Abstract
The invention discloses an energy-saving and consumption-reduction biomass fuel machine-produced carbon rod and a production method thereof. The biomass fuel machine-produced carbon rod is formed through extruding 100 parts of by weight of a biomass fuel, 2-5 parts by weight of sodium humate, 1-3 parts of sodium carboxymethyl starch and 0.1-0.5 parts of sodium nitrate. The production method comprises the following steps: crushing the biomass fuel to 60 meshes or above; mixing and stirring the biomass fuel, sodium humate, sodium carboxymethyl starch and sodium nitrate in a stirrer until uniformity; and carrying out extrusion molding by adopting a screw feed rod maker to prepare the biomass fuel machine-produced carbon rod. The biomass fuel is bamboo dust, wood chips or crop straws, contains 15-30% of water, and can be directly used. Sodium humate and sodium carboxymethyl starch are introduced in the production technology of the biomass fuel machine-produced carbon rod as binders to substitute biomass colloids with a plasticizing effect, so the investment of a drying device is reduced, the energy consumption is reduced, and frequent maintenance or propeller replacement is avoided.
Description
Technical field
The present invention relates to biomass fuel mechanism carbon rod production technical field, especially energy-saving and cost-reducing biomass fuel mechanism carbon rod and production method thereof.
Background technology
By the biomass fuel mechanism carbon rod of bamboo bits, wood flour or crop straws for producing aftershaping, after carbonization kiln or carbide furnace carbonization, fixed carbon content is up to 60-85%, and caloric value is at 25-33MJ/kg.For replacing coal, waste resource can be made full use of, environmental pollution can be reduced again.
The production technology of existing biomass fuel mechanism carbon rod is:
A. biomass fuel is crushed to more than 60 orders；
B. within adopting roller drying machine to be dried to moisture content 12%；
C. adopt screwfeed formula bar-producing machine extruded；
D. adopt heating collar to dry in screwfeed formula bar-producing machine propeller front end.
The principle of the production technology of existing biomass fuel mechanism carbon rod is to utilize the vegetalitas colloid produced in screwfeed formula bar-producing machine extrusion process to plastify.Owing to bamboo bits, wood flour or agricultural crop straw moisture content are generally more than 30%, and the generation of vegetalitas colloid and plasticizing require that the moisture control of biomass fuel is within 12%.On the one hand, need to be dried raw material before extruded.It is reduced within 12% from moisture content more than 30%, not only needs the equipment such as investment buying roller drying machine, also can expend substantial amounts of energy.On the other hand, propeller works under 200-360 DEG C of high temperature and 70～100MPa condition of high voltage, biomass fuel coefficient of friction within moisture content 12% is big, the propeller adopting medium carbon steel manufacture is caused serious abrasion, cause that namely propeller needs after on average using 30-40 hour to repair or replace, dramatically increase production cost.And frequently repair or replace propeller and become the technical bottleneck restricting the production of existing biomass fuel mechanism carbon rod.
Summary of the invention
It is an object of the invention to provide one to reduce drying plant investment, reduce energy expenditure again without frequently repairing or replacing angle of rake biomass fuel mechanism carbon rod and production method thereof.
The technical scheme is that energy-saving and cost-reducing biomass fuel mechanism carbon rod and production method thereof, described biomass fuel mechanism carbon rod adopts following formula to be extruded from by weight:
Biomass fuel 100 parts,
Sodium humate 2-5 part,
Carboxymethyl starch sodium 1-3 part,
Sodium nitrate 0.1-0.5 part.
Described biomass fuel mechanism carbon rod adopts following steps to produce:
A. biomass fuel is crushed to more than 60 orders；
B. biomass fuel is adopted blender mixing and stirring with sodium humate sodium, carboxymethyl starch sodium and sodium nitrate；
C. adopt screwfeed formula bar-producing machine extruded, prepare biomass fuel mechanism carbon rod.
Described biomass fuel is bamboo bits, wood flour or agricultural crop straw, and moisture content rests in 15-30% and can directly use.
Described sodium humate is to join in reactor by the 100 parts of brown coal being crushed to more than 90 orders by weight, add the water of 200 parts, stirring while being warming up to 60-85 ° of C, adding 50 part of 35% sodium hydroxide solution and reacting 1-2 hour, prepare sodium humate after drying.
Described carboxymethyl starch sodium is to add clear water in a kettle., and heating, to 65-75 ° of C, is stirred and added starch, be subsequently adding sodium hydroxide and activate, add chloroacetic acid and carry out etherification reaction 5-6 hour；After reaction terminates, carry out washing, separate, dry, prepare carboxymethyl starch sodium；Producing carboxymethyl starch sodium formula by weight is: 100 parts of clear water, starch 25-40 part, sodium hydroxide 0.6-0.8 part, chloroacetic acid 1.3-1.6 part.
In such scheme, the moisture content of biomass fuel is generally more than 30%, can directly be used by natural drying, it is not necessary to the equipment such as investment buying roller drying machine, also saves substantial amounts of energy.
In such scheme, sodium humate system adopts the natural low magnesium brown coal of the low calcium of the high-quality containing humic acids to refine through chemical reaction and forms, it is the multi-functional macromolecular compound containing more active groups such as hydroxyl, quinonyl, carboxyls, there is very big internal surface area, have stronger absorption, exchange, complexation and sequestering power.On the one hand, the moisture that sodium humate and biomass fuel produce in extruded process forms glue, can reach good bond effect, replaces the plastication of vegetalitas colloid；On the other hand, sodium humate glue has excellent lubrication, can substantially reduce biomass fuel frictional force on propeller, significantly extends angle of rake service life, from without frequently carrying out angle of rake maintenance or replacing.
In such scheme, carboxymethyl starch sodium is a kind of anion starch ether, is dissolved in water and forms colloidal solution, to light, thermally-stabilised.Aqueous solution is more stable in alkali, poor in acid.There is the multiple performances such as thickening, suspension, dispersion, emulsifying, bonding, water conservation, protecting colloid.Mix use with sodium humate, tack and the cold strength of biomass fuel mechanism carbon rod can be improved.
In such scheme, sodium nitrate has oxidisability, heats to 380 DEG C and decomposes generation sodium nitrite and oxygen, releases nitrogen and oxygen when 600 1 600 DEG C.Owing to the biomass fuel mechanism carbon rod moisture content of the present invention is higher, carbonization time can be extended, by adding sodium nitrate, combustion-supporting smoke effect during carbonization can be significantly improved, both shortened carbonization time, reduce again environmental pollution.
Due to the fact that and introduce in the production technology of biomass fuel mechanism carbon rod and adopt sodium humate and carboxymethyl starch sodium as binding agent, replace the plastication of biomass colloid, thus drying plant investment can be reduced, reduce energy expenditure, again without frequently repairing or replacing propeller.
