专利汇可以提供Controlling concentration of oxidizing agent in deodorizing process专利检索,专利查询,专利分析的服务。并且PURPOSE: To effect automatic periodic electrode cleaning in wet type deodorizing operation of bad odor gas by a method wherein NaClO concentration in absorption liquid is specified by control circuit of convectional voltammetry including a potentiostat and a function generator.
CONSTITUTION: Bad odor gas 1 is guided into an absorption tower 2, treated with liquid in an acid tank 4, and made in contact with absorption liquid in tank 5, adjusted to a 0.001W1% NaClO concentration, then discharged as deodored gas. The concentration adjustment is made so that circulation line 6 is given by-pass pipe 7 having a NaClO meter 8 incorporating a work electrode to cathodize ClO
- , a reference electrode (e.g. silver-silver chloride electrode) to set potential, and an opposite electrode (Pt) to flow current. Also, an automatic indication adjuster 9 incorporating potentiostat, function generator, sequence unit to control cycle is installed, so that current detected from work electrode is set and controlled to have NaClO concentration fall in the above range. By indication of the adjuster 9, a chemical injection pump 10 is actuated and chemical 11 is supplied.
