Description
Technical field
This utility model belongs to desulfurization by dry method field, is specifically related to a kind of biogas dry method desulfuration system.
Background technology
Yunnan Province is the big province of growing vegetables, and vegetable can produce discarded fruit and vegerable in plantation, sales section, only has little portion at present
Divide discarded fruit and vegerable to be used as feedstuff, remaining utilization the most not yet in effect, be arbitrarily discarded in village, field, bring serious environmental problem.
In order to solve numerous environmental problems that local discarded fruit and vegerable bring, discarded fruit and vegerable are turned waste into wealth, people using discarded fruit and vegerable as
Raw materials for production, prepare biogas by dry anaerobic fermentation, biogas by bioanalysis desulfurization, decarburization, be dried, pressurization after as car
Supply market with compressed natural gas (or CNG), comprehensively solve local environment and pollute and industrial gas problem, and periphery is saved
City's agricultural waste utilization, energy development will play good demonstration and guiding function.During wherein biogas desulfurization is this technique
One the most key link, desulfurization processes bad, environment can be caused secondary pollution, be unfavorable for environmental protection.The most conventional place
Reason method has wet desulphurization and biological desulphurization.What wet desulphurization used that sodium carbonate, ammonia and alkanolamine solution etc. absorb hydrogen sulfide is
Chemical absorption method；With cold methanol absorb hydrogen sulfide for Physical Absorption method；Employing alkaline solution is absorbent, and adds oxygen carrier
For desulfurizing agent, absorb hydrogen sulfide.Biological desulphurization is by being imported by a certain amount of air in the biogas containing hydrogen sulfide, utilizes raw
The process of thing reaction biological removal hydrogen sulfide.All there are long flow path, installations and facilities bulky complex, operation fiber crops in both sulfur methods
Tired, and be only suitable for processing the higher flue gas of sulfur content or combustion gas.But for using discarded fruit and vegerable as anaerobic fermentation raw material, send out
For the biogas that after ferment, the sulfur content in biogas is relatively low, there will be desulfuration efficiency according to wet method and biological two kinds of sulfur methods low
Under, desulfurized effect is poor, purifies halfway problem.Therefore, developing a kind of flow process short, device structure is simple, and work continuous-stable,
Desulfuration efficiency is high, and the biogas dry method desulfuration system that gas purification degree is high is desirability.
Utility model content
The purpose of this utility model is to provide a kind of flow process short, and device structure is simple, and work continuous-stable, desulfuration efficiency
Height, the biogas dry method desulfuration system that gas purification degree is high.
The purpose of this utility model is achieved in that and includes saturator, desulfurizing tower A, desulfurizing tower B and decontaminating separator,
The low side of saturator is provided with biogas input pipe, the high-end escape pipe that is provided with, and is provided with between biogas input pipe and escape pipe
Bypass line, the escape pipe of saturator air inlet pipe with desulfurizing tower A and desulfurizing tower B low side respectively is connected, desulfurizing tower A and desulfurizing tower
The high-end exhaustor that is provided with of B, the low side of decontaminating separator is provided with purification gas inlet tube, high-end is provided with clean gas outlet
Pipe, is connected with purification gas inlet tube after the two exhaustor parallel connections of desulfurizing tower A and desulfurizing tower B, the exhaustor of desulfurizing tower A and desulfurization again

Connect, purify gas inlet tube and be connected with clean gas outlet pipe by the 4th bypass pipe.
The exhaustor of desulfurizing tower A is connected with the air inlet pipe of desulfurizing tower B by this utility model by the second bypass pipe, desulfurizing tower
Exhaustor the 3rd bypass pipe of B passes through to be connected with the air inlet pipe of desulfurizing tower A.Two towers are conducive in process of production after so connecting
Phase double replacement, it is ensured that the seriality of desulfurization process.This is because the desulfurizing agent in desulfurizing tower is after the regeneration of 3～5 times, desulfurization
Agent chemism is substantially reduced, and needs the desulfurizing agent more renewed.After so arranging when changing the desulfurizing agent of arbitrary tower in two towers,
All ensure that what desulfurization worked is normally carried out continuously, will not influence each other.It addition, this utility model arranges saturated in two tower front ends
Tower, can make biogas be introduced into after saturator reaches water saturation and enter back into desulfurizing tower, so be conducive to accelerating desulphurization reaction, improves
Desulfuration efficiency.Meanwhile, this utility model also arranges decontaminating separator at the afterbody of two desulfurizing towers, so can remove clean further
The desulfurization dust carried in activating QI body, the purity making purification gas is higher.Therefore, this utility model is that a kind of flow process is short, equipment
Simple in construction, work continuous-stable, and desulfuration efficiency is high, and the biogas dry method desulfuration system that gas purification degree is high is worth of widely use.
