Description
Technical field
The present invention relates to a kind of preparation methods of clinker, cure landfill system in particular with shale gas drilling well solid waste
The method of standby clinker.
Background technology
Generate a large amount of drilling well solid waste in shale gas drilling process, including well drilling detritus, discarded slurry, waste water flocculating body and
Other wastes, ingredient are mainly a variety of stable state colloids of the compositions such as clay, drilling cuttings, sewage, chemical treatment regimens and sump oil
Suspension system, harmful components are complicated.At present for shale gas drilling well solid waste, the disposal options generally used are in well site wastewater disposal basin
In solidification landfill stabilization directly carried out by curing agent, which is simple and practicable.Such as Chongqing City's shale gas first stage of the project, two
Lime-ash after water base drilling cuttings, waste water-base mud and the sewage sludge of over one hundred mouthful of well, oil-based drill cuttings de-oiling takes cement solidification
Landfill stabilization, about more than 200, solidification landfill pond, floor space is wide.As it can be seen that the disposal options of solidification landfill occupy a large amount of soil
Ground resource, and this kind of disposal options also have larger security risk.For example Sichuan puguang gas field is leaked because of pond body, no
It obtains not dig out the solid waste of landfill solidification landfill body all and remarket.Current national requirements for environmental protection dynamics increasingly increases, state
Shale gas solid waste is cured landfill body and carries out comprehensive resource profit by gesture high pressure in order to meet increasingly strict environmental protection requirement
With being current and developing direction from now on and trend.
At the same time, the especially traditional construction material industry of the building materials industry in China is that natural mineral resource and energy consumption are high
Industry, 5,000,000,000 tons of various resources will be consumed by producing various construction materials every year, consume 2.3 hundred million tons of standard coals of the energy, give resource
White elephant is brought with environment, cement production enterprise requires own existence and development, it is necessary to establish and contribute for environmental protection
Thought economizes on resources, is energy saving, turning waste into wealth, and makes single cement production enterprise, is transformed into the enterprise of comprehensive utilization of resources
Industry.
It is well known that cement kiln has the characteristics that burning furnace temperature height and processing inventory are big, and cement plant is equipped with
A large amount of environmental protection facility is the strong equipment of the self-purification ability of enviroment.Solid waste is handled using cement rotary kiln, not only has and burns
The volume reduction of method, minimizing feature, and the residue after burning becomes a part for clinker, need not be carried out to burning ash secondary
Processing, is a kind of recycling treatment approach to make the best of both worlds.
Cure the solid waste such as landfill body using shale gas drilling well solid waste and produce clinker, both widens raw material
Source reduces the consumption of a large amount of natural resources, greatly reduces the cost of manufacture of cement, and protects natural environment, is conducive to
Sustainable Development of Cement Industry；Currently, directly curing the side that landfill body does raw material for producing cement chamotte with shale gas drilling well solid waste
Case yet there are no document report.
Invention content
Curing the method that landfill body prepares clinker using shale gas drilling well solid waste the object of the present invention is to provide a kind of,
Shale gas drilling well solid waste solidification landfill body can be utilized to prepare qualified clinker, to realize the money of shale gas drilling well solid waste
Sourceization utilizes.
It is of the present invention to cure the method that landfill body prepares clinker, including following step using shale gas drilling well solid waste
Suddenly：
(1) dispensing：30~75 parts by weight of shale gas drilling well solid waste solidification landfill body, 10~35 parts by weight of diatomite, shell
10~35 parts by weight of powder, 1~5 parts by weight of sulfate slag；
(2) cement slurry processed：Shale gas drilling well solid waste is cured into landfill body and is broken into the particle that grain size is 5~15mm, silicon
Diatomaceous earth is broken into the particle that grain size is 5~15mm, and raw mill is entered together with sulfate slag, and it is more than 53~75 μm of square hole screens to obtain grain size
In 8~15% cement slurry；
(3) producing cement clinker：By cement slurry through skewed slot be conveyed into preheater be classified, preheat after send to rotary kiln；
It is slurry more than 53~75 μm of square hole screens 8~15% that oyster shell whiting, which is shell through wet ball grinding into grain size, and oyster shell whiting slurry is aqueous
Rate is 60~80%, and oyster shell whiting slurry is pumped in rotary kiln, is calcined together with the material in rotary kiln, temperature 1300~
1700 DEG C, 35~50 minutes time is to get clinker.
The diatomite is a kind of pure natural nonmetallic mineral, is gradually formed by Diatomeae remains in ocean or lake
Sedimentary rock.
The oyster shell whiting be by scallop shell or/and snail shell through wet ball grinding at slurry.
The oyster shell whiting slurry is pumped to rotary kiln by helicoidal pump, then enters in rotary kiln from rotary kiln.
Since the temperature of rotary kiln is higher than the temperature of rotary kiln end, oyster shell whiting slurry enters rotary kiln from rotary kiln
In can play the role of drying oyster shell whiting slurry.
The grain size of the sulfate slag is 0.1~5mm.
The shale gas drilling well solid waste solidification landfill body is using inorganic silicate reinforcing agent, coagulant, gel breaker, absorption
After agent and pH adjusting agent carry out curing process to shale gas drilling well solid waste, the solids with certain compression strength and water resistance.
I.e. by curing agent --- inorganic silicate reinforcing agent, coagulant, gel breaker, adsorbent and pH adjusting agent and shale gas drilling well solid waste
After carrying out uniform stirring mixed processing, compressive strength of solidified body and leachate meet petrochina company standard《Drilling wastes
Innoxious process for treating specification》Related requirement in QSY XN 0276-2015.
Inorganic silicate reinforcing agent in the curing agent can be portland cement, and coagulant can be CaO, and gel breaker can be
FeCl3, adsorbent can be flyash, and pH adjusting agent can be (NH4)2SO4, and the content of each component is in curing agent：Inorganic silicon
135~155 parts by weight of hydrochlorate reinforcing agent, 60~70 parts by weight of coagulant, 3~7 parts by weight of gel breaker, 65~75 weight of adsorbent
Part, 9~15 parts by weight of pH adjusting agent；When curing process, the addition of curing agent in the shale gas drilling well solid waste per kilostere
It is 280~320 tons.
The beneficial effects of the invention are as follows：
1, the present invention cures landfill body as primary raw material, so as to avoid shale as a result of shale gas drilling well solid waste
Pneumatic drill well solid waste cures landfill stabilization occupying and waste to soil, thoroughly solves shale gas drilling well solid waste solidification landfill stabilization
Existing Environmental security hidden danger afterwards, and secondary pollution, ring will not be caused using the method for the present invention production clinker in the process
Protect remarkable benefit.
2, the present invention realizes clinker production to limited nature since the raw materials such as lime stone, clay, shale are not used
Zero consumption of resource promotes " no pollution, zero power consumption, zero-emission, zero consumption and the negative increasing of solid waste of the production of cement industry enterprise
Length " is implemented, and resource circulation utilization and green ecological cement production, remarkable in economical benefits are realized.
3, the present invention can facilitate using existing dry-process rotary kiln production line equipment and technology, and operability is strong, be conducive to cement and give birth to
Enterprise is produced to environmental type industrial transformation.
