Definitions
- the present invention relates to a reduced-pressure heat treatment apparatus, a reduced-pressure heat treatment facility, a reduced-pressure heat treatment method, and a method for producing activated carbon of environmentally harmful residual organic chemical substances. More specifically, reduced-pressure heating of environmentally harmful residual organic chemicals that are harmful to the environment and the human body, in particular, PCBs, dioxins, waste medicines, waste agricultural chemicals, harmful proteins, etc.
- the present invention relates to a treatment apparatus, a reduced pressure heat treatment facility, a reduced pressure heat treatment method, and a tongue charcoal method.
- the treatment object containing the environmentally harmful residual organic chemical substance is defined as the soil or environment that has absorbed the environmentally harmful residual organic chemical substance, which is composed of only liquids and materials containing the environmentally harmful residual organic chemical substance. It is a concept that includes wood, paper, plastic, containers storing environmentally harmful residual organic chemicals, containers for condensers and transformers, and stabilizers such as fluorescent lights, etc., impregnated with toxic residual organic chemicals.
- the processed material does not contain environmentally harmful residual aneriological substances, it is harmful to the human body and difficult to dispose of, such as powder such as meat-and-bone meal and livestock-related substances. Also includes industrial waste. Background art
- Harmful environmentally harmful biological substances such as PCBs and dioxins are not easily generated in the natural environment. For this reason, harmful environmentally harmful residual organic chemicals are decomposed by incineration at a high temperature of 1000 ° C or higher, or heated with a dechlorinating agent such as an organometallic compound. It is processed by converting it to harmless substances by dechlorination. .
- dioxin is generated when the treatment temperature is lowered, and untreated harmful environmentally harmful organic chemicals may remain in the ash gas generated by the leg treatment. There is a problem that there is.
- treatment by the dechlorination reaction can prevent the generation of dioxin.However, environmentally harmful residual organic chemicals adhering to containers and harmful chemicals impregnated in solids such as wood, paper, and plastic are not affected. However, since it cannot be sufficiently reacted with the dechlorinating agent as it is, it cannot be treated.
- Substrates 1 and 2 contain solid substances such as polyvinyl chloride and organic chemicals such as waste oil in a evacuated container, and are heated to 300 to 400 ° C. Is decomposed.
- the organic chemical substance is heated in a state of low oxygen concentration, it is possible to prevent the generation of dioxin in the heating / heating process.
- Substrate 1 since the pressure is up to 300-400 ° C and the inside of the container does not heat up, substances that can be decomposed at relatively low temperatures, such as polyvinyl chloride, can be treated, but PCBs, dioxins, waste chemicals, Substances that cannot be used at high temperatures of 650 ° C or higher, such as waste pesticides and harmful proteins, have a problem that they cannot be treated with calo heat.
- the treated substances such as waste oil are transferred from the container in which they are stored to the heat of the caro ⁇ , and are treated.
- the drums, transformers, condensers, etc., in which waste oil and the like are stored, are treated. Even if these containers are contaminated, they cannot be cleaned.
- the present invention can efficiently and thermally decompose environmentally harmful residual organic chemicals impregnated in liquids and solids containing environmentally harmful residual organic chemicals in a short period of time. Dioxin generation can be suppressed, and organic chemicals in exhaust gas generated during power ⁇ heat treatment can be reliably decomposed and the container containing the organic chemicals can be purified.
- the treated material after the treatment of environmentally harmful residual organic chemicals can be used for effective cultivation (J can be used, and it is easy to carry the environmentally harmful residual organic chemicals into the vacuum heat treatment equipment. It is an object of the present invention to provide a reduced pressure heat treatment apparatus, a reduced pressure heat treatment equipment, a reduced pressure heat treatment method, and a method for producing carbonaceous carbon of a substance having environmental harmful residual properties.
- the reduced-pressure heating apparatus for environmentally harmful residual organic chemical substances according to the first invention is a processing apparatus for subjecting an object to be treated containing environmentally harmful residual organic chemical substances to caloric heat treatment, wherein the processing apparatus is provided.
- a heating vessel having an airtight heating chamber for accommodating the object to be processed, vacuum means for vacuuming the working port heat chamber, and raising the temperature of the heating chamber to 650 ° C. or more. And heating means for maintaining the heating chamber at 650 ° C. or higher.
- the reduced-pressure heating apparatus for environmentally harmful residual substance according to the second invention is characterized in that, in the first invention, the means of self-reflection heating is one night.
- a pressure-reduction heating apparatus for environmentally harmful residual organic substances wherein the heater is disposed in a carothermal chamber of the heating container.
- the apparatus for heat-reducing environmentally harmful organic chemical substances under reduced pressure is the device according to the second invention, wherein the heating vessel is provided so as to surround an inner cylinder forming the heating chamber and an outer surface of the inner cylinder.
- the inner cylinder is made of a high heat-resistant material, and a plurality of the heaters are arranged on the outer surface of the inner cylinder between the inner cylinder and the outer cylinder.
