Rapid pyrolysis reactor

Abstract

The invention provides a rapid pyrolysis reactor. The rapid pyrolysis reactor comprises heat storage type radiant tubes and a stirring device. The multiple layers of the heat storage type radiant tubes are arranged inside the rapid pyrolysis reactor in the length direction of the pyrolysis reactor, and multiple heat storage type radiant tubes parallel to one another in the horizontal direction are arranged on each layer. The stirring device comprises a stirring shaft and multiple stirring rods connected to the stirring shaft. The stirring shaft rotationally stretches into the reactor from a semi-coke outlet. By means of the rapid pyrolysis reactor, pyrolysis efficiency can be remarkably improved, and the yield of pyrolysis oil can be increased.

Description

technical field [0001] The invention belongs to the field of chemical industry, in particular, the invention relates to a fast pyrolysis reactor. Background technique [0002] Natural gas is a very precious resource due to its clean and environmentally friendly performance. my country's energy structure is characterized by "more coal, less oil, and less gas". Therefore, the production of oil and gas from fossil fuels is the way out to solve my country's energy problems. The process of coal-to-gas is complex, the scale of investment is large, and the consumption of water resources is large, which has become a bottleneck restricting the development of coal-to-gas. Coal low-temperature dry distillation, the products can be comprehensively utilized (oil, gas, semi-coke), which can not only increase the added value, increase economic benefits, but also reduce environmental pollution caused by coal burning. It is considered to be an effective way for efficient and clean utilizatio...

AI Technical Summary

Problems solved by technology

The oil yield of some furnace types is low, and the gas is used as the heating carrier, resulting in a huge condensation recovery system, the pyrolysis and retort gas is diluted, the calorific value of the gas is low, and it is difficult to further comprehensively utilize other problems; the pyrolysis of some solid heat carriers For the furnace type, there are processes such as mixing of raw materials and heat carrier, and reheating and back mixing of heat carrier. The process is more complicated, the equipment is more, and the manufacturing cost and operating cost are high.

In addition, in the existing industrial pyrolysis process, the purpose is to produce a large amount of tar, the output of pyrolysis gas is small, or the pyrolysis gas is burned and utilized by the subsequent cycle process, and what is more harmful to coal pyrolysis gas production and Not enough oil
