Description

Technical Field

[0001] The utility model belongs to the field of environmental protection, relates to oil sludge treatment, and specifically relates to a microporous pyrolysis type oil sludge treatment device. Background Art

[0002] Oil sludge treatment is a crucial environmental technology. It primarily targets the harmless, reduced, and resource-efficient treatment of oil sludge, which contains various organic substances and impurities, generated during the extraction and processing of oil and natural gas. This sludge contains high concentrations of organic solvents, heavy metals, and other hazardous substances. Improper treatment can cause severe contamination of soil and groundwater, impacting the ecological environment and human health. Traditional methods for treating oil sludge include solidification / stabilization, pyrolysis, and biodegradation.

[0003] Solidification / stabilization technology: Mixing oil sludge with inorganic materials such as cement and lime, chemically encapsulates harmful substances, reducing their release and rendering them harmless. However, this method requires a large area and, in the long term, may still cause the migration of harmful substances.

[0004] Biodegradation technology: uses microorganisms to decompose organic matter in oil sludge, achieving the goal of reducing its volume and rendering it harmless. This method has low energy consumption and minimal environmental impact, but the treatment process takes a long time and is not suitable for emergency treatment.

[0005] Pyrolysis technology: By heating oil sludge, the organic matter in it is decomposed, thereby achieving the goal of reducing waste and recycling it. Existing pyrolysis methods mainly use high-temperature steam to heat oil sludge. The steam decomposes the organic matter in the sludge and converts it into water-soluble substances and gases. This process is called steam cracking or steam decomposition. However, there are some problems in the actual processing process, specifically:

[0006] 1. The contact area between water vapor and sludge is limited, especially in the internal area, which results in unsatisfactory decomposition of organic matter in sludge.

[0007] 2. The decomposed organic matter is difficult to separate from the sludge, and usually requires subsequent separation and enhanced treatment, which not only affects the sludge treatment efficiency but also increases the process cost. Summary of the Invention

[0008] Purpose of the invention: In order to overcome the deficiencies in the prior art, a microporous pyrolysis sludge treatment device is provided, which can achieve sufficient contact between water vapor and sludge, improve the decomposition effect of organic matter in sludge, and enhance the separation of decomposed organic matter from sludge, thereby improving the efficiency of sludge treatment.

[0009] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides a microporous pyrolysis sludge treatment device, including a rotating shaft, the rotating shaft is provided with a motor connection port, and a plurality of hollow tubes are arranged horizontally on the rotating shaft. Both ends of the hollow tubes are provided with plow-shaped turning devices, and the plow-shaped turning device includes a turning part and a pyrolysis part. The pyrolysis part is a hollow structure, and a plurality of steam micropores are provided on the front of the pyrolysis part. A vent is provided on the pyrolysis part, and the pyrolysis part is connected with the inside of the hollow tube through the vent. The turning part is provided on the pyrolysis part, and the adjacent hollow tubes are connected through a vent pipe. An air inlet pipe is provided on a hollow tube located at the side end, and the air inlet pipe is fitted on a bearing, and a steam intake hose is provided on the bearing.

[0010] Furthermore, metal films are provided on the front and back sides of the turning part and the pyrolysis part. The metal films have good high temperature resistance and strength, and can prevent the turning part and the pyrolysis part from being deformed due to high temperature.

[0011] Furthermore, the turning part is composed of a plurality of turning rods of different lengths, and the turning part is designed to be similar to a plow-shaped structure, which is conducive to turning the oil sludge to the pyrolysis part.

[0012] Furthermore, two plow-shaped material turning devices are symmetrically arranged at both ends of the hollow tube.

[0013] Furthermore, a reinforcing rod is provided on the back side of the material turning part.

[0014] Furthermore, the reinforcing rod is welded to all the turning rods.

[0015] Furthermore, the hollow tube is fixed on the rotating shaft by welding.

[0016] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0017] 1. When the plow-shaped turning device turns the material, the water vapor in the pyrolysis section can fully contact the oil sludge through the steam micropores, which greatly increases the contact area between the water vapor and the oil sludge and improves the decomposition effect of the organic matter in the oil sludge.

[0018] 2. The plow-shaped turning device can help separate the decomposed organic matter from the sludge, eliminating the need for subsequent separation and enhanced treatment processes, which not only improves the sludge treatment efficiency but also reduces the treatment cost.

[0022] The present invention is further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application.

[0023] like Figs. 1-3 As shown, the utility model provides a microporous pyrolysis sludge treatment device, including a rotating shaft 1, the rotating shaft 1 is provided with a motor connection port 11, and the motor is connected through the motor connection port 11. Three hollow tubes 3 are arranged horizontally on the rotating shaft 1, and the three hollow tubes 3 are welded and fixed on the rotating shaft 1. Both ends of the hollow tube 3 are provided with a plow-shaped turning device, and the two plow-shaped turning devices are symmetrically arranged at the two ends of the hollow tube 3. The plow-shaped turning device includes a turning part 7 and a pyrolysis part 5. The pyrolysis part 5 is a hollow structure. A plurality of steam micropores 51 are provided on the front of the pyrolysis part 5, and a vent 52 is opened on the pyrolysis part 5. The decomposition part 5 is connected with the inside of the hollow tube 3 through the vent 52. The turning part 7 is arranged on the pyrolysis part 5. The turning part 7 is composed of five turning rods of different lengths. A reinforcing rod 8 is arranged on the back of the turning part 7. The reinforcing rod 8 is welded on all the turning rods. Metal films 6 are provided on the front and back sides of the turning part 7 and the pyrolysis part 5. The adjacent hollow tubes 3 are connected through the vent pipe 4. An air inlet pipe 9 is provided on a hollow tube 3 located at the side end. The air inlet pipe 9 is fitted on a bearing 91. The bearing 91 is arranged on a bearing seat. A steam intake hose 2 is provided on the bearing 91. The steam intake hose 2 is connected to the gas source.

[0024] In this embodiment, the above-mentioned microporous pyrolysis type oil sludge treatment device is used as an example to perform auxiliary pyrolysis on oil sludge, specifically:

[0025] During the pyrolysis of oil sludge, auxiliary water vapor enters the hollow tube 3 through the steam inlet hose 2 and the air inlet pipe 9, and the high-temperature water vapor then enters the pyrolysis section 5 through the vent 52. The motor controls the rotation of the rotating shaft 1, thereby driving the upper and lower rows of plow-shaped turning devices to rotate. During the rotation process, the turning section 7 will turn the oil sludge onto the pyrolysis section 5, and the water vapor flows out through the steam micropores 51 and contacts the oil sludge. Since the contact occurs during the turning process, the water vapor can have a more comprehensive contact with the oil sludge.

[0026] In the above-mentioned sludge pyrolysis treatment, when the plow-shaped turning device is turning the material, the water vapor in the pyrolysis section 5 can fully contact the sludge through the steam micropores 51, greatly increasing the contact area between the water vapor and the sludge, and improving the effect of decomposing the organic matter in the sludge; and the turning operation of the plow-shaped turning device on the sludge can help the decomposed organic matter to separate from the sludge, eliminating the subsequent separation and enhanced treatment process, which not only improves the sludge treatment efficiency but also reduces the treatment cost.
