Pyrolysis and dry distillation system

Abstract

The present invention provides a pyrolysis and dry distillation system. The pyrolysis and dry distillation system comprises a reaction kettle barrel, wherein an exhaust port and a feed port are formedin the upper part of the reaction kettle barrel, a discharge port is formed in the lower part of the reaction kettle barrel, a rotating shaft is arranged in the reaction kettle barrel, a spiral bladeis arranged at one end, close to the feed port, of the rotating shaft, and special-shaped stirring blades are arranged at the other parts of the rotating shaft at intervals and are staggered up and down in the axial direction of the rotating shaft at intervals. The pyrolysis and dry distillation system is not prone to material blockage, sufficient in pyrolysis and dry distillation reaction and high in resource recycling rate.

Description

technical field [0001] The present invention relates to dry distillation dedicated to specific solid raw materials or special forms of solid raw materials, in particular to a pyrolysis dry distillation system. Background technique [0002] my country is a large agricultural country, which produces a large amount of straw, bamboo and wood waste, grain husks and other biological waste every year. The effective utilization rate of these wastes is very low, and most of them are burned, which not only pollutes the environment but also wastes resources. To solve this problem, as figure 1 As shown, the Chinese invention patent application with the publication number CN 105087030 A provides a pretreatment biomass multifunctional gasification integrated machine, the auxiliary machine includes an auxiliary machine conical screw propulsion drive shaft 1', hopper 2', auxiliary machine Conical material cylinder 5' of the machine, and the auxiliary machine conical material cylinder 5' is...

Problems solved by technology

However, the auxiliary machine of the device is a linear body as a whole, and the material can fall freely under the action of its own gravity, and the falling speed is relatively fast. On this premise, the work of the auxiliary machine conical screw propulsion drive shaft 1' makes the material fall faster. , which makes it very easy to block the connection between the main machine and the auxiliary machine

Moreover, the whole body of the screw propulsion drive shaft 7' of the main engine is a helical blade, and the helical blade has a good stirring effect along the circumferential direction of the main engine, but the effect of pushing the material along the axial direction of the main engine is not ideal. Therefore, during the rotation of the main engine drive shaft, the material along the drive shaft The upper and lower positions in the radial direction are basically fixed, and it is difficult to move axially along the drive shaft. Materials often accumulate between adjacent blades, which not only leads to serious material blockage in the main engine, but also affects the reaction effect of materials in the main engine.
