Specific embodiment
Below with reference to embodiment, the utility model is described in further detail.
The utility model proposes a kind of equipment applied to biogas long distance transportation, including sequentially connected biological desulphurization
Tower, dry desulfurizing tower, dust removal filter, roots blower, dehydration device and compressor, biogas are successively located by above-mentioned each device
Deposit is into medium pressure tank vehicle after reason；The dehydration device includes air-cooled unit 4, evaporator 2, condensation water tank 3 and dewatering box 1,
The condensation water tank is connect by outlet pipe with dewatering box.
The utility model proposes a kind of equipment applied to biogas long distance transportation, the equipment make the biogas produced according to
Secondary desulfurization, dedusting, compression, dehydration, recompression are stored and are realized by medium pressure tank vehicle so that biogas reaches using standard
Long-distance transportation.
Firstly, the equipment includes that sweetening process, the biogas of generation first pass through biological desulphurization tower and carries out once desulfurization, life twice
Object desulfurizing tower can avoid being passed through security risk caused by air to anaerobic jar, while low cost, high efficiency desulfurization, favorably
In anaerobic digestor stable operation, dry desulfurizing tower can ensure that the hydrogen sulfide content of terminal biogas lower than 20mg/Nm3, solve life
The unstable drawback of object desulfurization meets requirement of the industrial user to biogas makings.It is combined, is made with dry desulfurization by biological desulphurization
The existing biological desulphurization of this equipment handles feature large-minded, that overall cost is low, and have that dry desulfurization stability is good, it is with high accuracy
Feature.
The utility model may include 1-3 dry desulfurizing tower, when the quantity of dry desulfurizing tower is 2-3, each dry method
Connecting pipe between desulfurizing tower and biological desulphurization tower is equipped with valve, so, can be convenient for the replacement of dry desulfurizing tower.
Refrigerant is sent into evaporator by the air-cooled unit of the utility model dehydration device, is carried out to the biogas entered in dewatering box
Cooling and dehydration, condensed water enter condensation water tank through outlet pipe, and the biogas that import high-temperature is 35 DEG C drops in this process
As low as 10 DEG C or less.The evaporator of the present embodiment is shell and tube water-biogas heat exchanger.Refrigerant is between air-cooled unit and evaporator
Circulation, air-cooled unit and evaporator, refrigerant circulation process are the prior art, and details are not described herein.
The dewatering box of the utility model includes intermediate rectangular cavity being arranged in, and be symmetricly set on the company at rectangular cavity both ends
Chamber is connect, the end of side connecting cavity is equipped with air inlet pipe, and the end of other side connecting cavity is equipped with escape pipe, and the evaporator is located at square
Shape is intracavitary.Wherein, air inlet pipe and escape pipe are round tube, and the outside of entry/exit tracheae adds flange, is easily installed；The present embodiment
In rectangular cavity be square chamber, stay certain space before and after evaporator, to increase cooling effect, evaporator up and down with dehydration
The gap that 5 centimetres or so are kept between the rectangular cavity of case, facilitates installation.Gap between evaporator and dewatering box uses soft material
Material filling is so that dewatering box is divided into front and rear part, and since evaporator itself has the gap, biogas passes through between evaporator gap, this
Sample can guarantee that the biogas entered is discharged after cooling and dewatering.Dehydration box space is larger to be conducive to biogas cooling and dewatering, meanwhile, because
In roots blower operational process, the biogas of outlet end is pressed with pulse (air pressure regularly fluctuation up and down), and dewatering box can be used as slow

The low adverse effect to follow-up equipment.
The utility model uses the two stages of compression of Roots blower and biogas compressor, and impurity is to Roots blower in biogas
It influences small, is hardly damaged, i.e., the biogas of normal pressure is first improved into pressure to 0.1MPa with Roots blower, enter back into Marsh gas compression
Machine, by biogas compressor compressed biogas to 4MPa.This mode alleviates the load of biogas compressor, reduces biogas compressor
Failure rate.
Gas is unloaded to when using gas end in medium pressure tank vehicle, due to unloading aspiration heat, is caused to unload the reduction of tracheae channel temp, is easy to produce
Raw ice is stifled, and gas velocity degree is unloaded in reduction, unloads port in medium pressure tank vehicle and installs automatic constant-temperature heating tape additional, can solve the problems, such as that ice is stifled.In addition, through
Treated that biogas can be deposited by aerating column into medium pressure tank vehicle for overcompression machine, and medium pressure tank vehicle fills, long distance transportation to biogas
With gas end.Automatic constant-temperature heating tape is the prior art, is not showed that in attached drawing.
