Description
Technical field
The utility model relates to a kind of dehydration device of methane, belongs to purification treatment technology field.
Background technology
Biogas must, through purifying, make the quality of biogas reach standard-required as a kind of energy before use.One of them just comprises the dehydration of biogas the purification of biogas.Biogas during from anaerobic ferment devices output, carries a large amount of moisture, and particularly, when middle temperature or thermophilic fermentation, biogas has higher humidity.When the biogas of higher levels of humidity flows in pipeline, due to temperature, the variation dew point of pressure reduces, water vapor condensation has increased biogas mobile resistance in pipeline, and the existence of water vapour has also reduced the calorific value of biogas, therefore need the water of condensation in biogas to remove, at present, conventional biogas dewatering is gravity method dehydration, cold partition method, solvent absorption and solid-state physics water suction method, gravity method dehydration removes the part water vapour in biogas with biogas gas-water separator, this biogas gas-water separator is mainly the horizontal filter screen of installation and vertically filter screen respectively up and down in tower, impel the water vapour in biogas Fen Li with biogas, but this device can not be collected water of condensation simply and easily, need the extra water collector equipment that increases, increased cost, cold partition method is to utilize pressure energy to change to cause temperature variation, makes the water vapour method that condensation is got off from gas phase, and this kind of device need pressurize or step-down processing, complicated and power consumption, solvent absorption is to utilize dehydrated solvent to absorb water vapour as calcium chloride, lithium chloride and glycols, and the possibility that this method is brought other impurity in having to biogas when absorbing water vapour will regularly replace dehydrated solvent simultaneously, solid-state physics water suction method is adsorbed under the effect of solid surface power and produces, sorbent material can not be regenerated after existing and dewatering and be needed the problem regularly replacing, complicated operation simultaneously cost is high, therefore research and develop simple, the energy-conservation and dehydration device of methane thoroughly that dewaters of a kind of equipment, is necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of dehydration device of methane, this device comprises main body 2, water leg 3, column spinner 4, web plate 6, filter screen 8, in the upper end of main body 2, be provided with inlet mouth 1, on the inwall of main body 2, be provided with a circle filter screen 8, the bottom of filter screen 8 is tapered, below filter screen 8, be provided with a circle water leg 3, water leg 3 bottoms are provided with water outlet 7, in the inside of main body 2, be provided with web plate 6, web plate 6 is positioned at below water leg 3, at the top of main body 2, column spinner 4 is housed, on column spinner 4, be provided with countervane 9, the bottom of main body 2 is provided with air outlet 5, the bottom of main body 2 is taper.
Column spinner 4 described in the utility model is connected with motor, and motor is connected with power supply.
The utility model sprinkled with siccative, processes for absorbing a small amount of water vapor that rear biogas contains on web plate 6.
Use procedure of the present utility model is: open motor, driven by motor column spinner 4 high speed rotating, then biogas is entered with tangential way from inlet pipe 1 with certain pressure, biogas is rotated under centrifugal action, powerful centrifugal force gets rid of the little water droplet in biogas to take off, and gather on filter screen 8, water droplet flows to the inwall of main body 2 downwards along filter screen 8, then along inwall, flow in water leg 3, then water is discharged by water outlet 7, when biogas rotation reaches cylindrical shell 2 bottom, through the siccative 4 on filter plate 6, further dehydration, finally dried biogas is discharged by air outlet 5.
Principle of work of the present utility model: because biogas is different from the density of little water droplet, biogas and little water droplet are mixed while flowing, the centrifugal force that little water droplet is subject to is greater than biogas, so liquid has the tendency of centrifugation, liquid is attached to the effect due to gravity on filter screen 8 and pools together downwards, and filter screen 8 has played the effect collecting with water of condensation.
The beneficial effects of the utility model: this device utilizes gas-liquid centrifugation principle, by column spinner and filter structure, make the water of condensation taking off from biogas flow into water leg downwards along cylinder inboard wall, be convenient to collect, the design of siccative web plate simultaneously can make biogas dehydration more thorough.
