Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a porous medium burner for petroleum volatile gas. Background Technology

[0002] Petroleum volatile gases typically refer to volatile organic compounds and gases such as methane released from crude oil or natural gas during oil extraction, transportation, and storage due to factors such as temperature changes or pressure reductions. Direct release of these gases into the atmosphere not only causes environmental pollution but may also contribute to the greenhouse effect. Therefore, in the petroleum industry, porous media burners are widely used to treat oilfield volatile gases and volatile organic compounds, effectively reducing the emission of harmful gases.

[0003] In existing technologies, volatile gases and air often fail to mix sufficiently and uniformly before entering the porous media layer, leading to incomplete combustion. For example, traditional introduction methods result in uneven airflow distribution, with some areas exhibiting excessively high or low volatile gas concentrations. Furthermore, existing structures struggle to effectively control the contact between the volatile gas-air mixture and the porous media layer. Concentrated contact with the porous media layer can cause localized overheating, reducing its lifespan and potentially posing safety hazards, such as rupture of the porous media layer due to localized overheating. This, in turn, affects combustion efficiency and equipment operational stability. Therefore, we propose a porous media burner for petroleum volatile gases to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a porous medium burner for petroleum volatile gases.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A porous medium burner for petroleum volatile gas includes a burner body, a fan fixedly embedded in the outer wall of the burner body, a burner head at one end of the burner body, a docking plate fixedly connected to one end of the burner head and the burner body, the two docking plates being fixedly connected, a volatile gas inlet pipe fixedly communicating with the top of the burner head, a conical head fixedly connected inside the burner head, multiple swirling guide grooves formed on the outer wall of the conical head, a mixing component provided on the outer wall of the conical head, and a porous medium layer fixedly connected inside the burner head.

[0007] Preferably, the mixing component includes a spiral guide vane, the outer wall of the conical head has a central hole, the inner wall of the central hole is fixedly connected to the outer wall of the spiral guide vane, a front tube is fixedly connected to the outer wall of the conical head, and a rear tube is fixedly connected to the outer wall of the conical head.

[0008] Preferably, the two ends of the spiral guide vane are located inside the front tube and the rear tube, respectively.

[0009] Preferably, two ignition electrodes are fixedly embedded in the outer wall of the combustion head.

[0010] Preferably, a control key is installed on the outer wall of the burner body.

[0011] Preferably, the outer wall of the burner body is provided with an air inlet duct.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution uses multiple swirling guide grooves to create a swirling airflow, allowing the air and associated gas to mix initially. Simultaneously, the spiral guide vanes inside the pre- and post-pipes further promote this mixing. This dual mixing method ensures that the associated gas and air can fully and evenly blend, and disperses the airflow, preventing the mixed airflow from concentrating on the porous media layer. This avoids localized overheating caused by concentrated contact with the porous media layer and reduces the probability of safety hazards such as porous media layer rupture.

[0022] Depend on Figures 1-4 As shown, a porous medium burner for petroleum volatile gas is disclosed, comprising a burner body 1 (BTG28P). A fan 2 is fixedly embedded in the outer wall of the burner body 1 (BTG28P). The fan 2 can stably introduce outside air into the burner head 3 to provide sufficient oxygen for combustion. The burner head 3 is provided at one end of the burner body 1 (BTG28P). The burner head 3 is the core area for mixing volatile gas with air and for combustion reaction, ensuring that the combustion reaction can be carried out efficiently within a controllable range.

[0023] The burner head 3 and the burner body 1 (BTG28P) are both fixedly connected to one end of a docking plate 4. The two docking plates 4 are fixedly connected. The top of the burner head 3 is fixedly connected to a volatile gas inlet pipe 5. The inside of the burner head 3 is fixedly connected to a conical head 6. The outer wall of the conical head 6 is provided with multiple swirl guide grooves 7. The conical structure of the conical head 6 helps to guide the flow direction of the airflow, so that the volatile gas and air can enter the swirl guide grooves 7 and the interior of the pre-pipe 11 and the post-pipe 10 more smoothly.

[0024] The burner head 3 has a porous medium layer 12 fixedly connected inside. The porous structure of the porous medium layer 12 increases the contact area between the gas and the medium, promotes the combustion reaction, and also plays a certain role in stabilizing the flame. The porous medium layer 12 can be a ceramic or metal porous material.

[0025] Two ignition electrodes 13 are fixedly embedded in the outer wall of the burner head 3. The ignition electrodes 13 ensure that the mixed gas can be successfully ignited and start combustion. The outer wall of the burner body 1 (BTG28P) is equipped with a control key 14 and an air inlet duct.

[0026] The outer wall of the conical head 6 is provided with a mixing component, which includes a spiral guide vane 9. The spiral guide vane 9 can further promote the mixing of air and associated gas. The outer wall of the conical head 6 is provided with a central hole 8. The inner wall of the central hole 8 is fixedly connected to the outer wall of the spiral guide vane 9. A front tube 11 is fixedly connected to the outer wall of the conical head 6. A rear tube 10 is fixedly connected to the outer wall of the conical head 6. The two ends of the spiral guide vane 9 are located inside the front tube 11 and the rear tube 10, respectively. The mixing component, including the conical head 6, is made of high-temperature resistant metal material.

[0027] Working principle: During use, the volatile gas enters the volatile gas inlet pipe 5 through the pipeline, and then the fan 2 introduces the outside air into the burner head 3. The airflow carries the volatile gas into the interior of multiple swirling guide grooves 7 and the pre-pipe 11. The airflow is guided by the multiple swirling guide grooves 7, so that the airflow is in a swirling state, which mixes the air with the volatile gas. The spiral guide vanes 9 inside the pre-pipe 11 and the rear pipe 10 also mix the air with the volatile gas. The mixing method can disperse the airflow, achieving the mixing effect while avoiding concentrated contact with the porous medium layer 12. The ignition electrode 13 operates to ignite and burn the gas.

[0028] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the fan 2 and the ignition electrode 13 to facilitate the control of the overall operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.
