Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to an unpowered dual-fluid dry mist dust suppression device. Background Art

[0002] Dry fog refers to water mist particles larger than 2.5 microns and smaller than 10 microns. It is a type of fog that does not leave exposed surfaces wet after falling. Dry fog dust suppression technology captures dust through a "clouded" dry fog. The dry fog main unit filters the air and water, then controls the opening and closing of a solenoid valve according to a set pressure and flow rate according to a switching program. The mist is then piped into the sprayer assembly. The multiple dry fog nozzles in the sprayer assembly then spray dry fog, which combines with dust particles in the air to form agglomerates of dust and dry fog. These agglomerates settle due to gravity, suppressing dust at the source and preventing moisture on the material surface. This advanced technology is superior to traditional spray dust removal, and is therefore widely used in dusty places such as mines, power plants, ports, and waste disposal stations.

[0003] The dry mist nozzles of the dry mist dust suppression devices commonly used on the market can only be fixed at one angle for spraying. The spraying area of each dry mist nozzle is limited, and the overall spraying area of the dry mist dust suppression device is not high. If more dry mist nozzles are added to increase the spraying area, it will not only be more costly, but will also cause the air pressure and water pressure in the dry mist host to decrease, resulting in poor spraying effect; if more dry mist nozzles are not added, the spraying area will be lower, resulting in reduced dust suppression efficiency of the dry mist. Utility Model Content

[0004] In order to solve the technical problems in the prior art that the dry mist nozzle can only be fixed at one angle for spraying, the spraying area of each dry mist nozzle is limited, and the overall spraying area of the dry mist dust suppression device is not high, the utility model provides the following technical solutions.

[0005] The utility model discloses an unpowered dual-fluid dry mist dust suppression device, comprising a dry mist main unit connected to an air compressor and a clean water pipe, the dry mist main unit being connected to a water outlet pipe provided with a plurality of water distribution pipes and an air outlet pipe provided with a plurality of air distribution pipes, the water distribution pipes and the air distribution pipes being connected to a sprayer assembly provided with a plurality of mist outlet pipes, the sprayer assembly being connected to a plurality of spray assemblies, the spray assembly comprising a dynamic sealing sleeve rotatably connected to the mist outlet pipe and a transfer pipe fixedly connected to the dynamic sealing sleeve, the transfer pipe being fixedly connected to a dry mist nozzle at one end away from the dynamic sealing sleeve, a spiral groove being provided inside the transfer pipe and communicating with the mist outlet pipe and the dry mist nozzle, and a plurality of spray holes distributed along the axial direction of the dry mist nozzle at the end of the dry mist nozzle.

[0006] As a further technical solution, a sealing cavity is provided on a side of the transfer tube close to the mist outlet pipe, and a sealing ring is provided in the sealing cavity.

[0007] As a further technical solution, the spiral groove is a groove located on the inner wall of the transfer tube, and the water mist from the mist outlet pipe passes axially from the transfer tube and through the spiral groove.

[0009] As a further technical solution, the dry mist main unit is connected to an air intake pipe provided with a pressure gauge, and the air intake pipe is connected to an air storage tank through a spare pipe.

[0010] As a further technical solution, the dry mist main unit is connected to a water inlet pipe, and the water inlet pipe is connected to a filter connected to the clean water pipe.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 and Figure 2 As shown, the present invention provides a non-powered dual-fluid dry mist dust suppression device, comprising a dry mist main unit 3 connected to an air compressor 1 and a clean water pipe 2. The dry mist main unit 3 is connected to a sprayer assembly 4. The air compressor 1 provides an air source that meets pressure requirements and standards for the dry mist main unit 3, while the clean water pipe provides water for the dry mist main unit 3. The dry mist main unit 3 controls the opening and closing of a solenoid valve at a set pressure and flow rate according to a switching program. The air and water are then delivered to the sprayer assembly 4 via a water outlet pipe 301 and an air outlet pipe 302, achieving spray dust suppression. The dry mist main unit 3 comprises an electronic control system, a multifunctional control system, and a flow control system. It utilizes existing technologies, and its detailed structure is not further described.

[0021] The spray box assembly 4 is used to receive the air and water sent in sequence by the dry fog host 3 and convert them into dry mist with a particle diameter of 2 to 10 μm and spray it out. It is sprayed towards the dust suppression point according to the control instructions of the dry fog dust suppression host. When the dry mist and dust particles contact and collide with each other, the dust particles stick to each other, condense and become larger, and settle under the action of their own gravity, thereby achieving the effect of dust suppression.

[0022] In a preferred embodiment, the dry mist main unit 3 is connected to an air intake pipe 14 equipped with a pressure gauge 9, which is connected to an air storage tank 10 via a backup pipe 11. The pressure gauge 9 is used to monitor the air pressure in the air intake pipe 14 and the dry mist main unit 3. When insufficient pressure is detected, the valve of the air storage tank 10 is immediately opened to allow high-pressure air to enter the air intake pipe 14 and the dry mist main unit 3. This maintains the pressure provided to the dry mist main unit 3, prevents large pressure fluctuations in the dry mist main unit 3, balances the pressure, and reduces the frequent starting and stopping of the air compressor 1.

[0023] The dry mist host 3 is connected to a water inlet pipe 13, and the water inlet pipe 13 is connected to a filter 12 connected to the clean water pipe 2. The filter 12 can filter impurities in the water in the clean water pipe 2 to prevent blockage in the dry mist host 3 and the sprayer assembly 4 after long-term operation.

[0024] like Figure 3 and Figure 4 As shown, in a preferred embodiment, the dry mist main unit 3 is connected to a water outlet pipe 301 and an air outlet pipe 302. The water outlet pipe 301 is provided with multiple water distribution pipes 303, each of which is equipped with an independent valve. The air outlet pipe 302 is provided with multiple air distribution pipes 304, each of which is also equipped with an independent valve. Each water distribution pipe 303 and each air distribution pipe 304 is connected to a sprayer assembly 4. The side of the sprayer assembly 4 facing the material is provided with multiple mist outlet pipes 401. The dry mist generated by the sprayer assembly 4 is sprayed out through the mist outlet pipes 401.

[0025] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the sprayer assembly 4 is connected to a plurality of spray assemblies 5, and the spray assembly 5 includes a dynamic sealing sleeve 6 rotatably connected to the mist outlet pipe 401, the dynamic sealing sleeve 6 is fixedly connected to a transfer tube 7, and the end of the transfer tube 7 away from the dynamic sealing sleeve 6 is fixedly connected to a dry mist nozzle 8. When the dry mist flows from the mist outlet pipe 401 to the transfer tube 7, the transfer tube 7 can be driven to rotate relative to the mist outlet pipe 401 without additional power.

[0026] Specifically, a sealed cavity 702 is provided on the side of the adapter tube 7 near the mist outlet pipe 401. A sealing ring is located within the sealed cavity 702, further enhancing the seal between the mist outlet pipe 401 and the adapter tube 7. A spiral groove 701 is provided within the adapter tube 7, located on one side of the sealed cavity 702, connecting the mist outlet pipe 401 and the dry mist nozzle 8. The end of the dry mist nozzle 8 is provided with a plurality of spray holes 801 distributed axially along the dry mist nozzle 8. The multiple spray holes 801 have different orientations. When the pressurized dry mist ejected from the mist outlet rod 401 passes through the spiral groove 701, it drives the adapter tube 7 to rotate relative to the mist outlet pipe 401. Consequently, the dry mist nozzle 8 rotates with the adapter tube 7. The multiple axially distributed spray holes 801 can spray in multiple directions, increasing the spray area of a single dry mist nozzle 8. Consequently, the spray area of the entire sprayer assembly 4 is increased without adding more dry mist nozzles 801.

[0027] The spiral groove 701 can have two different structures. In a preferred embodiment, Figure 5 As shown, the spiral groove 701 is a spiral groove located on the inner wall of the adapter tube 7. At the same time, the inner cavity of the adapter tube 7 can also pass through the dry mist axially. At this time, the water mist from the mist outlet pipe 401 passes through the adapter tube 7 axially and the spiral groove 701 at the same time. When the pressurized dry mist passes through the spiral groove 701, it can drive the adapter tube 7 to rotate relative to the mist outlet pipe 401, and then the dry mist nozzle 8 rotates with the adapter tube 7. With this structure, the rotation speed of the adapter tube 7 is relatively slow.

[0028] In another preferred embodiment, the adapter tube 7 is not provided with an inner cavity for the dry mist to pass through in the axial direction. There is only a spiral groove 701 (not shown) in the adapter tube 7. The two ends of the spiral groove 701 are respectively connected to the mist outlet pipe 401 and the dry mist nozzle 8. The water mist of the mist outlet pipe 401 passes only through the spiral groove 701. When the pressurized dry mist passes through the spiral groove 701, it can drive the adapter tube 7 to rotate relative to the mist outlet pipe 401, and then the dry mist nozzle 8 rotates with the adapter tube 7. With this structure, the adapter tube 7 rotates faster.

[0029] The preferred specific implementation methods and embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above implementation methods and embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes or equivalent substitutions can be made without departing from the concept of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments that fall within the scope of the claims of this application belong to the scope of protection of the present invention.
