specific Embodiment approach 1

[0017] Specific implementation mode one: a compound processing molding process of clean fuel lignite and biomass straw, which includes the following steps:

[0018] Step 1. The biomass straw is pulverized by a straw grinder for use; the biomass straw is a renewable variety of grain crop stems.

[0019] Step 2. After the clean fuel lignite is sieved by a sieving machine, it is sent to the crushing and mixing machine for crushing, and at the same time, the crushed biomass straw in step 1 is sent to the crushing and mixing machine for full mixing; the clean fuel lignite It can also be clean peat soil, which is a low-quality biomass fuel that has not been completely carbonized. It is a new biomass carbon raw material rich in high moisture, high volatile matter, high organic matter, and high humic acid with a low degree of deterioration. Its moisture content is 40 %-50%.

[0020] Step 3: Transport the uniformly stirred mixed material to a solidification molding machine, and extrud...

Abstract

The invention discloses a clean fuel lignite and biomass straw composite processing forming process, and belongs to the technical field of clean fuel composite processing. The problems that existing lignite and biomass straw are low in heat value, and the boiler output effect is not ideal when the lignite and the biomass straw are combusted independently are solved. The invention discloses a cleanfuel lignite and biomass straw composite processing and forming process. The process includes steps of: 1, crushing the biomass straw by a straw crusher for later use; 2, screening clean fuel lignitethrough a screening machine, sending the screened clean fuel lignite to a crushing and stirring all-in-one machine for crushing, and sending the biomass straw crushed in the step 1 to the crushing and stirring all-in-one machine for full stirring; 3, conveying the uniformly stirred mixture into a curing molding machine, and extruding the mixture into a cylindrical solid fuel. The solid fuel finished product processed by the process is small in size, easy to dehydrate through natural air drying to increase the heat value of the fuel, high in raw material utilization rate, free of black smoke emission after being combusted in a boiler, capable of filling the shortage of fossil coal and capable of being widely applied to industrial boilers, civil boilers and the like.

Description

technical field [0001] The invention relates to a composite processing molding process of clean fuel lignite and biomass straw, belonging to the technical field of clean fuel composite processing. Background technique [0002] At present, with global warming, lignite (peat soil) is a kind of biomass raw material that is not completely carbonized, and is a new type of biomass rich in high moisture, high volatile matter, high organic matter, high humic acid, and low degree of deterioration. Raw materials, renewable biomass straw has a huge annual output in China and is widely distributed. Due to the low calorific value of the moisture-rich material, it has been ignited and burned in farmland over the years, producing a large amount of smog and harmful gases, causing air pollution. . And the calorific value of above two kinds of raw materials is low, the boiler output effect when burning alone is unsatisfactory. Contents of the invention [0003] The invention aims to solve...
