Abstract
The present invention discloses sludge coal water slurry and a manufacturing technology thereof. The present invention aims at solving the existing problems of environmental pollution and influence to city construction which are caused by piling sludge from urban water treatment, need of combustible matter to ignite the dewatered and dried sludge, insufficient combustion and large amount of residue. The sludge from urban water treatment, final products of coal water slurry and a dispersing agent are added to a cylindrical grinding mill, ground and mixed, and the mixture is filtered by a filter to obtain the particles with a particle diameter of smaller than 0.5mm of the sludge coal water slurry which are transported to a special coal water slurry boiler for combusting. The sludge coal water slurry has simple manufacturing technology, consumes less energy and serves as the fuel for special coal water slurry boilers, and the burn-out rate of the sludge coal water slurry can reach 98%. The present invention does not only greatly reduce the damage to city caused by the sludge from sewage treatment, but also changes waste into resources, so the combustible matter in the sludge obtains sufficient combustion, a large quantity of energy sources are saved, and the problem of consumed coal shortage is released.
Description
Technical field
The invention belongs to boiler oil, specifically a kind ofly municipal sludge can be added the technology of making coal water slurry boiler incendiary sludge water-coal-slurry fuel in the coal water slurry and making this fuel.
Background technology
In recent years, rapid economy development has driven quickening of urbanization process, the municipal sewage treatment amount is also increasing, the amount of sludge that produces after the sewage disposal increases thereupon, be example only with small and medium-sized cities, the active sludge that sewage work produces reaches more than 100 tons every day, and this quantity is also in continuous growth, and metropolitan water treatment sludge quantity is just more.Because of the rapid increase of municipal sludge and can't dispose, brought serious pollution to The Surroundings in Cities, also be provided with very big obstacle to urban construction, water treatment sludge has become one of bottleneck of urban development.According to survey, the calorific value of the mud after the municipal sewage treatment reaches about 3550kj/kg, can utilize combustiblematerials recovery heat wherein to utilize with the mode reduced volume of burning fully again.Existing minority is to the burning disposal of municipal sludge, mostly is earlier mud to be collected and dehydrated to add a large amount of combustiblematerialss again after the processing and ignite, and puts into as normal conventional boilers such as grate furnaces and burns.This burning mode is lower because of sludge calorific value on the one hand, causes fire box temperature low, and it is insufficient to burn, and callable heat is also few; Moreover also have the inadequate residual solids slag of more burning after the burning, without handling the obstacle that also can become urban construction again.
Summary of the invention
The objective of the invention is to overcome existing city water treatment sludge stacks contaminate environment, influences urban construction, and to ignite with a large amount of combustiblematerialss after dehydrating, it is insufficient to burn, the problem that residual slag is more provides boiler dedicated incendiary sludge water-coal-slurry of a kind of coal slurry that supplies water and manufacture craft thereof.
In order to solve the problems referred to above that prior art exists, feed composition weight proportion umber of the present invention is:
3-6 parts of moisture 70-85% city water treatment sludge
7-9 parts of moisture 30-40% finished product coal water slurry
0.05-0.1 part of finished product dispersion agent.
Described finished product dispersion agent can be any one in finished product naphthalene sulfonic acidformaldehyde condensation product, humate, the sulfonated lignin.
Optimum feed stock composition weight proportioning umber of the present invention is:
5 parts of moisture 70-85% city water treatment sludge
8 parts of moisture 30-40% finished product coal water slurry
0.08 part of finished product dispersion agent.
Described finished product dispersion agent can be any one in finished product naphthalene sulfonic acidformaldehyde condensation product, humate, the sulfonated lignin.
The manufacture craft of above-mentioned sludge water-coal-slurry is: city water treatment sludge with moisture 70-85% and moisture 30-40% finished product coal water slurry, and the finished product dispersion agent adds tubular grinding machine ground and mixed jointly, filter through filter, particle diameter is delivered to the basin of finished product sludge water-coal-slurry less than the particle of 0.5mm.
Sludge water-coal-slurry particle diameter in the sludge water-coal-slurry basin accounts for 70%-75% less than 0.038mm, and its combustion efficacy is better, accounts for 75% for best.
Advantage of the present invention and positively effect are, because the mud after the municipal sewage treatment contains multiple combustiblematerials, and coal water slurry boiler is current more sophisticated efficient boiler, and its burnout rate reaches as high as 98%.Mud after the municipal sewage treatment does not need to dehydrate processing, therefore do not want dehydration equipment, do not waste energy, can directly itself and coal water slurry be passed through simple ground and mixed in the tubular grinding machine, being equipped with increases its additive mobile and stability again, make sludge water-coal-slurry with aforesaid method, because its granularity is little, be pumped to the coal water slurry jet atomization burner combustion of installing on the coal water slurry boiler, can reach abundant burning, the amount of its residue is very little, only about 7%, and all become thin Powderedly basically, this ashes can also be done material of construction usefulness, thereby can thoroughly handle mud clean.Above-mentioned sludge water-coal-slurry manufacture craft is simple, consumed energy is few, make fuel for the dedicated water fluid-fired boiler, can not only significantly reduce of the harm of the mud of sewage disposal to the city, but also can turn waste into wealth, combustiblematerials in the mud is fully burned, can saves a large amount of energy, can also alleviate present problem simultaneously with the coal anxiety.After tested, above-mentioned sludge water-coal-slurry calorific value replaces existing finished product coal water slurry to make fuel for the dedicated water fluid-fired boiler up to 15Mj/kg with sludge water-coal-slurry, can save coal 20%.With existing 20 tons/time coal water slurry boiler dedicated be example, 100 tons in the mud of every day Treating Municipal Sewage processing, the active sludge that sewage work produces as long as one 20 tons/time boiler can digest, day is saved 80 tons of finished product coal water slurry, and its economic benefit and social benefit are all considerable.
