Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification, in particular to a layered desulfurization tower. Background Art

[0002] A desulfurization tower is a device used to remove sulfur dioxide (SO2) from flue gas. Flue gas purification in a desulfurization tower refers to using the desulfurization tower equipment to remove or convert sulfur dioxide (SO2) in the flue gas, so as to reduce the harmful effects on the environment and human health. It is mainly used in the industrial production process, especially in industries such as coal-fired power plants, oil refineries, and metal smelting. The flue gas generated during the process of burning coal, etc. contains sulfur dioxide, which is a gas harmful to the environment and human health. The desulfurization tower converts sulfur dioxide into other substances through absorption, adsorption, or oxidation to reduce its emissions.

[0003] According to the publication number: CN216457999U, a layered spray desulfurization tower includes a desulfurization tower body. In this layered spray desulfurization tower, by arranging a liquid accumulation plate inside the desulfurization tower and a number of liquid accumulation grooves on the surface of the liquid accumulation plate, first, the flue gas can be evenly filtered through the filter screen on the surface of the liquid accumulation groove, and then the atomized desulfurization liquid and the flue gas are fully and evenly mixed in the liquid accumulation groove, and then slurry bubbles are generated to continue to adsorb and filter the sulfur-containing substances in the flue gas, extending the contact time and area between the desulfurization liquid and the flue gas, thereby greatly improving the flue gas treatment effect of this desulfurization tower; however, the existing desulfurization towers still have the following defects in the actual use process:

[0004] 1. Most of the existing desulfurization towers use the flow of gas inside the pipeline for operation, resulting in a slow flow rate of the gas to be treated, reducing the efficiency. The slow flow rate will limit the treatment capacity of the desulfurization tower, thereby affecting the treatment capacity and treatment efficiency of the desulfurization tower.

[0005] 2. During the entire process of the desulfurization tower, usually, the desulfurization tower filters and circulates the water through the internal filtering structure. However, when too much filter accumulates, it is necessary to clean and discharge the filter more frequently, which is not convenient for the long-term operation of the desulfurization tower.

[0006] Therefore, we propose a layered desulfurization tower to solve the above drawbacks. Content of the Utility Model

[0007] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a layered desulfurization tower is proposed.

[0037] Preferably, the water pump output spray pipe comprises:

[0038] Spray nozzles, which are all connected to the other end of the water pump output spray pipe;

[0039] A plate demister, which is installed on the surface of the wire mesh filter plate;

[0041] Preferably, the controller further comprises:

[0043] The fan blades are located at the bottom of the waterproof housing;

[0044] The controller is electrically connected to the storage battery, the motor and the circulating water pump respectively.

[0045] Compared with the prior art, the beneficial effects of the present utility model are as follows: By driving the rotation of the fan blades by the motor, the gas flow velocity is increased to improve the processing capacity and efficiency of the desulfurization tower. Through the circulating water pump and the spray nozzles for spraying, the sprayed water is used to wash the filter to the waste box, and is filtered and collected by the vertical filter plate, thereby reducing the frequency of cleaning the filter, increasing the continuous operation time of the desulfurization tower, and improving the operation efficiency.

[0046] (1). In the present utility model, the motor and the fan blades are adopted. In order to reduce the problem that the processing capacity and efficiency of the desulfurization tower are affected due to the slow gas flow velocity, when the user uses the desulfurization tower for operation, the motor connected by electricity is started through the controller. By starting the motor, the connected first bevel gear is driven to rotate, so that the engaged second bevel gear drives the rotating shaft to rotate, so that the fan blades installed at the other end of the rotating shaft rotate, so that the gas flow velocity inside is increased. By increasing the gas flow velocity, the processing capacity of the desulfurization tower can be improved. The operation of the motor and the fan blades is realized through mechanical transmission to increase the gas flow velocity, thereby improving the performance of the desulfurization tower, and thus reducing the influence problem of the slow gas flow velocity on the processing capacity and efficiency of the desulfurization tower.

[0047] (2) This utility model adopts a waste bin and a vertical filter plate. In order to reduce the need for frequent cleaning and discharging of the filter, and increase the operation time of the desulfurization tower, during the operation of the desulfurization tower by the user, the spray head performs the operation of purifying the flue gas through the connection of the circulating water pump and the pipeline, so that the sprayed water falls onto the surface of the inclined filter plate at the bottom and the inside of the waste bin. The filter flows into the inside of the waste bin through the inclined filter plate, and is filtered by the vertical filter plate on the side of the waste bin, so that the filter is stored inside the waste bin. The frequency of cleaning the filter can be reduced because the sprayed water will wash the filter into the waste bin and further filter and collect it through the vertical filter plate. This can increase the continuous operation time of the desulfurization tower, reduce the shutdown and cleaning time, and improve the overall operation efficiency. Description of the Drawings

[0054] To make the purpose, technical solutions and advantages of the present utility model clearer, the following will further elaborate on the present utility model in combination with the specific embodiments and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present utility model.

[0055] Embodiment: As Figure 1As shown in the figure, a layered desulfurization tower includes: The desulfurization tower shell 1 is the main structure of the desulfurization tower, which plays a role in enclosing and protecting other components. By preventing the leakage of harmful substances, it ensures that the desulfurization process can be carried out in a controlled environment. The intake pipe 2 is used to introduce the flue gas to be treated into the desulfurization tower for subsequent treatment processes. The controller 3 is used to control the operation and parameter settings of the desulfurization tower. It can monitor the status of each component and adjust the operation mode of the desulfurization tower as needed. The storage battery 4 is used to provide power supply for the controller and other electronic devices. The waste bin 5 is set on the side of the desulfurization tower shell, mainly used for collecting and storing the filtered waste. It can accommodate a large amount of waste, reduce the frequency of shutdown and cleaning processes, and thus improve the continuous operation time of the desulfurization tower. The handle 6 facilitates the operator to move and handle the waste. The exhaust pipe 7 is used to discharge the treated flue gas out of the desulfurization tower.

[0056] As Figure 2 shown in the figure, it includes: The inclined filter plate 8 is installed inside the desulfurization tower shell. Its inclined design is beneficial to filtering and collecting waste. It can let the filtered substances flow into the inside of the waste bin, facilitating subsequent treatment. The vertical filter plate 9 is used to further filter and collect waste. It provides a filtering layer to enhance the filtering effect and intercept the filtered substances inside the waste bin 5. The water pump inlet pipe 10 is used to introduce circulating water into the desulfurization tower. The water pump inlet pipe ensures that the circulating water can be effectively supplied to the desulfurization tower for washing and spraying processes. The water pump outlet spraying pipe 11 is used to spray the circulating water and desulfurizing agent mixture into the desulfurization tower. It evenly sprays the circulating water and desulfurizing agent onto the harmful substances to achieve the purpose of flue gas purification. The spray head 12 is used to evenly spray the spraying fluid into the desulfurization tower. The spray head can ensure that the spraying fluid evenly covers the entire treatment area, ensuring sufficient contact between the desulfurizing agent and the flue gas. Multiple layers are provided for layered spraying operations to increase the treatment effect. The plate demister 13 and the wire mesh filter plate 14 are used to filter and collect the particulate matter and water mist in the flue gas. They can capture and filter out smaller particles and moisture, improving the purification effect of the flue gas.

[0057] As Figure 3As shown in the figure, it includes: The motor 15 is installed on the side of the desulfurization tower shell and drives the operation of other components through rotation. It provides power to drive the fan blades, increasing the gas flow rate, thereby improving the processing capacity of the desulfurization tower. The first bevel gear 16 drives the operation of the connected bevel gear through its rotation. The rotating shaft 17 drives the operation of the connected components through rotation. It plays a role in transmitting power and supporting other components, enabling the relevant components to work together. The waterproof housing 18 plays a role in waterproofing and protecting the internal components such as the bevel gear. It ensures that water and other liquids do not penetrate into the interior of the desulfurization tower, thereby protecting the normal operation of the internal mechanical and electronic equipment. The second bevel gear 19 drives the rotation of the rotating shaft through meshing with the first bevel gear. It is a bridge for transmitting rotational energy, enabling the rotating shaft and the fan blades to operate. The fan blades 20 generate an air flow through the rotation of the rotating shaft, increasing the gas flow rate, playing a role in accelerating and enhancing the flow, maintaining the gas convection and circulation inside the desulfurization tower to improve the processing efficiency. The circulation water pump 21 is used for circulating and supplying water and desulfurizing agent. It sends water and desulfurizing agent into the spraying system through pumping action to provide the necessary liquid.

[0058] In this implementation scheme: The control panel control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the art. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0059] Working principle: First, in order to reduce the problem that the slow gas flow rate affects the treatment capacity and efficiency of the desulfurization tower, when the user operates the desulfurization tower, the motor 15 electrically connected is started through the controller 3. The rotation of the motor 15 drives the connected first bevel gear 16 to rotate, causing the engaged second bevel gear 19 to drive the rotating shaft 17 to rotate, and the fan blade 20 installed at the other end of the rotating shaft 17 to rotate, increasing the gas flow rate inside. By increasing the gas flow rate, the treatment capacity of the desulfurization tower can be improved. The operation of the motor and the fan blade is achieved through mechanical transmission to increase the gas flow rate, thereby improving the performance of the desulfurization tower, and reducing the impact of slow gas flow rate on the treatment capacity and efficiency of the desulfurization tower. In order to reduce the need for frequent cleaning and discharging of the filter, and increase the operation time of the desulfurization tower, during the operation of the desulfurization tower by the user, the spray head 12 performs the operation of purifying the flue gas through the connection of the circulating water pump 21 and the pipeline. The sprayed water drops onto the surface of the inclined filter plate 8 at the bottom and the inside of the waste box 5. Through the inclined filter plate 8, the filter flows into the inside of the waste box 5, and is filtered by the vertical filter plate 9 on the side of the waste box 5, so that the filter is stored inside the waste box 5. The frequency of cleaning the filter can be reduced because the sprayed water will wash the filter into the waste box 5 and further filter and collect it through the vertical filter plate 9. This can increase the continuous operation time of the desulfurization tower, reduce the downtime and cleaning time, and improve the overall operation efficiency.
