NOVELTY - A biomass energy is used by crushing biomass raw material, gasifying into reaction furnace, thermochemically reacting at 1200 degrees C, cooling at maintained temperature of 1000 degrees C to obtain high temperature wood gas and carbon dioxide gas, entering carbon dioxide gas into carbonization furnace through fugitive emission and direct contact with wood, entering wood gas into carbonization furnace through metal radiating pipeline and without direct contact with wood, calcining, entering carbon dioxide gas and wood gas into water treatment system through metal radiating pipeline, cooling, and storing.    USE - Use of biomass energy for circulating coolant (claimed) and crop fertilizer.    ADVANTAGE - Process is simple, reduces energy cost, and has no waste emission.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for water treatment system comprising sealed insulating water tank, 2 sets of water system, and 2 sets of sleeve water system in which sealed insulating water tank is filled with cold water, bottom is set with 2 flat metal frame vent pipes and connected with wood gas pipe and carbon dioxide gas pipe, densely flat metal frame vent pipe is soaked in cold water of sealed insulating water tank bottom, vent pipe is discharged from water tank and stored, water tank is set with water inlet pipe and water outlet pipe, cold water is from bottom of water inlet pipe, hot water is from top of water outlet pipe, water tank is set with internal temperature indicator probe, 2 sets of water system, 1 set of warm water system comprising long warm water pipe, and other set of solar water system are introduced into underground pipe, long warm water pipe is connected with water inlet pipe of water tank, solar water system comprises solar water tank and pipeline, water inlet pipe from bottom of solar water tank is connected with tap water, water outlet pipe from top of solar water tank is reversely rotated with water inlet pipe of water tank, outflow hot water from 2 sets of sleeve water system and 1 set of used hot water is automatically replenished by solar water or warm water, cold water is continuously heated through wood gas and carbon dioxide, other set of air conditioner is used to heat and cool during winter and summer, water outlet pipe is set with bypass pipe during winter, bypass pipe is connected with radiator interior, radiator is set with water outlet pipe, water outlet pipe is connected with reflux pipe, all water outlet pipes of radiator are entered into reflux pipe and radiated again after cooling water tank, warm water does not enter into water tank to heat water during summer, ground water pipe is connected with indoor radiator through distributing pipe, and reflux pipe of radiator is connected with distributing pipe through reflux pipe and entered into temperature tube of water inlet pipe.
