[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, an emission reduction device for palmitic acid oil processing includes a biodiesel production component 1, which is used to convert pretreated palmitic acid oil into biodiesel, using the palmitic acid oil and methanol to undergo an esterification reaction under the action of a catalyst (such as concentrated sulfuric acid) to produce biodiesel. A filter component 2 is fixed on the upper end of the biodiesel production component 1, and the filter component 2 is used to remove impurities in the palmitic acid oil to improve the quality of the raw material. A feed component 3 is fixed on the upper end of the filter component 2, and the feed component 3 is used to intermittently transport the palmitic acid oil into the filter component 2;

[0026] Among them, a wastewater treatment component 4 adapted to the biodiesel production component 1 is provided on the left side of the biodiesel production component 1. The wastewater treatment component 4 is used to treat the wastewater in the biodiesel production component 1 to reduce the content of pollutants and meet the emission standards.

[0027] Further, if Figure 2 and Figure 3 As shown, the feed component 3 includes a feed pipe 30, a mounting block 31 is fixed at the lower end of the feed pipe 30, and the mounting block 31 is fixedly connected to the filter component 2. A motor 32 is fixed to the rear end of the mounting block 31. A cylindrical groove 33 is provided inside the mounting block 31. The cylindrical groove 33 is a cylindrical groove, and its upper portion corresponds to the feed pipe 30, so that the inner cavity of the feed pipe 30 is connected to the inner cavity of the cylindrical groove 33. The lower end of the mounting block 31 is provided with two symmetrical flow grooves 34. The two flow grooves 34 are inclined and communicate with the inner cavity of the cylindrical groove 33, so that the palmitic acidized oil in the inner cavity of the cylindrical groove 33 can be transported from the two flow grooves 34 to the filter component 2;

[0028] Next, a connecting shaft 35 is rotatably connected to the center of the front side wall of the inner cavity of the cylindrical groove 33. The connecting shaft 35 is fixedly connected to the output end of the motor 1 32. An L-shaped stopper 36 is fixed on the outer surface of the connecting shaft 35 and rotates in the inner cavity of the cylindrical groove 33. The L-shaped stopper 36 is in close contact with the annular side wall of the inner cavity of the cylindrical groove 33.

[0029] Among them, the L-shaped block 36 is adapted to the two flow grooves 34. In the initial state, the L-shaped block 36 will block the connection between the flow groove 34 on one side and the inner cavity of the cylindrical groove 33, so that the palmitic acid oil is transported from the other flow groove 34 to the inner cavity of the filter component 2, and then the motor 1 32 rotates, causing the L-shaped block 36 to rotate ninety degrees, blocking the other flow groove 34, and the palmitic acid oil is transported from the previously blocked flow groove 34 to the filter component 2, so that the palmitic acid oil is transported from the two flow grooves 34 to the inner cavity of the filter component 2 at intervals.

[0030] Further, if Figure 4 and Figure 5 As shown, the filter component 2 includes a filter box 20, which is fixedly connected to the lower end of the mounting block 31. The upper end of the filter box 20 is provided with two symmetrical feed ports 21. The two feed ports 21 correspond to two flow grooves 34 respectively. The two flow grooves 34 are respectively communicated with the inner cavities of the two feed ports 21 for conveying palmitic acid oil to the inner cavity of the filter box 20. A second motor 22 is fixed to the right end of the filter box 20.

[0031] Next, the left and right side walls of the inner cavity of the filter box 20 are connected to the bidirectional screw 23 for common rotation, and the bidirectional screw 23 is fixedly connected to the output end of the motor 22. The outer surface of the bidirectional screw 23 is provided with a movable plate 24 that is slidably connected to the front and rear side walls of the inner cavity of the filter box 20. The movable plate 24 is threadedly connected to the bidirectional screw 23. When the bidirectional screw 23 rotates, the movable plate 24 can reciprocate left and right. The initial state is located in the middle of the bidirectional screw 23, so that the two feed ports 21 are located on the left and right sides of the movable plate 24. Triangular blocks 25 are fixed on the lower sides of the left and right ends of the movable plate 24. A filter screen 26 adapted to the movable plate 24 is fixed between the left and right side walls of the filter box 20. The two triangular blocks 25 and the movable plate 24 are both located at the upper end of the filter screen 26, which can push the impurities filtered out of the filter screen 26 and then discharge them.

[0032] Further, if Figure 5 As shown, positioning tubes 27 are fixed to both ends of the filter box 20, and the inner cavities of the two positioning tubes 27 are slidably connected to slide rods 28. L-shaped blocks 29 are fixed to the ends of the two slide rods 28 that are away from each other. A spring is fixedly connected between the vertical parts of the positioning tube 27 and the L-shaped block 29 on the same side. The spring is in a compressed state in the initial state, which is used to maintain the position of the positioning tube 27 and the L-shaped block 29, so that the positioning tube 27 and the L-shaped block 29 remain stable. After being stretched, the positioning tube 27 can also be automatically reset.

[0033] Next, a blocking plate 290 is fixed to the ends of the two L-shaped blocks 29 that are close to each other. A slag outlet that matches the blocking plate 290 on the same side is opened at both the left and right ends of the filter box 20. The slag outlet is in a straight line with the upper end of the filter screen 26, so that impurities on the upper end of the filter screen 26 can be discharged from the slag outlet on both sides.

[0034] Furthermore, a filter screen 202 is provided on the lower side of the filter screen 1 26. The filter screen 202 is fixed between the left and right side walls of the inner cavity of the filter box 20, and is used for secondary filtration of the palmitic acid oil filtered by the filter screen 1 26 to avoid residual impurities. A triangular plate 201 is symmetrically fixed to the bottom wall of the inner cavity of the filter box 20. A discharge port 203 compatible with the wastewater treatment component 4 is opened in the middle of the bottom wall of the inner cavity of the filter box 20. The triangular plate 201 is inclined toward the middle of the inner cavity of the filter box 20, so that the filtered palmitic acid oil is gathered in the middle of the bottom wall of the inner cavity of the filter box 20, and then transported from the discharge port 203 to the biodiesel production component 1.

[0035] Further, if Figure 7As shown, the wastewater treatment component 4 includes an installation box 40, a treatment box 41 is fixed on the upper end of the installation box 40, a grille 42 is fixed in the inner cavity of the treatment box 41, and the grille 42 is used to filter impurities in the wastewater. A water pump 43 is fixed on the left side of the upper end of the installation box 40. The water pump 43 is adapted to the wastewater treatment component 4 and the treatment box 41. The water pump 43 is used to transport the wastewater generated by the biodiesel production component 1 to the inner cavity of the grille 42, and then it is filtered by the grille 42;

[0036] Among them, an anaerobic digestion component 44 and an aerobic treatment component 45 are fixed in the inner cavity of the installation box 40. The anaerobic digestion component 44 is used to degrade organic matter in the wastewater. An anaerobic reactor (such as an EGSB or IC reactor) is used to efficiently degrade organic matter in the wastewater, and at the same time, biogas such as methane is generated for energy recovery (refer to the palm oil processing plant wastewater treatment case); the aerobic treatment component 45 includes an SBR treatment system and a deep treatment system. Aerobic biological treatment processes such as SBR are used to further remove organic matter and pollutants such as nitrogen and phosphorus in the wastewater. Through deep treatment processes such as sand filtration, activated carbon filtration, and reverse osmosis membrane system, fine suspended matter, soluble organic matter and salt in the wastewater are removed to achieve standard discharge or reuse of wastewater.

[0037] It should be noted that the biodiesel production component 1, anaerobic digestion component 44, aerobic treatment component 45 and grille 42 in the present invention are all existing technologies, and their installation and control methods are also conventional designs, which will not be elaborated in detail in the present invention.

[0038] Working principle of this device: This device is an emission reduction device for palmitic acid oil treatment. It can not only remove impurities in palmitic acid oil to improve the quality of product raw materials, but also remove microorganisms and impurities in post-production wastewater, reduce pollutants in wastewater, and make the wastewater meet discharge standards;

[0039] First, the palmitic acid oil raw material is poured into the inner cavity of the feed pipe 30. The palmitic acid oil raw material in the inner cavity of the cylindrical groove 33 can flow into the two flow grooves 34. When the L-shaped stopper 36 is located on the upper side of the flow groove 34 on the left, the palmitic acid oil raw material flows from the flow groove 34 on the right to the inner cavity of the feed port 21 on the right, and then enters the inner cavity of the filter box 20. At this time, the movable plate 24 is located in the middle of the outer surface of the bidirectional screw 23. After a period of time, the palmitic acid oil raw material is no longer transported, the motor 22 is started, and the bidirectional screw 23 moves the movable plate 24 to the right, pushing the impurities filtered out of the right side of the upper end of the filter screen 26 to the right;

[0040] As the movable plate 24 moves to the right, the motor 1 32 rotates the connecting shaft 35, causing the filter 1 26 to be located above the flow groove 34 on the right side. The palmitic acid oil feedstock is again fed from the feed pipe 30. At this time, the palmitic acid oil feedstock is fed from the flow groove 34 and the feed port 21 on the left side into the inner cavity of the filter box 20, and falls on the upper end of the filter 1 26 on the left side of the movable plate 24 and is filtered.

[0041] Next, when the movable plate 24 moves from the right to the left and is about to approach the left feed port 21, the L-shaped stopper 36 rotates again to block the left flow groove 34, so that the palmitic acid oil is transported from the right flow groove 34. This reciprocating motion allows the device to continuously transport the palmitic acid oil raw material, thereby increasing the filtration speed of the palmitic acid oil and discharging impurities on the upper end of the filter screen 26, thereby preventing the filter screen 26 from being blocked during filtration.

[0042] like Figure 6 As shown, during the process of the movable plate 24 moving to discharge impurities, the movable plate 24 contacts the positioning tube 27 on one side, pushing the positioning tube 27, and the positioning tube 27 moves with the L-shaped block 29 on the same side. The L-shaped block 29 moves out of the slag outlet with the connected blocking plate 290. The movable plate 24 and the triangular block 25 discharge the impurities from the slag outlet, thus preventing the impurities from clogging the filter screen 26.

[0043] Next, the palmitic acid oil filtered in the filter component 2 is transported to the biodiesel production component 1 and converted into biodiesel. Then, the water pump 43 transports the wastewater generated in the biodiesel production component 1 to the inner cavity of the treatment box 41. After being filtered by the treatment box 41, it is transported to the inner cavity of the anaerobic digestion component 44 to degrade the organic matter in the wastewater. The wastewater is then transported to the aerobic treatment component 45. Through the SBR treatment system and the deep treatment system, the wastewater can meet the discharge standards.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
