Novel harmful gas absorbing device for experiment

Abstract

The invention discloses a novel harmful gas absorbing device for an experiment. The novel harmful gas absorbing device comprises a filling part 1, a connection pipe 2 and an adapter 3. The filling part 1 is connected to the connection pipe 2. The adapter 3 is installed on the filling part 1. Multiple grading purification is used so that toxic gas is fully purified, a manual butterfly valve for emergency closing is used so that when an absorbing medium loses efficacy, a pipe is peremptorily closed and poison gas leakage-caused personal danger is prevented, multiple interlayers are used and a separator wall with a netty hollow structure is arranged between each two interlayers so that a material filling pipe can be repeatedly filled with different materials and thus a space is saved, efficiency is improved and a cost is reduced, the adapter is provided with outside threads and outside thread edge is provided with a rubber seal ring so that the screw thread device convenient for dismounting, mounting and replacement is convenient for replacement at any time, and the rubber seal is used so that poison gas is sealed and leakage is avoided.

Description

technical field [0001] The invention belongs to the field of chemical experiments, and relates to a novel harmful gas absorption device for experiments. Background technique [0002] During chemical reactions, especially organic synthesis reactions, some toxic and harmful gases are often produced or used, such as H2S, HCl, NO, NO2, SO2, etc., as well as organic waste gases such as alcohols and ethers. These pollutants are not only harmful to the human body, but some are also carcinogens. If they are directly discharged into the atmosphere without treatment, they will cause harm to the health of the experimenters and the surrounding environment. Therefore, one-stage or multi-stage gas absorption devices are often used to absorb harmful gases. At present, the improvement of the shortcomings of the traditional gas absorption device involves the type of packing of the absorption device, the height of the tower, the gas distributor and the use of equipment to reduce the emission...

AI Technical Summary

Problems solved by technology

At present, the improvement of the shortcomings of the traditional gas absorption device involves the type of packing of the absorption device, the height of the tower, the gas distributor and the use of equipment to reduce the emission of gas, but there are few modifications to the structure of the absorption tower

[0003] In view of the inconvenience and safety hazards brought by traditional devices to experiments, a new harmful gas absorption device for laboratory experiments is specially designed.
