When the invention works, gas enters through the steam inlet 101 at the lower side part of the tower body 104, ammonia water enters from the first liquid inlet 105 at the upper part, the ammonia water flows to the tower plate assembly 200 and forms a thin layer on the surface through the overflow weir 202, then water vapor upwards contacts with the guide plate 206 through the tower plate body 201 with the sieve holes, so that ascending gas flow is horizontally sprayed out without mutual impact with liquid drops, the spraying direction of the gas flow is not consistent with the direction of the ascending gas flow in the whole tower, because the liquid drops are easily separated from the gas flow by inertia effect, the local speed is changed into the empty tower speed, the entrainment quantity is smaller, the production capacity is improved, the gas and the liquid are continuously dispersed, polymerized and the surface is updated by maintaining a proper liquid layer on the tower plate body 201, the material transfer is promoted, the guide plates 206 are arranged into a plurality of rows and are staggered, so that the gas flows of two adjacent rows of guide plates 206 are continuously sprayed and mutually restrained, the continuous acceleration phenomenon of gas is eliminated, so that the gas and the liquid are well contacted, and the middle adapter piece 300 is arranged among the plurality of tower plate assemblies 200, so that the liquid after mass transfer uniformly enters the next tower plate assembly 200, taking the first embodiment as an example: the bellmouth 301 is positioned at the bottom of the tray assembly 200 and is used for receiving liquid discharged by the downcomer 204, the downcomer 204 in this embodiment is an annular structure, the annular structure is hermetically connected with the outside of the tray body 201 to form the overflow weir 202, the top surface of the overflow weir 202 is provided with an overflow hole 203, the overflow hole 203 is communicated with the downcomer 204, the shape of a water outlet at the bottom of the downcomer 204 can be circular, triangular, long-strip or rectangular, the liquid is discharged from the bottom of the downcomer 204 and then is contacted with the first inclined surface 303 at the bottom of the bellmouth 301, enters the first liquid leaking platform 304 along with the surface of the first inclined surface 303, is discharged through the through hole part on the first liquid leaking platform 304 and enters the tray assembly 200 below, then the redundant liquid reaches the second liquid leaking platform 306 through the second inclined surface 305 and is discharged through the through hole part on the second liquid leaking platform 306 and enters the tray assembly 200 below, the excessive liquid reaches the third liquid leaking platform 308 through the third inclined surface 307, is discharged through the through hole part on the third liquid leaking platform 308 and enters the lower tower plate assembly 200, and the excessive liquid is discharged through the liquid outlet 302 through the fourth inclined surface 309, so that uniform blanking can be realized.
According to the invention, the tower body 104 is internally provided with the plurality of tower plate assemblies 200 with the inclined-hole tower plates, and the middle adapter 300 is arranged between two adjacent tower plate assemblies 200, so that liquid between two adjacent tower plate assemblies 200 is uniformly converted, the efficiency of forming a liquid layer by the overflow weir 202 on the lower tower plate body 201 is better improved, and the phenomenon of upward dry blowing of air flow is reduced.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
