Description

Technical Field

[0001] This utility model relates to the field of oil-gas separation technology, specifically a high-efficiency oil-gas separator for waste tire pyrolysis. Background Technology

[0002] Waste tire pyrolysis refers to an industrial technology that transforms the complex polymers (mainly natural rubber, synthetic rubber, carbon black, and a small amount of additives) in waste tires into recyclable products through thermochemical decomposition reactions in a closed, high-temperature environment (usually controlled at 400℃-600℃) without or without oxygen.

[0003] The existing high-efficiency oil-gas separation technology for waste tire pyrolysis refers to the technical system that, in the waste tire pyrolysis process, for the "oil-gas mixture" (containing liquid oil mist, non-condensable combustible gas, trace amounts of carbon black dust and moisture) produced by the pyrolysis reactor, achieves efficient multiphase separation of "oil-gas-solid-water" through physical separation methods (such as gravity sedimentation, cyclone separation, baffle interception, electrostatic adsorption, etc.) under specific temperature and pressure conditions.

[0004] However, existing oil-gas separators mostly rely on the single action of "gravity + cyclone", which results in poor separation effect and makes it difficult to separate solid impurities such as carbon black in the oil-gas mixture. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency oil-gas separator for waste tire pyrolysis, in order to solve the problem mentioned in the background art that existing oil-gas separators mostly rely on the single action of "gravity + cyclone", resulting in poor separation effect and difficulty in separating solid impurities such as carbon black in the oil-gas mixture.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency oil-gas separator for waste tire pyrolysis, comprising a separator, a filter cylinder, and a collection cylinder, wherein the filter cylinder is fixedly connected to the bottom of the separator, the collection cylinder is fixedly connected to the bottom of the filter cylinder, and an oil-gas separation device is provided inside the separator.

[0007] The oil-gas separation device includes an air pump, a guide block, a feed inlet, and a spiral guide frame. The air pump is fixedly installed above the separation tank, and the air inlet is connected to the inside of the separation tank. A through hole is opened on the outer surface of the separation tank. The guide block is fixedly connected to the through hole of the separation tank. The feed inlet is fixedly connected to the front of the guide block and connected to the oil and gas source. The spiral guide frame is fixedly connected to the back of the guide block and fixedly connected to the inner wall of the separation tank. A vent hole is opened on the side of the spiral guide frame away from the inner wall of the separation tank. Through holes are opened on the upper and lower surfaces of the spiral guide frame. By introducing an oil-gas mixture into the feed inlet, the mixture moves from bottom to top in the spiral guide frame. Oil droplets adhere to the inside of the spiral guide frame, gather together, and fall through the through holes. The non-condensable gas is drawn away by the air pump to achieve the purpose of oil-gas separation.

[0008] Preferably, a baffle plate is fixedly connected inside the spiral guide frame. The surface of the baffle plate has several through holes. The baffle plate cuts the large vortex and prevents the oil mist from being carried away by the airflow.

[0009] Preferably, an electrostatic generator is installed on the right side of the guide block. By utilizing the difference in charge between oil mist particles and non-condensable gases in the oil and gas mixture, the oil mist is agglomerated into large droplets and settles, thereby improving the oil-gas separation effect.

[0010] Preferably, the guide block has a threaded hole on its right side, and the guide block and the electrostatic generator are connected by bolt thread through the threaded hole, which facilitates the maintenance and replacement of the electrostatic generator and improves the convenience of the device.

[0011] Preferably, a filter frame is slidably connected inside the filter cylinder, a filter plate is fixedly connected inside the filter frame, a handle is fixedly connected to the front of the filter plate, a connecting pipe is fixedly connected to the bottom of the separation tank, a pressure plate is slidably connected to the outer surface of the connecting pipe, a cylinder is fixedly installed at the bottom of the separation tank, a telescopic pipe is fixedly connected to the bottom of the separation tank, the pressure plate is connected to the output end of the cylinder, and the bottom of the telescopic pipe is fixedly connected above the pressure plate. The pyrolysis oil falls onto the filter plate through the connecting pipe, and the cylinder drives the pressure plate to rise and fall, squeezing and accelerating the filtration of the pyrolysis oil. Pulling the handle allows the filter plate to be removed and the solid impurities on it to be cleaned.

[0012] Preferably, a cavity is formed at the bottom of the collection tank, and a stirring motor is fixedly installed inside the cavity. The output end of the stirring motor is connected to a shaft, and stirring blades are fixedly connected to the outer surface of the shaft. An exhaust pipe is fixedly connected to the outer surface of the collection tank, and a discharge pipe is fixedly connected to the outer surface of the collection tank below the exhaust pipe. The other end of the exhaust pipe is connected to an exhaust pump. The stirring motor drives the stirring blades to rotate and agitate the cracked oil to further remove the gas contained in the oil. The gas is extracted by the exhaust pump to prevent it from being re-mixed into the cracked oil.

[0013] Preferably, the outer shells of the separation tank, filter cylinder, and collection tank are configured with a double-layer structure and a vacuum layer in the middle. A heating block is installed inside the vacuum layer. The vacuum layer can reduce heat loss, and the heating block can maintain a stable temperature inside the separation tank, filter cylinder, and collection tank, which facilitates oil-gas separation.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This high-efficiency oil-gas separator for waste tire pyrolysis introduces an oil-gas mixture into the feed inlet. The mixture moves upward in a spiral guide frame, where oil droplets adhere to the inside of the spiral guide frame, gather together, and fall through the through-holes. The non-condensable gas is then pumped away by an air pump to achieve oil-gas separation. Baffles cut the large vortex to prevent oil mist from being carried away by the airflow. An electrostatic generator utilizes the difference in charge between oil mist particles and non-condensable gas to cause the oil mist to gather into large droplets and settle, thus improving the oil-gas separation effect.

[0016] 2. This high-efficiency oil-gas separator for waste tire pyrolysis allows pyrolysis oil to fall onto a filter plate via a connecting pipe. A cylinder drives a pressure plate to rise and fall, squeezing the pyrolysis oil to accelerate filtration. Pulling the handle removes the filter plate, allowing for the cleaning of solid impurities. A stirring motor drives the stirring blades to further remove gases from the pyrolysis oil. These gases are then pumped away to prevent re-mixing into the pyrolysis oil. The vacuum layer reduces heat loss, and a heating block maintains a stable temperature inside the separator, filter cylinder, and collection tank, facilitating oil-gas separation.

The spiral guide frame 203 is fixedly connected to the back of the guide block 201 and fixed to the inner wall of the separation tank 1. The spiral guide frame 203 has a vent hole on the side away from the inner wall of the separator tank 1. The upper and lower surfaces of the spiral guide frame 203 have through holes. A baffle 204 is fixedly connected inside the spiral guide frame 203. The surface of the baffle 204 has several through holes. An electrostatic generator 205 is installed on the right side of the guide block 201. A threaded hole is opened on the right side of the guide block 201. The guide block 201 and the electrostatic generator 205 are connected by bolts through the threaded hole.

[0025] In this embodiment, an oil-gas mixture is introduced into the feed inlet 202. The mixture moves from bottom to top in the spiral guide frame 203. Oil droplets adhere to the inside of the spiral guide frame 203, gather together, and fall through the through hole. The non-condensable gas is drawn away by the air pump 2 to achieve the purpose of oil-gas separation. The baffle 204 cuts the large eddy current to prevent oil mist from being carried away by the airflow. The electrostatic generator 205 can use the difference in charge between the oil mist particles and the non-condensable gas in the oil-gas mixture to make the oil mist gather into large droplets and settle, thereby improving the oil-gas separation effect.

[0029] In this embodiment, the pyrolysis oil falls onto the filter plate 301 through the connecting pipe 303. The cylinder 305 drives the pressure plate 304 to rise and fall, squeezing the pyrolysis oil to accelerate filtration. Pulling the handle 302 allows the filter plate 301 to be removed and the solid impurities on it to be cleaned. The stirring motor 4 drives the stirring blade 401 to rotate and stir the pyrolysis oil to further remove the gas contained in the oil. The gas is pumped away by the vacuum pump to prevent it from being mixed back into the pyrolysis oil. The vacuum layer can reduce heat loss. The heating block keeps the inside of the separation tank 1, the filter cylinder 101 and the collection tank 102 at a stable temperature, which facilitates oil-gas separation.

[0030] Working principle: By introducing an oil-gas mixture into the feed inlet 202, the mixture moves from bottom to top in the spiral guide frame 203. Oil droplets adhere to the inside of the spiral guide frame 203, gather together, and fall through the through hole. The non-condensable gas is drawn away by the air pump 2 to achieve the purpose of oil-gas separation. The baffle 204 cuts the large vortex to prevent oil mist from being carried away by the airflow. The electrostatic generator 205 can use the difference in charge between the oil mist particles and the non-condensable gas in the oil-gas to make the oil mist gather into large droplets and settle, thereby improving the oil-gas separation effect. The pyrolysis oil falls onto the filter plate 301 through the connecting pipe 303. The cylinder 305 drives the pressure plate 304 to rise and fall, squeezing the pyrolysis oil and accelerating filtration. Pulling the handle 302 removes the filter plate 301 to clean off solid impurities. The stirring motor 4 drives the stirring blades 401 to rotate and further remove gases from the oil. These gases are then removed by a vacuum pump to prevent re-mixing into the pyrolysis oil. The vacuum layer reduces heat loss, and the heating block maintains a stable temperature inside the separation tank 1, filter cylinder 101, and collection tank 102, facilitating oil-gas separation. The air pump 2 is a 2X-15A model, the electrostatic generator 205 is an ESD61000-2 model, the stirring motor 4 is a Y100L1-4 model, and the cylinder 305 is an SC63×50 model.
