Description

Technical Field

[0001] This utility model belongs to the field of waste liquid treatment technology, specifically relating to a neutralization treatment device for HF-containing waste liquid. Background Technology

[0002] In existing technologies, HF-containing waste liquid is highly corrosive. Direct discharge would severely pollute the environment and pose significant hazards to equipment and human health, thus requiring neutralization treatment. However, traditional neutralization devices have several shortcomings: existing devices discharge waste liquid and neutralizing liquid into a tank and use a stirring structure to agitate the waste liquid. However, the mixing of waste liquid and neutralizing liquid in existing devices is insufficient and uneven, resulting in low neutralization efficiency and incomplete neutralization in some areas, affecting the treatment effect. In addition, traditional devices do not have a premixing structure before the waste liquid and neutralizing liquid enter the treatment tank, resulting in poor initial mixing within the tank and requiring longer agitation time to achieve the ideal neutralization state, which is time-consuming and labor-intensive. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a neutralization and treatment device for HF-containing waste liquid, so as to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this HF-containing waste liquid neutralization and treatment device to solve its technical problem is as follows: A neutralization and treatment device for HF-containing waste liquid is provided, including a tank. A first motor is fixedly installed on the top of the tank. The output end of the first motor passes through the tank and is fixedly installed on a first rotating shaft. A stirring blade is fixedly installed on the first rotating shaft. An extension box is fixedly installed in a mounting groove on one side of the bottom of the tank. The extension box is connected to the inside of the tank. A vertical pipe is fixedly installed on the extension box and is connected to the inside of the extension box. A second motor is fixedly installed on the top of the vertical pipe. The output end of the second motor passes through the vertical pipe and is fixedly installed on a second rotating shaft. A first spiral blade is fixedly installed on the outer periphery of the second rotating shaft. A drain pipe is fixedly connected to the top of the vertical pipe. A return pipe is fixedly connected to the vertical pipe. The return pipe passes through the tank and is fixedly connected. The return pipe is eccentrically connected to the tank. A neutralization premixing pipe is eccentrically connected to the tank. A slag discharge port is provided at the bottom of the tank.

[0005] Furthermore, a second helical blade is fixedly installed on the first rotating shaft.

[0006] Furthermore, the neutralization premixing pipe includes a waste liquid pipe eccentrically connected to the tank body, and a neutralization liquid pipe is fixedly connected to the waste liquid pipe.

[0007] Furthermore, the neutralizing liquid pipe is completely inserted into the waste liquid pipe and completely blocks the waste liquid pipe. Several connecting pipes are evenly fixed on the neutralizing liquid pipe. The connecting pipes can connect the two sides of the neutralizing liquid pipe and connect the waste liquid pipe. Several drainage holes are opened on the neutralizing liquid pipe and are staggered between the connecting pipes.

[0008] Furthermore, a one-way valve is provided inside the reflux pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides an example of a neutralization treatment device for HF-containing waste liquid. In use, the waste liquid and neutralizing liquid are premixed through a neutralization premixing pipe. Starting the first motor drives the first rotating shaft and stirring blades to rotate. The stirring blades deflect the flow of the waste liquid in the tank in the opposite direction to the inlet direction of the neutralization premixing pipe, creating turbulent flow between the two streams. This turbulence improves the mixing effect. Simultaneously, the second motor starts, lifting the waste liquid through the first spiral blades. Part of the waste liquid is discharged from the drain pipe, while the other part flows back into the tank through the return pipe. The stirring blades deflect the flow of the waste liquid in the tank in the opposite direction to the return flow direction, again creating turbulent flow and improving neutralization efficiency and effect. This device facilitates the treatment of HF-containing waste liquid, improves neutralization efficiency, and is more convenient to use.

[0012] 2. The HF-containing waste liquid neutralization treatment device of this utility model can lift the liquid in the tank through the second spiral blade, thereby improving the mixing effect.

[0014] 4. In the present invention, a waste liquid containing HF neutralization treatment device is provided. During use, the waste liquid and the neutralizing liquid are discharged into the waste liquid pipe from the connecting pipe and the drain hole, respectively. Premixing can be performed before stirring, which can improve the neutralization efficiency and effect.

[0015] 5. The HF-containing waste liquid neutralization treatment device of this utility model can prevent unneutralized waste liquid from flowing into the vertical pipe from the return pipe through the one-way valve in the return pipe.

[0016] 6. An example of this utility model is a neutralization treatment device for HF-containing waste liquid. Through an exhaust gas pipe, the waste gas generated during the neutralization process can be guided and treated through a multi-stage gas scrubbing tank.
