Specification

Raw material manufacturing facility for cement production, cement manufacturing plant, and waste cement raw material conversion method

Technical field

[0001] The present invention relates to a cement production raw fuel production facility for effectively treating wastes such as metropolitan trash as a raw material for cement production, a cement production plant equipped with this facility, and The present invention relates to a method for converting waste into a raw material for cement. Background art

[0002] Conventionally, since the amount of organic waste such as soot has increased, many proposals and attempts have been made regarding effective treatment methods and reuse methods. As one method, it has been proposed to ferment (compost) organic waste using a rotary fermenter. Patent Document 1 also describes that organic waste is fermented with a cement kiln or used as part of fuel for cement production.

[0003] However, as described in Patent Document 1, it has been difficult to stably compost organic waste even if a cement kiln is simply used as a fermentation treatment apparatus. Attempts have also been made to use fermented products as raw materials for cement production, but it has proven difficult to efficiently obtain high-quality fermented products.

[0004] Therefore, in order to make effective use of cement kilns and other cement manufacturing equipment for waste disposal, the present applicant uses a rotary kiln or a rotary dryer to dispose of wastes such as city garbage stored in garbage bags. A method of fermenting by directly putting it into a rotary kiln or rotary dryer was proposed (see Patent Documents 2 and 3).

[0005] For example, a cement manufacturing plant for carrying out this method has a cement manufacturing raw material manufacturing facility 400 attached to a cement manufacturing facility 300 as shown in FIG.

[0006] The cement production facility 300 was discharged from a rotary kiln 302 and a rotary kiln 302, which is equipped with a supply pump 310 for supplying liquid fuel such as a parner 308 and heavy oil, etc. Clinic power cooler 303 that cools cement cleansing power by cooling wind turbine 312 and Pana 314 And a suspension preheater 306 in which cyclones 307 are stacked in multiple stages to preheat cement raw materials.

[0007] On the other hand, the raw fuel production facility 400 for cement production is roughly divided into a fermentation treatment apparatus 402, storage and fermentation treatment tanks 404 and 406, and a fermentation process in order to perform fermentation treatment (composting) of waste. Equipped with separation and removal devices 408 to 418, etc.

[0008] At the inlet of the fermentation treatment apparatus 402, there are provided inlets 420, 422, 424 and a fermentation gas outlet 426 for feeding the waste garbage, sewage sludge, and the fermented product for return. The fermentation gas outlet 426 is provided with a ventilation wind turbine 419 as an exhaust means. On the other hand, a fermented product outlet 428 and an air inlet 427 are provided at the outlet of the fermentation treatment apparatus 402. The air inlet 427 is provided with an air inlet wind turbine 429 as an air supply means.

[0009] The storage and fermentation processing tanks 404 and 406 are provided for further proceeding fermentation in the fermentation processing apparatus 402 and temporarily storing the fermented products, and are provided with a quantitative drawer at the bottom for quantitative determination. The fermented processed product having the extractor power can be supplied to both the supply line 430 to the cement production facility 300 and the return line 432 to the fermentation processing apparatus 402.

[0010] Equipments 408 to 418 provided in the subsequent stage of the fermentation treatment apparatus 402 are for removing foreign substances from the fermented product, and include a magnetic separator 408 provided with a benolet conveyor 409 and a primary crusher 410. It consists of a Trommel 412, a high Gaussian sorter 414, an aluminum sorter 416, and a secondary lithotripter 418.

[0011] Next, a fermentation treatment method in a cement manufacturing plant having the above-described configuration will be described.

[0012] Fermentation processing apparatus 402 of raw material production facility 400 for cement production is charged with waste trash from the trash slag inlet 420 and sewage sludge at the sewage sludge 422 in addition to the trash sewage. . Further, a part of the fermented product is returned from the storage and fermentation processing tank 406 to the fermenting device 402 through the line 432. This is for the purpose of stabilizing the cells in the fermentation treatment apparatus 402 and stabilizing the quality of the fermentation treatment product.

[0013] The waste moves in the fermentation treatment apparatus 402, and after 3 days, the fermentation treatment product is taken out from the outlet 428. During fermentation, fermentation proceeds by a mechanism such as aerobic degradation of easily degraded components by fermenting bacteria that inhabit the natural world at the entrance. Meanwhile, during the fermentation process, From the fermentation gas outlet 426, the fermentation gas in the fermentation treatment apparatus 402 is drawn out by the wind turbine 419 and introduced into the calcining furnace 304, etc., where ammonia generated in the fermentation process is decomposed to deodorize the exhaust gas. . In addition, air is supplied from the air blowing port 427 by the air blowing wind turbine 429 to maintain the aerobic condition in the fermentation treatment apparatus 402 and to maintain fermentation by aerobic bacteria.

[0014] The fermented processed product obtained as described above is removed by using a magnetic separator 408, a high Gaussian sorter 414, and an aluminum sorter 416 to remove iron, stainless steel, and aluminum, respectively. . Further, the fermented product is adjusted to an appropriate particle size by the primary crusher 410 and the secondary crusher 418.

[0015] The fermented processed products are sent as raw materials for cement production to the storage tanks for fermenting and fermenting processing 404, 406 by the packet elevators 442, 443, and are circulated by the circulation system. That is, under the tanks 404 and 406, benoreto conveyors 444 and 446 are installed. Fermented products partially taken out from these are vertically transported by the packet elevator 448 and stored again for storage and fermentation processing tanks. Return to 404, 406. As a result, the aerobic state is maintained. The fermented product is supplied as a raw material for cement production from the line 430 to the cement manufacturing facility 300 via the belt conveyor 450 or returned to the fermenting device 402 via a part of the line 432.

On the other hand, the cement manufacturing facility 300 manufactures cement in parallel with the operation of the cement manufacturing raw fuel manufacturing facility 400. The cement raw material is preheated in each cyclone 30 7 in the suspension preheater 306, calcined in the calcining furnace 304, and calcined in the rotary kiln 302. The raw fuel for cement production obtained by the raw fuel production facility 400 for cement production is used as a fuel for firing in the rotary kiln 302 or as a fuel for calcining in the calcining furnace 304. From line 430 to kiln bottom or calcining furnace 304 of rotary kiln 302.

Disclosure of the invention

Problems to be solved by the invention [0018] The cement production facility 300 with the above-mentioned raw fuel production facility 400 for cement production is operated for about 2 to 3 weeks at a rate of 2 to 3 times a year by maintenance and inventory adjustment of the rotary kiln 302 and the like. It is normal to pause. However, even when the cement production facility 300 is out of service, the raw material production facility 400 for cement production still accepts waste and undergoes fermentation treatment, so it can be used as raw fuel in the cement production facility 300. The apportionment must be temporarily stored in the storage and fermentation tanks 404 and 406 of the raw material production facility 400 for cement production until the cement production facility 300 resumes operation.

[0019] However, as described above, the suspension of the cement production facility 300 is continued for about 2 to 3 weeks, so that a large amount of fermentation processed products should be temporarily stored in the storage and fermentation processing tanks 404 and 406. Therefore, in order to increase the storage capacity of the storage and fermentation processing tanks 404 and 406, it is necessary to make them large-scale, and there is a problem that the equipment cost increases.

[0020] Therefore, the present invention was made in view of the problems in the conventional raw material production facility for cement production and the like, and is a raw material production facility for cement production that does not cause an increase in equipment cost. The purpose is to provide a raw material production facility for cement production that can easily handle fermented products processed by the raw material production facility for cement production during the suspension period of the cement production facility attached And

Means for solving the problem

[0021] The present invention is a raw fuel production facility for cement production, which stores an aerobic fermentation treatment device for fermenting waste and a fermentation treatment product fermented by the aerobic fermentation treatment device. And a storage warehouse.

[0022] Here, as the aerobic fermentation treatment device, a rotary kiln type, scoop type, auger type, paddle type device, etc. used for composting organic waste can be used. It is also possible to use a rotary kiln or rotary dryer that has been removed. In addition, as a storage warehouse, for example, a sealed building such as a tent house can be used, and materials such as an outer wall and a ceiling are not limited.

Note that in this specification, “waste” includes the following objects to be treated.

(1) Organic sludge: Sewage sludge, human waste sludge (septic tank sludge, agricultural settlement wastewater sludge), food industry wastewater sludge, ako 'bottom sludge, etc. are included in this category.

It is possible to reliably treat the received waste without incurring a rise in the price.

[0025] In the storage warehouse of the raw fuel production facility for cement production, anaerobic fermentation accompanied by generation of methane, hydrogen sulfide and the like of the fermented product can be suppressed. It is desirable that the maximum deposition height of the fermented processed product in the storage warehouse is 2 m or more and 5 m or less. Further, the volume of the fermented processed product stored in the storage warehouse with respect to the total volume of the storage warehouse can be 10% or more and 40% or less. In normal compost facilities, there is an aeration facility as a secondary fermentation facility. However, since there is no need for secondary fermentation in a raw fuel production facility for cement production, the equipment was reduced by eliminating the air blowing facility. In this case, as it is, anaerobic fermentation accompanied by generation of flammable gas such as methane will occur and the risk of explosion will increase, so it is necessary to suppress it. By setting the maximum deposition height of the fermented product to 5 m or less, anaerobic fermentation inside the sedimentary layer can be more effectively suppressed.

[0026] Further, a ventilation device for air in the warehouse of the storage warehouse for removing odors and a small amount of flammable gas such as methane generated during storage from the fermented processed product and filling the warehouse, And a deodorizer for treating the ventilation air. As ventilation equipment If the air in the warehouse, such as a suction fan, is discharged to the outside,

It is preferable to ventilate the entire storage warehouse at least three times per hour. As the deodorizer system, various deodorizers used in composting facilities such as plasma system, ozone system, adsorption system, chemical cleaning system, combustion system, biological deodorization system, etc. can be applied. Further, the storage warehouse can be provided with a detector for monitoring the concentration of combustible gas in the warehouse.

[0027] Further, when the fermented processed product is used as a part of raw fuel in a cement production kiln in the storage warehouse, the dosage in the cement production kiln is 1 day or more and 30 days or less. Is preferably storable. As a result, it is possible to temporarily store all the fermented processed products that cannot be processed within the suspension period due to normal maintenance and inventory adjustment.

[0028] Further, the present invention is a cement manufacturing plant, characterized in that the raw fuel manufacturing facility for manufacturing cement is attached. When the cement manufacturing plant is equipped with the raw material manufacturing facility for cement manufacturing, even if the rotary kiln of the cement manufacturing plant stops operation due to maintenance, etc., the fermented processed products that have been fermented from the received waste are stored in the storage warehouse. It can be stored, and after resuming operation of the rotary kiln, fermented products stored in the storage warehouse can be used as raw fuel for cement production, so that the received waste can be treated reliably. The raw fuel production facility for cement production and the storage warehouse do not have to be on the same site as the cement production facility.

[0029] Further, the present invention is a method for raw cement fuel for waste, wherein the waste is fermented with an aerobic fermentation apparatus, and the fermented fermented product is stored in a storage warehouse. The stored product is carried into a cement production facility, and the fermented product carried into the cement production facility is used as a raw material fuel for cement production.

[0030] According to this method of converting waste into raw cement fuel, the cement manufactured by the raw fuel manufacturing facility for manufacturing cement is stored in a storage warehouse by storing the fermented product fermented by an aerobic fermentation apparatus. Even when a rotary kiln that uses raw fuel for fuel is suspended due to maintenance, etc., fermented products obtained by fermenting the received waste can be used as raw material for cement production after the resumption of rotary kiln operation. Ensure waste Can be processed.

[0031] In the method of converting waste into raw cement fuel, the aerobic fermentation apparatus preferably performs aerobic fermentation treatment on the waste for 12 hours or more. In addition, anaerobic fermentation of the fermented processed product can be suppressed in the storage warehouse, and the volume ratio of the fermented processed product stored in the storage warehouse to the total volume of the stored warehouse is 10% or more, 40 %, And the accumulation height of the fermented processed product in the storage warehouse can be 2 m or more and 5 m or less.
