New Multifunctional Wood Coconut Shell Horizontal Carbonization Furnace

Introduction:

horizontal dry distillation carbonization furnace is specially used for log, wood, jute stick, and other long rod-type biomass characteristics adopts a horizontal structure, cart entry, and exit raw material and the advanced hot gas dry carbonization process technology, using a unique carbonization flue gas (volatile hydrogen material and tar, etc.) Back Burning Technology, makes full use of the flue gas produced by the carbonization process, meets the thermal needs of the carbonization furnace itself, greatly increases the carbonization rate, the carbonization rate increased from 80% to more than 95%, and is easy to operate, safe,e and environmental protection, high production efficiency, can save a lot of energy, is the ideal equipment for carbonizing the long rod type biomass material. The combination mode of multiple devices, using carbonized flue gas in tandem, can reduce fuel consumption during carbonization production and improve the enterprise's benefit.

Technical parameter of Horizontal Carbonization Furnace:

Working principle :

A horizontal Carbonization Furnace is composed of a carbonization furnace body, furnace cover, inner tank, material cage, combustible gas return pipe, exhaust pipe, flue gas dust removal device, tank lifting device, and thermometer. The furnace adopts the principle of anaerobic dry distillation to remove the volatile substances in the biomass and achieve the purpose of biomass carbonization.
    The carbonization process has four steps: charging sealing furnace - preheat drying - anaerobic carbonization - and cooling carbon. A charging sealing furnace puts the biomass core rods, shells, and other materials into the cage. The cage is divided into two or three layers. In turn into the inner tank, cover, and lock the buckle, lifting the charging tank into the furnace.
    Preheat drying in the furnace with wood and other fuel heating, slowly heated from room temperature to 220-250 ℃, the processing time 1.2-2.0 hours (according to the material moisture content, density, particle size determines the specific heating time), and discharge the material moisture and the air in the tank. Anaerobic carbonization is the furnace temperature to the beginning of weak yellow smoke in the smoke pipe (hydrogen and other volatile substances) discharge, that is the beginning of carbonization, recovery of combustible gas into the furnace ignition, adjusting intake air, maintaining the tank temperature 300-450 ℃ for 2.0-3.5 hours (according to the carbonized material density, particle size, and carbonization depth requirements determine the specific temperature and carbonization time).
    When the furnace is natural flameout, namely for the end of carbonization. Cooling out the carbon hanging out of the tank from the furnace, into the cooling area of natural cooling or spray water cooling, until the inner tank temperature drops to below 50 ℃, then open the cover out of charcoal. The total furnace temperature and carbonization time are 3.5-5.5 hours. It can complete 3-6 furnace times in 24 hours. Exhaust gas through dust collector treatment to reach discharge standards. 3 sets of carbonization furnaces in parallel use, peak shifting carbonization, which can be completely used volatile gas heating carbonization furnace, without using additional fuel.
