The utility model has the advantages of reliable structure, simple fabrication, even gas distribution, small liquid backmixing, high tower plate efficiency strong processing capability, specially big operation flexibility, etc. The utility model can be extensively suitable for the gas liquid mss transfer operations of distillation, absorption and gas stripping, etc.
Description
The utility model relates to a kind of structure of core component-column plate of plate column.
As everyone knows, industrial, plate column has obtained using widely as gas-liquid two-phase mass transfer, heat-transfer equipment.Early seventies has been developed a kind of angle iron tower plate.Shortcomings such as the position of placing by angle steel can be divided into ∨ type angle iron tower plate and ∧ type angle iron tower plate, and that this class individual layer angle iron tower plate has is simple in structure, resistance drop is little and efficient advantages of higher relatively, carries under one's arms greatly but exist mist, and operating flexibility is little.Afterwards, occurred the float type angle iron tower plate again, although make moderate progress on operating flexibility, angle steel fluctuates and has brought complex structure, easy to wear coming off, and the mist big shortcoming of carrying under one's arms still exists, and is further improved.
The purpose of this utility model is to overcome the shortcoming of above-mentioned all kinds of angle iron tower plates, has designed a kind of combined type angle iron tower plate, has reliable in structure, make simply, distribution of gas is even, and operating flexibility is big, advantages such as pressure drop is little, thus the operating characteristics and the mass-transfer efficiency of angle steel plate column further improved.
Design of the present utility model is such:
1, combined type angle steel structure is set on column plate, the upper strata is a ∧ type angle steel.Lower floor is a ∨ type angle steel, the alternate cross lamination of two-layer angle steel is arranged, thereby make gas passage vertically become the gas passage that angle steel constituted of gas by cross lamination from bottom to top and be the W type by liquid level by common, gas imports from W type middle crest point slit (gas passage inlet), bifurcated flows out again, thereby has reduced gas kinetic energy component in vertical direction, reduces entrainment; Simultaneously, because the change of gas flow, mass transfer has been strengthened in the turbulent extent aggravation when making the gas-liquid contact.
2, on two arms of angle of upper strata ∧ type angle steel, have aperture, be intended to improve the uniform property of gas, gas-liquid two-phase is contacted more equably, further improve mass-transfer efficiency, also reduce the pressure drop of column plate simultaneously effectively, improve the operating flexibility of tower.
3, two-layer up and down angle steel all is orderly bar shaped arrangement, and the length direction of angle steel and the liquid flow path direction on the column plate are consistent, thereby have reduced the liquid dispersion on the column plate, help improving mass-transfer efficiency.
4, two-layer up and down angle steel adopts stationary structure, can overcome because movable structure brings shortcomings such as mechanical wear, makes simple and reliable for structure.
