Abstract
Description
Technical Field
[0001] This utility model relates to the field of burner technology, specifically to a converter burner. Background Technology
[0002] A converter burner is a device that mixes fuel (such as oil or gas) with air in a specific ratio and then burns it, primarily used to achieve efficient thermal energy conversion. Its core function is to ensure complete combustion of fuel through specific design, thereby improving energy utilization efficiency. It is widely used in industrial production scenarios that require a stable heat source.
[0003] like Figure 1 As shown, the existing converter burner includes a burner body 1. Since the burner body 1 is made entirely of metal, it has strong thermal conductivity. As a result, during the operation of the burner body 1, heat will be rapidly radiated outward from the burner body 1, causing the temperature near the end of the burner body 1 to drop to 450-550°C. Within this temperature range, carbon monoxide will undergo a disproportionation reaction, and methane will also decompose on the surface of the burner body 1 under catalysis, thereby generating carbon elemental that is deposited on the inner wall of the burner body 1, causing blockage of the flow channels of the burner body 1, thus affecting the efficiency of the converter.
[0004] In the existing technology, to solve the above-mentioned carbon deposition problem, two methods are generally used: ceramic burners or heat insulation coatings are applied to the outer wall of the burner body 1. However, ceramic burners are fragile and heat insulation coatings are easy to fall off, which undoubtedly increases the cost and cannot solve the carbon deposition problem of the burner body 1 in a long-term and stable manner. Utility Model Content

[0014] Preferably, the heat insulation sleeve has a plurality of mounting holes along its circumference at one end near the sliding ring, and the sealing sleeve has a plurality of threaded blind holes evenly distributed along its circumference. The plurality of mounting holes are arranged one-to-one with the plurality of threaded blind holes, and the plurality of locking elements freely pass through the plurality of mounting holes and are threadedly connected to the plurality of threaded blind holes.

[0024] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:
[0025] like Figure 2 and Figure 5As shown, an embodiment of this utility model provides a converter burner, including a burner body 1 and a heat insulation component circumferentially sleeved in the middle of the burner body 1. The heat insulation component includes a fixing member fixedly sleeved on the burner body 1, a connecting member connected to the side of the fixing member away from the air inlet end of the burner body 1, a heat insulation component sleeved on the outside of the burner body 1, and a sealing member slidably sleeved on the burner body 1. The fixing member is arranged near the air inlet end of the burner body 1, and the sealing member is arranged near the air outlet end of the burner body 1. One side of the heat insulation component is detachably connected to the connecting member, and the sealing member is connected to the other side of the heat insulation component. A plurality of locking members are provided between the sealing member and the heat insulation component to fix the sealing member and the heat insulation component.
[0026] The heat insulation component is connected to the connector and sealed with a sealing component. Then, several locking components are used to fix the sealing component and the heat insulation component, so that a heat insulation structure is formed between the heat insulation component and the burner body 1. This reduces heat loss in the middle section of the burner, effectively improves the temperature control capability inside the burner body 1, and maintains the temperature above the critical temperature for carbonization, thereby inhibiting the formation of elemental carbon.
[0027] like Figure 2-5 As shown, according to another embodiment of the present invention, the converter burner further optimizes its heat insulation component, connecting component, fixing component, sealing component, and locking component. The heat insulation component includes a heat insulation sleeve 2 sleeved on the outside of the burner body 1 and a heat insulation layer 5 disposed between the heat insulation sleeve 2 and the burner body 1. One end of the heat insulation sleeve 2 is detachably connected to the connecting component, and the sealing component is connected to the other end of the heat insulation sleeve 2. Several locking components are disposed between the heat insulation sleeve 2 and the sealing component. Preferably, the heat insulation layer 5 is made of a low thermal conductivity heat insulation material, which includes, but is not limited to, nano-aerogel felt, aluminum silicate fiber blanket, etc.
[0028] One end of the heat insulation sleeve 2 is provided with an internal thread, and the connector includes an external threaded sleeve 31 fixedly installed on the fixing member. The external threaded sleeve 31 is sleeved on the outside of the burner body 1 and is threadedly connected to the internal thread of the heat insulation sleeve 2.
[0029] The fastener includes a fixing ring 3 fixedly sleeved on the burner body 1, and the external threaded sleeve 31 is coaxially and fixedly connected to the fixing ring 3. The outer diameter of the fixing ring 3 is the same as the outer diameter of the heat insulation sleeve 2.
[0030] The sealing element includes a sliding ring 4 that is slidably sleeved on the burner body 1. A sealing sleeve 41 is coaxially fixedly installed on one end of the sliding ring 4 facing the heat insulation sleeve 2. The outer diameter of the sealing sleeve 41 is the same as the inner diameter of the heat insulation sleeve 2. The outer diameter of the sliding ring 4 is the same as the outer diameter of the heat insulation sleeve 2. Several locking elements are disposed between the heat insulation sleeve 2 and the sealing sleeve 41.
[0031] The heat insulation sleeve 2 has a plurality of mounting holes 21 circumferentially formed on one end near the sliding ring 4, and the sealing sleeve 41 has a plurality of threaded blind holes 42 uniformly formed on its circumferential direction. The plurality of mounting holes 21 are arranged one-to-one with the plurality of threaded blind holes 42. A plurality of locking members are threadedly connected to the plurality of threaded blind holes 42 after freely passing through the plurality of mounting holes 21. Each locking member includes a bolt 22 that freely passes through the corresponding mounting hole 21 and is threadedly connected to the corresponding threaded blind hole 42. Preferably, the diameter of the mounting hole 21 facing the outside of the heat insulation sleeve 2 is larger than the diameter of the other end, so that when the bolt 22 is installed, the bolt head can be recessed into the larger diameter end of the mounting hole 21, reducing the space occupied by the bolt 22.
[0032] To ensure a good seal, sealing gaskets or sealing rings can be installed between the heat insulation sleeve 2 and the fixing ring 3, and between the heat insulation sleeve 2 and the sliding ring 4.
[0033] The working principle of this utility model is as follows: When using this utility model, the internal thread of one end of the heat insulation sleeve 2 is threadedly connected to the external thread sleeve 31, and the heat insulation layer 5 is filled between the heat insulation sleeve 2 and the burner body 1. After the heat insulation layer 5 is filled, the sealing sleeve 41 is inserted into the heat insulation sleeve 2, and each threaded blind hole 42 is arranged to face the mounting hole 21. Then, bolts 22 are installed in each mounting hole 21 and screwed into the corresponding threaded blind hole 42. Thus, the sealing sleeve 41 and the heat insulation sleeve 2 are fixed by the cooperation of several bolts 22 and several threaded blind holes 42, thereby completing the sealing of the heat insulation sleeve 2. Subsequently, the above method can be reversed to replace the heat insulation layer 5 between the heat insulation sleeve 2 and the burner body 1.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it.
