Abstract
The invention discloses a washing tower, which comprises a tower body with a cavity. A gas inlet, a gas outlet, a liquid inlet and a liquid outlet are formed on the tower body; a filler layer used for making gases and the washing liquid closely contacted for performing mass transfer is arranged inside the tower body; and a space for a gas to rise is formed between the filler layer and the gas outlet in the tower body. When leaving the surface of the filler layer, a gas carries away some washing liquid droplets, but the liquid droplets will descend under action of gravity while the gas carrying the liquid droplets rises in the space, and thus, the gas is separated from the liquid droplets. In the device, the arrangement of the rising space removes the washing liquid impurity from the gas without adopting external operation or equipment, the washing tower is simple to operate, and the production cost is low.

Because the present invention has adopted above technical scheme, its advantage is: be useful on the space that supplied gas rises in tower body between packing layer and gas vent, when the gas band drop and risen in the space, drop can be realized separating of gas and drop because the gravity effect be walked downward.This section rising space is set, need not extra operation or equipment and just can realize removing the cleaning solution impurity of sneaking in the gas, simple to operate, it is low to produce input cost.
Description of drawings
Accompanying drawing 1 is a cutaway view of the present invention.
The specific embodiment
Further set forth concrete structure of the present invention below in conjunction with accompanying drawing.
A kind of scrubbing tower, comprise tower body 1 with inner chamber, offer gas inlet and outlet 2 and 3, cleaning solution import and export 4 and 5 on the tower body 1, be provided with in the tower body 1 and be used to make gas to contact the packing layer 6 that carries out mass transfer closely with the washing liquid phase, packing layer 6 comprises filler gripper shoe 9, place filler on the gripper shoe 9, be pressed in the hold-down grid 15 of filler top, and hold-down grid 15 is pushed down filler in case blown by ascending air.Mass-transfer efficiency when guaranteeing that gas and cleaning solution contact, the reverse setting of gas and cleaning solution, as shown in Figure 1, gas feed 2 is located at the bottom of tower body 1 sidewall, gas vent 3 is located on the tower body 1 on the roof, cleaning solution import 4 is located at the top of tower body 1 sidewall, and cleaning solution outlet 5 is located on tower body 1 diapire.In the present embodiment, filler adopts stainless steel wire stratum reticulare or porcelain circular layer, the gaseous mixture that gas obtains for methanol decomposition hydrogen manufacturing, composition comprises methyl alcohol, hydrogen, carbon monoxide, carbon dioxide etc., cleaning solution adopts deionized water, in fact, the material of filler, be washed other materials that gas, cleaning solution can adopt those skilled in the art to know, the scrubbing tower device among the present invention all can use.Gas enters the inner chamber of tower body 1 from import 2, rise, cleaning solution is sprayed onto the surface of filler through import 4, wetting filler, gas rises by the space of filler, because the methyl alcohol in the gas can be water-soluble, so gas is by behind the packing layer 6, and the methyl alcohol in the gas is absorbed by water, gas is when output, its composition mainly is a hydrogen, carbon monoxide, carbon dioxide, gas can be taken away the drop of cleaning solution when breaking away from packing layer 6 surperficial, in tower body 1, between packing layer 6 and gas vent 3, be useful on the space 7 that supplied gas rises, when the gas band drop and risen in space 7, drop can be realized separating of gas and drop because the gravity effect be walked downward.This section rising space 7 is set, need not extra operation or equipment and just can realize removing the cleaning solution impurity of sneaking in the gas, simple to operate, it is low to produce input cost.
In order to monitor clean result, near gas vent 3 places or gas vent 3, be equiped with thermometer 8 on the tower body 1.In Fig. 1, the thermometer 8 of temperature when being used to detect gas output is equipped with on the top of tower body 1 at close gas vent 3 places, temperature is generally in suitable scope, guarantee that deionized water fully washes out the methyl alcohol in the gas, if temperature is too high, methyl alcohol and deionized water evaporation sneak in the gas of output, and clean result can descend.Cleaning solution is after the surface of packing layer 6 absorbs methyl alcohol, because the effect of gravity, can fall, from cleaning solution outlet 5 outputs, be connected with water circulating pump and deionized water make-up system between cleaning solution outlet 5 and the import 4, because deionized water has loss certainly in washing process, therefore need carry out supply.When the measured temperature of thermometer 8 was too high, water circulating pump can be strengthened work, and more cleaning solution can pump in the tower body 1, strengthens the absorption to methyl alcohol, reduces evaporation.
Disposal ability for reinforcer, what the filler of filling should be evenly good in the scrubbing tower is wetted, thereby cleaning solution import 4 is provided with liquid distribution trough, and cleaning solution is sprayed onto on the filler by liquid distribution trough, further, in order to improve the mass-transfer efficiency of gas and cleaning solution, gas feed 2 is provided with gas distributor, and gas enters the inner chamber of tower body 1 after distributing, rise, contact with cleaning solution the surperficial of filler full and uniformly, carry out mass transfer.Also be provided with the cooling device 13 that is used for refrigerating gas on the tower body 1, gas enters packing layer 6 more earlier through cooling, and helps the absorption of methyl alcohol.In Fig. 1, tower body 1 comprises tower body 11, following tower body 12, is provided with packing layer 6 in the last tower body 11, and cooling device is arranged on the following tower body 12, the top that gas goes out 3, cleaning solution import 4 is opened in packing layer 6 on the tower body 11, gas feed 2, cleaning solution outlet 5 are opened in down the bottom of tower body 12.The inner chamber of following tower body 12 has two-layer, comprise mutual disconnected atrium 17 and exocoel 18, gas inlet and outlet 2 and 3, cleaning solution are imported and exported 4 and 5 and all only are connected with atrium 17, and cooling device comprises exocoel 18, is located at down on the tower body 12 and the cooling fluid that is connected with exocoel 18 import and export.When gas when distributor is input to down in the inner chamber of tower body 12, logical cooling fluid in exocoel 18, cooling fluid and gas converting heat, gas is lowered the temperature, after the methyl alcohol cooling in the gas may condensation take place a part, condensing droplet is because gravity effect meeting whereabouts, be absorbed after mixing with the washing liquid phase, after another part methyl alcohol enters packing layer 6 in the gas, being washed liquid on the surface of filler fully absorbs, by cooling device 13 is set, can guarantee that the methyl alcohol in the gas is absorbed substantially fully, improve the absorptivity of methyl alcohol.
Cleaning solution is after absorbing methyl alcohol, from cleaning solution outlet 5 outputs, when washing process carries out continuously, can accumulate cleaning solution in the inner chamber of tower body 1, too many in order to prevent the cleaning solution accumulation, and too slow from exporting 5 outputs, thus the mass transfer of gas and cleaning solution influence, be used to measure cleaning solution liquid level liquid level gauge 14 just so be provided with at tower body 1.
