[0016] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] The following is combined with Figure 1-3 The utility model is further described as follows:
[0018] A biomass heat exchange drying furnace comprises an outer shell 11, a furnace body 3 and a heat exchange device are arranged inside the outer shell 11, a biomass silo 1 is arranged outside the outer shell 11, a discharge pipe below the biomass silo 1 is connected with the middle and lower part of the furnace body 3, a burner 2 is arranged on the discharge pipe below the biomass silo 1, a fire viewing port 5 connected with the middle part of the furnace body 3 is opened on the outer shell 11, a slag removal port 4 connected with the lower part of the furnace body 3 is opened on the outer shell 11, and an insulation layer 12 is arranged outside the outer shell 11.
[0019] In this embodiment, preferably, the furnace body 3 is made of steel plate rolls, the burner 2 helps to fully burn the biomass fuel, the fire viewing port 5 is convenient for observing the fire in the furnace body 3, the slag removal port 4 is convenient for cleaning the residue in the furnace body 3, and the insulation layer 12 can effectively reduce the heat loss inside the outer shell 11.
[0020] The heat exchange device includes a flue 6, which is arranged in a zigzag shape up and down inside the shell 11. A smoke outlet 13 is arranged on the upper part of the side wall of the furnace body 3. One end of the flue 6 is connected to the smoke outlet 13, and the other end of the flue 6 is connected to a smoke induced fan 7 arranged above the outside of the shell 11. An air duct 10 is formed between the shell 11 and the flue 6. An air inlet 8 is opened at the lower part of the shell 11 away from the furnace body 3, and a blower 14 is arranged at the air inlet 8. An air outlet 9 is opened at the upper part of the shell 11 close to the furnace body 3.
