DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0038] In the description of the present utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0039] In addition, the terms "horizontal", "vertical" and the like do not mean that the components are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0040] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] As mentioned in the background technology, the combustion furnace in the prior art can only cope with a single working condition and cannot adapt to the fluctuating waste gas treatment volume in actual production. In order to improve the above problems, the present application provides a combustion furnace 10 and purification equipment, which can be flexibly configured according to different waste gas treatment needs to meet the treatment requirements in different scenarios and improve versatility and applicability.

[0042] Figure 1 This is a schematic diagram of a combustion furnace 10 provided in an embodiment of the utility model. Figure 2 Another schematic diagram of the combustion furnace 10 provided in the embodiment of the utility model is shown in FIG. Figure 1 and Figure 2 The present application provides a combustion furnace 10, which includes an adjusting member 700, an air inlet chamber 100, an air outlet chamber 500 and a combustion module 300 with adjustable length. The air inlet chamber 100, the combustion module 300 and the air outlet chamber 500 are sequentially connected along the length direction of the combustion module 300; the adjusting member 700 is connected to the air inlet chamber 100 and / or the air outlet chamber 500 for adjusting the ventilation volume.

[0043] Through the above arrangement, the ventilation volume of the air inlet chamber 100 and / or the air outlet chamber 500 can be adjusted by the adjusting member 700 to adapt to the fluctuating exhaust gas treatment volume; and the requirements of different exhaust gas treatment volumes can be met by adjusting the length of the combustion module 300. Specifically, the adjusting member 700 can be selectively connected to the air inlet chamber 100 or the air outlet chamber 500 to adjust the air intake or air outlet volume accordingly. Alternatively, the adjusting member 700 is simultaneously connected to the air inlet chamber 100 or the air outlet chamber 500 to synchronously adjust the air intake and air outlet volume. In addition, the adjusting member 700 and the combustion module 300 can also be selectively adjusted or adjusted together to adapt to the processing requirements in different scenarios.

[0044] Based on the above settings, taking the joint adjustment of the adjustment member 700 and the combustion module 300 as an example, when the exhaust gas treatment volume increases, the adjustment member 700 is adjusted to increase the ventilation volume and increase the length of the combustion module 300, so that the combustion furnace 10 can treat more exhaust gas; when the exhaust gas treatment volume decreases, the adjustment member 700 is adjusted to reduce the ventilation volume and shorten the length of the combustion module 300, so that the combustion furnace 10 can operate normally and avoid excessive treatment of exhaust gas.

[0045] Alternatively, if Figure 1 As shown, the combustion module 300 includes a plurality of combustion chambers 330 connected in series, and any two adjacent combustion chambers 330 can be detachably connected. Based on this, on the one hand, the staff can adjust the length of the combustion module 300 by adjusting the number of combustion chambers 330 to achieve the technical effect of energy saving and emission reduction; on the other hand, the staff can maintain and replace the independent combustion chambers 330, thereby reducing downtime and maintenance costs and simplifying repair and maintenance work.

[0046] It should also be noted that, compared with the customized combustion furnaces in the prior art, the combustion furnace 10 provided in the present application can greatly reduce the manufacturing cost and cycle of the equipment through the setting of a separate combustion chamber 330, so that it can be changed according to the client's usage requirements, saving time and financial costs during rectification, and is easy to assemble, greatly improving the company's production and manufacturing capabilities.

[0047] See also Figure 3 , Figure 3 Schematic diagram of a combustion chamber 330 provided in an embodiment of the utility model. To facilitate the series connection of the combustion chambers 330, the combustion module 300 further includes a connecting flange 310, and any two adjacent combustion chambers 330 are detachably connected through the connecting flange 310. It is understandable that the connecting flange 310 can withstand a large pressure, can ensure that the connection is tight and stable, and is not prone to loosening or deformation. And it also has good sealing performance, which can avoid leakage of insufficiently treated exhaust gas.

[0048] See also Figure 4 and Figure 5 Next, the air inlet chamber 100 and the air outlet chamber 500 will be described in detail. Figure 4 As shown, the combustion furnace 10 further includes a burner head 130 disposed in the air inlet chamber 100, and the burner head 130 is used to provide flames to the inner cavity of the air inlet chamber 100, so as to enhance the treatment effect of the exhaust gas and improve the purification efficiency. Optionally, the flame direction provided by the burner head 130 is perpendicular to the ventilation direction.

[0049] Furthermore, the combustion furnace 10 further includes a spoiler wall 110 disposed on the inner wall of the air inlet chamber 100, and the spoiler wall 110 is located at one end of the air inlet chamber 100 connected to the combustion module 300. It can be understood that the spoiler wall 110 can increase resistance on the air flow path, thereby increasing the residence time of the exhaust gas in the air inlet chamber 100 and improving the purification efficiency.

[0050] In addition, the combustion furnace 10 further includes an inlet flange 150 and an outlet flange 510, wherein the air inlet chamber 100 is detachably connected to the combustion chamber 330 via the inlet flange 150, and the air outlet chamber 500 is detachably connected to the combustion chamber 330 via the outlet flange 510, thereby achieving connection and sealing of the combustion furnace 10 and ensuring normal operation of the combustion furnace 10. It should also be noted that in order to ensure that the connection relationship in the above case is smoothly realized, the cross-sectional dimensions of the air inlet chamber 100, the combustion chamber 330 and the air outlet chamber 500 are the same.

[0051] Please refer again Figure 1 and Figure 2The adjusting member 700 is detachably connected to the air inlet chamber 100 and / or the air outlet chamber 500, and the adjusting member 700 is provided with a through hole 711 for circulating the exhaust gas. It can be understood that by reasonably arranging the through hole 711 on the adjusting member 700, it is convenient to control the ventilation volume in the combustion furnace 10, realize fine control of the combustion process, improve combustion efficiency, and reduce fuel waste.

[0052] Furthermore, since the ventilation volume is determined by the opening size of the through hole 711, there are multiple adjusting members 700 and the opening sizes of the through holes 711 of the multiple adjusting members 700 are different, the multiple adjusting members 700 can be switchably connected to the air inlet chamber 100 and / or the air outlet chamber 500 to adjust the ventilation volume.

[0053] Based on this, the staff can adjust the ventilation volume by replacing the adjusting member 700 with different opening sizes. Specifically, taking the adjusting member 700 connected to the air inlet chamber 100 as an example, when the exhaust gas treatment volume increases, the staff removes the original adjusting member 700 from the air inlet chamber 100 and replaces it with an adjusting member 700 with a larger opening size to increase the ventilation volume; otherwise, it is replaced with an adjusting member 700 with a smaller opening size. In addition, since the adjustment principle when the adjusting member 700 is connected to the air outlet chamber 500 is similar to the above, it will not be repeated here.

[0054] In other embodiments, a shielding member for adjusting the area of ​​the through hole 711 is provided at the through hole 711. It is understandable that when the waste gas treatment volume increases, the shielding member increases the area of ​​the through hole 711 to accommodate more air and wind, increase the ventilation volume, and increase the treatment efficiency; when the waste gas treatment volume decreases, the shielding member decreases the area of ​​the through hole 711, limits the number of air molecules in the through hole 711, reduces the ventilation volume, and reduces energy consumption.

[0055] Specifically, the shielding member may be a rotating structure including a plurality of thin sheets or blades. When the ventilation volume increases, the thin sheets or blades will shrink, so that the area of ​​the through hole 711 becomes larger; when the ventilation volume decreases, the thin sheets or blades will expand, so that the area of ​​the through hole 711 decreases. In addition, the shielding member may also adopt a telescopic structure to control the area of ​​the through hole 711 by telescopic length; or adopt a sliding structure to change the size of the through hole 711 by sliding up and down, left and right, and front and back to achieve a ventilation effect; or adopt a sensor and a control system to realize automatic adjustment of the area of ​​the through hole 711 and automatically adjust the ventilation volume according to environmental conditions and needs.

[0056] Furthermore, the through hole 711 is a circular hole, and the center of the air inlet chamber 100, the center of the combustion module 300 and the center of the air outlet chamber 500 are all located on the axis of the through hole 711. Figure 2Flowing in the direction of the arrow shown ensures the consistency of the gas flow direction, avoiding unnecessary distortion or diversion that affects the exhaust gas treatment efficiency; and also helps to ensure that the exhaust gas is evenly distributed during treatment, avoiding local concentrations that are too high or too low.

[0057] It should also be noted that since the linear flow pattern of the circular through hole 711 is relatively simple and has uniform airflow distribution characteristics, the gas can pass through the through hole 711 more smoothly, while the corners of the square or other complex shaped through holes 711 are prone to resistance or eddy currents, affecting the gas flow.

[0058] In addition, it should be noted that the number of through holes 711 can be set to multiple according to needs. When the number of through holes 711 is multiple, the sum of the areas of the multiple through holes 711 is the ventilation volume of the adjustment member 700. Accordingly, when the ventilation volume needs to be adjusted, the staff can achieve it by replacing the adjustment member 700 with a different number of through holes 711, or adjusting the shielding member to shield a certain number of through holes 711, so as to change the total ventilation area of ​​the through holes 711.

[0059] Please refer again Figure 1 and Figure 2 The adjusting member 700 at least partially extends into the air inlet chamber 100 and / or the air outlet chamber 500, and is movably connected to the air inlet chamber 100 and / or the air outlet chamber 500 to define a ventilation hole with an adjustable ventilation area between the walls of the air inlet chamber 100 and / or the air outlet chamber 500.

[0060] Based on the above arrangement, taking the extension of the adjusting member 700 into the air inlet chamber 100 as an example, the staff can adjust the distance between the adjusting member 700 and the wall of the air inlet chamber 100 by pulling out the adjusting member 700, thereby adjusting the size of the ventilation hole and changing the ventilation volume. In addition, it should be noted that in the above process, since the adjusting member 700 can be in contact with the wall of the air inlet chamber 100, a positioning groove that cooperates with the adjusting member 700 can be provided on the wall of the air inlet chamber 100 to avoid the misalignment of the adjusting member 700 during use, which affects the replacement efficiency. In addition, the principle of the adjusting member 700 extending into the air outlet chamber 500 is similar to the above, and will not be repeated here.

[0061] like Figure 1 As shown, as an optional embodiment, the adjusting member 700 includes an adjusting plate 710 and a blind plate 730, and the combustion furnace 10 also includes a sealing flange 750. One end of the adjusting plate 710 passes through the sealing flange 750 and extends into the air inlet chamber 100 and / or the air outlet chamber 500, and the other end of the adjusting plate 710 is connected to the blind plate 730. The sealing flange 750 is connected between the blind plate 730 and the outer wall of the air inlet chamber 100 and / or the air outlet chamber 500, and a heat insulating member 770 is also provided between the sealing flange 750 and the adjusting member 700.

[0062] Specifically, taking the connection between the adjusting member 700 and the air inlet chamber 100 as an example, the staff can adjust the distance between the adjusting plate 710 and the wall of the air inlet chamber 100 or replace the adjusting plate 710 by pulling out the blind plate 730. The setting of the sealing flange 750 avoids direct contact between the blind plate 730 and the outer wall of the air inlet chamber 100, effectively isolates heat radiation, improves the safety of the working environment, and reduces the occurrence of accidents; and the heat insulation member 770 is filled between the sealing flange 750 and the adjusting member 700, ensuring the sealing of the air inlet chamber 100 and avoiding the mutual leakage of external air and exhaust gas. Since the connection between the adjusting member 700 and the air outlet chamber 500 is similar to the above, it will not be repeated here.

[0063] Taking this embodiment as an example, the working principle and working process of the combustion furnace 10 provided in this application are as follows:

[0064] When the amount of waste gas to be treated is large, the adjusting member 700 of the air inlet chamber 100 and the air outlet chamber 500 is replaced with an adjusting plate 710 with a larger aperture of the through hole 711 to increase the ventilation volume, and at the same time, a larger number of combustion chambers 330 are connected in series to increase the combustion module 300; when the amount of waste gas to be treated is small, the adjusting member 700 of the air inlet chamber 100 and the air outlet chamber 500 is replaced with an adjusting plate 710 with a smaller aperture of the through hole 711 to reduce the ventilation volume, and at the same time, a smaller number of combustion chambers 330 are connected in series to shorten the combustion module 300.

[0065] In summary, the present application provides a combustion furnace 10, which includes an adjusting member 700, an air inlet chamber 100, an air outlet chamber 500, and a combustion module 300 with adjustable length. The air inlet chamber 100, the combustion module 300, and the air outlet chamber 500 are sequentially connected along the length direction of the combustion module 300; the adjusting member 700 is connected to the air inlet chamber 100 and / or the air outlet chamber 500 for adjusting the ventilation volume. Based on the above arrangement, the ventilation volume of the air inlet chamber 100 and / or the air outlet chamber 500 can be adjusted by the adjusting member 700 to adapt to the fluctuating exhaust gas treatment volume; and the length of the combustion module 300 can be adjusted to meet the requirements of different exhaust gas treatment volumes.

[0066] In addition, the present application also provides a purification device, which includes the above-mentioned combustion furnace 10, so it can also adjust the ventilation volume through the adjustment part 700; and it also meets different processing air volume requirements by adjusting the specific length of the combustion module 300, thereby avoiding energy waste.

[0067] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
