Problems solved by technology

This method requires relatively complicated installations, since the gases produced have to be specially processed through washing columns
[0008] Also, regardless of the method employed, it appears that the properties of the liquid may vary significantly not only due to heat release but also due to compatibility with the material chosen to make the reactor

Embodiment Construction

[0095] I. Device

[0096] figure 1 An example is provided for the description provided below. The invention is based on the use of an arc-blowing plasma ( 1 ) submerged in a cylindrical reactor with a volume of 50 L filled with water ( 2 ). The liquid product ( 3 ) to be treated, eg a mixture of phosphorus-containing hydrocarbons, is introduced into the plasma through a channel system provided in the oxygen-operated torch. Once in the plasma, the liquid is instantaneously raised to very high temperatures of the order of 2000°C in the presence of oxygen, with the consequence of complete destruction (destruction) of the organic matter.

[0097] figure 2 The plasma torch used is illustrated. This is a conventional plasma torch in which a tungsten refractory cathode (10), conical, protected by an argon flow (12), produces an arc towards the anode (11). The anode (11) comes in the form of a sheath 10 cm in length and 10 mm in diameter. This arc is blown by argon (12) and o...

Abstract

The present invention relates to a method for treating a liquid solution S1 including a step of injecting said liquid solution S1 into a plasma immersed in a second liquid solution S2, which is separate from said liquid solution S1. The invention also relates to a device capable of being implemented in the context of such a method.

Description

technical field [0001] The invention relates to the field of treatment of waste, advantageously liquid chemical waste. [0002] More specifically, the present invention proposes a method of treating chemical wastes based on the destruction of these wastes by injecting them directly into a plasma submerged in a reactor filled with a liquid such as water. [0003] The invention also relates to a device (device) that can be used within the scope of the method. Background technique [0004] Today the treatment of any type of liquid waste such as hazardous and / or radioactive organic liquids is done by thermal processes using furnace type reactors which may be heated in different ways and have different properties such as static furnaces or converters. [0005] Therefore, the methods of treating wastes all use thermal units connected to gas treatment systems of relatively large dimensions, ensuring cooling, filtering and neutralization of certain elements such as chlorine. This ...
