[0016] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0017] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0018] like Figure 1-2 As shown:

[0019] The utility model provides a gasification agent normal pressure delivery device, comprising a hollow annular groove 1 with a circular inner circle, seal heads are arranged at both ends of the annular groove 1, radially extending hollow groove-shaped cylinders 2 are evenly arranged on the inner side surface of the annular groove, the interior of the annular groove 1 is connected with the groove-shaped cylinder 2, and the seal head at one end of the annular groove 1 is provided with an opening.

[0020] Specifically, the inner side surface of the annular groove 1 of the present scheme is evenly spaced with radially extending hollow groove-shaped cylinders 2, and the interior of the annular groove 1 is connected to the groove-shaped cylinder 2. When in use, the gasifying agent normal pressure delivery device embraces the periphery of the gasifier, and the groove-shaped cylinders 2 evenly arranged on the inner periphery are inserted into the entry tubes evenly arranged on the outer periphery of the gasifier. The gasifying agent is fed into the annular groove 1 from the end opening of the annular groove 1, and is diverted into the gasifier through the evenly arranged groove-shaped cylinders 2, so that the flow rate and flow velocity of the gasifying agent entering the gasifier are consistent, ensuring the continuous and stable thermal conditions of the fuel in the furnace to generate biomass gas and biomass charcoal.

[0021] As an optional implementation, the cross-sectional dimension of one end of the annular groove opening is larger than the cross-sectional dimension of the other end thereof.

[0022] As an optional implementation, the cross-sectional size of the annular groove 1 gradually decreases from one end with the opening to the other end.

[0023] Specifically, the cross-sectional size of the annular groove 1 gradually decreases from one end with an opening to the other end. This structure, which is wide at the beginning and narrow at the end, combined with the grooved cylinders 2 evenly spaced along the inner circumference normal of the annular groove 1, allows the gasifying agent to be evenly distributed through the annular groove 1 from the opening through the grooved cylinders 2 with equal spacing. That is, the gasifying agent is released into the furnace cavity with a consistent flow rate and velocity under the action of the blower connected to the front end of the opening of the gasifying agent normal pressure delivery device, thereby performing a thermochemical reaction on the biomass fuel.

[0024] As an optional embodiment, the distance between the two end caps of the annular groove 1 is smaller than the distance between two adjacent grooved barrels 2. Therefore, the grooved barrels 2 can be arranged corresponding to the inlet pipes arranged at equal intervals on the periphery of the gasifier, so that the gasifying agent can be evenly distributed through the grooved barrels 2 and enter the gasifier.

[0025] As an optional implementation, the opening is connected with an elbow 3 and a straight pipe 4. An external blower is connected through the elbow 3 and the straight pipe 4 to transport the gasification agent. Generally, 4 to 5 cubic meters of air are required for a thermochemical reaction of 1 kg of biomass fuel, and the oxygen content of the air is 20.95%. The air as a gasification agent comes from the blower, and the blower sends the air into the gasification agent normal pressure delivery cylinder, and the air pressure is balanced in the cavity of the gasification agent normal pressure delivery cylinder, which is wide at the beginning and narrow at the end.

[0026] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
