Abstract
The utility model discloses a novel slag washing water torrent nozzle, which comprises a nozzle body 1, a nozzle inlet 2, a nozzle opening 4 and a nozzle taper hole 3. The inner conicity of the nozzle taper hole 3 is changed into 1:2.1 from a normal designed 1:2.8, which enables the nozzle taper hole to be reduced into Phi 14mm from normal designed Phi 20mm, and the diameter of the nozzle inlet remains the same. Under the condition that the diameter of the nozzle inlet 2 remains the same, the size of the nozzle opening 4 is reduced by changing the conicity of the nozzle taper hole 3, thereby increasing water spray power. The slag washing water torrent nozzle is obvious in using effect, the diameter of the nozzle opening is simultaneously reduced by changing the inner conicity of the nozzle taper hole, and system pressure is increased about 0.3MPa, which fits to discharge slag in the working field, thereby guaranteeing slag troughs to be smooth, and largely reducing labor strength of auxiliary boiler workers. Simultaneously, operation current of pumps is reduced, and thereby power saving effect is obvious.
Description
Technical field
The utility model relates to the flushing cinder water torrent nozzle that a kind of coal-burning boiler hydraulic slag discharging adopts.
Background technology
Coal-burning boiler is station boiler especially, and discharging, the transporting pattern of slag are varied, and hydraulic slag discharging is exactly a kind of typical deslagging mode.After cooled slag enters trench, washed away by the current direction downstream that the torrent nozzle impacts forward.Nozzle connects together by screw thread and elbow, pipeline, and nozzle interior is a bellmouth, and the import large outlet is little, and water is going out the interruption-forming torrent through behind the cohering, and nozzle often is designed to several meters one, can form waterpower and carry.What general Utilities Electric Co. hydraulic slag discharging adopted is the slag runner slag flushing pump, though the water water yield of six meters ejections of torrent nozzle is enough, and the inclined to one side end of system pressure, can not guarantee that slag is in time taken away, cause slag runner obstructed, must improve the pump operation electric current, enlarge power consumption.
Summary of the invention
The utility model is in order to solve the defective that above-mentioned existing flushing cinder water torrent nozzle exists, the transformation of the way also provides a kind of novel flushing cinder water torrent nozzle, thereby has improved system and nozzle outlet pressure, has both guaranteed that slag was in time taken away, slag runner is unimpeded, reduce the pump operation electric current again, reach purpose of saving.
The utility model has adopted following technical scheme:
The novel flushing cinder water of novel flushing cinder water torrent nozzle torrent nozzle comprises nozzle body, jet hole, nozzle inlet and nozzle bore.Nozzle body inwardly projecting orifice hole is an internal taper hole, and the big end of taper hole is a nozzle inlet, and small end is a jet hole, and there is connecting thread in the nozzle body outside.This flushing cinder water torrent nozzle is designed to 1: 2.1 with the nozzle bore internal taper, and making jet hole is Φ 14mm, and the nozzle inlet diameter is Φ 50mm.
This flushing cinder water torrent nozzle result of use is obvious, dwindle jet hole diameter (the Φ 20mm by common design is reduced into Φ 14mm) simultaneously by changing nozzle inner pyramidal hole tapering (changing 1: 2.1 in 1: 2.8 by common design), system pressure has improved about 0.3MPa, can satisfy the working site deslagging uses, guarantee that slag runner is unimpeded, greatly reduce boiler accessory machinery worker's on duty labour intensity, the running current of pump reduces simultaneously, and power savings is remarkable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model
The specific embodiment
As shown in the figure, novel flushing cinder water torrent nozzle comprises nozzle body 1, nozzle inlet 2, jet hole 4 and nozzle taper hole 3.Nozzle taper hole 3 internal tapers change 1: 2.1 into by 1: 2.8 of common design, make the nozzle taper hole also be reduced into Φ 14mm by the Φ 20mm of common design, keep the nozzle inlet diameter constant.Under the constant situation of nozzle inlet 2 diameters, by changing the latus rectum that nozzle taper hole 4 taperings reduce jet hole 3, thereby improve water spray power.In the diagram, dotted line is represented nozzle inner pyramidal hole 4 in the nozzle, after water enters nozzle inlet 2 in the direction of arrows from the right side, produces torrent from 3 ejections of leftmost nozzle mouth, and flow velocity improves generation high speed kinetic energy.
