Abstract
The present invention provides an apparatus for producing municipal solid waste fuel with a fermentation treatment apparatus, which incinerates municipal solid waste through a municipal solid waste incineration facility, stabilizes the calorific value of the municipal solid waste, thereby facilitating the control of the combustibility in the incineration facility, and provides a power generation facility for the municipal solid waste incineration facility.
Description
Technical Field
The invention relates to a technology for incinerating municipal refuse, in particular to a technology for efficiently treating municipal refuse by using a municipal refuse incineration facility.
Background
Most of the domestic garbage and municipal garbage (such as general garbage associated with businesses) are incinerated in a municipal refuse incineration facility, and secondary garbage discharged from the municipal refuse incineration facility (i.e., straw or fluidized-bed furnace) is collected, recovered or buried in the form of incinerator incineration ash and smoke discharged from a dust removal apparatus. From the viewpoint of coping with global warming, the municipal waste incineration facility is expected to improve the combustion efficiency and the efficiency of the power generation function, not only in China, but also in other regions of the world including Asian regions. However, since municipal wastes contain moisture, have a low calorific value, and have a varying moisture content, it is not easy to control the operation of the incinerator when incinerating in a municipal refuse incineration facility. Therefore, especially when the municipal solid waste is incinerated using a municipal solid waste incineration facility equipped with a power generation facility, auxiliary fuel is also used to maintain a constant heating value.
Disclosure of Invention
The present invention has been made in view of the above problems in the prior art, and is useful for controlling combustion stability and calorific value when incinerating municipal refuse using a municipal refuse incineration facility, with the object of improving power generation efficiency and stabilizing power generation of the municipal refuse incineration facility equipped with the facility. In order to solve the problems, the invention provides a municipal refuse incineration facility, which comprises a municipal refuse fuel production facility, a fermentation treatment device for aerobic fermentation of municipal refuse, and a city produced by the municipal refuse fuel production facility and is characterized in that the municipal refuse fuel is used as the fuel of a refuse incinerator.
According to the present invention, the moisture contained in the municipal refuse can be reduced and homogenized by the heat of fermentation of the aerobic fermentation, so that the municipal refuse can be used as a fuel having a stable calorific value in a refuse incinerator. Thereby avoiding the use of auxiliary fuel and making it possible to improve the power generation efficiency and to stably generate power in a municipal refuse incineration facility equipped with a power generation facility.
In the garbage incineration facility, the municipal refuse fuel production facility includes a crusher for crushing the garbage fermented by the fermentation treatment apparatus, a sieve for separating the crushed material by the crusher, and a separator for separating the metal from the separated material by the sieve. In addition, a sorting device is provided, which can separate the waste materials. The waste is extracted by a crusher, the size is homogenized by a sieve to homogenize the whole waste, and the mixing of metal and waste fuel is prevented by a sorting device.
In the refuse incineration facility according to the present invention, an air supply path for supplying odor generated in the municipal refuse fuel production facility to the refuse incinerator may be provided. Thus, additional operating costs can be reduced.
In addition, the present invention is a municipal refuse fuel production facility comprising a fermentation treatment apparatus for aerobic fermentation of municipal refuse and a refuse incinerator for incinerating municipal refuse to produce fuel by fermenting received municipal refuse. The water content in the municipal refuse is reduced by using the fermentation heat of the aerobic fermentation, so that the municipal refuse can be made into fuel with a stable calorific value, and the combustibility in the municipal refuse incineration equipment is controlled.
In the above-mentioned municipal refuse incineration method, when the number of incinerators installed is 1, it may be introduced into the deodorizing means as a method for treating odor generated from the municipal refuse fuel.
As described above, according to the present invention, when municipal refuse is incinerated using the incineration apparatus, on the one hand, control of combustibility is promoted, and at the same time, power generation efficiency and power generation stability in the municipal refuse are improved.
Drawings
Fig. 1 is an embodiment of a municipal refuse incineration facility according to the invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, according to an embodiment of the present invention, a municipal refuse fuel production apparatus 11 ferments with a receiving chamber 13, the receiving chamber 13 receives municipal refuse W1 collected by a garbage truck 12 as domestic refuse and general commercial refuse, a rotary kiln 14 ferments the received municipal refuse W1, the municipal refuse W2 is crushed and sorted, and a storage tank 17 temporarily stores the municipal refuse W3 from a crushing and sorting machine 15. Receiving chamber 13 includes a pit 13a for receiving municipal refuse W1 taken into a cement manufacturing plant, and is provided with a supply conveyor (not shown) for conveying temporarily stored municipal refuse W1 to rotary kiln 14. As rotary kiln 14, a rotary kiln or the like generally used for cement production may be used, and lining bricks are not required.
The sorter 15 has a built-in screen, the crusher and the sorter being integral. The crusher crushes the municipal refuse W2 and applies the crushed municipal refuse W2 to the screen. The pulverized and pulverized material is further pulverized to homogenize the size of the municipal waste W2, and the metal M is recovered from coarse particles and the like temporarily left on the screen. Instead of the crushing and sorting machine 15, a crushing and sorting apparatus may be used, in which a crusher and a sieving device are arranged, respectively.
The storage tank 17 is used for temporarily storing the municipal refuse W3, and various storage facilities such as a sealed tank and a building can be used. The waste incineration furnace 18 is usually provided in a municipal waste incineration apparatus, and the municipal waste incineration apparatus 1 further comprises a power generation facility provided with a boiler and heat for recovering heat from the exhaust gas. The receiving chamber 13 and the crushing sorter 15 are provided with an air supply passage 16 communicating with an incinerator 18, and the incinerator 18 can treat the exhaust gas of the receiving chamber 13 including the rotary kiln 14 and the crushing sorter 15 with the incinerator 18. The municipal waste W1 supplied to rotary kiln 14 is fermented in the rotary kiln without breaking the bags used for packaging the waste. When rotary kiln 14 rotates at a low speed, municipal refuse W1 is crushed and mixed, and the moisture content of refuse W1 is reduced due to the fermentation heat generated by aerobic fermentation. By rotating rotary kiln 14, the fermentation process may be performed for about 3 days, but the fermentation process may be performed for less than 3 days as long as the fermentation is performed and harmful microorganisms are killed.
