AI Technical Summary
The existing ammonia absorption tower spray device has a fixed spray head angle, which results in insufficient mixing of the sprayed water mist with the ammonia-containing waste gas, affecting the absorption effect.
By installing electric push rods, fixed plates, and hinged frames, the spray angle of the main spray pipe and the secondary spray pipe can be adjusted. Combined with the flow regulating valve, this ensures that the spray liquid and ammonia-containing waste gas are fully mixed.
This method achieves thorough mixing of the spray liquid and ammonia-containing waste gas, thereby improving the ammonia absorption effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of ammonia-containing tail gas absorption tower technology, specifically a spray device for an easily adjustable ammonia-containing tail gas absorption tower. Background Technology
[0002] Waste gas absorption towers are widely used in various fields such as power, medicine, chemical industry, electrical and electronic industry, metallurgy, and brewing. The waste gas absorption towers that have been used in the past can only neutralize and purify, and there has been no better way to recycle them for a long time, resulting in a lot of energy being wasted. Therefore, our company has successfully developed and manufactured a device for absorbing and reusing exhaust gas.
[0003] In existing ammonia absorption towers, the spray nozzles are angled at a fixed angle, which prevents the sprayed water mist from mixing fully with the ammonia-containing waste gas, thus affecting the absorption effect of the sprayed liquid on ammonia. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a spray device for an ammonia-containing tail gas absorption tower that is easy to adjust. Through the setting of electric push rod, fixed plate and hinge frame, the electric push rod can push the fixed plate to rotate around the hinge frame, so that the spray angle of the spray head on the lower side of the spray secondary pipe and spray main pipe can be adjusted, thereby allowing the spray liquid to be fully mixed with the ammonia-containing waste gas, ensuring the absorption effect of the spray liquid on ammonia gas, and effectively solving the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a spraying device for an easily adjustable ammonia-containing tail gas absorption tower, comprising a vertical pipe, a flow regulating valve installed on the upper part of the vertical pipe, a fixed plate provided on the upper side of the flow regulating valve, an electric push rod hinged to one side of the fixed plate, a hinge frame provided on the side of the fixed plate away from the electric push rod, a main spraying pipe connected to the lower end of the vertical pipe, secondary spraying pipes installed on both sides of the main spraying pipe, and spray heads installed on the lower side of the secondary spraying pipes.
[0006] Furthermore, the spray head has spray holes on its inner side, a dispersing ring is installed at the lower part of the spray holes, and a liquid inlet pipe is provided on the upper side of the fixing plate.
[0007] Furthermore, a dispersing net is installed on the inner side of the dispersing ring, and the dispersing net has round holes.
[0008] Furthermore, the spray head is connected to the secondary spray pipe by a thread, and the secondary spray pipe and the main spray pipe are integrally formed.
[0009] Furthermore, the vertical pipe is connected to the flow regulating valve via a flange, and the upper end of the vertical pipe is fixedly connected to the fixing plate.
[0010] Furthermore, the hinge frame and the fixing plate are an integral structure, and the liquid inlet pipe is connected to the upper end of the vertical pipe by a thread.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This utility model, through the setting of an electric push rod, a fixed plate, and a hinge frame, allows the main spray pipe and the secondary spray pipe to be driven by the electric push rod to rotate the fixed plate around the hinge frame, thereby adjusting the spray angle of the spray head on the lower side of the secondary spray pipe and the main spray pipe. This allows the spray liquid to be fully mixed with the ammonia-containing waste gas, ensuring the absorption effect of the spray liquid on ammonia. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-3 This embodiment provides a technical solution: a spray device for an easily adjustable ammonia-containing tail gas absorption tower, including a vertical pipe 4, a flow regulating valve 5 installed on the upper part of the vertical pipe 4, a fixed plate 6 provided on the upper side of the flow regulating valve 5, an electric push rod 7 hinged to one side of the fixed plate 6, a hinge frame 9 provided on the side of the fixed plate 6 away from the electric push rod 7, a spray main pipe 1 connected to the lower end of the vertical pipe 4, spray secondary pipes 2 installed on both sides of the spray main pipe 1, and spray heads 3 installed on the lower side of the spray secondary pipes 2.
[0019] like Figure 1-3As shown, a delivery hose is connected to the inlet pipe 8. The spray liquid enters the main spray pipe 1 and the secondary spray pipe 2 through the inlet pipe 8. The fixed plate 6 is hinged to the inner wall of the absorption tower through the hinge frame 9. The upper end of the electric push rod 7 is hinged to the inner wall of the absorption tower. When it is necessary to adjust the spray angle, the electric push rod 7 pushes the fixed plate 6 to rotate around the hinge frame 9, thereby adjusting the spray angle of the spray head 3 on the lower side of the main spray pipe 1 and the secondary spray pipe 2 on the fixed plate 6. This allows the spray liquid to be fully mixed with ammonia, thus ensuring the absorption effect of the spray liquid on ammonia. The flow regulating valve 5 can adjust the spray flow rate of the main spray pipe 1 and the secondary spray pipe 2, thereby ensuring the spraying effect.
[0020] The spray head 3 has a spray hole 11 on its inner side, a dispersing ring 10 is installed at the lower part of the spray hole 11, and an inlet pipe is provided on the upper side of the fixing plate.
[0021] A dispersing net 12 is installed on the inner side of the dispersing ring 10, and the dispersing net 12 has round holes.
[0022] The spray head 3 is connected to the secondary spray pipe 2 by a thread, and the secondary spray pipe 2 and the main spray pipe 1 are integrally formed.
[0023] The vertical pipe 4 is connected to the flow regulating valve 5 via a flange, and the upper end of the vertical pipe 4 is fixedly connected to the fixing plate 6.
[0024] The hinge frame 9 and the fixed plate 6 are integrated into one structure, and the liquid inlet pipe 8 is connected to the upper end of the vertical pipe 4 by a thread.
[0025] The working principle of the spray device for an easily adjustable ammonia-containing tail gas absorption tower provided by this utility model is as follows: Figures 1-3 As shown, a delivery hose is connected to the inlet pipe 8. The spray liquid enters the main spray pipe 1 and the secondary spray pipe 2 through the inlet pipe 8. The fixed plate 6 is hinged to the inner wall of the absorption tower through the hinge frame 9. The upper end of the electric push rod 7 is hinged to the inner wall of the absorption tower. When it is necessary to adjust the spray angle, the electric push rod 7 pushes the fixed plate 6 to rotate around the hinge frame 9, thereby adjusting the spray angle of the spray head 3 on the lower side of the main spray pipe 1 and the secondary spray pipe 2 on the fixed plate 6. This allows the spray liquid to be fully mixed with ammonia, thus ensuring the absorption effect of the spray liquid on ammonia. The flow regulating valve 5 can adjust the spray flow rate of the main spray pipe 1 and the secondary spray pipe 2, thereby ensuring the spraying effect.
[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
