The cleaning device also comprises a liquid supply system, wherein the liquid supply system supplies liquid required by the cleaning spray head 3; when the gas exhausted by the experiment is acid mist gas, the liquid supply system can be provided with alkaline liquid or clear water to flush the main pipeline 2 so as to prevent harmful gas from remaining or attaching in the main pipeline 2, thereby reducing potential safety hazards of a laboratory and reducing the probability of occurrence of safety accidents of the laboratory. In summary, the liquid provided by the liquid supply system may be a neutralizing liquid capable of neutralizing the gas exhausted from the experiment, or may be clean water to clean and adsorb the gas exhausted from the experiment. In the utility model, the liquid supply system is a water tank which is arranged at the top end of the acid mist purifying tower.
The branch pipes 11 are alternately arranged with the cleaning head 3 at intervals, whereby the liquid sprayed from the cleaning head 3 is prevented from being splashed into the branch pipes 11.
In order to further prevent the liquid sprayed by the cleaning nozzle 3 from splashing into the branch pipe 11, the spray range angle of the cleaning nozzle 3 is selected to be 40 to 100 °. The spray range depends on the diameter of the main pipe 2 and the spacing between two adjacent branch pipes 11, the larger the spacing between two adjacent branch pipes 11 is, the larger the spray range angle can be selected, and the larger the diameter of the main pipe 2 is, the larger the spray range angle can be selected.
