Embodiment Construction
[0032] This embodiment provides a rotary kiln, such as figure 1 As shown, the bed material enters the rotatable inner cylinder 2 in the rotary kiln through the feed port 1, and is fully mixed with the gasifying agent entering from the gas distribution port 3 to be gasified, and then discharged from the outlet 4 at the tail. This rotary kiln device has optimized the gas distribution system of the traditional rotary kiln, that is, the entry path of the gasification agent. The gasification agent can enter along a fixed position and direction, and the air intake is controllable. The following will be further explained in conjunction with the device The method of realizing its technical effect.
[0033] The air distribution system of the rotary kiln provided in this embodiment includes the following components: an air inlet pipe 6 , an air storage device 5 , an air inlet 7 , an air chamber connecting pipe 8 , an air chamber 9 , an air distribution pipe 10 , and an air distribution ...

The invention discloses a gas distribution system of a rotary kiln. Through the gas distribution system, a fixed gas storage device cooperates with a rotary gas inlet to control a gas distribution angle; a fluid conveying device matched with the gas inlet and a gas cavity capable of controlling gas intake amount of each gas distribution pipe are used, so that the requirement on fine gas distribution is met; in addition, in order to improve the sealing performance of the device, a matched position between a rotary part and a fixed part is sealed by a flexible device, so that the problem of poorgas tightness of the conventional rotary kiln gasifier is solved.
Description
technical field [0001] The invention relates to the field of design and manufacture of a rotary kiln, in particular to a gas distribution system of a rotary kiln. Background technique [0002] The rotary kiln can be used in industries similar to cement, lime, and hazardous waste treatment. The fuel enters the slowly rotating kiln from the upstream end, and the gasification agent is added along the way. When the fuel moves along the length of the kiln, the rotation promotes the fuel and The gasifying agents are mixed and gasified. The many advantages of the rotary kiln are especially suitable for the treatment of biomass, hazardous waste, municipal waste, etc., and are especially suitable for distributed energy. A lot of work has been done on the mixing of raw materials and gas phase to achieve deep gasification, and it is expected to find a more efficient, controllable, predictable and highly reliable gas distribution solution. [0003] Representative ones are Callidus Rot...
