USE - A multi-functional biomass conversion counter heating system.    DETAILED DESCRIPTION - A multi-functional biomass conversion counter heating system comprises a counter heating furnace (1), a water storage buffer tank (10), pipeline pump (11) and heating device (12). The counter heating furnace is provided with a vertical storage hopper. The top of the storage bin is provided with a storage bin cover of the storage hopper. The lower part of the pyrolysis chamber, pyrolysis chamber and counter heating furnace of the bottom of the combustion chamber are provided with grate. The heat exchange chamber between the inner wall of the storage bin and the counter heating furnace body is respectively provided with a water inlet on the heat exchange chamber sidewall (502) and water outlet (503). A water outlet is provided through the water storage buffer tank. The pipeline pump and heating device are connected to the water inlet. A heat exchange chamber is provided with a gas buffer chamber. The heat exchange chamber and the bottom of the combustion chamber are provided with an air inlet channel. The pyrolysis chamber of the wall of the combustion chamber is distributed with air inlet passage connected with the air outlet. The heat exchange chamber and the counter heating furnace between the combustion chamber on wall of the furnace body are provided with an air inlet and a carbon discharging opening. An air inlet is connected with the air inlet channel. A carbon outlet is provided through the guide tube. The pyrolysis chamber is provided with a heat exchange pipe in the heat exchange chamber. The heat exchanging pipe is connected with the air buffer chamber, and the other end passes through the air inlet channel connected with the combustion chamber. The top of the airflow buffer chamber is provided with a chimney.
