Description

Technical Field

[0001] This invention relates to the technical field of air pollution control, and in particular to a heavy VOCs exhaust gas colloidal removal device that uses oil-based washing. Background Technology

[0002] During crude oil refining, oil refineries produce large quantities of byproducts, including asphalt, residual oil, heavy waste oil, wax oil, and heavy fuel oil. Fine chemical and coal chemical industries also generate byproducts such as sludge, oil slurry, and heavy waste oil, in enormous quantities, amounting to tens of thousands of tons annually, transported and stored at factories, tank farms, docks, and stations. All of these oil products contain gum-like substances. To meet transportation and storage requirements, these heavy oils are stored and transported at temperatures ranging from 50 to 190°C, resulting in high-temperature VOCs exhaust gases that produce a strong odor and severely pollute the environment, impacting human health. Furthermore, the high temperature and gum-like substances in these exhaust gases directly hinder the treatment of this type of atmospheric pollution. VOCs exhaust gases from asphalt, residual oil, sludge, oil slurry, heavy waste oil, wax oil, and heavy oil from chemical plants all contain sticky, colloidal polymers that adhere to the inner walls of pipes and equipment, affecting heat transfer, output, and normal system operation. These cannot be separated or removed using conventional filtration equipment. Existing technologies generally use conventional filters, which are prone to clogging and require frequent replacement of filter components and manual removal of the polymers. A significant number of similar exhaust gases remain untreated. Therefore, this paper proposes a heavy VOCs exhaust gas polymer removal device using oil-based scrubbing to address these problems.

[0035] Example 1

[0036] Reference Figures 1-11This invention provides a heavy VOCs exhaust gas colloid removal device using oil-medium washing. The device includes an external component 100, an adjustment component 200, and a filter component 300. The external component 100 includes a treatment tank 101, an exhaust tank 102 connected to the treatment tank 101, a cooling water system 103 connected to both the treatment tank 101 and the exhaust tank 102, a circulation pump 104, and a cooling filter 105. The adjustment component 200, mounted on the treatment tank 101, includes a mounting frame 201, a motor 202 mounted on the mounting frame 201, and a rotating rod 2 connected to the motor 202. 03. An adjusting block 204 disposed on the rotating rod 203, a crossbar 205 and an adjusting rod 206 disposed on the mounting frame 201, a starting rod 207 that fits against the adjusting block 204, a slider 208 connected to the starting rod 207, and a spraying hoop 209 disposed on the slider 208; and a filter assembly 300 disposed in the treatment tank 101, including an arc frame 301, a fan blade 302 disposed on the arc frame 301, a limiting rod 303 disposed on the fan blade 302, a sliding plate 304 slidably connected to the arc frame 301, and a cylinder 305 connected to the sliding plate 304.

[0037] The treatment tank 101 has an air inlet 1011 at the top, a screen 1012 at the bottom, a liquid outlet 1013 at the bottom, and a jacket 1014 on its upper part. The treatment tank 101 is connected to an outlet tank 102, and a valve is provided between them. Cooling water 103 is connected to both the treatment tank 101 and the outlet tank 102, and a cooling filter 105 is installed on the cooling water 103 pipeline. A circulation pump 104 forms a loop with the treatment tank 101 and the outlet tank 102. The exhaust gas enters the treatment tank 101 through the air inlet 1011 at the top of the treatment tank 101, and is then transferred from the treatment tank 101 to the exhaust tank 102. The cooling filter 105 is installed on the cooling water 103 pipeline, which can effectively filter impurities in the cooling water 103 and protect the stable operation of the system. The cooling water 103 circulates between the treatment tank 101 and the exhaust tank 102 through the circulation pump 104 to cool the exhaust gas and directly wash off the colloid.

[0038] To control the spray direction of the washing liquid, the mounting bracket 201 is fixedly mounted on the side wall of the treatment tank 101. The motor 202 is fixedly mounted on the mounting bracket 201, and the output shaft of the motor 202 is fixedly connected to the rotating rod 203. The rotating rod 203 is rotatably mounted on the mounting bracket 201, and a protrusion 2031 is provided on the side wall of the rotating rod 203. The adjusting block 204 is provided with multiple discs of different radii. The adjusting block 204 is sleeved on the rotating rod 203, and a groove 2041 is provided on the inner wall of the adjusting block 204. The protrusion 2031 is embedded in the groove 2041. An annular groove 2042 is provided on the adjusting block 204. A crossbar 205 is provided above the rotating rod 203, and several positioning grooves 2051 are provided on the crossbar 205. The adjusting rod 206 is slidably mounted on the crossbar 205. The bottom of the adjusting rod 206 is provided with jaws 2061, which are embedded in the annular groove 2042. The adjusting rod 206 is provided with a handle 2062. The adjusting rod 206 is also provided with a buckle 2063 and a return spring 2064. The buckle 2063 is slidably mounted in the adjusting rod 206 and can be embedded in the positioning groove 2051. The return spring 2064 is located between the buckle 2063 and the inner wall of the adjusting rod 206. The starting rod 207 is rotatably mounted on the mounting frame 201. One end of the starting rod 207 is provided with a roller 2071, which is in contact with the adjusting block 204. The other end of the starting rod 207 is rotatably connected to a connecting rod 2072, which is also rotatably connected to a slider 208. A spring 2073 is provided at the bottom of the starting rod 207. The slider 208 is slidably mounted on the mounting frame 201. The spray hoop 209 is fixedly connected to the slider 208 and is slidably mounted in the interlayer 1014. Multiple nozzles 2091 are provided on the inner wall of the spray hoop 209. The nozzles 2091 are connected to a washing liquid, which is an oil product.

[0039] Exhaust gas enters the treatment tank 101 through the air inlet 1011. The movement frequency of the spray clamp 209 can be adjusted according to the exhaust gas velocity to ensure complete mixing of the washing liquid with the exhaust gas. When it is necessary to change the movement of the spray clamp 209, the motor 202 is started. The output shaft of the motor 202 drives the rotating rod 203 to rotate on the mounting bracket 201. Since the rotating rod 203 has a protrusion 2031 that is embedded in the groove 2041 of the adjusting block 204 outside the rotating rod 203, the rotating rod 203 can drive the adjusting block 204 to rotate synchronously. A roller 2071 is provided outside the adjusting block 204 and fits against the outer wall of the adjusting block 204. The adjusting block 204 and the rotating rod 203 are not concentrically arranged, therefore the adjustment... The discs of different radii on block 204 can push roller 2071. Since roller 2071 is mounted on starting rod 207, and starting rod 207 is rotatably mounted on mounting bracket 201, starting rod 207 is generally right-angled. Starting rod 207 is driven by adjusting block 204 to start cyclic swinging. At the other end of adjusting block 204, it moves up and down synchronously and drives slider 208 to slide up and down in mounting bracket 201 through connecting rod 2072. It is easy to see that the movement amplitude and speed of slider 208 are affected by the swing of starting rod 207, and the swing of starting rod 207 is the result of the rotation of adjusting block 204. Spring 2073 is also provided at the bottom of starting rod 207. Spring 2073 can ensure that the roller 207 at the end of starting rod 207 is stable. 1. Maintain contact with the adjusting block 204; To change the swing amplitude of the starting lever 207, simply adjust the disc that contacts the roller 2071, grasp the handle 2062 on the adjusting lever 206, and manually move the adjusting lever 206 on the crossbar 205. The jaws 2061 at the bottom of the adjusting lever 206 are embedded in the annular groove 2042 of the adjusting block 204. The movement of the adjusting lever 206 can drive the adjusting block 204 to move synchronously on the rotating rod 203. The buckle 2063 and the return spring 2064 are set in the adjusting lever 206 so that the buckle 2063 can be pushed into the positioning groove 2051 by the return spring 2064 each time it passes through the positioning groove 2051, achieving the positioning effect, so that the roller 2071 is always in contact with a certain position. The diameter of the disc corresponds to the diameter of the roller 2071, which can be adjusted to fit the disc diameter. When the diameter is larger, the starting rod 207 swings more, and when the diameter is smaller, the starting rod 207 swings less. Correspondingly, the moving speed and amplitude of the slider 208 also change. A spray hoop 209 is fixed on the slider 208. The spray hoop 209 moves synchronously with the slider 208 and moves up and down in the interlayer 1014. When the exhaust gas injection rate is faster, the speed of the spray hoop 209 is increased. When the exhaust gas injection rate is slower, the speed of the spray hoop 209 is slowed down to match the exhaust gas injection rate. The nozzle 2091 sprays washing liquid onto the exhaust gas, which can dissolve the colloid and cool the exhaust gas at the same time. The spray hoop 209 is connected to the washing liquid.

[0040] To perform coarse and fine sieving of undissolved colloids, the arc-shaped frame 301 is fixedly mounted on the inner wall of the processing tank 101, positioned above the screen 1012. The arc-shaped frame 301 has a slide rail 3011, and several fan blades 302 are rotatably mounted on the arc-shaped frame 301. A sliding plate 304 is slidably mounted within the slide rail 3011, and has several slots 3041. A limiting rod 303 corresponds to each slot 3041 and is embedded within it. The fixed end of the cylinder 305 is rotatably connected to the inner wall of the processing tank 101, and its telescopic end is rotatably connected to the sliding plate 304.

[0041] The cylinder 305 inside the treatment tank 101 can push the sliding plate 304 to move within the slide rail 3011. When the sliding plate 304 moves, the slot 3041 on the sliding plate 304 moves synchronously. At this time, the limiting rod 303 on the fan blade 302 is embedded in the slot 3041, so the sliding plate 304 will cause the limiting rod 303 to move synchronously. The fan blade 302 is rotatably mounted on the arc frame 301. The sliding plate 304 drives the limiting rod 303 to move, which in turn drives each fan blade 302 to rotate synchronously. This allows adjustment of the opening and closing of the fan blade 302. When exhaust gas is introduced, the fan blade 302 opens a certain space, allowing the washing liquid and exhaust gas to pass through. Heavy large adhesive particles are screened and retained. Due to the spray hoop 2 09 cannot guarantee that all large particles will dissolve during the exhaust gas injection process. Excess large particles remain on the arc frame 301, while exhaust gas and small suspended particles continue to fall into the screen 1012. Small particles cannot pass through the screen 1012, but the washing liquid can pass through and be discharged from the outlet hole 1013. The exhaust gas is discharged through the exhaust tank 102. When the exhaust gas injection is finished, the fan blade 302 is closed, and the nozzle 2091 continues to spray the washing liquid. The washing liquid accumulates on the arc frame 301, covering the large particles of colloid. Using oil, the colloid and organic matter are removed through the principle of "like dissolves like". After complete dissolution, the fan blade 302 is opened, and the particles fall into the screen 1012 to continue dissolving small particles. Then, the particles are discharged from the outlet hole 1013. The washing liquid can be recycled.
