Description

Technical Field

[0001] The present invention belongs to the technical field of solid waste treatment, and specifically relates to a system and process method for the coordinated resource disposal of fly ash and multi-source solid waste by plasma melting. Background Art

[0002] Hazardous waste refers to solid and liquid waste that has one or more hazardous characteristics (such as corrosive, toxic, flammable, reactive and infectious) or is likely to harm the environment or human body and needs to be treated as hazardous substances. It mainly includes industrial hazardous waste and medical waste.

[0003] Fly ash mainly comes from the air pollutant purification equipment at the back of the waste incinerator. Because it contains high alkali metal chlorides, heavy metals, polychlorinated dioxins and furans, it is a hazardous waste. If the fly ash is not properly disposed, it will cause serious harm to the environment and human health. At present, plasma melting technology is internationally recognized as the "third generation" technology that completely disposes hazardous waste and can achieve harmless ultimate disposal. It has unparalleled environmental advantages and huge application prospects in the treatment of fly ash and other hazardous wastes. Plasma melting technology, through the high temperature, high humidity and high activity reaction environment provided by plasma, decomposes organic matter into clean small molecule inorganic matter, and realizes the cracking of dioxins. Fly ash and hazardous waste bottom slag are melted into glass slag by plasma, which realizes harmless disposal. The resource utilization of glass slag is the main means to realize the high value of waste incineration fly ash and hazardous waste bottom slag.

[0004] The existing fly ash plasma melting process often has the following problems: (1) The existing process generally directly transports the fly ash into the plasma furnace for treatment through the fly ash silo. Due to the high CaO content in the fly ash, the melting temperature is high, which in turn leads to high energy consumption; (2) Since the powdered fly ash is directly transported to the plasma furnace, secondary dust will occur on site, and after the powdered fly ash is treated by plasma melting, the plasma furnace will have the problem of difficult slag removal; (3) The proportion of SiO2 in the glass slag obtained by plasma furnace melting treatment is not appropriate, which affects the subsequent resource utilization of the glass slag; (4) Since the temperature of the flue gas at the outlet of the plasma furnace is too high, it is difficult to carry out the subsequent flue gas treatment system. Therefore, it is necessary to improve the existing fly ash treatment system and process, and propose a new treatment plan. Summary of the invention

[0005] In view of the above problems, the present invention provides a system and process method for the coordinated resource disposal of fly ash and multi-source solid waste by plasma melting, which solves the above technical problems existing in the existing fly ash plasma melting process.

[0006] The present invention proposes a method for resource utilization by plasma melting synergistic treatment of fly ash, coal ash and solid waste such as waste glass bottles, mainly adopting a plasma melting method. Fly ash and fly ash are general solid waste and hazardous waste respectively. The CaO content of fly ash is relatively high, resulting in a high melting temperature, and thus leading to high energy consumption; the content of acidic oxide SiO2 in fly ash is extremely high, and the content of Al2O3 also accounts for a large proportion. Therefore, the addition of fly ash can greatly change the ratio of the three oxides SiO2-Al2O3-CaO, which has a great influence on reducing the melting temperature of fly ash and the formation of the crystal phase of molten glass.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is: On the one hand, the present invention proposes a system for the coordinated resource disposal of fly ash and multi-source solid waste by plasma melting, comprising a fly ash silo, a fly ash silo, a binder storage tank, a material intermediate silo, a glass silo, a mixer, an extrusion molding granulator, a plasma furnace and a control center, wherein the outlets of the fly ash silo, the fly ash silo and the binder storage tank are respectively provided with a fly ash silo star-shaped ash unloading valve, a fly ash silo star-shaped ash unloading valve and a flow regulating valve, all of which are connected to the material inlet of the mixer, the material outlet of the mixer is connected to the inlet of the extrusion molding granulator, the material outlet of the extrusion molding granulator is connected to the inlet of the material intermediate silo after passing through a first material conveyor belt and a bucket elevator; the outlet of the material intermediate silo is connected to the second material conveyor belt, the outlet of the glass silo is connected to the third material conveyor belt, the discharge ports of the second material conveyor belt and the third material conveyor belt are both connected to the total feed screw, and the material outlet of the total feed screw is connected to the material inlet of the plasma furnace.

[0008] Furthermore, the binder storage tank is also provided with a binder delivery pump, and the fly ash silo star-shaped ash discharge valve, the fly ash silo star-shaped ash discharge valve, the binder delivery pump, the flow regulating valve, the second material conveying belt and the third material conveying belt are all electrically connected to the control center to achieve precise feeding control.

[0009] Furthermore, the upper part of the fly ash silo and the fly ash silo is set to a cylinder, and the lower part is set to a cone, and the cone angle of the cone is set to 35-60°; a fly ash silo vibrator and a fly ash silo vibrator are respectively provided on the cones of the fly ash silo and the fly ash silo, and the material is prevented from agglomerating and clogging by vibrating.

[0010] Furthermore, the material intermediate bin is provided with a material intermediate bin vibrator and a first electric regulating gate valve, and the glass material bin is provided with a glass material bin vibrator and a second electric regulating gate valve to prevent blockage and control the amount of material falling.

[0011] Furthermore, a component detection device is connected to the main feed screw to detect the components of the materials in the main feed screw, and the component detection device is an XRF detector. The component detection device will feedback and adjust through the control center according to the total components after the raw materials are mixed (i.e., the requirements within the formula range), if it exceeds the formula range, and then automatically adjust the feed flow of a single raw material or two raw materials to achieve automatic control function.

[0012] Furthermore, the plasma furnace is provided with a plasma torch, a bottom blowing spray gun and a top blowing spray gun. A slurry outlet channel is provided at the bottom of the plasma furnace, and the slurry outlet channel is connected to a water quenching tank. The water quenching tank is provided with a slag scooping machine and a cooling water circulation system, including a slag-water heat exchanger and a slag-water circulation pump.

[0013] Furthermore, a quenching tower is provided at the top outlet of the plasma furnace, a quenching spray gun is provided above the quenching tower, the quenching spray gun is connected to a process water tank and compressed air, the quenching tower outlet is connected to a bag-type dust collector, a compressed air inlet is provided on the top of the bag-type dust collector and is connected to an induced draft fan, and a two-stage discharge valve arranged in series is provided at the bottom of the bag-type dust collector.

[0014] On the other hand, the present invention proposes a process method for fly ash and multi-source solid waste plasma melting coordinated resource disposal, which is based on the fly ash and multi-source solid waste plasma melting coordinated resource disposal system as described above, and includes the following process steps: S1: fly ash, fly ash and binder are mixed and stirred in a certain proportion in the mixer controlled by the control center; S2: the material mixed in step S1 enters the extrusion molding granulator for granulation, and after granulation, it is transported to the material intermediate warehouse for temporary storage through the first material conveyor belt and bucket elevator; S3: crush the discarded glass bottles in advance and then transport them to the glass silo; the material intermediate silo drops the material to the second material conveyor belt, and the glass silo drops the material to the third material conveyor belt; under the control of the control center, control the ratio of the second material conveyor belt and the third material conveyor belt to control the ratio of the two materials and then enter the total feeding screw for mixed transportation; S4: The materials in the total feed screw are transported to the plasma furnace. Under the combined action of the plasma torch, auxiliary fuel gas and air, the furnace temperature is pre-set, the materials are melted, the organic matter undergoes gasification and combustion reaction, and the inorganic high melting point components gradually melt; after the slurry accumulates to a certain amount, it is led out of the plasma furnace bottom through the slurry outlet channel, and the slag is discharged by direct water quenching to obtain glassy solid slag, which enters the water quenching water tank, and the glassy solid slag is transported out for resource utilization by the slag remover; S5: The flue gas generated in the plasma furnace enters the quenching tower through the top outlet. The quenching spray gun sprays cooling process water and compressed air into the flue gas to cool it down. The cooled flue gas is dedusted by the bag filter and then discharged after the induced draft fan. After the bag filter of the bag filter sucks the dust, it is blown with compressed air. The fallen fly ash is collected in the ash hopper and discharged through the discharge valve and then sent back to the fly ash silo for reprocessing.

[0015] Preferably, the feed ratio in step S1 is: the amount of fly ash is 5% to 15% of the fly ash; the amount of discarded glass bottles is 5% to 10% of the fly ash; the amount of binder is 5% to 10% of the total amount of raw materials, the amount of water added is 15% to 20% of the total amount of raw materials, and the alkalinity of the raw materials after mixing is controlled at 1.1 to 1.6.

[0016] Preferably, the temperature of the lower part of the plasma furnace bottom is controlled at 1400°C to 1600°C; the temperature of the plasma furnace gas phase space is guaranteed to be 1200°C to 1300°C, and the residence time is 2 seconds to 3 seconds.

[0017] Compared with the prior art, the technical solution of the present invention has the following beneficial effects: (1) The present invention can realize the resource treatment of various solid wastes such as fly ash, coal ash and waste glass bottles, and perform pollution-free melting treatment to obtain a glass phase that can be subsequently recycled; (2) By mixing fly ash and fly ash, a low melting point mixture is formed, which promotes the low-temperature generation of the liquid phase, reduces the melting temperature, improves energy efficiency, saves processing costs, and forms a stable glass phase; (3) By adding a glass silo, the waste glass bottles can be recycled and the proportion of SiO2 in the slag can be further increased, which is more conducive to the subsequent recycling of glass residues; (4) After being mixed by the raw material mixer, the materials are sent to the extrusion molding granulator for granulation, replacing the previous process of directly sending the powdered materials into the plasma furnace. This makes it possible for the plasma furnace to avoid the problem of slag discharge difficulties, improves the material strength, and prevents secondary dust from occurring on site; (5) A quenching tower and other devices are installed at the top outlet of the plasma furnace to cool the outlet flue gas, so as to facilitate the subsequent flue gas treatment process.

[0019] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0020] like Figure 1 As shown, a fly ash and multi-source solid waste plasma melting coordinated resource disposal system, the main devices include fly ash silo 11, fly ash silo 12, binder storage tank 13, material intermediate silo 14, glass silo 15, mixer 2, extrusion molding granulator 3, plasma furnace 4 and control center 10. Through the coordinated disposal mode between fly ash and fly ash, through precise proportioning, and quantitative matching of binders, and the coordination between various devices, instrument valves and structures, the normal operation of the entire system is completed.

[0021] In the common existing fly ash plasma melting process, the fly ash is directly transported into the plasma furnace 4 through the fly ash silo 11. The newly added devices in this application are as follows: (a) a new fly ash silo star-shaped ash discharge valve 112 is added to accurately control the fly ash feed flow under the control of the control center 10, and a fly ash silo vibrator 111 is set to improve the metering accuracy of the fly ash silo star-shaped ash discharge valve 112; (b) a new fly ash silo 12 is added to provide a fly ash feeding channel, and a new fly ash silo star-shaped ash discharge valve 122 is added to accurately control the fly ash feed flow under the control of the control center 10, and a fly ash silo vibrator 111 is set to improve the metering accuracy of the fly ash silo star-shaped ash discharge valve 112. (c) A fly ash silo vibrator 121 is installed to improve the metering accuracy of the fly ash silo star-shaped ash discharge valve 122; (d) A binder storage tank 13 is added to provide a binder feeding channel, and a binder delivery pump 131 and a flow regulating valve 132 are added to accurately control the binder feeding flow under the control of the control center 10; (e) A new mixer 2 is added to mix the fly ash, fly ash and binder according to the formula ratio; (e) An extrusion molding granulator 3 is added to allow the raw materials to be granulated before entering the furnace for melting treatment, replacing the previous mode of directly feeding the fly ash powder into the furnace for treatment.

[0022] Specifically, in order to facilitate material unloading, the upper parts of the fly ash silo 11 and the fly ash silo 12 are set as cylinders, and the lower parts are set as cones; and a fly ash silo vibrator 111 and a fly ash silo vibrator 112 are respectively provided on the cones of the fly ash silo 11 and the fly ash silo 12 to prevent material agglomeration and clogging by vibrating.

[0023] Specifically, the cone discharge angle of the fly ash silo 11 and the fly ash silo 12 is set to 35°~60°. Too small or too large cone angles are prone to blockage of the discharge port. The fly ash silo vibrator 111 and the fly ash silo vibrator 112 can be set in multiple numbers and symmetrically distributed at equal angles around a circle. In the present application, they are set to 2 and symmetrically distributed.

[0024] The common fly ash plasma melting process directly transports the powdered fly ash to the high-temperature furnace. After the powdered fly ash is treated by plasma melting, the plasma furnace 4 will have the problem of difficult slag removal. In order to solve the above problem, the present invention adopts a fly ash granulation method to solve it. The embodiment of the present application adopts an extrusion molding granulator 3 to granulate a variety of raw materials. Preferably, the extrusion molding granulator 3 adopts an extrusion molding method to improve the strength and prevent secondary dust from occurring on site. The binder component in the present application is water glass (sodium silicate), and its main function is mainly for granulation.

[0025] The granulated material is conveyed to the material intermediate bin 14 for temporary storage via the first material conveying belt 31 and the bucket elevator 34. The material intermediate bin 14 is provided with a material intermediate bin vibrator 141 and a first electric regulating gate valve 142 to prevent blockage and control the amount of material falling.

[0026] In order to further increase the proportion of SiO2 and simultaneously dispose of solid wastes such as discarded glass bottles, the discarded glass bottles are crushed and transported to the glass silo 15. The glass silo 15 is provided with a glass silo vibrator 151 and a second electric regulating gate valve 152 to prevent blockage and control the amount of material falling.

[0027] The bottom discharges of the material intermediate bin 14 and the glass bin 15 are respectively provided with a second material conveying belt 32 and a third material conveying belt 33 , and both are provided with a weighing function, so as to control the proportion of the two under the control of the control center 10 .

[0028] In the present application, a component detection device 9 is also connected to the total feed screw 35, which is used to detect the components of the materials in the total feed screw 35. The component detection device 9 is an XRF detector. The component detection device 9 will feedback and adjust through the control center 10 according to the total components of the raw materials after mixing (i.e., the requirements within the formula range), if it exceeds the formula range, and then automatically adjust the feed flow of a single raw material or two raw materials to achieve an automatic control function.

[0029] The material is mixed in a certain ratio by the material conveying belt 32 and the third material conveying belt 33 and then conveyed to the plasma furnace 4 by the main feeding screw 35 for melting treatment.

[0030] refer to Figure 2 As shown, in the plasma furnace 4, the organic matter undergoes gasification and combustion reaction under the combined action of the plasma torch 41, the auxiliary fuel gas material and the air, and the inorganic high melting point components gradually melt. The plasma torch 41 and the bottom blowing gun 43 create a high temperature environment for the bottom of the plasma furnace 4. The temperature of the lower part of the furnace bottom is controlled at 1400℃~1600℃. A certain proportion of plasma gasifier (air) creates a high energy thermal environment through the plasma arc generated by the plasma torch 41, and the inorganic components are melted at the bottom of the furnace to form molten slurry. After the slurry accumulates to a certain amount, it is led out of the plasma furnace bottom through the slurry outlet channel, and the slag is discharged by direct water quenching to obtain a glassy solid slag, which enters the water quenching water tank 44. The water quenching water tank 44 is provided with cooling water for cooling the vitreous solid slag; the water quenching water tank 44 is provided with a slag scooping machine 441 for scooping the cooled vitreous solid slag and transporting it for resource utilization; in order to cool the normal operation, a cooling water circulation system is provided, which mainly includes a slag water heat exchanger 442 and a slag water circulation pump 443.

[0031] Specifically, the plasma torch 41 uses a water cooling device, which uses a deionized water pump 411 and a deionized water heat exchanger 412 for continuous cooling.

[0032] Since the plasma furnace 4 generates combustible gases (VOCs), volatile salts and some carried fly ash during operation, it has a great impact on the subsequent flue gas treatment, including partial combustion of combustible gases in the flue causing damage to subsequent equipment, and excessive VOCs gas emissions and fly ash emissions. To solve the above problems, a top-blowing lance 42 is provided. Under the combustion-supporting effect of the top-blowing lance 42, the combustion continues and is completely incinerated.

[0033] Specifically, a plurality of plasma torches 41 are arranged around the plasma furnace 4 , and in the present application, five plasma torches 41 are used.

[0034] Specifically, a plurality of top-blowing lances 42 are arranged around the plasma furnace 4 , and in the present application, five of them are used.

[0035] Specifically, a plurality of bottom blowing lances 43 are arranged around the plasma furnace 4 , and in the present application, four of them are used.

[0036] Preferably, in order to ensure that dioxins that may be generated in the flue gas produced by the thermal plasma reactor are completely decomposed at high temperature, the gas phase space temperature of the plasma furnace 4 is guaranteed to be 1200° C. to 1300° C., and the residence time is 2 seconds to 3 seconds.

[0037] Preferably, the combustion-supporting gas of the top-blowing lance 42 and the bottom-blowing lance 43 is natural gas. To ensure the combustion temperature, an oxygen-enriched preparation system 8 is provided to supply high-concentration oxygen to the top-blowing lance 42 and the bottom-blowing lance 43 .

[0038] Since the temperature of the flue gas at the outlet of the plasma furnace 4 is too high, the subsequent flue gas treatment system is difficult to operate. The present application is provided with a quenching tower 5, and a quenching spray gun 51 is provided above the quenching tower 5. The quenching spray gun 51 sprays cooling process water and compressed air into the flue gas to cool the flue gas. The source of the cooling process water is the process water tank 7 and the process water pump 71.

[0039] Specifically, a plurality of quenching spray guns 51 are provided at equal intervals on the top of the quenching tower 5 . In the present application, three quenching spray guns 51 are used.

[0040] The cooled flue gas is dedusted by the bag filter 6 and then discharged through the induced draft fan 61. After the bag filter 6 absorbs dust, it is blown with compressed air, and the fallen fly ash is collected in the ash hopper and discharged through the discharge valve 62 and then sent to the fly ash silo 11 for reprocessing.

[0041] Preferably, the discharge valve 62 is arranged in two stages in series to prevent the uncontrolled discharge of fly ash after the compressed air is sprayed.

[0042] Preferably, the quenching lance 51 rapidly cools the flue gas temperature from 1200-1300° C. to about 700-900° C. Too high a temperature is not conducive to the operation of the bag filter 6 and other equipment, while too low a temperature will cause the residual organic matter adsorbed on the fly ash surface to regenerate dioxins.

[0043] The recipe requirements are as follows: (1) In terms of alkalinity, the alkalinity of several raw materials is required to be controlled at 1.1~1.6 after mixing. The specific raw material formula is as follows: the amount of fly ash is 5%~15% of fly ash, and the amount of discarded glass bottles is 5%~10% of fly ash.

[0044] (2) In terms of calorific value, the calorific value of several raw materials after mixing is required to be 300~500kJ / kg. At this time, the system processing capacity can be increased by 70%. The specific raw material formula is as follows: Formula 1: Add petroleum coke to the plasma furnace at a ratio of 5% to 10%, and the ratio of natural gas to fly ash is 100 to 150 m 3 / t; Formula 2: Replace natural gas with acetylene gas with a higher calorific value, with a usage ratio of 70-110 m 3 / t.

[0045] During the granulation process, the ratio of binder to raw material is 5%~10%, and the ratio of added water to raw material is 15%~20%.

[0046] In summary, the technical solution of the present invention can realize the resource treatment of various solid wastes such as fly ash, coal ash and waste glass bottles, carry out pollution-free melting treatment, and obtain a glass phase that can be subsequently utilized as a resource; by mixing coal ash and fly ash, a low melting point mixture is formed, which promotes the low-temperature generation of the liquid phase, reduces the melting temperature, improves energy efficiency, saves processing costs, and forms a stable glass phase at the same time; by adding a glass material bin, the resource treatment of waste glass bottles is realized, and the proportion of SiO2 in the slag is further increased, which is more conducive to the subsequent resource utilization of glass residues; after mixing in a raw material mixer, the materials enter an extrusion molding granulator for granulation treatment, replacing the previous process of directly entering a plasma furnace with powdered materials, so that the plasma furnace will not have the problem of slag discharge difficulties, and the material strength is improved to prevent secondary dust on site; a quenching tower and other devices are arranged at the top outlet of the plasma furnace to cool the outlet flue gas, which is convenient for the subsequent flue gas treatment process.

[0047] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
