Problems solved by technology

The biggest advantage of this system is that the pyrolysis product can quickly leave the reactor under vacuum, thereby reducing the probability of secondary reactions, but it needs the normal operation of the vacuum pump and the excellent sealing of the reactor to ensure, and this is in practical application. It will increase the investment cost and operation difficulty

Embodiment Construction

[0014] Below in conjunction with accompanying drawing, the present invention is described in detail: in actual design and manufacture, the present invention is to enter self-mixing fluidized-bed descending reactor (5) through conveying by screw conveyer (10) through the solid organic matter after the drying pulverization Inlet, contact, mix and react with the high-temperature regeneration agent entering from another inlet in the self-mixing downward fluidized bed reactor (5), and leave the reaction section quickly; the gas phase passes through the self-mixing downward fluidized bed reactor (5) The outlet of the gaseous phase enters the quench cooler (6) to condense and separate into pyrolysis oil and pyrolysis gas, which are separated by the oil tank (15), and part of the pyrolysis oil is pumped back to the water cooler (17) by the liquid circulation pump (16) to cool and then made It is the cooling source of the quench cooler (6); the solid phase enters the fluidized bed regen...

Abstract

The invention provides a solid organic matter self-mixing descending fluidized bed fast thermolysis technique. A reaction regeneration cycle system is formed by leading fast thermolysis and scorch to be carried out in different systems and circularly coupling solid heat carriers, thus ensuring pyrolytic reaction to be carried out continuously and the regenerated heat to be reasonably utilized; furthermore, pyrolytic gas and oil with high quality can be produced, so that the resource utilization rate is improved. The invention mainly comprises a self-mixing descending reactor, a fluidized bed reactivator, etc.

Description

1. Technical field [0001] The invention provides a fast pyrolysis process of solid organic matter in a self-mixing downward fluidized bed, which belongs to the field of renewable energy. 2. Background technology [0002] With the improvement of people's living standards and quality, the content of organic matter in urban waste is gradually increasing, and landfill treatment can no longer meet the requirements of environmental protection. Incineration reduction treatment will not produce harmful substances such as dioxins, and it is safe and economical to dispose of urban waste. Garbage is known as a hot spot for people to research and explore; rural plant straw is a renewable resource, and there is already a technology for comprehensive utilization of its gasification and gas production, but since pyrolysis and aerobic combustion are completed in the same system, the calorific value of pyrolysis gas Low, only 4000 kcal / m3, improving the quality of pyrolysis gas is a research...
