Aeration chlorine dioxide generator

Abstract

The invention discloses an aeration chlorine dioxide generator, comprising a water supply system for providing water for reaction, and a reaction system for synthesizing chlorine dioxide, wherein the water supply system is communicated with a reactor of the reaction system, the reactor comprises a reactor body and an aeration pipeline assembly, the reactor body comprises a plurality of reaction chambers communicated in sequence, the reaction chamber at one end is communicated with a raw material supply device, the reaction chamber at the other end is communicated with a waste liquid outlet, each reaction chamber is communicated with a product outlet, the aeration pipeline assembly is communicated with each reaction chamber. The chlorine dioxide generator adopts multilevel plug flow reaction (such as four-level plug flow reaction) and multistage aeration process, so the reaction is more thorough, and residual liquid after reaction can be discharged after being up to standard.

Description

technical field [0001] The invention belongs to the field of chlorine dioxide synthesis, and in particular relates to an aeration type chlorine dioxide generator. Background technique [0002] Chlorine dioxide is a new generation of broad-spectrum fungicide and high-efficiency oxidant, which has been widely used in various water treatments. In developed countries such as Europe and the United States, chlorine dioxide has gradually become a substitute for chlorine disinfection of drinking water. Compared with other disinfectants, chlorine dioxide has the following obvious advantages: broad-spectrum, high efficiency, not affected by pH value and ammonia concentration in water, especially does not produce disinfection by-products with organic matter in water, so that three halogens in disinfected water The content of methane is greatly reduced, making it a safe and efficient disinfection product in water treatment. [0003] At present, chlorine dioxide generators generally in...

AI Technical Summary

Problems solved by technology

The current chlorine dioxide generator also has the following disadvantages: 1. After the traditional raw material liquid enters the generator, the mixing is not timely, or because the reaction needs to reach a certain temperature to proceed, after the raw material liquid enters the reactor, the heating rate is relatively slow. Slow, resulting in slow reaction speed, affecting production efficiency, resulting in substandard reaction yield; 2. In the case of unstable pressure in pipelines or equipment containers, the flow rate of the metering pump is difficult to stabilize, and fluctuations will occur, which will affect the 3. The structure of the traditional chlorine dioxide generator is scattered and inconvenient to install; 4. The traditional chlorine dioxide generator has no judgment function when there is no liquid medicine. Our company's equipment has a cut-off alarm function. When there is no liquid medicine, a cut-off signal will be sent, and the machine will automatically alarm and stop
