Abstract
The utility model discloses a sulfonated tail gas absorbing device. The sulfonated tail gas absorbing device is characterized by comprising an absorbing tank for absorption liquid, a Venturi tube and a buffer, wherein the Venturi tube is connected with the absorbing tank and provided with a tail gas inlet, and the buffer is connected with the absorbing tank and provided with a tail gas outlet. A centrifugal pump sucking the absorption liquid into the Venturi tube is arranged between the Venturi tube and the absorbing tank. The sulfonated tail gas absorbing device in the above structure is simple in structure, high in efficiency and long in service life.
Description
Technical field
The utility model relates to the chemical products production field, is specifically related to the sulfonated tail gas absorption plant.
Background technology
Water reducer is a kind of chemical products, is take crude naphthalene as primary raw material, forms the water reducer product of liquid naphthalene system through sulfonating reaction, condensation reaction and neutralization reaction.The tail gas that contains naphthalene that produces in the water reducer production process can to environment, be unsuitable for direct discharging.
Present sulfonated tail gas absorption plant, topology layout is loaded down with trivial details, and it is short that Venturi tube is corroded service life.
The utility model content
