Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a large-area cooling and slag-discharging drum water film dust collector. Background Art

[0002] In the process of chemical preparation, equipment such as boiling furnaces are used. Such equipment will discharge a large amount of high-temperature furnace gas during use. The furnace gas contains a large amount of slag ash. As the high-temperature furnace gas is discharged, the slag ash will run wild with the air flow and be discharged synchronously. If it is discharged directly, it will cause pollution to the environment. Therefore, dust removal treatment is required before discharge. The water film dust collector is a commonly used dust removal equipment in the chemical preparation process. It uses the adsorption and washing effect of the water film to effectively capture and remove dust particles in the gas.

[0003] However, it's worth noting that although the furnace gases undergo preliminary cooling before discharge through devices such as heat exchangers, the cooling effect of these devices is often limited, resulting in the furnace gases remaining at a relatively high temperature upon entering the water film dust collector. This high temperature directly affects the dust particle processing efficiency within the dust collector, making it difficult to effectively capture some fine dust particles, thereby reducing the overall dust removal effect. In light of this, we propose a water film dust collector with a large-area cooling slag discharge drum. Utility Model Content

A connecting shaft is coaxially connected between the two gears, and a motor for driving the connecting shaft to rotate is installed on the rear side of the box;

[0008] Hollow pipes are installed on both sides of the box body, and a water inlet is installed on the outer wall of the pipe body. Multiple branch pipes are also fixed on the outer wall of the pipe body. The branch pipes pass through the box body, and a second nozzle for spraying water to the cooling drum is installed at the end of the branch pipe.

[0009] Furthermore, a drainage pipe is installed below the rear side wall of the box body, and the drainage pipe is connected to the box body.

[0010] Furthermore, support plates are fixed on both the front and rear sides of the top of the box body, the front and rear ends of the connecting shaft are rotatably connected to the support plates through bearings, and the motor is fixedly connected to the rear support plate through bolts.

[0011] Furthermore, the cross-section of the air inlet bin is L-shaped, and the air inlet bin enters tangentially from the outer wall of the dust removal bin.

[0012] Furthermore, a sewage outlet is installed at the bottom end of the outer wall of the dust removal bin, and the sewage outlet is communicated with the dust removal bin.

[0015] Furthermore, the dust removal bin and the liquid pump are fixedly connected to the base via bolts, and the supporting legs are fixedly connected to the base via bolts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By setting up a dust removal bin and cooling components: on the one hand, the high-temperature dust-laden furnace gas enters the rotating cooling drum and flows in the spiral cooling flow channel. The heat of the furnace gas is absorbed by the cooling drum, and the multiple second nozzles on both sides spray cooling water onto the outer wall of the cooling drum for large-area heat dissipation, which can continuously cool the cooling drum, thereby achieving a cooling effect on the high-temperature dust-laden furnace gas. This design avoids the situation where the furnace gas enters the dust removal bin at a high temperature; on the other hand, the dust-laden furnace gas after cooling treatment enters the dust removal and rotates and rises, while the first nozzle sprays water and throws it to the drum wall. During the rising process of the dust-laden furnace gas, the dust particles are separated by centrifugal force and move around, and then are adsorbed by the water film layer flowing in the drum wall, thereby achieving dust removal treatment of the dust-laden furnace gas; this design can cool the dust-laden furnace gas before dust removal, avoiding the problem that some fine dust particles are difficult to be effectively captured due to the high temperature state of the dust-laden furnace gas, thereby ensuring the overall dust removal effect.

A connecting shaft 31 is coaxially keyed between the two gears 32, and a motor 33 for driving the connecting shaft 31 to rotate is installed on the rear side of the box body 30; a hollow tube body 36 is installed on the left and right sides of the box body 30, and a water inlet 360 is installed on the outer wall of the tube body 36. A plurality of branch pipes 37 are also fixed to the outer wall of the tube body 36, and the branch pipes 37 pass into the box body 30. A second nozzle 38 for spraying water to the cooling drum 34 is installed at the end of the branch pipe 37.

[0031] In this embodiment, a drain pipe 302 is installed below the rear side wall of the box body 30, and the drain pipe 302 is connected to the box body 30. The water source in the box body 30 is conveniently drained through the drain pipe 302.

[0032] In this embodiment, support plates 303 are fixed to the top and rear sides of the housing 30. The front and rear ends of the connecting shaft 31 are rotatably connected to the support plates 303 via bearings, and the motor 33 is fixedly connected to the rear support plate 303 via bolts. The support plates 303 provide support for the connecting shaft 31 and the motor 33.

[0033] In this embodiment, the air inlet bin 20 has an L-shaped cross-section and enters tangentially from the outer wall of the dust removal bin 2. This tangential entry design causes dust-laden furnace gas to rotate and rise after entering the air inlet bin 20, thereby facilitating the separation of dust particles due to centrifugal force during the ascent. The L-shaped design also prevents water from the dust removal bin 2 from entering the connection port 340 and the cooling drum 34.

[0034] In this embodiment, a sewage outlet 26 is installed at the bottom end of the outer wall of the dust removal bin 2, and the sewage outlet 26 is connected to the dust removal bin 2. The sewage outlet 26 is provided to facilitate the discharge of dust and other impurities in the dust removal bin 2.

[0035] In this embodiment, support legs 301 are installed at the four corners of the bottom of the box body 30, and the support legs 301 are fixedly connected to the box body 30 by bolts. The arrangement of the support legs 301 plays a role in stably supporting and fixing the box body 30.

[0036] In this embodiment, the second nozzles 38 are horizontal and face the cooling drum 34 , and the plurality of second nozzles 38 are linearly and evenly spaced. The arrangement of the plurality of second nozzles 38 increases the cooling effect on the cooling drum 34 .

[0037] In this embodiment, the dust removal bin 2 and the liquid pump 23 are fixedly connected to the base 1 by bolts, and the support legs 301 are fixedly connected to the base 1 by bolts. The bolt fixing method ensures the installation stability and reliability of the dust removal bin 2, the liquid pump 23 and the box body 30.

[0038] It can be understood that the water inlet 360 in this embodiment is connected to the water source. This design allows the water source to smoothly enter the tube body 36, thereby facilitating the cooling drum 34 to be cooled by spraying water through multiple second nozzles 38.

[0039] It should be added that, in this embodiment, a rubber sealing ring is installed at the connection port 340 passing through the box body 30. The setting of the sealing ring can prevent the water source in the box body 30 from leaking to the outside through the connection port 340, thereby avoiding unnecessary cleaning work.

[0040] It is worth noting that the motor 33 and the liquid pump 23 involved in this embodiment are existing conventional technologies and will not be described in detail here.

[0041] When in use, the user first turns on the power of the motor 33 and the liquid pump 23, and the motor 33 and the liquid pump 23 start to work. The output shaft of the motor 33 rotates to drive the connecting shaft 31 and the gear 32 to rotate. Because the gear 32 is engaged with the gear ring 39, the gear ring 39 drives the cooling drum 34 to rotate. At the same time, the water source enters the pipe body 36 and the multiple branch pipes 37 through the water inlet 360. The water source is sprayed on the cooling drum 34 through the multiple second nozzles 38 at the same time. At this time, the high-temperature dust-containing furnace gas enters the cooling drum 34 through the rear connection port 340 and is cooled. The high temperature of the high-temperature dust-laden furnace gas flows in the flow channel 341, and the high temperature of the high-temperature dust-laden furnace gas is absorbed by the cooling drum 34. The cooling water source cools down the cooling drum 34, and the high-temperature dust-laden furnace gas is cooled down. Then, the cooled dust-laden furnace gas enters the dust removal bin 2 through the connecting pipe 21 and the air inlet bin 20. The first nozzle 25 sprays the water source at the same time. The water source flows along the inner wall of the dust removal bin 2 and forms a water film. During the rising process of the dust-laden furnace gas, the dust particles are separated by the centrifugal force and move around, and then are adsorbed by the flowing water film layer. Finally, the dust-removed furnace gas is discharged through the exhaust bin 22.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention.
