Description

Technical Field

[0002] Ammonia recovery treatment device is a wastewater treatment equipment commonly used in industrial wastewater treatment. It is usually a device used to extract ammonia from wastewater for its recovery.

[0003] When a deammonification tower is used to extract and recycle ammonia in the wastewater during the treatment of industrial wastewater, multiple delivery pipes are usually installed on the water inlet pipe, the water outlet pipe, the air inlet pipe and the air outlet pipe, and then wastewater is injected into the water inlet pipe and adsorbed gas is injected into the air inlet pipe to extract the ammonia in the wastewater and discharge it from the air outlet pipe. The treated wastewater is then transported from the water outlet pipe to the next treatment step for treatment. Generally, a sealing block is placed at the connection between the delivery pipe and the water inlet pipe for extrusion sealing, so that gaps are not likely to occur at the connection, resulting in wastewater leakage. After the sealing block has been used for a long time, the external part in contact with the air is prone to corrosion and aging, thereby reducing the sealing effect. When replacing, the delivery pipe needs to be removed from the water inlet pipe to replace it, which makes the operation steps more cumbersome and reduces the work efficiency of deammonification.

[0033] Working principle: When the deammonification tower 1 is used to extract and recycle ammonia in the wastewater during the treatment of industrial wastewater, multiple delivery pipes are usually installed on the water inlet pipe 4, the water outlet pipe 5, the air inlet pipe 6 and the air outlet pipe 7 respectively. At this time, the sealing block 26 is manually held and wrapped around the connection between the water inlet pipe 4 and the delivery pipe to overlap the interfaces. Then the elastic clamping block 27 is clamped at the interface of the sealing block 26 to preliminarily fix it. At this time, the elastic block 22 is clamped on the outer surface of the elastic clamping block 27 so that the clamping hole rod 21 on the outer surface is clamped into the inner wall of the clamping groove block 31. Then, the pull block 34 is held to clamp the iron rod 33 from the second circular hole 32 so that it is clamped into the inner wall of the clamping hole rod 21 to a certain position, and then it is adsorbed and fixed by the magnet block 35, so that the clamping hole rod 21 can be fixedly installed on the deammonification tower 1.

After screwing to a certain position, one side of the two ends of the elastic block 22 is abutted against one side of the two ends of the elastic block 22 to tighten it, so that the sealing block 26 and the elastic clamping block 27 can be clamped and fixed to make it seal more tightly. Similarly, when replacement is needed, only the opposite operation is required to replace the sealing block 26. The sealing block 26 can be replaced without removing the delivery pipe from the water inlet pipe 4, thereby improving the replacement efficiency and the deammonification work efficiency. The same installation steps are also used on other pipelines. After installation, wastewater is injected into the water inlet pipe 4, and adsorbed gas is injected into the air inlet pipe 6, so that it extracts the ammonia element in the wastewater and discharges it from the air outlet pipe 7, and then the treated wastewater is transported from the water outlet pipe 5 to the next treatment step for treatment.
