Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is done further details of elaboration, but embodiments of the present invention are not limited to the scope that embodiment represents.These embodiments are merely to illustrate the present invention, not for restriction the scope of the present invention. Additionally, after reading present disclosure, the present invention can be done various amendment by those skilled in the art, and these equivalent variations fall within appended claims limited range of the present invention equally.
One, the preparation process of the combustion-supporting material of biology of the present invention.
The preparation method of the combustion-supporting material of biology of the present invention is basic as it is shown in figure 1, concrete technology is as follows:
Step 1, material prepare
1) stand-by free of contamination sucrose solution (adopting the common useless sucrose solution that sugar enterprise produces) is prepared;
2) free of contamination water (being used without the subsoil water polluted) to be diluted is prepared;
3) prepare stand-by leaven (be made up of rhodospirillum, azotase, hydrogen enzyme, by weight consumption account for total raw material 1-1.5%);
4) stand-by saccharifying body (azotase is mixed into bagasse by the addition of 1% and mixes, and consumption accounts for the 0.0075% of total raw material by weight) is prepared.
Step 2, appliance device prepare
1) fermentation tank vapor sterilization;
2) check whether have foreign body inside fermentation tank, it is to avoid blocking valve, check whether each valve closes;
3) light compositing lamp is installed.
Step 3, sweat
1) sucrose solution is configured to rare sucrose solution of sugary 10-12%, opens steam and sucrose solution is heated to 45 DEG C from room temperature, join in fermentation tank, account for the 80-90% of volume in fermentation tank;
2) leaven of mix homogeneously being divided into three parts, in point three input fermentation tanks, the release time is as far as possible short;
3) drive air compressor and stir sucrose solution, leaven is uniformly mixed in sucrose solution, it is ensured that the leaven in fermentation tank all sinks in sucrose solution;
4) put into saccharifying body, open photosynthetic lamp;
5) closing dog-house, close valve, after sealing, every day is by detecting hole observation fermentation situation, and every day chemically examines fermentation liquid twice, and record includes six indexs such as sugar part, brix, temperature, pH value, lactic acid, acetic acid;
6) when Testing index reaches following table standard, representing fermenting-ripening, carry out solid-liquid separation, filtering residue is dried can as feedstuff, filtrate and the combustion-supporting material of biology of the present invention.
| Project | Index |
| Acetic acid | �R2000.0mg/L |
| Lactic acid | �R2000.0mg/L |
| Reducing sugar | 10.0% |
| PH value | 3.5��0.3 |
| Brix (densimetry) | �R17.0/��Bx |
Two, the result of use checking of the combustion-supporting material of biology of the present invention.
By the steam boiler of products application obtained above to burning coal, coal-fired consumption, steam production and discharge capacity are calculated.
Different according to the ratio putting into the combustion-supporting material of biology of the present invention, altogether carry out four combustion tests: experiment one: burning coal 20 tons, be not added with combustion-supporting material; Experiment two: burning coal 20 tons, the combustion-supporting material that adds 0.3% by weight; Experiment three: burning coal 20 tons, the combustion-supporting material that adds 0.5%; Experiment four: burning coal 20 tons, the combustion-supporting material that adds 0.75%. Combustion experiment is at boiler advanced combustion, reaches under the operating mode of hot stable state, adds 20 tons of coals and continuously performs and carry out combustion experiment. The coal supply speed of experiment is definite value, exhaust steam pressure and temperature every time is definite value, and in four combustion experiments shown in the curve of boiler steam discharge amount and time relationship such as Fig. 2-5, wherein vertical coordinate is discharge of steam amount, and unit is ton hour; Abscissa is time coordinate, and 4 hours stable states of experiment extraction are recorded every time, the data recorded once for every 10 minutes.
1) steam production contrast in equal coal-fired situation:
Experiment one: burning coal 20 tons, is not added with combustion-supporting material, and this group is as a control group;From the experimental record data of Fig. 2 it can be seen that average discharge is about 20 tphs.
Experiment two: burning coal 20 tons, the combustion-supporting material that adds 0.3% by weight; From Fig. 3 experimental record data it can be seen that average discharge is about 21 tphs. The comparing in this stage exceeds 1 ton hour according to group steam flow.
Experiment three: burning coal 20 tons, the combustion-supporting material that adds 0.5% by weight; From Fig. 4 experimental record data it can be seen that average discharge is about 22 tphs. The comparing in this stage exceeds 2 ton hour according to group steam flow.
Experiment four: burning coal 20 tons, the combustion-supporting material that adds 0.75% by weight. From the experimental record data of Fig. 5 it can be seen that average discharge is about 21 tphs. The comparing in this stage exceeds 1 ton hour according to group steam flow.
2) test boiler emission situation to 4 times to be monitored: predominantly detect the emission behaviour of PM10 and PM2.5 in aforementioned four is tested, see following table:
From above detection data it can be seen that with the addition of the fire coal of the combustion-supporting material of biology provided by the invention, PM10 and the PM2.5 content in post combustion emission thing all significantly reduces.
3) 4 times are tested other condition monitoring situation of boiler operatiopn:
| Experiment group | Fire box temperature | Slag phosphorus content | Ash phosphorus content |
| Experiment one (being not added with) | 690 | 8% | 7% |
| Experiment two (adding 0.3%) | 900 | 2.5% | 2% |
| Experiment three (adding 0.5%) | 880 | 2% | 1.5% |
| Experiment four (adding 0.75%) | 950 | 1.5% | 1.5% |
The comprehensive above Comparability test that burns, it can be seen that with the addition of the fire coal of charcoal element hydrogen, fire coal makes consumption can reduce 5%-10%, and the PM2.5 of boiler smoke can reduce by 50%��80%, fire box temperature improves about 30%, and the remaining slag that burns significantly declines with ash phosphorus content.
The present embodiment purpose is in that to make professional and technical personnel in the field can understand technical scheme according to it and be carried out; the protection domain of this patent can not be limited with it; all deformation made according to present disclosure technology, each fall within protection scope of the present invention. Protection scope of the present invention is as the criterion with content described in claims.
