Disclosed is a biomass energy burner, which comprises a combustion chamber (11) with a material charging inlet (13) and a charcoal discharging outlet (16). A charcoal discharging auger (15) is disposed at the charcoal discharging outlet (16), and the pitch of the spiral blade of the charcoal discharging auger (15) is gradually reduced along the charcoal discharging direction. The burner can discharge charcoal while material is burning, so that the material does not completely bum into ash in the combustion chamber (11). The burner can also compress combustion substrate while discharging charcoal and further carbonize the combustion substrate to increase carbon content of the final product. Moreover, the combustion chamber (11) in-takes air at multiple angles via main air inlets (18) and air distribution holes (19), thereby changing the airflow direction in the combustion chamber (11), increasing the contact time and contact surface of combustion-supporting air and combusting material, and improving combustion-supporting effect. Additionally, the combustion-supporting air is preheated for multiple times by the heat of the combustion chamber (11), which reasonably utilizes heat and reduces heat loss.

The invention belongs to the field of radiator device equipment, and particularly discloses a forced convection device for a tube-and-fin radiator. The device consists of fins, heat pipes and guide rudders; a plurality of forming holes are punched in parallel fins according to the position structures of the heat pipes, so that the heat pipes are arranged in the forming holes in a sleeving manner for fixing; the guide rudders are symmetrically and fixedly mounted on the two side walls of each heat pipe; the guide rudders are low-resistance aircraft airfoil profiles and are mounted at certain angles; the sum of the mounting angles of the two symmetrical guide rudders on the two sides of each heat pipe is 360 degrees; air among the fins can form two air helixes which are parallel to each other and are in the same rotating direction in the vertical direction; forced convection is formed at the tangent part of the two air helixes. According to the forced convection device disclosed by the invention, a heat exchange effect of wall surfaces of the heat pipes as well as the fins and the air is strengthened on the basis of ensuring normal flow of the air; meanwhile, the rotating of the air in flow channels is realized through the mounting directions, so that the air in adjacent two flow channels rotates in the same direction, forced air convection is realized, and the radiator can adapt to the change of a variety of conditions.

A wall-mounted air conditioner indoor unit, comprising: a housing (100) having an air outlet (120) at the front side bottom portion, a flow guide plate (200) provided below the housing (100) and forming an air mixing duct (130) with the bottom surface of the housing (100), the indoor air flowing to the air outlet (120) through the air mixing duct and being mixed with the air from the air outlet (120); a lead screw (300) which is parallel to the lengthwise direction of the housing (100) and rotatably mounted to the housing (100) and has at least one threaded section group (320), each threaded section group (320) comprising a left threaded section (322) and a right threaded section (321); a first motor (310) used for driving the lead screw (300) to rotate; at least one bracket assembly (301) comprising two ball sliding blocks (350) which are mounted to the left threaded section (322) and the right threaded section (321) respectively; two upper rods (330), the upper ends of the two upper rods being hinged to the two ball sliding blocks respectively; and a lower rod (340), the upper end of the lower rod being hinged to the lower ends of the two upper rods (330), and the lower end of the lower rod being connected to the flow guide plate (200). When the lead screw (300) rotates in a positive direction or in a reverse direction, the upper ends of the two upper rods (330) are driven, by the two ball sliding blocks (350), to translate toward each other or away from each other, such that the lower rod (340) is driven to translate up and down by the two upper rods (330), the flow guide plate (200) is driven to translate up and down, and thus the overflow area of the air mixing duct (130) is changed.

The invention relates to a guide blade or a stator blade, and an air treatment device having the guide blade or the stator blade. The guide blade or the stator blade comprises a wheel hub, blades and a wheel cover, wherein the blades are distributed on the wheel hub and / or the wheel cover at certain intervals along the circumferential direction. Structural characteristics of the guide blade or the stator blade are that: the blades comprise a first group of blades and a second groups of blades; the two groups of the blades have conductive properties; the first group of the blades and the second group of the blades are staggeredly distributed and insulated, and are not conducted; the first group of the blades and the second group of the blades are respectively applied with high potential and low potential so as to form a charged high voltage space between the first group of the blades and the second group of the blades, the high voltage space forms a dust removing channel, and the dust removing channel can effectively adsorb dust particles flowing through the dust removing channel. The blade and the device of the present invention have characteristics of simple and reasonable structure, high dust absorption efficiency, low resistance, low power consumption, low noise and no pressure loss. In addition, with the blade and the device of the present invention, air delivery, air pressure and efficiency of a fan can be effectively improved.
