Device and method for producing hydrogen by gasifying plastic biomass

Abstract

The invention discloses a device and a method for producing hydrogen by gasifying plastic biomass, and belongs to the technical field of chemical engineering and new energy utilization. The device comprises a mixing system and a cooling separation system, the mixing system comprises a melting part and a gasification part, the melting part comprises a melting chamber, the bottom of the melting chamber is provided with a feeding port, the gasification part comprises a fluidization chamber and an atomizer mounted at the top of the fluidization chamber, and the melting chamber is connected with the atomizer through a swing pump; the cooling separation system comprises a separation box and a cooling water jacket mounted outside the separation box; and a separator is connected to a pipeline between the fluidization chamber and the separation box. Waste plastic is melted and mixed with biomass particles to be atomized, then the mixture is fed into the fluidization chamber to prepare the hydrogen, and the hydrogen is purified after being cooled and separated. The device is energy-saving, environment-friendly, high in hydrogen production efficiency, low in power consumption and energy consumption and high in practicability.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and new energy utilization, and relates to a device for hydrogen production by gasification of plastic biomass and a method for hydrogen production by gasification. Background technique [0002] As a clean secondary energy source, hydrogen is increasingly used and applied. There are many kinds of hydrogen production technologies, which can be divided into three types according to the raw materials used: fossil fuel hydrogen production, renewable energy hydrogen production and water electrolysis hydrogen production. However, hydrogen production from fossil fuels has the disadvantages of high energy consumption and large amount of pollutant generation. Hydrogen production from water electrolysis accounts for about 4% of the world's hydrogen production, but consumes a lot of electricity. However, the use of solar thermal and high-temperature thermochemical water splitting to produce hydro...
