Description
Technical field
The utility model belongs to methane purification absorption tower technical field, is specifically related to a kind of packed absorber of purifying for biogas pressurization WATER-WASHING METHOD.
Background technology
The elution of biogas pressure (hydraulic) water is pure is the difference of utilizing methane and carbon dioxide solubility in water, under certain operation condition in absorption tower water by carbon dioxide absorption, then by desorb by the release of carbonate dioxide in water, lean solution is returned to absorption tower and is completed circulation.Generally there are two kinds of forms on absorption tower: the one, and plate column, the 2nd, conventional filler tower.Current domestic methane purification is still in the starting stage.Because biogas contains a certain amount of CO
2and H
2s gas easily produces corrosion to equipment in water-washing process, therefore adopt the packed absorber with corrosion-resistant filling, can improve the decay resistance of equipment.In addition, because biogas output is generally little, adopt packed tower can accomplish less tower diameter, and reduce tower height, improved the economy of equipment.In addition, packed tower is made simple compared with plate column.Comprehensive above-mentioned characteristic, in methane purification project, adopts packed tower to be better than plate column.The packed absorber use that still belongs to the first time in methane purification, be subject to the impact of biogas output and biogas characteristic, conventional filler tower is for methane purification fluctuation of service, operating pressure is difficult for ensureing, purity of product gas is difficult for reaching, and gas product is easily with liquid, in the situation that environment temperature is low, easily cause the faults such as gas product pipeline freezes after gas vent.
Utility model content
The utility model object is to provide a kind of packed absorber of purifying for biogas pressurization WATER-WASHING METHOD.
For achieving the above object, the utility model adopts following technical scheme:
An absorption tower of purifying for biogas pressurization WATER-WASHING METHOD, comprises tower body, and wherein, described tower body is vertical structure, and tower body comprises the retaining section that is positioned at the packing section of top and is positioned at below; Described packing section top is provided with gas vent, and gas vent below arranges one or more layers wire mesh demister; Described packing section top is provided with liquid-inlet, packing section bottom is provided with gas feed, liquid-inlet is positioned at the below of wire mesh demister, in tower body, between liquid-inlet and gas feed, be provided with one or more levels material distributor, material distributor below is provided with filler matching used with it, and this filler is fixed by the packing support that is arranged at tower body inwall; Retaining pars infrasegmentalis is provided with liquid outlet, and retaining section sidewall is provided with far transmission level meter.
Concrete, described packing section roof is also provided with teletransmission pressure gauge.The bottom of described tower body is provided with skirt.
Preferably, described gas feed is connected with inverted U-shaped bend pipe, and liquid flows backwards and enters gas piping when preventing that in tower, liquid level is too high.
In actual applications, the diameter of tower body packing section is less than retaining section diameter (retaining section diameter is about 1-1.2 times of packing section diameter); Packing section adopts cone to be connected with retaining section.
Between two stage material distributors, be provided with liquid header.
In the present invention, in tower body, gas vent below preferably arranges double-deck wire mesh demister, and between the two apart from 15 centimetres of left and right, wire mesh demister is all higher than the liquid-inlet on tower wall, for further purifying the gas of discharging.
The far transmission level meter that tower body sidewall arranges, carries out chain control with the control valve in liquid outlet pipeline, in order to ensure the 60-80% of liquid level in gas feed height in tower.The teletransmission pressure gauge that tower body sidewall arranges, carries out chain control with the control valve in gas vent pipeline, can monitor tower internal pressure, in order to ensure that tower internal pressure is not less than operating pressure.
Compared to the prior art, the beneficial effects of the utility model:
Adopt vertical filling-material structure, improved the decay resistance of equipment and the operating efficiency on absorption tower, gas product quality can reach national natural gas primary standard.Stability and the reliability of equipment operation have been improved by liquid level and pressure interlock setting; Double-deck wire mesh demister has thoroughly effectively solved product gas carrying liquid problem; Below retaining section reducing increases the continous-stable that has improved absorption liquid circulation, has reduced equipment tower height.
