Problems solved by technology

[0004] The current plasma technology adopts the method of completely plasmaizing the substances when dealing with various substances to form simple small gas molecules (such as hydrogen, carbon monoxide, etc.). This method has the problem of overtreatment, which not only wastes a lot of energy, but also Plasma all the useful substances into small molecular gases, without maximizing the utilization of resources

Embodiment 1

[0038] Anthracene-containing organic waste enters the feed pipe through the raw material pump, is heated by the steam jacket to 90°C, and reaches the distributor after being mixed with the additive at the end of the feed pipe; the additive is methanol, and the molar ratio of the additive to the organic waste is 1 :1;

[0039] The temperature in the plasma reaction chamber is controlled at 750°C. The anthracene in the organic waste breaks bonds and combines to form naphthalene, benzene and carbon monoxide, and completes partial plasmaization. The solid matter generated by the reaction of naphthalene, benzene and other components of the organic waste undergoes plasma reaction After the lower part of the device is cooled down to 150°C, it is discharged from the bottom material outlet to the material storage tank. The reaction formula of the above process is as follows:

[0040]

Embodiment 2

[0042] The organic waste containing benzofluorene enters the feed pipe through the raw material pump, is heated by the steam jacket to 92°C, and reaches the distributor after being mixed with the additive at the end of the feed pipe; the additive is methanol, and the molar ratio of the additive to the organic waste is 1:1;

[0043] The temperature in the plasma reaction chamber is controlled at 780°C. The benzofluorene in the organic waste breaks bonds and combines to form naphthalene, benzene (or toluene) and carbon monoxide, and completes partial plasmaization. Naphthalene, benzene (or toluene) and other organic wastes The solid matter generated by the component reaction is strongly cooled to 160°C in the lower part of the plasma reactor, and then discharged from the bottom material outlet into the material storage tank. The reaction formula of the above process is as follows:

[0044]

Embodiment 3

[0046] The organic waste containing fluorene enters the feed pipe through the raw material pump, is heated by the steam jacket to 89°C, and reaches the distributor after being mixed with the additive at the end of the feed pipe; the additive is methanol, and the molar ratio of the additive to the organic waste is 1 :1;

[0047] The temperature in the plasma reaction chamber is controlled at 7650°C. The fluorene in the organic waste breaks bonds and combines to form benzene, toluene and carbon monoxide, and completes partial plasmaization. The solid matter generated by the reaction of benzene, toluene and other components of the organic waste passes through the plasma reactor. After the lower part is cooled down to 150°C, it is discharged from the bottom material outlet to the material storage tank. The reaction formula of the above process is as follows:

Abstract

The invention relates to an ultra-low-temperature plasma organic waste recycling method and device. Organic waste enters a feeding tube through a raw material pump, is heated by a steam jacket, is mixed with an additive, is uniformly distributed via a distributor, and then enters a plasma reactor; after passing through plasma arcs which are generated by a plasma generator connecting coil and a cathode head on the upper part of the plasma reactor, the organic waste enters a plasma cavity and is subjected to plasma generation reaction; and the temperature in the plasma reaction cavity is controlled to be 749-782 DEG C, matter parts in the organic waste are subjected to bond breaking and are combined into two or more than two new matters to finish part of plasma generation, and the new matters are strongly cooled down by the lower part of the plasma reactor until the temperature is reduced to be below 160 DEG C, and then are discharged into a material storage tank via a bottom material outlet. By the ultra-low-temperature plasma organic waste recycling method and device, resource recycling is realized, moreover, energy consumed in a reaction process is greatly reduced, the additional value of by-products is greatly increased, and waste materials are changed into things of value.

Description

technical field [0001] The invention relates to the technical field of recycling of organic matter, in particular to an ultra-low temperature plasma organic waste recycling method and device for realizing partial plasmaization of organic waste. Background technique [0002] Energy issues and environmental issues are two hot issues in the world today. With the development of my country's social economy, the continuous acceleration of urbanization and the improvement of people's material life, on the one hand, the demand for disposable energy continues to grow. On the other hand, the amount of industrial waste and municipal solid waste (MSW) is also increasing rapidly, resulting in a huge waste of resources. With the increasingly widespread application of various heat treatment technologies in the treatment of environmental pollutants and the higher requirements for treatment efficiency of many difficult or special pollutants, the conventional heat treatment technology has gra...
