Description

Technical Field

[0001] The utility model relates to the technical field of waste oil pyrolysis devices, and particularly relates to a waste oil pyrolysis device. Background Art

[0002] Pyrolysis is a reaction process in which substances decompose when heated. Many inorganic and organic substances will undergo decomposition reactions when heated to a certain extent.

[0003] After long-term use, the internal of the engine oil contains more impurities, and this engine oil cannot be recycled under normal conditions. In order to avoid waste of resources, pyrolysis is usually used to recycle waste oil. The pyrolysis process is to pour the waste oil into a pyrolysis furnace for heating. After the heated engine oil is vaporized, it is transported to a condenser, and the engine oil is liquefied again through the condensation method. After the liquefied engine oil passes through processes such as filtration, it is recycled. When the traditional condenser is used, only by introducing a coolant, the vaporized engine oil exchanges heat with the coolant when being transported through the pipeline to achieve the effect of condensation and liquefaction;

[0004] The above method only condenses the vaporized engine oil by using the heat exchange of the coolant. In actual use, due to the relatively fast air flow velocity, the heat exchange time through the condensation pipe is limited. Under the condition that the air flow rate is relatively constant, among the air flow passing through the condensation pipe, the air flow in the outer layer has sufficient time to condense, while the air flow in the central position lacks sufficient time to condense, that is, a single condenser cannot achieve the effect of complete condensation, resulting in insufficient liquefaction efficiency of the engine oil. If multiple condensers are set, the cost is relatively high. Therefore, a waste oil pyrolysis device is proposed to solve the above problems. Summary of the Utility Model

[0005] Based on the above description, the utility model provides a waste oil pyrolysis device to solve the problem of insufficient liquefaction efficiency of the existing condenser for engine oil.

[0006] The technical solution for the utility model to solve the above technical problems is as follows: A waste oil pyrolysis device, comprising: a condenser, the condenser includes a condenser housing, side covers, condensation pipes and a transfer box. The side covers are arranged at both ends of the condenser housing and include a cover body, a fan housing and a filter plate. The condensation pipes are arranged inside the condenser housing and include a delivery pipe, a semi-circular box and a partition plate. The transfer box is arranged below the condenser housing and is communicated with the semi-circular box. The pyrolysis furnace is communicated with the side cover through a gas delivery pipe.

[0007] On the basis of the above technical solution, the utility model can be further improved as follows.

[0008] Further, the condenser housing includes a main housing, and a liquid outlet and a liquid inlet are respectively arranged on the upper and lower sides of the outer surface of the main housing.

[0009] Further, the cover body is connected to the main housing by screws and nuts and is in communication with the main housing.

[0010] Further, an air inlet is arranged on the upper surface of the cover body, and the air inlet is in communication with both the cover body and the gas transmission pipeline.

[0011] Further, a mounting seat is arranged on one side of the cover body away from the condenser housing, and the mounting seat is in communication with the cover body.

[0012] Further, a fan housing is arranged inside the mounting seat, a fan is arranged inside the fan housing, and a filter plate is arranged at one end of the fan housing.

[0013] Further, the condensation pipeline includes a delivery pipe, the delivery pipe is arranged inside the condenser housing, a semi-circular box is arranged between the delivery pipes, and a partition plate communicating with the semi-circular box is arranged between the delivery pipes.

[0014] Further, the semi-circular box is a semi-circular box body, the partition plates are respectively in communication with the two semi-circular boxes, and the two semi-circular boxes are arranged in a staggered manner.

[0015] Further, the transfer box includes a main box body, and a discharge pipe is arranged on the outer surface of the main box body.

[0016] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0017] 1. By setting components such as the condenser housing, the side cover, and the condensation pipeline, and through the cooperation relationship between the delivery pipe and the semi-circular box, after the pyrolysis furnace heats the waste oil to generate gas, the gas enters the inside of the delivery pipe through the gas transmission pipeline and the side cover and is transported to the semi-circular box. In this process, the gases at both ends of the semi-circular box collide with each other, and then the gaseous oil collides with each other after preliminary condensation, so as to extend the heat exchange time;

[0018] 2. By setting the fan, the effect of introducing external cold air into the condenser is achieved, so that the gaseous oil exchanges heat with the external cold air, and the condensation effect is achieved. The condensed gaseous oil turns into small droplets, that is, mist-like oil, and the mist-like oil is more likely to form larger droplets after collision, which is convenient for subsequent collection.

[0030] Please refer toFigures 1-4 , the condenser housing 1 includes a main housing 11. On the upper and lower sides of the outer surface of the main housing 11, a liquid outlet 13 and a liquid inlet 12 are respectively provided. The cover body 21 is connected to the main housing 11 by screws and nuts and is in communication with the main housing 11;

[0031] Side covers 2 are provided at both ends of the condenser housing 1 and include a cover body 21, a fan housing 24, and a filter plate 26. The cover body 21 is connected to the main housing 11 by screws and nuts and is in communication with the main housing 11. An air inlet 22 is provided on the upper surface of the cover body 21, and the air inlet 22 is in communication with both the cover body 21 and the gas transmission pipeline 4 at the same time. On one side of the cover body 21 away from the condenser housing 1, a mounting seat 23 is provided. The mounting seat 23 is in communication with the cover body 21. A fan housing 24 is provided inside the mounting seat 23, a fan 25 is provided inside the fan housing 24, and a filter plate 26 is provided at one end of the fan housing 24;

[0032] The pyrolysis furnace 3 is in communication with the side cover 2 through a gas transmission pipeline 4;

[0033] Based on the above, the side cover 2 and the condenser housing 1 are connected to each other by screws and nuts. When the fan 25 is powered on, it can suck external air into the inside of the side cover 2 and introduce it into the inside of the condenser housing 1. The pyrolysis furnace 3 pyrolyzes waste mechanisms to generate gas, and the gas is transmitted to the inside of the condenser through the gas transmission pipeline 4.

[0034] As Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the condensation pipeline 5 is provided inside the condenser housing 1 and includes a delivery pipe 51, a semi-circular box 52, and a partition plate 53;

[0035] The condensation pipeline 5 includes a delivery pipe 51. The delivery pipe 51 is provided inside the condenser housing 1. The semi-circular box 52 is provided between the delivery pipes 51. A partition plate 53 communicating with the semi-circular box 52 is provided between the delivery pipes 51. The semi-circular box 52 is a semi-circular box body. The partition plate 53 is in communication with both of the two semi-circular boxes 52, and the two semi-circular boxes 52 are arranged in a staggered manner;

[0036] The transfer box 6 is provided below the condenser housing 1 and is in communication with the semi-circular box 52. The transfer box 6 includes a main box body 61, and a discharge pipe 62 is provided on the outer surface of the main box body 61;

[0037] Based on the above, the setting of the condenser 5 enables gaseous engine oil to enter the semi-circular box 52 from two directions. During the process of entry, since the gas flow discharged from the pyrolysis furnace 3 is relatively constant, the density of gaseous engine oil in this gas flow is relatively constant. When this gas flow is split into two gas flows and enters the delivery pipe 51, due to the fixed diameter of the delivery pipe 51, the density of gaseous engine oil in the split gas flow is halved. After the gaseous engine oil with halved density enters the delivery pipe 51, it can more easily exchange heat with the coolant for condensation. After the gas flow enters the interior of the semi-circular box 52, the two gas flows collide with each other, which not only causes small droplets to gather into large droplets and fall down, but also reduces the flow velocity of the gas flow, making the discharge velocity of the gas flow slower, that is, it prolongs the heat exchange time of the gas flow in the semi-circular box 52.

[0038] When this embodiment is actually used, the waste engine oil is heated and pyrolyzed by the pyrolysis furnace 3, and the pyrolyzed engine oil flows into the interior of the side cover 2 in a gaseous form. At the same time, the blower 25 is powered on to work, sucking external air into the interior of the side cover 2;

[0039] The gas flow enters the interior of the delivery pipe 51 after passing through the side cover 2. During this process, the coolant is introduced into the interior of the condenser housing 1 from the liquid inlet 12 to provide a liquid cooling environment for the condensation pipeline 5. When the gas flow enters from both ends of the delivery pipe 51, since the same gas flow is split into two, the density of gaseous engine oil in the gas flow decreases, thereby enabling the gas flow to exchange heat more fully and avoiding the situation where the condensation effects of the inner and outer layers of gaseous oil are different due to a larger density. Moreover, the gas flow sucked by the blower will further reduce the density of gaseous oil in the gas flow, and the introduced air temperature is lower than the temperature of the gaseous oil, which can play a cooling effect during the transportation process;

[0040] When the gas flow enters the semi-circular box 52, the flow velocity is greatly reduced after the two gas flows collide with each other, making the discharge velocity of the gas flow greatly reduced. After the flow velocity is reduced, the gas flow stays in the semi-circular box 52 for a longer time, thereby prolonging the condensation time of the gas flow;

[0041] This pyrolysis device enables the pyrolyzed gaseous engine oil to be more fully condensed into liquid engine oil by setting a unique condenser. Compared with traditional pyrolysis devices, the efficiency of condensing out oil is better.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
