Description

Technical Field

[0001] The utility model belongs to the technical field of biodiesel production, and particularly relates to a biodiesel enzymatic reaction system. Background Art

[0002] Waste cooking oil (Waste cooking oil) refers to various low-quality oils commonly found in daily life. Its main component is triglycerides, which are widely available and relatively abundant. It is a type of raw material for biodiesel production. Using waste cooking oil as a raw material to produce biodiesel can create economic benefits while avoiding environmental pollution and resource waste caused by direct discharge of waste cooking oil. The principle of using waste cooking oil to produce biodiesel is as follows: after pre-treating the waste cooking oil to remove impurities, the main components, triglycerides, and methanol, in the waste cooking oil undergo an ester exchange reaction under the action of a catalyst to produce fatty acid methyl esters (biodiesel) and glycerol. Currently, the biodiesel production process often uses acid catalysts, such as sulfuric acid and phosphoric acid. However, these catalysts have the disadvantage of generating acidic wastewater during the biodiesel production process. This acidic wastewater cannot be discharged directly and must be deacidified before being discharged, thus reducing the economic benefits of the biodiesel product.

[0003] Enzymatic catalysis can overcome the technical drawbacks of acid catalysts. However, existing enzymatic catalysis technologies suffer from low conversion rates to waste cooking oil because the lipase used is susceptible to methanol, which irreversibly inactivates it. Furthermore, due to the instability of lipase activity, enzymatic catalysis requires a long time, resulting in low biodiesel production efficiency and yield within a limited timeframe.

DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It is apparent that the embodiments described herein are merely a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; of course, they can also refer to mechanical connections or electrical connections; in addition, they can also refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] Example 1

[0028] like Figure 1 As shown, the utility model provides a biodiesel enzymatic reaction system, which includes a raw material premixing mechanism, a methanol conveying mechanism connected to an external methanol source and connected to the raw material premixing mechanism, an enzyme catalytic mechanism connected from the raw material premixing mechanism and the methanol conveying mechanism respectively, a sedimentation and separation mechanism connected from the enzyme catalytic mechanism and connected to the raw material premixing mechanism, and a methanol waste gas conveying mechanism connected from the raw material premixing mechanism, the enzyme catalytic mechanism and the sedimentation and separation mechanism respectively.

[0029] The utility model has a simple structure, a scientific and reasonable design, and is easy to use. The utility model connects multiple reaction tanks such as enzyme tank one, enzyme tank two, and enzyme tank three in series for use. On the one hand, the amount of raw materials used at a single time is increased by adding the number of reaction tanks, which can improve the biodiesel yield. On the other hand, the reaction raw materials are further reacted in each reaction tank in sequence according to the sequence of the reaction tanks being connected in series, which ensures that the reaction raw materials react fully and improves the conversion rate of the reaction raw materials. At the same time, in the process of the reaction raw materials successively changing their positions in the sequence of the reaction tanks such as enzyme tank one, enzyme tank two, and enzyme tank three being connected in series for further reaction, the methanol delivery mechanism adds a portion of methanol to each reaction tank. In this way, while ensuring that the ester exchange reaction proceeds normally, it avoids the inactivation of lipase due to excessive methanol in the raw materials at one time, thereby ensuring the stability of lipase activity to a certain extent and improving the biodiesel production efficiency.

[0030] Example 2

[0031] like Figure 1 As shown, the utility model provides a biodiesel enzymatic reaction system, which includes a raw material premixing mechanism, a methanol conveying mechanism connected to an external methanol source and connected to the raw material premixing mechanism, an enzyme catalytic mechanism connected from the raw material premixing mechanism and the methanol conveying mechanism respectively, a sedimentation and separation mechanism connected from the enzyme catalytic mechanism and connected to the raw material premixing mechanism, and a methanol waste gas conveying mechanism connected from the raw material premixing mechanism, the enzyme catalytic mechanism and the sedimentation and separation mechanism respectively.

[0032] The enzyme catalysis mechanism includes an enzyme tank reaction mechanism connected to the methanol delivery mechanism and the raw material premixing mechanism respectively, a cold water input mechanism connected to an external cold water source and connected to the enzyme tank reaction mechanism, and a hot water output mechanism connected to the enzyme tank reaction mechanism; the enzyme tank reaction mechanism and the hot water output mechanism are respectively connected to the sedimentation separation mechanism.

[0033] In the present embodiment 2, the raw material in the raw material premixing mechanism is mainly waste cooking oil, and the enzyme tank reaction mechanism is equipped with lipase. Waste cooking oil and methanol undergo ester exchange reaction in the enzyme tank reaction mechanism through lipase catalysis to generate fatty acid methyl esters (biodiesel) and glycerol. The methanol delivery mechanism is used to supplement methanol in the enzyme tank reaction mechanism. While ensuring that the ester exchange reaction is carried out normally, it avoids the disposable excessive methanol in the reaction raw materials and causes lipase inactivation, ensures that the lipase activity is stable to a certain extent, and can improve biodiesel production efficiency. Wherein, the sedimentation separation mechanism is used to separate the biodiesel generated in the enzyme tank reaction mechanism and transport it to the next step for further refining. The methanol waste gas delivery mechanism is used to transport the methanol waste gas generated in the biodiesel production process to an external methanol recovery mechanism.

[0034] In this embodiment 2, the activity of lipase is easily affected by temperature. To ensure the activity of lipase, the enzyme tank reaction mechanism can generate heat by itself to increase the temperature. To avoid the temperature of the enzyme tank reaction mechanism being too high, the cold water input mechanism provides cooling water to cool the enzyme tank reaction mechanism. The cooling of the cooling water and the self-heating of the enzyme tank reaction mechanism interact with each other to achieve the purpose of adjusting the temperature of the enzyme tank reaction mechanism, so that the temperature of the enzyme tank reaction mechanism is appropriate and the efficiency of biodiesel production is improved.

[0035] After the cooling water cools the enzyme tank reaction mechanism, it absorbs heat and becomes hot water. Under the action of the hot water output mechanism, part of the hot water is transported to the sedimentation separation mechanism to absorb and dissolve the glycerol generated by the ester exchange reaction, so that the sedimentation separation mechanism can separate biodiesel.

[0036] Example 3

[0037] like Figure 1 As shown, the utility model provides a biodiesel enzymatic reaction system, which includes a raw material premixing mechanism, a methanol conveying mechanism connected to an external methanol source and connected to the raw material premixing mechanism, an enzyme catalytic mechanism connected from the raw material premixing mechanism and the methanol conveying mechanism respectively, a sedimentation and separation mechanism connected from the enzyme catalytic mechanism and connected to the raw material premixing mechanism, and a methanol waste gas conveying mechanism connected from the raw material premixing mechanism, the enzyme catalytic mechanism and the sedimentation and separation mechanism respectively.

[0038] The enzyme catalysis mechanism includes an enzyme tank reaction mechanism connected to the methanol delivery mechanism and the raw material premixing mechanism respectively, a cold water input mechanism connected to an external cold water source and connected to the enzyme tank reaction mechanism, and a hot water output mechanism connected to the enzyme tank reaction mechanism; the enzyme tank reaction mechanism and the hot water output mechanism are respectively connected to the sedimentation separation mechanism.

[0039] The enzyme tank reaction mechanism includes enzyme tank 1 connected from the raw material premixing mechanism, enzyme tank 2 connected from enzyme tank 1, enzyme tank 3 connected from enzyme tank 2, enzyme tank 4 connected from enzyme tank 3, enzyme tank 5 connected from enzyme tank 4 and the raw material premixing mechanism, enzyme tank 6 connected from enzyme tank 5, and enzyme tank 7 connected from enzyme tank 6. Enzyme tank 7 is connected to the sedimentation separation mechanism.

[0040] In this embodiment 3, enzyme tank 1, enzyme tank 2, enzyme tank 3, enzyme tank 4, enzyme tank 5, enzyme tank 6, and enzyme tank 7 are all equipped with lipase, the outer walls are all provided with jackets for heating the tank bodies, and cooling coils are all provided inside the tank bodies. In order to prevent the temperature of enzyme tank 1, enzyme tank 2, enzyme tank 3, enzyme tank 4, enzyme tank 5, enzyme tank 6, and enzyme tank 7 from being too high, a cold water input mechanism transports cooling water to the cooling coils to cool enzyme tank 1, enzyme tank 2, enzyme tank 3, enzyme tank 4, enzyme tank 5, enzyme tank 6, and enzyme tank 7. The heating jackets interact with the cold water in the cooling coils in pairs, so that the temperature of enzyme tank 1, enzyme tank 2, enzyme tank 3, enzyme tank 4, enzyme tank 5, enzyme tank 6, and enzyme tank 7 is appropriate, thereby ensuring the activity of lipase.

[0041] The mixed raw materials from the raw material premixing mechanism react further in enzyme tanks 1, 2, 3, and 4, in the order of enzyme tanks 1, 2, 3, and 4, respectively. After further reaction in enzyme tank 4, the mixed raw materials are substantially complete. The mixture in enzyme tank 4 can be directly passed to the sedimentation separation mechanism for biodiesel separation or further passed to enzyme tank 5, 5, for further reaction. The raw material premixing mechanism replenishes raw materials in enzyme tank 5, 5, 6, and 7, respectively, in the order of enzyme tanks 5, 6, and 7, respectively. After the reaction in enzyme tank 7 is complete, the mixture in enzyme tank 7 is passed to the sedimentation separation mechanism for biodiesel separation. The biodiesel separated by the sedimentation separation mechanism is fed into the next process for further refining, while the separated triglycerides, glycerin, and water are fed into the raw material premixing mechanism for triglyceride recovery.

[0042] During the process in which the mixed raw materials react in enzyme tank 1 1, enzyme tank 2 2, enzyme tank 3 3 and enzyme tank 4 4, and in enzyme tank 5 5, enzyme tank 6 6 and enzyme tank 7 7 in series order, the methanol conveyor adds methanol components to enzyme tank 1 1, enzyme tank 2 2, enzyme tank 3 3, enzyme tank 4 4, enzyme tank 5 5, enzyme tank 6 6 and enzyme tank 7 7, which can avoid excessive methanol in the mixed raw materials at one time and affect the activity of lipase.

[0046] When the mixed raw material in enzyme tank 1 exceeds the capacity, it overflows into enzyme tank 2 2 through overflow pipe 1 94. When the mixed raw material consumes enough methanol in enzyme tank 1 and methanol needs to be added to the mixed raw material, the enzyme tank 1 is pumped out by flow pump 1 96 and transferred to enzyme tank 2 2 through flow pipe 1 95. Methanol is added to enzyme tank 2 2, so that the mixed raw material further reacts in enzyme tank 2 2, while new mixed raw material continues to be introduced into enzyme tank 1.

[0047] Similarly, when the amount of raw materials in enzyme tank 2 exceeds the limit, the raw materials overflow into enzyme tank 3 through overflow pipe 2 97 . After the reaction of the raw materials in enzyme tank 2 is completed, the raw materials are transferred to enzyme tank 3 3 through flow pump 2 99 and flow pipe 2 98 . After methanol is added to enzyme tank 3 3 , the raw materials further react in enzyme tank 3 3 , while enzyme tank 2 2 continues to receive the raw materials transferred from enzyme tank 1 .

[0048] The principle of converting raw materials between enzyme tank three 3 and enzyme tank four 4, enzyme tank five 5 and enzyme tank six 6, enzyme tank six 6 and enzyme tank seven 7 is similar to the principle of converting raw materials between enzyme tank one 1 and enzyme tank two 2, and will not be repeated here.

[0049] When the raw materials are transferred between enzyme tank 24 4 and enzyme tank 5 5 for further reaction, the manual valve 107 on the delivery pipe 5 106 is opened, and the delivery pump 5 105 is turned on and the delivery pump 4 104 is turned off. The delivery pump 5 105 is used to extract the mixture in enzyme tank 24 4 and transport it to enzyme tank 5 5 through the delivery pipe 5 106.

[0050] When the mixture in the enzyme tank 44 is passed into the sedimentation separation mechanism, the flow pump 4 104 is turned on, the flow pump 5 105 and the manual valve 107 are closed; and the mixture is passed into the sedimentation separation mechanism using the flow pump 4 104 and the flow pipe 4 103.
