Description
Technical Field
The utility model relates to a chemical tower equipment among the chemical industry field, more specifically say, relate to a direction bar-type float valve and overall arrangement structure on the column plate thereof with slope direction mouth
Background
The plate-type tower is a kind of stepped contact mass transfer equipment for gas-liquid or liquid-liquid system, and is formed from cylindrical tower body and several tower plates which are horizontally placed in the tower according to a certain distance. The method is widely applied to rectification and absorption, and some types (such as sieve plate towers) are also used for extraction, and can also be used as a reactor for a gas-liquid phase reaction process. During operation (taking a gas-liquid system as an example), liquid flows through the tower plates of each layer from top to bottom in sequence under the action of gravity and is discharged from the bottom of the tower; the gas is driven by pressure difference to pass through each layer of tower plate from bottom to top and is discharged from the top of the tower. A liquid layer with a certain depth is kept on each tower plate, and gas is dispersed into the liquid layer through the tower plates to carry out interphase contact mass transfer.
The overflow weir is a structure for overflowing liquid on the tower plate, has the functions of maintaining a liquid layer on the plate and enabling the liquid to overflow uniformly, and can be divided into an outlet weir and an inlet weir. Except some cases, most of the overflow weirs are provided with arched weirs, and the length of the weir can be 0.6 to 0.8 times of the diameter of the tower. The outlet weir is generally a flat weir, and when the flow rate is small, a tooth-shaped weir can be adopted, and the height of the weir depends on different plate types and liquid load. The inlet weir is primarily intended to reduce the impact of liquid rushing out at the inlet on the flow of tray liquid.
In the rectangular area between the two weirs, the liquid flows at a constant speed, which is called as an active area or a constant flow speed area; in the arcuate region on either side of the weir where there is no direct scouring, the liquid is stationary or slowly circulating, referred to as a liquid stagnant region. The liquid in the arch area has slow flow velocity, easy back mixing and low mass transfer efficiency.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model provides a direction bar-type float valve and overall arrangement structure on the column plate with slope direction mouth adopts the direction mouth that the slope set up, and the guide is gaseous to erodeing the bow-shaped district, can improve the liquid delay condition in the bow-shaped district, and technical scheme is as follows.

Thus, the gas can be guided to obliquely blow into the arch area, and the flow speed of the liquid in the arch area is accelerated.
According to direction bar-type float valve with slope direction mouth and overall arrangement structure on the column plate thereof, its characterized in that: the guide strip-shaped float valve with inclined guide opening is arranged in the arch-shaped area 2 of the tower plate 1.
According to direction bar-type float valve with slope direction mouth and overall arrangement structure on the column plate thereof, its characterized in that: a guide strip-shaped float valve with inclined guide opening is arranged at the front part of the arch area, and the gas guide opening 5 faces the top of the arch area.
According to direction bar-type float valve with slope direction mouth and overall arrangement structure on the column plate thereof, its characterized in that: a guide strip-shaped float valve with an inclined guide port is arranged at the rear part of the arch area, and the gas guide port 5 faces the outlet weir.
According to direction bar-type float valve with slope direction mouth and overall arrangement structure on the column plate thereof, its characterized in that: the included angle alpha gradually decreases from large along with the position change from the middle part close to the inlet weir to the middle part of the arched area, the alpha angle at the middle part of the arched area is the minimum value, and the included angle alpha gradually increases from small along with the position change from the middle part of the arched area to the position close to the outlet weir.
According to direction bar-type float valve with slope direction mouth and overall arrangement structure on the column plate thereof, its characterized in that: the guide strip-shaped floating valves with inclined guide openings are symmetrically arranged in the arch-shaped areas on two sides of the tower plate 1.
