Description

Technical Field

[0001] This utility model relates to the field of industrial plant exhaust treatment technology, and more specifically, to a self-circulating acid mist spraying tower for industrial plants. Background Technology

[0002] During summer processing, the temperature in industrial plants rises, which can affect the work efficiency of employees. Therefore, in order to provide a comfortable environment, ventilation is carried out inside the plant to expel hot air, reduce the temperature inside the plant, and provide a comfortable environment for employees to continue working inside the plant.

[0003] Chinese patent CN206420105U discloses an automatic humidity and temperature control device for a fresh air system in an industrial plant. The device has an air inlet duct installed inside the wall and an exhaust fan installed on one side of the wall to achieve the functions of introducing fresh air and expelling stale air. An air conditioner and a humidifier are installed on the side of the air inlet duct. The device automatically controls the indoor temperature and humidity by setting temperature and humidity parameters using a controller. The controller integrates a temperature and humidity display, a temperature and humidity setpoint display, and adjustment buttons.

[0004] While this patent can ventilate and lower the temperature of industrial plants, it also exhausts the internal air of the plants during ventilation. The operation of machinery in the plants generates a certain amount of waste gas, such as acidic waste gas and hydrochloric acid waste gas. Of course, the concentration of acidic gas is less than the hazardous concentration to ensure the safety of workers. However, if these waste gases are directly discharged into the air, they will pollute the atmosphere. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a factory self-circulating acid mist spraying tower that overcomes or at least partially solves the above technical problems.

[0006] This utility model is implemented as follows:

[0007] This utility model provides a self-circulating acid mist spraying tower for factory buildings, including an installation frame, in which a fan is fixedly installed, and a spraying mechanism is connected to the fan's exhaust port through a duct.

[0008] The spraying mechanism includes:

[0009] The tower body is sealed to the exhaust port of the fan via a duct, and the spray pipe is fixedly installed inside the tower body.

[0018] In a preferred embodiment, an exhaust channel is provided at the top of the tower body.

[0019] The present invention provides a self-circulating acid mist spraying tower for factory buildings, the beneficial effects of which include:

[0020] 1. By installing baffles inside the tower body and delivering gas to the area below the baffles, and by installing air outlets on the baffles and gas delivery pipes at the outlets, the air drawn into the tower body will enter the gas delivery pipes. The gas delivery pipes are installed inside the tower body in a bent shape, which can extend the air flow distance and slow down the air flow rate inside the tower, thereby improving the air treatment effect, removing acidic waste gas from the air, and avoiding pollution to the atmosphere.

By controlling the rotation of the eccentric wheel, the connecting rod is pushed to move up and down. When the connecting rod moves upward, it can rotate the baffle to a horizontal state, increasing the ventilation volume from the baffle position. Conversely, it will reduce the ventilation volume. By controlling the air volume, the temperature inside the industrial plant is regulated. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0030] Reference Figures 1-5 This utility model provides a technical solution: a self-circulating acid mist spraying tower for a factory, including an installation frame 1. A fan 2 is fixedly installed inside the installation frame 1, and a spraying mechanism 4 is connected to the exhaust port of the fan 2 via a duct. The spraying mechanism 4 includes a tower body 41, which is located outside the installation frame 1. In actual use, the tower body 41 is also located outside the factory. The tower body 41 is sealed to the exhaust port of the fan 2 via a duct, which is positioned between the fan 2 and the tower body 41. The fan 2 draws air from the factory and transports it from inside the duct to the inside of the tower body 41 for air treatment. Spray pipes 411 are fixedly installed inside the tower body 41. Two sets of spray pipes 411 are arranged vertically, which can improve the treatment effect of waste gas, increase the full reaction between waste gas and spray liquid, and remove acidic gases from the waste gas. By fixing the baffle 42 to the lower end inside the tower body 41, the baffle 42 can concentrate the exhaust gas entering the tower body 41 below the baffle 42. An exhaust hole 421 is opened on the upper surface of the baffle 42, and a gas supply pipe 422 is fixedly connected at the position of the exhaust hole 421. A small exhaust hole 43 is opened on the outer surface of the gas supply pipe 422. The gas below the baffle 42 can only move upward through the position of the exhaust hole 421. At this time, the exhaust gas will move inside the gas supply pipe 422. Adding a gas supply pipe 422 inside the tower body 41 can extend the distance the exhaust gas moves and increase the reaction time between the exhaust gas and the spray liquid, so that the acidic substances in the exhaust gas can react fully with the spray liquid, ensuring the removal of acidic substances in the exhaust gas and avoiding pollution to the atmosphere.

[0031] Reference Figures 1-5 In a preferred embodiment, an airflow control mechanism 3 is provided in front of the fan 2. The airflow control mechanism 3 includes a connecting rod 31, which is stably moved up and down inside the mounting frame 1 by a limiting ring. The outer side of the connecting rod 31 is rotatably connected to the branch plate 311 by a rotating shaft. The airflow control mechanism 3 also includes a baffle plate 32, which is rotatably installed inside the mounting frame 1 by a long shaft. The baffle plate 32 is movably connected to the branch plate 311. By setting two connecting rods 31 inside the mounting frame 1, both of which are vertically set, and by rotatably installing the branch plates 311 on the outer side of the connecting rods 31, a plurality of branch plates 311 are provided and evenly distributed on the opposite sides of the two connecting rods 31. Every two branch plates 311 are rotatably connected to a baffle plate 32. The rotation of the branch plates 311 can control the rotation of the baffle plate 32, thereby adjusting the airflow.

[0032] Reference Figures 1-5In a preferred embodiment, the airflow control mechanism 3 further includes a drive rod 33, which is rotatably mounted at the bottom of the mounting frame 1. An eccentric wheel 331 for pushing the connecting rod 31 to move up and down is fixedly mounted on the drive rod 33. The airflow control mechanism 3 also includes a servo motor 34, which is fixedly mounted inside the mounting frame 1. The output end of the servo motor 34 is fixedly mounted on the drive rod 33. This configuration facilitates the control of the rotation of the baffle 32. The servo motor 34 is installed inside the mounting frame 1. The drive rod 33 can be rotated by the servo motor 34, which in turn drives the eccentric wheel 331 to rotate. Due to the characteristics of the eccentric wheel 331, the connecting rod 31 can be pushed to move up and down, thereby achieving the rotation of the baffle 32. There are two eccentric wheels 331, both mounted on one drive rod 33. The two eccentric wheels 331 can be controlled to rotate simultaneously by one servo motor 34, which meets the usage requirements.

[0033] By fixing the gas supply pipe 422 inside the tower body 41 in a bent shape and setting the small exhaust port 43 at the horizontal end of the gas supply pipe 422, when the exhaust gas moves inside the gas supply pipe 422, some of the gas will be discharged from the small exhaust port 43 and enter the interior of the tower body 41. This avoids a large amount of exhaust gas moving upward inside the tower body 41 at once, which may lead to insufficient reaction of the exhaust gas. This equipment uses this method to transport and discharge exhaust gas, which can make the exhaust gas react fully with the spray liquid and improve the treatment effect of exhaust gas.

[0034] The equipment has a water pump 5 installed outside the tower body 41. The outlet and inlet of the water pump 5 are tightly connected to the pipe 6. The pipe 6 at the outlet of the water pump 5 is connected to the spray pipe 411. The water pump 5 draws the spray liquid from the outside and delivers it to the inside of the spray pipe 411. Then it is sprayed out from the inside of the spray pipe 411 in a cone shape, which can expand the spray area and allow the exhaust gas at any position of the tower body 41 to participate in the reaction.

[0035] An exhaust channel 7 is provided at the top of the tower body 41.

[0036] Specifically, the working process or working principle of a self-circulating acid mist spraying tower for industrial plants is as follows: This equipment can spray and treat the gas discharged from industrial plants to remove acidic waste gas and avoid direct emission, which would pollute the atmosphere.

[0037] In practical use, the equipment is installed at the window of the factory building, and the mounting frame 1 is installed on the wall with expansion screws. Then it is connected to the external power supply. When ventilation is required, the fan 2 is turned on. The fan blades on the fan 2 rotate continuously, which can draw the air inside the factory building into the air duct. In order to prevent particles mixed in the exhaust gas in the factory building from entering the exhaust gas treatment tower 41, a filter screen 8 is installed on the outside of the fan 2. The filter screen 8 can filter the particles in the air.

[0038] The air drawn in by the fan 2 then enters the tower body 41 through the duct. The air enters the bottom of the tower body 41 and then rises. It passes through the partition 42 and enters the air supply pipe 422. The air moves upward inside the air supply pipe 422 and passes through the small exhaust hole 43. Some of the air is discharged from the small exhaust hole 43 and enters the tower body 41. At the same time, the water pump 5 draws in the treatment liquid from the outside and transports it to the spray pipe 411 through the pipe 6. The bottom of the spray pipe 411 is equipped with a water outlet, and the treatment liquid can be sprayed out from the inside of the spray pipe 411 to spray the exhaust gas inside the tower body 41, thereby treating the exhaust gas.

[0039] When using this equipment, the exhaust air volume can be adjusted according to the actual situation to maintain a suitable temperature in the industrial plant. The rotation of the servo motor 34 controls the rotation of the drive rod 33. When it is necessary to increase the exhaust speed and volume, the rotation of the drive rod 33 will drive the eccentric wheel 331 to rotate. When the high end of the eccentric wheel 331 pushes the connecting rod 31 upward, it can drive the branch plate 311 to rotate, opening the baffle plate 32 to the maximum. At this time, the air can be quickly discharged from the gap between the baffle plates 32 and enter the interior of the tower body 41.

[0040] Conversely, when the temperature inside the factory is not too high, the exhaust speed of the factory air can be slowed down to avoid the factory temperature being too low and making the staff feel cold. Similarly, by working through the servo motor 34, the lower end of the eccentric wheel 331 is controlled to contact the connecting rod 31, the connecting rod 31 will move downward and drive the baffle plate 32 to rotate, so that the baffle plate 32 is in an inclined state, reducing the speed of air passing through the baffle plate 32. By adjusting the air volume, the temperature inside the factory can be regulated.
