Description

Spray cooling mechanism and contain preliminary knockout drum of carbon disulfide of this mechanism Technical Field The invention relates to the technical field of waste gas purification, in particular to a spray cooling mechanism and a carbon disulfide preliminary separation tower containing the same. Background In the industrial production and recovery process of carbon disulfide, the primary separation tower is one of core equipment, and the primary function of the primary separation tower is to pretreat mixed waste gas containing carbon disulfide, and transfer the carbon disulfide in the waste gas to a liquid phase in a spraying absorption or condensation mode to realize gas-liquid primary separation, so that a foundation is laid for a subsequent refining process, and meanwhile, the pollution of carbon disulfide emission to the environment is reduced, and the resource waste is reduced. In the prior art, the spray purification structure of the carbon disulfide preliminary separation tower generally adopts the traditional layout of a spray header and a packing layer, and the working flow is that the spray header is arranged at the upper part of the separation tower, and sprays liquid such as low-temperature absorption oil (wash oil) or cooling circulating water and the like into the separation tower, wherein the absorption oil absorbs carbon disulfide in waste gas by means of a similar compatibility principle, the cooling circulating water condenses carbon disulfide steam into liquid state by cooling, the packing layer is arranged under the spray header, structured packing or random packing is mostly adopted, mixed waste gas containing carbon disulfide rises from the lower part of the tower body, passes through the packing layer and contacts with liquid sprayed by the spray header on the surface of the packing, absorption and condensation of the carbon disulfide are realized through gas-liquid mass transfer, after preliminary separation is finished, purified waste gas is discharged from the top of the tower, and liquid phase containing the carbon disulfide is collected from the bottom of the tower and sent to subsequent procedures for further treatment. However, in practical application, the conventional spray purification device is limited by the limitation of structural design, and has various defects and disadvantages, such as that the liquid sprayed by the spray header is in a natural falling state and contacts with the waste gas mainly by means of gravity, the liquid falling speed is high, the residence time is short, a continuous liquid film is easily formed on the surface of the packing layer, a large amount of liquid flows along the wall surface or the liquid film of the packing layer, a wall flow short circuit phenomenon is formed, and the liquid cannot be fully contacted with the waste gas. Simultaneously, when waste gas passes the packing layer from bottom to top, receive the liquid film to block and easily appear air current drift, local dead zone for the two-phase area of contact of gas-liquid is limited, contact time is not enough, and gaseous carbon disulfide absorbs incompletely, finally leads to waste gas purification efficiency to be lower, is difficult to effectively satisfy the separation demand of carbon disulfide waste gas.
