Description

Fly ash mixing device {Fly ash mixer}

The present invention relates to a fly ash mixing device, and more specifically, to a fly ash mixing device that can stabilize heavy metals without leaking fly ash to the outside.

Unless otherwise indicated herein, the matters described in this identification are not prior art to the claims of this application, and are not acknowledged to be prior art by being described in this identification.

In general, waste such as various wastes generated at home or industrial sites are disposed of by being buried in a landfill or incinerated in an incinerator. Incinerator ash generated after incineration of waste is largely divided into bottom ash, which is discharged to the bottom of the incinerator, and fly ash, which is contained in combustion gas and collected and removed. Floor ash has a relatively low concentration of heavy metals harmful to the human body, but fly ash has a high concentration of heavy metals. Since fly ash contains a lot of heavy metals, it is buried in managed landfills in a state in which the heavy metals are removed or stabilized to prevent the heavy metals from leaching out.

There are two methods of processing fly ash: chemical stabilization, which involves chemical stabilization, and thermal stabilization, which involves thermal stabilization. Chemical stabilization methods include cement solidification methods, chemical treatment methods, and acid extraction methods, and thermal stabilization methods include melting methods.

Among the chemical stabilization methods, there is a method of chemical treatment that mixes an acidic heavy metal stabilizer with water for mixing or dilution of fly ash and reacts with the heavy metal in the fly ash to create an insoluble heavy metal compound. Heavy metal stabilizers used to stabilize heavy metals in fly ash include nitrogen and sulfur-based organic chelates. In the heavy metal stabilization treatment process, a certain amount of fly ash is input into the fly ash mixing device 10, and the heavy metal stabilizer and water added according to the amount of fly ash are sufficiently mixed with the input fly ash to stabilize the heavy metals so that they do not elute, and then the heavy metal is stabilized. Treated fly ash is discharged from the fly ash mixing device.

However, during the heavy metal stabilization process of fly ash, due to the nature of fly ash having a light specific gravity, fly ash may fly or float in the internal space of the fly ash mixing device. Such fly ash leaks to the outside through gaps between parts of the fly ash mixing device and can be inhaled into the worker's respiratory tract. Fly ash containing heavy metals can cause fatal harm to the health of workers.

Fly ash not only leaks from inside the fly ash mixing device, but is also generated when fly ash transported from the incinerator is input through the inlet of the fly ash mixing device. Fly ash is inputted with a hopper or fly ash supply pipe connected to the inlet of the fly ash mixing device by bolting, etc. There are gaps in the bolting joints, and fly ash leaks through these gaps.

Conventional technologies (Korea Patent Publication No. 10-2015-0076536, published on July 7, 2015/Korea Patent Registration No. 10-2206601, registered on January 18, 2021) mix fly ash, heavy metal stabilizer, and water uniformly. The focus is on technologies that improve efficiency or the convenience of replacing mixing paddles, and technologies that prevent or recover fly ash leakage are rare.

Therefore, there is a need for a fly ash mixing device that can prevent fly ash from leaking to the outside during the heavy metal stabilization process of fly ash and can recover fly ash that has already leaked to the outside.

Republic of Korea Patent Publication No. 10-2015-0076536 (published on July 7, 2015) Republic of Korea Patent No. 10-2206601 (registered on January 18, 2021)

As shown in these drawings, the fly ash mixing device 10 of the present invention mixes fly ash containing heavy metals among wastes such as various wastes generated at home or industrial sites with a heavy metal stabilizer such as a chelate and water, thereby removing the fly ash from the fly ash. This is a heavy metal stabilization treatment that prevents heavy metals from leaching. At one end, an inlet 110 through which fly ash is introduced is provided, a mixing space 121 is provided inside where the injected fly ash is mixed with a heavy metal stabilizer, and at the other end, a heavy metal stabilization agent is provided. A casing 100 provided with an outlet 130 through which fly ash treated with heavy metal stabilization by fire is discharged, a pair of rotor shafts 210 installed in the mixing space 121 and rotating in opposite directions, and a rotor A plurality of paddle panels 220 radially fixed to the shaft 210 and installed at a predetermined distance along the longitudinal direction of the rotor shaft 210, and a mixing paddle coupled to one end of the paddle panel 220 The rotor unit 200 including (230), the drive unit 300 installed on one side of the casing 100, and coupled to the rotor shaft 210 to rotate the rotor shaft 210, are installed on the casing 100. It includes a spray unit 400 that sprays water and gas into the inner space 120 of the casing 100 so that the flying ash floating in the inner space 120 of the casing 100 settles. In addition, the present invention is installed in the casing 100 at a predetermined distance from the water spray nozzle 410 and the gas spray nozzle 430, and sucks fly ash floating in the internal space 120 of the casing 100. It may further include a first fly ash suction unit 500 and a second fly ash suction unit 600 installed adjacent to the inlet 110 to suction fly ash floating in the external space of the casing 100. In addition, a control unit (not shown) that controls the rotor unit 200, the drive unit 300, the spray unit 400, the first fly ash suction unit 500, and the second fly ash suction unit 600 may be further included. .

Since the present invention is characterized in that it is possible to prevent leakage of fly ash from the fly ash mixing device 10, the contents related to this are described in detail, and other contents related to the function and structure of the general fly ash mixing device 10 will be briefly explained.

The casing 100 serves to provide a space where fly ash is mixed with a heavy metal stabilizer and water, and may be formed as a long hollow tank. The internal space 120 of the casing 100 can be divided into a mixing space 121 where fly ash is mixed with a heavy metal stabilizer and water, and a non-mixing space 122 other than the mixing space 121. A rotor unit 200 may be installed in the mixing space 121, and a spray unit 400 and a first fly ash suction unit 500 may be installed in the non-mixing space 122.

Fly ash transported from the incinerator is input into the input port 110 provided at one end of the casing 100. Fly ash is temporarily stored in a storage such as a hopper or storage tank before being treated for heavy metal stabilization, and the fly ash supply pipe 20 connected to this storage is connected to the inlet 110 of the casing 100. The temporarily stored fly ash is injected into the casing 100 through the fly ash supply pipe 20 and the inlet 110 of the casing 100 after the fly ash supply pipe 20 and the casing 100 are bolted. The fly ash is mixed with the heavy metal stabilizer and water by the rotor unit 200 installed in the mixing space 121 and is transferred to the outlet 130 provided at the other end. The fly ash that has reached the other end has undergone heavy metal stabilization treatment to prevent heavy metals from leaching out, and is discharged out of the casing 100 through the discharge port 130.

The rotor unit 200 installed in the mixing space 121 directly mixes fly ash, heavy metal stabilizer, and water within the mixing space 121 and transports them to the outlet 130 of the casing 100. A pair of rotor shafts 210 rotating in opposite directions, a plurality of paddle panels 220 installed along the longitudinal direction of the rotor shaft 210, and one end of the paddle panels 220 are combined to collect fly ash. It may include a mixing paddle 230 for mixing.

The rotor shaft 210 forms a pair and is arranged side by side adjacent to each other while crossing the mixing space 121 along the longitudinal direction of the casing 100. That is, the rotor shaft 210 consists of a first rotor shaft 210 and a second rotor shaft 210. When the first rotor shaft 210 rotates clockwise or counterclockwise, the second rotor shaft 210 rotates counterclockwise or clockwise. When the first rotor shaft 210 and the second rotor shaft 210 rotate in directions facing each other, fly ash to which a heavy metal stabilizer and water have been added are formed on the first rotor shaft 210 and the second rotor shaft 210. Since they are mixed while gathering in between, mixing efficiency can be improved. The paddle panel 220 is formed to be inclined with respect to the rotor shaft 210 so that the fly ash is mixed and transported to the discharge port 130. The mixing paddle 230 coupled to one end of the paddle panel 220 may be formed in a plate shape with a predetermined area. Additionally, in order to increase the mixing efficiency of fly ash, the mixing paddle 230 may be formed in a twisted shape so that one end and the other end have a twist angle with respect to each other. Additionally, as shown in FIG. 6, the mixing paddle 230 can form a detachable coupling structure with the paddle panel 220. The mixing paddle 230 may be worn or damaged due to continuous contact friction or collision with the fly ash when mixing the fly ash. Accordingly, a detachable coupling structure such as bolting may be formed between the mixing paddle 230 and the paddle panel 220 so that only the mixing paddle 230 that is worn or damaged can be replaced.

The driving unit 300 installed on one side of the casing 100 serves to provide rotational driving force to the rotor unit 200 and may be composed of a motor 310, a reducer 320, etc. The motor 310 and the reducer 320 of the driving unit 300 are coupled to the rotor shaft 210 and rotate the rotor shaft 210.

The spray unit 400 installed in the casing 100 sprays water and gas onto the fly ash floating in the internal space 120 of the casing 100 and serves to cause the fly ash to settle together with the water. ) is preferably installed in the upper part of the internal space 120. This is because the mixing space 121 is located in the lower part of the internal space 120 of the casing 100. The sprayed water combines with the floating fly ash and settles together with the fly ash into the mixing space 121, and the gas pulverizes the sprayed water into fine-sized particles. This is because the finer the particle size of the sprayed water, the easier it is to combine with floating fly ash. Air is generally used as the gas, and depending on the type of components contained in the fly ash, nitrogen, argon gas, etc. may be used.

The spray unit 400 is formed to protrude on the inner surface of the casing 100 and is connected to the water spray nozzle 410, which sprays water into the inner space 120 of the casing 100. A water supply pipe 420 for supplying water, a gas that protrudes from the inner surface of the casing 100 and is arranged to spray gas in the same direction as the water spray nozzle 410 and installed adjacent to the water spray nozzle 410. It may include an injection nozzle 430 and a gas supply pipe 440 connected to the gas injection nozzle 430 to supply gas. The water spray nozzle 410 may be installed in the non-mixing space 122 rather than the mixing space 121 of the internal space 120 of the casing 100. The water spray nozzle 410 may be installed close to the inlet 110 where there is a relatively large amount of floating fly ash. A plurality of water spray nozzles 410 may be installed depending on the amount of fly ash input, and a plurality of water spray nozzles 410 may be installed in a row along the longitudinal or width direction of the casing 100. Since the amount of fly ash floating increases when the fly ash is introduced, it is preferable that the water spray nozzles 410 are centrally placed close to the inlet 110. As shown in FIG. 7, the gas spray nozzle 430 is installed adjacent to the water spray nozzle 410, and pulverizes the water sprayed from the water spray nozzle 410 into a fine size. In order for the sprayed water to collide with the gas and be finely pulverized, the gas spray nozzle 430 is preferably located behind the water spray nozzle 410. That is, the water injection opening 411 through which the water of the water injection nozzle 410 is sprayed is located ahead of the gas injection opening 431 through which the gas of the gas injection nozzle 430 is sprayed. Due to this positional relationship, the gas sprayed from the gas spray nozzle 430 may collide with the water sprayed behind the sprayed water, pulverizing the water into a fine size. The water supply pipe 420 and the gas supply pipe 440 are installed outside or inside the casing 100 and can supply water and gas to the water spray nozzle 410 and the gas spray nozzle 430, respectively.

The first fly ash suction unit 500, which is installed in the casing 100 and spaced apart from the water spray nozzle 410 and the gas spray nozzle 430 at a predetermined distance, floats in the internal space 120 of the casing 100. A first suction port 510, which serves to suck in fly ash, is installed inside the casing 100 and through which fly ash floating in the internal space 120 of the casing 100 is sucked, and a first suction port 510. A first suction pipe 520 that is connected to and guides the fly ash sucked in the inner space 120 of the casing 100, and a first suction pipe 520 connected to the first suction pipe 520 and floating in the inner space 120 of the casing 100. It includes a first blower 530 that sucks in fly ash, guides it, and discharges it, and a first supply pipe 540 that is connected to the first blower 530 and supplies the fly ash discharged from the first blower 530 to the gas supply pipe 440. can do.

The first suction port 510 serves to suction fly ash floating in the internal space 120 of the casing 100, and may be formed on the inner surface of the casing 100 or protruding from the inner surface. The first intake port 510 may be formed of a pipe or duct and may be installed to face the mixing space 121 of the casing 100. The first inlet 510 may be located near the inlet 110 of the casing 100 or elsewhere, but is spaced apart from the water spray nozzle 410 and the gas spray nozzle 430 toward the outlet 130 of the casing 100. It is desirable to be located. When the first inlet 510 is located away from the water spray nozzle 410 and the gas spray nozzle 430 toward the outlet of the casing, most of the floating fly ash settles and a small amount of the remaining fly ash is in the first inlet 510. Since suction is performed, the open portion of the first suction port 510 may not be blocked. A plurality of first suction ports 510 may be installed depending on the amount of fly ash input, and a plurality of first suction ports 510 may be installed in a row along the longitudinal or width direction of the casing 100. The first suction pipe 520 connected to the first suction port 510 serves to guide the fly ash sucked from the internal space 120 of the casing 100 through the first suction port 510 to the first blower 530. By doing so, it is installed inside or outside the casing 100 and connected to the first blower 530.

One end of the first supply pipe 540 is connected to the first blower 530, and the other end is connected to the gas supply pipe 440. Accordingly, the fly ash floating in the internal space 120 of the casing 100 goes through a process of being sucked in from the internal space 120 of the casing 100 and discharged into the internal space 120 of the casing 100. Through this process, the floating fly ash settles with water and may not leak out of the casing 100. In addition, an opening and closing device (not shown) such as a damper or valve that opens and closes the flow path of the first supply pipe 540 will be installed at the other end of the first supply pipe 540 adjacent to the area connected to the gas supply pipe 440. You can. The switch (not shown) can control the amount of air containing fly ash supplied from the first supply pipe 540 to the gas supply pipe 440.

The second fly ash suction unit 600 installed adjacent to the inlet 110 serves to suck in fly ash floating in the external space of the casing 100, and as shown in FIG. 7, the second fly ash suction unit 600 is installed adjacent to the inlet 110. can be installed in Since fly ash leaks through the gap around the inlet 110 when it is injected, it is preferable that the second fly ash suction unit 600 is installed around the inlet 110. The second fly ash inlet 600 is installed outside the casing 100 and connected to the second inlet 610, through which fly ash floating in the external space of the casing 100 is sucked, and the second inlet 610. a second suction pipe 620 that guides fly ash sucked in from the external space of the casing 100, and a second suction pipe 620 connected to the second suction pipe 620 to suck in and guide fly ash floating in the external space of the casing 100 and discharge it. 2 It may include a blower 630 and a second supply pipe 640 that is connected to the second blower 630 and supplies fly ash discharged from the second blower 630 to the gas supply pipe 440.

The second intake port 610 may be formed of a pipe or duct, and may be installed horizontally with the ground or toward the ground. When the second inlet 610 faces the opposite side of the ground, when the hopper or fly ash supply pipe 20, etc., which inputs fly ash, is disconnected from the inlet 110 and separated, what remains in the hopper or fly ash supply pipe 20 This is because there is a risk that the remaining fly ash may fall into the second inlet 610 and block the second inlet 610. The second suction pipe 620 connected to the second suction port 610 serves to guide the fly ash sucked from the external space of the casing 100 through the second suction port 610 to the second blower 630. , is installed inside or outside the casing 100 and connected to the second blower 630.
