Problems solved by technology

[0015] 1. The moisture and gas carried by the fuel are mixed into the pyrolysis steam, which reduces the quality of the pyrolysis steam
[0016] 2. Many solutions cannot be scaled up, the output is very low, the industrial scale cannot be formed, the cost is high, and it cannot replace fossil fuels
[0017] 3. Many schemes cannot output heat energy, and some schemes can have a cooling water jacket outside the combustion chamber to output cooling tail water. However, for the heat energy (steam) required by most users, an additional gas boiler is required

specific Embodiment

[0040] Use the pulverizer 12 to pulverize the biomass fuel and send it to the buffer bin 11, start the drying fan 14, blow in the drying air (adjust the flue gas to 150°C), start the feeder 13, and send the fuel into the drying (lifting) tower 10, the drying air sends the fuel into the silo 1, and at the same time, it exchanges heat with the fuel to dry the fuel, the drying air is discharged from the drying air outlet 2, the fuel falls into the bottom of the silo, and the screw conveying device is started 15. At the same time, the medium oil with a temperature of about 200°C is sent from the medium oil inlet 9, the medium oil is mixed with the fuel, and pushed into the filter press device 17, the medium oil is immersed in the structure of the fuel and the temperature of the fuel is raised to close to the pyrolysis reaction critical temperature, forming a mixture composed of fuel, gas and medium oil. During the process of propulsion, the gas is discharged from the sieve, and ent...

Abstract

This invention relates to a boiler pyrolyzing biomass fuels to generate biooil, combustible gas, active carbon and heat energy composed of a supplying system, an outer pyrolysis device, a heat exchange pyrolysis device and a boiler, in which, its supplying system can dewater, degas, rise the temperature to let its energy density the maximum, the outer heat pyrolysis device can quickly pyrolyze the prepared fuels to generate pyrolysis steam at 900deg.C to be used by the heat exchange device to pyrolyze biomass materials without O2 to generate semi-coke used in producing active carbon.

Description

Technical field: [0001] The invention relates to a boiler, especially a boiler capable of co-producing bio-oil, combustible gas, activated carbon and heat energy by pyrolysis and vaporization of biomass fuel. Background technique: [0002] At present, the utilization of biomass fuels has attracted widespread attention from all countries in the world, and various research work has been carried out and some results have been obtained. [0003] Solar energy stores biological energy in biomass through photosynthesis. According to growth and storage conditions, biomass has different types, including: 1. Naturally growing terrestrial plants and aquatic plants; 2. Artificially planted agricultural By-products, such as straw, etc.; 3. End products after processing agricultural products, such as rice husk, sugar residue, etc.; 4. End products (garbage) after humans use agricultural products. These substances have stable quality and high energy, and can be converted into solid, liqui...
