Description

TECHNICAL FIELD

[0001] The utility model relates to desulfurization device technical field, concretely relates to a spray device for desulfurization tower. BACKGROUND

[0002] In industrial production, in order to reduce air pollution, waste gas is treated by desulfurization, which is an essential link. As a common desulfurization equipment, the spray device inside the desulfurization tower plays a key role.

[0003] In the related art, the existing desulfurization tower spray device has the following problems: on the one hand, the spray head of the traditional desulfurization tower spray device has limited coverage due to the problem of spray angle, cannot fully contact with the waste gas in the desulfurization tower, and the particle size of the spray is uneven, the larger particles are likely to fall quickly under the action of gravity, cannot stay in the tower for enough time to react, resulting in poor desulfurization effect of waste gas; on the other hand, the material of the traditional spray device has poor corrosion resistance, when it is in contact with waste gas containing chemicals and desulfurizing agent for a long time, corrosion and damage are likely to occur, not only shortens the service life of the equipment, but also increases the cost of maintenance and replacement; in addition, the connection and sealing of the existing spray device and the desulfurization tower are poor, which is easy to cause the vibration of the spray pipe and the leakage of liquid or flue gas, affecting the normal operation of the whole desulfurization system.

[0004] Therefore, a new spray device for desulfurization tower is needed to solve the above technical problems. INVENTION CONTENTS

[0005] The utility model aims at providing a spray device for desulfurization tower to solve at least one aspect of the problems and defects in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A spray device for desulfurization tower, comprising:

[0008] The desulfurization tower body and the spray pipe, the inner side wall of the desulfurization tower body is provided with a fixed pipe seat;

[0009] The spray pipe is arranged in the desulfurization tower body, and one end of the spray pipe is arranged in the fixed pipe seat;

[0010] The pipe section of the spray pipe in the desulfurization tower body is provided with a plurality of vortex nozzles, and the spray angle of the vortex nozzles is 110-130 degrees;

[0011] The pipe section of the spray pipe outside the desulfurization tower body is provided with a fastening assembly.

[0012] The spray device for the desulfurization tower according to this scheme has at least the following technical effects:

[0013] This spray device for desulfurization towers, by setting several vortex nozzles at the bottom of the pipe section located inside the desulfurization tower body, with a spray angle of 110°-130° (preferably 120°), ensures that the desulfurization slurry droplets sprayed by the vortex nozzles can widely cover the flow area of ​​the flue gas inside the desulfurization tower body, increasing the contact area between the droplets and the flue gas, effectively promoting the mixing of the droplets and the flue gas, preventing the escape of waste gases such as carbon dioxide, greatly improving the desulfurization efficiency and effect of the waste gas, making the waste gas treatment more thorough, and better meeting environmental protection requirements.

[0014] As a further improvement of this utility model, the vortex nozzles are 2 to 4 in number.

[0015] Since there are 2 to 4 vortex nozzles, the droplets sprayed by the vortex nozzles can fully cover the exhaust gas inside the desulfurization tower, increase the contact area between the droplets and the flue gas, increase the reaction opportunity, and thus improve the desulfurization effect of the exhaust gas. In addition, the vortex nozzles can be used as backups for each other. Even if one vortex nozzle fails or needs maintenance, the other vortex nozzles can still maintain normal spraying effect, ensuring the continuous operation of the desulfurization tower and improving the continuity and efficiency of exhaust gas desulfurization.

[0016] As a further improvement of this utility model, the vortex nozzle is made of silicon carbide.

[0017] Because the vortex nozzle is made of silicon carbide, which has good high temperature resistance and corrosion resistance, it can prevent corrosion of the vortex nozzle in high temperature and in environments containing chemical substances and desulfurizing agents, thus ensuring the stability and reliability of the vortex nozzle in long-term use and extending its service life.

[0018] As a further embodiment of this utility model: the fastening assembly includes a nozzle insertion tube, the nozzle insertion tube is connected to one side of the desulfurization tower body, and the nozzle is inserted into the nozzle insertion tube.

[0019] Because the fastening assembly includes a nozzle insertion tube connected to one side of the desulfurization tower body, and the nozzle is inserted into the nozzle insertion tube, it can effectively support one end of the nozzle. After the nozzle is inserted into the nozzle insertion tube, the other end of the nozzle can be guided to the fixed pipe seat, which facilitates the installation of the nozzle and avoids the nozzle shaking or displacement caused by vibration or water flow impact. This effectively improves the connection stability of the nozzle and ensures that the vortex nozzle maintains a uniform spray flow and stable angle, thereby improving the desulfurization effect of the exhaust gas.

[0020] As a further embodiment of this utility model, a support plate is provided between the outer wall of the nozzle insertion pipe and the outer wall of the desulfurization tower body.

[0021] By installing a support plate between the outer wall of the nozzle insertion pipe and the outer wall of the desulfurization tower body, the support strength of the nozzle insertion pipe can be increased, which can absorb and disperse the vibration and shaking generated by the desulfurization tower body during operation. This avoids the spray angle deviation of the vortex nozzle caused by the shaking of the nozzle insertion pipe, and further improves the stability and uniformity of the vortex nozzle spraying effect.

[0022] As a further embodiment of this invention, the fastening assembly further includes a flange, which is disposed at the end of the nozzle insertion tube.

[0023] Since the fastening assembly also includes a flange, which is located at the end of the nozzle insertion tube, the nozzle insertion tube end is fixed and locked by the flange, so that the nozzle is firmly fixed in the nozzle insertion tube. This can effectively prevent the nozzle insertion tube from loosening or falling off, and ensure the stability and safety of the nozzle in the nozzle insertion tube; it can also prevent the leakage of flue gas, liquid and other media, and maintain the sealing of the desulfurization tower body; at the same time, the installation and removal of the flange can facilitate the maintenance or replacement of the nozzle or vortex nozzle, reduce equipment downtime and improve production efficiency.

[0024] As a further improvement of this utility model, a sealing gasket is provided between the flange and the nozzle insertion tube.

[0025] By placing a sealing gasket between the flange and the nozzle insertion pipe, the tiny gap between the flange and the nozzle insertion pipe can be effectively filled, preventing liquid or flue gas leakage and ensuring the sealing of the connection between the flange and the nozzle insertion pipe.

The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] like Figure 1 and Figure 2The present invention, as shown in this embodiment, provides a spraying device for a desulfurization tower, comprising: a desulfurization tower body 101 and a spray pipe 102. A fixed pipe seat 103 is provided on the inner wall of the desulfurization tower body 101. The spray pipe 102 is disposed throughout the desulfurization tower body 101, with one end of the spray pipe 102 positioned on the fixed pipe seat 103. A plurality of vortex nozzles 104 are provided at the bottom of the section of the spray pipe 102 located within the desulfurization tower body 101, with the spray angle of the vortex nozzles 104 being 110°-130°. A fastening assembly is provided on the section of the spray pipe 102 located outside the desulfurization tower body 101. The desulfurization slurry, pressurized by a desulfurization pump, flows into the spray pipe 102 and is atomized by the vortex nozzles 104. The atomized droplets combine with sulfur dioxide, HF, and other waste gases within the desulfurization tower body 101, neutralizing and reacting to form calcium sulfate, calcium sulfite, etc., which fall to the bottom of the desulfurization tower body 101.

[0038] Specifically, the spray device for the desulfurization tower has several vortex nozzles 104 installed at the bottom of the pipe section 102 located inside the desulfurization tower body 101. The spray angle of the vortex nozzles 104 is 110°-130°, preferably 120°. This ensures that the desulfurization slurry droplets sprayed by the vortex nozzles 104 can widely cover the flow area of ​​the flue gas inside the desulfurization tower body 101, increase the contact area between the droplets and the flue gas, effectively promote the mixing of the droplets and the flue gas, prevent the escape of waste gases such as carbon dioxide, greatly improve the desulfurization efficiency and effect of the waste gas, and make the waste gas treatment more thorough and better meet environmental protection requirements.

[0039] Furthermore, there are 2 to 4 vortex nozzles 104.

[0040] Specifically, since there are 2 to 4 vortex nozzles 104, the droplets sprayed by the vortex nozzles 104 can fully cover the exhaust gas inside the desulfurization tower body 101, increase the contact area between the droplets and the flue gas, increase the reaction opportunity, and thus improve the desulfurization effect of the exhaust gas. In addition, the vortex nozzles 104 can be used as backups for each other. Even if one vortex nozzle 104 fails or needs maintenance, the other vortex nozzles 104 can still maintain normal spraying effect, ensuring the continuous operation of the desulfurization tower and improving the continuity and efficiency of exhaust gas desulfurization.

[0041] Furthermore, the vortex nozzle 104 is made of silicon carbide.

[0042] Specifically, since the vortex nozzle 104 is made of silicon carbide, which has good high temperature resistance and corrosion resistance, it can prevent the vortex nozzle 104 from being corroded at high temperatures and in environments containing chemical substances and desulfurizing agents, thus ensuring the stability and reliability of the vortex nozzle 104 in long-term use and extending its service life.

[0043] likeFigure 1 and Figure 2 As shown, the fastening assembly includes a nozzle insertion tube 105, which is connected to one side of the desulfurization tower body 101, and a nozzle 102 is inserted into the nozzle insertion tube 105.

[0044] Specifically, since the fastening assembly includes a nozzle insertion tube 105, which is connected to one side of the desulfurization tower body 101, and the nozzle 102 is inserted into the nozzle insertion tube 105, it can effectively support one end of the nozzle 102. After the nozzle 102 is inserted into the nozzle insertion tube 105, the other end of the nozzle 102 can be guided to the fixed tube seat 103, which facilitates the installation of the nozzle 102 and avoids vibration or water flow impact causing the nozzle 102 to shake or shift. This effectively improves the connection stability of the nozzle 102 and ensures that the vortex nozzle 104 maintains a uniform spray flow and stable angle, thereby improving the desulfurization effect of the exhaust gas.

[0045] Furthermore, a support plate 106 is provided between the outer wall of the nozzle insertion pipe 105 and the outer wall of the desulfurization tower body 101.

[0046] Specifically, by setting a support plate 106 between the outer wall of the nozzle insertion pipe 105 and the outer wall of the desulfurization tower body 101, the support strength of the nozzle insertion pipe 105 can be increased, which can absorb and disperse the vibration and shaking generated by the desulfurization tower body 101 during operation, avoid the spray angle deviation of the vortex nozzle 104 caused by the shaking of the nozzle insertion pipe 105, and further improve the stability and uniformity of the spray effect of the vortex nozzle 104.

[0047] Furthermore, the fastening assembly also includes a flange 107, which is disposed at the end of the nozzle insertion tube 105.

[0048] Specifically, the fastening assembly also includes a flange 107, which is located at the end of the nozzle insertion tube 105. The flange 107 fixes and locks the end of the nozzle insertion tube 105, ensuring that the nozzle 102 is firmly fixed inside the nozzle insertion tube 105. This effectively prevents the nozzle insertion tube 105 from loosening or falling off, ensuring the stability and safety of the nozzle 102 within the nozzle insertion tube 105. It also prevents leakage of media such as flue gas and liquids, maintaining the airtightness of the desulfurization tower body 101. At the same time, the installation and removal of the flange 107 facilitates the maintenance or replacement of the nozzle 102 or the vortex nozzle 104, reducing equipment downtime and improving production efficiency.

[0049] Furthermore, a sealing gasket 108 is provided between the flange 107 and the nozzle insertion pipe 105.

[0050] Specifically, by providing a sealing gasket 108 between the flange 107 and the nozzle insertion pipe 105, the tiny gap between the flange 107 and the nozzle insertion pipe 105 can be effectively filled, preventing liquid or flue gas leakage and ensuring the sealing of the connection between the flange 107 and the nozzle insertion pipe 105.

[0051] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
