Description

Technical Field

[0001] This utility model relates to the technical field of byproduct treatment in gasification processes, and specifically discloses a high-efficiency condensing cyclone scraping oil remover. Background Technology

[0002] In the biomass gasification process, tar is an unavoidable byproduct. Its efficient and environmentally friendly treatment is crucial for improving the overall operational efficiency of the gasification system and reducing environmental pollution. Traditional methods often suffer from low efficiency, high energy consumption, and susceptibility to clogging. For example, some traditional oil removal equipment relies solely on gravity settling or simple filtration devices to remove tar. However, these methods cannot effectively handle fine tar particles in the gas stream, resulting in large amounts of tar being discharged with the gas, reducing the efficiency of the gasification system and polluting the environment. Furthermore, traditional oil removal equipment is prone to clogging due to tar accumulation during operation, requiring frequent shutdowns for cleaning, increasing maintenance costs and equipment downtime. Therefore, developing a new type of oil removal machine that can effectively remove tar while also utilizing waste heat is particularly important. Utility Model Content

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] This embodiment discloses a high-efficiency condensing cyclone scraping type oil remover, referring to... Figure 1The system comprises an inner cylinder 1 and an outer cylinder 2 coaxially fitted together. An air inlet pipe 4 connects to the side wall of the inner cylinder 1, an air outlet pipe 5 connects to the top, and an oil drain pipe 6 connects to the bottom. An annular space is formed between the inner cylinder 1 and the outer cylinder 2. The outer cylinder 2 is equipped with a water inlet pipe 8 and a water outlet pipe 9 connecting to the annular space. A rotating shaft 10 is also provided in the inner cylinder 1, driven by a drive component 11, which can be a speed-regulating motor. The surface of the rotating shaft 10 is provided with several bristles 12 extending radially along the shaft. This structural design allows the biomass gas to form a cyclone effect in the inner cylinder 1 after entering through the air inlet pipe 4, increasing the contact area between the gas and the pipe wall, promoting tar condensation, and then allowing the condensed tar to flow down the pipe wall and be discharged through the oil drain pipe 6. Simultaneously, cooling water introduced through the water inlet pipe 8 circulates in the annular space, absorbing waste heat from the biomass gas and achieving comprehensive energy utilization. The drive unit 11 can drive the brush bristles 12 on the rotating shaft 10 to rotate at a speed greater than the air intake speed, so that the brush bristles 12 can shear the flue gas during high-speed rotation. The strong adsorption of the brush bristles 12 can capture residual tar and small particles. At the same time, due to the increase in the rotation speed of the flue gas, the fine particles and tar are thrown onto the barrel wall by centrifugal force and flow into the bottom of the barrel, further improving the oil removal efficiency and gas purification effect.

[0020] As a preferred embodiment, the bristles 12 are located near the bottom of the inner cylinder 1 on the rotating shaft 10. Positioning the bristles 12 near the bottom of the inner cylinder 1 allows for better capture of oil particles that are relatively heavier than air. Since tar and fine particles tend to aggregate towards the inner cylinder 1 wall under centrifugal force and eventually settle to the bottom, placing the bristles 12 near the bottom more effectively adsorbs these settled oil particles, preventing them from being re-entrained by the airflow and discharged with the gas. This improves oil removal efficiency, ensures the cleanliness of the discharged gas, and further enhances the performance and environmental benefits of the oil separator.

[0021] As a preferred embodiment, the bristles 12 are radially distributed around the rotating shaft 10. The radially distributed bristles 12 can more comprehensively cover the inner cylinder wall, making the bristles 12 more stable and covering a larger area when rotating. This more effectively adsorbs and removes tar and small particles from the inner cylinder wall, improves oil removal efficiency, reduces tar residue on the inner cylinder wall, ensures the cleanliness of the inner cylinder wall, and extends the service life of the equipment.

[0022] As a preferred embodiment, the brush bristles 12 are arranged in multiple layers along the axial direction of the rotating shaft 10. This multi-layered design increases the contact area and frequency between the bristles 12 and the flue gas, further improving the adsorption effect and more thoroughly removing tar and fine particles from the flue gas. Simultaneously, the multi-layered brush bristles 12 can treat the flue gas at different heights, ensuring that the flue gas within the inner cylinder 1 is purified more effectively, thus improving the overall performance of the oil separator.

[0023] As a preferred embodiment, the system also includes an oil collecting funnel 3 connected to the bottom of the inner cylinder 1, with an oil drain pipe 6 connected to the oil collecting funnel 3. The oil collecting funnel 3 allows for the concentrated collection of condensed tar, facilitating its discharge and subsequent processing. The funnel 3 also enables the tar to flow more smoothly into the oil drain pipe 6, preventing tar accumulation and residue at the bottom of the inner cylinder 1, improving oil removal efficiency, and facilitating unified tar treatment, thus reducing environmental pollution.

[0024] As a preferred embodiment, the oil collecting funnel 3 is also connected to a slag discharge pipe 7, the height of which is lower than the height of the oil discharge pipe 6. The slag discharge pipe 7 allows impurities and residues generated during the oil removal process to be discharged, preventing them from accumulating in the oil collecting funnel 3, clogging the oil discharge pipe, and affecting the normal operation of the oil separator. The lower height of the slag discharge pipe 7 ensures that tar and impurities can be smoothly separated and discharged, guaranteeing the efficient operation of the oil separator and improving the stability and reliability of the equipment.

[0025] As a preferred embodiment, the air inlet pipe 4 is connected tangentially to the cross-section of the inner cylinder 1. This connection method allows the biomass gas to form a strong cyclone effect after entering the inner cylinder 1, increasing the contact area between the gas and the pipe wall and promoting the condensation and separation of tar. Tangential air intake can improve the tar condensation efficiency, reduce the amount of tar residue in the gas, improve the treatment effect of the oil separator, and also facilitate subsequent gas purification and utilization.

[0026] As a preferred embodiment, the inlet pipe 8 is connected to the top of the annular space, and the outlet pipe 9 is connected to the bottom of the annular space. This connection method allows cooling water to enter the annular space from the top and flow out from the bottom, forming a top-down flow path. This flow direction is conducive to the cooling water fully absorbing the waste heat in the biomass gas, improving the waste heat utilization efficiency, and also facilitates the recycling of cooling water, reducing energy consumption and improving the economy and environmental friendliness of the oil separator.

[0027] The technical solution provided by this utility model has been described in detail above. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
