AI Technical Summary
In existing waste gas treatment devices, the liquid droplets on the inner wall of the spray tower converge into small streams, failing to form an effective liquid film. This results in an insufficient contact area with the flue gas, leading to poor spraying performance.
The system adopts a combination structure of spray pipe and membrane laying pipe. The spray pipe rotates and sprays, forming a liquid film through the membrane laying pipe, which increases the contact area with the flue gas. The rotating nozzles compensate for dead corners, and the spray liquid is evenly distributed through the gap between the rotating ring and the support ring and the tower wall.
It improves the spraying effect, increases the gas-liquid contact area, improves the waste gas treatment efficiency, and avoids the impact of nozzle blockage on spraying quality.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of environmentally friendly weaving technology, specifically to a waste gas treatment device for heating during environmentally friendly weaving. Background Technology
[0002] With the increasing prominence of global environmental issues, governments worldwide are continuously strengthening their oversight of industrial waste gas emissions. The waste gas generated during the heating process in the environmentally friendly weaving industry contains various pollutants, such as volatile organic compounds and particulate matter. If emitted directly without effective treatment, it will cause serious air pollution, leading to environmental problems such as photochemical smog and acid rain, endangering human health and ecological balance. Therefore, to meet environmental regulations, companies must adopt effective waste gas treatment devices to reduce pollutant emissions.
[0003] Spray towers are commonly used equipment in waste gas treatment. Inside a spray tower, waste gas typically enters from the bottom and flows upwards; while the spray liquid is evenly sprayed downwards through a spray device at the top of the tower, forming countless tiny droplets. This creates a counter-current contact between the gas and liquid, significantly increasing the contact area and time between them, which is beneficial for the mass transfer process.
[0004] In existing waste gas treatment devices, the inner wall of the spray tower is such that droplets converge into small streams of liquid and flow down, failing to form a liquid film on the inner wall of the spray tower, resulting in an insufficient effective contact area with the flue gas. Utility Model Content
[0005] This invention addresses the technical problem in existing waste gas treatment devices where droplets converge into small streams of liquid flowing down the inner wall of the spray tower, preventing the formation of a liquid film on the inner wall and resulting in a small effective contact area with the flue gas. Therefore, this invention provides an environmentally friendly waste gas treatment device for weaving heating processes.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly waste gas treatment device for heating and weaving, comprising: a treatment tower, a waste gas inlet pipe connected to the lower side wall of the treatment tower, an exhaust pipe connected to the lower side wall of the treatment tower, a rotating joint rotatably connected to the top wall of the treatment tower, the rotating joint being connected to a gear, the gear meshing with a power output gear, a liquid inlet pipe rotatably connected to and connected to the upper end of the rotating joint, a liquid distribution pipe connected to and connected to the lower end of the rotating joint, multiple horizontally arranged spray pipes evenly distributed and connected to the outer circumference of the liquid distribution pipe, a nozzle connected to the lower part of both the spray pipe and the liquid distribution pipe, a film-laying pipe connected to the outer end of the spray pipe, the film-laying pipe being vertically arranged and having a gap between its outer side and the inner wall of the treatment tower, the gap being no more than 5mm.
[0007] Preferably, the outer end of the spray pipe is connected to the membrane laying pipe via a rotating ring, the spray pipe is connected to the rotating ring, the rotating ring is connected to the membrane laying pipe, a spray head is connected to the inner side of the membrane laying pipe, the lower surface of the rotating ring is in contact with the support ring, and the support ring is connected to the inner wall of the treatment tower within the gap between the outer side of the membrane laying pipe and the inner wall of the treatment tower.
[0008] Preferably, the spray pipe is located above the exhaust pipe.
[0009] Preferably, the inner end of the exhaust gas inlet pipe is connected to multiple interconnected branch pipes, and the upper part of the branch pipes is provided with air holes.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. During spraying, the power drives multiple spray pipes and nozzles to rotate synchronously. The rotating nozzles compensate for the dead spots in the spraying, and even if some nozzles are blocked, it will not have a significant impact on the spraying quality. The spray pipes drive the film-laying pipes to rotate. The rotation of the film-laying pipes spreads the small streams of liquid on the inner wall of the treatment tower evenly through the gaps to form a liquid film on the inner wall of the treatment tower. The formation of the liquid film effectively increases the effective contact area with the flue gas, thereby improving the spraying effect.
[0012] 2. The membrane-laying pipe can spray droplets into the center of the treatment tower through the nozzle, thereby increasing the contact between the droplets and the waste gas and improving the spraying effect. 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.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.
[0020] The following is in conjunction with the appendix Figure 1 - This embodiment describes an environmentally friendly waste gas treatment device for heating during weaving, comprising: a treatment tower 1, a waste gas inlet pipe 2 connected to the lower side wall of the treatment tower 1, an exhaust pipe 3 connected to the lower side wall of the treatment tower 1, a rotating joint 4 rotatably connected to the top wall of the treatment tower 1, the rotating joint 4 being connected to a gear 5, the gear 5 meshing with a power output gear, a liquid inlet pipe 6 rotatably connected to and connected to the upper end of the rotating joint 4, a liquid distribution pipe 7 connected to and connected to the lower end of the rotating joint 4, multiple horizontally arranged spray pipes 8 evenly distributed and connected to the outer circumference of the liquid distribution pipe 7, a nozzle 9 connected to the lower part of both the spray pipe 8 and the liquid distribution pipe 7, a film laying pipe 10 connected to the outer end of the spray pipe 8, the film laying pipe 10 being vertically arranged and having a gap between its outer side and the inner wall of the treatment tower 1, the gap being no more than 5mm.
[0021] During spraying, the power output gear drives gear 5 to rotate, gear 5 drives rotary joint 4 to rotate, and rotary joint 4 drives spray pipe 8 and film-laying pipe 10 to rotate. The spray liquid is injected into rotary joint 4 through inlet pipe 6. The spray liquid is broken into small droplets by spray pipe 8 and lower nozzle 9 of distributor pipe 7 and sprayed downwards. The exhaust gas enters through lower exhaust gas inlet pipe 2 and forms a countercurrent contact with the small droplets. Due to the concentration difference at the gas-liquid interface, pollutant molecules will pass through the gas film and enter the liquid film, and then dissolve in the liquid, completing the mass transfer process. In the process, a bag of pollutants falls to the bottom of the treatment tower 1, and the purified exhaust gas is discharged through the exhaust pipe 3. Multiple spray pipes 8 and nozzles 9 rotate synchronously. The rotation of nozzles 9 compensates for the dead spots in the spraying, and even if some nozzles 9 are blocked, it will not have a significant impact on the spraying quality. The spray pipes 8 drive the film-laying pipes 10 to rotate. The rotation of the film-laying pipes 10 spreads the small streams of liquid on the inner wall of the treatment tower 1 evenly through the gaps to form a liquid film. The formation of the liquid film effectively increases the effective contact area with the flue gas, thereby improving the spraying effect.
[0022] The outer end of the spray pipe 8 is connected to the membrane laying pipe 10 through the rotating ring 11. The spray pipe 8 is connected to the rotating ring 11, and the rotating ring 11 is connected to the membrane laying pipe 10. The inner side of the membrane laying pipe 10 is connected to the nozzle 9. The lower surface of the rotating ring 11 is in contact with the support ring 12. The support ring 12 is connected to the inner wall of the treatment tower 1 in the gap between the outer side of the membrane laying pipe 10 and the inner wall of the treatment tower 1.
[0023] The spray liquid enters the membrane-laying tube 10 through the rotating ring 11, and is then sprayed out through the inner nozzle 9. This further increases the number of droplets in contact with the exhaust gas, thereby improving the spraying effect.
[0024] The spray pipe 8 is located above the exhaust pipe 3.
[0025] To prevent contaminants from adhering to the spray pipe 8.
[0026] The inner end of the exhaust gas inlet pipe 2 is connected to multiple interconnected branch pipes 13, and the upper part of the branch pipes 13 is provided with air holes 14.
[0027] The exhaust gas enters the multiple branch pipes 13 through the exhaust gas inlet pipe 2, and is guided by the branch pipes 13 to different air holes 14 for upward discharge, resulting in more uniform gas discharge and better combination of pollutants with droplets.
