[0026] Example:

[0027] This utility model provides a tower-tank separation washing system for spraying circulating washing liquid in a washing tower. This saves washing liquid resources and reduces the risk of blockages in the circulation pipeline, thus improving resource conservation and the reliability of the circulation system. To achieve the system's structural functions, the system includes at least a washing tower body 1, with an air inlet at the bottom and a spray system located at the upper part of the interior; a circulating chemical tank 2, connected to the bottom of the washing tower body 1, for collecting waste liquid discharged from the bottom of the washing tower body 1 and providing a basic reaction vessel for treating the washing liquid; a circulating pump 3 and a return pipe 4 are provided, with the inlet of the circulating pump 3 connected to the circulating chemical tank 2. Figure 1As shown, a return pipe 4 is provided to connect the circulating pump 3 and the spray system. The circulating pump 3 pumps the cleaning solution in the circulating chemical tank 2 back into the spray system, effectively saving cleaning solution resources. To prevent scale formation caused by calcium or magnesium ions from clogging the circulating pipes and affecting the operation of the spray system during long-term operation, a scale inhibitor dosing device is also provided in the system. This device includes a supply tank 9 and a dosing mechanism 8. The dosing mechanism 8 is used to extract the scale inhibitor from the supply tank 9 and add it to the circulating chemical tank 2. By adding scale inhibitor to the circulating system, scale formation in the system pipes during the circulating spray process can be prevented from affecting the normal operation of the system, thus saving resources and improving the operational stability of the circulating system. Alternatively, large particulate impurities in the liquid circulation system can be filtered out by installing an additional filter device in the pipeline system.

[0028] This utility model provides a tower-tank separation washing system. Considering the actual needs of the cleaning fluid, it is not advisable to add too little or too much descaling agent. To control the supply of descaling agent, a dispensing mechanism 8 is provided, including a receiving cavity. Two mutually sealing screws are installed within the receiving cavity. A drive unit is provided on one side of the receiving cavity to drive the two screws to rotate in opposite directions, thereby extruding the descaling agent solvent that moves into the screw gap. The structure can be referenced from a twin-screw extruder. In this design, the receiving cavity is connected to the supply tank 9, and a liquid outlet pipe 11 is provided at the end of the receiving cavity away from the drive unit. The liquid outlet end of the liquid outlet pipe 11 is located at the upper opening of the circulating liquid tank 2. This structure controls the extrusion amount of descaling agent by controlling the rotation amplitude and angle of the screws. Precise control can be achieved by using an encoder or servo motor, or by setting a detection mechanism to detect the conductivity of the cleaning fluid to determine whether the descaling agent is sufficient. This allows for automatic control of the descaling agent supply, facilitating precise control.

[0029] This utility model provides a tower-tank separation washing system. In order to facilitate further cleaning of microorganisms, organic matter and some viruses in the cleaning liquid, the system also includes an ozone generator 7. The pump end of the ozone generator 7 is connected to the liquid circuit system where the spray system is located. The cleaning of these substances is achieved by pumping ozone into the liquid supply system.

[0030] The present invention provides a tower-tank separation type washing system. Considering that ozone is not convenient to be directly released into the environment when it has not fully reacted, it is necessary to decompose the ozone before it is released. Therefore, a metal honeycomb catalyst layer 6 can be provided at the air outlet position above the main body 1 of the washing tower. This catalyst layer is used to catalyze the decomposition of ozone into oxygen. In order to facilitate the removal of some other adsorbable impurities, an activated carbon filter layer can be provided between the metal honeycomb catalyst layer 6. Considering that some ozone may still be emitted from the open environment of the circulating liquid tank 2 when ozone is supplied, the device here also includes a sealing plate 10. The sealing plate 10 is used to seal the opening of the circulating liquid tank 2. An inlet is provided on the sealing plate 10, and the outlet pipe 11 is inserted at the inlet and sealed to prevent air leakage when supplying descaling agent. However, in order to ensure that the circulating liquid tank 2 generates excessive negative pressure to affect the liquid adsorption supply, a gas exchange port can also be provided on the sealing plate 10. A metal honeycomb catalytic filter layer 12 is provided at the gas exchange port to prevent ozone from being emitted directly without treatment.

[0031] This utility model provides a tower-tank separation washing system. To further reduce the impact of scale formation in the pipeline, the system also includes an electromagnetic scale inhibitor 5, which is installed on the return pipe 4. The electromagnetic device generates an alternating electromagnetic field to interfere with the crystallization process of calcium and magnesium ions in the water, causing them to exist in a non-crystalline form instead of depositing on the equipment surface, thereby effectively preventing scale formation.

[0032] This utility model provides a tower-tank separation washing system. To avoid insufficient cleaning fluid or to facilitate the injection of a certain amount of cleaning fluid, a liquid level sensor is installed in the circulating liquid tank 2, and the circulating liquid tank 2 is connected to an external replenishment system. The replenishment system is used to inject cleaning fluid into the circulating liquid tank 2. To periodically replace the cleaning fluid or remove contaminants from the cleaning fluid, a drain pipe is also connected to the bottom of the circulating liquid tank 2. The inlet of the external replenishment system on the circulating liquid tank 2 is positioned at least higher than the inlet of the drain pipe. Both pipes can be opened simultaneously to achieve cleaning of the circulating liquid tank 2 and replacement of the liquid.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
