Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0031] The invention is mainly aimed at the research field of pyrolysis and combustion of certain materials, and particle flow, and particularly relates to the design method of biomass powder, coal powder, and particulate matter supply devices.

[0032] Take the experimental study of rapid and flash pyrolysis of biomass as an example: the heating rate in the pyrolysis reactor is fast, which requires small particle size and small amount of materials entering the furnace. Therefore, the continuous and stable feeding of the material supply device to the pyrolysis reaction zone plays an important role in the smooth progress of the pyrolysis experiment. At present, when scientific research units conduct pyrolysis reaction experiments on experimental platforms such as fixed bed reactors, f...

Abstract

The invention discloses an airflow portable type powdery material conveying device. The device comprises a discharging assembly, a conveying assembly and a vibrating assembly, wherein the dischargingassembly is installed at the top end of the conveying assembly, the discharging assembly is matched with the conveying assembly, the vibrating assembly is installed at the bottom end of the conveyingassembly, and the vibrating assembly is matched with the conveying assembly. According to the device, vibration exciting force generated when a vibration motor works is adopted to enable powdery materials to be in a flowing state, the materials are gathered into a bundle through a flowing path depend on self gravity and fall uniformly, gas is introduced to carry the powdery materials in the falling process to a discharge pipe of the device, the quantitative conveying of the materials is realized by changing the flow rate of the carried gas, and the device is particularly suitable for pyrolysisand combustion experiments of biomass and pulverized coal, and also suitable for related research of particle flow rules.

Description

Technical field [0001] The invention relates to the research field of pyrolysis and combustion of materials and particle flow, in particular to an airflow-carried powder material conveying device. Background technique [0002] The pyrolysis reactor is an important device in the pyrolysis process of graduate students. The commonly used pyrolysis reactors are mainly composed of: fixed bed reactor, fluidized bed reactor, moving bed reactor, etc. In addition, descending tube reactors and laminar flow furnaces independently designed by scientific research institutes are also important devices for studying the pyrolysis characteristics of solid fuels under rapid heating conditions. Because the material heating rate and thermal efficiency of the rapid pyrolysis reactor are relatively high, this puts higher requirements on the design of the material supply system of the pyrolysis reactor. For example, it is required that the particle size of the biomass material entering the reactor is ...
