Description

Technical Field

[0001] This utility model belongs to the field of waste gas pollution treatment technology, specifically relating to a pollution control sprayer. Background Technology

[0002] Industrial waste gases often contain large amounts of harmful substances, such as sulfur dioxide, nitrogen oxides, particulate matter, and volatile organic compounds. Direct emission of these gases into the atmosphere severely damages air quality, causing environmental problems such as acid rain and smog, and endangering human health and ecological balance. To effectively control waste gas pollution and protect the ecological environment, waste gas treatment technologies have emerged. Spray treatment, as a common and effective waste gas treatment method, is widely used in various industrial waste gas treatment scenarios. Its working principle involves spraying an absorbent liquid into the waste gas, causing the harmful substances in the waste gas to react chemically or be physically adsorbed by the absorbent liquid, thereby removing the harmful substances from the waste gas. In the spray treatment process, the sprayer plays a crucial role; its performance directly affects the effectiveness and efficiency of waste gas treatment.

[0003] Most existing spray head designs use a single nozzle or a simple combination of multiple nozzles, resulting in limited spray coverage and an inability to evenly cover the entire waste gas treatment space. This prevents some waste gas from fully contacting the absorbent liquid, reducing the effectiveness of waste gas treatment. Furthermore, the spray pattern and shape design of the spray heads are not optimal, leading to insufficient impact and penetration of the absorbent liquid, making it difficult to effectively remove harmful substances from the waste gas.

[0004] In view of this, we propose a pollution control sprayer to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the technical problem that the spray head design in the above-mentioned prior art mostly adopts a single nozzle or a simple combination of multiple nozzles, which has a limited spray coverage range and cannot evenly cover the entire waste gas treatment space.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pollution control sprayer includes an inlet pipe, a main spray pipe, branch spray pipes, and spray heads. The inlet pipe is connected to the main spray pipe, the branch spray pipes are evenly distributed on both sides of the main spray pipe and connected to the main spray pipe, and the spray heads are evenly distributed at the bottom of the branch spray pipes.

[0008] The spray head includes a funnel-shaped spray guide hood with a water inlet groove and a number of narrow-angle fan-shaped nozzles that are arranged in a ring at equal intervals inside the funnel-shaped spray guide hood and are connected to the water inlet groove.

[0009] Preferably, the main spray pipe is equipped with a flow regulating valve to adjust the flow rate of the absorbent entering the spray branch pipes.

[0010] Preferably, a pressure sensor is also installed on the spray branch pipe. The pressure sensor is electrically connected to the controller of the pollution control system, and the controller is electrically connected to the flow regulating valve. When the pressure sensor detects an abnormal pressure in the spray branch pipe, the controller controls the flow regulating valve to adjust the flow rate to ensure stable spray pressure.

[0011] Preferably, the main spray pipe is equipped with mounting flanges at both ends. This facilitates the installation and removal of the spray assembly from the exhaust gas treatment equipment.

[0012] Preferably, the sprinkler branch pipes are connected to the sprinkler main pipe via threads, which facilitates later maintenance and replacement of parts.

[0013] Preferably, the water inlet trough is located at the center of the top of the trumpet-shaped spray guide hood, and the outer side of the water inlet trough is fixedly connected to the inner side of the top opening of the trumpet-shaped spray guide hood.

[0014] Preferably, there are 3-4 narrow-angle fan-shaped nozzles, and the water inlet tank is provided with threaded connection ports arranged in a ring at equal intervals to seal and connect with the threaded interface on the narrow-angle fan-shaped nozzle.

[0015] Preferably, an installation rod is provided at the center of the water inlet tank, and the installation rod is threadedly connected to the internally threaded sleeve welded to the inner wall of the spray branch pipe.

[0016] Preferably, a circular through hole is provided at the bottom end of the spray branch pipe, and the upper outer side of the horn-shaped spray guide cover is positioned near the edge of the circular through hole.

[0017] Compared with the prior art, the technical effects and advantages of this utility model are:

[0018] 1. The pollution control sprayer has multiple narrow-angle fan-shaped nozzles arranged in a ring at equal intervals to form a relatively complete spray coverage area in the horizontal direction; the trumpet-shaped spray guide hood guides the trumpet-shaped spray water to expand the spray range in the vertical direction, so that the absorbent liquid can better cover the entire waste gas treatment space, increase the contact area between waste gas and absorbent liquid, and improve the waste gas treatment effect.

[0019] 2. The narrow-angle fan-shaped nozzle sprays the absorbent liquid in a fan shape, forming a concentrated spray area within a certain distance. The combination of multiple nozzles further enhances the spraying effect, allowing the exhaust gas to come into more full contact with the absorbent liquid and effectively remove harmful substances from the exhaust gas.

[0020] 3. The spray head, consisting of a trumpet-shaped spray guide hood and a narrow-angle fan-shaped nozzle, has a large spray area, which can reduce the number of spray heads on the spray branch pipe, thereby reducing equipment costs and installation complexity.

[0021] 4. The mounting flanges at both ends of the spray pipe simplify the installation of the spray assembly and the exhaust gas treatment equipment. Simply align the flanges and tighten them with bolts, which greatly shortens the installation time and improves work efficiency.

[0022] 5. The spray branch pipes and the main spray pipe are connected by threads, which facilitates disassembly.

Detailed Implementation

[0029] 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.

[0030] The following combination Figures 1 to 5 This application will be described in further detail.

[0031] This application discloses a pollution control sprayer, including an inlet pipe 1, a main spray pipe 2, a branch spray pipe 3, and spray heads 4. The inlet pipe 1 is connected to the main spray pipe 2. The branch spray pipes 3 are evenly distributed on both sides of the main spray pipe 2 and are connected to the main spray pipe 2. The spray heads 4 are evenly distributed and installed at the bottom of the branch spray pipes 3.

[0032] The main spray pipe 2 is equipped with a flow regulating valve 5 for adjusting the flow rate of the absorbent entering the spray branch pipe 3. The flow regulating valve 5 can flexibly adjust the flow rate of the absorbent entering the spray branch pipe 3 according to the actual waste gas treatment requirements. Different types and concentrations of waste gas may require different amounts of absorbent to achieve the best treatment effect. By adjusting the flow rate, precise matching can be achieved, improving the efficiency and quality of waste gas treatment.

[0033] A pressure sensor is also installed on the spray branch pipe 3. The pressure sensor is electrically connected to the controller of the pollution control system, and the controller is electrically connected to the flow regulating valve 5. When the pressure sensor detects an abnormal pressure in the spray branch pipe 3, the controller controls the flow regulating valve 5 to adjust the flow rate to ensure stable spray pressure. Stable spray pressure helps ensure that the absorbent liquid sprayed from the spray head 4 is uniform and covers a stable area, avoiding problems such as uneven spraying or poor local treatment effect caused by pressure fluctuations.

[0034] The spray main pipe 2 is equipped with mounting flanges 6 at both ends for easy installation and disassembly of the spray components and exhaust gas treatment equipment. During installation, simply align the flanges and tighten them with bolts, greatly shortening the installation time and improving work efficiency.

[0035] The spray branch pipe 3 is connected to the spray main pipe 2 by a thread, which facilitates later maintenance and replacement of parts. When a spray branch pipe 3 or spray head 4 malfunctions, it can be easily disassembled for repair or replacement without the need for large-scale disassembly and reinstallation of the entire spray assembly, thus reducing maintenance costs and downtime.

[0036] The spray head 4 includes a funnel-shaped spray guide shroud 42 with a water inlet trough 41 and a plurality of narrow-angle fan-shaped nozzles 43 arranged in a ring at equal intervals inside the funnel-shaped spray guide shroud 42 and connected to the water inlet trough 41.

[0037] Multiple narrow-angle fan-shaped nozzles 43 are arranged in a ring at equal intervals, forming a relatively complete spray coverage area in the horizontal direction. Compared with a single nozzle, the ring-shaped arrangement of nozzles allows the absorbent liquid to be more widely distributed in the waste gas treatment space, increasing the contact area between the waste gas and the absorbent liquid, thereby improving the waste gas treatment effect.

[0038] The narrow-angle fan-shaped nozzle 43 can spray the absorbent liquid in a fan shape. This spraying method can form a relatively concentrated spray area of ​​absorbent liquid within a certain distance, improving the impact and penetration of absorbent liquid. After multiple narrow-angle fan-shaped nozzles 43 are combined in a ring, the fan-shaped spray areas in different directions intertwine, further enhancing the spraying effect and allowing the exhaust gas to come into more complete contact with the absorbent liquid.

[0039] The trumpet-shaped spray guide hood 42 is located outside the narrow-angle fan-shaped nozzle 43, guiding the absorbent liquid sprayed from the nozzle 43 to form a trumpet-shaped spray. This spray shape expands the spray range vertically, allowing the absorbent liquid to better cover the entire waste gas treatment space. Especially for taller or wider treatment areas, the trumpet-shaped spray can more effectively deliver the absorbent liquid to every corner. The trumpet-shaped spray guide hood 42 also provides some protection, preventing the absorbent liquid from splashing in all directions during spraying. It guides the spray direction of the absorbent liquid to the area of ​​waste gas that needs treatment, reducing waste and preventing contamination and damage caused by the absorbent liquid splashing onto the outside of the equipment.

[0040] Moreover, the spray head 4, which consists of a horn-shaped spray guide hood 42 and a narrow-angle fan-shaped nozzle 43, has a large spray area, which can reduce the number of spray heads 4 on the spray branch pipe 3.

[0041] The water inlet trough 41 is located at the center of the top of the trumpet-shaped spray guide hood 42, and the outer side of the water inlet trough 41 is fixedly connected to the inner side of the top opening of the trumpet-shaped spray guide hood 42. This ensures that the absorbent liquid is evenly distributed into each narrow-angle fan-shaped nozzle 43. This design guarantees that each nozzle can obtain a stable flow rate and pressure, thereby making the spraying effect of the entire spray head 4 more uniform and consistent.

[0042] Three to four narrow-angle fan-shaped nozzles 43 are provided, and threaded connection ports 45 are arranged in a ring at equal intervals on the water inlet tank 41 to seal with the threaded interface 44 on the narrow-angle fan-shaped nozzles 43. This effectively prevents the absorbent liquid from leaking at the connection points, ensuring the sealing and reliability of the entire spray system.

[0043] A mounting rod 46 is located at the center of the water inlet tank 41. The mounting rod 46 is threadedly connected to the internally threaded sleeve 31 welded to the inner wall of the spray branch pipe 3. This provides a stable mounting structure for the spray head 4. This connection method not only ensures the stability of the spray head 4 during operation, but also facilitates disassembly and replacement when needed.

[0044] A circular through hole 32 is provided at the bottom end of the spray branch pipe 3, and the upper outer side of the trumpet-shaped spray guide shroud 42 is positioned near the edge of the circular through hole 32. This design helps to accurately install the spray head 4, ensuring that the position and angle of the spray head 4 meet the design requirements, thereby achieving the best spraying effect.

[0045] The pollution control sprayer operates based on liquid flow, pressure control, and a specific spray structure design to achieve efficient waste gas treatment, as detailed below:

[0046] Absorbent liquid delivery: The absorbent liquid enters the main spray pipe 2 through the inlet pipe 1. The main spray pipe 2 serves as the main liquid delivery channel, distributing the absorbent liquid to the spray branch pipes 3 that are evenly distributed on both sides.

[0047] Flow regulation: The flow regulation valve 5 installed on the main spray pipe 2 flexibly adjusts the flow rate of the absorbent entering the branch spray pipe 3 according to the actual waste gas treatment requirements. Different types and concentrations of waste gas require different amounts of absorbent, and the flow regulation valve 5 can achieve precise matching.

[0048] Pressure monitoring and control: The pressure sensor on the spray branch pipe 3 monitors the pressure inside the pipe in real time and transmits the pressure data to the controller of the pollution control system. When an abnormal pressure is detected, the controller issues a command to control the flow regulating valve 5 to adjust the flow rate of the absorbent liquid, thereby ensuring stable spray pressure.

[0049] Spray head 4 operation: The absorbent liquid reaches the spray head 4 installed at the bottom through the spray branch pipe 3. In the spray head 4, the absorbent liquid first enters the water inlet tank 41. Since the water inlet tank 41 is located at the top center of the trumpet-shaped spray guide shroud 42 and is connected to the narrow-angle fan-shaped nozzles 43, the absorbent liquid is evenly distributed into 3-4 narrow-angle fan-shaped nozzles 43 arranged in a ring at equal intervals. The narrow-angle fan-shaped nozzles 43 spray the absorbent liquid out in a fan shape, and the fan-shaped spray areas of multiple nozzles interweave with each other. At the same time, the trumpet-shaped spray guide shroud 42 guides these absorbent liquids to form a spray of water with a trumpet-shaped opening, expanding the spray range.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
