Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the acid supply method of invention is described further.

[0022] Such as figure 2 As shown, in the acid supply method of the present invention, each acid storage tank 1, 2, 3 is equipped with an acid adjustment pump 4, which is connected with the acid adjustment bucket 5 on the second floor, realizing three acid storage tanks 1, 2, 3 independent acid supply. The acid adjustment barrel 5 supplies the adjusted acid solution into the small acid barrel through the control of the valve 6. When one of the acid adjustment pumps or pipeline fails, one or both of the remaining two can be selected for use without shutting down. The pipelines in the acid supply method all use 316L stainless steel pipes. The 316L stainless steel pipes have good anti-acid and anti-corrosion functions, which can effectively prevent acid leakage after the acid circuit is corroded. Exhaust pipes are installed at the highest point of the three pipeli...

Abstract

The invention discloses an acid supplying method, which comprises acid storage tanks (1,2 and 3), acid adjusting pumps (4), an acid adjusting barrel (5) and a small acid barrel (7), wherein each of the acid storage tanks (1, 2 and 3) is singly provided with the acid adjusting pump (4), and the acid adjusting pumps (4) are connected with the acid adjusting barrel (5) to achieve the independent acid supply of the acid storage tanks (1,2 and 3). The highest point of an acid supplying pipeline of each of the acid storage tanks (1, 2 and 3) and the highest point of the acid adjusting barrel (5) are provided with exhaust pipes (9). The acid supplying method completely eliminates the phenomenon of acid pipeline gas block, eliminates the phenomenon that the acid pipeline is corroded easily, reduces the acid consumption and greatly reduces the investment of labor and material resources.

Description

technical field [0001] The invention belongs to the field of pulp pipeline transportation, in particular to an acid supply method for cleaning a ceramic filter. Background technique [0002] Nitric acid is one of the important chemical raw materials with a wide range of uses, and can be widely used in fertilizer, national defense, metallurgy, chemical fiber, chemical industry, dyestuff, pharmaceutical and other industries. It is a transparent, colorless or yellowish corrosive liquid with a unique suffocating odor, which decomposes into nitrogen dioxide with a pungent odor when exposed to moisture or heat. Nitric acid is chemically active and can react with many substances. It is a strengthening agent that can corrode various metals and materials (except aluminum and special chromium alloy steels). [0003] In the pipeline transportation of ore pulp, the dehydration station is mainly responsible for dehydrating the ore pulp transported from the remote end through the pipelin...
