Description

Technical Field

[0001] The invention relates to the technical field of biogas biological desulfurization equipment, and in particular to an integrated biogas biological desulfurization treatment device and a treatment method. Background Art

[0002] Biogas biological desulfurization refers to biogas biocatalytic desulfurization, which is a biological metabolic process that uses desulfurization microorganisms to catalyze hydrogen sulfide in biogas and selectively convert hydrogen sulfide into sulfuric acid or elemental sulfur by controlling the oxygen concentration. Biogas biological desulfurization technology is widely used in biogas, landfill gas, natural gas, water gas and other industrial gas desulfurization processes. The main biological desulfurization used in biogas can be roughly divided into two categories, one is integrated biological desulfurization, and the other is separated biological desulfurization. Among them, integrated biological desulfurization has low operating costs and is widely used in power generation and combustion projects of biogas with low concentration of hydrogen sulfide (below 10,000ppm).

[0003] During the long-term desulfurization of biogas, desulfurization microorganisms will grow biofilms on the biological filler. In severe cases, the biofilm can reach a thickness of several millimeters.

[0012] Furthermore, the integrated biogas biological desulfurization treatment device has the following steps: S1: When in use, the water pump is started, and the water pump will extract the liquid containing desulfurization microorganisms in the bottom of the bioreactor and input it into the transmission water tank. The liquid will drive several transmission blades to rotate, and the transmission blades will drive the rotating shaft to rotate, and the rotating shaft will drive the rectangular lifting slide rod to rotate, and the rectangular lifting slide rod will drive the circular sleeve to rotate, and the circular sleeve will drive the hollow rectangular slide rod to rotate. The rotation of the hollow rectangular slide rod will generate centrifugal force, and the centrifugal force will swing the hollow rectangular slider away from the circular sleeve. At the same time, the hollow rectangular slider rotates, and the hollow rectangular slider will drive several round rods to move. The round rods will rotate synchronously under the rotation of the hollow rectangular slider, and the round rods will also rotate at the same time under the action of the cleaning brush. During the rotation of the cleaning brush, the biofilm generated in the air of the filter plate will be punctured and cleaned out; S2: In the process of the hollow rectangular slider moving away from the circular sleeve, the hollow rectangular slider will rotate and move close to the annular mounting block under the action of rotation. When the hollow rectangular slider contacts the trapezoidal limit plate on the annular mounting block, the trapezoidal limit plate will push the hollow rectangular slider to move in the direction close to the circular sleeve under the action of its inclined surface. After the hollow rectangular slider passes the circular fixing rod, the hollow rectangular slider will move in the direction away from the circular sleeve under the action of centrifugal force. At this time, the hollow rectangular slider forms a reciprocating motion. In the process of the reciprocating motion of the hollow rectangular slider, the transmission gear on the hollow rectangular slider will drive the round rod to rotate under the action of the transmission tooth plate, and the round rod will drive the cleaning brush to rotate. The cleaning brush will rotate during the cleaning process; S3: The liquid passing through the transmission water tank will be discharged from the infusion pipe into the spray hood, and the liquid will be discharged from the spray hood and sprayed onto the filter plate. The liquid will spread from the holes on the filter plate to multiple filter plates. After the biogas enters the bioreactor, it will pass through multiple filter plates. Several filter plates containing liquid will increase the contact area with the biogas, thereby improving the desulfurization effect. During the rotation of the circular sleeve, several cleaning plates will be driven to rotate. The cleaning plates will clean the impurities remaining on the surface of the filter plate. During the rotation of the cleaning plates, the impurities will be thrown into the annular collection box and collected through the annular collection box to avoid impurities remaining on the surface of the filter plate and cause blockage. During the rotation of the cleaning plates, the liquid may also be thrown into the annular collection box. The liquid entering the annular collection box will enter the collection hood from the filter hole, and then flow from the collection pipe at the bottom of the collection hood to the bottom of the bioreactor for reuse; S4: During the rotation of the circular fixed rod, the circular lifting plate will also be driven to rotate, and the circular lifting plate will drive the trapezoidal block 1 to rotate. When the trapezoidal block 1 rotates, it will contact the trapezoidal block 2. When the trapezoidal block 1 contacts the trapezoidal block 2, the trapezoidal block 1 will rise. At this time, the trapezoidal block 1 drives the circular lifting plate to rise, and the corresponding circular sleeve will also rise with the circular lifting plate. The circular sleeve will drive the filter plate to rise, and the filter plate will drive the annular vibration plate to rise. After the trapezoidal block 1 leaves the trapezoidal block 2, the trapezoidal block 1 will drop, and the annular vibration plate will also drop. In this process, the filter plate forms an up and down reciprocating motion. In this process, several filter plates will vibrate. In the process of vibration, the fine impurities and broken biofilms remaining in the filter plate holes will be shaken out, and they will be cleaned into the annular collection box with the help of the cleaning plate to avoid clogging of the filter plate.

[0013] The present invention has the following beneficial effects: (1) The present invention provides an integrated biogas biological desulfurization treatment device. When in use, the water pump is started, and the water pump will extract the liquid containing desulfurization microorganisms in the bottom of the bioreactor and input it into the transmission water tank.

The rotation of the hollow rectangular slide rod will generate centrifugal force, and the centrifugal force will swing the hollow rectangular slide rod away from the circular sleeve. At the same time, the hollow rectangular slide rod rotates, and the hollow rectangular slide rod will drive a plurality of round rods to move. The round rods will rotate synchronously under the rotation of the hollow rectangular slide rod, and the round rods will also rotate at the same time under the action of the cleaning brush. During the rotation of the cleaning brush, the biofilm generated in the air of the filter plate will be punctured and cleaned out; (2) The present invention provides an integrated biogas biodesulfurization treatment device. In the process of the hollow rectangular slider moving away from the circular sleeve, the hollow rectangular slider will rotate and move close to the annular mounting block under the action of rotation. When the hollow rectangular slider contacts the trapezoidal limit plate on the annular mounting block, the trapezoidal limit plate will push the hollow rectangular slider to move in the direction close to the circular sleeve under the action of its inclined surface. After the hollow rectangular slider passes the circular fixed rod, the hollow rectangular slider will move in the direction away from the circular sleeve under the action of centrifugal force. At this time, the hollow rectangular slider forms a reciprocating motion. In the process of the reciprocating motion of the hollow rectangular slider, the transmission gear on the hollow rectangular slider will drive the round rod to rotate under the action of the transmission gear plate, and the round rod will drive the cleaning brush to rotate. The cleaning brush will rotate during the cleaning process. The rotation will disperse the bristles on the cleaning brush to further improve the effect of cleaning the biofilm. (3) The present invention provides an integrated biogas biological desulfurization treatment device. The liquid passing through the transmission water tank will be discharged from the infusion pipe into the spray hood. The liquid will be discharged from the spray hood and sprayed onto the filter plate. The liquid will spread from the holes on the filter plate to multiple filter plates. After the biogas enters the bioreactor, it will pass through multiple filter plates. The multiple filter plates containing liquid will increase the contact area with the biogas, thereby improving the desulfurization effect. During the rotation of the circular sleeve, it will drive multiple cleaning plates to rotate. The cleaning plates will clean the impurities remaining on the surface of the filter plates. During the rotation of the cleaning plates, the impurities will be thrown into the annular collection box and collected by the annular collection box to avoid clogging caused by impurities remaining on the surface of the filter plates. During the rotation of the cleaning plates, the liquid may also be thrown into the annular collection box. The liquid entering the annular collection box will enter the collection hood from the filter hole, and then flow from the collection pipe at the bottom of the collection hood to the bottom of the bioreactor for reuse, thereby reducing the waste of desulfurized liquid. (4) The present invention provides an integrated biogas biological desulfurization treatment device. During the rotation of the circular fixed rod, the circular lifting plate will also be driven to rotate. The circular lifting plate will drive the trapezoidal block 1 to rotate. The trapezoidal block 1 will contact the trapezoidal block 2 during rotation. When the trapezoidal block 1 contacts the trapezoidal block 2, the trapezoidal block 1 will rise. At this time, the trapezoidal block 1 drives the circular lifting plate to rise. The corresponding circular sleeve will also rise with the circular lifting plate. The circular sleeve will drive the filter plate to rise. The filter plate drives the annular vibration plate to rise. After the trapezoidal block 1 leaves the trapezoidal block 2, the trapezoidal block 1 will fall. At this time, the annular vibration plate will also fall. During this process, the filter plate forms an up and down reciprocating motion. During this process, several filter plates will vibrate. During the vibration process, the fine impurities and broken biofilms remaining in the filter plate holes will be shaken out and cleaned into the annular collection box with the help of the cleaning plate to avoid clogging of the filter plate, thereby further improving the desulfurization effect of the filter plate.

The water pump (4) extracts the liquid containing the desulfurization microorganisms in the bottom of the bioreactor (1) and inputs it into the transmission water tank (605). The liquid drives a plurality of transmission blades (608) to rotate. The transmission blades (608) drive the rotating shaft (607) to rotate. The rotating shaft (607) drives the rectangular lifting slide bar (701) to rotate. The rectangular lifting slide bar (701) drives the circular sleeve (501) to rotate. The circular sleeve (501) drives the hollow rectangular slide bar (502) to rotate. The hollow rectangular slide bar (502) The rotation generates centrifugal force, which swings the hollow rectangular slider (504) in a direction away from the circular sleeve (501). At the same time, the hollow rectangular slider (504) rotates, and the hollow rectangular slider (504) drives a plurality of round rods (505) to move. The round rods (505) rotate synchronously under the rotation of the hollow rectangular slider (504). The round rods (505) also rotate at the same time under the action of the cleaning brush (506). During the rotation of the cleaning brush (506), the biofilm generated in the air of the filter plate (503) is punctured and cleaned out. S2: When the hollow rectangular slider (504) moves away from the circular sleeve (501), the hollow rectangular slider (504) rotates and moves close to the annular mounting block (511) under the action of rotation. When the hollow rectangular slider (504) contacts the trapezoidal limiting plate (512) on the annular mounting block (511), the trapezoidal limiting plate (512) pushes the hollow rectangular slider (504) to move in a direction close to the circular sleeve (501) under the action of its inclined surface. After the hollow rectangular slider (504) passes the circular fixing rod (510), The hollow rectangular slider (504) will move in a direction away from the circular sleeve (501) under the action of centrifugal force, and the hollow rectangular slider (504) will then form a reciprocating motion.
