Description
The technical field is as follows:
the utility model relates to the field of chemical equipment, in particular to a tail gas absorption system used in sulfolene desulfurization.
Background art:
an absorption tower is a device that performs an absorption operation. The liquid-gas phase contact state can be divided into three types. The first type is a plate tower, a bubbling absorption tower and a stirring bubbling absorption tower, wherein gas is dispersed in a liquid phase in a bubble form; the second type is an ejector, a venturi, a spray tower in which liquid is dispersed in a gas phase in the form of droplets; the third type is a packed absorption column and a falling film absorption column in which liquid contacts with a gas phase in a film-like motion. The gas-liquid two-phase flow mode in the tower can be countercurrent or cocurrent. Usually, a countercurrent operation is adopted, the absorbent flows from top to bottom in the tower top, and contacts with the gas flowing from bottom to top, the liquid absorbed with the absorbent is discharged from the bottom of the tower, and the purified gas is discharged from the top of the tower.
The contact area of absorbed gas and absorbed liquid in an absorption tower used in the existing sulfolene desulfurization is small, the absorption effect is influenced, and the environment is polluted by sulfur dioxide emission.
The utility model content is as follows:
the utility model aims to solve the technical problem of providing a tail gas absorption system for sulfolene desulfurization, which has large contact area between absorbed gas and liquid and good absorption effect.
The above object is achieved by: the absorption tower comprises two absorption towers with the same structure, wherein the two absorption towers are a first absorption tower and a second absorption tower;
the first absorption tower comprises a tower body, a tail gas outlet is formed in the top of the tower body, an alkali liquor outlet is formed in the bottom of the tower body, a sulfur dioxide inlet is formed in the tower body above the alkali liquor outlet, a filler is arranged in the tower body above the sulfur dioxide inlet, and the filler is spherical; a spraying plate is arranged in the tower body above the spherical filler, the spraying plate comprises a box body, a plurality of spraying holes are formed in the lower surface and the side surface of the box body, an alkali liquor inlet pipeline is arranged on the tower body above the spraying plate, the inner end of the alkali liquor inlet pipeline extends into the box body of the spraying plate, and the box body of the spraying plate is fixed on the alkali liquor inlet pipeline; the alkali liquor enters the spraying plate from the alkali liquor inlet pipeline.
The other end of the pipeline connected with the sulfur dioxide inlet of the first absorption tower and the sulfur dioxide inlet of the second absorption tower is connected with a sulfur dioxide conveying pipeline, two valves are arranged on the sulfur dioxide conveying pipeline, and the joint of the other end of the pipeline connected with the sulfur dioxide inlet of the second absorption tower and the sulfur dioxide conveying pipeline is positioned between the two valves on the sulfur dioxide conveying pipeline; the tail gas outlets at the tops of the two absorption towers are connected with a tail gas discharge pipeline, and the other end of the sulfur dioxide conveying pipeline is connected with the tail gas discharge pipeline.
The utility model has the advantages that: because the absorption tower adopts the spray plate and the spherical filler, the contact area of the absorbed gas and the absorption liquid is larger, and the sulfur dioxide and the alkali liquor are more fully contacted, thereby completing the neutralization reaction, improving the absorption effect and reducing the pollution to the environment. The two absorption towers can be controlled by valves to be used in parallel or in series, and the use is flexible and convenient.
