[0026] like Figure 1 to Figure 2 As shown, the acid-base medium spray waste gas treatment system of the utility model includes: a spray tower 1 and a dosing barrel 2, the dosing barrel 2 is connected to the spray tower 1 through a circulating pump 3, and the bottom of the spray tower 1 is connected to the dosing barrel 2; an automatic liquid replenishing component, the automatic liquid replenishing component is connected to the dosing barrel 2, so that: when the spray medium in the dosing barrel 2 is lower than the threshold value, the spray medium in the dosing barrel 2 can be automatically replenished; a liquid storage tank 4, the liquid storage tank 4 at least surrounds the area where the spray tower 1 and the dosing barrel 2 are located.

[0027] See also Figure 1There is a spray head inside the spray tower 1, an air inlet is formed on the spray tower 1, and an air outlet is formed on the top. The exhaust gas enters the spray tower 1 through the air inlet to the space below the spray head. The spray medium sprayed by the spray head can effectively purify the exhaust gas, and the purified exhaust gas is discharged into the atmosphere through the air outlet.

[0028] See also Figure 1 The spray head in the spray tower 1 is connected to the outlet of the circulation pump 3 through a pipeline, the lower part of the spray tower 1 is connected to the lower part of the dosing barrel 2 through a pipeline, and the inside of the dosing barrel 2 is connected to the inlet of the circulation pump 3 through a pipeline; the acid and alkali spray medium in the dosing barrel 2 is pumped to the spray head through the circulation pump 3, and after the acid and alkali spray medium sprayed from the spray head purifies the exhaust gas, the spray medium flows to the bottom of the spray tower 1 and flows back to the dosing barrel 2 through the pipeline, thereby forming a cycle.

[0029] See also Figure 1 The automatic liquid replenishing component is connected to the dosing barrel 2 through a pipeline. When the spraying medium in the dosing barrel 2 is lower than the threshold value, the liquid replenishing operation can be automatically performed; the replenished liquid can be water or a configured acid-base spraying medium; when the replenished liquid is water, solid chemicals need to be added to the dosing barrel 2 to form an acid-base spraying medium in the dosing barrel 2.

[0030] See also Figure 1 In order to facilitate the staff to add medicine to the dosing barrel 2, the top of the dosing barrel 2 is generally not provided with a cover, or a cover that does not seal the dosing barrel 2 is provided; however, when the spray system or the automatic liquid replenishing component fails and causes the spray medium in the dosing barrel 2 to leak, the spray medium will flow into the liquid storage tank 4 that surrounds the spray tower 1 and the dosing barrel 2. By configuring the liquid storage tank 4, the leaked acid and base chemicals can be collected to avoid the diffusion of acid and base chemicals, thereby improving the safety of the spray tower 1 in treating waste gas and having practicality.

The pipelines connecting the collecting buckets 52 are relatively located above the side of the collecting bucket 52. Through this arrangement, the use of the collecting buckets 52 can be reduced as much as possible, so that after one collecting bucket 52 is filled with acid-base medium, it will flow to the next collecting bucket 52, which is convenient for the staff to recover the acid-base medium.

[0033] In one or more embodiments, the collection bucket 52 is located outside the liquid storage tank 4. This arrangement can reduce the contamination of the outside of the collection bucket 52 by the acid-base medium, and reduce the number of operations for the staff to clean the outside of the collection bucket 52. In other possible embodiments, the collection bucket 52 is configured inside the liquid storage tank 4; this arrangement can reduce the occupied space of the present application.

[0034] In one or more embodiments, the water pump 51 is located at the lowest position in the liquid storage tank 4. Through this arrangement, the water pump 51 can maximize the extraction of the acid-base medium in the liquid storage tank 4, reduce the residue of the acid-base medium, and further avoid the problem of the volatilization of the acid-base medium affecting the ecological environment.
