AI Technical Summary

Problems solved by technology

Moreover, the high-temperature oil-gas circulation fan has high investment costs and poor on-site use effect
In addition, in the radiation heating process, because the radiant tube has a certain distance from the material, usually between 500mm-1200mm, the heat conduction rate is significantly reduced, the temperature gradient between the material layers is significantly increased, and the pyrolysis uniformity is poor.

Embodiment Construction

[0020] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:

[0021] Depend on Figure 1 to Figure 3 It can be seen from the preferred specific embodiments of the present invention shown that before the material enters the dry distillation furnace, it needs to be pretreated,

[0022] This preprocessing includes one or more of the following:

[0023] a) Raw material crushing: crush the above raw materials according to the requirements of pyrolysis until the particle size is less than 100mm.

[0024] b) Drying of raw materials: Dry the crushed raw materials according to the pyrolysis requirements, and the drying temperature is 30°C-220°C.

[0025] After the material is pretreated, it is fed into the inlet bin of the distribution plate through the upper feed port of the rotary retort furnace. Under the action of the distribution baffle, the material is uniformly distributed on the distribution plate, and the thic...

Abstract

A novel rotary gas retort is disclosed. The rotary gas retort comprises a middle-temperature flue gas generator, a hearth (2), a material distributing plate (3), a middle-temperature flue gas heating zone (4), a flue gas insulating plate (10), an upper dynamic sealing ring (13), a lower upper dynamic sealing ring (12), a middle-temperature flue gas feeding pipeline (8), a middle-temperature flue gas inlet (A), a low-temperature flue gas discharging pipeline (14), a low-temperature flue gas outlet (B), a material inlet, driving wheels (7) and an induced draft fan. The middle-temperature flue gas generator can be a heat accumulating type middle-temperature flue gas generator. The novel rotary gas retort has advantages of uniform heating for materials, low investment cost, high heat efficiency, good retorting effects, simple equipment operation, safe and reliable running, and the like.

Description

technical field [0001] The invention relates to the field of dry distillation and provides a novel rotary dry distillation furnace. Background technique [0002] Dry distillation technology is a process in which materials are heated and decomposed under air-isolated conditions to produce coke (or semi-coke), tar, solution, dry distillation gas and other products. Dry distillation technology has been widely used in the utilization and development of conventional resources, waste treatment and the development of new energy, especially bio-energy. There are many methods and types of dry distillation. According to the heating method, there are external heat type, internal heat type and internal and external heat combination type; according to the shape of the material, there are three types: block material, type material and powder material; There are two types of carrier and solid heat carrier; according to the moving state of the material, it is divided into fixed bed, moving...
