Straw power generation dense combustion unit

Abstract

The invention relates to the field of straw combustion treatment, in particular to a straw power generation dense combustion unit. A smoke purification mechanism, a combustion supporting mechanism, aprotection mechanism, an inner container and a discharging hopper are included. A rotation mechanism and a waste heat recycling mechanism are further included. Through the smoke purification mechanism, combustion parameter smoke purification is achieved; the combustion supporting mechanism is used for providing a fire source for the interior; the protection mechanism prevents heat losses, and meanwhile safety performance is improved; combustion is convenient through the inner container, and the discharging hopper conveniently collects combustion materials; and the rotation mechanism can provide oxygen for combustion, meanwhile, stirring is strengthened, garbage is conveniently distributed on the surface of a filter net, and the waste heat recycling mechanism achieves waste heat recycling.By means of the straw power generation dense combustion unit, sufficient straw combustion can be ensured, the combustion efficiency is high, heat can be efficiently recycled during combustion, and meanwhile pollution to the environment during combustion is reduced.

Description

technical field [0001] The invention relates to the field of straw combustion treatment, in particular to a compact combustion unit for straw power generation. Background technique [0002] Straw is the general term for the stems and leaves (ears) of mature crops. It usually refers to the remaining part of wheat, rice, corn, potato, rapeseed, cotton, sugar cane and other crops (usually coarse grains) after harvesting the seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content (30%-40%), and contains lignin and so on. Although lignocellulose cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. [0003] The traditional method of straw treatment is direct combustion,...

AI Technical Summary

Problems solved by technology

[0003] The traditional method of straw treatment is direct combustion, which causes a lot of pollution. The existing straw is disposed of by landfill and incineration. During the incineration, the straw is difficult to enter the air due to its sealing performance, and the combustion is not sufficient. The efficiency is low, and the heat recovery efficiency generated by combustion is low at the same time, and the heat of combustion cannot be utilized
