Rather, these embodiments are provided so that the present application is more thoroughly and completely conveyed to those skilled in the art, and so that the scope of the present application is fully conveyed to those skilled in the art.

[0028] As shown in Figure 1 A saturator with mother liquor storage tank, comprising:

[0029] A saturator body 1, the upper end of the saturator body 1 is provided with a liquid feeding pipe 7 and an overflow pipe 3, and the lower end of the saturator body 1 is provided with a liquid discharging pipe;

[0030] A liquid storage tank 2, the upper end of the liquid storage tank 2 is connected with the overflow pipe 3, and the cleaning liquid submerges the full-flow tank core 6 of the saturator during overflow, and the lower end of the liquid storage tank 2 is provided with a second liquid discharging pipe 5;

[0031] A circulating mechanism, the input end of the circulating mechanism is connected with the first liquid discharging pipe 4 and the second liquid discharging pipe 5, and the output end of the circulating mechanism is connected with the liquid feeding pipe 7.

[0032] Specifically, the original drop flushing is changed into soaking cleaning by the saturator body 1 in combination with the liquid storage tank 2, the cleaning effect is improved, and the first liquid discharging pipe 4 can discharge the dirt and impurities that fall off and empty the cleaning liquid in the saturator, so as to avoid the accumulation of impurities. At the same time, the liquid storage tank 2 has large capacity, and can be used for multiple saturators after one-time dispensing or for long-time use of a single saturator.

[0033] Further, the liquid storage tank 2 has large capacity, can provide the effect of standing, sedimentation and filtration, and guarantees the cleanliness of the cleaning liquid, and the first liquid discharging pipe 4 can be a self-contained liquid discharging pipe of the saturator.

[0034] In the present embodiment, the first liquid discharging pipe 4 is provided with a first operation valve.

[0035] Specifically, the flow of the first liquid discharging pipe 4 is controlled by the first operation valve.

[0036] Further, the first liquid discharging pipe 4 can be closed by five percent for improvement of the original liquid discharging pipe.

[0037] In the present embodiment, the second liquid discharging pipe 5 is provided with a second operation valve.

[0038] Specifically, the flow of the second liquid discharging pipe 5 is controlled by the second operation valve, so as to facilitate the control of the concentration of the cleaning liquid during liquid dispensing.

[0039] In the present embodiment, the liquid feeding pipe 7 is connected with a water supplement pipe.

[0040] Specifically, water is supplied to the saturator through the water supply pipe, and a large concentration of acidic cleaning solution is used.

[0041] In this embodiment, the liquid storage tank 2 is provided with a filtering mechanism.

[0042] Specifically, the impurities in the inclined liquid are filtered through the filtering mechanism.

[0043] In this embodiment, the liquid storage tank 2 is provided with a dispensing port.

[0044] Specifically, the concentration is controlled by supplementing the liquid medicine or neutralizing liquid through the dispensing port.

[0045] In this embodiment, the saturator body 1 is provided with multiple saturators, and the multiple saturator pump bodies share one liquid storage tank 2.

[0046] Specifically, one liquid storage tank 2 supplies multiple saturators, eliminating the need for each team to configure cleaning solution every day, reducing the labor burden.

[0047] In this embodiment, the liquid storage tank 2 is provided with multiple second liquid discharge pipes 5.

[0048] Specifically, each second liquid discharge pipe 5 corresponds to each saturator. The corresponding second liquid discharge pipe 5 is opened for circulating immersion cleaning when a saturator is cleaned.

[0049] In this embodiment, the flow rate of the first liquid discharge pipe 4 is less than that of the overflow pipe 3.

[0050] In this embodiment, the circulating mechanism includes a circulating pump.

[0051] Specifically, the cleaning solution is recycled by the circulating pump.

[0052] This embodiment is a saturator with a mother liquor storage tank in use, which is improved for single saturator use:

[0053] Before the modification, the secondary spraying pump (circulating pump) sends the saturator mother liquor through the full-flow tank to the upper part of the saturator for gas purification, and the mother liquor in the lower cavity is pumped to the middle part of the saturator by the large mother liquor pump. The mother liquor flows to the lower cavity of the saturator through the descending pipe, which is prone to blockage and increase the system resistance during long-term operation. After the saturator discharges, the mother liquor needs to be supplemented, and the amount of supplement during this process is relatively small. With the operation of the equipment, the saturator may have difficulty in descending pipe and high resistance, which requires large amounts of acid and water for treatment, affecting the production of ammonium sulfate, and the trace impurities in the gas affect the quality of ammonium sulfate after long-term operation.

[0054] During the modification, a liquid storage tank 2 is arranged near the saturator, an overflow pipe 3 connected with the liquid storage tank 2 is additionally arranged at the upper end of the saturator, and a second liquid discharge pipe 5 is connected to the circulating mechanism at the lower end of the liquid storage tank 2, like the first liquid discharge pipe 4 of the saturator.

[0055] When using, the opening of the first operation valve is regulated, the cleaning liquid enters the saturator from the top, fills the inner wall and soaks the flume core 6. Part of the cleaning liquid circulates through the overflow pipe 3 and the liquid storage tank 2, and part of the cleaning liquid circulates through the first liquid discharge pipe 4.

[0056] The modified liquid storage tank 2 is equivalent to a large full flume and is added to the system circulation. Because the liquid storage tank 2 is large, one batch of mother liquor can run for six shifts, and the original running mode can be changed back when the mother liquor is prepared, so that the ammonium sulfate production is basically not affected. When the resistance of the saturator is too large and the saturator needs to be cleaned, the acidity of the liquid storage tank 2 can be increased, and a large amount of water can be added to the saturator body 1, so that the ammonium sulfate production is basically not affected. At the same time, the liquid storage tank 2 plays a role in standing and precipitating in the production process to improve the quality of ammonium sulfate and reduce the frequency of the downcomer blockage.

[0057] The above has described the various embodiments of the present application, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments.
