Specific embodiment

Embodiment 1

The embodiments of the present invention 1 are described in detail with reference to the accompanying drawing.

The utility model is the material drying system before a kind of gasification of biomass, includes condenser 1, compression referring to attached drawing 1 Machine 2, evaporator 3, expansion valve 4, dry and cold intake stack 5, xeothermic wind pipe 6, pre-dryer 7, damp and hot wind pipe 8, water outlet Pipe 9, biomass processes and conveying equipment 10, gasification furnace 11, deduster 12, washer 13, drier 14, air-introduced machine 15, gas storage Tank 16, internal combustion engine 17, generator 18, power supply line 20, photovoltaic and wind power generation plant 21, water purifying tank 22, water pump 23, washing Water pipe 24.

Condenser 1, compressor 2, evaporator 3, expansion valve 4, dry and cold intake stack 5, xeothermic wind pipe 6, pre-dryer 7, damp and hot wind pipe 8 constitutes predry drying system；Biomass processes and conveying equipment 10, gasification furnace 11, deduster 12, washer 13, drier 14, air-introduced machine 15, gas tank 16, internal combustion engine 17, generator 18 constitute gasification power generation system；Outlet pipe 9, Water warfare Pond 22, water pump 23, washing pipe 24 constitute water piping system.
