Description

Technical Field

[0001] The invention relates to the technical field of wood vinegar separation, and more specifically to a device for separating wood vinegar from a biomass roasting gas phase product. Background Art

[0002] Wood vinegar is a liquid produced by the high-temperature dry distillation of wood. Its main components are acetic acid, methanol, ethanol and various phenolic compounds.

[0003] The production process needs to be dry distilled and condensed, and then the resulting mixed solution is left to stand to achieve a stratification effect. At this time, the wood vinegar will be in the upper layer, and the water will be in the lower layer. The wood vinegar and water are then pumped out by pumps to obtain wood vinegar and water respectively.

[0004] However, in the process of extracting wood vinegar and water, when the wood vinegar gradually decreases, the wood vinegar near the water part will flow when being extracted, causing a large amount of water to be mixed in the wood vinegar and extracted. At this time, the water content in the wood vinegar will be relatively large, which will increase the distillation time in the subsequent distillation process. When the water is extracted, part of the wood vinegar will be mixed in the water, causing the wood vinegar to be discharged along with a large amount of water, thereby causing waste and affecting production efficiency. The traditional separation device cannot separate the wood vinegar from the water after the wood vinegar and water are layered and then extract the wood vinegar, resulting in an increase in the distillation time. Summary of the invention

[0005] In view of the problems existing in the prior art, the object of the present invention is to provide a device for separating wood vinegar from a biomass roasting gas product.

When the value of the lower liquid concentration meter is different from the value of the upper liquid concentration meter, the data processing module transmits the data to the control module, and the servo motor is controlled to rotate forward through the control module. When the two liquid concentration meters do not detect liquid at the same time, the control module controls the servo motor to rotate reversely.

[0016] Furthermore, a data calculation module is installed outside the separation box, and the electric slide rail transmits the distance data of the slider moving on the electric slide rail to the data calculation module, and the data calculation module calculates the volume of water that can be removed from the separation box by the following formula:

[0042] See also Figures 1 to 9 A device for separating wood vinegar from a gas phase product of biomass roasting comprises a separation box 1, a moving frame 2 is slidably installed inside the separation box 1, two storage chambers 201 are provided inside a side wall of one side of the moving frame 2, the two storage chambers 201 are symmetrically distributed up and down, a rubber sheet 202 is provided inside the storage chamber 201, the end of the rubber sheet 202 passes through the storage chamber 201 and extends to the outside thereof, a sealing groove 203 is provided at a position corresponding to the inner wall of the moving frame 2 and the rubber sheet 202, the outer wall of the rubber sheet 202 is tightly fitted with the inner wall of the sealing groove 203, and the side wall of one side of the separation box 1 is transparent, so as to facilitate observation of the distribution of the solution inside it;

[0043] A driving component 3 is installed on one side of the moving frame 2 away from the storage cavity 201. The driving component 3 drives the end of the rubber sheet 202 to move and pull the rubber sheet 202 out of the storage cavity 201. The driving component 3 includes a moving frame 301 that drives the rubber sheet 202 to move.

[0044] The driving assembly 3 also includes a servo motor 302 embedded in the side wall of the moving frame 2, and a threaded rod 303 threadedly matched with the moving frame 301 is fixedly installed at the output end of the servo motor 302;

[0045] The storage chamber 201 is rotatably connected to a rotating rod 204, the rubber sheet 202 is wound around the rotating rod 204, and coil springs 205 are fixedly installed on the outer walls of both sides of the rotating rod 204, and the other end of the coil spring 205 is fixedly connected to the moving frame 2;

[0046] The inner side wall of the separation box 1 is symmetrically structured and embedded with two electric slide rails 101. The outer wall of the moving frame 2 is fixedly installed with a slider 206 at a position corresponding to the electric slide rail 101. The slider 206 is slidably matched with the electric slide rail 101.

[0047] A water pumping pipe 207 is provided through the upper end of one side of the moving frame 2. The water pumping pipe 207 is in an "L"-shaped structure, and the upper side of the water pumping pipe 207 is in a telescopic structure. A water outlet 102 is provided at the lower side of the separation box 1.

[0048] A slot 208 is provided on the inner wall of one side of the moving frame 2. Two liquid concentration meters 209 for detecting the concentration of the solution in the separation box 1 are provided inside the slot 208. The two liquid concentration meters 209 are symmetrically arranged up and down.

[0049] A data processing module 103 and a control module 104 are installed on the outer wall of the separation box 1. The liquid concentration meter 209 transmits the detected liquid concentration data to the data processing module 103. The data processing module 103 compares the values ​​transmitted by the two liquid concentration meters 209 with the concentration data of water and wood vinegar. When the value of the lower liquid concentration meter 209 is different from the value of the upper liquid concentration meter 209, the data processing module 103 transmits the data to the control module 104, and the servo motor 302 is controlled to rotate forward by the control module 104. When the two liquid concentration meters 209 do not detect liquid at the same time, the control module 104 controls the servo motor 302 to rotate reversely.

[0050] By adopting the above technical solution, when it is necessary to separate the wood vinegar, pour the mixed solution into the separation box 1, and then wait for the water and the wood vinegar to separate. After the water and the wood vinegar are separated, the water will be on the lower side of the separation box 1, and the wood vinegar will be on the upper side of the separation box 1. At this time, the electric slide rail 101 is controlled to drive the slider 206 to rise slowly. When the slider 206 rises, it can drive the moving frame 2 to rise. After the moving frame 2 rises, it can drive the rubber sheet 202 inside it and drive the component 3 to rise. When the moving frame 2 rises to a certain position, the data detected by the liquid concentration meter 209 on the upper side is different from the data detected by the liquid concentration meter 209 on the lower side, the servo motor 302 can drive the threaded rod 303 to rotate. At this time, the electric slide rail 101 is closed, so that the moving frame 2 no longer rises. The rotation of the threaded rod 303 can drive the moving frame 301 to move. After the moving frame 301 moves, it can pull the rubber sheet 202. At this time, the rubber sheet 202 can extend from the storage cavity 201. After extending, 202 can move along the direction of the sealing groove 203, and the outer wall of the rubber sheet 202 can fit with the inner wall of the sealing groove 203. When the rubber sheet 202 seals the upper and lower sides of the movable frame 2, the wood vinegar and the water can be separated. At this time, the staff can extract the wood vinegar out of the separation box 1, and at the same time, the water can be taken out of the separation box 1 through the water outlet 102, so as to complete the collection of the wood vinegar. In addition, after the water and the wood vinegar are extracted from the separation box 1, the mixed solution inside the movable frame 2 can be extracted out of the movable frame 2 through the water extraction pipe 207. When the two liquid concentration meters 209 simultaneously detect that there is no more solution inside the movable frame 2, the control module 104 controls the servo motor 302 to work, thereby driving the threaded rod 303 to rotate in the opposite direction. The reverse rotation of the threaded rod 303 can drive the movable frame 301 to move to the initial position. At this time, the rotating rod 204 can rotate under the action of the coil spring 205, so that the rubber sheet 202 can be rewound around the outside of the rotating rod 204.

[0051] The movable frame 301 is hollow-shaped, and both sides of the movable frame 301 are fixedly connected to two rubber sheets 202. The hollow movable frame 301 can avoid pushing the solution to move over a large area during movement, thereby preventing the mixed solution in the middle of the movable frame 2 from flowing to the upper or lower layer during movement, causing the solution to mix with wood vinegar or water again.

[0052] A data calculation module 105 is installed outside the separation box 1. The electric slide rail 101 transmits the distance data of the slider 206 moving on the electric slide rail 101 to the data calculation module 105. The data calculation module 105 calculates the volume of water that can be removed from the separation box 1 by the following formula:

[0053] ;

[0054] Among them, V 水is the volume of water that can be removed from the separation box 1, M is the bottom area of ​​the separation box 1, H is the distance from the lower end of the electric slide rail 101 to the lower end of the inner wall of the separation box 1, and L1 is the distance between the lower end of the slider 206 and the lower end of the slide rail;

[0055] The data calculation module 105 calculates the volume of the removable wood vinegar separated in the separation box 1 by the following formula:

[0056] ;

[0057] Among them, V 木 is the volume of the separated wood vinegar, V 总 is the total amount of the mixed solution poured into the separation box 1, and H1 is the height of the moving frame 2;

[0058] The data calculation module 105 then calculates the proportion of wood vinegar and the proportion of water separated from the mixed solution in this batch by the following formula based on the volume ratio of the separated water to the volume of the wood vinegar:

[0059] ;

[0060] ;

[0061] Among them, Q 木 is the proportion of wood vinegar separated from this batch of mixed solution, Q 水 It is the proportion of water separated from this batch of mixed solution.

[0062] By adopting the above technical solution, the volume of water and the volume of wood vinegar can be calculated by the data calculation module 105, so as to determine the output of water and the output of wood vinegar. At the same time, the ratio of wood vinegar and water produced by the mixed solution in this batch can be determined according to the output values ​​of multiple groups of wood vinegar and the output values ​​of water, so as to reduce the calculation error.

[0063] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
