Embodiment approach

[0054] As a preferred embodiment of the present invention, comprising the following steps:

[0055] Atomization treatment: First, part of the liquid to be treated is atomized to obtain droplet particles;

[0056] Reaction with plasma: the mist particles are mixed with the plasma to form a gas-liquid mixture, and the product obtained after the plasma in the gas-liquid mixture reacts with the mist of the liquid to be treated is dissolved in the remaining liquid to be treated;

[0057] The steps of atomization and reaction with plasma are repeated until all the liquid to be treated is treated.

[0058] Repetition can make the reaction between the liquid to be treated and the plasma more sufficient, and the circulation can be completed in the same container, which is beneficial to save equipment cost.

[0059] As a preferred embodiment of the present invention, the size of the droplet particles obtained after the liquid to be treated is atomized is 0.2-200 microns.

[0060] As a...

Embodiment 1

[0066] A plasma treatment method for chemical liquid, comprising the following steps:

[0067] Step a): atomize part of the liquid to be treated first to obtain liquid droplet particles with a size of 0.2-30 microns;

[0068] Step b): Mixing the droplet particles with plasma (plasma generated by the excitation of air in the plasma generator) to form a gas-liquid mixture, the plasma in the gas-liquid mixture reacts with the liquid to be treated in the droplet particles to obtain The product is dissolved in the remaining liquid to be treated;

[0069] Step a) and step b) are repeated until all the liquid to be treated is completely treated, thereby realizing the treatment of the liquid.

[0070] In this embodiment, the liquid to be treated is sewage. The plasma generated in the above-mentioned plasma generator reacts with the organic matter in the mist particles of the sewage to generate harmless substances such as water or carbon dioxide, so as to achieve the purpose of remov...

Embodiment 2

[0072] A plasma treatment method for chemical liquid, comprising the following steps:

[0073] Step a): atomize part of the liquid to be treated first to obtain liquid droplet particles with a size of 30-110 microns;

[0074] Step b): Mixing the droplet particles with plasma (plasma generated by the excitation of air in the plasma generator) to form a gas-liquid mixture, the plasma in the gas-liquid mixture reacts with the liquid to be treated in the droplet particles to obtain The product is dissolved in the remaining liquid to be treated;

[0075] Step a) and step b) are repeated until all the liquid to be treated is completely treated, thereby realizing the treatment of the liquid.

[0076] In this embodiment, the liquid to be treated is sewage. The plasma generated in the above-mentioned plasma generator reacts with the organic matter in the mist particles of the sewage to generate harmless substances such as water or carbon dioxide, so as to achieve the purpose of remov...

Abstract

The invention provides a chemical liquid plasma treatment method and equipment and relates to the technical field of chemical liquid treatment. The method includes following steps: atomizing to-be-treated liquid; mixing with plasma to form a gas-liquid mixture, wherein the plasma in the gas-liquid mixture reacts with mist drops of the to-be-treated liquid to realize liquid treatment. The equipment comprises a container for containing the to-be-treated liquid, the container is provided with a liquid inlet, a liquid outlet and a gas inlet for being communicated with a plasma generator, the container is connected with an atomizer for atomizing the to-be-treated liquid, the liquid outlet is communicated with the liquid inlet through a circulating pipeline, and a circulating pump is arranged on the circulating pipeline. By utilizing the chemical liquid plasma treatment method and equipment, the technical problems of high power consumption, high heat conversion rate, high investment cost and low reaction efficiency when plasma is used to treat liquid in the prior art are relieved, and lowering of power consumption and improving of reaction efficiency are realized.

Description

technical field [0001] The invention relates to the technical field of chemical liquid treatment, in particular to a chemical liquid plasma treatment method and equipment. Background technique [0002] Plasma is the fourth state of matter, which is an ionized gas composed of a large number of free electrons and ions, and is generally electrically neutral. Plasma can generate a large number of OH·free radicals during discharge, and OH·free radicals can induce a series of free radical chain reactions, which can then be applied to sewage treatment. OH free radicals have large-scale chain reaction capabilities, react quickly and without selectivity, can attack various pollutants in water, degrade them into carbon dioxide, water or other mineral salts, can effectively remove organic matter in sewage, and do not There will be secondary pollution. Some chemical reactions that cannot be carried out under "three-state" conditions can be carried out in the plasma state. Plasma trea...
