The pickling time of the process in the above patent is short and can prevent the acid mist from volatilizing, but it needs to be soaked in clean water before pickling, which wastes water and is not convenient for the pre-reaction of rusted objects, and it is not convenient to use the pickling process to remove impurities from the acid solution Reuse

The invention discloses a process for treating waste sulfuric acid on the surface of a metal kayak support. The process comprises the following steps: 1, acid mist dust removal is conducted, specifically,a metal kayak support is placed in an acid pickling box, and acid mist in the acid pickling box is sprayed to the surface of the metal kayak support in a pressurized manner by using a spraying device in the acid pickling box to obtain a first metal kayak support; 2, pickling is conducted, specifically, the first metal kayak support is soaked in acid liquor, and a second metal kayak support is obtained after soaking is completed; 3, high-pressure acid pickling is conducted, specifically, acid liquor in the acid pickling box is sprayed to the surface of the second metal kayak support in a pressurized mode through a spraying device, and a third metal kayak support is obtained; and 4, rotational flow acid pickling is conducted, specifically, the third metal kayak support is placed in a cyclone shell, acid liquor in the acid pickling box enters the cyclone shell in the tangential direction to form rotational flow to clean the outer surface of the third metal kayak support, and a finished product is obtained. The invention provides a treatment process which is convenient for pre-reaction of rusted substances, convenient for impurity removal and reutilization of acid liquor by using an acid pickling process, energy-saving and environment-friendly.
Description
technical field [0001] The invention mainly relates to the technical field of metal surface treatment, in particular to a process for treating waste sulfuric acid on the surface of metal kayak supports. Background technique [0002] The scale and rust on the metal surface can be removed by using waste sulfuric acid. This treatment method is called pickling. [0003] According to the pickling process of welding wire steel surface pretreatment provided by the patent literature with application number CN201710361303.X, the process includes the following steps: a. Immerse the welding wire steel in clear water with a temperature of 55-60 degrees for 5-8 minutes ; b, configure the above pickling solution, inject the pickling solution into the pickling tank; c, place the welding wire steel material soaked in clear water in the pickling tank for pickling, the pickling temperature is 20-35 degrees, The pickling time is 30-40 minutes; d, the pickled welding wire steel is washed with ...
