Embodiment Construction

[0018] 1. Take charcoal powder or ash and crush it, and pass it through a 60-mesh sieve for later use.

[0019] 2. Take 50 parts of carbon powder, 20 parts of tar, 29 parts of waste water, and 1 part of naphthalenesulfonate, mix them evenly, put them into a wet grinder or a colloid mill for grinding, take samples to measure the powder size distribution, and discharge after meeting the requirements.

[0020] 3. Get 65 parts of ash, 5 parts of tar, 27 parts of waste water, and 3 parts of dodecylsulfonate. The same operation as in Example 2.

[0021] 4. Get 56 parts of ash, 13 parts of tar, 29 parts of waste water, and 2 parts of lignosulfonate. The operation is the same as in Example 2.

[0022] 5. Take 40 parts of charcoal powder, 20 parts of ash, 10 parts of tar, 28 parts of waste water, and 2 parts of lignosulfonate. The same operation as in Example 2.

[0023] 6. Get 35 parts of carbon powder, 23 parts of ash, 12 parts of tar, 25 parts of waste water, and 5 parts of lignosu...

Abstract

The invention relates to a sort of biomass slurry, wherein, waste residue, tar and waste water which are generated during energy transformation of biomasses such as crop straw and forestry wastes are mixed with emulsification dispersant to be made into the slurry through wet grinding; moreover, the weight percentage of the component is as follows: 50 to 65 percent of carbon powder or / and clinker,5 to 20 percent of tar, 20 to 40 percent of water and 0.5 to 5.0 percent of emulsification dispersant. The slurry has 63 to 68 percent of solid content, small particle diameter, good fluidity, less than 0.5 percent of 24-hour static bleeding rate and no obvious layering after 7-day standing; moreover, the slurry can replace coal water slurry to be used in gasification furnace and boiler.

Description

1. Technical field [0001] The present invention relates to a waste composition, in particular to a waste composition produced during biomass energy conversion, specifically a biomass slurry. 2. Background technology [0002] At present, various small-scale biomass gas supply stations built in rural areas in my country mostly use crop straw or forestry waste as raw materials, and use atmospheric pressure pyrolysis gasification or low-temperature dry distillation to perform low-efficiency energy conversion to prepare CO combustible gas with low calorific value. Large amounts of tar, waste water and charcoal (ash) which are difficult to utilize are produced. Not only a waste of resources, but also pollute the environment. 3. Contents of the invention [0003] The biomass slurry provided by the invention aims to comprehensively utilize the waste generated during the conversion of biomass energy to replace part of the coal-water slurry for gasifiers and boilers. The technical p...
