Technical Field

[0001] The utility model relates to the technical field of gasifier burner nozzles, in particular to an anti-corrosion protection device for a gasifier burner nozzle. Background Art

[0002] The burner is one of the key components of the gasifier. Its main function is to introduce fuel and gasifying agent into the gasifier at a certain speed. Under the dynamic action of the high-speed injected gasifying agent, the fuel and gasifying agent are fully mixed and then an incomplete combustion chemical reaction occurs.

However, some combustible gases tend to release elements such as sulfur and chlorine when burning. These gases tend to corrode the combustion reaction site of the burner. In addition, since the burner in the prior art lacks a corresponding air intake regulating device, continuous and long-term combustion is likely to affect the service life of the burner due to corrosion problems.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] See also Figure 1-Figure 4A gasifier burner anti-corrosion protection device includes a gasifier burner body 1, which is composed of an air inlet pipe 105 and a generating pipe 106. The air inlet pipe 105 is respectively provided with a first air inlet port 101 and a second air inlet port 102. A blocking plate 108 and a movable connecting rod 109 are also provided inside the air inlet pipe 105. The blocking plate 108 and the movable connecting rod 109 are used to adjust the air inlet opening and closing degree of the air inlet pipe 105.

[0025] There are two blocking plates 108, and both blocking plates 108 are movably set inside the corresponding storage grooves 110. At the same time, one side surface of each blocking plate 108 is movably connected to one end of a movable connecting rod 109, and the other end of each movable connecting rod 109 is also movably set inside the connecting base 113.

[0026] A sliding groove 111 is further provided inside each receiving groove 110 , and each blocking plate 108 is movably disposed inside the sliding groove 111 via an integrally provided sliding bar 122 .

[0027] An adjusting gear 114 is also integrally provided at the bottom end of the connecting base 113 , and the adjusting gear 114 is movably arranged on the inner wall of the air inlet pipe 105 through a rotating rod, and the adjusting gear 114 is also meshed with the adjusting rack 115 .

[0028] The adjustment rack 115 is slidably arranged in a corresponding stabilizing slide groove 117 through a stabilizing slide rod 116 arranged on the surface. The stabilizing slide groove 117 is also opened on the inner wall of the air intake pipe 105 .

[0029] One end of the adjusting rack 115 is fixedly connected to the connecting spring 119 , while the other end of the connecting spring 119 is fixedly installed on the inner wall of the air intake pipe 105 . The other end of the adjusting rack 115 is fixedly connected to the traction rope 118 .

[0030] The other end of the traction rope 118 is fixedly connected to the push block 121 , and the push block 121 is movably arranged inside the second air inlet 102 . At the same time, the traction rope 118 is also wound around the connecting wheel 120 , and the connecting wheel 120 is used to adjust the angle of the traction rope 118 .

[0031] In this embodiment: when the combustible gas and the corresponding protective gas required by the gasifier burner body 1 are respectively injected into the inlet pipe 105 from the first air inlet 101 and the second air inlet 102, since the push blocks 121 are movably arranged inside the two second air inlets 102, when the protective gas is injected into the second air inlet 102, the push blocks 121 will move correspondingly inside the second air inlet 102 under the action of the protective gas;

[0032] Since one end of the traction rope 118 is connected to each push block 121, and the other end of the traction rope 118 is fixedly connected to the adjustment rack 115 movably arranged inside the stable slide groove 117, when the push block 121 is moving, the adjustment rack 115 will also move accordingly under the action of the traction rope 118;

[0033] At the same time, since the adjusting rack 115 is also meshed with the adjusting gear 114, and the adjusting gear 114 is movably arranged on the inner wall of the intake pipe 105, and is also fixedly connected to the connecting base 113, when the adjusting rack 115 moves, the connecting base 113 can be adjusted to a corresponding angle under the action of the adjusting rack 115 and the adjusting gear 114;

[0034] The connection base 113 is also movably connected with a movable connecting rod 109, and the other end of the movable connecting rod 109 is movably connected to the blocking plate 108, so that when the connection base 113 is adjusted in angle, the blocking plate 108 will move up and down accordingly inside the storage slot 110 under the adjustment of the movable connecting rod 109;

[0035] When the blocking plate 108 is gradually opened, the protective gas and the corresponding combustible gas will be injected into the generating tube 106 from the air inlet pipe 105, and the corresponding combustion effect will be achieved under the action of the ignition generator 103;

[0036] Through the above-mentioned method, the opening and closing degree of the sealing plate 108 can be adjusted to a certain extent by moving the push block 121, and the amount of gas injected into the generating tube 106 can be effectively controlled by adjusting the opening and closing degree of the sealing plate 108, so as to avoid the problem in the prior art that the flue gas is too large due to the uncontrollable combustible gas, so as to corrode the inside of the generating tube 106;

[0037] It should be noted that since a limit block 112 is also provided inside the second air inlet 102, the user can effectively control the moving distance of the push block 121, thereby preventing the push block 121 from moving excessively and escaping from the second air inlet 102;

[0038] It should be noted that since the push block 121 is provided with an air outlet, the amount of the protective gas passing through the push block 121 is fixed. Even if the air pressure inside the second air inlet 102 is relatively high, the input amount of the protective gas is still relatively stable.

[0039] It should be noted that, on the one hand, a stabilizing slide bar 116 is provided on the adjusting rack 115, and the adjusting rack 115 is slidably arranged inside the stabilizing slide groove 117 through the stabilizing slide bar 116, so that when the adjusting rack 115 moves, it can perform a more stable relative movement inside the stabilizing slide groove 117. On the other hand, since a connecting spring 119 is fixedly connected to the other end of the adjusting rack 115, when the amount of the protective gas is reduced or stopped, the adjusting rack 115 can also perform a corresponding reset effect through the connecting spring 119, so that the blocking plate 108 can be adjusted in the opposite angle.

[0040] It should be noted that the connection wheel 120 is also provided to facilitate a better angle adjustment effect of the traction rope 118 .

[0041] It should be noted that the blocking plate 108 is slidably arranged inside the corresponding sliding groove 111 through an integrally arranged sliding bar 122, and in this way, the blocking plate 108 can be relatively stable during the movement.

[0042] It should be noted that the traction rope 118 is made of a high temperature resistant material. When the generating tube 106 is burning, the temperature transmitted to the intake pipe 105 will not affect the pulling effect of the traction rope 118 .

[0043] Embodiment 2

[0044] This embodiment is an improvement made on the basis of the first embodiment. Figure 1 and Figure 2 As shown, the air intake pipe 105 and the generating pipe 106 are connected via corresponding connecting flanges 104 , and a corrosion-resistant coating 107 is provided on the inner wall of the generating pipe 106 , and an ignition generator 103 is also provided on the generating pipe 106 .

[0045] In this embodiment: since a corrosion-resistant coating 107 is also provided on the inner wall of the generating tube 106, this also provides a corresponding protective effect on the inside of the generating tube 106 to a certain extent, and this arrangement further improves the corrosion resistance efficiency of the gasifier burner body 1.

[0046] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
