Description

Technical Field

[0001] The present invention relates to the technical field of edible oil refining, and particularly relates to an edible oil continuous refining treatment device and method. Background Art

[0002] Traditional edible oil refining processes usually adopt decentralized equipment for step-by-step treatment. Each process depends on independent heat sources and material transfer devices, resulting in high energy consumption and process interruption.

Additional steam generators and wastewater treatment systems are required for processes such as water washing and deodorization. The equipment layout is loose and the thermal energy utilization rate is low. In addition, the transfer of oil between tanks mostly uses intermittent pumping, which easily causes problems such as process incoherence and oil oxidation.

[0035] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 shown, a continuous refining treatment device for edible oil includes a circular base 1, and a degumming tank 3, a deacidification tank 4, a water washing tank 5, a decolorization tank 6 and a deodorization tank 9 are annularly arranged on the top thereof in the refining order. It further includes:

[0036] A heat treatment tower 2 is arranged at the center of the top of the base 1. A first partition 21 is arranged inside the heat treatment tower 2 to divide the inside of the heat treatment tower 2 into a water storage chamber 25 and a combustion chamber 23 from top to bottom. The water storage chamber 25 is communicated with an external water supply device to continuously supply water into the water storage chamber 25. A hot water pipe 28 and a steam pipe 27 are also communicated with the heat treatment tower 2. Among them, one end of the hot water pipe 28 is communicated with the water storage chamber 25, and the other end is communicated with the water inlet of the water washing tank 5. One end of the steam pipe 27 is communicated with the top of the water storage chamber 25, and the other end is communicated with the air inlet of the deodorization tank 9;

[0037] An extrusion device 7 is arranged at the bottom of the decolorization tank 6 and is communicated with the discharging port of the decolorization tank 6. The mixed liquid of oil and activated clay in the decolorization tank 6

[0038] A second partition 22 is further arranged in the combustion chamber 23. The second partition 22 separates a regeneration chamber 24 between the combustion chamber 23 and the first partition 21. The feeding end of the regeneration chamber 24 is communicated with the extrusion device 7, and the discharging end is communicated with the decolorization tank 6 through a discharging pipe 26.

[0039] In this embodiment, when the edible oil continuous refining treatment equipment is in operation, the crude oil starts from the degumming tank 3 and sequentially enters the deacidification tank 4, the water washing tank 5, the decolorization tank 6 and the deodorization tank 9 to complete the refining process; the combustion chamber 23 of the heat treatment tower 2 generates high temperature through gas combustion, heats the water in the water storage chamber 25 to generate hot water and steam: the hot water is transported to the water washing tank 5 through the hot water pipe 28 for washing the oil-water mixture, and the steam provides the high-temperature steam required for the deodorization process for the deodorization tank 9 through the steam pipe 27; the oil and activated clay mixture in the decolorization tank 6 enters the bottom extrusion device 7, and after extrusion and dehydration, the decolorized oil and the water-containing clay are separated; the decolorized oil is transported to the deodorization tank 9, and the water-containing clay is sent into the regeneration chamber 24 beside the combustion chamber 23 through the feeding device, and is regenerated at high temperature using the waste heat of the combustion chamber 23. After removing moisture and adsorbed impurities, the regenerated clay returns to the decolorization tank 6 for recycling;

[0040] This equipment integrates the water storage chamber 25 and the regeneration chamber 24 through the combustion chamber 23 to realize multi-stage utilization of heat energy: the combustion chamber 23 directly heats the water storage chamber 25 to generate hot water and steam, and at the same time regenerates the clay through waste heat, reducing energy consumption; the cyclic regeneration of the activated clay reduces the cost of waste clay treatment and environmental pollution, and improves the resource utilization rate.

[0041] Preferably, the extrusion device 7 includes a blanking pipe 72 communicated with the bottom discharge port of the decolorization tank 6, the bottom of which is communicated with a horizontal extrusion pipe 71. A first auger 73 rotates in the extrusion pipe 71, and a first motor 74 for driving the first auger 73 to rotate is arranged at one end, and the other end is communicated with the feeding device for discharging the dehydrated clay; a drain hole is opened at the bottom of the extrusion pipe 71, and the drain hole is communicated with the deodorization tank 9 through a connecting pipe 8;

[0042] Along its feeding path, the inner diameter of the extrusion pipe 71 is tapered in a conical shape; the first auger 73 is adapted to the inner diameter of the extrusion pipe 71 and along its feeding path, the blade spacing is tapered.

[0043] The oil and activated clay mixture in the decolorization tank 6 enters the blanking pipe 72 through the bottom discharge port, and then falls into the horizontally arranged extrusion pipe 71; the first motor 74 drives the first auger 73 to rotate, pushing the mixture to move along the tapered inner cavity of the extrusion pipe 71 towards the feeding device; due to the tapered inner diameter of the extrusion pipe 71 and the synchronous taper of the blade spacing of the first auger 73, the mixture is subjected to an increasingly strong extrusion force during transportation, and the oil and water are squeezed and separated through the drain hole at the bottom of the extrusion pipe 71: the decolorized oil and water are discharged into the deodorization tank 9 through the drain hole for further treatment, while the dehydrated clay is pushed to the feeding device at the end of the first auger 73.

[0044] Preferably, the feeding device includes a feeding pipe 75, in which a second auger 76 rotates. A second motor for driving the second auger 76 to rotate is provided at the bottom of the feeding pipe 75. The top of the feeding pipe 75 communicates with the regeneration chamber 24;

[0045] After the dehydrated clay is discharged from the end of the extrusion pipe 71, it enters the feeding pipe 75. The second motor drives the second auger 76 in the feeding pipe 75 to rotate, pushing the clay to be conveyed upward along the feeding pipe 75, and finally entering the regeneration chamber 24 through the outlet at the top of the feeding pipe 75. In the regeneration chamber 24, the clay is regenerated at a high temperature using the waste heat of the combustion chamber 23, removing the adsorbed impurities and restoring its activity, and then being recycled back to the decolorization tank 6 to participate in the decolorization process.

[0046] Preferably, the second partition 22 is inclined and extends obliquely downward along its feeding direction; its inclined surface forms a clay sliding channel, and the second partition 22 serves as a heat-conducting medium to transfer the heat of the combustion chamber 23 to the regeneration chamber 24;

[0047] In the regeneration chamber 24, the water-containing clay discharged from the top of the feeding pipe 75 falls onto the inclined channel formed by the second partition 22. Since the second partition 22 is inclined downward along the feeding direction, the clay naturally slides down along the inclined surface under the action of gravity. At the same time, the high temperature of the combustion chamber 23 heats the clay through the heat conduction of the second partition 22. The clay is continuously heated during the sliding process, gradually removing the moisture and adsorbed impurities, and after regeneration, it returns to the decolorization tank 6 from the discharge end of the regeneration chamber 24 for recycling.

[0048] Preferably, the degumming tank 3 is the starting end of the edible oil refining process, and a feeding place for pouring crude oil is provided thereon; the deodorizing tank 9 is the end of the edible oil refining process, and a discharging place for discharging crude oil is provided thereon; the degumming tank 3, the deacidifying tank 4, the water washing tank 5, and the decolorizing tank 6 are connected end to end through a connecting pipe 8. Among them, the top of the deacidifying tank 4 is connected to the bottom of the degumming tank 3 through the connecting pipe 8, and the bottom of the decolorizing tank 6 is connected to the top of the deodorizing tank 9 through the connecting pipe 8;

[0049] The connecting pipe 8 includes a pump body 801 and a pipe body 802 whose inlet and outlet ends are connected to the pump body 801;

[0050] The crude oil is fed into the degumming tank 3 from the feeding point at the top. After degumming treatment, it is pumped by the connecting pipe 8 at the bottom of the degumming tank 3 to the deacidification tank 4 for deacidification; the deacidified oil continues to enter the water washing tank 5 for washing and the decolorization tank 6 for decolorization through the connecting pipe 8 in sequence, and finally is transported to the deodorization tank 9 to complete the deodorization treatment. The refined oil is discharged from the discharging point of the deodorization tank 9; the connecting pipe 8 between each tank body provides power through the pump body 801 to drive the oil to flow: the pipe body 802 of the pump body 801 is connected to the inlet and outlet of the adjacent tank body. The deacidification tank 4 receives the oil from the degumming tank 3 through the connecting pipe 8 at the top, and the decolorized oil is transported to the deodorization tank 9 through the connecting pipe 8 at the bottom of the decolorization tank 6, forming a continuous refining closed-loop process;

[0051] The external gas is transported to the combustion chamber 23 through the channel of the base 1. After the ignition device is started, the gas is ignited and continuously burns in the combustion chamber 23 to generate high temperature; the combustion heat directly heats the water in the water storage chamber 25 to generate hot water and steam, and at the same time transfers the waste heat to the regeneration chamber 24 through the second partition 22 for the high-temperature regeneration of activated clay. The base 1 serves as a transfer structure for gas transportation, ensuring the stable supply of gas to the combustion chamber 23 and supporting the heat supply requirements of the entire heat treatment tower 2.

[0052] Preferably, the combustion chamber 23 is connected to the base 1, the base 1 is connected to the external gas transportation device, and an ignition device is also provided in the combustion chamber 23.
