Abstract

The invention discloses normal-pressure superheated steam using carbonization and pyrolysis equipment. The normal-pressure superheated steam using carbonization and pyrolysis equipment comprises a carbonization reactor, wherein a first gas inlet for injecting superheated steam and a first gas outlet for discharging the steam are formed in the carbonization reactor; the first gas inlet is communicated with a gas inlet pipeline; the first gas outlet is communicated with a gas outlet pipeline; a superheated steam generation mechanism is arranged between the first gas inlet and the first gas outlet; the superheated steam generation mechanism comprises a first heat exchanger with a gas outlet communicated with the gas inlet pipeline, a reheating electromagnetic coil arranged on the gas inlet pipeline and a steam generator with a gas outlet communicated with a gas inlet of the first heat exchanger; the first heat exchanger is arranged on the gas outlet pipeline. On one hand, the normal-pressure superheated steam using carbonization and pyrolysis equipment can work and operate at a normal pressure, so that the cost of purchasing the equipment is reduced; on the other hand, the waste heatof exhaust gas can be recycled, so that the aims of saving energy and reducing consumption are fulfilled.

Description

Technical field [0001] The present invention relates to the technical field of carbonization cracking equipment, in particular to a carbonization and cracking equipment using normal pressure superheated steam. Background technique [0002] The carbonization and cracking technology of biomass and industrial scraps is an important direction for resource recycling. However, the current carbonization and cracking equipment cannot recycle the waste heat of exhaust gas, and the carbonization and cracking is carried out under high pressure, which affects the performance of the equipment. The requirements are relatively high. Therefore, it is necessary to develop a new equipment for carbonization and cracking. [0003] The invention application with publication number CN 104232124B discloses a biomass pyrolysis carbonization and gasification device, including a pulverizer, a dryer, a forming machine, a cracking device, a first water sealing tank, a rough purifier, and an acid Washing tan...
