Embodiment 1
[0037] like figure 1 , figure 2 and image 3 As shown, the pickling equipment of the present invention includes an acid storage tank 1, a pressurized tank 2, a confluence tank 5, a diversion tank 6, an acid water collector 7 and a waste acid tank 10, and the acid storage tank 1 and the pressurized tank 2 connection, the pressurized tank 2 is connected with the gas storage tank 3, the two ends of the confluence tank 5 are closed, and one side thereof is connected with the pressurized tank 2, the gas storage tank 3 and the water storage tank 4, and the other side is set There are a plurality of interfaces 5-1 connected to one end of the pipe material 12, the other end of the pipe material 12 goes deep into the diversion groove 6, the bottom end of the diversion groove 6 is provided with an outlet, and the acid water collector 7 is located in the Below the outlet and its bottom are provided with a first passage 7-2 communicating with the acid storage tank 1 and a second passag...
Embodiment 2
[0047] combine Figure 1 to Figure 3 In this embodiment, the method for pickling rare metal pipes and rare metal alloy pipes using the equipment described in Embodiment 1 includes the following steps:
[0048] Step 1. Preparatory work: install one end of a plurality of pipes 12 to be pickled on the interface 5-1, and the other end goes deep into the diversion tank 6, put the acid solution into the acid storage tank 1, and then open the first valve 9 -1 and the second valve 9-2, the acid solution is injected into the pressurized tank 2, then the first valve 9-1 and the second valve 9-2 are closed, the third valve 9-3 is opened, and the acid solution is injected into the pressurized tank 2 Inflate, close the third valve 9-3 after the pressure in the pressurized tank 2 rises to 0.1MPa;
[0049] In this embodiment, the pipe 12 to be pickled is specifically a titanium pipe, the inner diameter of the pipe is 20mm, the length of the pipe is 2000mm, and the number of pipes 12 to be pic...
Embodiment 3
[0055] combine Figure 1 to Figure 3 In this embodiment, the method for pickling rare metal pipes and rare metal alloy pipes using the equipment described in Embodiment 1 includes the following steps:
[0056] Step 1. Preparatory work: install one end of a plurality of pipes 12 to be pickled on the interface 5-1, and the other end goes deep into the diversion tank 6, put the acid solution into the acid storage tank 1, and then open the first valve 9 -1 and the second valve 9-2, the acid solution is injected into the pressurized tank 2, then the first valve 9-1 and the second valve 9-2 are closed, the third valve 9-3 is opened, and the acid solution is injected into the pressurized tank 2 Inflate, close the third valve 9-3 after the pressure in the pressurized tank 2 rises to 0.1MPa;
[0057] In this embodiment, the pipe material 12 to be pickled is specifically a titanium alloy pipe, the inner diameter of the pipe material is 15mm, the length of the pipe material is 1800mm, a...
