A laboratory furnace for heavy metal hyperaccumulation plants

Abstract

The invention discloses a heavy metal hyperaccumulation plant combustion furnace used for a laboratory. The heavy metal hyperaccumulation plant combustion furnace used for the laboratory comprises a gas inlet system, a combustion furnace body and a tail gas treating system; the combustion furnace body comprises a shell, a furnace door, an incineration area, a gas inlet pipeline and a gas outlet pipeline; a micropore sintering filter disk is arranged in the gas outlet pipeline; the joint of the gas outlet pipeline and the incineration area is provided with a groove; a drawer used for containing incineration samples is placed in the incineration area; a fly ash collecting box is arranged in the groove; the gas inlet system comprises a fuel gas bottle and a pipeline; one end of the pipeline is connected with the fuel gas bottle, and the other end of the pipeline is connected with the gas inlet pipeline; the tail gas treating system comprises an electric dust remover and an absorbing tower; and one end of the electric dust remover is connected with the gas outlet pipeline, and the other end of the electric dust remover is connected with the absorbing tower. According to the heavy metal hyperaccumulation plant combustion furnace used for the laboratory, in the research trial of the laboratory, heavy metal hyperaccumulation plants are placed in the drawer, combustion is more sufficient, taking and placing of the heavy metal hyperaccumulation plants and collecting of fly ash are facilitated, waste gas generated after incineration is treated, and the atmospheric environment is protected.

Description

technical field [0001] The invention belongs to the technical field of combustion furnaces, and in particular relates to a laboratory-used heavy metal super-enrichment plant combustion furnace. Background technique [0002] At present, with the development of industry and the increase in the types and quantities of agricultural chemicals, the pollution of heavy metals in my country's soil is becoming more and more serious, the degree of pollution is intensifying, and the area of ​​pollution is expanding year by year. Plants absorb heavy metals in the soil and transport them to the aboveground parts of the plants, and then harvest the mature heavy metal hyperaccumulator plants to remove heavy metals from the soil. The disposal of the harvested heavy metal hyperaccumulator plants is usually incineration In order to reduce the space volume of plant storage, it can concentrate the content of heavy metals. However, in the process of laboratory research and experiments on the incine...

[0002] At present, with the development of industry and the increase in the types and quantities of agricultural chemicals, the pollution of heavy metals in my country's soil is becoming more and more serious, the degree of pollution is intensifying, and the area of ​​pollution is expanding year by year. Plants absorb heavy metals in the soil and transport them to the aboveground parts of the plants, and then harvest the mature heavy metal hyperaccumulator plants to remove heavy metals from the soil. The disposal of the harvested heavy metal hyperaccumulator plants is usually incineration In order to reduce the space volume of plant storage, it can concentrate the content of heavy metals. However, in the process of laboratory research and experiments on the incineration treatment of heavy metal hyper-accumulated plants after harvest, there are often insufficient incineration and incineration. The final fly ash is not easy to collect and the waste gas will produce secondary environmental pollution after incineration
