Description

Waste incineration fly ash solidification treatment system

Technical Field

The utility model relates to a waste incineration flying dust treatment facility field, concretely relates to waste incineration flying dust solidification processing system.

Background

The household garbage incineration has the advantages of obvious volume reduction, obvious quantity reduction, obvious resource recycling and the like, and is generally concerned at home and abroad. The domestic garbage is easy to generate secondary pollution by burning, and the burning fly ash is a main carrier of the secondary pollution. The incineration fly ash refers to that fine particulate matters float in flue gas in the incineration process of household garbage and enter a flue gas purification system along with the flue gas, lime and active carbon are required to be added in the flue gas purification process, the lime and the active carbon are collected by a dust collector, meanwhile, a part of fine particulate matters are settled at the bottom of a flue and a chimney, and the captured and settled fine particulate matters are called incineration fly ash. The chemical components of the incineration fly ash comprise Cl, Ca, K, Na, Si, Al, O and other elements, and the main chemical components are CaO, SiO2, Al2O3 and Fe2O 3. In addition, the incineration fly ash often contains heavy metals with high concentration, such as Hg, Pb, Cd, Cu, Cr, Zn and the like, the heavy metals mainly exist in the form of aerosol small particles and are enriched on the surfaces of fly ash particles, the incineration fly ash has stronger migration capability and bioavailability, and if the heavy metals are improperly disposed and enter the environment, serious and long-term secondary pollution is caused to the human health and the ecological environment, so the incineration fly ash needs to be subjected to stabilization and harmless treatment. The treatment method for fly ash incineration currently used in China is chelation curing, the fly ash chelation curing technology has simple process and low treatment cost, and the fly ash chelation curing technology is more and more commonly applied to harmless treatment of waste incineration fly ash.

However, most of the existing treatment methods adopt a horizontal double-shaft stirrer as chelating equipment, and the detection qualification rate of the concentration of the heavy metal leachate pollutants in the fly ash treated by the process is generally lower than 60 percent nationwide; and because the particle size of the fly ash is small, a large amount of flying dust can be generated in the process of treatment and transportation and is adhered to treatment equipment and workshops. Due to strong alkalinity and high chloride ion content of the fly ash, a large amount of dust can cause severe working environment on site, severe equipment corrosion and damage to respiratory tracts, lungs and skins of contacters.

SUMMERY OF THE UTILITY MODEL

In order to solve the processing procedure that prior art exists in the raise dust many, detect the low scheduling problem of qualification rate after handling, the application provides a waste incineration fly ash solidification processing system.

In order to achieve the purpose, the technical scheme adopted by the application is as follows:

a waste incineration fly ash solidification treatment system is used for carrying out innocent treatment on fly ash and comprises a feeding group and a stirring group, wherein the fly ash enters the stirring group through the feeding group and is mixed and stirred with a solidification agent to form an intermediate product; also included is a processing group for compressing and dividing the intermediate product into a plurality of cured products.

The method for solidifying the garbage fly ash in the prior art mainly comprises three methods, namely cement solidification, chemical agent stabilization and melting solidification. Among them, the melt-solidification method has minimal environmental pollution, but requires high-temperature melting of fly ash, which is expensive and not widely used.

The cement solidification method and the chemical agent stabilization method are different in the used condensate, wherein in the cement hydration process, heavy metal finally stays on the surface of hydrated silicate colloid C-S-H formed by cement solidification in the form of hydroxide or complex through various modes such as adsorption, chemical absorption, sedimentation, ion exchange, passivation and the like; the latter is to react the easily soluble harmful metals in the fly ash with the complexing groups in the chemical agent by the chelation of the chemical agent to form a stable complex to prevent the leaching of the harmful components. But the two processes are similar, and the fly ash and the solidified substance are mixed and stirred to inhibit the percolation and precipitation of heavy metals in the fly ash, and then the mixture is piled up to form an adhesive soil block, and finally the soil block is buried. However, when the fly ash forms lumps, the fly ash is likely to be broken due to improper mixing ratio of fly ash and solidified material, or due to evaporation of water, and the lumps may be broken due to internal stress due to excessive volume.

According to the scheme, after the fly ash and the curing agent are mixed and stirred to form an intermediate product, the intermediate product is compressed and divided by the processing group. The compression action makes the intermediate product more compact, and reduces the contact area between the treated matter and the outside, thereby greatly reducing the dissolving-out concentration of harmful substances, avoiding the segregation of various components and ensuring the stability of the cured product in the nature; the dividing treatment reduces the occupied space and prevents the cracking after the agglomeration.

It is worth mentioning that the present solution is applicable both to cement setting processes and to chemical agent stabilization processes. When cement is used as a curing agent, the stirring group is utilized to fully mix the cement and the fly ash, and the chelating agent is utilized to increase the contact area of the fly ash and the chelating agent so as to fully chelate the fly ash.

Further, the processing group comprises a granulating mechanism connected with the stirring group, and the granulating mechanism discharges the prepared solidified finished product outwards.

The granulation mechanism produces the intermediate product into granules, and it is worth mentioning that, according to the existing granulator, in the granulation process, the granulator itself has a certain compression effect in order to form granules with a certain shape from the intermediate product.

It is worth noting that in order to complete the granulation process of the intermediate product, it is necessary to ensure the moisture content of the intermediate product when mixing the fly ash into the intermediate product, so that the water content can be increased appropriately without fear of too high a water content, since the compression process can squeeze out excess water. Compared with the prior art that the mixing proportion and the water content must be strictly controlled so as not to cause the fragmentation of a cured finished product or the precipitation of harmful metals, the scheme ensures that the added curing agent has certain fault tolerance.

Further, the processing group comprises a bagging mechanism for intensively packaging the solidified finished products. And the solidified finished product is transported to be beneficial to subsequent transportation to a landfill site.

Further, the stirring group comprises a stirring mechanism and a cutting mechanism which are used for uniformly stirring the fly ash mixed with the solidified medicament to form an intermediate product, and the axis of the stirring mechanism is intersected with the axis of the cutting mechanism.

In the prior art, the fly ash solidification treatment mainly uses a horizontal double-shaft stirrer to stir the garbage fly ash, the chelating agent and the like, and the double-shaft stirrer mainly comprises two symmetrical and synchronously rotating spiral shafts. However, since the screw shaft has a large outer surface area and is likely to adhere to a humidified material, it is necessary to periodically clean the accumulated material on the screw shaft.

In this scheme, flying dust and solidification medicament mix and bond into the granule, and the granule that forms rubs mutually under rabbling mechanism's effect and collides, constantly growing, and the cutting mechanism who sets up in the stirring storehouse cuts the granule, makes by the continuous repeated bonding-process of smashing of stirring to make the heavy metal ion in the flying dust fully contact with the medicament and chelate, and the crossing fully mixed contact that can further guarantee flying dust and solidification medicament of rabbling mechanism and cutting mechanism axis guarantees the chelation effect.

Furthermore, the stirring group also comprises a stirring bin filled with fly ash and solidified agents, and the action parts of the stirring mechanism and the cutting mechanism are arranged in the stirring bin.

The stirring bin is a main place where stirring and mixing actions occur, the action parts of the stirring mechanism and the cutting mechanism rotate in the stirring bin to play a role, and the driving parts of the stirring mechanism and the cutting mechanism are fixed outside the stirring bin.

Further, a first closed space is arranged between the feeding group and the stirring group, and the first closed space is communicated with a negative pressure mechanism for intensively treating the fly ash leaked from the communicated part of the feeding group and the stirring group; the negative pressure mechanism forms a negative pressure state in the first closed space.

As the fly ash enters the agitated bank from the feed bank, there are instances where a small amount of fly ash escapes from the junction. This scheme sets up airtight space at the junction of feeding group and stirring group, prevents that the flying dust that overflows from forming the raise dust, not only adheres to and influences the normal operating of equipment on the equipment, still can cause the injury to contacter's respiratory tract, lung and skin. Meanwhile, the first closed space is connected by the negative pressure mechanism, so that the fly ash leaves the first closed space under the action of negative pressure, and the cleanness of the joint of the feeding group and the stirring group is ensured.

It is worth to say that the negative pressure mechanism comprises a dust hood arranged in the first closed space, and a pipeline connecting the dust hood and the negative pressure mechanism, wherein a dust removal device is arranged on the pipeline. The dust hood enlarges the contact area of the negative pressure mechanism in the first closed space and enhances the dust removal effect of the negative pressure mechanism. The dust removal device is arranged on a pipeline between the dust collection cover and the negative pressure machine, and is used for filtering or adsorbing dust in air pumped out by the negative pressure machine, so that the air containing the dust is prevented from being discharged by the negative pressure machine to cause air pollution.

Furthermore, a second closed space is covered outside the structure of the stirring group except the connecting part of the treatment group and the feeding group, and a positive pressure state is formed in the second closed space through a positive pressure mechanism communicated with the second closed space.

The stirring group has no flying ash escaping condition except the structure of the connection part of the treatment group and the feeding group, but needs to prevent the flying ash escaping and the dust in the air from adhering, so that the second closed space is in a positive pressure state, the dust is prevented from entering, and the cleanness and the normal operation of equipment such as a driving motor of a stirring mechanism and a cutting mechanism in the stirring group are ensured.

Further, the feeding group comprises an ash bucket with internal fly ash naturally falling and accumulating, and the lower end of the ash bucket is communicated with the stirring group; a weighing module is arranged in the ash hopper, and a discharge valve is arranged between the ash hopper and the stirring group; and after the fly ash on the weighing module reaches a single weighing threshold value, the single unloading is carried out by opening the unloading valve.

When the solidification treatment is realized by mixing the fixed medicament and the fly ash, key influencing factors are medicament mixing proportion and stirring effect. An ash hopper and a weighing module are arranged in the feeding group, after the fly ash is added into the ash hopper by an operator, the weighing module displays the weight of the fly ash in real time, when the weight reaches a preset value, feeding is stopped, a discharging valve is opened, and the fly ash in the ash hopper naturally falls into the stirring group. The scheme can weigh the fly ash to be solidified in the equipment, avoids the problems of weight reduction and the like caused by adding the fly ash into the equipment after weighing, reduces the proportion error during mixing and ensures the solidification effect.

Further, the stirring device also comprises a medicament adding group for adding a curing medicament into the stirring group.

Further, the medicament adding group comprises a metering mechanism, a pumping mechanism and an atomizing mechanism which are connected in sequence, and the atomizing mechanism is arranged in the stirring group.

The scheme further optimizes the adding mode of the solidified medicament, ensures the accuracy of the weight or concentration of the medicament by using a special metering mechanism, realizes automatic medicament adding by a pumping mechanism, and reduces manual operation. The stirring group is internally provided with an atomizing mechanism for atomizing the medicament, and the solidified medicament is liquid prepared by using the medicament, such as diluted solution formed by chelating agent and water according to a certain proportion or liquid formed by cement, lime powder and water according to a certain proportion. The liquid curing agent is atomized and then uniformly added into the stirring group to be mixed with the fly ash, so that the full and uniform contact between the curing agent and the fly ash can be ensured, and the curing effect is further ensured.

The utility model has the advantages that:

(1) the heavy metal chelating effect is good: the fly ash is continuously stirred, bonded and smashed in the granulation process, so that heavy metal ions in the fly ash are fully contacted with the curing agent, and the chelation effect is ensured. Meanwhile, the dissolution of heavy metal ions can be further reduced by the solidification effect of the calcium carbonate. Thereby ensuring the chelating effect on heavy metal ions in the fly ash.

(2) The stability of the treated substance is good: the treated fly ash is made into compact particles, so that the contact area between a treated object and the outside is reduced, the dissolution concentration of harmful substances is greatly reduced, the segregation of various components can be avoided, and the stability of the treated object in the nature is ensured. Meanwhile, the generated calcium carbonate is almost insoluble in water and has good stability in nature, so that harmful substances in the fly ash can be stably solidified by the calcium carbonate for a long time.

(3) The field environment is improved: the particle size of the prepared particles is increased, so that the generated dust is greatly reduced, and the formed calcium carbonate can solidify ammonia gas, chloride ions and the like, thereby ensuring the health of the field working environment and the contact persons.

(4) And (3) saving a landfill site: after the fly ash is extruded and granulated, the internal pores of the granules are reduced, the bulk density is increased, and the landfill site can be saved.

Example 1:

a waste incineration fly ash solidification treatment system as shown in fig. 1-2, which is used for performing harmless treatment on fly ash, and comprises a feeding group 1 and a stirring group 2, wherein the fly ash enters the stirring group 2 through the feeding group 1 and is mixed and stirred with a solidification agent to form an intermediate product; also included is a processing group for compressing and dividing the intermediate product into a plurality of cured products. The processing group comprises a granulating mechanism 3 connected with the stirring group 2, and the granulating mechanism 3 discharges the prepared solidified finished product outwards.

The working principle is as follows:

the curing agent is one of the key factors of the fly ash curing treatment, and the components of the curing agent determine the fly ash curing method, for example, the cement curing method is used as the curing agent; lime, fly ash, cement kiln dust, slag of a melting furnace and the like are used as curing agents, and the lime curing method is a lime curing method for realizing fly ash curing treatment by utilizing a wave cable reaction; the use of chelating agents as curing agents is drug stabilization. It is worth noting that, regardless of which solidification agent is used, a certain amount of water or other liquid must be added to achieve the fly ash solidification process.

The preferred use of the present invention is for fly ash solidification treatment using a medicament stabilization process. Specifically, chelating agent is used for preparing chelating diluent, fly ash and the chelating diluent are mixed and stirred in the stirring group 2, the fly ash is wetted by the chelating agent diluent, so that the fly ash particles generate adhesive force, the particles are mutually bonded into particles under the action of liquid bridging, and the formed particles continuously rub and collide with each other in the stirring process and continuously grow to form an intermediate product. And then the processing group compresses the intermediate product to make the intermediate product more compact, and then cuts the intermediate product to form a final cured product.

It should be noted that the granulation unit 3 is preferably used as a main unit for performing the compression and division processing in this embodiment. The granulation process of the granulation unit 3 is as follows, and the intermediate product that is not originally formed enters the granulation unit 3 from the stirring group 2, and is extruded into smaller granules after being compressed by the granulation unit 3. From the working principle of the existing granulator, the granulator plays a role in compression and division.

Example 2:

in this embodiment, a treatment group is further optimized and defined based on embodiment 1.

On the basis of example 1, the processing group comprises a bagging mechanism 4 for collectively packaging the cured product.

The working principle is as follows:

after the intermediate product enters a processing group to form a cured finished product, the cured finished product after being compressed and divided is packaged in a centralized way by using a bagging mechanism 4. In one example shown in fig. 1, the bagging mechanism 4 is connected to the output of the pelletizing mechanism 3.

It should be noted that, as shown in fig. 4, a curing process is provided, the bagged cured products are generally stacked in a curing workshop for curing. Because the fly ash contains a certain amount of calcium oxide, the calcium oxide in the fly ash contacts with water to form calcium hydroxide when the fly ash and the solidifying agent are stirred and mixed. During the maintenance process, the calcium hydroxide absorbs carbon dioxide in the air to generate carbonation reaction, calcium carbonate is generated, and the calcium carbonate can solidify harmful substances in the fly ash, so that the precipitation of the harmful substances is further reduced. Meanwhile, the solid phase volume of the calcium carbonate is slightly larger than that of the calcium hydroxide, so that the structure of the prepared particles is more compact, and the hardness of the prepared particles is increased.

Example 3:

in this embodiment, the stirring group 2 is further optimized and defined based on the above embodiments.

As shown in fig. 3, the stirring group 2 includes a stirring mechanism 202 and a cutting mechanism 203 which together stir the fly ash mixed with the solidified agent uniformly to form an intermediate product, and the stirring mechanism 202 intersects with the axis of the cutting mechanism 203. The stirring group 2 further comprises a stirring bin 201 filled with fly ash and solidified agents, and the action components of the stirring mechanism 202 and the cutting mechanism 203 are arranged in the stirring bin 201.

The working principle is as follows:

the main functional components of the stirring group 2 are a stirring mechanism 202 and a cutting mechanism 203, and during stirring, the fly ash and the solidified reagent are in the stirring bin 201, and the action components (such as stirring blades) of the stirring mechanism 202 rotate to make the fly ash and the solidified reagent continuously contact and harden into large particles. Then under the action of the action part of the cutting mechanism 203, the grown particles are broken up and then stirred and continuously mixed with the curing agent, so that the heavy metal ions in the fly ash are fully contacted and chelated with the curing agent. The axes of the stirring mechanism 202 and the cutting mechanism 203 are crossed, so that the stirring direction is different from the cutting direction, the full mixing contact of the fly ash and the solidified agent is ensured, and the chelating effect is ensured.

Example 4:

the present embodiment is further optimized and limited based on the above embodiments.

As shown in fig. 1, a first closed space 6 is provided between the feeding group 1 and the stirring group 2, and the first closed space 6 is communicated with a negative pressure mechanism 8 for intensively treating fly ash leaked from a communication part between the feeding group 1 and the stirring group 2; the negative pressure mechanism 8 forms a negative pressure state inside the first closed space 6. A second closed space 7 is covered outside the structure of the stirring group 2 except the connection part with the processing group and the feeding group 1, and a positive pressure state is formed in the second closed space 7 through a positive pressure mechanism communicated with the second closed space 7.

The working principle is as follows:

when the fly ash moves from the feeding group 1 to the stirring group 2, the fly ash may leak from the connection between the feeding group 1 and the stirring group 2 because the particle size of the fly ash is small. A first closed space 6 is arranged at the joint of the feeding group 1 and the stirring group 2, a negative pressure mechanism 8 forms a negative pressure state in the first closed space 6, and leaked fly ash is pumped out of the first closed space 6 by the negative pressure mechanism 8, so that the fly ash is prevented from being accumulated in the first closed space 6 to corrode the surface of equipment and influence the work of the equipment.

In addition, the second enclosed space 7 is connected with a positive pressure mechanism, the positive pressure mechanism inputs clean air into the second enclosed space 7, and after a positive pressure state is formed in the second enclosed space 7, external dust cannot enter, so that pure gas is always overflowed in the second enclosed space 7.

Example 5:

in this embodiment, based on the above embodiments, the feeding set 1 is further optimized and defined.

As shown in fig. 2, the feeding group 1 comprises an ash bucket 102 with the internal fly ash naturally falling and accumulating, and the lower end of the ash bucket 102 is communicated with the stirring group 2; a weighing module 101 is arranged in the ash hopper 102, and a discharge valve 103 is arranged between the ash hopper 102 and the stirring group 2; and after the fly ash on the weighing module 101 reaches a single weighing threshold value, the discharge valve 103 is opened for single discharge.
