Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic-assisted ammonia nitrogen stripping devices, in particular to an ultrasonic-assisted ammonia nitrogen stripping device. Background Art

[0002] Wastewater refers to water produced in the process of human life and production that has lost its original use value and is discharged. Wastewater containing ammonia nitrogen is a common industrial wastewater, mainly coming from the chemical industry, which produces a large amount of high-concentration ammonia nitrogen wastewater. When a large amount of ammonia nitrogen wastewater is discharged into the water body, it will not only cause eutrophication and black and smelly water, but also increase the difficulty and cost of water treatment, and even have a toxic effect on people and organisms. The impact of ammonia nitrogen wastewater on the environment has attracted attention in the environmental protection field and globally.

[0003] When treating the ammonia nitrogen content in wastewater, an ultrasonic-assisted ammonia nitrogen stripping device is usually used. The efficiency of ammonia nitrogen stripping can be improved through the auxiliary effect of ultrasound. The working principle of the ultrasonic-assisted ammonia nitrogen stripping device is mainly based on the physical effect of ultrasound and the gas-liquid equilibrium relationship of ammonia nitrogen. The ultrasonic vibration effect accelerates the separation and transfer process of ammonia nitrogen, making the wastewater treatment speed faster.

[0004] Currently, when using the ultrasonic-assisted ammonia nitrogen stripping device, it is usually necessary to first check the integrity of the device, and then spray the wastewater and the prepared solution into the device through the atomizing nozzle, so that the atomized wastewater comes into contact with the material in the filler device, so as to increase the contact area between the wastewater and the air, and then start the device to adjust the parameters, so that the ammonia nitrogen in the wastewater can be stripped through the ultrasonic generator.

[0005] However, when installing the packing device, it is necessary to install flanges on the packing device and the inner wall of the stripping tower respectively, and then tightly connect the two flanges together with bolts. Since the packing device needs to be replaced after long-term use, and this connection method is relatively complicated, it is easy to reduce work efficiency. Utility Model Content

[0006] Based on this, the purpose of the utility model is to provide an ultrasonically assisted ammonia nitrogen stripping device to solve the technical problems that the packing device needs to be replaced after long-term use, and the connection method between the packing device and the inner wall of the stripping tower is relatively complicated, which easily reduces work efficiency.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultrasonically assisted ammonia nitrogen stripping device, comprising a base, the top of the base is fixedly connected to a stripping tower body, a group of ultrasonic emitters are installed on the surface of the stripping tower body, a group of slots are provided on the inner wall of the stripping tower body, each of the slots is movably connected to a frame body, three layers of filler material are provided in the frame body, and the three layers of filler material are respectively arranged as an annular structure, a plate-type structure and a corrugated structure, a plurality of threaded rods are rotatably connected inside the frame body, and a group of fixed blocks that fit with the slots are fixedly connected to the surface of each threaded rod, and the fixed blocks are respectively located at the top and bottom of the frame body, and an air bag that fits with the slots is provided on the surface of the frame body.

[0008] By adopting the above technical solution, when the frame is installed, it can be made to reach the corresponding slot position, and then the threaded rod and the fixed block are rotated in sequence so that the threaded rod and the fixed block enter the slot, thereby fixing the frame. Then, gas is filled into the airbag to expand the airbag, which can not only increase the connectivity between the frame and the stripping tower body, but also support the adjacent fixed blocks, making it easier to fix the frame again, avoiding the increase in the weight of the filling material and the frame due to long-term use, thereby causing the fixed plate to deform, affecting the fixation of the frame.

[0010] By adopting the above technical solution, wastewater can enter the interior of the stripping tower through the first connecting pipe, and then pass through the nozzle to facilitate small water droplets to enter the interior of the stripping tower, so that the wastewater can fully contact with the filling material, which is convenient for increasing its contact area with the air, so that the ultrasonic emitter can better strip the ammonia nitrogen in the wastewater. At the same time, gas is transported to the stripping tower through the second connecting pipe and then sprayed out through the air port, which is convenient for stripping harmful substances such as ammonia nitrogen in the wastewater.

At the same time, the design of the ladder and platform allows the staff to reach the visual windows at different heights for observation, which also facilitates the maintenance and inspection of the stripping tower by the staff.

[0013] The utility model is further configured such that an air inlet is provided at the bottom of the airbag, and a top cover is threadedly connected to the surface of the air inlet.

[0014] By adopting the above technical solution, the design of the air inlet and the top cover makes it easy to inflate the airbag, thereby expanding it, and facilitating the connection between the frame and the stripping tower body, thereby increasing the stability of the frame.

[0015] The present invention is further configured such that the top and the bottom of the frame are both provided with a plurality of receiving slots that fit with the fixing blocks.

[0016] By adopting the above technical solution, the fixing block can be stored in the storage slot, which can protect the fixing block when the frame is not installed, thereby preventing it from being damaged during transportation and affecting its use.

[0017] The present invention is further configured such that a plurality of protrusions are fixedly connected to the surface of the airbag.

[0018] By adopting the above technical solution, when the airbag is expanded, the friction between the airbag and the stripping tower body can be increased by the protrusions, thereby increasing the stability and durability of the frame.

[0020] By adopting the above technical solution, the setting of the exhaust port can allow the gas in the stripping tower to be discharged through the exhaust port. At the same time, the design of the liquid discharge port facilitates the discharge of the treated liquid, thereby ensuring the continuous operation of the device and improving work efficiency.

[0021] In summary, the present invention has the following beneficial effects:

[0022] 1. The utility model rotates the threaded rod and the fixing block in sequence so that the threaded rod and the fixing block enter the slot, thereby fixing the frame, and then filling the air bag with gas to expand the air bag, which can not only increase the connectivity between the frame and the stripping tower body, but also support the adjacent fixing blocks, making it easier to fix the frame again and avoid increasing the weight of the filling material and the frame due to long-term use, thereby causing the fixing plate to deform and affecting the fixation of the frame. This structure can quickly realize the installation and disassembly of the frame, facilitates the replacement of the filling material, and can improve work efficiency.
