Description
Technical field
The present invention relates to a kind of coal water slurry fuel, the preparation method of concrete environment-friendly biomass coal water slurry.
Background technology
Coal water slurry is that one can pumping, and the coal based fluid fuel of atomization replacing oil combustion, it is by the coal dust of 60% ~ 65%, the water of 35% ~ 40%, and the chemical additive of about 1% processes through certain technical process, has the fluid of certain mobility.It changes the traditional combustion mode of coal, demonstrates great environmental protection and energy saving advantage.
In recent years along with China in recent years greatly develop livestock industry, the problem of environmental pollution that livestock industry causes becomes increasingly conspicuous.For cattle farm, every adult dairy cattle approximately discharges the cow dung of 35kg, the ox urine of 18kg every day.In the plant of intensive manufacture, the cow dung that every day produces, urine are huge source of pollution.Then the dried combustion value of cow dung (5200kcal/kg) is close with coal, in ox urine except the compounds such as urea, and the soluble potassium also containing 1.2-1.4%.In today that resource is day by day deficient, cow dung, ox urinate such resource, it can be used as the raw material of production coal water slurry, namely can reduce the consumption of water and Nonrenewable resources coal when preparing coal water slurry, can solve again day by day serious Livestock Production Pollution problem.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of biomass coal-water slurry, and the present invention processes coal dust in rear cow dung Some substitute coal water slurry, decreases the consumption of coal resource; Use the rear cow dung of process, reduce the add-on of additive in coal water slurry, product performance are up to state standards simultaneously.Ox urine of the present invention or breeding wastewater instead of tap water, potassium content in coal water slurry is improved, containing the coal dust obtained after the burning of potassium biomass coal-water slurry, has higher potassium content, can be applied to soil as soil improvement agent.By the preparation containing potassium biomass coal-water slurry, realize comprehensive utilization of resources, solve the environmental pollution of cow dung and ox urine or breeding wastewater.
Technical scheme of the present invention is: a kind of biomass coal-water slurry, and coal water slurry butt is that cow dung after being processed by weight part 20-50 part, 80-50 part coal dust and 0-1.5 part slurries additive agent are made; In coal water slurry, water-content accounts for 35-40%, and except the water carried in cow dung after process, additionally adding water section is ox urine or breeding wastewater, and ox urine or breeding wastewater usage quantity account for the 50-100% of total Water.
After process, cow dung refers to that peralcohol, breeding wastewater or ox urinate, cow dung mixes in proportion, obtained after reacting by heating, wherein the add-on of peralcohol is the 5-15% of cow dung butt weight, the add-on of breeding wastewater or ox urine is the 0-300% of dry cow dung weight, the 0-100% of wet cow dung weight.
The pH value of the mixture that process cow dung obtains is greater than 9; When pH is less than 9, hydro-oxidation sodium or potassium hydroxide regulate.
The peralcohol that process cow dung is used is hydrogen peroxide, sodium peroxide, Potassium peroxide or its mixture.
The temperature range of reacting by heating is 65 ~ 90 degrees Celsius.
The time 5-24 hour of reacting by heating.
The mixed solution of peralcohol, breeding wastewater and cow dung is after reacting 5-24 hour, and this mixture water content will be down to 55-75%.
So-called slurries additive agent refers to anionic additive methyl naphthalene sulfonic acid salt formaldehyde condensation products, sulfonated lignin, naphthalenesulfonate formaldehyde condensation compound, methanonaphthalene sodium sulfonate or tar system sulfonate.
A preparation method for biomass coal-water slurry, after processing, cow dung, coal dust and slurries additive agent mixing, prepare coal water slurry by wet grinding mill slurry processes; Water required in preparation process has in cow dung and carries or additional ox urine or breeding wastewater as required, and ox urine or breeding wastewater add-on are the 50-100% of total water consumption, prepare the coal water slurry of moisture 35-40%.
Beneficial effect of the present invention: the present invention processes coal dust in rear cow dung Some substitute coal water slurry, decreases the consumption of coal resource; Use the rear cow dung of process, reduce the add-on of additive in coal water slurry, product performance are up to state standards simultaneously.Ox urine of the present invention or breeding wastewater instead of tap water, potassium content in coal water slurry is improved, containing the coal dust obtained after the burning of potassium biomass coal-water slurry, has higher potassium content, can be applied to soil as soil improvement agent.By the preparation containing potassium biomass coal-water slurry, realize comprehensive utilization of resources, solve the environmental pollution of cow dung and ox urine or breeding wastewater.In the coal ash obtained after obtained cool water mixture burning, the content of soluble potassium salt can higher than 2%.
