Embodiment Construction

[0021] There are many options for two-component solutions, commonly used are sodium chlorate and hydrochloric acid, or sodium chlorite and hydrochloric acid, and sodium hypochlorite.

[0022] The main raw material of this product (agent) is sodium chlorite. It is formulated with stabilizers and passivators, easy for long-term storage and safe for transportation. When used, agent A is ≥ 2% stable solution, agent B is ≥ 5% special activation solution, and the concentration of the solution obtained through the reaction system is 20000ppm. It only needs to be controlled at 0.2-0.5ppm for each ton of water added to tap water to achieve the sanitary calibration formulated by the state, and the B agent product is directly distributed without the need to purchase additional accessories that match the present invention—the dosing device makes users feel safe and convenient.

Abstract

The invention relates to a chlorine dioxide feeding method. Two raw materials for reaction to prepare chlorine dioxide, i.e. a first reactant and a second reactant, are added into a measurement type dissolving tank and are then mixed to prepare a two kinds of solution of the nominal concentrations, the concentration of the solution containing chlorate A is more than or equal to 2 percent, the concentration of the solution containing chlorate B is more than or equal to 5 percent, the two kinds of solution are directly and accurately proportioned or are transferred into a storage tank to be accurately proportioned through a metering pump after preparation and are then transferred into a chlorine dioxide generator for reaction, and finally the two kinds of solution are added into a reactor reception tank for reaction or into a reaction coil for full reaction. When the two kinds of solution are added into the reactor reception tank, the mixture can be added through air. The prepared chlorine dioxide is discharged out of the reactor in the gas form, and can be directly added into water to be treated or added into water to be treated after absorption by an absorbent material.

Description

technical field [0001] The invention relates to a dosing method and special equipment after chlorine dioxide is prepared by binary methods such as acid and chlorate. Background technique [0002] Chlorine dioxide is prepared by typical sodium chlorate method, ihey involves the application of disinfection and bleach, and it is an industry with more and more applications. For example, chlorine dioxide is prepared from hydrochloric acid and sodium chlorate and used for water treatment, especially for the treatment of tap water, swimming pools and hospital wastewater, which has been gradually promoted. Another example is to use potassium chlorate, oxalic acid and sulfuric acid (sodium chlorate or sodium chlorite and hydrochloric acid) as raw materials, mix the reactants uniformly and then react under negative pressure at 20-80°C, and the chlorine dioxide gas produced can be Use directly or absorb with sodium percarbonate solution to make stable chlorine dioxide solution. When ...
