Embodiment Construction

[0019] The fluidized bed consists of three parts: the lower bed body 4, the middle enlarged section 5 and the upper enlarged section 6. The diameter of the middle enlarged section 5 is larger than that of the lower bed body 4, the diameter of the upper enlarged section 6 is larger than that of the middle enlarged section 5, and the upper enlarged section There is a cyclone separator 8 in the section 6, the top of the cyclone separator 8 is the syngas outlet 7, the bottom of the lower bed body 4 has a conical structure, and the jet tube is divided into the main jet feed tube 2 and the auxiliary jet tube 3, and the bottom of the lower bed body 4 is in a conical structure. The tapered structure at the bottom of the body 4 is equipped with an auxiliary jet tube 3 in two layers along the radial direction, and a main jet feed tube 2 is installed at the center of the bottom of the lower bed body 4 and on the same level as the auxiliary jet tube 3, and the lower bed body 4. The bottom ...

Abstract

The multi-jet composite fluidized bed coal and biomass gasifier consists of a fluidized bed, a synthesized gas outlet, a water vapor inlet and jet pipes. The fluidized bed consists of three parts, including the lower conic bed body, the middle expanding section and the upper expanding section, and has one cyclonic separator inside the upper expanding section. The synthesized gas outlet is in the top of the cyclonic separator. The jet pipes in the lower bed body include radial auxiliary material feeding jet pipes in two layers and main material feeding jet pipes in the center of bed body. The bed body has cinder outlet in the conic bottom and water vapor inlet beside the cinder outlet and the fluidized bed has outside heat insulating layer. The present invention has the advantages of simple structure, low cost and easy operation.

Description

technical field [0001] The invention relates to a gasification device for processing coal and biomass mixture, in particular to a multi-jet composite fluidized bed gasification device for preparing syngas by gasifying coal and biomass mixture. Background technique [0002] Coal is the fossil fuel with the largest reserves in my country. With the adjustment of the national energy structure, although the proportion of coal in energy consumption has declined, the total consumption of coal has shown an increasing trend year by year. At the same time, coal has caused serious pollution to the environment in the process of mining, transportation and use. As we all know, as a clean and efficient coal conversion technology, the industrial production of coal gasification has a history of nearly a hundred years. Especially in recent years, with the soaring international oil prices and the sharp increase in domestic demand for refined oil products, the mixture of carbon monoxide and h...
