However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1-9 This is an embodiment of the present utility model, which provides a spray purification dust collector, including a spray tower 1 and a purification tower 10. The spray tower 1 has a spray air guide pipe 2 fixedly installed in its inner cavity, a dust inlet pipe head 3 fixedly installed on the outside of the spray tower 1 near the top, and an external nozzle 4 fixedly installed on the top of the spray tower 1.

[0030] The system features a dual-tower structure consisting of a spray tower 1 and a purification tower 10, along with a spray duct 2 and a dust inlet pipe 3. This structure enables the initial collection of dust and the guidance of airflow. The annular array design of the external nozzles 4 prevents fiber blockage and facilitates cleaning and maintenance. It also enhances atomization and improves dust wetting efficiency.

[0031] Specifically, a first observation window 5 is fixedly installed on the outside of the spray tower 1, and a circulating water tank 6 is fixedly installed at the bottom of the spray tower 1 and the purification tower 10 through a bracket.

[0032] The first observation window 5 facilitates real-time monitoring of the internal operating status of the spray tower 1, while the circulating water tank 6, through its integrated support design, enables centralized collection and recycling of sewage, reducing water waste and lowering maintenance frequency.

[0033] Furthermore, a water inlet pipe 7 is fixedly installed on one side of the spray tower 1, and a water pump 8 is fixedly installed inside the circulating water tank 6. The end of the water inlet pipe 7 is fixedly connected to the water pump 8.

[0034] The connection between the water inlet pipe 7 and the water pump 8 forms a closed-loop water circulation system, ensuring continuous water supply to the external nozzle 4 and preventing spray interruption due to blockage. At the same time, the circulating water is reused after filtration, reducing operating costs.

[0035] Preferably, a first air duct 9 is fixedly installed on the top of the spray tower 1, and one end of the first air duct 9 is fixedly connected to the outside of the purification tower 10 and they are interconnected.

[0036] The first duct 9 connects the spray tower 1 and the purification tower 10, allowing the escaped dust to enter the secondary purification stage. Through centrifugal motion, particulate matter is further separated, improving the overall dust removal efficiency and meeting environmental emission standards.

[0037] Furthermore, a purification air duct 11 is fixedly installed inside the purification tower 10, a second observation window 12 is fixedly installed on the outside of the purification tower 10, a second air duct 13 is fixedly installed on the top of the purification tower 10, a negative pressure fan 14 is fixedly installed at the end of the second air duct 13, and an exhaust port 15 is opened on the outside of the negative pressure fan 14.

[0038] Among them, the purification duct 11 and the second observation window 12 optimize the airflow distribution and visualization management in the purification tower 10, the second duct 13 guides the purified air to be discharged, multi-stage treatment ensures that the emitted gas meets the standards, the negative pressure fan 14 provides stable negative pressure power, enabling the dust to be efficiently sucked into the system, the exhaust port 15 discharges clean air in a directional manner, and at the same time, by controlling the airflow speed, dust is suppressed, the risk of dust explosion is reduced, and intrinsic safety is achieved.

[0039] Furthermore, a drain pipe 16 is provided on the outside of the circulating water tank 6, and external nozzles 4 are arranged in a ring array on the top of the spray tower 1.

[0040] Among them, the drain outlet 16 facilitates the regular cleaning of sediment in the circulating water tank 6, and the annular layout of the external nozzle 4 enhances the atomization coverage, ensuring long-term stable operation of the system and reducing manual intervention.

[0041] During operation, under the suction of the negative pressure fan 14, the dust-laden gas enters the spray tower 1 through the dust inlet pipe 3. The annular spray system of the external nozzle 4 fully atomizes the circulating water, causing the dust and fibers to wet and settle. The pre-purified airflow carries the escaped particles into the purification tower 10 through the first air duct 9, and achieves secondary purification through the centrifugal separation of the purification guide pipe 11. The settled sludge is collected in the circulating water tank 6 for filtration and then re-supplied to the spray system by the water pump 8. Finally, the clean gas is discharged from the exhaust port 15 in compliance with standards. The entire process is monitored in real time through the first observation window 5 and the second observation window 12. The sewage outlet 16 periodically discharges the sediment, forming a highly efficient closed-loop dust removal system.

[0042] In summary, through the collaborative design of the dual towers 1 (spray tower 1) and 10 (purification tower 10), combined with the annular array arrangement of external nozzles 4 and the airflow guidance of the spray duct 2, efficient dust collection and fiber anti-clogging are achieved. The circulating water tank 6 and the water pump 8 form a closed-loop water circulation system, which, together with the sewage outlet 16, reduces maintenance costs. The multi-stage purification process driven by the negative pressure fan 14, through the linkage of the first duct 9, the purification duct 11, and the second duct 13, significantly improves dust removal efficiency. At the same time, the first observation window 5 and the second observation window 12 enable operation visualization. This structure combines explosion-proof safety with the effects of effectively suppressing dust, recycling resources, and easy cleaning of the external nozzles 4. It effectively solves the clogging problem under high dust conditions, meets environmental emission standards, and reduces operating costs.
