Description

A kind of low cost, the straw biomass rod and preparation method thereof of desulfurization

Technical field

The present invention relates to a kind of composite solid fuel and preparation method thereof, particularly relate to the straw of a kind of low cost, desulfurization Biomass combustion rod and preparation method thereof.

Background technology

The production of biomass granule fuel starts from the thirties in 20th century, but is the oil crisis in the seventies as industry Period grows up.Owing to oil price rose violently at that time, the fossil energies such as coal, oil, natural gas are used to lead the most in a large number The problem such as petroleum resources atrophy and global warming of cause, forces continent country of part Europe, the United States Devoting Major Efforts To Developing and utilizes alternative energy source. Active development and the reproducible clean energy resource of use, the consumption of minimizing fossil energy, the discharge of reduction greenhouse gases, it has also become generation Various countries of boundary alleviating energy crisis and the common recognition of weather variation issue.Now biomass granule fuel is through the development of decades, raw Product technology is gradually grown up, and product quality is greatly improved.Give up owing to its raw materials for production are mainly derived from local forestry Gurry, cost of transportation is low, low price, so inexpensive biomass granule fuel becomes the replacement energy of coal and natural gas Source.

Zhao Peitao utilize in " mud and straw biomass solid fuel prepare pilot process and combustion characteristics " mud and The biomass such as mud and straw are prepared for a kind of solid fuel, but this solid fuel is solid cylinder, burned Journey also exists calorific capacity is little, nonflammable, burning is thorough, thus gives off substantial amounts of harmful gas, be unfavorable for environmental protection.

Summary of the invention

Based on above thinking, it is an object of the invention to provide formula and the preparation side of a kind of biomass solid fuel Method, solves that the calorific capacity that current biomass solid fuel exists is little, nonflammable, burning is thorough, pollute the problems such as environment.

For achieving the above object, technical scheme is as follows:

A kind of low cost, the straw biomass rod of desulfurization, it is characterised in that be made up of the raw material of following weight portion:

Colophonium 1-2, mud 5-10, yeast 1-2, cattle manure 2-4, coal dust 5-10, polyvinyl alcohol 2-3, paraffin 3-6, yellow mud 10-20, Straw 10-20, lignin 1-3, rice straw 5-10, bamboo wood material 5-10, branch 3-5, iron sesquioxide 4-8, zirconium dioxide 0.1- 0.4, water is appropriate；

Described sludge moisture content is 30-50%, and yellow mud water content is 50-70%, coal dust calorific capacity >=5000 kilocalorie, particle diameter≤5mm.

Described a kind of low cost, straw biomass rod of desulfurization and preparation method thereof, it is characterised in that described combustion Burning rod uses profile to be circular hollow-core construction.

Described a kind of low cost, straw biomass rod of desulfurization and preparation method thereof, it is characterised in that be by with Lower step is made:

A. coal dust is uniform with polyvinyl alcohol, put into drying oven after making compound, under the conditions of 60 DEG C-80 DEG C, dry 4- 5 hours, to moisture≤5%, sending into low temperature distillation stove, under the conditions of 600 DEG C-900 DEG C, dry distilling is come out of the stove for 2-6 hour, obtains nothing Cigarette lump coal；

B., after straw, rice straw, cattle manure being pulverized the particle for 3-6mm by polisher, it is placed in the environment that temperature is 30-40 DEG C In to be baked to moisture be 30-50%, then yeast wherein, under 45-75 DEG C of environment, store up fermentation process 10-20 days, Fermented product；

C. bamboo wood material, branch are cut into by shear the coarse fodder of 8-12mm, then are the broken of 3-6mm by polisher pulverizing Material, adds step b gained fermented product, lignin and mud, stirs, and at 30-50 DEG C after stacking 2-5h, uses biology Carbon low-temperature carbonization technology, carries out carbonization by this mixture under the conditions of carburizing temperature 200-300 DEG C and oxygen barrier, pulverizes, through screening The particle diameter carbide at below 5mm chosen by machine；

D. in yellow mud, add step a gained anthracite block coal, step c gained carbide, ferrum oxide, zirconium dioxide and paraffin, add Water is configured to the mixture that water content is 60-80%, forwards in rod-pressing machine by mixture, squeeze with rod-pressing machine after stirring 10-20 min Be pressed into rod, be dried after taking-up to water content be 10-20%.

The invention has the beneficial effects as follows: by the addition of stalk fermentation thing so that bamboo wood and branch, under sugar effect, are sent out Raw a certain degree of microcosmic effect so that it is during extruded, it is possible to form fine and close granule, it is to avoid biomass fuel The laxity of material, extends the burning time of the biomass fuel of Unit Weight；Iron sesquioxide, the addition of zirconium dioxide, have The discharge decreasing the toxic gas such as sulfur dioxide of effect, beneficially environmental protection and the mankind healthy；By dirt in carbonisation Mud is carbonization together with straw, branch etc., is possible not only to utilization and the part heavy metal ion contained in mud is deposited in lime-ash, Alleviate environmental pollution, the mobility of mud and lubricity can be utilized again to promote the fusion between each raw material and bonding, be conducive to The molding of fuel.The addition of paraffin promotes the abundant burning of fuel, makes fuel be prone to light；Coordinate the cattle manure etc. added, fall The low production cost of finished product.

Detailed description of the invention

Below in conjunction with embodiment, the detailed description of the invention of the present invention is further described.
