Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and specifically relates to a waste gas treatment device for environmental protection. Background Technology

[0002] With the acceleration of industrialization and the improvement of urbanization, the total amount of waste gas emissions is constantly increasing, and the composition of waste gas is becoming increasingly complex, containing various harmful gases such as sulfur dioxide, nitrogen oxides, and volatile organic compounds (VOCs). If these waste gases are directly emitted into the atmosphere without effective treatment, they will cause a series of environmental problems such as acid rain and smog, seriously harming ecosystems and human health. Therefore, the development of efficient waste gas treatment devices is crucial for environmental protection.

[0003] In practical applications, waste gas treatment devices come in various types and operating modes. Common types include adsorption-type waste gas treatment devices, which utilize adsorbents such as activated carbon to adsorb pollutants in the waste gas, thereby purifying it. During operation, the waste gas passes through an adsorption bed filled with adsorbent, and the pollutants are adsorbed onto the surface of the adsorbent. Another type is catalytic combustion-type waste gas treatment devices, which, under the action of a catalyst, oxidize and burn the combustible components in the waste gas at a lower temperature, converting them into harmless substances such as carbon dioxide and water. In use, the waste gas is preheated before entering a reactor containing a catalyst for combustion. Finally, spray scrubbing-type waste gas treatment devices remove pollutants by spraying liquid (such as water or a specific scrubbing solution) onto the waste gas, causing the pollutants to come into contact with the liquid and undergo physical or chemical reactions.

[0004] Current spray scrubbing type exhaust gas treatment devices generally introduce exhaust gas into a spray chamber, where the spray scrubbing liquid washes away solid particles in the exhaust gas and reacts with chemical gases. However, during the spraying process, the gas-liquid contact area and contact time are limited, making it difficult to ensure that all exhaust gas pollutants can fully contact and react with the scrubbing liquid, thus affecting the treatment effect. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide an environmental protection waste gas treatment device. This addresses the shortcomings of current spray scrubbing type waste gas treatment devices, which typically involve introducing waste gas into a spray chamber where the scrubbing liquid washes away solid particles and reacts with chemical gases. However, during the spraying process, the gas-liquid contact area and contact time are limited, making it difficult to ensure that all waste gas pollutants can fully contact and react with the scrubbing liquid, thus affecting the treatment effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an environmental protection waste gas treatment device, comprising a tower body, a support base fixedly installed on the lower side of the tower body, a smoke inlet connected to the upper side of the tower body, a spray ring fixedly installed on the upper inner side of the tower body, a water inlet fixedly installed at the upper end of the tower body, the water inlet penetrating into the inner side of the tower body and communicating with the spray ring, spray heads equidistantly arranged around the lower side of the spray ring, a large fan fixedly installed at the center of the spray ring on the upper inner side of the tower body, the output end of the large fan facing downwards, the input end of the large fan penetrating into the upper side of the tower body, oscillating rings equidistantly fixed in the middle inner side of the tower body, and an exhaust pipe fixedly connected to one side of the lower side of the tower body.

[0007] The beneficial effects of this utility model are as follows: The large fan is set in the center of the spray ring with the output end facing downward. The high-speed airflow generated by its operation can quickly drive and cut the spray liquid, so that the spray liquid and the exhaust gas entering from the flue gas inlet and undergoing reasonable diffusion can be fully mixed, which greatly increases the gas-liquid contact area. The oscillating rings fixed at equal intervals in the middle of the inner side of the tower body cause airflow turbulence when the exhaust gas and spray liquid pass through, which drives the exhaust gas and spray liquid droplets to further oscillate, effectively improving the exhaust gas treatment effect.

[0008] To facilitate the rapid and uniform diffusion of exhaust gas within the tower;

[0009] As a further improvement to the above technical solution: a smoke outlet ring is fixedly provided on the inner side of the tower body corresponding to the smoke inlet, the smoke outlet ring is connected to the smoke inlet, and smoke outlet holes are evenly opened on the inner side of the smoke outlet ring.

[0010] The beneficial effects of this improvement are: the smoke outlet ring is connected to the smoke inlet and the smoke outlet holes are evenly opened on the inner side, which allows the waste gas entering the tower to be discharged evenly through the smoke outlet holes, which facilitates the rapid and even diffusion of the waste gas in the tower, and is conducive to the full contact and reaction between the waste gas and the spray liquid, thereby improving the treatment efficiency.

[0011] To avoid liquid buildup;

[0012] As a further improvement to the above technical solution: all the oscillation rings are inclined downwards towards the center.

[0013] The beneficial effect of this improvement is that it avoids the accumulation of liquid.

[0014] To facilitate the collection and treatment of waste liquid generated during the process;

[0015] As a further improvement to the above technical solution: a flow collector is fixedly connected to the bottom center of the tower body, and a control valve is fixedly connected to the lower side of the flow collector.

[0016] The beneficial effects of this improvement are: the collection bucket can gather the waste liquid at the bottom of the tower, and the control valve is used to control the centralized discharge of the waste liquid, which facilitates the collection and treatment of the waste liquid generated during the process.

[0017] To allow the liquid to flow back to the bottom of the tower body;

[0018] As a further improvement to the above technical solution: the exhaust pipe extends vertically upward to the vicinity of the smoke inlet, a fixing ring is fixedly installed between the exhaust pipe and the tower body, and liquid collection plates are fixedly installed at equal intervals in the middle of the inner side of the exhaust pipe.

[0019] The beneficial effects of this improvement are as follows: the exhaust pipe extends vertically upward to the vicinity of the flue gas inlet and is equipped with a fixing ring, which increases the stability of the exhaust pipe; the liquid collection plates arranged at equal intervals inside the exhaust pipe can intercept and condense a small amount of fine liquid droplets carried in the exhaust gas, allowing them to flow back to the bottom of the tower body.

[0020] To allow manual access to the tower's interior for cleaning and maintenance;

[0021] As a further improvement to the above technical solution: manholes are provided on both the upper and lower sides of the tower body, and a sealing cover is provided at the input of the manhole with bolts for sealing.

[0022] The beneficial effects of this improvement are: manholes are opened on the upper and lower sides of the tower body and sealed covers are installed, which facilitates the periodic opening of the sealed covers and manual entry into the tower body for cleaning and maintenance, ensuring the long-term stable operation of the device.

[0023] In summary, the beneficial effects of this technical solution are as follows: the exhaust ring uniformly diffuses the exhaust gas, the large fan accelerates gas-liquid mixing, the swirling ring enhances the mixing effect, the liquid collection plate reduces waste liquid emissions with the exhaust gas, the confluence bucket and control valve facilitate waste liquid treatment, and the manhole facilitates maintenance, which significantly improves the exhaust gas treatment effect. At the same time, it takes into account waste liquid treatment, resource utilization and equipment maintenance, and has high practicality and environmental benefits.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0030] like Figure 1 — Figure 3As shown: An environmental protection waste gas treatment device includes a tower body 1. A support base 8 is fixedly installed on the lower side of the tower body 1. A smoke inlet 2 is connected to the upper side of the tower body 1. A spray ring 4 is fixedly installed on the upper inner side of the tower body 1. A water inlet 3 is fixedly installed at the upper end of the tower body 1, penetrating into the inner side of the tower body 1 and communicating with the spray ring 4. Spray heads are equidistantly arranged around the lower side of the spray ring 4. A large fan 5 is fixedly installed at the center of the spray ring 4 on the upper inner side of the tower body 1. The output end of the large fan 5 faces downward, and the input end of the large fan 5 penetrates into the upper side of the tower body 1. Oscillation rings 6 are equidistantly fixed in the middle of the inner side of the tower body 1. An exhaust pipe 11 is fixedly connected to one side of the lower side of the tower body 1. A large fan is located at the center of the spray ring with its output end facing downwards. The high-speed airflow generated by the fan can quickly drive and break up the spray liquid, allowing the spray liquid to fully mix with the exhaust gas entering from the smoke inlet and undergoing proper diffusion. This greatly increases the gas-liquid contact area. The oscillating rings fixed at equal intervals in the middle of the inner side of the tower body cause airflow turbulence when the exhaust gas and spray liquid pass through, further agitating the exhaust gas and spray droplets, effectively improving the exhaust gas treatment effect. A smoke outlet ring 7 is fixedly installed on the inner side of the tower body 1 corresponding to the smoke inlet 2. The smoke outlet ring 7 is connected to the smoke inlet 2, and smoke outlet holes are evenly opened on the inner side of the smoke outlet ring 7. The tower body 1 has interconnected and uniformly spaced smoke outlets on its inner side, allowing the waste gas entering the tower to be discharged evenly through these outlets. This facilitates rapid and uniform diffusion of the waste gas within the tower, promoting thorough contact and reaction between the waste gas and the spray liquid, thus improving treatment efficiency. The oscillating rings 6 are all angled downwards towards the center to prevent liquid accumulation. A collection hopper 9 is fixedly connected to the center of the bottom of the tower body 1, and a control valve 10 is fixedly connected to the lower side of the collection hopper 9. The collection hopper gathers the waste liquid at the bottom of the tower body, while the control valve controls the centralized discharge of the waste liquid, facilitating the collection and treatment of waste liquid generated during the process. The exhaust pipe 11 extends vertically upwards to the vicinity of the smoke inlet 2. The exhaust pipe 11 and the tower body 1... A fixing ring 12 is fixedly installed between the exhaust pipes. Liquid collection plates 13 are fixedly installed at equal intervals in the middle of the inner side of the exhaust pipe 11. The exhaust pipe extends vertically upward to the vicinity of the smoke inlet and is fixed with a fixing ring, which increases the stability of the exhaust pipe. The liquid collection plates are installed at equal intervals in the exhaust pipe, which can intercept and condense a small amount of fine liquid droplets carried in the exhaust gas, allowing them to flow back to the bottom of the tower body. Manholes 14 are opened on the upper and lower sides of the tower body 1. A sealing cover 15 is bolted and sealed at the inlet of the manhole 14. The manholes and sealing covers on the upper and lower sides of the tower body facilitate the periodic opening of the sealing cover and the manual entry of the tower body through the manhole for cleaning and maintenance, ensuring the long-term stable operation of the device.

[0031] Working principle and usage process of this utility model:

[0032] In operation, this technical solution connects to the flue gas duct via the flue gas inlet 2 and the spray liquid input duct via the water inlet 3. The waste liquid discharge duct is connected via the control valve 10. Exhaust gas enters the inner side of the tower body 1 through the flue gas inlet 2 and is evenly discharged through the exhaust holes of the exhaust ring 7, facilitating rapid and uniform diffusion within the tower body 1. Simultaneously, the spray liquid enters the spray ring 4 through the water inlet 3 and is then sprayed from the spray head on the lower side of the spray ring 4. At the same time, the large fan 5 is activated, operating at high speed to generate airflow. This airflow rapidly carries and breaks up the spray liquid, causing it to quickly mix and react with the exhaust gas sprayed from the inner side of the exhaust ring 7. As the airflow passes between the oscillating rings 6, the turbulent airflow causes the exhaust gas and spray liquid droplets to vibrate, further enhancing the dispersion of the spray liquid. In addition to the mixing reaction, after the spray liquid is sprayed out through the spray head, it is driven by the high-speed airflow. Although the spray liquid is broken and dispersed, it is far from being atomized. Therefore, after the spray liquid mixes and reacts with the exhaust gas, it will fall to the bottom of the inner side of the tower body 1 and re-collect. After the exhaust gas is cleaned and reacted, it will be discharged from the exhaust pipe 11. The exhaust pipe 11 is connected to the exhaust gas discharge pipe. The exhaust gas entering the inner side of the exhaust pipe 11 will carry a small amount of fine liquid droplets. After being intercepted and condensed by the inner wall of the exhaust pipe 11 and the liquid collection plate 13, it will flow back to the bottom of the inner side of the tower body 1. After the waste liquid is collected by the confluence hopper 9, it can be discharged from the control valve 10. The sealing cover 15 is opened periodically, and manual cleaning and maintenance can be carried out through the manhole 14.
