Description

Technical Field

[0001] This utility model relates to the field of flue gas denitrification technology, and more specifically, to a low-temperature flue gas denitrification device. Background Technology

[0002] Flue gas typically contains large amounts of nitrogen oxides. If these nitrogen oxides are directly released into the atmosphere, they can cause highly corrosive acid rain. Therefore, flue gas must be denitrified before it is released to reduce the content of nitrogen oxides and minimize environmental damage.

[0003] The flue gas low-temperature denitrification device disclosed in application number CN202323586376.9 is also an increasingly mature technology. By increasing the atomizing nozzles on the left and right sides inside the denitrification box, the spraying range and density are increased. The atomizing nozzles make the sprayed denitrification liquid finer, which can better mix the flue gas and the denitrification liquid. The rotating motor drives the stirring fan to rotate, which makes the flue gas at the top of the denitrification box and the flue gas at the bottom of the denitrification box better form convection, which can better mix the flue gas and the denitrification liquid and improve the denitrification effect of the flue gas. The primary filter layer filters out large particles of dust and suspended matter. The high-efficiency filter layer filters out large particles of dust and suspended matter. The activated carbon layer effectively filters out harmful gases such as formaldehyde, benzene, and ammonia, as well as bacteria and heavy metals. The catalyst layer converts formaldehyde into harmless substances through catalytic decomposition. The enzyme-containing antibacterial filter layer effectively filters and intercepts bacteria and microorganisms. At the same time, the large amount of highly efficient natural lysozyme attached to the filter fibers efficiently dissolves the captured microorganisms and bacteria, achieving sterilization and preventing them from multiplying, thus preventing secondary pollution.

[0004] Based on this, we agree with the advantages of the aforementioned products, but the following drawbacks still exist:

[0005] This type of denitrification device is not convenient for subsequent cleaning of substances remaining in the flue gas, and the lack of temperature detection function may lead to untimely response and affect the overall operating efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a low-temperature flue gas denitrification device to solve the problems mentioned in the background art, such as inconvenience in subsequent cleaning and lack of temperature detection function.

[0007] This utility model provides a low-temperature flue gas denitrification device, including a denitrification chamber, wherein a denitrification device is installed inside the denitrification chamber;

[0008] The denitrification device includes a micro motor located at the top center of the denitrification chamber, with a fan blade connected to the output end of the micro motor. Inside the denitrification chamber, at the bottom end of the fan blade, is a support tube. Spray nozzles are evenly distributed at symmetrical intervals on the symmetrical ends of the support tube. One end of the support tube passes through one side of the denitrification chamber via a connecting pipe and is connected to the outlet of a water pump on the outside. The outside of the support tube is connected to the internal side wall of the denitrification chamber via support rods. Fiber filters and filter screens are movably installed at the bottom end of the support tube in the denitrification chamber.

[0009] In this embodiment, a water pump connects to the denitrification liquid, which is then pumped into the connecting pipe and support pipe and sprayed out through the nozzle. A micro motor drives the fan blades to rotate, which better mixes the flue gas and the denitrification liquid. The fiber filter can store the denitrification liquid, and the flue gas needs to pass through the fiber filter, which increases the contact between the flue gas and the denitrification liquid. The fiber filter is coated with lysozyme, which can achieve the purpose of sterilization. The filter is used to remove larger particulate matter in the flue gas.

[0010] In one embodiment of this utility model, the top of the denitrification chamber is provided with an exhaust port outside the micro motor and an exhaust pipe is connected to the top. The exhaust pipe is provided with a matching filter plate, activated carbon plate, catalyst plate and enzyme sterilization filter plate from bottom to top.

[0011] In this solution, four different plates are used inside the exhaust pipe. The filter plate is used to filter out large dust and suspended matter in the airflow. The activated carbon plate is used to filter harmful gases such as formaldehyde, benzene, and ammonia. The catalyst plate uses catalytic decomposition to convert formaldehyde into harmless substances. The enzyme sterilization filter plate is used to filter and intercept bacteria and microorganisms, reducing the risk of infection and disease transmission.

[0012] In one embodiment of this utility model, a heating plate is provided on the inner side wall of the denitrification chamber between the support tube and the fiber filter screen, and a temperature sensor is provided on the inner side wall of the denitrification chamber on the same side as the water pump.

[0013] In this scheme, a temperature sensor is used to detect internal temperature changes in real time, and a heating plate is used to maintain the optimal temperature required for the denitrification reaction, thereby improving the denitrification efficiency.

[0014] In one embodiment of this utility model, a drain pipe is provided in the middle of the bottom end of the denitrification box and a control valve is provided on the outside. An air inlet pipe is provided on the same side of the denitrification box and the water pump, located on the bottom end of the filter screen.

[0015] In this solution, the denitrification liquid inside the nitrification tank is discharged through the drain pipe by a control valve, and the air inlet pipe is used to connect to the external exhaust equipment.

[0016] In one embodiment of this utility model, the front of the denitrification box is hinged to the top via a door and a pull rod is provided in the middle of the top. The interior of the denitrification box has sliding grooves on both sides of the fiber filter and the filter screen. The bottom of the denitrification box has support legs at all four corners.

[0017] In this design, the pull rod facilitates the opening of the chamber door, the sliding groove is used to fix the filter screen, making it easy to clean the filter screen and the inside of the denitrification chamber, and the support legs increase the height of the denitrification chamber.

[0018] In one embodiment of this utility model, a switch panel is provided on one side surface of the denitrification chamber located on the side of the water pump. A micro motor switch, a water pump switch, a heating plate switch, and a temperature sensor switch are respectively provided on one side of the switch panel. The switch panel is electrically connected to an external power supply.

[0019] In this solution, the electrical equipment is powered through a switch panel, and the independent switch provides independent protection for the electrical equipment.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] The denitrification liquid is sprayed through the nozzle via the connecting pipe and support pipe, making the sprayed liquid finer. A micro motor drives the fan blades to rotate, which better mixes the flue gas with the denitrification liquid, improving the denitrification effect. The fiber filter can store the denitrification liquid, requiring the flue gas to pass through it, increasing the contact between the flue gas and the denitrification liquid, and better mixing them. The fiber filter is coated with lysozyme, which can efficiently dissolve captured microorganisms and bacteria, achieving sterilization and preventing secondary pollution. The filter screen is used to remove larger particulate matter from the flue gas. A temperature sensor detects internal temperature changes in real time and provides timely feedback on the system status, ensuring operation within the set optimal temperature range. The heating plate is used to maintain the optimal temperature required for the denitrification reaction, preventing cooling or excessively low temperatures from reducing reaction efficiency, thereby improving denitrification efficiency. The pull rod facilitates opening the door, making it easy to clean the filter screen and the inside of the denitrification chamber. Attached Figure Description
