Description

Technical Field

[0001] This utility model relates to the field of ammonia water transportation, and in particular to an ammonia water transportation system for a denitrification device. Background Technology

[0002] A denitrification unit is a device used to remove nitrogen oxides (NOx) from flue gas. Its working principle is mainly based on a chemical reaction, where NOx in the flue gas reacts with a reducing agent (such as ammonia or urea) to produce harmless nitrogen and water vapor. Environmentally friendly denitrification equipment is mainly suitable for flue gas denitrification treatment in industries such as coal-fired power generation, steel, cement, petrochemicals, and glass.

[0003] The ammonia water delivery system in a denitrification unit is a critical component, especially in denitrification technologies such as selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR). Ammonia water is transported into the flue gas as a reducing agent to react with nitrogen oxides (NOx) and remove NOx from the flue gas. During the delivery process, if too much sediment accumulates in the ammonia water pipeline, it can lead to pipe blockage, affecting the normal delivery of ammonia water, the service life of the equipment, and the stable operation of the denitrification system.

[0004] Therefore, to address the issue that excessive sediment in existing ammonia pipelines can lead to blockages, affecting the normal transport of ammonia, the lifespan of equipment, and the stable operation of the denitrification system, an ammonia transport system for the denitrification device can be designed. This system utilizes anti-clogging components to treat the transported ammonia, thereby improving the overall transport efficiency. Utility Model Content

[0005] In order to overcome the problem that excessive sediment in existing ammonia water pipelines can lead to pipe blockage, affecting the normal delivery of ammonia water, the service life of equipment, and the stable operation of the denitrification system.

[0006] The technical solution of this utility model is as follows: an ammonia water conveying system for a denitrification device, comprising a transmission pipe, a node impurity treatment box, a filter assembly, a transmission guiding assembly, a filling pipe, and a filter plate; three sets of node impurity treatment boxes for filtering impurities and conveying ammonia water are linearly connected in sequence on the transmission pipe; filling pipes for adding impurity solvents are provided on both sides of the node impurity treatment box; a filter plate for refining filtration is provided between the transmission pipe and the node impurity treatment box; a filter assembly for circulating filtration of ammonia water impurities is provided at the top of the node impurity treatment box; and a transmission guiding assembly for guiding water flow filtration is provided at the bottom of the node impurity treatment box and is sleeved with the filter assembly inside.

[0007] Preferably, a filter plate is installed between the transmission pipe and the node impurity treatment box to refine the filtration. A filter assembly is installed at the top of the node impurity treatment box to deeply circulate and filter ammonia impurities. A transmission guide assembly is installed at the bottom of the node impurity treatment box to deeply connect with the filter assembly inside to guide water flow filtration, thereby improving the overall conveying effect.

[0008] Preferably, the top and bottom of the node impurity treatment box are provided with first mounting sleeves for installing filter components and transmission guide components. The first mounting sleeves are provided with positioning holes for positioning near the edge. The node impurity treatment box is provided with mounting brackets symmetrically on both sides of the filling pipe. The mounting brackets are provided with mounting holes linearly. The inner side of the first mounting sleeve is provided with a sealing ring, which can be used to perform overall sealing treatment.

[0009] Preferably, the side wall of the node impurity treatment box is provided with injection holes that communicate with the filling pipe. The injection holes are equipped with injectors, and the rear end of the injectors is equipped with electromagnetic control valves. The electromagnetic control valves are surrounded by control power supply groups. One end of the control power supply group is equipped with a vibrator that extends into the node impurity treatment box. A disassembly plate is provided between the node impurity treatment box and the mounting sleeve. Disassembly bolts are provided at all four corners of the disassembly plate. By using the disassembly bolts to process the disassembly plate, internal maintenance operations can be performed.

[0010] Preferably, the filter assembly includes a filter element, a closed plate, a first drive motor, a connecting frame, a first limiting hole, a second mounting sleeve, and a filter tank. The outer end of the closed plate is provided with a connecting frame, one end of which is provided with a first limiting hole. The center of the closed plate is provided with a filter element, through which overall filtration can be performed.

[0011] Preferably, the filter element has a filter groove circumferentially opened at the outer end, a transmission shaft at the top of the filter element, a first drive motor at the top of the transmission shaft, the first drive motor drives the transmission shaft to rotate the filter element, and a second mounting sleeve is provided at the bottom center of the filter element. The first drive motor drives the transmission shaft to rotate the filter element, thereby increasing the overall rotation effect.

[0012] Preferably, the filter plate is provided with evenly distributed diversion holes, and the transmission guide assembly includes a stabilizing plate, an adapter ring, a second limiting hole, a second drive motor and an adapter column. The stabilizing plate is provided with an adapter ring on its periphery, and a rotating ring is provided between the adapter ring and the stabilizing plate. The stabilizing plate is provided with an adapter column at the center of its end. The stabilizing plate increases the rotational counterweight performance.

[0013] Preferably, a flow-guiding arc plate is provided circumferentially near the edge of the end of the stabilizing plate. The second drive motor drives the stabilizing plate to rotate along the inside of the adapter ring. A second limiting hole is provided circumferentially on the adapter ring, through which the adapter can be installed.

[0014] The beneficial effects of this utility model are:

[0015] 1. Unlike previous methods where excessive sediment in ammonia pipelines could cause blockages, affecting normal ammonia delivery, equipment lifespan, and stable denitrification system operation, this new system utilizes three linearly connected impurity treatment boxes on the transmission pipe. These boxes filter impurities during ammonia delivery. A filling pipe, located on either side of the box, adds impurity solvents. A filter plate, positioned between the transmission pipe and the box, refines the filtration. A filter assembly, located at the top of the box, deeply circulates and filters ammonia impurities. Finally, a transmission guide assembly, located at the bottom, connects to the filter assembly to guide water flow, improving overall delivery efficiency.

[0016] 2. During the conveying process, ammonia water is transported through the transmission pipe. The filter element is connected to the adapter column through the second mounting sleeve. The first drive motor drives the transmission shaft to rotate the filter element counterclockwise. The second drive motor drives the stabilizing disc to rotate the flow-guiding arc plate along the inside of the adapter ring clockwise, forming an interactive guide to filter impurities in the ammonia water. The impurities are guided to decompose the solution through the injection pipe and sprayed through the injection hole by the injector to dissolve the internal water. Subsequently, the control power group drives the vibrating rod to vibrate the impurities in the solution, improving the decomposition effect and performing sequential fine processing.
