Biomass dry distillation type cracking furnace

Abstract

The invention discloses a biomass dry distillation type cracking furnace. The biomass dry distillation type cracking furnace comprises a feeding unit, a carbonization unit and a separation and recycling unit; the feeding unit comprises a spiral feeder; the carbonization unit comprises a feeding port, a carbonizer, a cooler and a discharging port which sequentially communicate with one another; thecarbonizer and the cooler are tubular, and a raw material conveying propeller is arranged inside each of the carbonizer and the cooler; the separation and recycling unit comprises a fine powder separator which communicates with an exhaust port and a flue gas condenser which communicates with the upper end of the fine powder separator; the lower side of the flue gas condenser communicates with a flue gas filter; and a negative pressure fan is arranged on the lower side of the flue gas filter. The biomass dry distillation type cracking furnace has the advantages that the recycled carbon powderis pure, and the carbon yield is high; the heat value of the recycled gas is high; cyclic production without stopping is realized, and the working efficiency is improved; and zero emission is realizedin the whole cracking process, and environmental pollution is completely eradicated.

Description

Technical field [0001] The invention belongs to the technical field of dry distillation, and specifically relates to a biomass dry distillation cracking furnace. Background technique [0002] Energy is an important material basis for the existence and development of human society. At present, the world energy structure is dominated by fossil energy sources such as coal, oil and natural gas. Fossil energy is a non-renewable resource, and a large amount of consumption will eventually be exhausted, and a large amount of pollutants are discharged during the production and consumption process, destroying the ecology and the environment. Today, when the global energy situation is tense and global warming is a serious threat to economic development and people’s health of life, countries all over the world are seeking new energy alternative strategies in order to achieve sustainable development and gain an advantageous position in future development. The development of renewable energy...

Problems solved by technology

[0004] At the same time, the negative pressure anti-fire orange straw gasification technology popularized and applied in my country at the present stage, because the combustible gas produced has a low calorific value, the product is single, and the economic effect is not good, resulting in the use of state financial subsidies. "Biomass gasification station" is in a state of shutdown or semi-stop production. Examining the current domestic biomass carbonization gas production equipment, all of them belong to the type of intermittent carbonization technology, such as pile firing method, kiln firing method and external heating type carbonization kettle

Due to the operation method of intermittent feeding, gas production and charcoal production, the production efficiency is low, the waste of heat energy is serious, the labor intensity of the operators is high, the working environment is poor, and the toxic combustible gas containing a certain concentration is periodically discharged intermittently. The surrounding atmospheric environment causes pollution to varying degrees
