Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining this
Invention, is not intended to limit the scope of the present invention.
Embodiment one: as it is shown in figure 1, the biogas recirculation desulphurization system of the present embodiment includes the first desulfurizing tower
1 and second desulfurizing tower 2, the lower end sidewall of above-mentioned first desulfurizing tower 1 and the second desulfurizing tower 2 is equipped with
Air inlet, its top is equipped with gas outlet, and the air inlet of above-mentioned first desulfurizing tower 1 is by pipeline communication
Stating the gas outlet of the second desulfurizing tower 2, the gas outlet of above-mentioned first desulfurizing tower 1 is by pipeline communication above-mentioned the
The air inlet of two desulfurizing towers 2, is separately filled with desulfurization in above-mentioned first desulfurizing tower 1 and the second desulfurizing tower 2
Agent.
Also including biogas air inlet supervisor 3, the air inlet of above-mentioned first desulfurizing tower 1 and the second desulfurizing tower 2 divides
Tong Guo not be respectively equipped with electromagnetic valve on pipeline communication above-mentioned biogas air inlet supervisor 3, and two pipelines of correspondence.
Also including that biogas is given vent to anger supervisor 4, the gas outlet of above-mentioned first desulfurizing tower 1 and the second desulfurizing tower 2 is divided
Do not given vent to anger by the above-mentioned biogas of pipeline communication and be respectively equipped with electromagnetic valve on supervisor 4, and two pipelines of correspondence.
The air inlet of above-mentioned first desulfurizing tower 1 connects the pipeline of the gas outlet of above-mentioned second desulfurizing tower 2
And on the pipeline of the gas outlet of above-mentioned first desulfurizing tower 1 air inlet that connects above-mentioned second desulfurizing tower 2 point
It is not provided with electromagnetic valve.
It is respectively equipped with gas at the gas outlet of above-mentioned first desulfurizing tower 1 and the gas outlet of the second desulfurizing tower 2
Concentration detector 5.
During use, when being used alone the first desulfurizing tower 1, close biogas air inlet supervisor 3 and second
Electromagnetic valve on pipeline between desulfurizing tower 2 air inlet, simultaneously closes off the air inlet and of the first desulfurizing tower 1
Electromagnetic valve on pipeline between the gas outlet of two desulfurizing towers 2, and close at the first desulfurizing tower 1 gas outlet
Electromagnetic valve, biogas is responsible for 3 communication conduits by biogas air inlet and is entered the first desulfurizing tower 1 inside, with therein
Desulfurizing agent reacts, and after question response certain time length, opens the electromagnetic valve at the first desulfurization 1 gas outlet,
Biogas after desulfurization is entered biogas by pipeline and gives vent to anger supervisor 4, and afterwards, output is to follow-up package system i.e.
Can.
After the first desulfurizing tower 1 is used alone certain time length, its interior desulfurizing agent active ingredient is gradually lowered,
The biogas desulfurization being passed through it interior can be made insufficient, and examined by the gas concentration detector 5 of its gas outlet
Measure it and include sulphur concentration, when detecting that in the biogas at gas outlet, sulfur content is higher, close it and give vent to anger
The electromagnetic valve that mouth and biogas are given vent to anger between supervisor 4 on pipeline, and open its gas outlet and the second desulfurizing tower 2
Air inlet between electromagnetic valve on pipeline so that imported by the first desulfurizing tower 1 gas outlet biogas out
Carry out secondary desulfuration in second desulfurizing tower 2, and carry out sulfur content detection in the second desulfurizing tower 2 gas outlet,
After detecting that sulfur content is up to standard in biogas, open the second desulfurizing tower 2 gas outlet and biogas give vent to anger supervisor 4 it
Between electromagnetic valve on pipeline, biogas is expelled to follow-up package system by the biogas supervisor 4 that gives vent to anger.
In said process, it is continually fed into biogas in the first desulfurizing tower 1, desulfurizing agent in it is made full use of,
Until its effective ingredient is down to minimum, closes the first desulfurizing tower 1 air inlet afterwards and be responsible for 3 with biogas air inlet
Between pipeline solenoid, and close the first desulfurizing tower 1 gas outlet and the second desulfurizing tower 2 air inlet successively
Between electromagnetic valve on pipeline, stop the use of the first desulfurizing tower 1, and its interior desulfurizing agent carried out more
Change.
Example two in real time: be used alone the second desulfurizing tower 2 and biogas is carried out desulfurization process, it is away from implementing
Example one.
Embodiment three: simultaneously use the first desulfurizing tower 1 and the second desulfurizing tower 2 that biogas is carried out high-efficiency desulfurization
Process, during this, close pipeline between the first desulfurizing tower 1 gas outlet and the second desulfurizing tower 2 air inlet
On electromagnetic valve, and close between the first desulfurizing tower 1 air inlet and the second desulfurizing tower 2 gas outlet on pipeline
Electromagnetic valve, be directed respectively into the first desulfurizing tower 1 He after making to be passed through the biogas shunting in biogas air inlet supervisor 3
Carry out desulfurization process in second desulfurizing tower 2 respectively, pending after, respectively by both gas outlets by pipe
Road converges to biogas and gives vent to anger in supervisor 4, concentrates afterwards and discharges the package system that importing is follow-up.
When carrying out in biogas desulfurization processing procedure, in biogas in the first desulfurizing tower 1 or the second desulfurizing tower 2
The moisture contained can be deposited in desulfurizing agent, and gradually ooze and drop down onto bottom tower body, therefore in above-mentioned first desulfurization
The bottom of tower 1 and the second desulfurizing tower 2 is respectively communicated with and is provided with drain pipe 6, and sets on drain pipe 6 respectively
Put water check valve, it is simple to the deposit moisture in cleaning tower body in time, it is ensured that being normally carried out of desulfurization work.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all in the present invention
Spirit and principle within, any modification, equivalent substitution and improvement etc. made, should be included in this
Within bright protection domain.
