Description

Technical Field

[0001] The invention relates to the technical field of gas separation, and in particular to a detoxification treatment auxiliary device for raw coal gas conversion treatment. Background Art

[0002] The raw coal gas treatment technology converts the raw coal gas into high-value synthesis gas with hydrogen and carbon monoxide as the main components through a series of clean and efficient utilization processes such as compression and washing, conversion, transformation, low-temperature methanol washing, PSA adsorption separation, etc., and separates and purifies it. It then uses carbonylation, hydrogenation and refining technology to finally produce high-end chemical product polyester-grade ethylene glycol, which produces good environmental and economic benefits.

[0003] In the prior art, since the raw gas contains a large amount of harmful substances such as dust and tar, detoxification treatment is required to ensure the long-term operation of the treatment process. At present, detoxification is usually carried out by spraying washing liquid. First, the raw gas is introduced from the bottom of the tower, and passes through the filler and spray area in turn. After multiple layers of washing, the detoxified raw gas is finally discharged into the next process for treatment. During the washing process, for small particle size and high concentration of dust, finer spray particles may be required to improve the collision and adsorption efficiency. Conversely, for large particle size and low concentration of dust, larger spray particles may be more suitable. Tar usually has high viscosity and adhesion, and larger spray particles may be required to enhance the flushing and stripping effects. However, the current spray droplet particle size is usually relatively uniform. For raw gas with different harmful substance contents, larger droplets are used for spraying, which makes the amount of washing liquid larger, and the processing capacity requirements for the circulation system are also higher, which increases the production cost.

[0004] In addition, during the washing process, the traditional filler setting is not only prone to clogging after long-term use, but once blocked, the air filtration effect is extremely low. When replacing the filler, it is necessary to first clean up the accumulated filler and then evenly lay the new filler. The replacement and maintenance process is cumbersome and time-consuming, affecting the efficiency of the detoxification treatment.

[0005] In view of this, the present invention proposes a detoxification treatment auxiliary equipment for raw gas conversion treatment to make up for and improve the shortcomings of the prior art. Summary of the invention

[0010] Preferably, the speed changing rotating mechanism also includes a rotating ring fixedly connected to the top of the impeller, the inner walls of the multiple rotating rings are rotatably connected to the outer wall of the fixed rod, the outer wall of the rotating ring is fixedly connected to multiple support rods at equal intervals around the circumference, and the bottom of the support rods is fixedly connected to multiple diffuser blades.

[0011] Preferably, the double-rotation contact mechanism includes a rotating rod rotatably connected to the side of the support rod away from the swivel, a plurality of thin rods are fixedly connected on both sides of the middle part of the rotating rod, and a pair of power assisting plates are fixedly connected in opposite directions on the upper and lower sides of the rotating rod.

[0015] Preferably, the air jet head and the spray head are both arranged toward the impeller.

[0016] Preferably, the nozzles are all arranged toward the center of the liquid injection ring.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the process of washing the raw gas, the impeller is driven by the setting of the variable speed rotating mechanism, in which both the jet head and the spray head spray in the direction of the impeller, and the diffusion blades tilted outward rotate and move, so that the mist and raw gas gathered in the impeller area gradually fill the inner cavity of the detoxification tower body. Only a single mist source spray head is set in the middle, and fine mist is sprayed, which not only saves the use of washing liquid and reduces the processing pressure of the circulating water tank, but also improves the efficiency of installation and maintenance, thereby reducing production costs. In addition, the auxiliary diffusion blades as a power source disperse the mist and raw gas into the cavity of the detoxification tower body, which can effectively avoid the occurrence of uneven jetting or spraying, and the mist is released in layers at the top of the detoxification tower body, so that the raw gas moving from bottom to top can be fully detoxified, thereby enhancing the treatment effect of the raw gas; 2. The nozzles are all arranged toward the center of the injection ring, so that the airflow blown by the fan blades plays a key role in the spraying of the mist. The faster airflow speed can make the fine mist collide and combine to form a larger particle size mist. Therefore, the change of the fan blade speed can control the size of the mist particles blown out by the spray head, so that the harmful substances in different batches of raw gas can be effectively washed, and the detoxification treatment efficiency is improved. When the fan blade speed is changed, the speed of the impeller will also change. When the wind speed is high, the impeller rotates faster, and the raw gas and mist can be quickly diffused through the diffusion blades. When the wind speed is low, the impeller rotates relatively slowly, the mist is fine, and it also takes more time to contact and react with the raw gas. The reasonable structural distribution improves the reliability of the device operation; 3. Through the setting of the double-rotation contact mechanism, the auxiliary plate is used in conjunction with the rotating rod inclined outward, so that the rotating rod rotates around the fixed rod and also rotates by itself. The densely distributed thin rods in the middle of the rotating rod can continuously stir the raw gas and washing liquid mist diffused into the inner cavity of the detoxification tower body. The thin rods can also reduce the adsorption of mist, avoid reducing the concentration of mist, and do not hinder the equilibrium state of the mutual reaction between the two, so as to achieve effective contact between the raw gas and the mist and enhance the washing effect. 4. Through the setting of the detachable filter plate, since the height of the telescopic ring is consistent with the position of the visual door, the staff can open the visual door and directly replace the new filter plate. The process is simpler and saves operation time. In addition, during the rotation of the filter plate, the mixed pollutants that have been reacted are intercepted, and the clean gas can pass through the filter plate. The multi-layer filter plates fully intercept the reacted mixed pollutant particles, so that the raw gas moving upward can not only be effectively detoxified, but also avoid being blocked, thereby improving the work efficiency of the detoxification treatment.

Both are existing technologies and will not be elaborated on. The diffusion blade 610 is used to disperse the mist and raw coal gas gathered in the middle to the outside.

[0022] The effects achieved by this embodiment are as follows: In the prior art, the particle size of the current spray droplets is usually relatively uniform. For raw coal gases with different harmful substance contents, larger droplets are used for spraying, which results in a larger amount of washing liquid, a higher processing capacity requirement for the circulation system, and an increased production cost. Compared with the prior art, through the implementation of this embodiment, the variable speed rotating mechanism 6 is set to be able to use the jet head 67 and the spray head 68 to spray in the direction of the impeller 62, drive the impeller 62, and rotate and move with the diffusion blades 610 inclined outward, so that the mist and raw coal gas gathered in the impeller 62 area gradually fill the inner cavity of the detoxification tower body 1, and only a single mist source spray head 68 is set in the middle to spray fine mist, which not only saves the use of washing liquid and reduces the processing pressure of the circulating water tank 3, but also improves the efficiency of installation and maintenance, and reduces production costs.

[0023] Further examples: Please refer to Figure 2 , Figure 3 , Figure 5 , Figures 8 to 10As shown, the double-rotation contact mechanism 7 includes a rotating rod 73 rotatably connected to the side of the support rod 611 away from the rotating ring 69, a plurality of thin rods 74 are fixedly connected to both sides of the middle of the rotating rods 73, and a pair of assisting plates 75 are fixedly connected to the upper and lower sides of the rotating rods 73 in opposite directions; The double-rotation contact mechanism 7 also includes a plurality of groove plates 76 fixedly connected to the top of each rotating ring 69, and the tops of the plurality of groups of groove plates 76 are slidably connected with telescopic rings 71, and the inner walls of the plurality of telescopic rings 71 slide on the outer wall of the fixed rod 65, and the inner cavities of the telescopic rings 71 are fixedly connected with a plurality of return springs 77, and the ends of the return springs 77 away from the telescopic rings 71 are fixedly connected to the tops of the groove plates 76, and the middle parts of the groove plates 76 are provided with two groups of card slots 78, and the inner walls of the groove plates 76 are slidably connected with filter plates 72, and the plurality of filter plates 72 are fixedly connected with two groups of card blocks 79 on one side close to the groove plates 76, and the outer walls of the card blocks 79 are slidably connected to the card slots 78; The rotating rods 73 are all tilted outwards, and the assisting plates 75 and the thin rods 74 are all vertically arranged; Among them: the speed-changing rotating mechanism 6, the double-rotation contact mechanism 7 and the visual door 2 are set in the same number of groups, the height of the telescopic ring 71 is set to be consistent with the position of the visual door 2, the thin rods 74 are densely distributed on the surface of the rotating rod 73, and the thin rods 74 and the power-assisting plate 75 are vertically arranged to keep the rotating rod 73 with a balanced distribution of gravity for rotation.

[0024] The effects achieved by this embodiment are as follows: In the prior art, the setting of traditional fillers is not only prone to clogging after long-term use, but also has extremely low air filtering effect once blocked. In addition, when replacing the fillers, it is necessary to first clean up the accumulated fillers and then evenly lay new fillers. The replacement and maintenance process is cumbersome and time-consuming, which affects the work efficiency of the detoxification treatment. Compared with the prior art, through the implementation of this embodiment, a double-rotation contact mechanism 7 is set, and a power-assisting plate 75 is used in conjunction with a rotating rod 73 tilted outward, so that the rotating rod 73 rotates when rotating around the fixed rod 65, and the densely distributed thin rods 74 in the middle of the rotating rod 73 can continuously stir the raw gas and washing liquid mist diffused into the inner cavity of the detoxification tower body 1. The thin rods 74 can also reduce the adsorption of the mist, avoid reducing the mist concentration, and do not hinder the equilibrium state of the mutual reaction between the two, thereby achieving effective contact between the raw gas and the mist and enhancing the washing effect.

[0025] The complete usage steps and working principle of the above embodiment are as follows: In the initial state: the impeller 62 is in a stationary state, the clamping block 79 is clamped in the clamping groove 78, and the return spring 77 is in a naturally relaxed state.

[0026] When in use, the staff starts the pump unit in the circulating water tank 3, and the washing liquid is transported to the branch pipe 63 through the liquid inlet pipe 66, and then dispersed into the nozzle 614 through the liquid injection ring 612, and sprayed into fine mist under pressure. Since the nozzles 614 are all arranged toward the center of the liquid injection ring 612, the mist will be dispersed outward through the outlet of the spray head 68 after being sprayed. At this time, the small motor 615 is started by the external control system to rotate the fan blade 613, and the mist is quickly blown out of the spray head 68, and the work is done at the same time. The personnel opens the valve of the air inlet pipe 61 to release the raw gas under pressure, and blows it into the detoxification tower body 1 through the nozzle 67. Since the nozzle 67 and the spray nozzle 68 are both arranged in the direction of the impeller 62, when the two continue to blow out the mist and raw gas, the impeller 62 can be blown to rotate, and then the impeller 62 drives the rotating ring 69 to rotate synchronously. When the rotating ring 69 rotates, it can drive the support rod 611 to rotate synchronously, and the diffusion leaf 610 fixed at the bottom of the support rod 611 and tilted outward also rotates and moves accordingly, so that the focusing The mist and raw gas in the impeller 62 area are continuously driven by the diffusion blades 610 in the direction away from the impeller 62, filling the inner cavity of the detoxification tower body 1. Similarly, the multiple spray heads 68 above can also blow out mist to rotate the upper impeller 62, increase the mist concentration at the top of the detoxification tower body 1, so that the raw gas at the bottom is filtered by multiple layers of mist, and harmful substances such as dust and tar are left in the mist to form mixed pollutants. The raw gas enters from the bottom air inlet pipe 61 and is discharged from the top exhaust assembly 4. It is discharged from the bottom to the top in the detoxification tower body 1. Move upward, after passing through multiple layers of washing liquid mist, the harmful substances therein are gradually washed and removed, and the clean raw gas is extracted from the top of the detoxification tower body 1 by the exhaust assembly 4 after passing through the demister plate 5, and enters the next treatment step. Because each layer is provided with only one mist source spray head 68, it not only improves the efficiency of installation and maintenance, but also can be used as the power to drive the impeller 62, assist in speed change, and cooperate with the diffusion blade 610 to allow the mist and the raw gas sprayed from the spray head 67 to diffuse together, avoiding the situation of uneven spraying or spraying; Furthermore, during the spraying process, since the mist is dispersed into fine droplets suspended in the air through pressurized liquid, using the fan blades 613 to blow the airflow can increase the movement activity of the droplets. Generally, the faster the wind speed, the faster the droplets move, and the closer the droplets are to the fan blades 613, the faster the droplets move. The mist continuously sprayed out from the back of the nozzle 614 will accelerate and collide with the mist sprayed in the front, increasing the mutual collision between the droplets, so that the fine mist combines to form a larger particle size mist. Therefore, the rotation speed of the small motor 615 can be changed through an external control system, so that the speed of the fan blades 613 stirring the airflow changes, and finally the size of the mist particles blown out by the spray head 68 is controlled to make the waste gas small particle size. When the dust content is high, fine mist is used, and when the tar content is high, mist with relatively large particle size is used, so that the harmful substances in different batches of raw gas can be effectively washed, improving the detoxification treatment efficiency, and targeted control of the particle size of the mist can effectively reduce the use of washing liquid and reduce the processing pressure of the circulating water tank 3, thereby saving production costs. In addition, when the speed of the fan blade 613 is changed, the rotation speed of the impeller 62 will also be changed. When the wind speed is high, the rotation speed of the impeller 62 is accelerated, and the raw gas and mist can be quickly diffused. When the wind speed is low, the rotation speed of the impeller 62 is relatively slow, and the mist is fine, and it also takes more time to contact and react with the raw gas. The reasonable distribution of the structure improves the reliability of the device operation; Please refer to the above working process Figures 1 to 7 .

[0027] When the impeller 62 drives the swivel 69 and the support rod 611 to rotate, the swivel rod 73 connected to the end of the support rod 611 is also driven to rotate around the fixed rod 65. Since the swivel rod 73 is tilted outward, the assisting plates 75 on both sides of the swivel rod 73 cause the swivel rod 73 to continuously rotate due to the resistance of the airflow during rotation, thereby causing the thin rod 74 located in the middle of the swivel rod 73 to rotate around the swivel rod 73 as the axis. The dense distribution of the thin rods 74 can continuously stir the raw gas and washing liquid mist diffused into the inner cavity of the detoxification tower body 1. The thin rods 74 can also reduce the adsorption of the mist, avoid reducing the concentration of the mist, and do not hinder the equilibrium state of the mutual reaction between the two. At the same time, the groove plate 76 on the top of the swivel 69 and the telescopic ring 71 also rotate synchronously with the swivel 69, and the multiple filter plates 72 connected to the groove plate 76 also rotate synchronously around the fixed rod 65. During the rotation process, the filter plates 72 The filter plate 72 is then removed from the housing 70 by the spring 77. The filter plate 72 is then removed from the housing 70 by the spring 77. Please refer to the above working process Figure 2 , Figure 3 , Figure 5 , Figures 8 to 10 .
