[0028] As Figure 1 The quantitative production low-concentration acid device of the embodiment comprises:

[0029] The raw material box 1 is used for containing solid raw materials, and the solid raw materials are powdery materials.

[0030] The conveying column pipe 2 is connected with the outlet of the raw material box 1 and is used for conveying the solid raw materials; the powdery raw materials enter the conveying column pipe 2 from a plurality of branch pipes arranged in a plane or in a ring, and the conveying column pipe 2 is provided with a plurality of reaction holes 21 on the surface.

[0031] The reaction chamber 3 is wrapped around the conveying column pipe 2 and is provided with a water inlet 31 on one side, an acid outlet 32 on one side and a dosing port 33 on one side; the liquid added through the dosing port 33 and the water inlet 31 enters the reaction holes 21 and reacts with the solid raw materials.

[0032] The circulation pipe 4 is arranged between the acid outlet 32 and the water inlet 31. The liquid circulation driven by the circulation pipe 4 can make the liquid distribution uniform, and then improve the reaction efficiency.

[0033] The circulation pipe 4 is provided with a heat tracing band 5 on the side close to the acid outlet 32. The heat tracing band 5 is provided with a heating element outside the circulation pipe 4, and the heat tracing band is a common pipeline heating and heat preservation equipment. The circulation pipe 4 is heated by the heat tracing band 5, and the principle of heat rising and cold flow descending is used. The substandard acid enters the circulation pipe and returns to the bottom of the reactor for reaction again. The circulation arrangement strengthens the uniform flow of the acid liquid, maintains the activity of the bacterial strain, and discharges the qualified acid through the outlet. In order to ensure smooth flow, a pump structure can be additionally arranged in the pipeline to ensure the flow of the liquid. Valves are arranged at the corresponding positions of the pipeline to control the flow direction of the materials.

[0034] The reaction chamber 3 is provided with a sewage outlet 34. After the production of a single acid reaction is completed, the reaction chamber can be flushed with water, and then discharged from the bottom sewage outlet 34. After flushing, another kind of acid can be produced by adding medicine again. The same equipment can be used multiple times, saving equipment costs. The bottom sewage outlet 34 includes two, one is connected with the lower outlet of the tube, and the other is the outlet of the reaction chamber 3, which is used to empty the reaction chamber 3 and the material in the tube.

[0036] The acid outlet 32 is provided with a pH sensor 35. The pH sensor 35 detects the liquid pH of the acid outlet 32. If it does not meet the standard, it will enter the circulating pipe 4.

[0037] The reaction chamber 3 is a flat structure or a cylindrical structure. The flat structure refers to a square structure, but the square flat structure with a smaller thickness is used to place the flatly arranged column tubes. The cylindrical structure is used to place the column tube structure arranged in a ring shape.

[0038] In use, first, the raw materials are put into the raw material box 1, and the raw materials are released to enter the delivery column tube 2. Water is added to the reaction chamber 3 through the water inlet 31, and nutrient solution is added to the inside through the medicine inlet 33. If the raw materials are sulfur powder and corresponding bacterial spores, the bacterial spores are activated by mixing with the nutrient solution, and the acid production starts. After the solid raw materials are dissolved, the medicine in the top raw material box 1 falls into the column tube. When the pH reaches the set value, the acid is discharged. If it does not meet the standard, the material is circulated by heating with the heating belt, and the temperature is increased to promote the reaction, so as to improve the reaction rate.
