Exhaust gas absorbing device

Abstract

The invention discloses an exhaust gas absorbing device. An exhaust gas treatment device comprises a shell and a centrifugal fan, wherein two ends of the shell are open to form an air flue, absorbingliquid used for absorbing exhaust gas is contained in the air flue, the centrifugal fan is connected with the shell, and communicates with an air inlet, a liquid lifting part is arranged in the air flue, the liquid lifting part comprises a connection part and liquid containing parts which are connected with one another separately, and the connection part is rotatably connected with the shell, androtates relative to the shell when driven by air on one side of the air inlet, so that the liquid containing parts conduct reciprocating motion between the air flue and the absorbing liquid. Comparedwith the prior art, the exhaust gas treatment device has the advantages that through reaction of the absorbing liquid and harmful substances in the air, not only can an effect of purifying the air beachieved, but also power used for making the liquid lifting part throw the absorbing liquid into the air flue comes from the air which flows in the air inlet, therefore, a special power device is omitted, and the production cost and the running cost of the exhaust gas treatment device are saved.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a waste gas treatment device. Background technique [0002] Erlenmeyer flask is a common glass instrument, generally made of hard glass, brittle and fragile. The appearance is flat-bottomed and conical, and the longitudinal section is triangular in shape. The bottom is wide and the top is narrow. There is a cylindrical neck above the neck. There are several scales on the body of the bottle to indicate the capacity of the contents. The flat-bottomed conical structure of the Erlenmeyer flask is relatively stable, and it is generally not easy to dump. [0003] Due to the fragile nature of the Erlenmeyer flask, it is often necessary to use an exhaust gas absorption device in the experiment to prevent it from being damaged by falling. At present, laboratories often need to use different specifications of the Erlenmeyer flask, but the exhaust gas absorption...

Problems solved by technology

[0003] Due to the fragile nature of the Erlenmeyer flask, it is often necessary to use an exhaust gas absorption device in the experiment to prevent it from being damaged by falling. At present, laboratories often need to use different specifications of the Erlenmeyer flask, but the exhaust gas absorption device is often fixed-caliber , which requires a variety of exhaust gas absorption devices to adapt to different sizes of Erlenmeyer flasks, which not only increases the cost of the experiment, but also easily causes confusion when used, which is very inconvenient
