Description

Technical Field

[0001] The present invention relates to the technical field of chemical dust removal, in particular to a dust removal device for safe chemical production. Background Art

[0002] With the development of industrialization, large amounts of dust and particulate matter are emitted into the atmosphere, polluting the environment and posing a serious threat to human health. To address this issue, dust removal technologies have emerged to reduce dust emissions from industrial production processes, improve air quality, and protect the ecological environment and human health. Wet dust removal, among other technologies, utilizes water or other liquids in contact with dust to capture and separate it from the airstream. Wet dust removal offers high dust removal efficiency, eliminates fire and explosion risks, and is suitable for handling hot or sticky dust.

[0003] Chinese patent CN116712814B announced on November 3, 2023 discloses a chemical production organic waste gas recovery and treatment device. By setting a dust scraping part, the dust scraping part can scrape off the dust adsorbed on the filter plate, so that the filter plate can be used continuously for a long time, reducing the number of times the filter plate is shut down for maintenance and replacement. At the same time, by setting a movable defoaming rod, the driving part will drive the sleeve to rotate, thereby driving the movable defoaming rod to move to eliminate bubbles on the liquid surface of the dissolved liquid, reducing the number of shutdowns for maintenance of the hydrolysis box, so that the chemical production organic waste gas recovery and treatment device can continue to operate for a long time, thereby improving the efficiency of waste gas treatment work. However, in this chemical production organic waste gas recovery and treatment device, some tiny dust will be captured by the liquid inside the hydrolysis box after entering the hydrolysis box. After long-term use, the dust entering the hydrolysis box will become more and more, and a layer of floating matter will form on the surface of the liquid. In order not to affect the normal operation of the device, it is necessary to shut down regularly for cleaning. Summary of the Invention

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0029] See also Figures 1-12The present invention provides a technical solution: a dust removal device for chemical production safety, comprising a dust removal box 1, a discharge pipe 2 is installed on the outer wall of the bottom end of the dust removal box 1, an electric valve 3 is installed on the outer wall of the discharge pipe 2, the interior of the dust removal box 1 is divided into a hydrolysis bin and a filtration bin by a partition 4, and the interior of the hydrolysis bin contains a liquid for water flow filtering of dust in the air, a separation component for separating dust from liquid is provided on the inner wall of the dust removal box 1, the separation component comprises a connecting sleeve 5 and a spray mechanism installed on the inner wall of the dust removal box 1, the spray mechanism comprises a watering pipe 20 installed on the inner wall of the hydrolysis bin, the outer edge of the watering pipe 20 is provided with nozzles 21 distributed at equal intervals along the circumferential direction, the connecting sleeve 5 is provided with a crushing mechanism for crushing the gas, and the crushing mechanism is installed on the outer wall of the connecting sleeve 5 in a rotating manner along the circumferential direction of the connecting sleeve 5. The crushing mechanism includes a second grid stirring blade 11 provided on the outer wall of the connecting sleeve 5, and a rotating sleeve 6 is rotatably connected to the outer wall of the top end of the connecting sleeve 5. A connecting shaft 7 is fixedly connected to the outer wall of the top end of the rotating sleeve 6. A motor 8 adapted to the connecting shaft 7 is provided on the outer wall of the dust removal box 1, and a water inlet 24 is provided on the inner wall of the top end of the rotating sleeve 6. A reciprocating screw 33 adapted to the rotating sleeve 6 is provided on the inner wall of the connecting sleeve 5, and a piston 34 adapted to the connecting sleeve 5 is provided on the outer wall of the reciprocating screw 33.

[0030] During use, the preliminarily filtered air is injected into the interior of the hydrolysis chamber through the pipeline, and bubbles are formed in the liquid inside the hydrolysis chamber. At this time, the external power supply is connected to start the motor 8 to drive the crushing mechanism to work through the connecting shaft 7 and the rotating sleeve 6, thereby crushing the bubbles in the liquid and breaking them into countless tiny bubbles, thereby promoting the contact between air and liquid and improving the separation efficiency of the liquid from dust in the air. When the small bubbles rise to the surface of the liquid, water mist is sprayed onto the surface of the liquid through the spray mechanism. When the water mist particles hit the foam surface at a certain speed, they will produce a mechanical force on the foam, destroy the liquid film balance of the foam, and cause the bubbles to burst, which can promote the contact between air and liquid again. At the same time, the sprayed liquid will fully contact and mix with the air overflowing from the inside of the liquid, and the overflowing dust will be The tiny dust is captured and falls downward into the liquid surface under the action of force and floats on the liquid surface. As the liquid inside the filtration bin enters the hydrolysis bin through the spray mechanism, the liquid level inside the hydrolysis bin rises, so that the dust on the liquid surface enters the rotating sleeve 6 together with the liquid through the water inlet 24. When the reciprocating screw 33 drives the piston 34 to rise to the top of the connecting sleeve 5, the liquid and dust inside the rotating sleeve 6 will enter the space below the piston 34 inside the connecting sleeve 5. Then, the piston 34 moves downward to press the liquid, squeeze the liquid into the interior of the filtration bin, and squeeze the dust. Through the squeezing of the piston 34, the dust is squeezed into blocks and enters the interior of the discharge pipe 2. Then, the electric valve 3 is started to discharge the dust.

[0031] In order to prevent some dust from floating toward the air outlet with the air after spraying water mist into the hydrolysis chamber, please refer to Figure 5 and Figure 6 A V-shaped busbar 22 is fixedly connected to the top outer wall of the dust removal box 1. The V-shaped busbar 22 includes a busbar body 2201. A V-shaped busbar groove 2202 is provided on the top outer wall of the busbar body 2201. Multiple groups of leakage holes 2203 are provided on the outer wall of the V-shaped busbar groove 2202. Multiple groups of busbars 23 are provided on the bottom outer wall of the busbar body 2201.

[0032] During use, when dust and small water droplets float upward with the air, the busbar body 2201 can intercept the small water droplets and dust in the air, so that the dust adheres to the surface of the busbar body 2201 and the busbar 23 through the small water droplets. Through the V-shaped design of the busbar body 2201 and the busbar 23, the small water droplets mixed with dust can slide downward along the surface of the busbar body 2201 and the busbar 23. In this process, multiple small water droplets will gather together into water droplets and fall to the surface of the liquid, and the small water droplets entering the V-shaped busbar groove 2202 will also gather together and drip onto the surface of the liquid through the leakage hole 2203.

[0033] See also Figure 7 、 Figure 8 and Figure 9 The separation component also includes a baffle 25 arranged on the inner wall of the rotating sleeve 6 and adapted to the water inlet 24, and a connecting rod 30 slidably connected to the piston 34. The inner wall of the rotating sleeve 6 is provided with a damping rod 26 adapted to the baffle 25, and a sealing ring 27 is fixedly connected to the outer wall of one end of the damping rod 26. The sealing ring 27 includes a sealing ring body 2701, a guide surface 2702 is provided on the top outer wall of the sealing ring body 2701, and a fitting surface 2703 adapted to the conical block 28 is provided on the outer wall of the sealing ring body 2701. The inner wall of the bottom end of the rotating sleeve 6 is provided with a conical block 28 adapted to the sealing ring 27, and the outer wall of the bottom end of the damping rod 26 is provided with a connecting rod 30 adapted to Connecting ring 29, a first limit plate 31 is fixedly connected to the outer wall of the top end of the connecting rod 30, a second limit plate 32 is fixedly connected to the outer wall of the bottom end of the connecting rod 30, a filter sponge 35 is bonded to the outer wall of the bottom end of the piston 34, a conical groove 36 is provided on the outer wall of the top end of the piston 34, a discharge hole 37 is provided on the outer wall of the piston 34 at the bottom end of the conical groove 36, a connecting column 38 is slidably connected to the inner wall of the piston 34, a connecting spring 39 adapted to the connecting column 38 is provided on the inner wall of the piston 34, a limit block 40 adapted to the discharge hole 37 is provided on the outer wall of one end of the connecting column 38, and a push rod 43 adapted to the limit block 40 is provided on the inner wall of the connecting sleeve 5.

[0034] When in use, as the liquid level inside the hydrolysis chamber rises, the dust on the surface of the liquid enters the interior of the rotating sleeve 6 along with the liquid through the water inlet 24. At the same time, the rotating sleeve 6 can drive the reciprocating screw 33 to rotate synchronously. Through the rotation of the reciprocating screw 33, the rotational motion of the reciprocating screw 33 and the piston 34 can be converted into a linear motion of the piston 34 inside the rotating sleeve 6. When the piston 34 slides upward inside the rotating sleeve 6 until it contacts the first limit plate 31, the piston 34 continues to move upward. When the piston 34 moves upward, it pushes the connecting rod 30 upward through the first limiting plate 31, thereby lifting the connecting ring 29 and the damping rod 26. When the damping rod 26 slides upward, it can push the sealing ring body 2701 to move upward synchronously, so that the fitting surface 2703 is separated from the conical block 28. At the same time, the damping rod 26 will push the baffle 25 upward and limit the water inlet 24, so that the liquid and dust inside the rotating sleeve 6 enter the interior of the connecting sleeve 5. At the same time, as the piston 34 rises, the top The rod 43 pushes the limit block 40 down and releases the limit on the discharge hole 37, so that the limit block 40 pulls the connecting column 38 to slide downward and squeeze the connecting spring 39. At this time, the liquid and dust entering the interior of the rotating sleeve 6 will gather on the surface of the discharge hole 37 through the tapered groove 36 and enter the position below the piston 34 through the discharge hole 37. Then, the piston 34 is pushed downward by the rotation of the reciprocating screw 33. At this time, the connecting spring 39 is pulled back by the force to make the limit block 40 reset, so that the piston 34 squeezes Liquid and dust. During this process, the liquid will be squeezed into the interior of the filter bin, and the dust will be trapped inside the connecting sleeve 5. When the piston 34 moves downward and contacts the second limit plate 32, the piston 34 continues to move downward, causing the piston 34 to press the second limit plate 32, thereby pulling the connecting rod 30 downward, thereby driving the sealing ring 27 and the conical block 28 to close, and pulling the baffle 25 to release the limit on the water inlet 24, allowing dust and liquid to enter the interior of the rotating sleeve 6 again.

[0035] See also Figure 10 and Figure 11 The separation component also includes a slider 41 mounted on the outer wall of the piston 34, and a limit plate 47 rotatably connected to the inner wall of the dust removal box 1. A slide groove 42 adapted to the slider 41 is provided on the inner wall of the connecting sleeve 5, and a screw rod 44 is rotatably connected on the inner wall of the slide groove 42. A transmission gear 45 adapted to the screw rod 44 is provided on the inner wall of the dust removal box 1, and a return spring 46 adapted to the screw rod 44 is provided on the inner wall of the dust removal box 1. A protrusion 48 adapted to the transmission gear 45 is provided on the outer wall of the limit plate 47. The limit plate 47 includes a limit plate body 4701, an opening 4702 is provided on the outer wall of the limit plate body 4701, and a scraping surface 4703 adapted to the filter sponge 35 is provided on the inner wall of one end of the opening 4702, and a discharge port 49 adapted to the opening 4702 is provided on the inner wall of the bottom end of the dust removal box 1.

[0036] When in use, when the piston 34 descends, it can drive the slider 41 to slide inside the slide groove 42. When the piston 34 slides downward to a certain position, the slider 41 will push the screw rod 44 to move downward and squeeze the return spring 46. Through the threaded connection between the screw rod 44 and the transmission gear 45, the screw rod 44 can drive the transmission gear 45 to rotate when it moves downward. Through the engagement of the transmission gear 45 with the protrusion 48, the transmission gear 45 can drive the limit plate 47 to rotate synchronously through the protrusion 48 when rotating. When the limit plate 47 rotates, it can release the restriction on the discharge port 49. At the same time, the scraping surface 4703 can scrape the dust on the surface of the filter sponge 35 into the inside of the opening 4702, and cooperate with the rotation of the limit plate body 4701 to transport the dust to the inside of the discharge port 49. When the piston 34 rises, the force of the return spring 46 pushes the screw rod 44 to return to its original position, and drives the limit plate 47 to rotate through the transmission gear 45, so that the limit plate 47 limits the discharge port 49 again.

[0037] See also Figure 12 The separation component also includes a water outlet 50 arranged on the inner wall of the bottom end of the dust removal box 1, directly below the connecting sleeve 5. A filter screen 51 is installed on the inner wall of the water outlet 50 at one end close to the connecting sleeve 5, and a conical rubber sleeve 52 is installed on the inner wall of the water outlet 50. The end of the conical rubber sleeve 52 away from the connecting sleeve 5 is a bell mouth 53. A fixing block 54 adapted to the water outlet 50 is provided on the outer wall of the top end of the bell mouth 53, and an arc-shaped spring piece 55 adapted to the bell mouth 53 is provided on the outer wall of the fixing block 54, and the arc-shaped spring piece 55 is connected to the outer wall of the bottom end of the bell mouth 53.

[0038] During use, when the piston 34 squeezes the liquid and dust inside the connecting sleeve 5, the liquid will pass through the filtration of the filter screen 51 and enter the inside of the water outlet 50. Then, the liquid will exert pressure on the bottom surface of the conical rubber sleeve 52, causing the arc-shaped spring sheet 55 to deform under the action of the force, thereby causing the bell mouth 53 to deform, thereby releasing the conical rubber sleeve 52 from limiting the water outlet 50. At this time, the liquid can pass through the water outlet 50 and enter the inside of the filter bin. When the piston 34 moves upward, the liquid inside the filter bin will enter the inside of the conical rubber sleeve 52 through the bell mouth 53, thereby applying a tension to the conical rubber sleeve 52, and the force generated by the arc-shaped spring sheet 55 can push the bell mouth 53 of the conical rubber sleeve 52 to fully open, thereby limiting the water outlet 50.

[0039] See also Figure 5The spray mechanism includes a water pump 18 installed on the outer wall of the top of the dust removal box 1, and a sprinkler pipe 20 arranged on the inner wall of the top of the dust removal box 1. A water suction pipe 17 adapted to the filter bin is provided on the outer wall of one end of the water pump 18, and a water injection pipe 19 adapted to the sprinkler pipe 20 is provided on the outer wall of one end of the water pump 18. Multiple groups of nozzles 21 are provided on the outer wall of the sprinkler pipe 20.

[0040] During use, connect an external power source to start the water pump 18 to extract the liquid inside the filter bin through the water extraction pipe 17, and inject it into the sprinkler pipe 20 through the water injection pipe 19, so that the water pressure inside the sprinkler pipe 20 increases, and then spray water mist to the hydrolysis bin through the nozzle 21. By spraying water mist to the hydrolysis bin, the bubbles on the liquid surface can be broken, and the dust in the air can be captured and its weight increased, so that the dust falls into the liquid surface.

[0041] See also Figure 3 The crushing mechanism includes a first mesh stirring blade 9 installed on the outer wall of the rotating sleeve 6, and a connecting sleeve 10 provided on the outer wall of the connection sleeve 5 and the rotating sleeve 6. The second mesh stirring blade 11 is fixedly connected to the outer wall of the connecting sleeve 10, and an outer gear ring 12 is fixedly connected to the outer wall of the bottom end of the rotating sleeve 6. A connecting gear 13 adapted to the outer gear ring 12 is provided on the outer wall of the top end of the connecting sleeve 5, and an inner gear ring 14 adapted to the connecting gear 13 is provided on the inner wall of the connecting sleeve 10.

[0042] During use, when the rotating sleeve 6 rotates, it can drive the first grid stirring blade 9 and the outer ring gear 12 to rotate synchronously. Through the mutual engagement of the outer ring gear 12, the connecting gear 13 and the inner ring gear 14, the rotating sleeve 6 can drive the connecting sleeve 10 and the second grid stirring blade 11 to rotate in the opposite direction of the first grid stirring blade 9. Through the rotation of the first grid stirring blade 9 and the second grid stirring blade 11, the grids on the surfaces of the first grid stirring blade 9 and the second grid stirring blade 11 cut and break the bubbles in the liquid, thereby promoting the contact between air and liquid and improving the separation efficiency of the liquid from dust in the air.

[0043] See also Figure 4 A plurality of first guide plates 15 are arranged at equal intervals on the inner wall of the dust removal box 1, and there is a gap between the inner periphery of the first guide plates 15 and the outer wall of the rotating sleeve 6. A plurality of second guide plates 16 are arranged at equal intervals on the outer wall of the rotating sleeve 6, and there is a gap between the outer edge of the second guide plates 16 and the inner wall of the dust removal box 1, and cooperate with the first guide plates 15 to form a guide channel.

[0044] During use, the gas enters the hydrolysis chamber and reacts with the liquid to form bubbles, which will rise. When the bubbles rise to the point where they come into contact with the bottom surface of the first guide plate 15, the bottom ends of the first guide plate 15 and the second guide plate 16 are inclined, so that the bubbles can move along the bottom inclined surface of the first guide plate 15 toward the gap between the first guide plate 15 and the outer wall of the rotating sleeve 6, and enter the channel between the first guide plate 15 and the second guide plate 16 through the gap, and then along the bottom inclined surface of the second guide plate 16 toward the gap between the second guide plate 16 and the inner wall of the dust removal box 1. The dust moves and makes the bubbles rise to the upper surface of the second guide plate 16 through the gap. After the bubbles are broken by the water mist, the dust floats on the surface of the liquid. When the floating dust flows into the interior of the rotating sleeve 6 through the water inlet 24 together with the liquid, the liquid below can only rise to the surface through the gap between the outer edge of the second guide plate 16 and the inner wall of the dust removal box 1. The dust floating on the surface of the liquid will flow along the surface of the uppermost second guide plate 16 to the surface of the water inlet 24, and finally flow into the interior of the rotating sleeve 6 through the water inlet 24.
