Description

A kind of automatic feed/discharge is biomass carbonated-cooling integration self-heating apparatus

Technical field

The utility model relates to a kind of biomass charing devices, and in particular to and a kind of continuous biomass carbonizes-cool down one Body self-heating apparatus, it belongs to agriculture and forestry organic waste material resource utilization and biomass high-temperature pyrolysis technology field.

Background technique

Biomass carbonated to refer under anaerobic or low-oxygen environment, biomass, which is heated up, causes molecular cleavage to generate biology The process of charcoal, condensable liquid and fuel gas.Charcoal is widely used in metallurgy, chemical industry, national defence, agricultural and environmental protection etc. Aspect；Condensable liquid includes wood vinegar and wood tar, and wood vinegar is a kind of natural plant growth regulator, has and promotes to plant The multiple efficacies such as object growth, sterilization, insect prevention, anti-corrosion, deodorization, improvement soil environment；Wood tar is that production waterproof, corrosion-resistant are high-quality Industrial chemicals, the country are mainly used for antioxidant and polymerization inhibitor in rubber production；Fuel gas mainly includes CO, H2 and CH4 etc. Component, single cube of calorific value can achieve 15 MJ, as a kind of clean energy resource, can carry out central gas supply for rural area.

The biomass carbonated method being most widely used in production is mostly external-heat heating, i.e., material and heat source separate, Reaction kettle outer wall is heated, by the heat transfer between kettle wall and material and material inside, realizes that biomass is thermally decomposed. But since biomass thermal conduction efficiency is low, cause the reaction time long, pyrolysis energy consumption increases, and carbonizes the high heating value fuel gas of generation Often over air is directly discharged to after washing, not only waste of resource but also environment has been polluted.In addition, the charcoal just generated is due to tool There is higher temperature, can not directly collect removal, frequently with natural cooling method in production, it is therefore desirable to when extremely long cooling is detained Between, whole cooling effect is very poor, seriously affects production efficiency.

In order to solve the above problems, people are seeking always a kind of ideal technical solution.

Summary of the invention

Purpose of the utility model is to overcome the above-mentioned shortcomings and provide an automatic feed/discharge it is biomass carbonated-cooling integrated Change self-heating apparatus, the input of the raw material and carbonizing production of continous way and batch two ways can be realized using spiral conveyer structure And output, raw material is heated by heater strip, raw material starts spontaneous combustion generation heat under aeration condition and raw material is promoted to carbonize, When the combustible fumes that charing generates, which enters burner hearth by smoke backflow pipeline, carries out burning maintenance raw material charing, stop electric heating It ventilates with to raw material, the hot charcoal of generation is quickly cooled down by cooling zone, and it is small to form a kind of energy consumption, self-loopa and side easy to operate Just high-efficient homework device.
