Problems solved by technology

The disadvantage of this fixing method is that the positioning accuracy of the bolt holes on the side wall of the gas riser is relatively high, which is not simple enough in actual production, and the installation height inside the tower is often very limited, so it is difficult for the installer to tighten the bolts in the vertical direction. difficulty

Embodiment 1

[0019] see Figure 1-Figure 4 As shown, the technical solution adopted in this specific embodiment is: an improved gas-lifting structure of a trough-disk gas-liquid distributor, which includes a gas-lifting cylinder 1, bolts 2, nuts 3, connecting angle steel 4, connecting plate 5, retaining The liquid plate 6 is characterized in that: the lift cylinder 1 is a straight tube that penetrates up and down, the liquid baffle plate 6 is arranged above the lift cylinder 1 and completely covers the lift port of the lift cylinder 1, and the connecting plate The upper end of 5 is vertically welded to the bottom surface of the liquid baffle plate 6, the lower end of the connecting plate 5 has a horizontal bending edge, and the two ends of the connecting angle steel 4 are spot welded to the inner side wall of the upper end of the lifting cylinder 1, One side of the connecting angle steel 4 is on the same horizontal plane as the upper end surface of the air lifting port of the lifting cylin...

Embodiment 2

[0025] The difference between this embodiment and embodiment 1 is:

[0026] The cross section of the liquid baffle 6 is V-shaped.

[0027] The liquid baffle 6 is 100 mm away from the upper end surface of the air cylinder 1 .

[0028] The working principle of the present invention: the connecting angle steel 4 is positioned and spot welded according to the actual situation at the construction site, which can reduce the requirements for the positioning accuracy of the bolt holes and facilitate production and processing; because the installation height inside the tower is often very limited, the connecting plate 5 and the bolt holes connecting the angle steel 4 are all arranged on the horizontal side, which is beneficial to the operation of the installer; meanwhile, this detachable air-lifting structure also greatly facilitates the maintenance of the equipment in the middle and late stages.

[0029] After adopting the above technical solution, the beneficial effects of the prese...

Abstract

The invention discloses a gas lifting structure of an improved groove disc type gas-liquid distributor, and relates to the technical field of chemical industry packing tower internal member equipment.The gas lifting structure comprises a gas lifting cylinder, a bolt, a nut, connecting angle steel, a connecting plate and a liquid baffle, wherein the gas lifting cylinder is a straight cylinder which is through up and down, the liquid baffle is arranged above the gas lifting cylinder and completely covers the gas lifting port of the gas lifting cylinder, the upper end of the connecting plate isvertically welded with the bottom surface of the liquid baffle, a horizontal bent edge is arranged at the lower end of the connecting plate, two ends of the connecting angle steel are spot-welded withthe inner side wall of the upper end of the gas lifting cylinder so as to make one edge of the connecting angle steel and the upper end surface of the gas lifting port of the gas lifting cylinder bepositioned on the same horizontal plane, and the connecting plate and the connecting angle steel are matched through the bolt, the nut and a bolt hole and are in threaded connection and fixation. Compared with the prior art, the gas lifting structure of the invention has the following characteristics that the fixing mode of the liquid baffle is improved, so that the gas lifting structure has the advantages of being simple and convenient to install, low in manufacturing precision requirement, beneficial to middle and later maintenance of equipment and the like.

Description

technical field [0001] The invention relates to the technical field of internal parts equipment of chemical packing towers, in particular to an improved gas-lifting structure of a groove-disk gas-liquid distributor. Background technique [0002] In oil refining, ethylene, petrochemical, fine chemical, food, pharmaceutical and environmental protection industries, towers are important unit equipment. Packed towers are widely used in tower design due to their high separation efficiency, high operating flexibility, small pressure drop and large production capacity. [0003] The gas-liquid distributor is one of the most important internal components in the packed tower, and its performance directly affects the product index of the packed tower. An ideal gas-liquid distributor should have the characteristics of good gas-liquid distribution effect, large operating flexibility, small pressure drop, easy production, easy maintenance, and low cost. [0004] Slot plate gas-liquid dis...
