Description

Reclaim CO in the useless flue gas 2The system of gas generation tenaculat Habenaria
Technical field
The utility model relates to a kind of system that produces tenaculat Habenaria, particularly relates to CO in the useless flue gas of a kind of recovery 2The system of gas generation tenaculat Habenaria.
Background technology
At present, domestic a kind of method of producing tenaculat Habenaria is to build circulating culturing pool, at first in the pond, drops into nutrient solution and algae kind, and nutrient solution is by sodium hydrogencarbonate and water preparation.In the growth of spirulina platensis process, constantly add sodium hydrogencarbonate carbon source fertilizer and the microelement fertilizer that contains elements such as nitrogen, phosphorus, potassium, magnesium, zinc; After the tenaculat Habenaria maturation, circulate and gather, filter, dry; Promptly can be used as pharmacy and raw materials of food processing product sells; But this method production cost is high, CO 2Utilization ratio is low, and the water in the cultivation pool need carry out the periodicity discharging to be changed, and contains a large amount of sodium ions and various microelement fertilizer in the waste water of discharging, not only the water source of flowing through is caused severe contamination, and causes the waste of microelement fertilizer.Also have CO in the useless flue gas of recovery 2Or the CO that directly buys 2Directly feed and culture in the pond, but this method CO 2Utilization ratio is low, the yielding poorly of tenaculat Habenaria, and production cost is high.
In the drying process of tenaculat Habenaria, staple is CO in the coal-fired heating installation one hotblast stove tail end discharged flue gas of used oven dry 2, also have objectionable impuritiess such as sulphur, arsenic, dust.The way of present most of plant is coal-fired flue-gas directly to be discharged in the atmosphere or after simple dedusting discharge, and still ambient atmosphere is polluted.
The utility model content
The purpose of the utility model is to provide a kind of CO in the useless flue gas that makes full use of 2The system of gas generation tenaculat Habenaria.
The purpose of the utility model is implemented by following technical scheme, CO in the useless flue gas of a kind of recovery 2The system of gas generation tenaculat Habenaria; It comprises spirulina breeding pond, tenaculat Habenaria tripping device and liquid return tank; The filtrate outlet in said spirulina breeding pond is connected with the inlet of said tenaculat Habenaria tripping device; The filtrate outlet of said tenaculat Habenaria tripping device is connected with the inlet of said liquid return tank, and it also includes CO 2The absorption tower, said CO 2The filtrate outlet of bottom, absorption tower is connected the outlet of said liquid return tank and said CO with the filtrating inlet in said spirulina breeding pond 2The filtrating inlet on top, absorption tower connects said CO 2The bottom on absorption tower is provided with the gas inlet.
It also includes hotblast stove, drying tower, charging pump and CO 2Gas reclaiming purifying device, the flue outlet of said hotblast stove and said CO 2The inlet duct of gas reclaiming purifying device connects, said CO 2The outlet of gas reclaiming purifying device and said CO 2The gas inlet of bottom, absorption tower connects, the hot-wind inlet pipe connection of the hot-blast outlet of said hotblast stove and said drying tower, and the algae mud inlet of said drying tower is connected with the charging pump of said tenaculat Habenaria tripping device top.
The useless flue gas that the used hotblast stove of oven dry tenaculat Habenaria is discharged gets into CO 2Gas reclaiming purifying device is then through CO 2Obtain containing CO after the gas reclaiming purifying device purifying treatment 2The purified gas of gas more than 90%, purified gas is from CO 2The gas inlet of bottom, absorption tower is passed into CO 2In the absorption tower; Ripe spirulina liquor in the spirulina breeding pond feeds the tenaculat Habenaria tripping device; The algae mud that after the tenaculat Habenaria tripping device separates, obtains is squeezed in the drying tower through charging pump; The hot blast of hotblast stove is blown into the clay powder that must become to make a critical appraisal of of drying tower oven dry algae; Isolated filtrating gets into liquid return tank, and the filtrating in the liquid return tank is by CO 2The top filtrating inlet on absorption tower feeds CO 2The absorption tower, filtrating moves downward and CO 2Gas moves upward, filtrating and CO 2At CO 2Can fully contact in the absorption tower, filtrating fully absorbs CO 2After become saturated CO 2Filtrating is rich solution, and rich solution is by CO 2The bottom filtrate outlet on absorption tower flows back to the spirulina breeding pond and for producing tenaculat Habenaria carbon source is provided.
Can also be with the CO that buys or reclaim 2Gas directly feeds CO 2In the absorption tower.
The advantage of the utility model is, (1) CO 2Gas and filtrating are at CO 2Fully contact improves CO greatly in the absorption tower 2Gas effciency; (2) reclaim CO 2About 500 yuan per ton of gas cost, and CO 2Gas effciency can improve more than 50%, and tenaculat Habenaria output increases by 30%, reduces by 5000 yuan/ton of spirulina breeding costs; (3) fully recycle the useless flue gas that hotblast stove is discharged, reduce useless flue gas greatly atmospheric pollution, low-carbon environment-friendly; (4) the nutrient solution reusable edible in the breed pond avoids waste liquid to discharge polluted source, can make full use of the microelement fertilizer in the nutrient solution simultaneously, reduces production costs.
