Abstract
The utility model relates to a liquid distributor for gas-liquid mass transfer equipment and provides a liquid distributor. The liquid distributor comprises a main pipe (1) and a branch pipe (2), wherein the branch pipe (2) is communicated with the main pipe (1). The liquid distributor is characterized in that the liquid distributor also comprises a spiral nozzle (3), and the spiral nozzle (3) is communicated with the branch pipe (2). The liquid distributor can disperse a liquid into fine liquid drops by dispersing the liquid by the spiral nozzle, increases the surface area of gas-liquid mass transfer, and greatly improves the distribution uniformity of the liquid, thereby improving the mass transfer efficiency of large-scale gas-liquid mass transfer or washing equipment.
Description
Technical field
The utility model relates to a kind of liquid distribution trough, belongs to the liquid distribution device field of chemical industry equipment.
Background technology
Gas-liquid mass transfer (contact) equipment, as absorption column of gas and scrubbing tower, whether being evenly distributed of absorption liquid or cleaning solution directly influences the effect that absorbs or wash.
At present, conventional gas, liquid mass transfer apparatus as absorption tower in the chemical industry and rectifying column, mostly adopt packed tower and plate column, and its liquid distribution trough generally adopts slot type, slotted disc type or tubular structure.But, in some special application scenarios, in the application such as the waste gas purification processing, liquid medium contains a large amount of solid fine graineds usually, be called paste liquid, adopt packed tower and plate column to occur phenomenon of blocking easily, need to adopt the spray tower of liquid medium high atomisation.Especially, in the boiler flue gas desulfurization tower of electric power and environmental protection industry (epi) widespread usage, atomisation tower is top-priority, and the diameter of desulfurizing tower is very big, and maximum can reach 16m, generally speaking all about 10m.But, for atomisation tower, especially large-scale atomisation tower, the effect of traditional liquid distribution trough is very poor, causes or increases tower height, or increase fluid flow, has both increased investment and has also increased energy consumption.
Therefore, provide a kind of novel, be specially adapted to contain the slurries system of solid, also be applicable to liquid distribution trough in large-scale gas-liquid mass transfer and the washing facility, can reduce investment and energy consumption, have crucial meaning.
Summary of the invention
The purpose of this utility model provides the liquid distribution trough in a kind of gas-liquid mass transfer (contact) equipment, to overcome the defective that prior art exists, satisfies industrial department, especially the needs of electric power and environment-protecting industrial.
Liquid distribution trough in the said gas-liquid mass transfer (contact) equipment of the utility model comprises the liquid releasing parts, and preferred spiral nozzle formula releasing parts also can comprise liquid delivery member and/or the liquid sub-unit that looses.
Liquid distribution trough of the present utility model is preferably the person in charge that comprises as liquid delivery member, as the loose arm of sub-unit and of liquid as the synthesis of the spiral nozzle of liquid releasing parts, said arm is connected with the person in charge, and said spiral nozzle is connected with arm.
The utility model is operation like this:
Absorption liquid enters arm by being responsible for, and by said spiral nozzle ejection, is disperseed by the spiral of nozzle then, forms tiny atomized drop, contacts with gas again, carries out the gas-liquid mass transfer operation.
Liquid distribution trough in the gas-liquid mass transfer (contact) equipment of the present utility model, by spiral nozzle, dispersing liquid can be tiny droplet with liquid dispersion, improves the gas-liquid mass transfer surface area greatly, improves the distributing homogeneity of absorption liquid, thereby improves gas-liquid mass transfer efficient.
