effect of moisture film, has directly affected investment cost, operating cost and the clean-up effect of Wet type electric dust-removing device.In addition, the design type running resistance of some nozzle is high, is unfavorable for the formation of water smoke, has affected the uniformity of moisture film, also causes moisture film cleaning performance not good enough.
The present invention adopts fluid mechanics principle, and a kind of Bidirectional nozzle for fire coal boiler fume Wet type electric dust-removing device of high-efficiency low-resistance is provided.
Summary of the invention
The object of this invention is to provide a kind of high-efficiency low-resistance Bidirectional nozzle for fire coal boiler fume Wet type electric dust-removing device, nozzle body middle part arranges an inlet opening, nozzle body lower sidewalls position arranges respectively two apopores that are arranged symmetrically with, and apopore and inlet opening are connected.Running resistance of the present invention is low, and the water smoke of the two-way ejection of nozzle directly overlays in the dust collecting electrode of nozzle both sides, and water spray efficiency is high, and the good uniformity of the moisture film that forms, is applicable to fire coal boiler fume Wet type electric dust-removing device.
For achieving the above object, arrangement of nozzles of the present invention is on two adjacent dust collecting electrode center line tops, thereby make the water smoke of two two-way ejections of apopore of nozzle body lower sidewalls setting can accurately cover respectively two adjacent dust collecting electrode surfaces, guaranteed water spray efficiency.
Through verification experimental verification, inlet opening of the present invention and apopore are straight-through pattern, and the angle of the center line of inlet opening and two sidewall apopores is all designed to 65-75 degree, guaranteed water smoke diffusion and the coverage effect in dust collecting electrode, and running resistance are low.
Nozzle body of the present invention is cylindrical, and the excircle on nozzle body top is provided with the screw thread being connected with water lines.
Compared with prior art, the present invention has following characteristics:
(1) nozzle body lower sidewalls position arranges respectively two straight-through pattern apopores that are arranged symmetrically with, the water smoke that guarantees two two-way ejections of apopore can accurately cover respectively two adjacent dust collecting electrode surfaces, water spray efficiency is high, the good uniformity of the moisture film that forms.
(2) angle of the center line of inlet opening and apopore is all designed to 65-75 degree, guaranteed water smoke diffusion and the coverage effect in dust collecting electrode, and running resistance is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Fig. 1 is the structural representation of patent of the present invention.
In figure: 1. nozzle body, 2. inlet opening, 3. apopore.
The specific embodiment
Nozzle body (1) middle part of a kind of high-efficiency low-resistance Bidirectional nozzle for fire coal boiler fume Wet type electric dust-removing device of the present invention arranges the inlet opening (2) of a straight-through pattern, nozzle body (1) lower sidewalls position arranges respectively two straight-through pattern apopores (3) that are arranged symmetrically with, and apopore (3) is connected with inlet opening (2).Nozzle body (1) is arranged in two adjacent dust collecting electrode center line tops, inlet opening (2) is all designed to 65-75 degree with the angle of the center line of two sidewall apopores (3), guaranteed the diffusion of water smoke of two-way ejection and the coverage effect in dust collecting electrode, and running resistance is low.When nozzle body (1) is in duty, current are through inlet opening (2), two apopores that are arranged symmetrically with (3) that arrange respectively by nozzle body (1) lower sidewalls position, two-way water spray, water smoke directly overlays in the dust collecting electrode of nozzle body (1) both sides, water spray efficiency is high, and the good uniformity of the moisture film that forms, is applicable to fire coal boiler fume Wet type electric dust-removing device.
Above are only the specific embodiment of the present invention, technical characterictic of the present invention is not limited thereto, and the variation that any those skilled in the art does in the field of the invention or modification all should be included the scope of the claims of the present invention in.
