Problems solved by technology

For the rotary furnace type, there is a high requirement for the dryness of the material and the lack of sealing is difficult; while for the spiral propulsion type, because the spiral body fills the entire carbonization tube, it is in close con

Embodiment Construction

[0018] The application of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] refer to figure 1 , a semi-helical inclined continuous carbonization conveying device, which includes a pusher system and a collection system arranged in dislocation, the pusher system is located above the collection system, and a tubular heated carbonization system is installed between the pusher system and the collection system, The heated carbonization system is placed obliquely and connected to the pusher system and the collection system.

[0020] In the present invention, the pusher system and the collection system arranged in a dislocation of the heated carbonization system are placed obliquely, so that the pusher system and the heated carbonization system are separated. During carbonization, after installing the heater under the heated carbonization system or placing it on the heating furnace, To heat the heated carbonization system,...

Abstract

A disclosed semi-spiral oblique continuous-charring material-conveying apparatus comprises a material-pushing system and a collecting system which are disposed in a staggered way; the material-pushing system is disposed above the collecting system; and a tubular heating charring system is obliquely disposed between the material-pushing system and the collecting system, and is communicated with the material-pushing system and the collecting system. By connecting the obliquely-disposed heating charring system with the material-pushing system and the collecting system which are disposed in a stagger way, the material-pushing system and the heating charring system are separated; when charring, the heating charring system is provided with a heater below the heating charring system or is placed on a heating oven, and the heating charring system is heated while the material-pushing system is at normal temperature, so that the material-pushing system is avoided working at a high-temperature environment, and the apparatus is improved in service life and enhanced in adaptability; and also because the heating charring system is obliquely disposed, materials in the heating charring system moves under the effects of self gravity and thrust from the material-pushing system, so that the materials are conveyed continuously, and extrusion between the materials and the heating charring system does not exist basically.

Description

technical field [0001] The invention belongs to the field of sludge treatment, and in particular relates to a semi-helical inclined continuous carbonization conveying device used in sludge carbonization equipment. Background technique [0002] Sludge carbonization is a process in which dry sludge is heated at high temperature in an oxygen-free (anoxic) environment, and organic matter is converted into water vapor, non-condensable gas and charcoal under the action of dry distillation and pyrolysis. Carbonization is similar to incineration, both of which are heat treatment methods, and are both a thorough sludge treatment technology; however, compared with incineration, carbonization products have multiple uses, and they are more superior in terms of energy consumption, pollutant discharge and product resource utilization. There are advantages in terms of utilization. Therefore, sludge carbonization has been considered as a sludge heat treatment method with broad application ...
