Embodiment 1

[0035] combined with figure 2 , the spray cover 8 on the tray 12 of a column gas-liquid exchange system designed by the present invention is cylindrical, and the tray lift hole 10 is circular, and the center corresponds to the center of the spray cover. The swirl blades 11 are inclined at 25° to the horizontal tray, and are in the shape of a fan. 12 sets of swirl blades are installed in the air hole.

[0036] combined with image 3 , The collection plate 5 of the tower gas-liquid exchange system is in the shape of a dustpan as a whole, one end is fixed on the downcomer plate 2, the two sides are fixed on the tower wall 9, and the open end 14 is slightly bent downward and extends into the downcomer. The spray cover 8 passes through the collecting plate and is sealedly connected with the collecting plate.

[0037] combined with Figure 4 , The separator 7 of the tower gas-liquid exchange system is a cylindrical hollow cylinder, and the horizontal axis 15 passes through the ...

Abstract

The invention discloses a tower device gas-liquid exchange system. The system includes a swirling vane type riser hole, a spray cover, a downcomer plate, a collecting plate, a separator, and a separation plate; a swirl blade type riser hole is arranged on the tray, and the corresponding position of the riser hole is fixed by a support. There is a gap between the bottom of the spray cover and the tray, which forms the channel for the liquid on the tray to enter the spray cover; there are spray holes on the side wall of the spray cover, and a gas-liquid separation plate is arranged on the top; The liquid separator, the downcomer plate and the tower body constitute the downcomer, the collecting plate is fixed on the back of the downcomer outside the downcomer, the two ends of the tangent line perpendicular to the downcomer plate are fixed on the tower wall, and the other end bends downward Lower tray downcomer. The system of the invention can strengthen the gas-liquid contact and improve the gas-liquid mass transfer efficiency; moreover, the energy consumption level is low, the structure is simple, and the installation and maintenance are convenient.

Description

technical field [0001] The invention belongs to gas-liquid mass transfer and heat transfer equipment in the fields of petrochemical industry, environmental protection, etc., and specifically relates to a tower gas-liquid mass transfer and heat transfer technology, and more specifically relates to a tower gas-liquid exchange system. technical background [0002] Various mass transfer trays are commonly used in logistics separation technology in petrochemical and environmental protection industries. According to its structure, it can be divided into sieve tray, bubble cap tray, valve tray, swirl tray, three-dimensional tray and other types. These trays have their own advantages and disadvantages, such as: sieve tray The plate structure is simple and the processing gas volume is large, but the operation flexibility is small, especially when the load is low, liquid short circuit or plate leakage is easy to occur; bubble cap trays and valve trays have good operating flexibility, ...
