[0019] The utility model will be further explained and described below in combination with the drawings:

[0020] Embodiment, see Figs. 1-2The utility model provides an aluminum electrolysis workshop intelligent dust suppression device of travelling crane, including travelling crane girder 1, high temperature resistant branch pipeline 2 and spray head 3, high temperature resistant branch pipeline 2 is arranged at the bottom of travelling crane girder 1 two sides respectively, and the bottom of high temperature resistant branch pipeline 2 is provided with spray head 3, and high temperature resistant branch pipeline 2 is connected together with the bottom of water tank 4 through main pipeline 5, and is provided with booster pump 7 on main pipeline 5, and the middle part of the bottom of travelling crane girder 1 is provided with smoke dust collector 8, and smoke dust collector 8 is connected together with smoke dust collection and analysis device 9 through line, and smoke dust collection and analysis device 9 is arranged at the top of travelling crane girder 1 and is connected together with controller through line.

[0025] The main pipeline 5 is made of high-temperature resistant pipeline.

[0026] In the above description, the smoke dust collector can accurately detect the smoke density in different areas according to the requirements of the workshop or precise control.

[0027] In the above description, the smoke dust collection and analysis device will compare the smoke density in different areas in real time, and the water pump will be pumped into the spray head in the area above the set value, and the smoke density signal will be converted into a water pressure signal transmitted to the controller, so as to realize precise control.

[0028] In the above description, the spray head belongs to a nanometer atomization device, which can atomize water into a size comparable to the size of smoke particles, and the high-density, fine-particle water mist will fully combine with the smoke and particulate matter in the air, thereby achieving the best dust suppression effect.

[0029] In the above description, the high-temperature resistant water pipe has a long service life and high-temperature resistance, preventing damage from long-term heating above the electrolytic cell.

[0031] In actual use, first, the crane girder is divided into several regions, the support of the smoke dust collector is installed under the crane girder after the region is determined, and then the smoke dust collector is fixed on the welded support. Then the smoke dust collection and analysis device is installed above the crane girder, the signal of the smoke dust collector is connected to the smoke dust collection and analysis device through the signal line, and the received signal is analyzed and processed in the smoke dust collection and analysis device and is converted into a water pressure signal and is input into the controller; the controller and the water tank are installed above the crane girder on the aluminum tapping end side, and the purpose is to avoid the influence on the aluminum electrolysis cell production caused by accidental water leakage of the water tank. The controller installed beside the water tank controls the water pressure in the high-temperature-resistant water pipe, so as to realize the regional water atomization control. After the atomized water in the spray head reacts with the flue gas, the smoke dust collection device also continuously collects data, and if the smoke dust concentration in the whole region changes, the corresponding controller will adjust the pressure of the regional spray head to realize real-time processing.

[0032] In addition, in order to avoid the problem of water shortage or overflow during the water injection process, the water tank sub-limit alarm installed in the water tank will issue a warning reminder, and the on-site operator will add water in time according to the actual situation, and when the water level is higher than the upper limit, the water injection action will be automatically cut off.

[0033] Through the control idea of detection-analysis-control-detection, a closed loop is realized, the regional concentration of smoke dust can be effectively controlled and accurately controlled, and the working environment of the aluminum electrolysis workshop and the safe operation of the aluminum electrolysis cell are improved.

[0034] The smoke gas and solid particulate matter generated in the aluminum electrolysis workshop during the pole changing operation process can be combined with the mist water to inhibit the flying and reduce environmental pollution; the smoke dust collection device has the function of collecting regional smoke dust concentration, realizes accurate monitoring and inhibits unorganized emission of smoke dust; the electrolytic cell is in a long-term power-on state, the mist spray head and the high-temperature-resistant water pipe can ensure that the insulation part will not short circuit due to water; the water storage tank is installed to the aluminum tapping end, which can effectively avoid the water leakage hidden danger, and the water tank has a limiting alarm function, which prompts to add water when the water level in the tank is lower than the lower limit, and automatically cuts off the water injection action when the upper limit is reached.
