Sealed feeding device for pyrolysis carbon gas combined production and feeding method of sealed feeding device

Abstract

The invention discloses a sealed feeding device for pyrolysis carbon gas combined production and a feeding method of the sealed feeding device. The sealed feeding device comprises material conveying barrel bodies, a mechanical executing mechanism, a sealed hopper and a material collector. The material conveying barrel bodies are made from national standard stainless steel pipes, and two material barrels are adopted to be arranged in parallel; the crank connection rod principle is applied by the mechanical executing mechanism, and a connection rod is connected with a transmission mechanism anda pushing piston; a high-frequency vibrator is arranged on the sealed hopper; the material collector is connected with the two material conveying barrels; and a lower discharging port is connected with a biomass pyrolysis furnace. According to the sealed feeding device for pyrolysis carbon gas combined production and the feeding method of the sealed feeding device, the design of dual sealing is adopted, and a long material layer in the material conveying barrels forms a secondary material sealing layer while materials in the hopper form a primary material seal; meanwhile, due to the special design of the double material barrels, the requirement of the device for continuous and uniform material conveying can be well met, the problems that due to the single-material-barrel design, interrupting of material conveying is caused during pumping of a piston, and the treatment effect of the biomass pyrolysis furnace is affected are solved, meanwhile, the material conveying efficiency of the device is improved, and the overall process level is improved to a certain extent.

Description

technical field [0001] The patent of the present invention relates to a sealed feeding device for pyrolysis carbon gas cogeneration and its feeding method, especially for sealed feeding of devices such as biomass pyrolysis furnaces and coal gasification furnaces that require air isolation. Background technique [0002] As a traditional large agricultural country and a large coal consumption country, our country produces more than 900 million tons of crop straw every year, and the total coal consumption reaches 4.3 billion tons. At present, the potential of my country's usable biomass resources to be converted into energy is about 500 million tons of standard coal. With the expansion of afforestation area and economic and social development, the potential of my country's biomass resources into energy can reach 1 billion tons of standard coal, accounting for 28% of my country's total energy consumption, but due to the large amount of biomass resources, high utilization costs, a...

Problems solved by technology

[0003] In the process of biomass pyrolysis and coal gasification, the interior of the reactor is usually required to maintain a low oxygen or anaerobic state. On the one hand, air entering the reactor will cause deflagration or even explosion accidents, and on the other hand, it will cause high oxygen content in the produced gas. , low calorific value, and reduce the safety of the gas storage produced, this problem seriously hinders the popularization and application of biomass pyrolysis and coal gasification technology

The main reason for the excessive oxygen inside the reactor is that during the conveying process, the seal of the conveyer is not good, and the air enters the reactor with the material
