The invention has the advantages of ingenious design and reasonable design, does not need to add a complex emission reduction device, can replace the combustion of biomass fuel by the released heat through the secondary utilization of waste gas, can effectively reduce the emission of the waste gas, reduce the air pollution, meet the environmental protection requirement, improve the utilization rate of hot air and obviously reduce the production cost.
Description
Technical Field
The invention belongs to the field of waste gas treatment, and particularly relates to a waste gas circulation method of a biomass hot blast stove.
Background
Because China is in the industrialized and urbanized accelerated development stage, the energy consumption intensity is higher, the consumption scale is continuously enlarged, and particularly, the extensive economic growth mode of high investment, high consumption and high pollution aggravates the contradiction between energy supply and demand and the environment pollution condition. The energy problem becomes an important factor restricting economic and social development, the importance of well-done energy work is fully known from the strategic and global height, the energy safety is highly emphasized, and the sustainable development of energy is realized.
The biomass energy is a high-quality fuel, and has the effects of energy conservation and environmental protection compared with energy sources such as petroleum, natural gas, coal and the like, but the biomass fuel generally has the characteristics of high water content, large size change of the fuel, high ash content and the like, so that the fuel cannot be completely combusted. At present, the hot blast stove using biomass as fuel has obvious defects, especially, the discharged waste gas is large, the pollution is serious, and the requirements of environmental protection are not met.
Disclosure of Invention
The invention aims to provide a waste gas circulation method of a biomass hot blast stove, which aims to reduce waste gas emission, secondarily utilize waste gas, meet the requirement of environmental protection and reduce the production cost.
In order to achieve the above purpose, the solution of the invention is:
a waste gas circulation method of a biomass hot blast stove comprises the following steps:
step 1, collecting waste gas discharged from an outlet of a biomass hot blast stove;
step 2, feeding the waste gas into an inlet of the hot blast stove again by means of a fan;
and 3, mixing the waste gas with hot flue gas from the front-mounted combustion furnace and then supplying the mixture to the hot blast stove, so that the hot blast stove can reuse the mixture.
After the scheme is adopted, the invention has the following beneficial effects:
the invention has the advantages of ingenious design and reasonable design, does not need to add a complex emission reduction device, can replace the combustion of biomass fuel by the released heat through the secondary utilization of waste gas, can effectively reduce the emission of the waste gas, reduce the air pollution, meet the environmental protection requirement, improve the utilization rate of hot air and obviously reduce the production cost.
Detailed Description
The technical solution of the present invention will be described in detail with reference to the following specific examples.
The invention provides a waste gas circulation method of a biomass hot blast stove, which comprises the following steps:
step 1, collecting waste gas discharged from an outlet of a biomass hot blast stove, wherein the temperature of the waste gas is controlled at 110-130 degrees;
step 2, feeding the waste gas into the inlet of the hot blast stove again by means of a fan, and reducing the temperature of the waste gas to 80-100 degrees;
and 3, mixing the waste gas with hot flue gas from the front-mounted combustion furnace and then supplying the mixture to the hot blast stove, so that the hot blast stove can be reused, the air supply time is 120-395 ℃ and the temperature is raised to 375-395 ℃.
The invention has the following beneficial effects:
the invention has the advantages of ingenious design and reasonable design, does not need to add a complex emission reduction device, can replace the combustion of biomass fuel by the released heat through the secondary utilization of waste gas, can effectively reduce the emission of the waste gas, reduce the air pollution, meet the environmental protection requirement, improve the utilization rate of hot air and obviously reduce the production cost.
The above embodiments are only for illustrating the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and any modifications made on the basis of the technical scheme according to the technical idea of the present invention fall within the protection scope of the present invention.
