Description

Technical Field

[0001] This utility model relates to the field of ammonia water collector technology, and in particular to an ammonia water collector for low-temperature denitrification catalyst production. Background Technology

[0002] The core function of low-temperature denitrification catalysts is to efficiently catalyze the reduction of nitrogen oxides in flue gas at lower temperatures, converting them into harmless nitrogen and water, thereby achieving denitrification and purification of industrial flue gas and reducing air pollution. However, low-temperature denitrification catalysts produce ammonia water during production, which needs to be collected and treated using an ammonia water collector.

[0003] An investigation revealed that patent CN214987663U discloses an ammonia water collector for low-temperature denitrification catalyst production, relating to the field of low-temperature denitrification catalyst production technology. The collector includes a base plate with casters fixedly installed at each of the four corners of its bottom surface. Support plates are fixedly installed along the middle of the left and right sides of the upper surface of the base plate. A groove is formed in the middle of the support plate, and a lifting block is movably disposed within the groove. A screw is inserted into the center of the lifting block, and the screw is threadedly connected to the lifting block. The advantages are: the casters facilitate movement; the shaft is connected to the lifting block via bearings, ensuring the receiving container remains vertical under gravity, adapting to use on inclined surfaces; a drive motor raises and lowers the lifting block, supported by rollers, allowing the receiving container to tilt and lower its height for easier movement; and a hydraulic cylinder supports the lifting and lowering of the hopper to accommodate material at different heights, meeting various usage requirements.

[0004] This patent uses a receiving tank to collect and pour ammonia water. However, the receiving tank is quite heavy after collecting ammonia water, and directly pouring the ammonia water would cause the supporting structure to bear a large load, which could easily damage the collector in the long run. In addition, some ammonia gas will evaporate during the collection and pouring of ammonia water, which will have an adverse effect on the health of the operators if inhaled. Therefore, there is a need for a low-temperature ammonia water collector for the production of denitrification catalysts to meet the usage requirements. Utility Model Content

[0013] Preferably, a push handle is installed at the front end of the receiving bucket, and casters are installed at the bottom of the base plate.

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

[0015] In this invention, some of the ammonia gas that evaporates during the overcharging process with ammonia water is drawn into the first suction pipe through the first suction ring, then enters the gas delivery pipe through the first suction pipe, and finally enters the dissolving water tank through the gas delivery pipe. Since ammonia gas is almost infinitely soluble in water, the evaporated ammonia gas entering the dissolving water tank will be absorbed by the water, preventing operators from inhaling it.

[0016] In this invention, by manually pulling the second sealing cap and removing the second sealing plug from the discharge pipe, the ammonia water collected in the receiving tank will be discharged through the discharge pipe, eliminating the need for direct pouring through the receiving tank and preventing structural damage to the collector. The ammonia gas volatilized during the pouring process will be drawn into the second suction pipe through the second suction ring, and then re-enter the dissolving water tank through the gas delivery pipe to be dissolved in water.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0023] like Figure 1-4As shown, this embodiment provides an ammonia water collector for low-temperature denitrification catalyst production, including a receiving tank 1 and a base plate 2. An adding pipe 3 is installed at the top of the receiving tank 1, with a first sealing plug 4 plugged inside the adding pipe 3. A first cap 5 is installed on the first sealing plug 4. A discharging pipe 6 is installed on the receiving tank 1, with a second sealing plug 7 plugged inside the discharging pipe 6. A second cap 8 is installed on the second sealing plug 7. A first suction ring 9 and a second suction ring 10 are respectively installed on the outer sides of the adding pipe 3 and the discharging pipe 6. A dissolving water tank 11 is installed on the base plate 2. Moving the first cap 5 and the first sealing plug 4 upwards will cause the first sealing plug 4 to be pulled out of the adding pipe 3. Rotating the first cap 5 and the first sealing plug 4 will cause them to be misaligned with the adding pipe 3. Ammonia water produced during the catalyst production process is then poured into the receiving tank 1 through the adding pipe 3. Part of the ammonia gas that evaporates during the ammonia water overcharging process is sucked into the dissolving water tank 11 through the first suction ring 9. Since ammonia is almost infinitely soluble in water, the volatilized ammonia gas entering the dissolving water tank 11 will be absorbed by the water, thus preventing operators from inhaling it.

[0024] Similarly, when it is necessary to discharge the ammonia water collected in the receiving tank 1, manually pull the second sealing cap 8 and pull the second sealing plug 7 out of the discharge pipe 6. At this time, the ammonia water collected in the receiving tank 1 will be discharged through the discharge pipe 6, without needing to be poured directly through the receiving tank 1, thus avoiding structural damage to the collector. The ammonia gas volatilized during the pouring process will be sucked into the dissolving water tank 11 through the second suction ring 10 and dissolved in water.

[0025] To facilitate the removal of the No. 1 sealing plug 4 from the adding tube 3 and to misalign the No. 1 sealing plug 4 with the adding tube 3, a connecting plate 12 is provided above the No. 1 cap 5. A drive motor 13 is mounted on the connecting plate 12, and a rotating shaft 14 is mounted on the output end of the drive motor 13. The bottom end of the rotating shaft 14 is mounted on the No. 1 cap 5. An electric lifting rod 15 is mounted on the top of the receiving tank 1, and the output end of the electric lifting rod 15 is mounted on the connecting plate 12. When the electric lifting rod 15 extends, it will cause the connecting plate 12, the drive motor 13, and the rotating shaft 14 to move upward. The upward movement of the rotating shaft 14 will cause the No. 1 cap 5 and the No. 1 sealing plug 4 to move upward, thereby causing the No. 1 sealing plug 4 to be removed from the adding tube 3. When the drive motor 13 is restarted, the rotation of the drive motor 13 will cause the rotating shaft 14 to rotate, which will cause the No. 1 cap 5 and the No. 1 sealing plug 4 to rotate and misalign with the adding tube 3.

[0026] To ensure that the volatilized ammonia gas is transported to the dissolving water tank 11 for dissolution during the addition or discharge of ammonia water, an exhaust fan 16 is installed above the base plate 2. The exhaust fan 16 has a first exhaust pipe 18 installed at its suction end, a first suction ring 9 installed on the first exhaust pipe 18, a connector 19 installed on the first exhaust pipe 18, a second exhaust pipe 20 installed on the connector 19, a second suction ring 10 installed on the second exhaust pipe 20, and a gas delivery pipe 17 installed at the exhaust end of the exhaust fan 16. The bottom end of the gas delivery pipe 17 is installed inside the dissolving water tank 11. This system is used to dissolve ammonia gas that volatilizes during the addition or overcharging of ammonia water. The gas will be drawn into the first suction pipe 18 through the first suction ring 9, and then into the gas supply pipe 17 through the first suction pipe 18. Finally, it will enter the dissolving water tank 11 through the gas supply pipe 17. The volatilized ammonia gas will be absorbed by the water in the dissolving water tank 11 to prevent the operator from inhaling it. The ammonia gas volatilized during the pouring and overfilling process will be drawn into the second suction pipe 20 through the second suction ring 10, and then enter the dissolving water tank 11 through the gas supply pipe 17 to be dissolved by the water.

[0027] To transport the ammonia solution in the dissolving tank 11 to the receiving tank 1 for collection, the dissolving tank 11 is equipped with a valve 21 and a pump 22. The inlet and outlet of the pump 22 are respectively connected to a pumping pipe 23 and a delivery pipe 24. The delivery pipe 24 is installed inside the receiving tank 1 and is equipped with a check valve 25. When the pump 22 is started and the check valve 25 is opened, the pump 22 will transport the ammonia solution in the dissolving tank 11 to the receiving tank 1 through the pumping pipe 23 and the delivery pipe 24. During the operation of the base plate 2, the valve 21 can adapt to pressure changes and open under pressure to draw in external air into the dissolving tank 11. When not pumping ammonia solution, the valve 21 can prevent ammonia gas from evaporating and overflowing.

[0028] Working principle: During use, the operator holds the push handle 26 and pushes the device. The casters 27 roll and turn on the ground, moving the device to the appropriate position. Then, the electric lifting rod 15 is activated. The extension of the electric lifting rod 15 will move the connecting plate 12, drive motor 13, and rotating shaft 14 upward. The upward movement of the rotating shaft 14 will move the first cap 5 and the first sealing plug 4 upward, causing the first sealing plug 4 to be pulled out from the addition pipe 3. Then, the drive motor 13 is activated. The rotation of the drive motor 13 will drive the rotating shaft 14 to rotate, causing the first cap 5 and the first sealing plug 4 to rotate and become misaligned with the addition pipe 3. The exhaust fan 16 is activated beforehand, and then the ammonia water produced in the catalyst production process is poured into the receiving tank 1 through the addition pipe 3. During the ammonia overcharge process, some of the ammonia gas that evaporates is drawn into the first suction pipe 18 through the first suction ring 9, then into the gas delivery pipe 17, and finally into the dissolving water tank 11. Since ammonia is almost infinitely soluble in water, the evaporated ammonia gas is absorbed by the water in the dissolving water tank 11, preventing operators from inhaling it. Similarly, when it is necessary to discharge the ammonia water collected in the receiving tank 1, the second sealing cap 8 is manually pulled, and the second sealing plug 7 is pulled out from the discharge pipe 6. At this time, the ammonia water collected in the receiving tank 1 will be discharged through the discharge pipe 6, without needing to be poured directly through the receiving tank 1, thus avoiding structural damage to the collector. During the pouring overcharge process, the ammonia gas that evaporates is drawn into the second suction pipe 20 through the second suction ring 10, and then again enters the dissolving water tank 11 through the gas delivery pipe 17 to be dissolved by water. After long-term use, start the liquid pump 22 and open the one-way valve 25. At this time, the liquid pump 22 will transport the ammonia water in the dissolving water tank 11 to the receiving tank 1 through the liquid delivery pipe 24 via the liquid pumping pipe 23. During the operation of the bottom plate 2, the valve 21 can adapt to pressure changes and open under pressure to draw in external air into the dissolving water tank 11. When not pumping ammonia water, the valve 21 can prevent ammonia gas from evaporating and overflowing.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
