Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining this practicality
Novel, it is not intended to limit scope of the present utility model.
Embodiment one: as it is shown in figure 1, the biogas recirculation desulphurization system of the present embodiment includes that the first desulfurizing tower 1 and second takes off
Sulfur tower 2, the lower end sidewall of above-mentioned first desulfurizing tower 1 and the second desulfurizing tower 2 is equipped with air inlet, and its top is equipped with gives vent to anger
Mouthful, the air inlet of above-mentioned first desulfurizing tower 1 gas outlet by above-mentioned second desulfurizing tower 2 of pipeline communication, above-mentioned first desulfurizing tower 1
Gas outlet by the air inlet of above-mentioned second desulfurizing tower 2 of pipeline communication, in above-mentioned first desulfurizing tower 1 and the second desulfurizing tower 2 point
It is not filled with desulfurizing agent.
Also including biogas air inlet supervisor 3, the air inlet of above-mentioned first desulfurizing tower 1 and the second desulfurizing tower 2 passes through pipeline respectively
Connect and be respectively equipped with electromagnetic valve on 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 passes through pipeline respectively
Connect above-mentioned biogas to give vent to anger 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 above-mentioned
It is respectively equipped with electromagnetic valve on the pipeline of the air inlet that the gas outlet of the first desulfurizing tower 1 connects above-mentioned second desulfurizing tower 2.
Gas concentration detection it is respectively equipped with at the gas outlet of above-mentioned first desulfurizing tower 1 and the gas outlet of the second desulfurizing tower 2
Device 5.
During use, when being used alone the first desulfurizing tower 1, close biogas air inlet supervisor 3 and the second desulfurizing tower 2 air inlet
Electromagnetic valve on pipeline between Kou, simultaneously closes off pipeline between the air inlet of the first desulfurizing tower 1 and the gas outlet of the second desulfurizing tower 2
On electromagnetic valve, and close the electromagnetic valve at the first desulfurizing tower 1 gas outlet, biogas is responsible for 3 communication conduits by biogas air inlet and is entered
First desulfurizing tower 1 is internal, reacts with desulfurizing agent therein, after question response certain time length, opens the first desulfurization 1 gas outlet
The electromagnetic valve at place, the biogas after desulfurization is entered biogas by pipeline and gives vent to anger supervisor 4, and afterwards, output is to follow-up package system.
After the first desulfurizing tower 1 is used alone certain time length, its interior desulfurizing agent active ingredient is gradually lowered, and can make to lead to
The biogas desulfurization entering it interior is insufficient, and is detected that it includes sulphur concentration by the gas concentration detector 5 of its gas outlet, works as inspection
Measure sulfur content in the biogas at gas outlet higher time, close its gas outlet and electromagnetism that biogas is given vent to anger between supervisor 4 on pipeline
Valve, and the electromagnetic valve opened between the air inlet of its gas outlet and the second desulfurizing tower 2 on pipeline so that gone out by the first desulfurizing tower 1
QI KOU biogas out carries out secondary desulfuration in importing the second desulfurizing tower 2, and carries out sulfur content inspection in the second desulfurizing tower 2 gas outlet
Survey, after detecting that sulfur content is up to standard in biogas, open the second desulfurizing tower 2 gas outlet and biogas is given vent to anger between supervisor 4 on pipeline
Electromagnetic valve, 4 is expelled to follow-up package system by biogas by the biogas supervisor 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 it is effective
Composition is down to minimum, closes pipeline solenoid between the first desulfurizing tower 1 air inlet and biogas air inlet supervisor 3 afterwards, and successively
Close the electromagnetic valve on pipeline between the first desulfurizing tower 1 gas outlet and the second desulfurizing tower 2 air inlet, stop the first desulfurizing tower 1
Use, and its interior desulfurizing agent is replaced.
Example two in real time: being used alone the second desulfurizing tower 2 and biogas is carried out desulfurization process, it is away from same embodiment 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, this mistake
Cheng Zhong, closes the electromagnetic valve on pipeline between the first desulfurizing tower 1 gas outlet and the second desulfurizing tower 2 air inlet, and it is de-to close first
Electromagnetic valve on pipeline between sulfur tower 1 air inlet and the second desulfurizing tower 2 gas outlet, makes the biogas being passed through in biogas air inlet supervisor 3
Carry out desulfurization process in being directed respectively into the first desulfurizing tower 1 and the second desulfurizing tower 2 after shunting respectively, pending after, respectively by both
Gas outlet converge to biogas by pipeline and give vent to anger in supervisor 4, concentrate afterwards to discharge and import follow-up package system.
When carrying out in biogas desulfurization processing procedure in the first desulfurizing tower 1 or the second desulfurizing tower 2, the moisture that biogas is contained within
Can be deposited in desulfurizing agent, and gradually ooze and drop down onto bottom tower body, therefore in above-mentioned first desulfurizing tower 1 and the bottom of the second desulfurizing tower 2
It is respectively communicated with and is provided with drain pipe 6, and respectively water check valve is set on drain pipe 6, it is simple to the deposit moisture in cleaning tower body in time,
Ensure being normally carried out of desulfurization work.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
