Described roots blower 5 is commercially available prod (prior art), such as the trilobal cross Roots blower that Nantong Heng Rong pump Co., Ltd., Factory produces; Described air-cooled radiator 6 is commercially available prod (prior art), the air-cooled tube wing-type radiator that Equipment Limited as energy-conservation in Jiaozhuo supportan produces; Described pressure regulator valve 8 is commercially available prod (prior art), pressure regulation spectrum 1 ~ 25kPa, fluctuates less than 1mbar, such as the gas pressure regulating valve that Hebei Fu Ruida gas pressure regulator, governor company limited produces; Described spark arrester 10 is commercially available prod (prior art), such as the flame arrester for pipe that Shanghai Shi Hua petrochemical equipment company limited produces.
When this utility model uses, increasing a control chamber, wherein critical piece is controller 11, can adopt the S7-200SMART that Siemens produces. Controller, by analyzing the signal of each sensor acquisition, controls the running status of each equipment.
Owing to rear end equipment is more sensitive to the pressure oscillation of gas, steady for strengthening transfer of gas, pressure regulator valve is installed in this utility model exit.
Increasing a condensation water collecting device 13, during use, water level displaying tube communicates with tank body, and the height of water level inside can be shown by water level displaying tube, can check the water level height of tank interior when workman patrols and examines in outside. Tank body is provided with water level alarm 5, and described water level alarm is the ball float water level alarm of the model ZR801F series that commercially available prod (prior art) produces as opened up auspicious science and technology (Zhengzhou) finite instrument company. Equipped with ball float on water level alarm, fluctuate according to SEA LEVEL VARIATION. When water inlet pipe inflow is relatively larger, water level in tank body rises, ball float rise therewith triggering " high water level " report to the police (this alert locations need to be determined according to tank body height), issue a signal to controller 11, automatically water pump is started by controller, starting to externally drained, the pump mouth connecting water pipe of water pump 7 is to the bottom of tank body, and discharge outlet connecting line is to user appointed place. Along with the draining of water pump 7, water level decreasing in tank, ball float triggers " middle water level " and reports to the police, and it is out of service that controller controls water pump. Along with the condensation water collected accumulates gradually, in tank body, water level begins to ramp up, then enter the next one draw water, draining, stopping circulation. Due to other situations; water level continues to decline (such as tank body leakage, high temperature evaporation etc.); ball float is caused to continue descending; then trigger " low water level " and report to the police (this alert locations need to calculate according to actual suction pressure); controller sends stopping signal; after artificial investigation fault, just putting into operation, otherwise extraneous air easily enters in gas handling system. The draining warning system of water pump 7, water level displaying tube 2 and 5 groups of cost apparatus of water level alarm.
When actually used, the location point that the height of tank body, the length of negative pressure water pipe, the degree of depth added water first, " high, normal, basic " are reported to the police, the pressure size being required for condensing water according to equipment negative pressure calculates, it is then determined that each size, makes each equipment further according to dimensioned.
Described negative pressure water pipe extend into tank base, is subsequently adding in tank body a certain amount of water. This part water, under atmospheric pressure effect, can enter into negative pressure water pipe, and for preventing aqueous reflux from entering in the dehydration equipment of gas treatment, the vertical length of negative pressure water pipe must calculate according to peak suction. This part water also acts as sealing function simultaneously, it is prevented that extraneous air is entered in gas handling system by negative pressure water pipe. Negative pressure water pipe is too short, amount of water is very few first, capital has influence on the sealing property of drainage by suction, by adopting this equipment, some thus can be made to have the condensing plant of vacuum requirement, successfully can discharge condensing water, avoid extraneous air to enter into internal system simultaneously.
Described malleation water pipe should not stretch in tank body long, but floating ball hydrophobic water valve must be installed in front end. Otherwise biogas under positive pressure, can be put in air by positive pressure water bank of tubes along with condensing water. When biogas runs up to finite concentration, it may occur that the dangerous situations such as blast. And being also a kind of energy waste, rear end equipment operates by biogas after all.
Condensation water collecting device achieves pipeline and seals, and collects multichannel negative pressure simultaneously and condenses water Auto-drainage with malleation, keeps the sealing of whole system.
When this utility model runs, the biogas produced after fermentation, first pass through air inlet duct and enter in devulcanizer 1, air inlet duct is provided with first sensor, the original state of detection biogas, feeds back to control controller.Desulfurizing agent in devulcanizer 1 reacts with the corrosive gas sulfide in biogas, and sulfide content is reduced to below 100ppm. Biogas after desulfurization enters into the first filter and carries out preliminary remove impurity and dehydration, removes bigger foreign material and aqueous water in biogas, and aqueous water is discharged to condensation water collecting device 13 from bottom. Biogas enters back into cooling driers 3, and biogas is cooled so that it is in contained saturated steam condense into drop, be discharged to condensation water collecting device by pipeline. Cold dry after biogas enter back into gas-liquid separator 4, through inner cyclone air flue, tiny mist state drop and aqueous water are separated, after collecting, row is to condensation water collecting device. Through this dehydration several times dehumidifying, it is ensured that biogas humidity, about 70%, by the second sensor detected gas moisture content on pipeline, feeds back to controller and is adjusted. Biogas after dehydration is carried out supercharging output by roots blower 5, and blower fan adopts VFC, and by the second sensor detected gas pressure and flow, controller is adjusted according to feedback signal. After supercharging, biogas temperature rises, air-cooled radiator 6 lower the temperature, make outlet temperature less than 40 DEG C. Last biogas, through the second filter, removes fine particle further. For stabilization of export pressure, spy increases a pressure maintaining valve 8, makes outlet pressure pulsations less than 5%. A spark arrester 10 is installed in exit, can block the detonation caused by rear end equipment. The aqueous water discharged, in pipe influx to condensation water collecting device, shows situation, regular draining according to liquid level.
Compared with prior art, this utility model simple in construction, safe and reliable, effectively purify the biogas of small-sized fermentation engineering, solve macro-corrosion gas, foreign material and aqueous water in fermentation methane, and narrow-minded, the problems such as air pressure fluctuation is big. And easy for installation, it is the innovation of gas purification in fermentation engineering, has good Social and economic benef@.
