Abstract

The present invention relates to a solar-driven biomass utilization and carbon capture system. Biogas enters a CO2 absorption tower from the bottom through an induced draft fan, and low-temperature water is sprayed down from the top of the absorption tower at a high speed. The gas-liquid contact area is increased by gas-liquid countercurrent. The CO2 absorption tower contains a large amount of fillers to further increase the overall contact area of ​​the gas and liquid. After the biogas and low-temperature water contact in the CO2 absorption tower, the low-temperature water absorbs CO2 in the biogas to become a rich liquid containing a large amount of CO2. The rich liquid is passed into a CO2 regeneration tower, and is heated to 100 to 120° C. in the CO2 regeneration tower, so that the rich liquid decomposes and releases CO2 absorbed in the low-temperature water. CO2 can be passed into a greenhouse to enhance plant photosynthesis, and the purified CH4 is sent from the top of the tower to a biogas motor for power generation, and finally methanol purification and carbon dioxide recovery are achieved. The present invention realizes the application of the resource utilization mode of biomass driven by solar energy in the greenhouse, can effectively adjust the CO2 concentration in the greenhouse, and fully improves the growth environment of plants.

A liquid feed inlet 10 connected to the solid-liquid separator 1 pipeline is provided on the top of the anaerobic fermentation tank 9, and a pump II7 is provided on the pipeline.

[0031] The biogas purification-CO2 recovery system comprises a CO2 absorption tower 12, a CO2 regeneration tower 18 and a high-temperature gas tank 21. A biogas motor 32 is provided on the connecting pipeline between the top of the CO2 absorption tower 12 and the vegetable greenhouse 46. A first heat exchanger 16 is provided on the pipeline between the bottom of the CO2 absorption tower 12 and the upper part of the CO2 regeneration tower 18. The anaerobic fermentation gas generated in the anaerobic fermentation tank 9 enters from the bottom of the CO2 absorption tower 12. Cold water of the first heat exchanger 16 is sprayed from the upper part of the CO2 absorption tower 12.

The CO2 gas storage tank 19 is connected to the vegetable greenhouse 46 pipeline, and the high-temperature gas tank 21 passes the high-temperature gas from the bottom of the CO2 regeneration tower 18 to heat the CO2 rich liquid.

[0032] The methanol chloride heat pump system comprises a solar collector 28, a second heat exchanger 22 and a condenser 27. The second heat exchanger 22 is filled with a calcium chloride dimethanol complex 30, and the condenser 27 is filled with anhydrous CaCl2 31.

Both ends of the second heat exchanger 22 are respectively connected to the condenser 27. A methanol tank 26 and an expansion valve 29 are sequentially arranged on the pipeline from the second heat exchanger 22 to the condenser 27.

[0033] The greenhouse fertilizer monitoring system includes a vegetable greenhouse 46 with a soil layer 43, a compost aerobic fermentation tank 45 feeds solid fertilizer into the vegetable greenhouse 46, an anaerobic fermentation tank 9 feeds liquid fertilizer into the vegetable greenhouse 46, and lighting lamps 33 powered by a biogas motor 32 are arranged at intervals on the inner wall of the vegetable greenhouse 46. A waterproof layer 40 is arranged inside the soil layer 43 in the vegetable greenhouse 46, and a primary battery device is arranged above the waterproof layer 40, which is a Cu-FeCl3-C primary battery.

[0034] The usage process is as follows:

[0035] like Figure 1 As shown, biomass materials are put into the material inlet at the upper end of the solid-liquid separator 1. First, the vibrating rod 3 drives the vibrating screen 4 to vibrate and filter large-diameter biomass materials, while the small-diameter biomass materials and liquid biomass fertilizer continue to fall downward to the elastic filter cloth 2. After being filtered by the elastic filter cloth 2, the liquid biomass fertilizer falls to the adsorption baffle 5 at the bottom of the solid-liquid separator 1. After the adsorption baffle 5 filters the sludge in the liquid biomass fertilizer, the solid fertilizer is driven by the pump I6 to be sent to the compost aerobic fermentation tank 45, and the liquid fertilizer is driven by the pump II7 to be sent to the anaerobic fermentation tank 9.

[0036] The solid fertilizer in the solid-liquid separator 1 is delivered to the solid feed port 51 at the top of the compost aerobic fermentation tank 45 by pump I6, and the air in the aeration system 48 is delivered to the vent pipe 23 driven by pump X47, and the vent pipe 23 delivers the air evenly into the compost aerobic fermentation tank 45 for aerobic fermentation of the solid fertilizer, and uses the anchor stirring paddle 34 to stir the solid fertilizer evenly to enhance the aerobic fermentation effect. After the aerobic fermentation of the solid fertilizer is completed, the valve I25 is opened, and the solid fertilizer in the compost aerobic fermentation tank 45 is delivered to the vegetable greenhouse 46 through the solid discharge port 35 to fertilize the soil.

[0037] like Figure 1 , Figure 2As shown, pump II7 inputs the liquid fertilizer in the solid-liquid separator 1 into the anaerobic fermentation tank 9 through the liquid feed port 10 at the top of the anaerobic fermentation tank 9 for anaerobic fermentation of biomass. The anaerobic fermentation gas produced by the fermentation mainly contains CH4 and CO2. The anaerobic fermentation gas is introduced into the CO2 absorption tower 12 through the anaerobic fermentation gas inlet 12-2 at the bottom of the CO2 absorption tower 12, and keeps flowing from bottom to top. Under the driving action of pump V14, the CO2 lean liquid (heat source) passing through the first heat exchanger 16 is discharged from the CO2 lean liquid 16. The liquid inlet 12-4 enters the CO2 absorption tower 12 and sprays down from the top of the CO2 absorption tower 12. The CO2 is absorbed by the CO2 lean liquid and flows out from the CO2 rich liquid outlet 12-3 at the bottom of the CO2 absorption tower 12. The outflowing rich liquid (cold source) flows back to the first heat exchanger 16 under the drive of the pump VI15. The CH4 that is not absorbed by the CO2 lean liquid is dried by the first drying device 36 and flows from the methane gas outlet 12-1 at the top of the CO2 absorption tower 12 to the biogas motor 32 to generate electricity to power the lighting lamp 33.

[0038] like Figure 1 , Figure 3 As shown, the left side of the CO2 regeneration tower 18 is the CO2 rich liquid inlet 18-1, which is connected to the first heat exchanger 16. The preheated CO2 rich liquid is transported from the first heat exchanger 16 to the CO2 rich liquid inlet 18-1 by the pump IV13; the right side of the bottom of the CO2 regeneration tower 18 is the high-temperature gas inlet 18-3 connected to the steam tank 21, and the high-temperature steam flows from the high-temperature gas inlet 18-3 from bottom to top. The CO2 rich liquid enters the CO2 regeneration tower 18 after preheating and is quickly decomposed into CO2 gas and H2O through the negative pressure heating operation mode. Driven by the pump VII17, the H2O flows back to the first heat exchanger 16 from the CO2 lean liquid outlet 18-2. After being dried by the second drying device 38, the CO2 gas flows into the CO2 gas storage tank 19 from the CO2 gas outlet 18-4. The CO2 is collected by the CO2 gas storage tank 19 and is passed into the vegetable greenhouse 46 driven by the pump VIII20 to enhance plant photosynthesis. The operating temperature of the CO2 regeneration tower 18 is 65°C to 120°C, and the preheating temperature of the washed CO2 lean liquid is 40°C to 48°C.

[0039] The solar collector plate 28 provides water at about 130° C. for the second heat exchanger 22, and heats and decomposes the calcium chloride dimethanol complex 30 inside the second heat exchanger 22 into anhydrous CaCl2 31 and gaseous methanol at a temperature of about 120° C. The gaseous methanol is sent to the methanol tank 26, and the gaseous methanol enters the condenser 27 after passing through the expansion valve 29 to react with the anhydrous CaCl2 31 to release heat, and the heat is transferred to the air in the steam tank 21 through the condenser 27. The calcium chloride dimethanol complex 30 after the complex reaction is driven by the pump IX24 to the second heat exchanger 22, completing a chemical heat pump cycle.

[0040] like Figure 1 , Figure 4 As shown, the galvanic cell device buried inside the soil layer 43 in the vegetable greenhouse 46 is a Cu-FeCl3-C galvanic cell. When the reaction water 37 carried by the liquid biomass fertilizer infiltrating the groove 44 inside the soil layer 43 is too much, the reaction water 37 will penetrate the entire galvanic cell solution pool, and the anhydrous ferric chloride powder 39 will turn into ferric chloride solution when it meets water, thereby activating the galvanic cell reaction and generating current to activate the ammeter to work, reminding the fruit farmers that there is too much liquid fertilizer inside the soil layer 43. Among them, the copper rod 41 is the positive electrode, the carbon rod 42 is the negative electrode, and the copper rod 41 and the carbon rod 42 are connected to the ammeter respectively. The waterproof layer 40 is set in the deep soil layer to prevent the loss of fertilizer.
