Abstract
The invention discloses a straw solidified carbon rod and a processing method thereof, belonging to the field of regeneration and utilization of resources. The processing method comprises the following steps: (1) putting crop straw and rice straw in a pulverizer together for crushing, wherein, the mass ratio of the crop straw of cotton straw to rice straw is 2-7:3; (2) carrying out spraying with water 10 to 12% heavy of the total crushed crop straw and rice straw which and carrying out uniform mixing; (3) pressing the mixture of crop straw and rice straw obtained in step (2) into blocks with a granulator so as to obtain the straw solidified carbon rods. According to the invention, a process flow for preparing the straw solidified carbon rods is simple; used processing raw materials are simplex and are mainly straw crops; a good shaping effect is obtained; solidified carbon rods has a sulfur content far lower than common coal dose, has high heat of combustion and high utilization efficiency, and is convenient to transport and store.
Description
Technical field
The complete processing and the stalk that the present invention relates to a kind of resource regeneration utilize product again, relate in particular to a kind of straw solidification carbon-point and working method thereof.
Background technology
The energy is the important foundation of the national economic development, is that human being's production guarantees with the essential base substance of life.Power supply at present mainly is fossil fuels such as dependence coal, and environmental pollution that the finiteness of fossil energy resource and development and use thereof cause and greenhouse gas emission have produced serious restrictive function to economic Sustainable development with society.China is an Energy production and consumption big country, in the process of building a well-off society in an all-round way, how to improve energy structure, guarantees the Sustainable development that energy security facilitates economic and social, and is the great strategic issue that China faces.
At present, China's emission of carbon-dioxide total amount has exceeded the U.S. and has ranked first in the world, CO2 emissions 70%, sulphur dioxide emission 90%, nitrogen oxide emission 66.7% all come spontaneous combustion coal.China is faced with the dual problem of resource exhaustion and environmental pollution.Stalk is a kind of precious resources, and in recent years, because stalk can not get reasonably utilizing for a long time again, major part is directly burnt, and causes the serious wasting of resources and becomes the major source of pollutant on the agricultural.
Chinese patent " novel biomass stalk coal briquette " (application number: 200810182704.X; The applying date: 2008-12-03) disclose a kind of environment-friendly type coal cinder that utilizes straw powder and the moulding of colliery powder extrusion to process; The raw material that this method adopts has been sneaked into coal gangue; Cost is higher, and adds entry and carry out after the extrusion molding incomplete combustion and can produce sulfide gas environment is polluted.Chinese patent " bio-coal and the working method " (patent No.: 200910230636.4; The applying date: 2009-11-22) disclosing a kind of is main with cotton, wheat, corn straw; Collocation paper mill tankage are processed, and the bio-coal calorific value that this method is produced is at 3629 kilocalories/kilogram, and rate of combustion reaches 90%; But technology is comparatively complicated; Raw materials for production are various, and proportioning is complicated, bad penetration and promotion utilization.
Summary of the invention
Goal of the invention: the object of the present invention is to provide that a kind of technical process is simple, the process for processing working method of straw solidification carbon-point easily; Another object of the present invention is to provide a kind of straw solidification carbon-point of best in quality, energy-conserving and environment-protective.
Technical scheme: for realizing above-mentioned purpose, the working method of a kind of straw solidification carbon-point of the present invention comprises the steps:
(1) crop material and rice straw are put into kibbler together and pulverize, the mass ratio of said crop material and rice straw is 2 ~ 7:3;
(2) crop material after will pulverizing and rice straw spray and mixing by 10 ~ 12% of gross weight;
(3) crop material that step (2) is obtained and the mixture of rice straw obtain the straw solidification carbon-point through the nodulizer compound stalk forming.
Said crop material comprises any one perhaps its mixing of wheat straw stalk, corn straw, cotton stalk.As further optimization of the present invention, said crop material
Said crop material and rice straw are crushed to 40 ~ 60 orders after crushed.In order to prevent dust, can sprinkling equipment be set at the kibbler discharge port, directly regulate water cut through the control spray flux.
Because wheat straw stalk appearance has slick stratum corneum, only through mechanical presses, the molding effect of wheat straw stalk is poor; And can effectively increase system interphase interaction power through adding rice straw, make stalk forming effective.It is trickle expanded through trickle Mierocrystalline cellulose in the stalk to be taken place, and has further strengthened stickiness through extrusion molding again.
For a kind of straw solidification carbon-point that makes according to aforesaid method, the density of said carbon-point is 700 ~ 1400kg/m
3, ash content is 1 ~ 20%, moisture≤15%, calorific value are 3500 ~ 4500 kcal/kg.
Said carbon-point sulphur content is 0.16 ~ 0.22%, and the ashes after the burning are rich in elements such as calcium, magnesium, phosphorus, potassium, sodium, are good mineral manure.
Beneficial effect: the working method technical process of straw solidification carbon-point of the present invention is simple, process raw material single and be main crops stalks, and this method sprays with moisture through the reasonable raw material proportioning and makes the stalk carbon-point have extraordinary molding effect; The straw solidification carbon-point sulphur content that the working method of straw solidification carbon-point of the present invention makes is far below general coal, and combustion heat value is high, and utilising efficiency is high, is convenient to transportation, stores.
