Problems solved by technology
[0003] The horizontal swing axis and the vertical swing axis of the traditional spout that can be adjusted simultaneously vertically and horizontally are not on the same plane, so that the two sets of adjustment linkages for horizontal and vertical swing restrict each other. Due to the complex trajectory of the nozzle swing motion, not only is it difficult to optimize and adjust the combustion, but it is also impossible to realize frequent adjustment of remote electric control, and it is difficult to undertake the role of steam temperature adjustment.

Embodiment Construction
[0026] The following are examples of the present invention, which are only used to explain the present invention and not to limit.
[0027] see Figure 1-2 , a one-way freely adjustable two-way swing spout of the present invention consists of a spout sleeve 2, a spout 3, a spout shaft 4, a connecting pin 5, a spout rotation pin 6, a universal coupling 7 and a spout sleeve rotation pin 8, etc. composition;
[0028] The spout 3 is connected to the spout sleeve 2 through a pair of symmetrical spout rotation pins 6, and the spout 3 can rotate around the axis of the spout rotation pin 6 relative to the spout sleeve 2; The spout sleeve rotation pin 8 is connected to the air duct 1, and the spout sleeve 2 can rotate around the axis of the spout sleeve rotation pin 8 relative to the air duct 1; the axis of the spout rotation pin 6 and the spout sleeve rotation pin The axes of the shafts 8 are in the same plane and are perpendicular to each other;
[0029] Both ends of the spout sha...

The invention discloses a unidirectional free-adjustment bi-directional swinging spraying nozzle. The unidirectional free-adjustment bi-directional swinging spraying nozzle includes a spraying nozzle sleeve, a spraying nozzle body, a spraying nozzle shaft rod, spraying nozzle rotation pin shafts and spraying nozzle sleeve rotation pin shafts; the spraying nozzle body is connected to the spraying nozzle sleeve through a pair of symmetrical spraying nozzle rotation pin shafts; the spraying nozzle rotates around axes of the spraying nozzle rotation pin shafts with respect to the spraying nozzle sleeve; the spraying nozzle sleeve is connected to an air duct through a pair of symmetrical spraying nozzle sleeve rotation pin shafts; the spraying nozzle sleeve rotates around axes of the spraying nozzle sleeve rotation pin shafts with respect to the air duct; the axes of the spraying nozzle rotation pin shafts and the axes of the spraying nozzle sleeve rotation pin shafts are in the same plane, and are perpendicular to each other; two ends of the spraying nozzle shaft rod are fixed on the spraying nozzle, is located in a zero position before the spraying nozzle swings and is adjusted, an axis of the spraying nozzle shaft rod and the axes of the spraying nozzle sleeve rotation pin shafts coincide. The spraying nozzle can achieve vertical and horizontal swinging adjustment, and can ensure free adjustment in the other direction after adjustment in one direction is finished.
Description
technical field [0001] The invention belongs to the field of pulverized coal combustion equipment, in particular to a two-way swing nozzle with one-way free adjustment. Background technique [0002] For tangential combustion pulverized coal boilers, swingable secondary air and exhaust air nozzles are often used. The vertical swing of the secondary air and overfired air nozzles can adjust the height of the flame center, thereby controlling the temperature of the flue gas at the furnace outlet, and adjusting the temperature of the main steam and reheated steam. The horizontal swing of the secondary air and overburning air nozzles can adjust the diameter of the imaginary tangential circle, thereby adjusting the rotating dynamic field, optimizing combustion, reducing NOx generation, improving combustion efficiency and reducing high-temperature corrosion and coking of the water wall. Because a small change in the horizontal swing adjustment angle of the secondary air nozzle can ...
