Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmental protection treatment technology for smelting enterprises, specifically a water-filter type environmental protection dust removal device. Background Technology
[0002] Metallurgical furnaces are the main production and high-pollution equipment in non-ferrous metallurgical enterprises. The production process involves adding raw materials such as ore, coke, and flux, along with fuel, from the top of the furnace. After a series of physicochemical changes including heating, reduction, melting, slagging, carburizing, and desulfurization, the molten iron produced is discharged from the top of the furnace. The resulting gas, after dust removal, is used as fuel for hot blast stoves, heating furnaces, coke ovens, and boilers. Because blast furnace ironmaking has good technical and economic indicators, a simple process, high output, high labor productivity, and low energy consumption, the molten metal in the metallurgical furnace accumulates to a certain level in the hearth, and is then released through an opening. Operating continuously throughout the day, the furnace continuously emits dust, averaging about 2.5 kg of dust per ton of metal, causing significant environmental pollution. During the discharge process, a large amount of "yellow smoke," consisting of various toxic and harmful dust pollutants, is generated, which is difficult to degrade once it floats in the air. The dust generated by the metallurgical furnace accounts for about 30% of the total pollutants produced on-site; therefore, dust collection is directly related to the effectiveness of on-site dust control. The flue gas at the scene is characterized by high temperature, strong jetting force, large jetting volume, and a wide range of dust particle sizes.
[0003] In existing technologies, such as the Chinese patent application CN216149294U entitled "A Self-priming Water Filtration Dust Removal Device," the device includes a vehicle body, a fixed limiting cylinder, a water tank, a suction nozzle, an exhaust fan, a vent pipe, and a blower. The fixed limiting cylinder is located at the upper end of the vehicle body, near the rear end. The suction nozzle is connected to the exhaust port of the exhaust fan, and the suction nozzle and exhaust fan are located at the front end of the fixed limiting cylinder. The water tank is placed inside the fixed limiting cylinder, which has corresponding inlet and outlet ports. The exhaust fan's outlet is connected to the water tank, which contains a filter plate. The blower is located at the upper end of the vehicle body, near the front end. The vent pipe is located at the front end of the vehicle body and connected to the blower. The suction nozzle is located above the blower. Through this method, the self-priming water filtration dust removal device of this invention has a good dust removal effect and allows for effective recycling of the water resources in the water tank.
[0004] In existing technologies for dust filtration, the contact area between dust and water is limited by the air pipe, making it difficult for dust to fully contact the water flow when it enters the water, resulting in a low dust filtration efficiency and consequently, poor dust removal performance of the dust removal device.
[0005] Therefore, it is necessary to provide a water-filter type environmentally friendly dust removal device to solve the above-mentioned technical problems. Utility Model Content
[0006] The purpose of this utility model is to overcome the defects and deficiencies of the existing technology and provide a water-filtering environmentally friendly dust removal device. This device solves the problem that the contact area between the dust and the water flow is limited by the air pipe, making it difficult for the dust to fully contact the water flow when it enters the water flow, resulting in a low dust filtration effect and thus a poor dust removal effect.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A water-filtration environmentally friendly dust removal device includes a support platform, a filter box fixedly connected to the top of the support platform, a water tank fixedly connected to the top of the filter box, a No. 1 motor fixedly mounted on the top of the filter box, a rotating frame fixedly sleeved on the output shaft of the No. 1 motor, a mud-water separation cage fixedly sleeved inside the rotating frame, a conveying ring fixedly sleeved on the top of the filter box, an atomizing nozzle fixedly mounted at the bottom of the conveying ring, a water pump fixedly mounted on the top of the filter box, a water supply pipe fixedly sleeved on the side of the water pump, a mixing mechanism inside the water tank, an air duct fixedly sleeved on the side of the filter box, a control host fixedly mounted on the top of the support platform, an air supply mechanism inside the air duct, a protective mechanism at the top of the air duct, an exhaust mechanism on the side of the filter box, and a moving mechanism at the bottom of the support platform.
[0009] The number of atomizing nozzles is several, and the several atomizing nozzles are evenly distributed above the mud-water separation cage.
[0010] The mixing mechanism includes a fourth motor, which is fixedly installed on the top of the water tank, and a stirring arm is fixedly sleeved on the output shaft of the fourth motor.
[0011] The air supply mechanism includes a second motor, which is fixedly installed at the bottom of the air duct. The protective mechanism of the second motor includes an air inlet hopper, which is fixedly sleeved on the top of the air duct. A protective net is fixedly sleeved inside the air inlet hopper.
[0012] The exhaust mechanism includes an exhaust hood, which is fixedly sleeved on the side of the filter box. A No. 3 motor is fixedly installed inside the exhaust hood, and a No. 2 fan blade is fixedly sleeved on the output shaft of the No. 3 motor.
[0013] The moving mechanism includes a support column, which is fixedly connected to the bottom of the support platform, and a sliding wheel is installed at the bottom of the support column.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This utility model has a reasonable structural design. By setting up atomizing nozzles, when the smoke and dust are filtered and purified by water filtration, the smoke and dust are introduced into the interior of the filter box through the air duct. At this time, the No. 1 motor and water pump are started, so that the No. 1 motor drives the mud-water separation cage to rotate rapidly. The rotating mud-water separation cage can absorb the smoke and dust. At the same time, the water pump can draw water from the water tank and spray it evenly onto the top of the mud-water separation cage through the atomizing nozzles, thereby achieving a full contact effect between the smoke and dust and the water flow, thus improving the water filtration and purification effect of the smoke and dust.
[0016] By setting up a mixing mechanism, when flue gas and dust need to be purified by water filtration, hydrogen peroxide solution is injected into the water tank. At this time, motor No. 4 is started, which drives the hydrogen peroxide solution and water flow to mix quickly through the stirring arm. This allows the water flow to filter the sulfide gas in the flue gas, thereby improving the filtration and purification effect of the flue gas and thus improving the practicality of the dust removal device.

[0022] 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 scope of protection of the present utility model.
[0023] See appendix Figure 1-3 ;
[0024] A water-filtering environmentally friendly dust removal device includes a support platform 1, a filter box 2 fixedly connected to the top of the support platform 1, a water tank 3 fixedly connected to the top of the filter box 2, a No. 1 motor 4 fixedly installed on the top of the filter box 2, a rotating frame 5 fixedly sleeved on the output shaft of the No. 1 motor 4, a mud-water separation cage 6 fixedly sleeved inside the rotating frame 5, a conveying ring 7 fixedly sleeved on the top of the filter box 2, an atomizing nozzle 8 fixedly installed at the bottom of the conveying ring 7, a water pump 9 fixedly installed on the top of the filter box 2, a water supply pipe 10 fixedly sleeved on the side of the water pump 9, a mixing mechanism 11 inside the water tank 3, an air duct 12 fixedly sleeved on the side of the filter box 2, a control host 13 fixedly installed on the top of the support platform 1, an air supply mechanism 14 inside the air duct 12, a protective mechanism 15 at the top of the air duct 12, an exhaust mechanism 16 on the side of the filter box 2, and a moving mechanism 17 at the bottom of the support platform 1.
[0025] There are several atomizing nozzles 8, which are evenly distributed above the mud-water separation cage 6. By setting the atomizing nozzles 8, when the dust is filtered and purified by water filtration, the dust is input into the filter box 2 through the air duct 12. At this time, the No. 1 motor 4 and the water pump 9 are started, so that the No. 1 motor 4 drives the mud-water separation cage 6 to rotate rapidly. The rotating mud-water separation cage 6 can absorb the dust. At the same time, the water pump 9 can absorb the water flow in the water tank 3 and spray it evenly onto the top of the mud-water separation cage 6 through the atomizing nozzles 8, thereby achieving a full contact effect between the dust and the water flow, and thus improving the water filtration and purification effect of the dust.
[0026] The mixing mechanism 11 includes a fourth motor 111, which is fixedly installed on the top of the water tank 3. A stirring arm 112 is fixedly sleeved on the output shaft of the fourth motor 111. By setting up the mixing mechanism 11, when flue gas water filtration purification is required, hydrogen peroxide solution is injected into the water tank 3. At this time, the fourth motor 111 is started, so that the fourth motor 111 can drive the hydrogen peroxide solution and water flow to mix quickly through the stirring arm 112. This allows the water flow to filter the sulfide gas in the flue gas, thereby improving the filtration and purification effect of the flue gas, that is, improving the practicality of the dust removal device.
[0027] The air supply mechanism 14 includes a second motor 141, which is fixedly installed at the bottom of the air duct 12. A first fan blade 142 is fixedly sleeved on the output shaft of the second motor 141. By setting up the air supply mechanism 14, when filtering smoke and dust, the second motor 141 is started, which drives the first fan blade 142 to rotate rapidly, thereby creating a negative pressure inside the air duct 12. This allows the smoke and dust outside the filter box 2 to quickly enter the filter box 2 through the air duct 12, thereby improving the absorption effect of external smoke and dust, that is, improving the purification speed of smoke and dust.
[0028] The protective mechanism 15 includes an air inlet hopper 151, which is fixedly sleeved on the top of the air duct 12. A protective net 152 is fixedly sleeved inside the air inlet hopper 151. By setting up the protective mechanism 15, when dust is being absorbed, the protective net 152 can filter the airflow entering the air inlet hopper 151, thus preventing damage to the ventilation components caused by foreign objects entering the air inlet hopper 151, thereby improving the protection effect of the internal components of the dust removal device.
[0029] The exhaust mechanism 16 includes an exhaust hood 161, which is fixedly sleeved on the side of the filter box 2. A third motor 162 is fixedly installed inside the exhaust hood 161, and a second fan blade 163 is fixedly sleeved on the output shaft of the third motor 162. By setting the exhaust mechanism 16, when the dust filtration is finished, the third motor 162 is started, which drives the second fan blade 163 to rotate rapidly, thereby driving the filtered airflow inside the filter box 2 to be quickly discharged to the outside of the filter box 2, thereby improving the filtration efficiency of the dust removal device.
[0030] The moving mechanism 17 includes a support column 171, which is fixedly connected to the bottom of the support platform 1. A sliding wheel 172 is installed at the bottom of the support column 171. By setting up the moving mechanism 17, when the dust removal device needs to be moved and transported, the support platform 1 is pushed, so that the sliding wheel 172 can drive the support platform 1 to move horizontally through the support column 171, that is, drive the filter box 2 to move horizontally, thereby achieving the effect of moving and transporting the dust removal device, and thus bringing convenience to the adjustment of the working position of the dust removal device.
[0031] The working principle of the above structure is as follows:
[0032] Step 1: First, during the flue gas water filtration purification, the flue gas is introduced into the filter box 2 through duct 12. At this time, motor 4 and water pump 9 are started, causing motor 4 to drive the mud-water separation cage 6 to rotate rapidly. This rotating cage absorbs the flue gas, while water pump 9 draws water from the water tank 3 and sprays it evenly onto the top of the mud-water separation cage 6 through atomizing nozzles 8. This achieves sufficient contact between the flue gas and water, improving the water filtration purification effect. When further flue gas water filtration purification is needed, hydrogen peroxide solution is injected into the water tank 3. Then, motor 4 and water pump 9 are started. Motor 111 enables the fourth motor 111 to drive the hydrogen peroxide solution and water flow to mix rapidly through the stirring arm 112, so that the water flow can filter the sulfur gas in the dust, thereby improving the dust filtration and purification effect, that is, improving the practicality of the dust removal device. When the dust is being filtered, the second motor 141 is started, which drives the first fan blade 142 to rotate rapidly, thereby creating a negative pressure inside the air duct 12, allowing the dust outside the filter box 2 to quickly enter the filter box 2 through the air duct 12, thereby improving the absorption effect of the external dust, that is, improving the dust purification speed.
[0033] Step 2: During dust collection, the protective net 152 filters the airflow entering the air inlet hopper 151, preventing damage to ventilation components caused by foreign objects entering the air inlet hopper 151. This improves the protection of the internal components of the dust collector. When the dust filtration is complete, the No. 3 motor 162 is started, which drives the No. 2 fan blade 163 to rotate rapidly. This allows the filtered airflow inside the filter box 2 to be quickly discharged to the outside of the filter box 2, thereby improving the filtration efficiency of the dust collector. When the dust collector needs to be moved, the support platform 1 is pushed, allowing the sliding wheel 172 to move horizontally through the support column 171, which in turn moves the filter box 2 horizontally. This achieves the effect of moving and conveying the dust collector, and facilitates the adjustment of the working position of the dust collector.
[0034] Compared with related technologies, the water-filter type environmentally friendly dust removal device provided by this utility model has the following beneficial effects:
[0035] By setting up atomizing nozzles 8, when performing water filtration purification of smoke and dust, the smoke and dust are input into the interior of the filter box 2 through the air duct 12. At this time, the No. 1 motor 4 and the water pump 9 are started, so that the No. 1 motor 4 drives the mud-water separation cage 6 to rotate rapidly, thereby allowing the rotating mud-water separation cage 6 to absorb the smoke and dust. At the same time, the water pump 9 absorbs the water flow inside the water tank 3 and then sprays it evenly onto the top of the mud-water separation cage 6 through the atomizing nozzles 8, thereby achieving a full contact effect between the smoke and dust and the water flow, thus improving the water filtration purification effect of the smoke and dust.
