[0002] Water film dust collector: It mainly consists of a main cylinder, an upper water inlet tank, a lower overflow hole, and a cleaning hole. Its working principle is: the dust-laden airflow enters the cylinder through the inlet flue. It is a purification device that uses the dust-laden gas to impact the water film formed on the inner wall of the dust collector or other special components by a certain method, so that the dust is captured by the water film and the gas is purified.

[0003] Existing technologies utilize a water film to impact and rotate the gas, ensuring full contact between the water film and the gas to remove dust, thus achieving better dust removal efficiency.

[0004] However, in actual use, water film dust collectors ultimately discharge the water after absorbing dust directly, and the generated wastewater cannot be effectively utilized, resulting in a waste of water resources and increased costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a water film dust collector with an improved spraying mechanism, which solves the problem that in actual use, water film dust collectors ultimately discharge the water after absorbing dust directly, and the generated wastewater cannot be effectively utilized, resulting in water resource waste and increased costs.

[0011] Beneficial effects

[0012] This utility model provides a water film dust collector with an improved spraying mechanism. It offers the following advantages: Through the cooperation of a return pipe, a return pump, and a filtration device, the wastewater generated after dust removal falls into a collection shell. The return pump and water pipe then guide the wastewater into the filtration device, where it is treated and can be reused. This reduces costs and solves the problem that traditional water film dust collectors often directly discharge the water after dust absorption, resulting in ineffective wastewater utilization, water waste, and increased costs.

[0013] By coordinating the nozzle, transmission gears, and servo motor, a fixed frame supports the nozzle. The meshing of the transmission gears and gear rings causes the servo motor to drive the nozzle to rotate on the inner wall of the fixed frame. This allows the sprayed water to rotate rapidly, forming a complete water film. This ensures more thorough contact between the water film and the gas, improving the dust removal effect and solving the problem of insufficient gas dust removal efficiency in existing dust removal devices.

[0017] In practical use, water film dust collectors ultimately discharge the water after absorbing dust directly, and the generated wastewater cannot be effectively utilized, resulting in a waste of water resources and increased costs.

[0018] In view of this, the present invention provides a water film dust collector with an improved spraying mechanism, which solves the problem that in actual use, the water film dust collector ultimately discharges the water after absorbing dust directly, and the generated wastewater cannot be effectively utilized, thus causing waste of water resources and increased costs.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Example 1: By Figure 1-4 It is known that a water film dust collector with an improved spraying mechanism includes a treatment box 1, a spray pipe 2 installed on the inner wall of the treatment box 1, a box cover 4 fixedly connected to the top of the treatment box 1, an air jet ring 10 arranged below the spray pipe 2, a baffle 23 fixedly connected to the bottom of the air jet ring 10, the outer wall of the baffle 23 fixedly connected to the inner wall of the treatment box 1, an exhaust gas pipe 9 connected to the outer wall of the air jet ring 10, the exhaust gas pipe 9 penetrating the treatment box 1, a collection shell 12 arranged below the baffle 23, the outer wall of the collection shell 12 fixedly connected to the lower inner wall of the treatment box 1, a return pipe 14 connected to the bottom of the collection shell 12, a return pump 15 installed at one end of the return pipe 14 penetrating the treatment box 1, and a filter device installed at the end of the return pump 15 away from the return pipe 14. In the specific implementation process, it is worth noting that the lower surface of the nozzle 2 is evenly distributed with spiral atomizing nozzles, the nozzle spacing is 150-200mm, the orifice diameter is 2-4mm, and the spray angle can reach 120°. This can form a uniform and continuous water film on the inner wall of the treatment box 1, improving the dust adsorption efficiency. The top of the treatment box 1 is fixedly connected to the box cover 4 by bolts. The box cover 4 is made of the same material as the treatment box 1, and rubber sealing gaskets are set on the edges to ensure the airtightness of the treatment box 1 and prevent exhaust gas leakage. Exhaust ports are opened on both sides of the top of the box cover 4, and a [missing information - likely a device or equipment] is installed at the exhaust port. A stainless steel filter screen intercepts fine water droplets carried by water mist, reducing water carryover in exhaust gas. The outer wall of the jet ring 10 is connected to an exhaust gas pipe 9 via a flange. The exhaust gas pipe 9 is made of fiberglass and has a diameter of 200-300mm. Its end furthest from the jet ring 10 penetrates the side wall of the treatment chamber 1 and extends to the outside, connecting to the exhaust gas source pipeline. A butterfly valve and flow meter are installed on the exhaust gas pipe 9 to precisely control the intake volume of exhaust gas. A coarse filter screen is also installed at the inlet to intercept large particulate impurities in the exhaust gas, preventing blockage of the jet nozzle. The baffle 23 has a funnel-shaped structure, facilitating the sludge flow. The collection shell 1... The bottom center of tank 2 is connected to a return pipe 14 via a pipe joint. The return pipe 14 is made of UPVC material with a diameter of 100-150mm. A Y-type filter and gate valve are installed on the pipe to filter larger particles in the sewage and prevent pipe blockage. The end of the return pipe 14 away from the collection shell 12 passes through the bottom of the treatment tank 1 and is connected to a return pump 15 via a flange. The return pump 15 is a horizontal centrifugal sewage pump with a rated flow of 10-20m³ / h and a head of 15-25m. Its pump body is made of cast iron and the impeller is made of stainless steel, which can adapt to sewage containing dust. Water medium, the bottom of the return pump 15 is fixedly installed on the concrete foundation by the shock-absorbing pad to reduce vibration and noise during operation. After the gas enters the treatment box 1 through the jet ring 10, the spray pipe 2 will spray water to form a water film, which removes dust from the gas. The wastewater formed will fall into the collection shell 12 through the opening at the bottom of the baffle 23. The wastewater in the collection shell 12 will enter the filter device for treatment through the return pipe 14 and the return pump 15, so as to be reused and reduce costs. The model of the return pump 15 is not limited, as long as it meets the actual use. Furthermore, the filtration device includes a water tank 8, the outer wall of which is fixedly connected to the outer wall of the treatment tank 1, the bottom of which is connected to the output end of the return pump 15, a filter screen 16 fixedly connected to the lower part of the inner wall of the water tank 8, activated carbon 20 being laid on the top of the filter screen 16, and quartz sand 21 being laid on the top of the activated carbon 20. In the specific implementation process, it is worth noting that the water tank 8 can store and purify water, thereby reducing costs. The top of the filter screen 16 is evenly covered with activated carbon 20 with a thickness of 150-200mm. The activated carbon 20 is granular coconut shell activated carbon with a particle size of 2-4mm and a specific surface area ≥1000m² / g. It has extremely strong adsorption performance and can effectively adsorb organic pollutants, odor molecules, and some soluble pigments in sewage, improving the cleanliness of the water. The quartz sand 21 is natural quartz sand with a purity ≥98%. After washing and screening, the layers are laid in stages. The lower layer is fine quartz sand with a particle size of 1-2mm, and the upper layer is coarse quartz sand with a particle size of 2-4mm, forming a gradient filtration structure. Quartz sand has the characteristics of high hardness and good chemical stability, which can further filter out the fine suspended particles and colloidal impurities remaining in the water. At the same time, it supports and protects the activated carbon layer, preventing the activated carbon layer from loosening due to water flow impact. A water-permeable non-woven fabric isolation layer is set above the quartz sand to prevent activated carbon particles from entering the upper filtration structure with the water flow. After the treatment of the filter material, the water can be reused. Furthermore, a water pump 7 is fixedly connected to the top of the water tank 8. The input end of the water pump 7 is connected to an input pipe 22, which passes through the top of the water tank 8. The output end of the water pump 7 is connected to a connecting pipe 5. One end of the connecting pipe 5 passes through the treatment box 1 and is fixedly connected to a fixing block 19. The bottom of the fixing block 19 is rotatably connected to the top of the spray pipe 2 through a sealed bearing. In the specific implementation process, it is worth noting that the fixing block 19 and the nozzle 2 are connected by a sealed bearing. In this way, when the nozzle 2 rotates, the water can enter the nozzle 2 through the fixing block 19, and this can prevent the rotation of the nozzle 2 from being restricted by the connecting pipe 5.

[0021] Example 2: From Figure 1-4 It can be seen that the outer wall of the nozzle 2 is rotatably connected to the fixing frame 6 through the sealed bearing. The outer wall of the fixing frame 6 is fixedly connected to the inner wall of the processing box 1. The outer wall of the nozzle 2 is fixedly connected to the gear ring 18. The outer wall of the gear ring 18 is meshed with the transmission gear 17. The transmission gear 17 passes through the fixing frame 6 through the sealed bearing and is fixedly connected to one end of the processing box 1 to the servo motor 11. The outer wall of the servo motor 11 is fixedly connected to the outer wall of the processing box 1. In the specific implementation process, it is worth noting that the transmission gear 17 is a bevel gear, and the shape of the gear ring 18 on the outer wall of the nozzle 2 is the same as that of the transmission gear 17. The two can mesh together. In this way, when the servo motor 11 is driven, the nozzle 2 is driven to rotate rapidly through the meshing of the transmission gear 17 and the gear ring 18. Under the action of centrifugal force, the sprayed water forms a water film, thereby better removing dust from the gas. The model of the servo motor 11 is not limited, as long as it meets the actual use. Furthermore, a filter screen 13 is fixedly connected to the inner wall of the collection shell 12, a sewage pipe is provided on one side of the outer wall of the collection shell 12, and a baffle plate 3 is provided above the spray pipe 2. The outer wall of the baffle plate 3 is fixedly connected to the upper inner wall of the treatment box 1. In the specific implementation process, it is worth noting that the filter screen 13 is placed at an angle inside the collection shell 12, which can better separate impurities and sewage. Moreover, the sewage is discharged through the drain pipe connected to the outer wall of the collection shell 12, avoiding inconvenience during cleaning. The baffle plate 3 will come into contact with the discharged gas, so that the moisture in the gas will condense on the baffle plate 3 and drip into the collection shell 12, preventing dust from being carried out when the gas is discharged, which would have an impact on the environment.
