The circulating pipe I6 is also provided with a cooling mechanism 9, the cooling mechanism 9 can use a conventional device for cooling liquid in the pipeline, and the heat exchanger is adopted in the embodiment, so that the cooling efficiency is higher. Be provided with the cooling medium pipe in the heat exchanger, let in cooling medium to the C end of cooling medium pipe, the B end outflow from the cooling medium pipe has absorbed thermal cooling medium to take away the heat of waste liquid in circulating pipe I6 through cooling medium, reach the effect to waste liquid cooling in circulating pipe I6.
The chlorine pipe 7 is communicated with the circulating pipe I6, so that chlorine is mixed with the waste liquid in the circulating pipe I6, and the chlorine and the waste liquid can be well mixed.
The connection point of the chlorine pipe 7 and the circulation pipe I6, namely, the position A in figure 3, is more than 20cm away from the second end 602. Thus, after the waste liquid in the circulating pipe I6 is preliminarily mixed with the chlorine introduced by the chlorine pipe 7, the chlorine and the waste liquid are further mixed through flowing mixing in the path of more than 20cm, and the chlorine and the waste liquid are fully reacted in the mixing process.
In this embodiment, the position a is located above the second end 602, and the chlorine gas will form bubbles in the waste liquid, and the bubbles will tend to float upward, so that the position a is located above the second end 602, which is beneficial to prolonging the contact reaction time of the chlorine gas and the waste liquid, so that the chlorine gas and the waste liquid are further mixed and reacted.
As shown in FIG. 4, two main tanks 5 are provided, and chlorine pipes 7 are respectively introduced into the two main tanks 5 to treat waste liquid.
As shown in fig. 4, the present embodiment is further provided with a sub-tank 18.
As the reaction proceeds, the waste liquid in the main tank 5 gradually decreases in its ability to absorb chlorine gas, and a part of the chlorine gas is not effectively absorbed. In order to make full use of this portion of unabsorbed chlorine gas, a secondary tank 18 is provided.
The secondary tank 18 is also connected to a feed pipe 26 for receiving waste liquid containing ferrous chloride. And a circulating pipe II 19 is arranged on the auxiliary tank body 18, and two ends of the circulating pipe II 19 are respectively connected to the bottom and the top of the auxiliary tank body 18. And a pump II 20 is arranged in the circulating pipe II 19. The liquid at the bottom of the auxiliary tank body 18 is pumped by a pump II 20 to the top and falls down to form a circulation.
A connecting pipe 21 is arranged between the main tank body 5 and the circulating pipe II 19, chlorine gas which is not absorbed in the main tank body 5 is communicated into the circulating pipe II 19 through the connecting pipe 21, and the chlorine gas is mixed and reacted with waste liquid in the circulating pipe II 19.
Similarly, the distance between the connecting point of the connecting pipe 21 and the circulating pipe II 19 and the connecting point of the circulating pipe II 19 and the top of the auxiliary tank body 18 is more than 20cm, so that chlorine gas is subjected to flowing mixing of more than 20cm after being initially mixed with the circulating pipe II 19, and the chlorine gas is more fully reacted. The connecting point of the connecting pipe 21 and the circulating pipe II 19 is positioned above the connecting point of the circulating pipe II 19 and the top of the auxiliary tank body 18, so that chlorine gas stays in the waste liquid for a longer time to be fully reacted.
The circulating pipe II 19 on the secondary tank 18 is also connected with a feeding pipe 26 for guiding the liquid in the secondary tank 18 into the main tank 5 to be in contact reaction with the chlorine to a greater extent.
In this case, the circulating pipe II 19 is not provided with a temperature reducing mechanism, which takes into account that only a small part of chlorine gas is introduced into the auxiliary tank 18 through the connecting pipe 21, and the heat generated by the reaction is not much. In other embodiments, a cooling mechanism may be further provided in the circulation pipe ii 19.
In this example, the sub-tank 18 is further provided with a chlorine gas discharge pipe 22 for discharging a very small portion of the unreacted chlorine gas. The chlorine gas discharge pipe 22 is connected to a gas treatment module 24 (see fig. 2).
The circulating pipe I6 on the main tank body 5 is also connected with a finished product output pipe 27, and the feeding end of the finished product output pipe 27 is connected with the circulating pipe I6 and used for leading out liquid containing ferric trichloride after waste liquid in the main tank body 5 fully reacts with chlorine.
In this example, two main tanks 5 are provided, and correspondingly, two circulation pipes ii 19 are provided in the auxiliary tank 18. Connecting pipes 21 are connected between the main tanks 5 and the circulating pipes II 19 in one-to-one correspondence, and chlorine gas that is not absorbed in the two main tanks 5 is absorbed by the same auxiliary tank 18. This is an efficient use of the secondary tank 18, since only a small part of the unreacted chlorine in the main tank 5 is passed into the secondary tank 18 via the connecting pipe 21. The main tank 5 can also be provided in greater numbers and likewise with a secondary tank 18. Of course, in the case of two main tanks 5, it is also possible to provide only one circulation pipe II 19 on the auxiliary tank 18, connecting the two connection pipes 21 to the same circulation pipe II 19. In this embodiment, the number of the circulating pipes II 19 is set to correspond to the number of the main tank 5, i.e., two circulating pipes II 19 are provided, which is beneficial to fully absorbing chlorine.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
