Abstract
Description
Technical Field
[0001] This application relates to the field of volatile organic compound vapor adsorption and recovery technology, and more specifically, to an adsorption and recovery treatment device for volatile organic compound vapor. Background Technology
[0002] VOC is the abbreviation for volatile organic compounds. In the general sense, VOC refers to volatile organic compounds. According to the World Health Organization, compounds with a boiling point between 50℃ and 250℃ at room temperature are volatile organic compounds. However, in an environmental sense, VOC refers to a more reactive type of volatile organic compound, that is, the type of volatile organic compound that can cause harm, such as fuel oil.
[0003] In the existing technology (publication number CN105413390B, patent application titled "Adsorption and Pressurization Recovery System for Volatile Organic Compound Vapor in Oil and Gas"), the process of first adsorbing and removing air is simple, has low investment cost, allows for direct observation of the recovered liquid oil, and is highly safe. However, in implementing this technical solution, at least the following problems were found in the existing technology.
[0004] In environmental monitoring, volatile organic compound (VOC) vapors are recycled for energy conservation and environmental protection. However, most current recycling devices can only perform single-stage fixed adsorption separation of VOC vapors, resulting in unsatisfactory separation of oil and gas and waste gas in the VOC vapors. This leads to low VOC vapor recovery efficiency and substandard purity, which is detrimental to the implementation of environmental monitoring work. Summary of the Invention
[0005] This application aims to at least address the technical problem in existing technologies where the combination of counter-adsorption and temperature-controlled desorption cannot effectively separate oil and gas from volatile organic compound (VOC) vapors, resulting in low VOC vapor recovery efficiency and purity. Therefore, this application proposes an adsorption and recovery treatment device for VOC vapors.

[0007] The inner sides of the two sets of treatment tanks are fixedly connected to a fixing frame, and the inner cavity of the fixing frame is provided with an adsorption component that works with the treatment tank;
[0008] The outer side of the fixing frame is provided with a desorption assembly for use with the treatment tank.
[0009] Preferably, the adsorption assembly includes a dual-head motor, which is fixed inside the fixed frame. The two output shafts of the dual-head motor are fixedly connected to a swing arm. A lifting frame is slidably connected to the other side of the swing arm. A connecting rod is fixedly connected to both the upper and lower sides of the lifting frame. A piston that slides with the fixed frame is fixedly connected to the side of the connecting rod away from the lifting frame. A support arm is fixedly connected to the side of the piston away from the connecting rod. A frame that slides with the treatment tank is fixedly connected to the other side of the support arm. Adsorption boxes are provided on both the upper and lower sides of the inner cavity of the frame. A hydrophobic silica gel frame and an activated carbon frame are respectively embedded in the inner cavity of the adsorption box.
[0010] Preferably, the desorption assembly includes a heating and cooling unit, which is fixed to the bottom of the mounting frame. The two outlets of the heating and cooling unit are connected to a conveying pipe. The end of the conveying pipe away from the heating and cooling unit is connected to a three-way valve, and both ends of the three-way valve are connected to four-way valves. The two inlets of the four-way valve are connected to a pressurizing pipe that works with the mounting frame, and one outlet of the four-way valve is connected to a supply pipe. The end of the supply pipe away from the four-way valve is connected to a conveying hood that works with the treatment tank. The front and rear sides of the treatment tank are both fitted with flow equalization nets that work with the conveying hood.
[0011] Preferably, the two sets of support arms are fitted with buffer springs for use with the treatment tank on the side away from the fixed frame, and the hydrophobic silica gel frame and activated carbon frame are distributed in a circumferential shape along the central axis of the adsorption box.
[0012] Preferably, the two sets of skeletons are rotatably connected to a baffle fan blade for use with the treatment tank near the center of the activated carbon frame, and the baffle fan blade adopts a streamlined design.
[0013] Preferably, guide rails are provided around the inner cavities of both sets of processing tanks, and guide rail blocks that are fixedly connected to the skeleton are slidably connected to the inner cavities of the guide rails.
[0014] Preferably, slide rails are provided on both the front and rear sides of the inner cavity of the two sets of fixed frames, and slide rail strips that are fixedly connected to the inner cavity of the slide rails are slidably connected to the lifting frame.

Simultaneously, two sets of support arms and a frame drive the hydrophobic silica gel and activated carbon frames within the two sets of adsorption boxes to reciprocate up and down within the two sets of treatment tanks. This double-impact adsorption process effectively separates the oil and gas and waste gas from the VOC vapors, improving the efficiency of VOC vapor recovery. The system improves recovery efficiency and purity by providing heat and cold sources through an integrated heating and cooling unit in the desorption assembly. After being pressurized by two sets of pressure pipes via two sets of conveying pipes, three-way valves, and four-way valves, the system then provides a uniform cooling source to two sets of processing tanks via two sets of supply pipes and conveying hoods through two sets of flow equalization nets. This efficiently desorbs the oil and gas adsorbed within the two sets of reciprocating hydrophobic silica gel and activated carbon frames, separating the oil and gas. By combining counter-adsorption and temperature-controlled desorption, the system effectively separates oil and gas from volatile organic compound vapors, improving the recovery efficiency and purity of volatile organic compound vapors and facilitating environmental monitoring.

[0041] like Figures 1-12 As shown, an adsorption and recovery treatment device for volatile organic vapors according to an embodiment of this application includes: a treatment tank 1, two inlets in the middle of two sets of treatment tanks 1 are connected to a Y-shaped feed pipe 2, and a control valve is provided at the end of the Y-shaped feed pipe 2 away from the treatment tank 1 to control the opening and closing of the volatile organic vapor material entering the Y-shaped feed pipe 2.
[0042] The drain ports of the two sets of treatment tanks 1 are connected to drain pipes 13, and an electric control valve is installed at one end of the drain pipe 13 near the treatment tank 1 to discharge the condensed oil in the two sets of treatment tanks 1. The oil and gas outlets of the two sets of treatment tanks 1 are connected to Y-shaped oil and gas pipes 14, and a first check valve is installed at the end of the Y-shaped oil and gas pipes 14 to discharge the oil and gas that have separated from the two sets of treatment tanks 1. The exhaust gas outlets of the two sets of treatment tanks 1 are connected to Y-shaped exhaust gas pipes 15, and a second check valve is installed at the end of the Y-shaped exhaust gas pipes 15 to discharge the exhaust gas that has separated from the two sets of treatment tanks 1.
[0043] The inner sides of the two sets of treatment tanks 1 are fixedly connected to the fixing frame 3, and the top of the inner side of the fixing frame 3 is fixedly connected to the alarm light to warn of the equipment operating status. The inner cavity of the fixing frame 3 is equipped with an adsorption component 4 that works with the treatment tank 1 to adsorb and separate oil and gas and waste gas in volatile organic vapor materials.
[0044] The outer side of the fixed frame 3 is equipped with a desorption component 5 that works in conjunction with the treatment tank 1 to desorb the oil and gas adsorbed in the volatile organic vapor material, thereby completing the separation and recovery of oil and gas.
[0045] like Figures 5 to 9As shown, in the process of environmental monitoring, in order to save energy and protect the environment, volatile organic compound vapors are recycled. However, most of the current recycling devices can only perform single fixed adsorption separation of volatile organic compound vapors. They cannot use a combination of counter-adsorption and temperature-controlled desorption to effectively separate oil and gas and waste gas in volatile organic compound vapors, resulting in low efficiency and purity of volatile organic compound vapor recovery. The adsorption component 4 includes a dual-head motor 41, which is fixed inside the fixing frame 3 and provides a unified drive source.
[0046] Furthermore, the two output shafts of the dual-head motor 41 are fixedly connected to the swing arm 42, and the other side of the swing arm 42 is slidably connected to the lifting frame 43. The upper and lower sides of the lifting frame 43 are fixedly connected to the connecting rod 44, and the side of the connecting rod 44 away from the lifting frame 43 is fixedly connected to the piston 45 that slides with the fixed frame 3. The two sets of swing arms 42 drive the piston 45 on the two sets of connecting rods 44 to reciprocate within the two sets of fixed frames 3 to perform work and generate increased pressure.
[0047] Furthermore, a support arm 46 is fixedly connected to the side of the piston 45 away from the connecting rod 44, and a frame 47 that slides with the treatment tank 1 is fixedly connected to the other side of the support arm 46. Adsorption boxes 48 are provided on both the upper and lower sides of the inner cavity of the frame 47. The inner cavity of the adsorption box 48 is respectively embedded with a hydrophobic silica gel frame 49 and an activated carbon frame 410. The two sets of support arms 46 and the frame 47 drive the hydrophobic silica gel frame 49 and the activated carbon frame 410 in the two sets of adsorption boxes 48 to move up and down in the two sets of treatment tanks 1, so as to perform double counter-current adsorption on the volatile organic vapors flowing into the two sets of treatment tanks 1, effectively separating the oil and gas and the waste gas in the volatile organic vapors, improving the recovery efficiency and purity of volatile organic vapors, and also facilitating the implementation of environmental monitoring work.
[0048] Two sets of support arms 46 are fitted with buffer springs 7 on the side away from the fixed frame 3, which are used in conjunction with the treatment tank 1. The two sets of support arms 46 provide elastic buffering for the reciprocating lifting action. The hydrophobic silica gel frame 49 and activated carbon frame 410 are distributed in a circular shape along the central axis of the adsorption box 48, so as to uniformly and comprehensively adsorb and remove oil and gas and waste gas in volatile organic vapor materials.
[0049] Two sets of frames 47 are rotatably connected to the center of the activated carbon frame 410, and are used in conjunction with the treatment tank 1. The turbulence fan blades 8 are streamlined and play a turbulence role in the volatile organic vapor material flowing into the two sets of treatment tanks 1, so that the volatile organic vapor material flows into the hydrophobic silica gel frame 49 and the activated carbon frame 410. Guide rails 9 are provided around the inner cavity of the two sets of treatment tanks 1, and guide rail blocks 10 that are fixedly matched with the frame 47 are slidably connected to the inner cavity of the guide rails 9, providing sliding limit compensation for the frame 47 and improving the reciprocating lifting stability of the frame 47. Slide rails 11 are provided on the front and rear sides of the inner cavity of the two sets of fixed frames 3, and slide rail strips 12 that are fixedly matched with the lifting frame 43 are slidably connected to the inner cavity of the slide rails 11, which play a sliding support role for the lifting frame 43 to prevent the lifting frame 43 from tilting and shaking during the lifting action.
[0050] The desorption assembly 5 includes a heating and cooling unit 51, which is fixed to the bottom of the mounting frame 3. The heating and cooling unit 51 provides the heat source and cold source supply. The two outlets of the heating and cooling unit 51 are connected to the conveying pipe 52. The end of the conveying pipe 52 away from the heating and cooling unit 51 is connected to the three-way valve 53. Both ends of the three-way valve 53 are connected to the four-way valve 54. The two inlets of the four-way valve 54 are connected to the pressurization pipe 55 used in conjunction with the mounting frame 3. The outlet of the four-way valve 54 is connected to the supply pipe 56. The end of the supply pipe 56 away from the four-way valve 54 is connected to the conveying cover 57 used in conjunction with the processing tank 1.
[0051] Furthermore, both the front and rear sides of the treatment tank 1 are equipped with flow equalization nets 58 that communicate and cooperate with the conveying hood 57. After being pressurized by two sets of conveying pipes 52, three-way valves 53 and four-way valves 54 through two sets of pressurizing pipes 55, the two sets of supply pipes 56 and conveying hood 57 provide a uniform cold source or cold source to the two sets of treatment tanks 1 through the two sets of flow equalization nets 58. This efficiently desorbs the oil and gas adsorbed in the two sets of hydrophobic silica gel racks 49 and activated carbon racks 410 that move up and down, thus separating the oil and gas. By adopting a combination of counter-adsorption and temperature-controlled desorption, the oil and gas in the volatile organic vapor are effectively separated, thereby improving the recovery efficiency and purity of the volatile organic vapor.
[0052] like Figure 10 and Figure 11As shown, during the adsorption and recovery of volatile organic compound vapors, a reciprocating pressure filtration method cannot be used to further separate the separated oil and gas and waste gas, resulting in the presence of mixed residues in the treated oil and gas and waste gas. A filter assembly 6 is installed at the bottom of the Y-type oil and gas pipe 14 and the Y-type waste gas pipe 15. The filter assembly 6 includes an upper end cover 61. Two sets of upper end covers 61 are respectively connected to the bottom of the Y-type oil and gas pipe 14 and the Y-type waste gas pipe 15. An upper filter membrane 62 is installed in the inner cavity of the upper end cover 61 to perform primary filtration on the desorbed oil and gas and waste gas, and to separate the mixed residues in the desorbed oil and gas and waste gas.
[0053] The bottom ends of the two sets of upper end caps 61 are connected to telescopic sleeves 63, and the bottom ends of the telescopic sleeves 63 are connected to lower end caps 64. The inner cavities of the two sets of lower end caps 64 are provided with lower filter membranes 65 that cooperate with the upper filter membranes 62 to perform secondary filtration on the desorbed oil and gas and exhaust gas, and to further separate the mixed residual substances in the desorbed oil and gas and exhaust gas to obtain pure oil and gas and exhaust gas.
[0054] The bottom ends of the two sets of lower end caps 64 are connected to telescopic pipes 66, which play a role in adjusting the stroke of the telescopic sleeves 63 that move up and down. The telescopic sleeves 63 can move up and down with the telescopic sleeves 63. The inner side of the lower end caps 64 is fixedly connected to a cross-shaped frame 67, which is fixedly connected to the support arm 46 located below. The support arm 46 located below drives the telescopic sleeves 63 and telescopic pipes 66 on the two sets of lower end caps 64 to reciprocate and extend, thereby accelerating the flow speed of oil and gas and exhaust gas in the two sets of telescopic sleeves 63 and telescopic pipes 66 to prevent turbulence and blockage. The bottom ends of the two sets of telescopic pipes 66 are respectively connected to oil and gas discharge pipes 68 and exhaust gas discharge pipes 69, which discharge the pure oil and gas and exhaust gas after two-stage separation.
[0055] Specifically, the working principle of this volatile organic compound vapor adsorption and recovery treatment device is as follows: When recovering and utilizing the generated volatile organic compound vapor, the volatile organic compound vapor material is first conveyed to the middle space of the two sets of treatment tanks 1 through the Y-shaped feed pipe 2. Then, the double-head motor 41 is turned on and drives the two sets of swing arms 42 to rotate. The two sets of slide rails 11 and slide rail strips 12 provide sliding support compensation for the two sets of lifting frames 43. The two sets of swing arms 42 drive the two sets of lifting frames 43 to perform reciprocating lifting and lowering actions. The two sets of lifting frames 43 then drive the pistons 45 on the two sets of connecting rods 44 to perform reciprocating work in the reserved sealed cavity of the two sets of fixed frames 3 and generate increased pressure. While the two sets of pistons 45 are performing reciprocating work, the two sets of guide rails 9 and guide rail blocks 10 provide sliding limit compensation for the two sets of skeletons 47. The two sets of reciprocating pistons 45 also drive the skeletons 47 on the two sets of support arms 46 to perform reciprocating lifting and lowering actions in the upper and lower positions of the two sets of treatment tanks 1.
[0056] Two sets of buffer springs 7 provide elastic buffering compensation for the two sets of support arms 46 reciprocating up and down. At the same time, the two sets of skeletons 47 drive the hydrophobic silica gel racks 49 and activated carbon racks 410 in the two sets of adsorption boxes 48 to reciprocate up and down in the two sets of treatment tanks 1. The two sets of skeletons 47 also drive the two sets of turbulence fan blades 8 to reciprocate up and down, and generate height and gravity difference, forcing the two sets of turbulence fan blades 8 to rotate in the middle space of the two sets of treatment tanks 1. While turbulently treating the incoming volatile organic vapor material, the hydrophobic silica gel racks 49 and activated carbon racks 410 in the two sets of adsorption boxes 48 reciprocate up and down to convectively adsorb the oil and gas in the incoming volatile organic vapor material. After the oil and gas in the volatile organic vapor material are adsorbed, the waste gas separated by the two sets of hydrophobic silica gel racks 49 and activated carbon racks 410 enters the Y-shaped waste gas pipe 15 at the top of the two sets of treatment tanks 1.
[0057] During the adsorption and separation of oil and gas and waste gas in volatile organic compound vapor materials, the integrated cooling and heating unit 51 is turned on in advance to generate a cold source. The generated cold source is divided into two routes: two sets of conveying pipes 52, two sets of three-way valves 53, and two sets of four-way valves 54. At the same time, the boosted pressure generated in the reserved sealing cavities of the two sets of fixed brackets 3 is also supplied to the two sets of four-way valves 54 through two sets of pressurizing pipes 55 and merges with the cold source to form two boosted cold sources. The two boosted cold sources are then supplied by two sets of supply pipes 56 through two sets of conveying covers. After the flow equalization treatment by the flow equalization net 58 on 57, the flow is supplied into the two sets of treatment tanks 1. The incoming volatile organic vapor material is pressurized and cooled, so that the hydrophobic silica gel rack 49 and activated carbon rack 410 in the two sets of adsorption boxes 48 that move up and down can effectively adsorb the oil and gas in the volatile organic vapor material. At the same time, the waste gas in the cooled volatile organic vapor material is quickly pressurized and separated into the Y-shaped waste gas pipe 15. Meanwhile, the oil condensed in the two sets of treatment tanks 1 is discharged from the two sets of drain pipes 13.
[0058] After the exhaust gas in the volatile organic compound vapor material is discharged, the integrated cooling and heating unit 51 is turned on and generates a heat source. Similarly, the generated heat source is divided into two routes: two sets of conveying pipes 52 pass through two sets of three-way valves 53 and enter two sets of four-way valves 54. At the same time, the boosted pressure generated in the reserved sealing cavity of the two sets of fixed frames 3 is also supplied into the two sets of four-way valves 54 through two sets of pressurizing pipes 55 and merges with the heat source to form two boosted heat sources. The two boosted heat sources are then supplied into the two sets of treatment tanks 1 through two sets of supply pipes 56 and flow equalization nets 58 on two sets of conveying covers 57. The oil and gas adsorbed in the hydrophobic silica gel frame 49 and activated carbon frame 410 of the two sets of adsorption boxes 48 that move up and down are heated and separated, so that the separated oil and gas enter the Y-shaped oil and gas pipe 14. At the same time, the oil liquid condensed in the two sets of treatment tanks 1 is discharged through two sets of drain pipes 13.
[0059] In the volatile organic compound vapor material, the oil and gas and exhaust gas first enter the Y-shaped oil and gas pipe 14 and the Y-shaped exhaust gas pipe 15 respectively, and then enter the two sets of telescopic sleeves 63 between the two sets of upper end caps 61 and lower end caps 64. At the same time, the first one-way valve and the second one-way valve on the oil and gas discharge pipe 68 and the exhaust gas discharge pipe 69 are opened. Simultaneously, the two sets of support arms 46 located below and in a reciprocating lifting state drive the two sets of lower end caps 64 to move up and down through the cross-shaped frame 67, and drive the two sets of telescopic sleeves 63 to enter the oil and gas vapor material. The incoming oil and gas and exhaust gas reciprocate, forcing them to flow rapidly within the reciprocating telescopic sleeve 63. The residual substances mixed in the flowing oil and gas are then filtered in two stages by the upper filter membrane 62 of the two sets of upper end caps 61 and the lower filter membrane 65 of the two sets of lower end caps 64. The purified oil and gas after the two stages of separation are then discharged by the telescopic pipe 66, which follows the reciprocating motion of the two sets of telescopic sleeves 63, through the oil and gas discharge pipe 68 and the exhaust gas discharge pipe 69 respectively.
