Abstract
The invention relates to a rice husk suspension combustion method which comprises the steps of airing rice husk firstly, pulverizing blocks, and stacking up to be used as fuel; putting the rice husk into a combustion chamber of a boiler to be combusted, wherein air blowers are arranged at the periphery of the combustion chamber and are connected into the combustion chamber by pipes; starting the air blowers during combustion of the rice husk so as to blow air into the combustion chamber through the pipes to blow combusting rice husk to be suspended; enabling the combusted rice husk to enter the chimney to be subjected to sedimental collecting treatment, wherein the suspended rick husk can be sufficiently combusted due to contact with fresh air in the combustion chamber; turning off the air blowers after combustion is completed. The rice husk suspension combustion method has the advantages of simplicity, low cost and the like, the rice husk is combusted sufficiently, the resource utilization rate is high, and the combustion process is safe and reliable.
Description
Technical field
The present invention relates to living resources and utilize technical field, be specifically related to a kind of rice husk suspension combustion method.
Background technology
Paddy rice is the crops that cultivated area is the widest in the world, output is maximum.Nearly 600,000,000 tons of current whole world paddy total output, and approximately 200,000,000 tons of China's total outputs.In paddy, rice husk accounts for 20%.Although the rice husk resource of China is very abundant, present utilization rate is very low.Be used to the animals feed at the rural area rice husk, but, because its nutrient composition content is very low, add the rice husk surface by the fine and close covering of lignin, crude fibre is tightly surrounded, so animals is taken in total digestibility, can only reach 5%-8%.Therefore the rice husk major part abandons as refuse or is used as inferior fuel, and this is contaminated environment not only, and has caused the waste of resource.In cities and towns rice processing factory, a large amount of rice husks is piled up, and utilization rate is also very low, and the overwhelming majority is all directly burned.Because dioxide-containing silica in rice husk is higher, rice husk is difficult to sufficient combustion, so except discharging great amount of carbon dioxide in atmosphere, also produce simultaneously a large amount of dust.
Really can consume in a large number at present rice husk to utilize approach to only have single with the technology mode of rice husk as direct fuel, but, this technology with combusting rice hull exists calorific value to transform the handling problems of low, coking fouling, dust, rice hull ash, because burn incompletely can produce fuel gas, the possibility of blasting is arranged, therefore, how allowing rice husk burn fast and effectively is the application's problem to be solved.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of method simple, can effectively improve the rice husk suspension combustion method of combusting rice hull rate.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of rice husk suspension combustion method, comprise the following methods step,
1) at first the rice husk airing is done, caking caking is pulverized arranged, heap is used as fuel and uses;
2) burn in the combustion chamber of rice husk being put into boiler, the surrounding in combustion chamber is provided with air blast, and air blast is linked in combustion chamber by pipeline;
3) in the combusting rice hull process, start air blast, air blasts combustion chamber by pipeline, and aflame rice husk is blown out suspension;
4) rice husk of suspension, owing to touching fresh air, just can fully burn in combustion chamber, and the rice hull ash after burning enters into chimney and carries out the sedimentation collection and treatment;
5) close air blast after burning is completed.
The invention has the beneficial effects as follows: the advantages such as it is simple that the present invention has method, with low cost, can make rice husk fully burn, resource utilization is high, and combustion process is safe and reliable.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand,, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
A kind of rice husk suspension combustion method, comprise the following methods step,
1) at first the rice husk airing is done, caking caking is pulverized arranged, heap is used as fuel and uses;
2) burn in the combustion chamber of rice husk being put into boiler, the surrounding in combustion chamber is provided with air blast, and air blast is linked in combustion chamber by pipeline;
3) in the combusting rice hull process, start air blast, air blasts combustion chamber by pipeline, and aflame rice husk is blown out suspension;
4) rice husk of suspension, owing to touching fresh air, just can fully burn in combustion chamber, and the rice hull ash after burning enters into chimney and carries out the sedimentation collection and treatment;
5) close air blast after burning is completed.
Above demonstration and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
