Description

Technical Field

[0001] The utility model relates to the technical field of ammonia water evaporators, in particular to a hot air type ammonia water evaporator. Background Art

[0002] Ammonia evaporators are divided into steam-type ammonia evaporators and hot air-type ammonia evaporators according to different heat sources. The hot air-type ammonia evaporator mainly includes ammonia metering and distribution, ammonia injection atomization, evaporator body, hot air pressurization system, etc. First, ammonia is pumped from the tank area to the ammonia metering and distribution module through an ammonia delivery pump, and then enters the ammonia injection system after metering and deployment. It is atomized and injected into the ammonia evaporator body by compressed air, mixed and evaporated with the pressurized hot air in the evaporator, and becomes a mixed gas of ammonia / air / water vapor and sent to the SCR reactor. In order to ensure the atomization effect , it is necessary to regularly remove the ammonia injector from the evaporator body and perform maintenance and repair on it. For the hot air ammonia evaporator, its interior is in a high temperature and slightly positive pressure state during operation. In order to avoid the instantaneous high-temperature airflow ejected when the ammonia injector is removed and cause harm to the staff, it is necessary to stop the operation of the evaporator body and wait for the internal temperature to cool down before removing the ammonia injector. If it is disassembled without shutting down the instrument, the high-temperature gas inside will eject, which can easily cause burns to the staff and pose a certain risk. For this reason, we have proposed a hot air ammonia evaporator. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 5 A hot air ammonia evaporator comprises an ammonia evaporator body 1, a mixed gas delivery pipeline 2 is installed on the top of the ammonia evaporator body 1, a hot air delivery pipeline 3 is installed at the bottom of the ammonia evaporator body 1, a sewage pipe 4 and a connecting pipe 5 are respectively installed on the ammonia evaporator body 1, and the connecting pipe 5 is connected to an ammonia injection pipeline 6, the connecting pipe 5 is connected to the inside of the ammonia injection pipeline 6, and a locking plate 7 is fixedly connected to one end of the connecting pipe 5 and the ammonia injection pipeline 6, and a movable driving ring plate 8 is installed on one side of the locking plate 7, so that the locking plate 7 and the driving ring plate 8 can rotate relative to each other, so that when installing, the driving ring plates 8 are plugged in, so that the driving ring plates 8 can be linked, so that they can be moved together The driving ring plates 8 are rotated and plugged into each other. A connecting column 11 is fixed on one side of the locking plate 7, and a sealing plate 13 with a sealing function is movably connected to the connecting column 11, so that the sealing plate 13 can rotate with the connecting column 11 as the rotating axis. When all the sealing plates 13 are combined, a sealing effect can be achieved. A reset spring 16 is connected between the locking plate 7 and the driving ring plate 8. The sealing plate 13 is driven by the relative rotation between the locking plate 7 and the driving ring plate 8. The sealing plate 13 can be rotated by the relative rotation between the locking plate 7 and the driving ring plate 8, so that it can be opened and closed. Under the action of the elastic force of the spring 16, the connecting pipe 5 and the ammonia injection pipe 6 can be closed in time after the disassembly is completed.

[0021] See also Figures 1 to 4The locking plates 7 are connected and limited by multiple bolts. Through the limitation of the bolts, the sealing plate 13 can be in an open state, so that the connecting pipe 5 and the ammonia injection pipeline 6 are fixedly installed. A plug-in column 9 is fixed on one side of the driving ring plate 8, and a plug-in groove corresponding to the plug-in column 9 on another driving ring plate 8 is opened on one side of the driving ring plate 8. The plug-in column 9 can be plugged into the plug-in groove on the other driving ring plate 8, so that they can be linked to each other. At the same time, a circular connecting ring plate 10 is sleeved on the inner side of the driving ring plate 8.

[0022] See also Figures 1 to 5 One side of the connecting ring plate 10 is fixed to the connecting column 11. Through the connection of the connecting column 11, the connecting ring plate 10 and the locking plate 7 can be connected, and the two connecting ring plates 10 are abutted against each other, making the connection tighter. At the same time, the connecting column 11 is jointly fixedly connected with a fixing ring 12, and the fixing ring 12 is fixed to one side of the connecting ring plate 10. The sealing plate 13 is connected to a transmission frame 14 that drives it through an axle pin, forming a hinge structure with the axle pin as the rotating axis, so that the sealing plate 13 and the transmission frame 14 can rotate relative to each other, and then the transmission frame 14 can smoothly drive the sealing plate 13 to rotate.

[0023] See also Figures 1 to 5 One end of the transmission frame 14 is connected to the inner side of the driving ring plate 8 through an axle pin, forming a hinge structure with the axle pin as the rotating axis, so that the transmission frame 14 and the driving ring plate 8 can rotate relative to each other, and then the driving ring plate 8 can smoothly drive the transmission frame 14 to rotate, and an arc groove is opened through the driving ring plate 8, and a track fixing column 15 is movably connected in the arc groove. Under the limitation of the track fixing column 15, the driving ring plate 8 can rotate along a fixed track.

[0024] See also Figures 1 to 5 One end of the track-fixing column 15 is fixed to the locking plate 7, so as to determine the relative rotation trajectory between the driving ring plate 8 and the locking plate 7, and one side of the track-fixing column 15 is fixed to the spring 16, and one end of the spring 16 is fixed to the inner wall of the arc groove. Under the action of the elastic force of the spring 16, the driving ring plate 8 can be pushed to reset and rotate.

[0025] See also Figures 1 to 5 When the blocking plate 13 is in the open state, the connecting pipe 5 is connected to the ammonia injection pipe 6, and the spring 16 is in a compressed state at this time, so that after the disassembly is completed, the blocking plate 13 can be automatically closed. The blocking plate 13 and its linked parts together form a closed structure, and the closing structures on the connecting pipe 5 and the ammonia injection pipe 6 are designed in opposite ways, so that they can be closed and opened at the same time.

[0026] In summary, when the hot air ammonia evaporator is used, when installing the connecting pipe 5 and the ammonia injection pipe 6, the plug-in columns 9 on the two driving ring plates 8 are aligned with the plug-in grooves on the other driving ring plate 8 for plugging. When the plugging is completed, the connecting ring plates 10 just abut against each other, and then the ammonia injection pipe 6 is rotated so that the locking plate 7 thereon can rotate, and then the locking plate 7 on the ammonia injection pipe 6 can drive the two driving ring plates 8 to rotate. At this time, the track fixing columns 15 on the two locking plates 7 gradually approach the spring 16, and the spring 16 is gradually compressed. And driven by the driving ring plate 8, the transmission frame 14 can rotate, and then push the sealing plate 13 to rotate, so that the sealing plate 13 can be opened, and then the connecting pipe 5 and the ammonia injection pipe 6 are connected. When the sealing plate 13 is rotated to be fully opened, the two locking plates 7 just correspond to each other, and finally fixed by bolts to complete the installation. When disassembling, the above operation is performed in reverse, so that when the connecting pipe 5 and the ammonia injection pipe 6 are disassembled, under the action of the elastic force of the spring 16, the connecting pipe 5 and the ammonia injection pipe 6 can be in a closed state.
