FIG. 3 is a schematic illustration of the effect of air flow on slurry.
One end of the connecting rod 5 passes through the slurry outlet passage 22 to be fixedly connected with the housing base 1, and the other end extends outwards from the slurry outlet 221. The baffle 6 is connected to one end of the connecting rod 5 extending out of the slurry outlet 221 and is blocked in the discharging direction of the slurry outlet 221 to change the spraying direction of the slurry.
Because baffle 6 is connected at the one end that connecting rod 5 stretches out the thick liquid mouth 221 and keeps off in the play thick liquid direction of thick liquid mouth 221, from the thick liquid mouth 221 spun thick liquid is impacted, the rotary-cut by the rotatory air current of gas outlet 231 spun, thick liquid is evenly stirred fast, then, the thick liquid after stirring strikes baffle 6 again, makes the thick liquid obtain further atomizing, so, just so can realize better atomization effect to high viscosity thick liquid for the spraying is more even, and the spraying effect is better.
In addition, the high-viscosity slurry atomization nozzle for the inner wall of the boiler tube of the thermal power generating unit provided by the embodiment is convenient for spraying high-viscosity slurry, is certainly applicable to spraying low-viscosity slurry, can be used for spraying pipelines, and can be widely applied to similar aspects needing spraying or pneumatic stirring in the food processing industry or other industrial fields, and the application range is wider.
For the shell base 1, a gas chamber 3 and a slurry making chamber 9 are also arranged in the shell base 1, and a slurry inlet 8 and a gas inlet 7 are arranged at the tail end 4 of the shell base 1, which is back to the spraying end 2; the slurry inlet 8 is communicated with a slurry pipeline (not shown), and the gas inlet 7 is communicated with a high-pressure gas pipeline (not shown); the pulp inlet 8 is communicated with the pulp outlet channel 22 through the pulp making chamber 9, and the apertures of the pulp inlet 8 and the pulp making chamber 9 are the same, so that the pulp blockage caused by diameter change is avoided; the gas inlet 7 communicates with a number of gas outlet channels 23 via gas chambers 3.

The working process of spraying the high-viscosity slurry atomization nozzle on the inner wall of the pipeline for the inner wall of the boiler tube of the thermal power generating unit is as follows:
the inner wall of a boiler tube of a thermal power generating unit integrally extends into a pipeline by using a high-viscosity slurry atomization nozzle, and the telescopic length of a connecting rod 5 is adjusted according to the size of the required spraying circular ring area;
feeding the slurry from the slurry inlet 8 into the slurry producing chamber 9 by high pressure and reaching the slurry outlet 221 along the slurry outlet passage 22 communicating with the slurry producing chamber 9;
high-pressure gas is introduced into the gas chamber 3 from the gas inlet 7, and is finally sprayed out from the gas outlet 231, and the gas sprayed out from each gas outlet 231 is matched together to form spiral gas flow as the gas outlet 231 is arranged in a deflection way towards the axis of the slurry outlet 221, and the slurry sprayed out from the slurry outlet 221 is rotary-cut, so that the slurry is rotary-cut;
the slurry after rotary cutting is collided on a baffle plate 6 with a certain distance from the front end of the slurry outlet 221, and is sprayed and atomized again;
the sprayed slurry is sprayed to the inner wall of the pipeline through a gap between the baffle 6 and the spraying end 2;
uniformly moving high-viscosity slurry atomization spray heads for the inner wall of a boiler tube of a thermal power unit in a pipeline to ensure that the high-viscosity slurry atomization spray heads for the inner wall of the boiler tube of the thermal power unit realize uniform spraying on all parts of the inner wall of the pipeline;
in addition, the following beneficial effects of the high-viscosity slurry atomization nozzle for the inner wall of the boiler tube of the thermal power generating unit in the embodiment are supplemented:
in the prior art, in order to obtain better atomization of the slurry, the slurry outlet 221 needs to be formed in a contracted shape to control the amount of the slurry sprayed, because if the amount of the slurry sprayed is relatively large, it may not be possible to obtain better atomization of all the slurry. However, in the high-viscosity slurry atomization nozzle for the inner wall of the boiler tube of the thermal power generating unit in the embodiment, due to the design of the baffle 6, the slurry with high viscosity can be well atomized outside the slurry outlet 221, so the slurry outlet 221 can be made into a flat tubular shape, compared with the contracted slurry outlet 221, the flat tubular slurry outlet 221 is not easy to be blocked, and therefore, the size of the high-viscosity slurry atomization nozzle for the inner wall of the boiler tube of the thermal power generating unit can be made smaller, so as to be suitable for spraying the inner wall of a small-size pipeline.
Moreover, as the air inlet 7 is connected with the high-pressure air inlet pipeline, the slurry inlet 8 is connected with the slurry inlet pipeline, so that the lengths of the high-pressure air inlet pipeline and the slurry inlet pipeline can be adjusted according to the needs, the propelling depth of the high-viscosity slurry atomizing nozzle for the inner wall of the boiler tube of the thermal power generating unit is increased, and the spraying device is suitable for spraying the inner wall of a longer pipeline.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the application.
