Embodiment 1

[0045] Embodiment 1: refer to each accompanying drawing.

[0046] A biomass pyrolysis gasification and purification method mainly consists of the following steps:

[0047] (1) Crush biomass: remove biomass (which can be one or more mixtures of wheat straw, straw, corn stalk, rape stalk, reed, rattan, bamboo, herbs or other cellulose-containing materials ) in soil impurities, dry the water until the water content is not more than 20%, then pulverize the biomass through a pulverizer, and leak out through a sieve with an aperture of 3-15mm in the pulverizer;

[0048] (2) Furnace gasification: The pulverized biomass is fed intermittently into the two-stage straw gasification generator, and the gasification agent air-water vapor or water vapor-oxygen is sent to the two-stage straw gasification In the middle gasification section of the producer, the producer gas is produced by the pyrolysis reaction between the two at 800-1000°C;

[0049] The specific process is: after the crushed...

Embodiment 2

[0064] Embodiment 2: refer to each accompanying drawing.

[0065] A biomass pyrolysis gasification and purification method mainly consists of the following steps:

[0066](1) Grinding biomass into shape: removing biomass (which can be one or more of wheat straw, rice straw, corn stalk, rape stalk, reed, rattan, bamboo, herbs or other cellulose-containing materials) the soil impurities in the mixture), dry the water until the water content is not more than 20%, then pulverize the biomass through a pulverizer, and leak out through a sieve with an aperture of 3-15mm in the pulverizer;

[0067] Then the crushed biomass is extruded into granules by a pellet press; the extruded granules can be cylinders with a diameter of 3-50mm and a length of 4-80mm or similar shapes, or a side length of 4-80mm cuboid, cube or similar shape.

[0068] (2) Furnace gasification: The formed biomass is intermittently fed into the two-stage straw gasification generator, and the gasification agent air-...

Abstract

The invention provides a biological mass thermal decomposition, gasification and purification method which comprises, disintegrating the biological mass, gasifying in a furnace, obtaining retort gas, cyclone dedusting, cooling down and purifying, high voltage static coke trapping, making the coke tar bubbles and dust in the coal gas deposit onto the coke collection poles, thus purifying the coal gas, finally washing and dewatering.

Description

technical field [0001] The invention relates to dry distillation and gas purification of cellulose-containing materials, in particular to a biomass pyrolysis gasification and purification method. Background technique [0002] With the progress and development of society, human beings' requirements for various energy sources are increasing day by day. The most commonly used non-renewable resources such as petroleum, coal, and natural gas, have caused a sharp decline in reserves due to large-scale exploitation and use, which has constituted one of the three major crises (energy shortage, food shortage, and environmental pollution) for human survival and development today. one. Therefore, the development of energy and energy conservation have become the focus of great attention of governments and people of insight in the world today. [0003] my country is a large agricultural country with a large population and relatively few resources. On the one hand, with the rapid devel...
