Description

Technical Field

[0001] This utility model relates to the field of wet dust collector technology, and more specifically, it relates to a jet cleaning device for a wet dust collector. Background Technology

[0002] A wet scrubber, commonly known as a "demister," is a device that brings dust-laden gas into close contact with a liquid (usually water). It uses the inertial collision of water droplets and particles, or the thorough mixing of water and dust, as well as other effects, to capture particles, enlarge them, or retain them in a fixed container, thus achieving the effect of separating water and dust.

[0003] As the core component of a wet scrubber, the pulse-jet cleaning device has a crucial impact on the mixing effect of dust-laden gas and water mist, the dust capture efficiency, and the stable operation of the system. The performance of the pulse-jet cleaning device will significantly affect whether the wet scrubber can maintain stable and efficient operation under various complex working conditions, perform its dust removal function, ensure air quality, and maintain the normal operation of related equipment.

[0004] However, during the operation of wet scrubbers, the liquid sprayed by the pulse jet device inevitably accumulates excessively in certain parts of the equipment, leading to scaling. This scale not only occupies space and affects the normal operation of the equipment, but also undergoes electrochemical reactions with metal parts, thereby accelerating the corrosion process and significantly shortening the service life of the equipment. To address the scaling problem, it is necessary to clean the scale inside the equipment regularly, which undoubtedly increases the maintenance cost and operational complexity of the equipment. Therefore, a pulse jet device for wet scrubbers is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a jet cleaning device for a wet dust collector.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a jet-blowing device for a wet dust collector, comprising a wet dust collector tank, an atomizing device at the top of the wet dust collector tank, a main pipe inside the wet dust collector tank, one end of the main pipe penetrating the top of the wet dust collector tank and connected to the atomizing device, multiple sets of branch pipes evenly arranged on the side wall of the main pipe, and nozzles arranged on the branch pipes; telescopic cylinders symmetrically arranged at the top of the wet dust collector tank, a scraper ring arranged between the output ends of two telescopic cylinders, and the output end of the telescopic cylinder penetrating the top of the wet dust collector tank and connected to the scraper ring.

[0008] The present invention is further configured such that: the side wall of the wet dust collector is provided with an air inlet and an air outlet, the height of the air inlet is lower than the height of the air outlet, and the air inlet is tangent to the inner wall of the wet dust collector.

[0009] The present invention is further configured such that: the bottom of the wet dust collector is provided with a liquid outlet, the liquid outlet is funnel-shaped, and a check valve is provided on the side wall of the liquid outlet.

[0010] The present invention is further configured such that: a liquid inlet is provided at the top of the atomizing device, and the liquid inlet is used to connect to a liquid input pipe.

[0012] The present invention is further configured such that: the scraper ring is circular, and the outer wall of the scraper ring is in contact with the inner wall of the wet dust collector.

[0013] In summary, this application includes at least one of the following beneficial technical effects: by starting the telescopic cylinder and driving the output end to extend, the scraper ring moves smoothly down along the inner wall of the dust collector.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] Please see Figures 1-4 The present invention provides the following technical solution:

[0022] Example 1, see Figures 1-4 A jet cleaning device for a wet dust collector includes a wet dust collector tank 1, an atomizing device 2 installed on the top of the wet dust collector tank 1, a main pipe 3 installed inside the wet dust collector tank 1, one end of the main pipe 3 passing through the top of the wet dust collector tank 1 and connected to the atomizing device 2, and multiple sets of branch pipes 4 evenly arranged on the side wall of the main pipe 3, with nozzles 5 installed on the branch pipes 4.

[0023] The top of the wet dust collector 1 is symmetrically equipped with telescopic cylinders 8, and a scraper ring 9 is provided between the output ends of the two telescopic cylinders 8. The output ends of the telescopic cylinders 8 pass through the top of the wet dust collector 1 and are connected to the scraper ring 9.

[0024] The wet dust collector 1 is used to purify dust-laden gas. The atomizing device 2 is typically composed of key components such as a mixing chamber, nozzles, and pressure regulating devices, which work together to complete the atomization process. The atomizing device 2 can atomize water into fine particles, improving dust removal efficiency. The atomizing device 2 in this invention is a simplified diagram that does not affect the atomization process. The main pipe 3 inside the wet dust collector 1 runs through the top of the tank and is connected to the atomizing device 2 to achieve effective water mist delivery. Multiple sets of branch pipes 4 and nozzles 5 on the side wall of the main pipe 3 distribute water evenly inside the tank, ensuring uniform spraying of the entire dust collector, thereby improving the capture efficiency of particulate matter. In addition, the telescopic cylinders 8 symmetrically arranged on the top of the wet dust collector 1 can drive the scraper ring 9 to move up and down, scraping off liquid residue trapped on the tank wall and reducing scale formation.

[0025] When the dust removal operation is started, the liquid is atomized by the atomizing device 2 and turned into fine water mist. This water mist flows sequentially along the main pipe 3 to the branch pipe 4, and is then sprayed out through the nozzle 5, where it is fully mixed with the flue gas in the wet dust collector 1. During this process, the water mist combines with the dust in the flue gas, causing the dust to gradually settle, thereby achieving a highly efficient dust removal effect.

[0026] At the same time, the telescopic cylinder 8 on the top of the wet dust collector 1 is activated synchronously, and its output end extends at a constant speed, driving the scraper ring 9 to move smoothly down along the inner wall of the wet dust collector 1. During the movement, the scraper ring 9 can carry the liquid attached to the inner wall of the wet dust collector 1 down with it, effectively reducing the formation of scale, thereby reducing the risk of damage to the device caused by scale and ensuring the stable operation of the device.

[0027] See Figures 1-4 Furthermore, the wet dust collector 1 is symmetrically provided with support frames 11 on both sides, and the support frames 11 are used to support and fix the wet dust collector 1.

[0028] The support frame 11, through its symmetrical arrangement, not only ensures the stability of the wet dust collector 1, but also makes the equipment installation and maintenance more convenient.

[0029] See Figures 1-4 Furthermore, the side wall of the wet dust collector 1 is provided with an air inlet 6 and an air outlet 7. The height of the air inlet 6 is lower than the height of the air outlet 7, and the air inlet 6 is tangent to the inner wall of the wet dust collector 1.

[0030] The air inlet 6 is tangent to the inner wall of the wet dust collector 1, allowing the gas entering the collector to enter along the tangential direction of the collector. This tangential entry method causes the air to rotate, and this rotating flow can generate relative motion between the various parts inside the fluid, which helps to mix water mist and flue gas, thereby effectively improving the dust removal efficiency of the wet dust collector.

[0031] See Figures 1-4 Furthermore, the bottom of the wet dust collector 1 is provided with a liquid outlet 10, which is funnel-shaped, and a check valve 12 is provided on the side wall of the liquid outlet 10.

[0032] The outlet 10 is designed in a funnel shape, which can effectively guide and concentrate the discharge of liquid, prevent overflow and chaos, and improve the efficiency of waste liquid discharge. The check valve 12 can close or open the outlet 10 at any time to adapt to different working conditions and needs, thereby effectively managing the waste liquid in the tank, keeping the tank clean and dry, and improving the operational stability of the equipment.

[0033] See Figures 1-4 Furthermore, the top of the atomizing device 2 is provided with a liquid inlet 21, which is used to connect to a liquid input pipe.

[0034] When the liquid enters the device through the inlet 21, it is atomized by the internal atomizing element, turning the liquid into fine droplets, thereby increasing the contact area between the droplets and the flue gas.

[0035] See Figures 1-4 Furthermore, the multiple branch pipes 4 are arranged in a cross shape.

[0036] The cross-shaped design allows the medium to flow evenly from one direction to four different directions, thereby improving distribution efficiency and flexibility.

[0037] See Figures 1-4Furthermore, the scraper ring 9 is circular, and the outer wall of the scraper ring 9 is in contact with the inner wall of the wet dust collector 1.

[0038] The scraper ring 9 is designed in a circular shape and fits tightly against the inner wall of the wet dust collector 1. It can effectively scrape off the attached liquid on the inner wall and prevent the liquid from accumulating and forming scale.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
