Abstract
The invention discloses a method for preparing a novel gasification compound type coal binding agent.The method mainly includes the steps that coal dust and bentonite serve as timber in cooperation with solvent water and a catalytic natrium agent, a high-temperature high-pressure reaction is conducted in reduction gas, and the briquette binding agent is obtained.The method is mainly characterized in that auxiliary materials including cotton stalk, peanut shell materials, dry weeds and cow chip are added, and the specific method and steps are disclosed.According to the method, multiple types of materials commonly seen in rural areas serve as the auxiliary materials, and the cow chip which can achieve a quite good combustion-supporting effect is added, so that the prepared briquette binding agent is not only good in pressure resistance but also complete in combustion, meanwhile lowers the cost of the binding agent and has great economical and social benefits.
Description
Technical field
The preparation method that the present invention relates to a kind of briquette binder, the preparation method particularly relating to a kind of Novel gasification composite coal binder.
Background technology
Briquette binder (also referred to as briquette binder, briquette adhesive, composite adhesive for briquette etc.) is the fuel of the powderies such as coal dust to bond (knot), reinforcing together, is beneficial to the blender of molding in bulk；Ensure after molding that moulded coal has the powdery of specific shape and performance or the moulded coal auxiliary material of liquid；It is mainly used in moulded coal processing technique and plays assosting effect.Coal briquette bond is the crucial auxiliary material determining briquet quality.
Briquette binder is that inorganic matter forms through complicated chemical reaction with multiple Organic Chemicals, adds fine coal and quickly forms pin network structure, so that moulded coal (coal briquette) has significantly high hot and cold mechanical strength and heat stability；Significantly high protection against the tide, water resistance and water logging intensity；Putting into fuel value in stove high, after burning, calorific intensity is high, and whereabouts percentage of damage is low, without ash, pollution-free, simple to operate.
From current practical application, wheat stalk is adopted to add, as adjuvant, the Application comparison making briquette binder in the middle of fine coal at present extensive and ripe, but some area lacks wheat stalk, therefore, whether can substitute wheat stalk as adjuvant with other crops, it may be that the emphasis of a research.
Summary of the invention
The purpose of the present invention is exactly the preparation method proposing a kind of Novel gasification composite coal binder, this preparation method makes briquette binder with other crops as adjuvant, and making the briquette binder comprcssive strength being made better, burning is more abundant, and economy is also better.
For reaching above-mentioned technical purpose, the preparation method that present invention employs a kind of Novel gasification composite coal binder, its described method mainly with coal dust and and bentonite for timber, it is equipped with aqueous solvent and catalysis sodium agent, reducibility gas carries out high-temperature high-voltage reaction, prepares briquette binder, the big characteristic of the one of the present invention, also residing in and add cotton stalk, Pericarppium arachidis hypogaeae material, weeds siccative, dry four kinds of adjuvants of cattle manure, its concrete grammar step is as follows:
(1) by 100 parts of cotton stalks, 100 parts of Pericarppium arachidis hypogaeae material and 100 parts of weeds siccative warm water washes clean, and it is put under natural temperature and dries；
(2) dry cattle manure, cotton stalk, Pericarppium arachidis hypogaeae material, weeds siccative pulverizer are ground into 100-150 order；
(3) after the coal dust of 200-220 order, the bentonite of 120 orders, aqueous solvent and catalysis sodium agent being 70-80 part, 50-70 part, 3-5 part Homogeneous phase mixing by mass parts, add dry cattle manure, cotton stalk, Pericarppium arachidis hypogaeae material, weeds siccative mixture, and be sufficiently stirred for mixing；
(4) being implanted in high-pressure reactor by step (3) mixture, and pass into reducibility gas, adjustment initial pressure is 6Mpa；
(5) reactor being warming up to 300-310 DEG C, the response time is 60-70 minute, and control reaction pressure is 40-45Mpa, reacts；
(6) after reaction terminates, reactor is slowly cooled to room temperature, takes out reactant mixture material, water and solid material are extruded or centrifugation, obtains solid product, be briquette binder.
The present invention adopts the common material in multiple rural area as adjuvant, and add the dry cattle manure that can reach fine combustion-supporting effect so that the briquette binder produced not only crushing resistance is good, and it is more abundant to burn, also reduce binding agent cost simultaneously, there is very big economic benefit and social benefit.
Detailed description of the invention
The present invention is described in more detail by embodiment in detail below.
A kind of preparation method of Novel gasification composite coal binder, its described method mainly with coal dust and and bentonite for masterbatch, it is equipped with aqueous solvent and catalysis sodium agent, reducibility gas carries out high-temperature high-voltage reaction, prepare briquette binder, the big characteristic of the one of the present invention, also resides in and adds cotton stalk, Pericarppium arachidis hypogaeae material, weeds siccative, dry four kinds of adjuvants of cattle manure, and its concrete grammar step is as follows:
(1) by 100 parts of cotton stalks, 100 parts of Pericarppium arachidis hypogaeae material and 100 parts of weeds siccative warm water washes clean, and it is put under natural temperature and dries, dry this step and to do fully, make every effort to make the moisture of above-mentioned three kinds of materials dry completely；
(2) dry cattle manure, cotton stalk, Pericarppium arachidis hypogaeae material, weeds siccative pulverizer are ground into 100-150 order；
(3) after the coal dust of 200-220 order, the bentonite of 120 orders, aqueous solvent and catalysis sodium agent being 70-80 part, 50-70 part, 3-5 part Homogeneous phase mixing by mass parts, add dry cattle manure, cotton stalk, Pericarppium arachidis hypogaeae material, weeds siccative mixture, and it is sufficiently stirred for mixing, it should be noted that, stirring link must be made fully, and mixing time needs superelevation 10 minutes in principle；
(4) being implanted in high-pressure reactor by step (3) mixture, and pass into reducibility gas, adjustment initial pressure is 6Mpa；
(5) reactor being warming up to 300-310 DEG C, the response time is 60-70 minute, and control reaction pressure is 40-45Mpa, reacts, from result of use, it is proposed that by reaction pressure adjustment and stably to 42Mpa；
(6) after reaction terminates, reactor is slowly cooled to room temperature, takes out reactant mixture material, water and solid material are extruded or centrifugation, obtains solid product, be briquette binder.
Cotton stalk, Pericarppium arachidis hypogaeae material, weeds siccative, dry cattle manure these four material are the common material in rural area, and south and northern area all have, therefore, the acquisition of raw material is more convenient, adopting above-mentioned four kinds of materials as adjuvant preparative caking agent of coal, have bigger economic benefit, cost is greatly reduced.
Generally speaking, the present invention adopts the common material in multiple rural area as adjuvant, and add the dry cattle manure that can reach fine combustion-supporting effect, make the briquette binder not only crushing resistance produced good, and it is more abundant to burn, also reduce binding agent cost simultaneously, there is very big economic benefit and social benefit.
