Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a device for separating and collecting harmful ultrafine dust in industrial waste gas. Background Technology

[0002] Industrial waste gas refers to harmful gases generated and emitted into the atmosphere during industrial production processes. Its main components include particulate matter, volatile organic compounds (VOCs), sulfur dioxide (SO2), nitrogen oxides (NOx), and carbon monoxide (CO). These gases negatively impact the environment and human health, causing air pollution, respiratory diseases, and contributing to climate change. Therefore, measures to control industrial waste gas include adopting waste gas treatment facilities, optimizing production processes, and implementing relevant laws and regulations to reduce harmful emissions. The separation and collection of harmful ultrafine dust typically employs various methods, including high-efficiency particulate filters (such as HEPA filters) for particle capture, electrostatic precipitators using electrostatic adsorption to separate charged dust, wet scrubbing using water mist to settle dust, airflow separators using airflow to change direction and speed to separate particles, and dust collection systems for direct collection at the dust source.

[0003] However, existing waste gas treatment methods mostly employ a single approach, resulting in insufficient treatment of harmful substances in the waste gas. Some harmful dust will still escape, thus affecting air quality and human health.

[0004] Therefore, this utility model provides a device for separating and collecting harmful ultrafine dust in industrial exhaust gas to solve the above-mentioned problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] The system utilizes a combination of filtration, spraying, and cyclone dust collectors.

The atomizing nozzles are spirally distributed along the coils, ensuring comprehensive spraying, avoiding dead zones, and improving settling efficiency. Finally, the exhaust gas enters the filter membrane to filter out the tiny particles. This multi-faceted separation and treatment of harmful dust in the exhaust gas prevents harmful dust from escaping and affecting air quality and human health. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides a device for separating and collecting harmful ultrafine dust in industrial exhaust gas, such as... Figures 1-4 As shown, a device for separating and collecting harmful ultrafine dust in industrial exhaust gas includes a cylinder 1. A through groove is provided on the inner bottom wall of the cylinder 1. A cyclone dust collector 2 is fixedly connected inside the through groove. A spray assembly is fixedly connected to the inner side wall of the cylinder 1. An exhaust pipe 3 is fixedly connected to the middle of the upper surface of the cylinder 1. A filter assembly is fixedly connected to one end of the exhaust pipe 3.

[0025] The filter assembly includes a housing 4, one side of which is fixedly connected to one end of the exhaust pipe 3. A mounting plate 5 is fixedly connected to the top of the inner wall of the housing 4, and a filter membrane 6 is fixedly connected to the inner side of the mounting plate 5. A guide plate 7 is fixedly connected to one side of the lower surface of the housing 4, and a first dust collection box 8 is fixedly connected to the other side of the lower surface of the housing 4. When the exhaust gas enters the filter membrane 6, the filter membrane 6 intercepts and filters the tiny particles in it. The particles then fall above the guide plate 7 and slide down at an inclined angle into the first dust collection box 8 for collection and treatment, which can further improve the treatment effect of harmful dust.

[0026] A duct 9 is fixedly connected to the upper surface of the housing 4. A fan 10 is fixedly connected to one end of the duct 9. An outlet pipe 11 is fixedly connected to the outlet of the fan 10. When the fan 10 is started, the filtered exhaust gas can be drawn out through the duct 9 and the outlet pipe 11.

[0027] The spray assembly includes a ventilation disc 12, the outer surface of which is fixedly connected to the middle of the inner wall of the cylinder 1. A coil 13 is fixedly connected to the lower surface of the ventilation disc 12, and an atomizing nozzle 14 is fixedly connected to the lower surface of the coil 13. The atomizing nozzle 14 is spirally distributed along the coil 13. The atomizing nozzle 14 sprays purified water to settle finer and more viscous dust particles in the exhaust gas. It can effectively ensure the multi-faceted nature of the spray, avoid spray dead zones, and improve the settling effect.

[0028] A water pump 15 is fixedly connected to one end of the coil 13, and a water inlet pipe 16 is fixedly connected to the input end of the water pump 15. When the water pump 15 is started, purified water can be drawn into the coil 13 through the water inlet pipe 16 and sprayed out through the atomizing nozzle 14.

[0029] One end of the inlet pipe 16 is fixedly connected to the sewage treatment tank 17. A water collection pipe 18 is fixedly connected to one side of the upper surface of the sewage treatment tank 17. The water collection pipe 18 can collect the water sprayed by the atomizing nozzle 14 into the sewage treatment tank 17. After being purified by the sewage treatment tank 17, the water can be recycled by the water pump 15, which can improve resource utilization and reduce cost consumption.

[0030] An air inlet pipe 19 is fixedly connected to one side of the cyclone dust collector 2. The air inlet pipe 19 extends out of the cylinder 1. A second dust collection box 20 is fixedly installed on the lower surface of the cyclone dust collector 2. The air inlet pipe 19 facilitates the entry of exhaust gas. Under the centrifugal force of the cyclone dust collector 2, heavier dust particles fall into the second dust collection box 20 for subsequent cleaning.

[0031] Working steps: First, the exhaust gas enters the cyclone dust collector 2 through the inlet pipe 19. The airflow is forced to rotate around the central axis in the cyclone dust collector 2, forming centrifugal force. Under the action of centrifugal force, the heavier dust particles are forced to move outward and collide with the inner wall of the dust collector. Then, due to gravity, they gradually sink into the second dust collection box 20, thus achieving separation. Next, after centrifugal separation, the purified gas enters the cylinder 1 through the upper end of the cyclone dust collector 2. The water pump 15 is started to draw purified water from the sewage treatment tank 17 into the coil 13 through the water inlet pipe 16. The water is sprayed out through the atomizing nozzle 14 to settle the finer and more viscous dust particles in the exhaust gas. Next, the exhaust gas enters the filter membrane 6. The filter membrane 6 intercepts and filters the tiny particles in it. Then, the particles fall above the guide plate 7 and slide down at its tilt angle into the first dust collection box 8. Finally, the fan 10 draws the filtered exhaust gas out through the air duct 9 and the outlet pipe 11.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
