Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of biomass modification, and particularly relates to a spraying device and a modification system. BACKGROUND

[0002] Biomass modification refers to a process of treating biomass raw materials by various methods to improve their physical, chemical and biological properties. Common biomass modification methods include physical modification, chemical modification and biological modification, etc. For different application scenarios and implementation targets, appropriate modification technologies need to be selected. Under the premise of using biomass raw materials for gasification, chemical modification method (heat treatment method and impregnation method) is one of the most commonly used modification methods. The heat treatment method heats the raw materials to above 200 DEG C, uses the chemical reaction of biomass structure to evaporate the internal water of the biomass, destroys the fiber structure, and improves the pyrolysis performance of the biomass raw materials. However, the premise of high temperature makes the energy consumption high in industrial production, and the economy is low. The solution impregnation method can remove the ash in the biomass, reduce the alkali metal oxides such as K, Na and Ca in the biomass, and destroy the microstructure of cellulose and hemicellulose, thereby improving the pyrolysis performance of the biomass raw materials. However, since the existing solvent injection device usually adopts intermittent injection mode, the second batch of materials needs to be replaced after the first batch of materials is emptied, the erosion time of the biomass is long, thereby affecting the modification quality and modification efficiency of the biomass, and the continuous operation demand of industrialization cannot be met.

[0037] Figure 1 The structure diagram of the modification system provided by the embodiments of the present application is shown.

[0038] Referring to Figure 1 The modification system 1000 provided by the embodiments of the present application comprises a spraying device 100, a separation device 200, a dissolving device 300 and a filter pressing device 400.

[0039] The spraying device 100 is connected with the dissolving device 300, and the spraying device 100 is used for receiving the second material and can spray the second material with the first material provided by the dissolving device 300 to modify the second material. The modification process of the spraying device 100 is the etching process of the first material to the second material, and the etching of the first material to the second material achieves the purpose of modifying the second material.

[0040] Specifically, the first material can be a liquid material such as water, acid, alkali or organic solvent, and the second material can be a material to be treated such as biomass, coal, ore or waste recycling, and the second material is taken as biomass in the embodiment of the application. Since biomass is generally composed of cellulose, hemicellulose and lignin, the three components have complex structures and are intertwined with each other, so that the biomass has relatively stable properties. Therefore, the second material can be crushed biomass. After the biomass is sprayed and eroded by the first material, the inorganic minerals, organic minerals and organic functional groups in the biomass can be removed, and no other impurities or harmful pollutants are introduced, thereby helping to improve the modification quality of the biomass.

[0041] The separation device 200 is connected to the dissolving device 300, and the separation device 200 is used to separate the decarburization gas from the raw gas and supply the decarburization gas into the dissolving device 300. Specifically, the separation device 200 can be a carbon dioxide separation device in a chemical plant, a coal-fired power plant or a light plant, and the raw gas is waste gas discharged by the chemical plant or synthesis gas used for downstream processes. The carbon dioxide and other gases, smoke, organic matter, nitrogen sulfide and the like in the raw gas can be separated by the carbon dioxide separation device, so that the decarburization gas with high carbon dioxide purity is separated.

[0042] Since the carbon dioxide purity in the decarburization gas is high, the second material is prepared in the dissolving device 300 by using the decarburization gas, which can effectively avoid the generation of pollutants and harmful gases in the dissolving device 300, and helps to improve the modification quality of the biomass in the spraying device 100.

[0043] The dissolving device 300 is connected to the spraying device 100, and the dissolving device 300 can receive water and the decarburization gas supplied by the separation device 200, and prepare the first material based on the decarburization gas and water and supply the first material into the spraying device 100.

[0044] Since the main component in the decarburization gas is carbon dioxide, the carbon dioxide can be fully dissolved in water at room temperature to obtain carbon dioxide aqueous solution (i.e. the first material in the application). The carbon dioxide aqueous solution is an inorganic acid solution and has acidic characteristics. Since the fiber structure and physical properties of the biomass can be decomposed and dissolved under acidic conditions, the carbon dioxide aqueous solution as the first material can not only efficiently change the physical and chemical properties of the biomass in the spraying device 100 at room temperature, such as increasing the carbon content, reducing the oxygen content, reducing the ash content and increasing the hemicellulose content, but also does not need to be pressurized, and the cost is low. Moreover, the decarburization gas based on the chemical plant can be recycled, which not only reduces the carbon emission intensity of the chemical plant, but also solves the problem of carbon emission of the plant from the social benefit level.

[0045] The filter pressing device 400 is connected with the spraying device 100, and is used for receiving the modified material obtained by spraying the first material on the second material for modification, and can perform solid-liquid separation (such as removing a large amount of water in the modified material) on the modified material to obtain a sample. The sample obtained by the filter pressing device 400 can meet the requirements of downstream comprehensive utilization after natural airing.

[0046] It should be noted that the modified material described herein refers to the material obtained by removing inorganic minerals, organic minerals and organic functional groups from the second material after spraying the first material.

[0047] In the modification system 1000 provided in the embodiments of the present application, based on the cooperation of the separation device 200, the dissolving device 300, the spraying device 100 and the filter pressing device 400, the modification of the second material by the first material can be realized under normal temperature conditions, and the modification effect is good and no pollutants and harmful gases are generated in the process, so that the sample meeting the use requirements or the sample meeting the use requirements after simple treatment can be obtained, thereby reducing the cost and improving the biomass modification quality. Moreover, since the devices in the modification system 1000 can perform continuous operation, ton-level biomass raw materials can be processed, and the modification system 1000 is suitable for industrial production, and solves the problems of poor economic benefit and low efficiency of other biomass modification systems from the industrial production level, so that the modification system 1000 based on the present application can greatly improve the biomass modification efficiency.

[0048] Referring to Figure 1 The modification system 1000 provided in the embodiments of the present application can further include a drying device 500 connected with the filter pressing device 400, which is used for drying the sample obtained by the filter pressing device 400, and the sample dried by the drying device 500 can meet the requirements of downstream comprehensive utilization.

[0049] Figure 2 The internal structure of the spraying device provided in the embodiments of the present application is shown in the following figure, Figure 3 The spraying area distribution in the housing of the spraying device in Figure 1 is shown in the following figure.

[0050] Referring to Figure 2 and Figure 3 The spraying device 100 provided in the present application includes a housing 10, a spray head 20 and a transmission component 30.

[0051] The shell 10 forms an internal cavity S and can receive the second material, and the internal cavity S is divided into at least two spraying zones S1. Each spraying zone S1 is provided with at least one spray head 20, and the spray head 20 in each spraying zone S1 is used to spray the first material into the spraying zone S1, so that the segmented spraying effect of the first material on the second material is realized based on the at least two spraying zones S1 and the respective spray heads 20 provided therefor.

[0052] Specifically, the at least two spraying zones S1 are different area portions of the internal cavity S distributed in sequence in the extension direction of the shell 10. For example, the shell 10 can have a cylindrical structure, and the at least two spraying zones S1 are different area portions of the internal cavity S distributed in sequence in the axial direction of the shell 10.

[0053] The shell 10 is provided with a mounting hole in each spraying zone S1, and the spray head 20 is arranged in each spraying zone S1 and mounted on the shell 10 through the mounting hole. In other words, the spray head 20 is at least two in number, and the at least two spray heads 20 are arranged in each spraying zone S1 to provide each spraying zone S1 with a respective spray head 20. In a specific embodiment, the spray head 20 provided in each spraying zone S1 can be arranged at a middle position of the spraying zone S1 in the axial direction of the shell 10.

[0054] The transmission component 30 is at least partially arranged in the shell 10 and penetrates the at least two spraying zones S1, and the transmission component 30 can drive the second material entering the shell 10 to move, so as to transfer the second material between the at least two spraying zones S1, so that the second material can be sprayed by the first material in the at least two spraying zones S1 in sequence.

[0055] In the spraying device 100 provided in the present application, based on the partitioned arrangement of the at least two spraying zones S1 in the shell 10 and the driving effect of the transmission component 30 on the second material, the segmented spraying effect of the first material on the second material can be realized by using the respective spray heads 20 of the at least two spraying zones S1, so that the first material and the second material can be uniformly mixed and fully contacted under normal temperature conditions, which realizes the spatiotemporal decomposition of the physical and chemical structures of the second material, and can sequentially remove inorganic minerals, organic minerals, organic functional groups, etc. in the second material (such as biomass), so as to achieve the purpose of modifying the second material, and can realize continuous operation, thereby improving the modification efficiency of the second material and solving the problems of long immersion time and intermittent processing in other modification devices. Moreover, the modification process (i.e., the immersion process) of the first material and the second material will not corrode the equipment, nor will it introduce other harmful gases and pollutants, thereby solving the equipment corrosion problem in other modification devices.

[0056] Reference Figure 2The transmission component 30 comprises a transmission member 31 and a driving member 32, at least part of the transmission member 31 is arranged in the housing 10 and penetrates through the at least two spraying areas S1, and the driving member 32 is connected with the transmission member 31 and can drive the transmission member 31 to rotate, so as to transmit the second material between the at least two spraying areas S1.

[0057] The driving member 32 is used to provide power for the transmission member 31, which can be a motor or other driving mechanism, and the application does not make specific limitation.

[0058] The transmission member 31 can be arranged in the housing 10 in whole or in part and penetrates through the at least two spraying areas S1, and the transmission member 31 can rotate under the action of the driving member 32, and the rotation of the transmission member 31 can drive the second material to rotate, so as to realize the continuous transmission of the second material between the at least two spraying areas S1.

[0059] Based on the continuous movement mode of the second material rotating and transmitting forward, the second material can be uniformly mixed and fully contacted with the first material sprayed by the corresponding nozzle 20 of each spraying area S1 when reaching each spraying area S1, so as to ensure the spraying and etching effect of the first material on the second material, thereby improving the biomass modification quality and modification efficiency.

[0060] Referring to Figure 2 The transmission member 31 comprises a rotating shaft 311 and a spiral blade 312, the rotating shaft 311 is connected with the driving member 32, and the spiral blade 312 is arranged on the rotating shaft 311 in the axial direction of the rotating shaft 311 and surrounds the rotating shaft 311 to form a spiral groove A. Different parts of the spiral groove A in the axial direction of the rotating shaft 311 correspond to the at least two spraying areas S1 respectively, so that the second material can be transmitted between the at least two spraying areas S1 along the spiral groove A under the action of the driving member 32.

[0061] Based on the arrangement of the rotating shaft 311 and the spiral blade 312, the second material can move along the spiral groove A formed between the rotating shaft 311 and the spiral blade 312, so as to realize the spiral feeding of the second material. Based on the spiral feeding mode of the second material, the feeding path of the second material in the housing 10 is prolonged, so that the movement time of the second material in each spraying area S1 is prolonged, the contact time of the second material with the first material sprayed by the corresponding nozzle 20 of each spraying area S1 is increased, and the spraying and etching effect of the first material on the second material is further improved, thereby improving the biomass modification quality and modification efficiency.

[0062] Figure 4 For Figure 3 The local cross-sectional view at X1-X1.

[0063] Referring to Figures 2 to 4The spray head 20 comprises a nozzle part 21 and a connecting part 22 connected with each other, the connecting part 22 is arranged at one end of the nozzle part 21 away from the transmission part 31, and is used to be connected with the outlet end of the dissolving device 300 to receive the first material. The cross-sectional area of the nozzle part 21 is smaller than that of the connecting part 22.

[0064] Since the cross-sectional area of the nozzle part 21 is smaller than that of the connecting part 22, it is equivalent to that the spray head 20 with the variable diameter structure is adopted and the cross-sectional area of the channel of the first material is reduced at the port position of the spray head 20 in the flow direction of the first material, so that the flow rate of the first material when sprayed out of the spray head 20 can be increased, so that the first material after being sprayed out of the spray head 20 has a large impact force, thereby not only can make the first material uniformly and quickly adhere to the second material to make the leaching process more sufficient, but also can prevent the first material from blocking the spray head 20 and the first material from adhering to the inner side of the shell 10, thereby improving the smoothness of the first material in the flow process and the quality and efficiency of the biomass modification.

[0065] Preferably, the cross-sectional area of the nozzle part 21 in the axial direction of the spray head 20 is arranged to be reduced from the connecting part 22 to the nozzle part 21. In this way, the spray head 20 has a tapered neck structure, which can gradually increase the flow rate of the first material in the nozzle part 21, on the one hand, the first material can have a large flow rate when sprayed out of the spray head 20, on the other hand, the steady increase of the flow rate of the first material can be realized, and the stability of the first material in the flow process can be improved.

[0066] The ratio of the length of the nozzle part 21 in the axial direction of the spray head 20 to the length of the connecting part 22 in the axial direction of the spray head 20 is not less than 0.5. By setting the ratio of the length of the nozzle part 21 in the axial direction of the spray head 20 to the length of the connecting part 22 in the axial direction of the spray head 20 to be not less than 0.5, the flow rate of the first material can be ensured while the first material has a large flow rate and impact force at the moment of spraying to form the optimal spraying effect.

[0067] Referring to Figure 2 In the extension direction of the transmission part 31, the shell 10 is provided with a feeding port B1 and a discharging port B2 for the second material to enter and exit. A flow guide groove C is formed on the inner wall of the shell 10, and the depth of the flow guide groove C is arranged to be gradually deepened from the feeding port B1 to the discharging port B2 in the extension direction of the transmission part 31. An effluent outlet B3 for discharging the first material is arranged at one end of the bottom wall of the flow guide groove C close to the discharging port B2.

[0068] Due to the inclined extension of the inner surface of the bottom wall of the flow guide groove C relative to the extension direction of the transmission member 31 and the gradually decreasing thickness of the bottom wall of the flow guide groove C from the inlet port B1 to the outlet port B2, the depth of the flow guide groove C gradually increases from the inlet port B1 to the outlet port B2, so that the waste liquid in the at least two spray zones S1 after the reaction of the first material and the second material can be collected without obstacles to the waste liquid outlet B3 position in the flow guide groove C and discharged in time through the waste liquid outlet B3.

[0069] The acute angle between the inclined extension direction of the inner surface of the bottom wall of the flow guide groove C and the extension direction of the transmission member 31 is not greater than 5°, so as to avoid the shell being too thick. For example, the acute angle between the inclined extension direction of the inner surface of the bottom wall of the flow guide groove C and the extension direction of the transmission member 31 can be 0.5°, 1°, 1.5°, 2°, 3°, 4°, 5°, etc.

[0070] In other embodiments, the depth of the flow guide groove C can be gradually deepened from the outlet port B2 to the inlet port B1 in the extension direction of the transmission member 31, and the waste liquid outlet B3 for discharging the first material is arranged at one end of the bottom wall of the flow guide groove C close to the inlet port B1; or the flow guide groove C is V-shaped, the depth of the flow guide groove C is gradually deepened from the outlet port B2 and the inlet port B1 to the middle of the two, and the waste liquid outlet B3 for discharging the first material is arranged between the outlet port B2 and the inlet port B1.

[0071] Referring to Figure 3 and Figure 4 Each spray zone S1 is provided with at least two nozzles 20, and the at least two nozzles 20 are arranged in a circumferential direction and opposite to the flow guide groove C. For example, the cross section of the flow guide groove C can be rectangular, and the number of nozzles 20 is three, and the three nozzles 20 are respectively located in the radial direction (opposite to the position of the flow guide groove C), the clockwise 45° direction and the counterclockwise 45° direction of the shell 10.

[0072] Based on the relative position between the at least two nozzles 20 in each spray zone S1 and the transmission member 31, the relative movement between the spray cross section and the spiral direction of the second material is realized, which can significantly increase the contact area of the first material and the second material, so that the first material can fully contact and react with the second material, thereby improving the spraying and etching effect of the first material on the second material.

[0073] Referring to Figure 2 and Figure 3The shell 10 comprises a first end cover 11, a main body 12 and a second end cover 13 connected in sequence in the extension direction of the transmission member 31, and the main body 12 and the first end cover 11 are both provided with the spray head 20. Based on the cooperation between the spray heads 20 on the main body 12 and the first end cover 11, the contact area of the first material and the second material can be further increased, so that the first material can fully contact and react with the second material. In addition, the horizontal force of the solution can prevent the second material from adhering to the inside of the shell and causing blockage.

[0074] With reference to Figure 2 and Figure 3 The spraying device 100 further comprises a filter plate 40 provided with filter holes, and the filter plate 40 is arranged on the inner wall of the shell 10 and covers at least the flow guide groove C. The filter plate 40 allows the waste liquid after the reaction of the first material and the second material in the at least two spraying areas S1 to enter the flow guide groove C, which can prevent the second material from falling into the flow guide groove C and causing poor flow of the waste liquid. Exemplarily, the filter plate 40 is located at the interface between the flow guide groove C and the inner wall of the shell, and the filter plate 40 is in a metal mesh structure as a whole, and the pore size of the filter holes is 1-5mm. For example, the pore size of the filter holes can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, etc.

[0075] Although the embodiments of the present application have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present application, and those skilled in the art can make changes, modifications, replacements and variations to the above embodiments within the scope of the present application.
