Description

Technical Field

[0001] This utility model belongs to the field of oil refining production technology, and specifically relates to a deodorizing oil refining production line that efficiently utilizes heat. Background Technology

[0002] Animal fats, as a natural resource rich in saturated and unsaturated fatty acids, can be widely used in cooking, baking, pharmaceuticals and biofuels after refining. The heat in the refining process of animal fats usually comes from jacket heating. Although this heating method achieves physical isolation between the heat source and flammable materials, reducing the risk of fire and explosion, it takes a long time to reach the target temperature due to its limited heat transfer area, which can easily affect the refining efficiency of the equipment.

[0003] In the process of refining animal fats from heat transfer oil, the heat transfer oil needs to be heated by burning fuel in a heat transfer oil boiler to provide a stable heat source for the refining pot. This process is accompanied by two main types of waste gases: first, a large amount of hot flue gas generated by the combustion of boiler fuel, which, if directly emitted, is not only a waste of energy but also causes thermal pollution to the local environment; second, the refining evaporation waste gas formed by the evaporation of moisture and volatile substances in the oil in the high-temperature heat transfer oil pot, which not only emits a foul odor but also pollutes the environment if directly emitted. Therefore, it is necessary to purify the waste gases generated during the animal fat refining process to prevent the refining evaporation waste gas from polluting the environment.

[0004] According to the existing technology announcement number CN 223255181 U, an environmentally friendly animal fat refining equipment is used. The device controls the guide ring through the drive component to move multiple stirring rods at the outer end to different positions to carry out stirring work, effectively stirring and turning the grease inside the processing pot. By setting up an extraction hood and filter elements, the flue gas generated by the processing pot is drawn into the filter box for filtration treatment.

[0005] A search revealed an oil refining furnace with the existing technology announcement number CN 221571104 U. This device uses a motor to control a rotating shaft to drive a stirring rod to mix petroleum feedstock and reactants after they have been filtered by a filter screen. At the same time, a heating tube is controlled to assist the petroleum feedstock in the reaction. A large amount of waste gas is generated during the heating of the petroleum feedstock and reactants. This waste gas is then adsorbed and purified by an activated carbon layer in the flue. A gas detector is then used to detect the waste gas after adsorption treatment. When the gas emission reaches the standard, the waste gas is discharged through the flue.

[0006] The adsorption materials used in the above two devices adsorb a large amount of oil and impurities, requiring frequent shutdowns for replacement, resulting in high operation and maintenance costs. Furthermore, the removed adsorption materials still need to be treated as hazardous waste for special harmless treatment in order to achieve recycling or environmentally friendly discharge.

[0007] Therefore, there is a need for a heat-efficient deodorizing oil refining production line that can directly treat the waste gas generated during the oil refining process in a harmless manner, effectively solving the environmental protection and odor problems in the oil refining process, while recovering and utilizing waste heat to improve the oil refining efficiency of the production line. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency heat-utilizing deodorizing oil refining production line. This invention mixes the oil refining evaporation waste gas with the boiler flue gas to form a mixed pyrolysis gas, which is then transported into a thermal oil boiler for high-temperature pyrolysis. This not only thoroughly decomposes pollutants and odors in the high-temperature environment of the thermal oil boiler, achieving harmless treatment of waste gas and effectively solving the environmental protection and odor problems in the oil refining process, but also allows the mixed pyrolysis gas after high-temperature pyrolysis to be transported into a preheating pot and oil tank for preheating and heat preservation.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A high-efficiency heat-utilizing, flavor-neutralizing oil refining production line includes a thermal oil boiler, a dust collector, a preheater, a gas mixing chamber, an oil tank, a preheating pot, a refining pot, a feeder, a slag pressing and briquetting machine, a slag discharge conveyor belt, a fuel feeder, a thermal oil storage tank, a screw pump, and a hot oil pump III. The fuel feeder is fixedly connected to one side of the thermal oil boiler. The dust collector and preheater are arranged side-by-side between the thermal oil boiler and the gas mixing chamber. The oil tank is located on one side of the gas mixing chamber, and the preheating pot is located between the oil tank and the refining pot. One side of the feeder is fixedly connected to the ground, and the other end is fixedly connected to the preheating pot and the refining pot. The slag pressing and briquetting machine is fixedly connected to one end of the slag discharge conveyor belt, and the other end of the slag discharge conveyor belt is connected to the refining pot. The thermal oil storage tank is located on one side of the thermal oil boiler. The hot oil pump III is connected to the preheating pot, the refining pot, and the thermal oil storage tank through pipelines, and the screw pump is connected to the preheating pot and the refining pot through pipelines.

[0011] The preheating pot is provided with a feed inlet I at the top, and a liquid inlet I, a liquid outlet I, and a discharge outlet on one side. One end of the pipe I is fixedly connected to one side of the preheating pot. The oil refining pot is provided with a feed inlet II at the top, and a slag outlet, a liquid outlet II, a feed inlet III, and a liquid inlet II on one side. The liquid inlet of the hot oil pump II is connected to an oil outlet on the other side of the oil refining pot through a pipe. The liquid outlet of the hot oil pump II is fixedly connected to an oil tank through a pipe.

[0012] One side of the thermal oil boiler is connected to the air inlet of fan I via a pipe, and the air outlet of fan I is fixedly connected to the other side of the preheating pot via a pipe; one end of the oil tank is connected to the liquid inlet of hot oil pump I via a pipe, the air outlet of fan V is connected to the exhaust gas treatment box via a pipe, and the other end of pipe I passes through the bottom of the oil tank and is connected to the air inlet of fan V.

[0013] One side of the dust collector is fixedly connected to the top of the thermal oil boiler via a pipe, and the other side is connected to the air inlet of fan II via a pipe running from top to bottom through the preheater. Fan III is fixedly connected to one side of the preheater, and the bottom of the preheater is fixedly connected to the bottom of the thermal oil boiler via a pipe. One end of the gas mixing box is fixedly connected to the air outlets of fan II and fan IV via two sets of pipes, and the other end is fixedly connected to the thermal oil boiler via a connecting pipe. The air inlet of fan IV is fixedly connected to the exhaust port located at the top of the preheating pot and the refining pot via a T-shaped pipe.

[0014] The feeding machine is fixedly connected to feed inlet I and feed inlet II via two sets of screw conveyors on one side, and electric knife gate valves are provided on feed inlet I and feed inlet II; one end of the slag discharge transmission belt is fixedly connected to the connecting pipe on the slag discharge port, and the other end is connected to the slag pressing and cake forming machine, and an electric knife gate valve is provided on the slag discharge port.

[0015] The hot oil pump III is located between the dust collector and the thermal oil boiler. The pipe connected to the inlet of the hot oil pump III is connected to the thermal oil storage tank and the drain outlet I and drain outlet II respectively through three sets of branch pipes. The delivery pipe connected to the outlet of the hot oil pump III is connected to the thermal oil storage tank and the inlet I and inlet II respectively through three sets of branch pipes. The feed inlet of the screw pump is fixedly connected to the discharge outlet through a pipe, and the discharge outlet of the screw pump is fixedly connected to the feed inlet III through a pipe.

[0016] When fuel enters the thermal oil boiler through the fuel feeder for combustion, the resulting boiler flue gas enters the dust collector through a pipeline for dust removal. Subsequently, the boiler flue gas passes through the preheater and fan II and enters the gas mixing box. At the same time, fan III draws in clean air from the outside and sends it into the preheater, where it is preheated with the help of the boiler flue gas. The preheated clean air then enters the thermal oil boiler to provide oxygen for the combustion of fuel in the boiler.

[0017] The heat transfer oil is controlled by hot oil pump III to enter the heat transfer oil boiler for heating. Then, the heat transfer oil enters the preheating pot and the oil refining pot between the inner and outer walls through the branch pipe on the delivery pipe, thereby heating the preheating pot and the oil refining pot. Then, the heat transfer oil enters the hot oil pump III again through the pipe connected to the liquid inlet of hot oil pump III, thus realizing the circulation of heat transfer oil. At the same time, the heat transfer oil storage tank plays the role of replenishing the flowing heat transfer oil and preventing the heat transfer oil from overflowing due to thermal expansion.

[0018] Fan IV extracts the evaporation waste gas generated during the oil refining process in the preheating pot and refining pot, directing it into a gas mixing box. The evaporation waste gas mixes with boiler flue gas in the gas mixing box, forming a mixed cracked gas that passes through a connecting pipe into a thermal oil boiler for heating. The mixed cracked gas is then subjected to thermal cracking within the thermal oil boiler, removing pollutants and odors. Simultaneously, fan I draws the mixed cracked gas from the thermal oil boiler between the inner and outer walls of the preheating pot, preheating the raw materials within. Then, fan V draws the mixed cracked gas from the preheating pot into a tail gas treatment box through pipe I. After purification treatment in the tail gas treatment box, the gas is discharged. As the mixed cracked gas passes through pipe I, it can insulate against the finished oil in the oil tank, preventing the finished oil from cooling and solidifying.

[0019] The material in the preheating pot is transported into the oil refining pot by a screw pump for further refining. At the same time, hot oil pump II draws out the finished oil produced in the oil refining pot and sends it into the oil tank for storage through the conveying pipe.

[0020] The advantages of this utility model compared with the prior art are as follows:

[0021] 1) By controlling the heat generated during the operation of the thermal oil boiler, the heat generated during the operation of the thermal oil boiler is used to heat the preheating pot and the oil refining pot, realizing the efficient utilization of energy in a cascade manner; at the same time, the boiler flue gas generated during the operation of the thermal oil boiler is controlled to preheat the combustion air, which not only ensures the normal combustion of fuel in the thermal oil boiler, but also effectively prevents cold air from entering the thermal oil boiler and affecting the rate of temperature rise in the thermal oil boiler, thereby improving the thermal efficiency of the entire system and reducing energy consumption.

[0022] 2) The mixed pyrolysis gas formed by mixing the oil refining evaporation waste gas and the boiler flue gas is transported into the thermal oil boiler for high-temperature pyrolysis. This not only completely decomposes pollutants and odors in the high-temperature environment of the thermal oil boiler, achieving harmless treatment of waste gas and effectively solving the environmental protection and odor problems in the oil refining process, but also allows the mixed pyrolysis gas after high-temperature pyrolysis to be transported into the preheating pot and oil tank for preheating and heat preservation.

[0036] Combined with appendix Figure 3 and attached Figure 4The route shown in ① represents the flow of boiler flue gas generated when fuel enters the thermal oil boiler 1 through the fuel feeder 11 for combustion. The boiler flue gas enters the dust collector 2 for dust removal, and then passes through the preheater 3 and the fan II 201 into the gas mixing box 4. At the same time, the fan III 301 draws in clean air from the outside and makes it flow along the route shown in ②. The clean air from the outside enters the preheater 3 and is preheated with the help of the boiler flue gas. After being preheated, the clean air from the outside enters the thermal oil boiler 1 to provide oxygen for the combustion of fuel in the thermal oil boiler 1.

[0040] A high-efficiency heat-utilizing deodorizing oil refining production line operates as follows:

[0041] Raw materials are fed into the preheating pot 6 and the refining pot 7 via the feeder 8. Then, the fuel feeder 11 feeds fuel into the thermal oil boiler 1 for combustion. The boiler flue gas generated during fuel combustion is dedusted in the dust collector 2 and then enters the preheater 3 to heat the outside clean air drawn into the preheater 3 by the blower Ⅲ301. The heated outside clean air then enters the thermal oil boiler 1, while the boiler flue gas enters the gas mixing box 4. The hot oil pump Ⅲ14 controls the thermal oil to circulate and heat the preheating pot 6 and the refining pot 7 along route ③. Then, the screw... The rod pump 13 transports the material in the preheating pot 6 into the refining pot 7 for further refining. Finally, the finished oil produced by the refining pot 7 enters the oil tank 5 for storage via route 6. The oil refining evaporation waste gas generated by the preheating pot 6 and the refining pot 7 during the refining of raw materials enters the gas mixing box 4 along route 4 and mixes with the boiler flue gas to form mixed cracked gas. Then, the mixed cracked gas enters the heat transfer oil boiler 1 through the connecting pipe 402 for heating and cracking. The cracked mixed cracked gas then heats the preheating pot 6 along route 5 and keeps the oil tank 5 warm.
