Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, and in particular to an environmentally friendly pipeline-type industrial spray adsorption waste gas purification device. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life, especially from chemical plants, steel plants, pharmaceutical plants, coking plants, and oil refineries. The waste gas emitted by these plants has a strong odor, seriously pollutes the environment, and affects human health. Environmental protection pipeline industrial spray adsorption waste gas purification devices are a type of device for treating waste gas.

[0003] A search revealed Chinese patent publication number CN216935129U, which discloses an environmentally friendly pipeline-type industrial spray adsorption waste gas purification device. The device includes a purification pipe, a self-cleaning component, and an adsorption component. The self-cleaning component is installed at the top of the purification pipe and specifically consists of a filter plate A, an air inlet, an exhaust fan, a drive shaft, bearings, a scraper, a slot, magnet A, and magnet B. An exhaust fan is installed at the top of the purification pipe and connected to the scraper via the drive shaft and bearings. The scraper is positioned outside the filter plate A, allowing the exhaust fan's rotation to drive the scraper across the filter plate surface via the drive shaft and bearings, eliminating the need for frequent disassembly and cleaning of the filter plate A, thus enhancing its practicality. A chemical tank is installed at the top of the purification pipe, and an atomizing nozzle is inserted into the top of the purification pipe to spray the filtered waste gas with chemical solution for purification. The gas is then filtered and adsorbed by the filter plate B and the adsorber, removing toxic substances before being discharged.

[0004] However, in actual use, it was found that due to the high gas velocity of the exhaust gas in the pipeline, the mixing time between the atomizing nozzle and the exhaust gas was short, which reduced the mixing effect of the medicine and the exhaust gas. Utility Model Content

[0005] The purpose of this invention is to solve the problem of poor mixing effect between medicinal water and waste gas in the existing technology, and to propose an environmentally friendly pipeline industrial spray adsorption waste gas purification device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly pipeline-type industrial spray adsorption waste gas purification device includes a connecting pipe running through the front and rear, and an installation pipe fixedly connected in the cavity of the connecting pipe, with both ends of the installation pipe being bell-shaped. A baffle is vertically connected inside the installation pipe, and a nozzle is provided on the baffle, with the spray direction of the nozzle parallel to the plane of the baffle. A driving unit is used to drive the baffle to move vertically, and when the baffle moves, the nozzle sprays out a mist of liquid.

[0008] To facilitate the lifting and lowering of the baffle, preferably, the driving unit includes a guide cylinder, which is fixedly connected to the outer wall of the mounting tube. A guide rod is slidably connected to the guide cylinder, and the baffle is fixedly connected to the bottom of the guide rod.

[0009] To facilitate the delivery of liquid medicine to the nozzle, a water pump is fixedly connected to the outer wall of the mounting pipe. The output end of the water pump is connected to the guide cylinder through a pipe. The side wall of the guide cylinder is fixedly connected to the nozzle through a telescopic pipe. A liquid storage tank is provided inside the cavity of the connecting pipe. The input end of the water pump is connected to the liquid storage tank through a pipe.

[0010] To facilitate the lifting and lowering of the guide rod, preferably, the guide rod extends into the guide cylinder and is fixedly connected to a piston, which is connected to the inner wall of the guide cylinder by a return spring.

[0011] To facilitate the filtration of exhaust gas, preferably, a filter plate is detachably installed inside the connecting pipe.

[0012] To facilitate the scraping of impurities on the filter plate, preferably, a fixing plate is fixedly connected to the inner wall of the connecting pipe, and a rotating shaft is rotatably connected to the fixing plate. One end of the rotating shaft is provided with a turbine blade, and the other end of the rotating shaft is fixedly connected with a scraper, which is in contact with the surface of the filter plate.

[0013] Compared with the prior art, this utility model provides an environmentally friendly pipeline-type industrial spray adsorption waste gas purification device, which has the following beneficial effects:

[0014] 1. This environmental protection pipeline industrial spray adsorption exhaust gas purification device uses two sets of lifting and moving baffles, which are staggered. On the one hand, it can block the airflow in the installation pipe channel, so that the baffles can turbulent the industrial exhaust gas, thereby slowing down the exhaust gas flow rate and enhancing the mixing effect of the atomized liquid and exhaust gas. On the other hand, it can also make the exhaust gas stay in the channel for a longer time, thereby increasing the contact time between the atomized water and the exhaust gas.

[0015] 2. This environmental protection pipeline-type industrial spray adsorption waste gas purification device uses industrial waste gas to flow in the connecting pipe, which drives the turbine blades to rotate. The turbine blades then drive the rotating shaft to rotate, which in turn drives the scraper to rotate. During the rotation of the scraper, the filter plate can be automatically cleaned, reducing the need for manual maintenance and improving the practicality and economy of the equipment.

[0016] The parts of this device not covered are the same as or can be implemented using existing technology. On the one hand, this utility model can block the airflow in the installation pipe channel, so that its baffle can turbulent the industrial waste gas, thereby slowing down the waste gas flow rate and enhancing the mixing effect of the atomized liquid and the waste gas. On the other hand, it can also make the waste gas stay in the channel for a longer time, thereby increasing the contact time between the atomized water and the waste gas. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example:

[0025] Reference Figures 1-4An environmentally friendly pipeline-type industrial spray adsorption waste gas purification device includes a connecting pipe 1 that runs through the front and rear. The two ends of the connecting pipe 1 are respectively provided with a funnel-shaped inlet and outlet, and these two ends can be connected to external pipelines. An installation pipe 2 is also provided in the cavity of the connecting pipe 1, and the two ends of the installation pipe 2 are bell-shaped.

[0026] The bell-shaped installation pipe 2 is designed to centrally transport industrial waste gas within the pipeline and enhance the guidance and flow efficiency of the industrial waste gas airflow. A filter plate 17 is also installed between the installation pipe 2 and the connecting pipe 1 to intercept and filter the industrial waste gas, thereby achieving the function of ring plate purification. A fixing plate 13 is fixedly connected to the inner wall of the connecting pipe 1, and a rotating shaft 14 is rotatably connected to the fixing plate 13. A turbine blade 15 is installed at one end of the rotating shaft 14, and a scraper 16 is fixedly connected to the other end of the rotating shaft 14, with the scraper 16 in contact with the surface of the filter plate 17.

[0027] The flow of industrial waste gas in the connecting pipe 1 drives the turbine blades 15 to rotate, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 then drives the scraper 16 to rotate. During the rotation of the scraper 16, the filter plate 17 can be automatically cleaned, reducing the need for manual maintenance and improving the practicality and economy of the equipment.

[0028] To improve the mixing and reaction effect between industrial waste gas and spray, a baffle 7 is connected to the installation pipe 2 in a lifting manner. A nozzle 8 is installed on the baffle 7, and the spraying direction of the nozzle 8 is parallel to the plane of the baffle 7. A drive unit is also installed in the installation pipe 2 to drive the baffle 7 to move up and down. When the baffle 7 moves, the nozzle 8 sprays out a mist of liquid.

[0029] Reference Figure 3 Multiple sets of baffles 7 can be provided, but only two sets are provided in this device. The two sets of baffles 7 are staggered. On the one hand, they can block the airflow in the channel of the installation pipe 2, so that the baffles 7 can turbulent the industrial waste gas, thereby slowing down the waste gas flow rate and enhancing the mixing effect of the atomized liquid and the waste gas. On the other hand, they can also allow the waste gas to stay in the channel for a longer time, thereby increasing the contact time between the atomized water and the waste gas.

[0030] The aforementioned drive unit mainly includes a guide cylinder 3, which is fixedly connected to the outer wall of the mounting tube 2. A guide rod 4 is slidably connected to the guide cylinder 3, and a baffle 7 is fixedly connected to the bottom of the guide rod 4. The guide rod 4 extends into the guide cylinder 3 and is fixedly connected to a piston 5. The piston 5 is connected to the inner wall of the guide cylinder 3 through a return spring 6.

[0031] To drive the guide rod 4 to move up and down, a water pump 11 is fixedly connected to the outer wall of the mounting pipe 2. The output end of the water pump 11 is connected to the guide cylinder 3 through a pipe. The side wall of the guide cylinder 3 is fixedly connected to the nozzle 8 through a telescopic pipe 9. A one-way valve 10 is also provided on the telescopic pipe 9 to prevent the liquid in the pipe from flowing back. A liquid storage tank 12 is provided in the cavity of the connecting pipe 1. The input end of the water pump 11 is connected to the liquid storage tank 12 through a pipe.

[0032] The storage tank 12 is filled with a liquid medicine for purifying waste gas. The water pump 11 pressurizes the liquid medicine in the storage tank 12 and delivers it to the guide cylinder 3. During this process, the piston 5 is compressed by the pressurized liquid medicine and drives the guide rod 4 to move outward. This causes the guide rod 4 to move the baffle 7 downward, which turbulently turbulently affects the industrial waste gas. This slows down the flow rate of the waste gas and enhances the mixing effect between the atomized liquid and the waste gas. When the piston 5 moves to the side wall against the inner wall of the guide cylinder 3, the baffle 7 descends into the inlet hole of the telescopic tube 9, thus delivering the liquid medicine to the nozzle 8. The nozzle 8 is an atomizing nozzle, which allows the sprayed liquid medicine mist to be parallel to the plane of the baffle 7. This ensures that the liquid medicine mist fully purifies the waste gas, increases the mixing time between the liquid medicine mist sprayed by the atomizing nozzle 8 and the waste gas, and improves the mixing effect between the liquid medicine and the waste gas.

[0033] 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.
