In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, an acid adding apparatus includes: an acid adding pipeline 7 and a driving mechanism 10. The inlet of the acid adding pipe 7 is connected to an acid source (not shown in the figure), and the outlet of the acid adding pipe 7 is inserted into the neutralization tank 6 to supply the acidic substance to the neutralization tank 6. The driving mechanism 10 is connected with the acid adding pipeline 7, and the driving mechanism 10 can drive the acid adding pipeline 7 to lift so as to adjust the position of the acid adding pipeline 7 inserted into the neutralization tank 6.
Specifically, as shown in fig. 1, the neutralization tank 6 may be connected to a secondary circuit of a power plant or some other circuit for discharging alkaline wastewater, and in order to meet environmental discharge standards, it is necessary to neutralize the alkaline wastewater in the neutralization tank 6. Before neutralization, an outlet of an acid adding pipeline 7 is inserted into the neutralization tank 6 and is positioned below the liquid level of the neutralization tank 6, and the acid adding pipeline 7 introduces acidic substances in an acid source into the neutralization tank 6 so as to realize neutralization reaction with alkaline wastewater in the neutralization tank 6. Because the outlet of the acid adding pipeline 7 is lower than the liquid level of the neutralization tank 6, the acid adding process can not contact with the air, thereby avoiding the generation of acid mist in the air, protecting the power plant equipment from being corroded and protecting the personal safety of workers. In addition, as the outlet of the acid adding pipeline 7 is higher than the liquid level of the neutralization tank 6 due to wastewater discharge or other reasons, the driving mechanism 10 drives the acid adding pipeline 7 to descend, so that the outlet of the acid adding pipeline 7 is positioned below the liquid level of the neutralization tank 6 again. On the contrary, if the outlet of the acid adding pipeline 7 is far lower than the liquid level of the neutralization tank 6, the driving mechanism 10 drives the acid adding pipeline 7 to ascend, so that the outlet of the acid adding pipeline 7 is lower than the preset value (such as 30 cm-50 cm) of the liquid level of the neutralization tank 6.
According to the acid adding device, the outlet of the acid adding pipeline is inserted into the neutralization tank, the acid adding pipeline is driven to lift by the driving mechanism, so that the outlet of the acid adding pipeline is ensured to be positioned below the liquid level of the neutralization tank, the acid adding process cannot contact air, and the generation of acid mist in the air is avoided. When the device is used in the wastewater treatment process of a power plant, the device of the power plant can be effectively protected from being corroded, and the personal safety of workers can be protected. It should be noted that the driving mechanism 10 may adopt a rack and pinion mechanism, a slider-crank mechanism, a linear motor, or the like.
