Description

Ash treatment method using eyepiece pants {DUST DISPOSAL METHOD USING BARGE FOR DOCKING}

The present invention relates to a ash processing method using the eyepiece pants. More specifically, ash (coal ash), which is buried in an unsuitable or unsuitable ash processing plant (coal ash processing plant of a thermal power plant), is safely and eco-friendlyly shipped to the offshore vessel near the ash processing plant by using an unloading pump ship as a nearby landfill. It relates to an ash processing method using the eyepiece pants that can be embedded.

The coastal landfill site constructed in Korea is buried by sea dredging soil generated from sea lanes or dredging dredging, or sea sand collected from distant seas, but it is often difficult due to the lack of landfill materials and high cost to landfill. Harvesting is often faced with opposition from fishermen or environmental groups due to environmental problems, and construction difficulties are increasing.

In addition, if many domestic companies operating thermal power plants can recycle coal ash (by ash), which is a by-product of the operation of thermal power plants, it can be expected to save costs such as the expansion of reprocessing plant or new construction. As a result, the landfills can be secured to meet the policy recommended by the Government's Law on Saving and Recycling of Resources, thereby maximizing the recycling of coal ash, a designated by-product.

In recent years, attempts have been made to use large amounts of coal ash generated from thermal power plants as landfills, but there is no experience in construction methods for excavating, transporting and reclaiming coal ash in ash processing plants. There is concern about possible fine dust and marine pollution during sea transportation, so the actual coal ash treatment is insufficient.

In addition, most coal-fired power plants have no wharf facilities to which ships can dock, or there are not enough facilities or roads to dispose a lot of coal ash, and it is not easy to deal with dust that may occur during transportation.

In this regard, it is possible to construct eyepiece facilities and scarce facilities in the ash processing plant, but it is difficult to select them right away because of the high cost and time.

In addition, even if there are sufficient eyepiece facilities, a large amount of landfill material must be transported and landfilled in a short period of time. Even when the coal ash (ship) is shipped to the docking ship docked at the eyepiece facility, if a construction method that uses small excavators or dumps for transportation is adopted. Marine pollution caused by the scattering and spillage of coal ash, which may occur at the time of loading or unloading, not only destroys the ecosystem of the nearby sea, making it difficult to survive the fish and shellfish, but also causes economic damage to the fishermen who live by fishing.

In many cases, construction was delayed or prevented due to severe opposition due to serious problems such as delayed or difficult marine ecosystem restoration.

In the present invention, the conventional mass of coal ash (ash) is shipped to the ton ship, transporting the tow ship near the landfill site and in the method of reclaiming the stone material (ash) shipped to the tow ship to landfill by pumping, the tow ship Eco-friendly berthing pants because they can efficiently ship coal ash to the ship's ships without contaminating surrounding seawater, even when there is no berthing facility installed to berthing to the ash treatment plant or when the berthing is unsafe. The problem to be solved is to provide an ash processing method.

The present invention, in order to achieve the above technical problem, environmentally friendly berths and coal ashes (ships) are shipped to the lander ship to the land ship ships coal landfills (ash) embedded in an unsafe or unsafe ash processing plant to transport landfills It provides a method of landfill pumping pumping. For this purpose

First, they use pants that serve as eyepieces. That is, the pants are used as a docking facility that can be docked by the ton ship so that ash can be shipped from the pants to the ton ship.

At this time, the ash is sedimented with sewage water from the berthing pants and sediment water mixed with fine particles is recycled back to the ashing treatment plant to prevent marine pollution caused by the sewage water.

Second, in order to obtain the precipitated ash, the eyepiece pants are installed with a immersion battery in which leachate of sewage water is settled, and the filthy water mixed with fine particles formed by the precipitated ash is stored in filthy water divided into a immersion battery and a partition wall. Will be gathered in the magazine.

At this time, the polluted water mixed with the fine particles collected in the polluted water reservoir is recycled to the ash processing plant using the polluted water recycling pump.

Third, the operation of the pump dredger in the ash treatment plant may be difficult due to the wastewater recirculation, so that the seawater suction pipe is installed in the wastewater recirculation pump to take outboard seawater, so that the inhaled seawater is recycled through the wastewater recirculation pump. To be supplied.

Fourth, the immersion battery and the filthy water storage device installed in the eyepiece pants installed sluice water to control the height so that only the filthy water mixed with the fine particles at a predetermined height flows out of the filthy water (the fine particle mixed filth) Can be automatically collected into the wastewater reservoir.

The scope of the present invention is shown by the following claims rather than the above description, and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included in the scope of the present invention. do.

The ash processing method using the eyepiece pants according to the present invention is

First, if there is no wharf or water dock, which is a facility to which ships such as ash processing plants of thermal power plants are docked, or there are inadequate facilities, coal ash (hoe) can be shipped to the tow ship without such facilities.

Second, by recycling the coal ash (ash) in the ash treatment plant of the thermal power plant as landfill material, it is possible to recycle coal ash, which is a designated by-product of the thermal power plant.

Third, it is economical as a construction method that can ship, transport, and reclaim a large amount of coal ash in a short period of time.

Fourth, it protects marine ecosystems by preventing environmental pollution due to scattering and spills during the shipment, transportation, and reclamation of coal ash.

Fifth, fine particles which are not suitable for landfill are recycled together with wastewater and recycled to the ash treatment plant, thereby having the effect of selecting the landfill material by high-quality coal ash (ash) from which fine particles have been removed.

[Eyepiece pants (100)]

1, 2 and 3 is an ash processing flow chart according to the ash processing center, the eyepiece pants, the ton ship, the landfill of the present invention, the eyepiece pants, tow ship and ash treatment plant is shown schematically.

Here, the meaning of the schematic diagram means that the detailed mechanical configuration is indicated as the core configuration for understanding.

Barge is a flat bottom cargo carrier used in canals, rivers and ports.

The present invention is to use the pants as a docking facility that can be docked by the ton ship 200 for transportation.

That is, as shown in Figure 1, the ash processing plant (400, coal ash processing plant) such as a thermal power plant is usually installed adjacent to the coast, but the ash processing plant is used as a place for simple reclamation, so the facilities for reprocessing ash are installed. Most of the time it is not.

In particular, since ash is buried in the form of powder or powder in the ash processing plant 400, a berthing facility that can be docked by the ash transport towship 200 that can be transported by shipping ash for transportation and transport through the sea is required. Done.

However, when such an eyepiece facility is not provided in the ash processing plant 400, the construction method of carrying and carrying out ashes formed in the form of powder or powder using a general excavator or a dump is inevitably adopted.

However, in this case, the problems such as civil complaints arise due to contamination due to scattering of meetings and spills.

Thus, the present invention first installs the eyepiece pants 100 on the nearby sea of the ash processing plant 400 so that the ashes from the ash processing plant 400 can be shipped to the ash transporting towing vessel 200 set in the nearby sea.

Thus, the towing vessel 200 is docked to the eyepiece pants 100 so that the ashes of the eyepiece pants 100 can be shipped to the towing vessel 200 for recirculation.

At this time, the ash is to be present in the form of waste water in the ash processing plant and adopts a manner in which the waste water (A1) is pumped and pumped to the eyepiece 100.

Therefore, in the treatment plant 400, a pump dredger 300 capable of pumping and pumping the filthy water A1 is disposed, and the ash of the treatment plant 400 is mixed with seawater so as to pump and pump the ash. It will make the soil dirty.

To this end, it is possible to use the seawater suction pipe 160 and the wastewater recirculation pump 130 installed in the eyepiece pants 100 will be described later.

The eyepiece pants 100, the immersion battery 110 that can precipitate ash from the pumped pumped filthy water (A1), as shown in Figure 1 and 2, leachate water (A2 mixed fine particles except the precipitated ash) The wastewater reservoir 120, the wastewater recirculation pump 130, the water gate 140, the partition wall 150, and the seawater suction pipe 160 for storing separately) are configured.

First, the needle needle battery 110 is installed in the eyepiece pants 100 in the form of a water tank having a certain depth as shown in FIG. 2 through the pipe pipe 310 connected to the pump dredger 300 installed in the ash processing plant 400 It is the place where the water A1 is pumped and conveyed.

At this time, the discharge pipe 310 is connected to the sedimentation basin induction pipe 111 installed extending into the internal needle battery 110.

The sedimentation basin induction pipe 111 is to be installed to extend to the inside of the penetrating cell 110, but to be disposed at a sufficient distance from the water gate 140, which will be described later, so that the sedimentation basin induction pipe 111 is sufficient, In order to slow down the flow rate of the conveyed effluent, it is preferable that two or more sedimentation basin induction pipe outlets 112 are installed.

Thus, ash (C) of the effluent water (A1) introduced into the needle cell 110 is precipitated in the lower portion of the needle cell 110 by its own weight.

The polluted water (A1) is fine particles remain when ash (C) is precipitated. The polluted water (A2) in which these fine particles are mixed is the filthy water reservoir 120 divided into the piercing battery 110 and the partition wall 150. To be gathered).

To this end, the partition wall 150 is provided with a sluice gate 140 to adjust the height. Flowing through the sluice gate 140 to the polluted water reservoir 120 is to be collected.

In this case, the sluice gate 140 may be installed between the partition walls 150 so as to be able to adjust the height of the sluice gate by the lifting means.

As such, the polluted water A2 mixed with the fine particles collected in the wastewater reservoir 120 through the sluice gate 140 is recycled to the ash treatment plant 400 through the wastewater recirculation pump 130.

As a result, the precipitated ash (C) has an advantage that it is very effective in using as a landfill material because there is little mixed with fine particles, and the mixed wastewater (A2) is recycled to the ash treatment plant 400 by the nearby sea It can have the effect of not contaminating.

The wastewater recirculation pump 130 is installed on the bottom of the berth adjacent to the wastewater reservoir 120, and the wastewater recycle pump 130 and the wastewater reservoir 120 are in the wastewater recirculation pump suction pipe 131 Are connected to each other.

At this time, the waste water recirculation pump suction pipe 131 is connected to the waste water suction opening and closing valve 132 installed inside the waste water reservoir 120 so that the fine particles are mixed to control the amount of recycled mixed water (A2). Done.

At this time, the waste water recirculation pump suction pipe 131 is connected to the suction port of the waste water recirculation pump 130.

In addition, the outlet of the wastewater recirculation pump 130 is connected to the wastewater conveying pipe 134, which is extended to the ash treatment plant 400 through the wastewater recirculation pump discharge pipe 133, and mixed with fine particles (A2) It is to be recycled from the waste water reservoir 120 to the ash processing plant 400.

At this time, when the amount of the filthy water (A2) mixed with the fine particles recycled to the ash treatment plant 400 is reduced, it may be difficult to operate the pump dredger 300 installed in the ash treatment plant 400.

Therefore, a method for additionally introducing seawater (A3) to the ash processing plant 400 is required. For this, the present invention uses the seawater suction pipe 160.

The seawater suction pipe 160 is connected to the wastewater recirculation pump suction pipe 131, so that the seawater (A3) from the intake tank (Scheast) is introduced into the wastewater recirculation pump suction pipe 131 through the seawater suction pipe 160 to fine Seawater (A3) is to be replenished to the mixed water (A2) mixed particles.

At this time, the wastewater recirculation pump suction pipe 131 and the seawater suction pipe 160 may adjust the amount of seawater A3 introduced by the seawater suction opening / closing valve 161.

The seawater intake opening and closing valve 132 and the seawater intake opening and closing valve 161 connected to the wastewater recirculation pump suction pipe 131 installed in the wastewater storage 120 may be manually operated, and the inflow amount of the wastewater or seawater It can be operated automatically in consideration of the light and the like to improve the efficiency of the operation.

[An ash treatment method using the eyepiece pants 100]

First, as shown in FIG. 1, the ash processing plant 400 may be a kind of landfill formed on a coastal area near a thermal power plant, and ash such as coal ash is embedded in the ash processing plant 400.

In the ash treatment plant 400, the water dredging water (A3) of the predetermined water level must be introduced in advance to operate the dredger 300, and the sea water (A3) is a seawater suction pipe (160) connected to the wastewater recirculation pump (130) Inflow through it.

The sea water (A3) and ash (C) is seen to be accommodated in the ash processing plant 400 in the form of mixed waste water (A1).

Accordingly, the eyepiece 100 of the present invention is set on the nearby sea of the ash processing plant 400.

This is done by setting the eyepiece pants 100 to the vicinity of the ash processing plant 400 using a tugboat not shown.

The eyepiece pants 100 are provided with a contaminated water reservoir 120 as described above.

Accordingly, as shown in FIG. 2, the discharge pipe 310 connected to the pump dredger 300 and the sedimentation basin induction pipe 111 extending into the throttle cell 110 are connected to each other.

As a result, it can be seen that the filthy water (A1) accommodated in the ash treatment plant 400 can be pumped and pumped into the internal needle battery 110.

Next, the ash (C) of the filthy water (A1) pumped and pumped into the lancet battery 110 is to be precipitated with time in the lancet battery 110, which is only to the ash transport vessel 200 For loading.

When the ash (C) is completed to some extent in the lower part of the inside of the immersion battery (110), the filthy water (A1) becomes the filthy water (A2) mixed with fine particles.

Waste water (A2) mixed with these fine particles is recycled to the treatment plant (400).

To this end, in the immersion battery divided by the filthy water reservoir 120 and the partition wall, by adjusting the height of the sluice gate 140 installed in the partition wall 150, the supernatant water of the filthy water (A2) in which the fine particles are mixed is the sluice ( It is to be guided to the wastewater reservoir 120 through the 140 to be collected.

When a certain time has elapsed, the water level of the wastewater reservoir 120 is raised. At this time, the wastewater recirculation pump 130 installed around the wastewater reservoir 120 is operated.

The inlet of the wastewater recirculation pump 130 is connected to the wastewater reservoir 120 by the wastewater recirculation pump suction pipe 131, and the wastewater recirculation pump suction pipe 131 is installed on the inside of the wastewater reservoir 120. Since it is connected to the water intake opening and closing valve 132 to operate the waste water recirculation pump 130 while controlling the amount of mixed fine water (A2).

In addition, the waste water recycle pump discharge pipe 133 is connected to the discharge port of the wastewater recirculation pump 130, the wastewater recycle pump discharge pipe 133 is a wastewater transport pipe 134 extending to the ash treatment plant 400 Since it is connected to the wastewater containing fine particles (A2) can be recycled from the wastewater reservoir 120 to the treatment plant 400.

At this time, when there is a need for replenishing the outboard seawater to the ash treatment plant 400 due to the lack of fine water (A2) containing fine particles, the seawater suction opening and closing of the seawater suction pipe 160 connected to the wastewater recirculation pump suction pipe 131. Open the valve 161 so that the outboard seawater A3 is supplied to the wastewater recirculation pump 130, and the wastewater A2 mixed with the seawater A3 and the fine particles is connected to the wastewater recirculation pump 130. Wastewater (A2) containing fine particles mixed with seawater (A3) through the wastewater recirculation pump discharge pipe 133 and the wastewater transport pipe (134) to be easily recycled to the ash treatment plant (400).

The configuration for supplying the mixed water (A2) or seawater (A3) mixed with such fine particles generally sets the flow amount or pressure of the fluid at a constant level, and then detects the fine particles by detecting when they are not set or not. To automatically open and close each of the sewage water inlet / opening valve 132 and the seawater inlet / outlet valve 161 so that the mixed water (A2) or the seawater supply is selectively or simultaneously supplied, or the supply of the sewage water Depending on the quantity, it can be opened or closed manually.

Next, when the amount of ash (C) precipitated in the piercing cell 110 of the eyepiece 100 is sufficiently accumulated, equipment such as an excavator (not shown), a conveyor belt (not shown), etc. Ship using.

At this time, since the ash (C) to be shipped is a state of moisture is very low probability of problems such as scattering.

Accordingly, when the ship is completed in the round transportation ton ship 200, the tow ship 200 is docked to the unloading pump ship 700 located near the landfill 600 as shown in FIG. 3.

Thus, the ash shipped to the docking ton ship 200 is docked pumped by the unloading pump line 700 to the landfill.

That is, the ash shipped in the towing ship 200 for ash transportation disturbs the seawater (A3), and using the dredging pump 710 installed in the unloading pump ship 700, the seawater is sucked with the ash and then reclaimed land ( The ash is pumped to the landfill 600 through the discharge pipe 610 connected to 600 to bury the ash.
