Description
Technical Field
The invention relates to a plasma environment-friendly treatment method of polychlorinated biphenyl waste liquid.
Background
The phenyl silane monomer is an important organic silicon compound, can be used for the production of phenyl silicone oil, phenyl silicone resin and phenyl silicone rubber, and has very important value for high and new industries and national defense industries. The main synthetic method of the phenyl silane monomer is to synthesize phenyl chlorosilane at high temperature by using chlorobenzene and silicon powder under the action of catalysts such as copper powder and the like, and synthesize the phenyl silane monomer by processes such as alcoholysis and the like. In the process, high-boiling organic residual liquid containing silicon powder, copper powder, carbide and a large amount of polychlorinated biphenyl is generated.
Polychlorinated biphenyl is a general name of a class of artificially synthesized chlorinated biphenyl compounds, can be combined into 209 isomers theoretically according to different substitution numbers and substitution positions of chlorine atoms, has relatively similar molecular structure and physicochemical properties of homologous bodies, is very stable, is not easy to decompose, does not react with chemical substances such as acid, alkali and the like, is extremely difficult to dissolve in water, has very strong affinity to lipids, and is extremely easy to enrich in fat of organisms. At normal temperature, the polychlorinated biphenyl is heavier than water, has stable physicochemical properties, can exist in the environment for a long time once entering the environment, is very difficult to degrade (the half-life period of the polychlorinated biphenyl reaches about 40 years), and has a long panning time in the environment. Polychlorinated biphenyls cannot be degraded at an appreciable rate in the environment by hydrolysis or similar reactions, only a small fraction is converted by bio-enzyme action in soil and photolysis by sunlight ultraviolet, contaminated water and soil are also difficult to recover, and there is a high residue in the environment. Animal experiments show that the polychlorinated biphenyl has an induction effect on pathological changes and even canceration of skin, liver, gastrointestinal system, nervous system, reproductive system and immune system.
The harm of polychlorinated biphenyl is gradually recognized in the fifties to seventies of the last century abroad, and management policies are made to control and gradually eliminate the pollution caused by the polychlorinated biphenyl. The polychlorinated biphenyl waste liquid has high organic matter content and high heat value; the toxicity is high, and the environmental pollution is serious; difficult degradation, and difficult treatment by the conventional method; complex components, great difficulty in harmlessness and the like. Conventional physical treatment, chemical treatment, physical chemical treatment, biological treatment and the like are difficult to treat and can be treated only by incineration. Meanwhile, the traditional incineration process uses open fire to incinerate the waste liquid containing slag, and because the flame temperature can only reach about 1000 ℃, the waste liquid such as silicon powder, copper powder and the like in the waste liquid can be melted at the temperature, but the fluidity is poor, so the waste liquid is difficult to discharge out of the incinerator and is difficult to treat.
Disclosure of Invention
In order to overcome the defects, the invention provides a plasma environment-friendly treatment method of polychlorinated biphenyl waste liquid without pollutant discharge, which comprises the following steps:
(1) cracking raffinate:

(2) carrying out waste heat recovery on tail gas discharged from a secondary combustion chamber and then quenching and collecting dust;
(3) and washing and discharging tail gas.
Preferably, in the step (1), the plasma arc furnace and the plasma cracking tubular reactor both use water vapor as an arc starting medium and use water vapor as a plasma working medium, so that the cost is low, a part of H, O elements required by element compatibility can be provided, and the generation of nitrogen oxides can be avoided. In the step (1), water vapor is added into a high-temperature area of the plasma cracking tubular reactor, so that H, O elements are obtained for element compatibility.

The liquid seal pipe for setting the slag in the step (1) has two purposes, namely the purpose of realizing the isolation between the inside and the outside of the hearth and the purpose of continuously and stably discharging the slag. The plasma furnace chamber is always in negative pressure during working, and the liquid seal can separate media inside and outside the furnace chamber.
Preferably, the tail gas from the second combustion chamber in the step (2) is subjected to waste heat recovery by a waste heat recovery device, then is cooled to 580-620 ℃, is instantly cooled to 180-200 ℃ by a spray quencher, and enters a bag type collector for dust collection. The aim of quenching is to avoid the generation of dioxin, and secondly, for dry dust collection, the tail gas from the spray quenching tower is cooled to 180-200 ℃, at the moment, the water in the tail gas still exists in the form of superheated water vapor, and the nano-scale silicon dioxide in the tail gas is suspended in the tail gas in the form of solid due to small particle size, and directly enters the bag-type collector, and then the nano-scale silicon dioxide in the tail gas is collected to be sold as a byproduct white carbon black.
In the process, the waste heat recovered by the waste heat recoverer can be used for preheating raw materials and can also be used for preheating air supply of a secondary combustion chamber, and if the amount of residual liquid is large, a waste heat boiler can be arranged for recovering heat in a low-pressure steam mode.
Preferably, the tail gas in the step (3) is discharged from a chimney after being sequentially subjected to water washing and alkali washing, and the dust in the tail gas is supplemented by a bag type collector, so that hydrochloric acid generated by absorbing hydrogen chloride in the water washing process is clear and transparent and can be sold as a byproduct.
The invention has the beneficial effects that:
1. the invention reduces the content of nitrogen oxide in the tail gas, also reduces the ineffective heat and improves the productivity;
2. the glass powder is added into the plasma arc furnace, so that the fluidity of the slag and the discharge amount of the slag can be increased, the slag is ensured to be discharged in a flowing manner all the time, the blockage of a slag discharge port caused by cooling due to intermittent slag discharge is prevented, and the discharged molten slag can form a stable glass body after being cooled, so that no pollution is caused;
3. the method is suitable for treating the waste liquid with high chlorine content, the residual liquid is decomposed more thoroughly, and the content of dioxin is extremely low;
4. the whole treatment process has large elasticity, and the residue content, chlorine content and silicon content of the residual liquid are not limited and can be treated harmlessly.
